Fig. 1 is the block diagram that diagram performs the composed component of UE and BS of the present invention.

UE runs as reflector on uplink, and runs as receiver on the uplink.On the contrary, BS runs as receiver on uplink, and runs as reflector on the uplink.

UE and BS comprises: antenna 500a and 500b, for receiving information, data, signal and/or message; Reflector 100a and 100b, for launching message by control antenna; Receiver 300a and 300b, for carrying out receipt message by control antenna; And memory 200a and 200b, for storing the various types of information relevant to the communication in wireless communication system.UE and BS comprises processor 400a and 400b of the composed component being operably connected to the reflector, receiver and the memory that comprise at UE or BS further, for performing the present invention by controlling composed component.Reflector 100a, the receiver 300a of UE, memory 200a and processor 400a can be configured to independently parts by the chip is separated, or, can by two or more to be individually integrated in a chip.Reflector 100b, receiver 300b, the memory 200b of BS can be configured to independently parts by the chip be separated with processor 400b, or, two or more can be integrated in a chip.Reflector and receiver can be integrated in the single transceiver in UE or BS.

Antenna 500a and 500b externally launches from the signal of reflector 100a and 100b generation or from outer received signal, and provides received signal to receiver 300a and 300b.Antenna 500a and 500b is also referred to as antenna port.Each antenna port can correspond to a physical antenna, or can be configured by the combination of the physical antenna elements more than.The signal launched by each antenna port can not be received device 20 and decompose.The reference signal (RS) of launching accordingly with antenna port defines the antenna port observed from UE, and make UE can perform channel estimating for antenna port, and whether be from the single radio channel of a physical channel with channel or have nothing to do from the compound channel of the multiple physical antenna elements comprising antenna port.That is, the channel that antenna port is defined as making to launch symbol on antenna port can draw from the channel launching another symbol by it on same antenna port.If reflector and receiver support wherein use multiple antenna to transmit and receive the multiple-input and multiple-output (MIMO) of data, then each of this reflector and receiver can be connected to two or more antenna.

Usually, the integrated operation of the module of processor 400a and 400b control UE or BS.Particularly, processor 400a and 400b can perform for realizing various controlling functions of the present invention, based on medium education (MAC) the frame conversion and control function of service characteristic and communication environments, for controlling the energy saver mode function of idle mode operations, handoff functionality, certification and encryption function etc.Processor 400a and 400b can be called as controller, microcontroller, microprocessor or microcomputer.Meanwhile, processor 400a and 400b can be configured to hardware, firmware, software, or the combination of hardware, firmware and software.In hardware configuration, processor 400a and 400b can comprise and be configured to realize application-specific integrated circuit (ASIC) of the present invention (ASIC), digital signal processor (DSP), digital signal processor (DSPD), programmable logic device (PLD), field programmable gate array (FPGA) etc.In firmware or software merit rating, firmware or software can be configured to comprise the module, process, function etc. that perform function of the present invention or operation.Be configured to realize firmware of the present invention or software can be included in processor 400a and 400b or can be stored in memory 200a and 200b and to be performed by processor 400a and 400b.

Reflector 100a and 100b encodes and modulation is launched into outside signal and/or data by processor 400a and 400b or by the scheduler schedules being connected to processor, and launches signal and/or the data of modulation to antenna 500a and 500b.Such as, reflector 100a and 100b is changed to K layer by the stream compression that demultiplexing, Channel Coding and Modulation will be launched.Transmitting processor via reflector launches K layer by antenna 500a and 500b.Can transmit according to process and come reflector 100a and 100b and receiver 300a and 300b of differently configuration UE and BS with the operation of Received signal strength.

Fig. 2 is shown in the example arrangement of the reflector in each of UE and BS.The operation of reflector 100a and 100b is described in more detail below with reference to Fig. 2.

See Fig. 2, each of reflector 100a and 100b comprises scrambler 301, modulation mapper 302, layer mapper 303, precoder 304, resource element (RE) mapper 305 and OFDM (OFDM) signal generator 306.

Reflector 100a and 100b can launch more than a code word.The coded-bit of each code word of scrambler 301 scrambling, for launching on the physical channel.Code word can be called as data flow, and is equal to the data block provided from MAC layer.The data block provided from MAC layer is called as transmission block.

The bit modulation of scrambling is complex-value modulation symbol by modulation mapper 302.Scrambler bits can be modulated to the complex-value modulation symbol of the position of representative on signal constellation (in digital modulation) by modulation mapper 302 according to predetermined modulation schemes.Modulation scheme is not limited, and m phase shift keying (m-PSK) and m quadrature amplitude modulation (m-QAM) may be used for the data of modulating-coding.

The modulation symbol of complex values is mapped to one or more emission layer by layer mapper 303.

Layer mapper 303 can the complex modulation symbols of precoding on each layer, to be launched by antenna port.More specifically, precoder 304 is by being used for multiple transmitting antenna 500-1 to 500-N with MIMO scheme process _tcomplex-value modulation symbol produce antenna special symbol, and distribute this antenna special symbol to RE mapper 305.That is, emission layer is mapped to antenna port by precoder 304.The output x of layer mapper 303 can be multiplied by N by precoder 304 _t× M _tpre-coding matrix W, and with N _t× M _fthe form of matrix z carrys out the product of Output rusults generation.

RE mapper 305 will be used for the complex-value modulation sign map of corresponding antenna port/be assigned to RE.RE mapper 305 can be used for the complex-value modulation symbol of corresponding antenna port to suitable sub carries allocation, and can according to UE come multiplexing they.

Ofdm signal generator 306 modulates the complex-value modulation symbol for corresponding antenna port by OFDM or single carrier frequency division multiplexing (SC-FDM), that is, antenna special symbol, produces complex values time domain OFDM or SC-FDM mark signal thus.Ofdm signal generator 306 can perform inverse fast fourier transform (IFFT) for antenna special symbol, and inserts Cyclic Prefix (CP) in resultant IFFT time-domain symbol.OFDM symbol is rear by transmitting antenna 500-1 to 500-N at digital-to-analogue conversion, frequency upooaversion etc. _tbe launched into receiver.Ofdm signal generator 306 can comprise IFFT module, CP inserter, digital to analog converter (DAC), Frequency up-converter etc.

Meanwhile, if reflector 100a and 100b adopts SC-FDMA to be used for the transmitting of code word, then reflector 100a and 100b can comprise discrete Fourier (DFT) module 307 (or fast fourier transform (FFT) module).DFT module performs DFT or FFT for antenna special symbol, and exports DFT/FFT symbol to RE mapper 305.SC-FDMA is the launch scenario transmitted for the peak-to-average power ratio (PAPR) by reducing signal or cubic metric (CM).According to SC-FDMA, can obstructed overpower amplifier nonlinearity distortion zone and transmitting.Therefore, even if when reflector is with the power transmission signal lower than the power in conventional OFDM scheme, receiver also can receive the signal meeting constant intensity or error rate.That is, the power consumption of reflector can be reduced by SC-FDMA.

In conventional ofdm signal generator, the signal that each carrier wave carries while by IFFT by multi-carrier modulation (MCM) parallel launch simultaneously, reduce the efficiency of power amplifier thus.On the other hand, in SC-FDMA, information carried out DFT/FFT before signal is mapped to subcarrier.PAPR is increased by DFT/FFT effect by the signal of DFT module 307.The signal of DFT/FFT process is mapped to subcarrier, by IFFT process, and is converted into time-domain signal.That is, SC-FDMA reflector performs DFT or FFT operation taking a step forward of ofdm signal generator, the PAPR transmitted is increased in IFFT input stage, and is finally reduced while again by IFFT.The program is called as DFT and expands OFDM (DFT-s-OFDM), because seem to seem to add DFT module (or FFT module) 307 before existing ofdm signal generator.

SC-FDMA should meet single carrier property.Fig. 3 maps the example of incoming symbol in a frequency domain to subcarrier while being shown in and meeting single carrier property.If according to one of scheme shown in Fig. 3 (a) and 3 (b) by DFT allocation of symbols to subcarrier, then can obtain and meet transmitting of single carrier property.Fig. 3 (a) illustrates centralized mapping, and Fig. 3 (b) illustrates distributed mapping.

Meanwhile, reflector 100a and 100b can adopt sub-clustering DFT to expand OFDM (DFT-s-OFDM).Sub-clustering DFT-s-OFDM is the revision of conventional SC-FDMA.In sub-clustering DFT-s-OFDM, be divided into the sub-block of predetermined quantity by the signal of DFT/FFT module 307 and precoder 304, and be mapped to subcarrier in discontinuous mode.Fig. 4 to 6 illustrates the example by sub-clustering DFT-s-OFDM, incoming symbol being mapped to single carrier.

Fig. 4 diagram is used for the signal processing operations output of DFT process sampling being mapped to single carrier in sub-clustering SC-FDMA.Fig. 5 and 6 is shown in the signal processing operations in sub-clustering SC-FDMA, the output of DFT process sampling being mapped to multicarrier.Fig. 4 illustrates the application of sub-clustering SC-FDMA in carrier wave, and the application of Fig. 5 and 6 diagram intercarrier sub-clustering SC-FDMA.Fig. 5 diagram is produced by the signal of single IFFT block in the following cases: be aligned in the subcarrier spacing between continuous component subcarrier when distributing component carrier in a frequency domain continuously.Fig. 6 diagram is produced by the signal of multiple IFFT block when distributing component carrier in a frequency domain discontinuously.

Fig. 7 is shown in the signal processing operations in segmentation SC-FDMA.

Because the quantity of DFT block equal IFFT block quantity and therefore DFT block and IFFT block corresponding one to one, so segmentation SC-FDMA is the DFT expansion of conventional SC-FDMA and the simple expansion of IFFT subcarrier mapping structure, and NxSC-FDMA or NxDFT-s-OFDMA can be expressed as.In the disclosure, segmentation SC-FDMA comprises all these projects.See Fig. 7, in segmentation SC-FDMA, all modulation symbols be in the time domain divided into N group (wherein, N be greater than 1 integer), and carry out DFT process in units of group, to remove single carrier property constraint.

Return see Fig. 2, receiver 300a and 300b runs with the backward of the operation with reflector 100a and 100b.Receiver 300a and 300b decodes and the radio signal of antenna 500a and 500b from external reception is passed through in demodulation, and transmits the signal of demodulation to processor 400a and 400b.Antenna 500a and 500b being connected to each of receiver 300a and 300b can comprise N _rindividual reception antenna.The signal received by each reception antenna is resumed as baseband signal, and is then resumed the original data stream into reflector 100a and 100b launches by multiplexing and MIMO demodulation.Each of receiver 300a and 300b can comprise: signal recuperation device, for Received signal strength is reverted to baseband signal; Multiplexer, for the signal of multiplexing reception and process; And channel demodulator, for being demodulated into code word by multiplexing signal stream.Signal recuperation device, multiplexer and channel demodulator can be configured to integration module or the independently module of the function for performing them.More specifically, signal recuperation device can comprise: analog to digital converter (ADC), for analog signal is converted to digital signal; CP remover, for removing CP from digital signal; FFT module, for producing frequency domain symbol by performing FFT for the signal eliminating CP; And RE de-mapping device/equalizer, for from frequency domain symbol level restoration antenna special symbol.Multiplexer recovers emission layer from antenna special symbol, and channel demodulator recovers the code word of being launched by reflector from emission layer.

Meanwhile, if receiver 300a and 300b receives the signal launched by SC-FDMA described with reference to figure 3 to 7, then each of receiver 300a and 300b comprises IFFT module further.The antenna special symbol that IDFT/IFFT module I DFT/IFFT process is recovered by RE de-mapping device, and export IDT/IFFT symbol to multiplexer.

Although each having described reflector 100a and 100b in Fig. 1 to 7 comprises scrambler 301, modulation mapper 302, layer mapper 303, precoder 304, RE mapper 305 and ofdm signal generator 306, can further consider and scrambler 301, modulation mapper 302, layer mapper 303, precoder 304, RE mapper 305 and ofdm signal generator 306 are covered in each of processor 400a and 400b of reflector 100a and 100b.Equally, although each having described receiver 300a and 300b in Fig. 1 to 7 comprises signal recuperation device, multiplexer and channel demodulator, can further consider and signal recuperation device, multiplexer and channel demodulator are covered in each of processor 400a and 400b of receiver 300a and 300b.For convenience of description, explanation below providing under following prerequisite: scrambler 301, modulation mapper 302, layer mapper 303, precoder 304, RE mapper 305 and ofdm signal generator 306 is (when SC-FDMA scheme, comprise DFT module 307 further) be included in and be configured to and control in reflector 100a and 100b that its processor 400a with 400b operated is separated, further, signal recuperation device, multiplexer and channel demodulator are included in and are configured to and control in receiver 300a and 300b that its processor 400a with 400b operated is separated.But, even if scrambler 301, modulation mapper 302, layer mapper 303, precoder 304, RE mapper 305 and ofdm signal generator 306 (with 307) is included in processor 400a and 400b, and signal recuperation device, multiplexer and channel demodulator are (when SC-FDMA scheme, comprise IFFT module further) be included in processor 400a and 400b, also can apply embodiments of the invention in an identical manner.

Fig. 8 illustrates the exemplary radio frame structure used in a wireless communication system.Specifically, Fig. 8 (a) is shown in the radio frame of the frame structure Class1 (FS-1) in 3GPPLTE/LTE-A system, and Fig. 8 (b) is shown in the radio frame of the frame structure type 2 (FS-2) in 3GPPLTE/LTE-A system.The frame structure of Fig. 8 (a) can be applied to Frequency Division Duplexing (FDD) (FDD) pattern and half FDD (H-FDD) pattern, and the frame structure of Fig. 8 (b) can be applied to time division duplex (TDD) pattern.

See Fig. 8, in 3GPPLTE/LTE-A, radio frame has the length of 10ms (307200Ts), comprises the subframe of 10 equal sizes.Can by 10 of a radio frame frame number.At this, T _sbe the sampling time, be expressed as T _s=1/ (2048x15kHz).Each subframe is that 1ms is long, comprises two time slots.Can from 20 time slots of 0 to 19 sequentially numbering radio frame.Each time slot has the length of 0.5ms.The time of launching needed for a subframe is defined as Transmission Time Interval (TTI).(or radio frame index) can be numbered by radio frame, subframe numbering (or subframe index) or time-gap number (or time slot index) carrys out recognition time resource.

Different radio frames can be configured according to dual-mode.Such as, in fdd mode, because distinguish downlink transmission and uplink transmit by frequency, so radio frame comprises downlink subframe or uplink sub-frames.

On the other hand, in tdd mode, because distinguish downlink transmission and uplink transmit by the time, so the subframe in frame is divided into downlink subframe and uplink sub-frames, table 1 illustrates the example uplink-downlink configuration in tdd mode.

[table 1]

In Table 1, D represents downlink subframe, and U represents uplink sub-frames, and S represents special subframe.Special subframe comprises down link pilot timeslot (DwPTS), protective time slot (GP), uplink pilot time slot (UpPTS) three fields.DwPTS is the time slot being preserved for downlink transmission, and UpPTS is the time slot being preserved for uplink transmit.

Fig. 9 diagram exemplary downlink/up link (DL/UL) structure of time slot in a wireless communication system.Specifically, Fig. 9 illustrates the structure of the resource grid of 3GPPLTE/LTE-A system.There is a resource grid in each antenna port.

See Fig. 9, time slot comprises multiple OFDM (OFDM) symbol in the time domain, and comprises multiple Resource Block (RB) in a frequency domain.OFDM symbol can represent a symbol duration.RB comprises multiple subcarriers in a frequency domain.OFDM symbol can be called as OFDM symbol, SC-FDM symbol etc. according to Multiple Access scheme.The quantity of the OFDM symbol of each time slot can depend on channel width and Cyclic Prefix (CP) length and change.Such as, comprise 7 OFDM symbol at the next time slot of the situation of normal CP, and comprise 6 OFDM symbol at the next time slot of the situation of expansion CP.Although in order to subframe is depicted as the time slot with 7 OFDM symbol by illustrative object in fig. 8, embodiments of the invention are also applicable to the subframe of the OFDM symbol with any other quantity.Comprise the resource that an OFDM symbol is multiplied by a subcarrier and be called as resource element (RE) or single-tone (tone).

See Fig. 9, can by comprising N ^dL/UL _rBn ^rB _scindividual subcarrier and N ^dL/UL _symbthe resource grid of individual OFDM or SC-FDM symbol is described in the signal launched in each time slot.N ^dL _rBrepresent the quantity of the RB in DL time slot, and N ^uL _rBrepresent the quantity of the RB in UL time slot.N ^dL _rBand N ^uL _rBdepend on DL transmitted bandwidth and UL transmitted bandwidth respectively.Each OFDM symbol comprises N in a frequency domain ^dL/UL _rBn ^rB _scindividual subcarrier.The quantity of the subcarrier in a carrier wave is determined according to FFT value.The type of subcarrier can be divided into the data subcarrier launched for data, the RS subcarrier launched for RS and the null subcarrier for the protection of band and DC component.Null subcarrier for DC component keeps not used and being mapped to carrier frequency f in the process producing ofdm signal ₀.This carrier frequency is also referred to as centre frequency.N ^dL _symbrepresent the quantity of OFDM or the SC-FDMA symbol in DL time slot, N ^uL _symbrepresent the quantity of OFDM or the SC-FDMA symbol in UL time slot, and N ^rB _screpresent the quantity of the subcarrier of a formation RB.

In other words, Physical Resource Block (PRB) is defined as N in the time domain ^dL/UL _symbindividual continuous OFDM symbol or SC-FDMA symbol are multiplied by N in a frequency domain ^rB _scindividual continuous subcarrier.Therefore, a PRB comprises N ^dL/UL _symb× N ^rB _scindividual RE.

Each RE in resource grid can be identified (k, l) uniquely by the index in time slot.K is that scope is from 0 to N ^dL/UL _rB× N ^rB _scthe frequency domain index of-1, and l is that scope is from 0 to N ^dL/UL _symbthe time Domain Index of-1.

Figure 10 diagram exemplary DL subframe structure in a wireless communication system.

See Figure 10, each subframe can be divided into control area and data area.Control area comprises the one or more OFDM symbol from the first OFDM symbol.The quantity of the OFDM symbol used in the control area in subframe can be configured in independently in each subframe.The information of the quantity about OFDM symbol is launched by Physical Control Format Indicator Channel (PCFICH).BS can launch various control information by control area to one or more UE.Control information is launched, physical downlink control channel (PDCCH), PCFICH and physics can be distributed to control area and mix arq indicating channel (PHICH).

BS on PDCCH to each UE or UE group launch be associated with as the paging channel (PCH) of transfer channel and the Resourse Distribute of downlink sharied signal channel (DL-SCH) information, UL scheduling grant, mixed arq (HARQ) information, downlink allocation index (DAI) etc.

BS can launch data for UE or UE group by data area.The data of being launched by data area are also referred to as user data.For the transmitting of user data, physical down link sharing channel (PDSCH) can be distributed to data area.PCH and DL-SCH is launched by PDSCH.The data of being launched by PDSCH are read in the control information that UE can be launched via PDCCH by decoding.Launched by PDCCH and be used to indicate PDSCH data and be launched into the information of which UE or UE group and be used to indicate the information how UE or UE group should receive the decode PDSCH data.Such as, assuming that use radio net temporary mark (RNTI) ' A ' to carry out CRC shelter specific PDCCH, and launch about use radio resource ' B ' (such as by specific sub-frame, frequency location) and the information of data that uses transport format information ' C ' (such as, transmitting block size, modulation scheme, coded message etc.) to launch.Then, UE in the cell uses its RNTI information to monitor PDCCH.The UE with RNTI ' A ' receives PDCCH, and receives by the information of the PDCCH received the PDSCH indicated by ' B ' and ' C '.

Multiple PDCCH can be launched in control area.UE can monitor multiple PDCCH to detect its PDCCH.The down link control information (DCI) carried by PDCCH can be different in size and object according to DCI format, and different in size according to encoding rate.

DCI format can be applied independently for each UE, and can in a subframe PDCCH of multiplexing multiple UE.The PDCCH of each UE can, by chnnel coding independently, make it possible to add cyclic redundancy check (CRC) (CRC) to PDCCH.Use the unique identifier of each UE to shelter CRC, make each UE can receive its PDCCH.But, because UE does not know in fact the position that its PDCCH is launched into, so require that UE performs blind Detecting (being also referred to as blind decoding), until receive the PDCCH with its identifier for all PDCCH of the DCI format of the correspondence in each subframe.

Figure 11 diagram example UL subframe structure in a wireless communication system.

Control area and data area can be divided in a frequency domain see Figure 11, UL subframe.One or more physical uplink control channel (PUCCH) can be distributed to carry uplink control information (UCI) to control area.One or more physical uplink link shared channels (PUSCH) can be distributed with carrying user data to data area.If UE adopts SC-FDMA scheme to be used for uplink transmit, then can not launch PUCCH and PUSCH, to keep single carrier property simultaneously.

The UCI carried by PUCCH can be different in size and object according to PUCCH format, and different in size according to encoding rate.Such as, PUCCH format can be defined as follows.

[table 2]

In the UL sub-frame, the subcarrier away from direct current (DC) subcarrier is used as control area.In other words, the subcarrier being positioned at the two ends of UL transmitted bandwidth is assigned to be launched for UL control information.DC subcarrier is retained and not be used in signal transmitting, and is mapped to carrier frequency f in the frequency upooaversion process caused by OFDM/SC-FDMA signal generator 306 ₀.

To the RB in subframe to dividing the PUCCH being used in UE.The RB that RB is right takies different subcarriers in two time slots.This is called as and exceedes the right frequency hopping of RB that boundary of time slot distributes to PUCCH.But if do not use frequency hopping, then RB is to taking identical subcarrier.Have nothing to do with frequency hopping, the PUCCH for a UE is assigned to a RB couple in a subframe, and therefore, in a UL subframe, identical PUCCH launches once by a RB in each time slot, twice altogether.

Below, the RB launched for each PUCCH of a subframe is to being called as PUCCH region or PUCCH resource.In addition, for convenience of description, the PUCCH carrying acknowledgement/non-acknowledgement (ACK/NACK) is called as ACK/NACKPUCCH.The PUCCH of Bearer Channel quality indicator (CQI)/precoding matrix indicators (PMI)/order information (RI) is called as channel condition information (CSI) PUCCH, and the PUCCH carrying dispatch request (SR) is called as SRPUCCH.

Carry out the assignment from BS to UE according to explicit or implicit aspect and be used for the PUCCH resource of UCI transmitting.

UCI, such as ACK/NACK, CQI, PMI, RI, SR etc. can be launched by the control area of UL subframe.

In a wireless communication system, the mutual transmitting/receiving signal of BS and UE or data.If BS/UE is to UE/BS transmitting data, then UE/BS decodes the data received.If successfully decoded data, then launch ACK to BS/UE.If data decode failure, then launch NACK to BS/UE.In 3GPPLTE system, UE receives data cell (such as from BS, and come to launch for the ACK/NACK of this data cell to BS by the determined implicit expression PUCCH resource of PDCCH resource of the schedule information being used for this data cell by carrying PDSCH).

Figure 12 diagram determines the example of the PUCCH resource of ACK/NACK.

In LTE system, do not divide to each UE the PUCCH resource being used in ACK/NACK in advance, and the multiple UE being arranged in community use multiple PUCCH resource at each time point in the mode divided.Specifically, the PUCCH resource that the ACK/NACK that the PDCCH based on the schedule information of carrying PDSCH implicitly determines UE launches, this PDSCH carries corresponding DL data.The whole region of wherein launching PDCCH in DL subframe comprises multiple control channel element (CCE), and the PDCCH launched to UE comprises one or more CCE.Each CCE comprises multiple resource element group (REG) (such as, 9 REG).When getting rid of reference signal (RS), a REG is made up of four continuous RE.UE launches ACK/NACK by the PUCCH resource of implicit expression, the PUCCH resource of this implicit expression be used in form the CCE of PDCCH received by UE index in the middle of the function of specific CCE index (such as, first or minimum CCE index) be exported or calculate.

See Figure 12, each PUCCH resource index corresponds to the PUCCH resource for ACK/NACK.As shown in Figure 12, assuming that come to launch PDSCH schedule information to UE by the PDCCH be made up of the CCE of numbering 4 to 6, so UE passes through from CCE numbering 4, the i.e. minimum CCE of PDCCH, the PUCCH deriving or calculate, such as, by PUCCH numbering 4, come to launch ACK/NACK to BS.Figure 12 illustrates an example, wherein, exists until M' CCE in DL subframe, and exists until M PUCCH resource in the UL sub-frame.Although M' can equal M, M' can be different from M, and can come mapping CCE and PUCCH resource in an overlapping manner.

Such as, PUCCH resource index can be determined as follows.

[equation 1]

n_{P U C C H}^{(1)} = n_{C C E} + N_{P U C C H}^{(1)}

At this, n ⁽¹⁾ _pUCCHthe PUCCH resource index launched for ACK/NACK, N ⁽¹⁾ _pUCCHthe signalling value received from higher level, and n _cCErepresent the minimum CCE index being used for PDCCH and launching.

Figure 13 is shown in the example communication under single carrier case.Figure 13 can correspond to the example of the communication in LTE system.

See Figure 13, general FDD wireless communication system is by a DL band and bring transmitting and receiving data corresponding to the UL that this DL is with.BS and UE transmits and receives the data and/or control information of dispatching in units of subframe.Transmit and receive data by the data area configured in UL/DL subframe, and transmit and receive control information by the control area configured in UL/DL subframe.For this reason, UL/DL subframe carrying signal on various physical channel.Although conveniently provide the explanation of Figure 13 based on FDD scheme, explanation above also can be applied to the TDD scheme by the time domain the radio frame of Fig. 8 being divided into UL frame and DL frame.

Figure 14 is shown in the example communication under multi-carrier case.

Lte-a system uses carrier aggregation or aggregated bandwidth, carrier aggregation or aggregated bandwidth by being polymerized multiple UL/DL frequency chunks to adopt wider frequency band to use wider UL/DL bandwidth.Multicarrier system or carrier aggregation (CA) system refer to the system that each multiple carrier wave with the bandwidth narrower than target bandwidth of polymerization are supported for broadband.When polymerization has multiple carrier wave of the bandwidth narrower than target bandwidth, the bandwidth of polymerization carrier wave can be limited to the bandwidth used in conventional systems, to keep the backward compatibility with legacy system.Such as, LTE system can support the bandwidth of 1.4,3,5,10,15 and 20MHz, and can be used in the bandwidth supported LTE system support the bandwidth wider than 20MHz from senior LTE (LTE-A) system that LTE system is improved.In addition, new bandwidth can be defined to support CA, and have nothing to do with the bandwidth used in conventional systems.Term multicarrier can be used interchangeably with term CA and aggregated bandwidth.Continuous CA and discontinuous CA are collectively referred to as CA.In order to reference, when only one-component carrier wave (CC) is for communication in TDD, this corresponds to the communication in the single carrier case (non-CA) of Figure 13.ULCC and DLCC is also called as UL resource and DL resource respectively.

Such as, see Figure 14, each is that 5 CC of 20MHz are to support the bandwidth of 100MHz can be polymerized it in each of UL and DL.Corresponding CC can be continuous or discontinuous in a frequency domain.Conveniently, Figure 14 illustrates the wherein bandwidth of ULCC and the situation of both symmetry identical with the bandwidth of DLCC.But, the bandwidth of each CC can be determined independently.Such as, the bandwidth of ULCC can be configured in the mode of 5MHz (ULCC0)+20MHz (ULCC1)+20MHz (ULCC2)+20MHz (ULCC3)+5MHz (ULCC4).Also can configure asymmetric CA, wherein, the quantity of ULCC is different from the quantity of DLCC.Asymmetric CA can be produced due to the restriction of available band, or can be formed by network configuration intentionally.Such as, even if when BS manages X DLCC, the frequency band that can be received by particular UE can be restricted to Y (≤X) individual DLCC.In this case, UE needs DL signal/data that monitoring is launched by Y CC.In addition, even if when BS manages L ULCC, the frequency band that can be received by particular UE can be limited to M (≤L) individual ULCC.Confined DLCC or ULCC for particular UE is called as service UL or DLCC configured in particular UE.BS can by activate the CC that be managed by BS some or all or by forbidding the CC that some CC of being managed by BS come to UE distribution provisions quantity.BS can change the CC of activation/forbidding, and changes the quantity of the CC activating/forbid.Meanwhile, BS can community specifically or UE specifically configuration UE Z the DLCC (wherein, 1≤Z≤Y≤X) that first should monitor/receive as main DLCC.And, BS can community specifically or the specific configuration UE of UE N number of ULCC (wherein, 1≤N≤M≤L) that first should monitor/receive as main ULCC.By this way, main DL or ULCC for the restriction of particular UE is also referred to as service UL or DLCC configured in particular UE.Can specific, the UE group in community specifically or UE be specifically configured for the various parameters of CA.

Once BS community specifically or UE specifically distribute available CC to UE, then do not forbid distributed CC at least one, to distribute to the overall CC of UE except non-reconfigurable or UE is switched.Below, except non-reconfigurable to be distributed otherwise the CC do not forbidden is called as main CC (PCC) to the overall CC of UE, and the CC that BS freely can activate/forbid is called as auxiliary CC (SCC).Single carrier communication uses a PCC for the communication between UE and BS, and does not use SCC to come for communication.Meanwhile, also PCC and SCC can be distinguished based on control information.Such as, specific control information can be set to by means of only specific CC transmitting/receiving.Specific CC like this can be called as PCC, and other one or more CC can be called as one or more SCC.Such as, the control information of being launched by PUCCH can correspond to so specific control information.Therefore, if the control information of launching on PUCCH can be transmitted into BS by means of only PCC from UE, then the ULCC that wherein there is the PUCCH of UE can be called as ULPCC, and other one or more ULCC can be called as one or more ULSCC.As another example, if use the specific CC of UE, then this particular UE can from the DL synchronizing signal (SS) of BS reception as specific control information.In this case, this particular UE makes for setting up the synchronous DLCC of initial DL time (namely by receiving DLSS, for attempting the DLCC of the network accessing BS) can DLPCC be called as, and other one or more DLCC can be called as one or more DLSCC.According in the communication system of LTE-A version 10, multi-carrier communication uses a PCC for each UE and does not use SCC or use one or more SCC.But this is the definition according to LTE-A, and each UE can be allowed to use the communication of multiple PCC in future.PCC can be called as main CC, grappling CC or main carrier, and SCC can be called as auxiliary CC or subcarrier.

LTE-A uses the concept of community to carry out managing radio resources.Community is defined as the combination of DL resource and UL resource, that is, the combination of DLCC and ULCC.At this, UL resource is not indispensable component.But this is defined in current LTE-A standard, and in future, can allows to be used alone UL resource and come allocating cell.Therefore, can be used alone DL resource or use DL resource and UL resource to come allocating cell.When supporting CA, association between the carrier frequency and the carrier frequency of UL resource (or ULCC) of DL resource (or DLCC) can be indicated by system information.Such as, the combination of DL resource and UL resource can be indicated by system information block type 2 (SIB2).At this, carrier frequency indicates the centre frequency of each community or CC.Main plot (PCell) can be called as in the upper community run of basic frequency (or PCC), and one or more assisted cell (one or more SCell) can be called as in the upper one or more communities run of quenching frequency (or SCC).Basic frequency (or PCC) refers to and performs for UE the frequency (or CC) that initial connection establishment or connection re-establish process.PCell can refer to the community indicated during handoff procedure.Quenching frequency (or SCC) refers to the frequency (or CC) that can configure after performing RRC connection establishment, and can be used for providing other radio resource.PCell and SCell can be collectively referred to as Serving cell.Therefore, CA is not configured to it or do not support CA, the UE be in RRC_CONNECTED (RRC connection) state, only there is the Serving cell be only made up of PCell.Meanwhile, to its be configured with CA, the UE be in RRC_CONNECTED state, one or more Serving cell can be there is, and all Serving cells can comprise a PCell and one or more SCell.But, in future, Serving cell can be allowed to comprise multiple PCell.For CA, except the PCell of initial configuration in the connection establishment process after starting initial safe activation, network can also for supporting that the UE of CA configures one or more SCell.But even if UE supports CA, network also only can configure PCell for UE, and does not increase SCell.PCell can be called as main CC, grappling CC or main carrier, and SCell can be called as auxiliary CC or subcarrier.

In multi-carrier systems, BS can launch multiple data cell to UE in given one or more communities (or one or more CC), and UE can launch the ack/nack signal for multiple data cell in a subframe.UE can be assigned with one or more community (or DLCC) for receiving the PDSCH being used for DL data receiver.Can semi-statically be configured or reconfigure the community (or one or more DLCC) for UE by RRC signaling.And, can dynamically activate/forbid community (or one or more DLCC) for UE by L1/L2 (media interviews control (MAC)) control signal.Therefore, the maximum quantity of the ACK/NACK bit will launched by UE changes according to the community (or DLCC) that can be used for UE.That is, the maximum quantity of the ACK/NACK bit will launched by UE is configured by RRC/reconfigures, or is changed along with the DLCC activated (or one or more Serving cells of configuration) by L1/L2 signaling.

Figure 15 to describe in BS the concept that a MAC layer manages multiple carrier wave.Figure 16 to describe in UE the concept that a MAC layer manages multiple carrier wave.

See Figure 15 and Figure 16, a MAC layer manages one or more frequency carrier to perform transmitting and receiving.Because the frequency carrier managed by a MAC layer needs not to be continuous print, so resource management is more flexibly possible.In Figure 15 and 16, conveniently, a physical layer (PHY) represents a CC.At this, a PHY need not represent independently radio frequency (RF) device.Usually, one independently RF device represent a PHY but be not limited thereto.A RF device can comprise several PHY.

Figure 17 describes multiple MAC layer in BS and manages the concept of multiple carrier wave, and Figure 18 describes multiple MAC layer in UE manages the concept of multiple carrier wave.Figure 19 describes another concept that multiple MAC layer in BS manages multiple carrier wave, and Figure 20 describes another concept that multiple MAC layer in UE manages multiple carrier wave.

Except structure as shown in figures 15 and 16, multiple MAC layer instead of a MAC layer can control multiple CC, as shown in Figure 17 to 20.

As shown in FIG. 17 and 18, each MAC layer can control each carrier wave with man-to-man correspondence.As shown in Figure 19 and 20, each MAC layer can control each carrier wave about partial carrier wave with man-to-man correspondence, and a MAC layer can about the one or more carrier wave of other carrier Control.

The system being applicable to explanation is above the system of support carrier wave to N many carrier waves, and carrier wave can be continuous or discrete carrier wave, and has nothing to do with UL/DL.TDD system is configured to manage N number of carrier wave, and each carrier wave comprises DL and UL and launches, and FDD system is configured to use multiple carrier wave respectively in UL and DL.FDD system can support asymmetric CA, wherein, the quantity of the polymerization carrier wave in UL with DL and/or the bandwidth of carrier wave different.

If the quantity of the CC be polymerized in UL equals the quantity of the CC be polymerized in DL, then can configure CC and make all CC compatible with the CC used in conventional systems.But, do not get rid of from the present invention and do not support compatible CC.

For convenience of description, although providing explanation under the hypothesis of launching the PDSCH corresponding to PDCCH when launching PDCCH on DLCC#0 on DLCC#0, obviously, intersection carrier dispatching can be applied, making to launch PDSCH on the DLCC different from DLCC#0.

Figure 21 and 22 diagram is used for the PUCCH format 1a of ACK/NACK transmitting and the timeslot-level structure of 1b.

PUCCH format 1a when Figure 21 is shown in normal CP and 1b, and PUCCH format 1a when Figure 22 is shown in expansion CP and 1b.Identical control information is repeated on a timeslot basis in the subframe of PUCCH format 1a and 1b.The different cyclic shifts (CS) (frequency domain code) of perseverance zero auto-correlation (CG-CAZACC) sequence that UE is produced by computer and the different resource of orthogonal covering (OC) or orthogonal covering coding decoder (OCCc) (time domain extended coding decoder) launch ack/nack signal.OC comprises such as Walsh/DFT orthogonal code.If the quantity of CS is 6 and the quantity of OC is 3, then can based on individual antenna multiplexing 18 UE altogether in Same Physical Resource Block (PRB).Orthogonal sequence w0, w1, w2 and w3 is applied in any time domain (after FFT modulation) or in any frequency domain (before FFT modulation).The PUCCH format 1 of launching for SR is identical in timeslot-level structure with 1b with PUCCH format 1a, and different in modulation scheme.

(RRC) signaling can be controlled by radio resource and distribute the PUCCH resource be made up of CS, OC and PRB to UE, launch for SR and feed back for the ACK/NACK for semi-persistent scheduling (SPS).As described in reference to Figure 12, for the ACK/NACK feedback of the dynamic ack/NACK ACK/NACK of impermanent scheduling (or for) feedback or the PDCCH for instruction SPS release, the minimum CCE index of the PDCCH corresponding with PDSCH or PDCCH discharged for SPS can be used implicitly to distribute PUCCH resource to UE.

Figure 23 is shown in the scene of supporting to launch UCI in the wireless communication system of CA.For convenience of description, suppose in this illustration, UCI is ACK/NACK (A/N).But UCI can comprise control information, such as CSI (such as, CQI, PMI and RI) and scheduling request information (such as, SR), and do not limit.

The asymmetric CA of Figure 23 illustrative exemplary, wherein, 5 DLCC are linked to single ULCC.This asymmetric CA can be set from the viewpoint of launching UCI.That is, the DLCC-ULCC association for UCI can be set to and associates different from the DLCC-ULCC for data.Conveniently, if assuming that each DLCC can carry until two code words, and depend on the maximum quantity of the code word set by each CC (such as the quantity of the ACK/NACK of each CC, if BS is arranged until two code words for specific CC, even if specific PDCCH only uses a code word on this CC, ACK/NACK for this CC is set to 2, the maximum quantity of the code word namely on this CC), then at least two ULACK/NACK bits are needed for each DLCC.In this case, needs at least 10 ACK/NACK bits launch the ACK/NACK for the data received on 5 DLCC on single ULCC.If also indicate discontinuous transmitting (DTX) state for each DLCC, then need at least 12 bits (=5 ⁶=3125=11.61 bit) come to launch for ACK/NACK.Because can obtain in conventional PUCCH format 1a and 1b until two ACK/NACK bits, this structure can not launch the ACK/NACK information of increase.Although CA is given the example of the cause of the quantity increasing UCI, this situation also may owing to occurring in the existence of the quantitative increase of antenna and the backhaul subframe in TDD system and relay system.Be similar to ACK/NACK to launch, when launching the control information relevant to multiple DLCC on single ULCC, the amount of the control information that launch also increases.Such as, the transmitting of relevant to multiple DLCC CQI/PMI/RI information can increase UCI payload.

In fig 23, UL grappling CC (also referred to as the main CC of ULPCC or UL) is the CC launching PUCCH or UCI thereon, and can by community specifically/UE specifically determines.In addition, DTX state can be fed back by explicitly, or can be fed and make to share identical state with NACK.

Below, with reference to accompanying drawing, the method being used for the UCI effectively launching increase is proposed.Specifically, the new PUCCH format/signal processing operations/resource allocation methods of the UCI for launching increase is proposed.The new PUCCH format proposed by the present invention is called as CAPUCCH form or the PUCCH format 3 relative to the PUCCH format 2 of definition in traditional LTE version 8/9.The technical characteristic of the PUCCH format proposed easily can be applied to any physical channel (such as, PUSCH) that can transmit UCI in the same manner or in a similar manner.Such as, embodiments of the invention are applicable to the cycle PUSCH structure of emission control information periodically or PUSCH structure aperiodic of ground emission control aperiodic information.

By focusing on following situation, drawings and Examples of the present invention are described: use the UCI/RS symbolic construction of the PUCCH format 1/1a/1b of traditional LTE (normal CP) to be used as the subframe/timeslot-level UCI/RS symbolic construction applied to PUCCH format 3.But, conveniently, exemplarily define the subframe/timeslot-level UCI/RS symbolic construction of PUCCH format 3, and the invention is not restricted to such ad hoc structure.In PUCCH format 3 of the present invention, quantity and the position of UCI/RS symbol freely can be changed according to system.Such as, the RS symbolic construction of the PUCCH format 2/2a/2b of traditional LTE can be used to define PUCCH format 3 according to an embodiment of the invention.

PUCCH format 3 may be used for the UCI launching any type or size according to an embodiment of the invention.Such as, the information of such as HARQACK/NACK, CQI, PMI, RI and SR can be launched with PUCCH format 3 according to an embodiment of the invention.This information can have the payload of any size.For convenience of description, explanation below focuses on the transmitting of the ACK/NACK information of PUCCH format 3 according to the present invention.

Figure 24 to 27 illustrates PUCCH format structure and signal processing operations thereof for feeding back multiple ACK/NACK bit.Such as, when feeding back multiple ACK/NACK bit in multicarrier environment, PUCCH format can be used.Such PUCCH format can be called as PUCCH format 3, to be distinguished by the conventional inline of itself and PUCCH format 1 and 2.

Figure 24 to 27 illustrates the PUCCH format structure based on DFT.According to the PUCCH structure based on DFT, PUCCH by DFT precoding, and applies time domain OC in SC-FDMA level to it before transmission.Below, the PUCCH format based on DFT will be called PUCCH format 3.

Figure 24 illustrates the example arrangement of the PUCCH format 3 of the OC using spreading factor (SF) 4 (SF=4).See Figure 24, channel coding blocks to information bit a_0, a_1 ..., a_M-1 (such as, multiple ACK/NACK bit) chnnel coding, and produces coded-bit (or code word) b_0, b_1 ..., b_N-1.M is the size of information bit, and N is the size of coded-bit.This information bit comprises UCI, such as, for multiple ACK/NACK of the multiple data (or PDSCH) received on multiple DLCC.At this, combined coding information bit a_0, a_1 ..., a_M-1, and have nothing to do with the type/quantity/size of the UCI of configuration information bit.Such as, if information bit comprises the multiple ACK/NACK for multiple DLCC, then chnnel coding is performed for whole bit information, instead of chnnel coding is performed for each DLCC or ACK/NACK bit that each is independent.Single code word is produced by chnnel coding.Chnnel coding includes, but are not limited to repetition, simplex coding, Randt's Miller (RM) coding, perforation RM coding, stings tail convolutional encoding (TBCC), low-density checksum (LDPC) coding or turbo coding.Although not shown, consider order of modulation and stock number and rate-matched can be carried out to coded-bit.This rate-matched function can partly be covered in channel coding blocks, or realizes in independent functional block.Such as, channel coding blocks can obtain single code word by performing (32,0) RM coding about multiple control information, and can perform circular buffering rate-matched.

Modulator is by modulating-coding bit b_0, b_1 ..., and b_M-1 produces modulation symbol c_0, c_1 ..., c_L-1.L is the size of modulation symbol.The amplitude transmitted by change and phase place perform modulation scheme.Modulation scheme comprises such as n phase shift keying (n-PSK) and n quadrature amplitude modulation (QAM) (wherein, n is the integer of two or more).Specifically, modulation scheme comprises binary system PSK (BPSK), orthogonal PSK (QPSK), 8-PSK, QAM, 16-QAM or 64-QAM.

Modulation symbol c_0, c_1 ..., c_L-1 are divided into time slot by divider.Rank/pattern/scheme modulation symbol being divided into time slot is not limited to specific one.Such as, modulation symbol sequentially can be divided into time slot by divider from the first modulation symbol (localized approach).In this case, modulation symbol c_0, c_1 ..., c_L-1 can be assigned to time slot 0, and modulation symbol c_L/2, c_L/2+1 ..., c_L-1 can be assigned to time slot 1.When modulation symbol is divided into time slot, can interweave (arrangement) modulation symbol.Such as, the modulation symbol of even-numbered can be distributed to time slot 0, and the modulation symbol of odd-numbered can be distributed to time slot 1.Modulation treatment can be exchanged and divide process in order.

DFT precoder performs DFT precoding (such as, 12 DFT), to produce multicarrier waveform about the modulation symbol being divided into time slot.See Figure 24, the modulation symbol c_0 distributed to time slot 0, c_1 ..., c_L/2-1 are DFT symbol d_0, d_1 ..., d_L/2-1 by DFT precoding, and the modulation symbol c_L/2 distributed to time slot 1, c_L/2+1 ..., c_L-1 are DFT symbol d_L/2, d_L/2+1 ..., d_L-1 by DFT precoding.DFT precoding can be replaced with another kind of linear operation (such as, Walsh precoding).

Extension blocks is at the signal (in the time domain) of SC-FDMA symbol level expansion DFT precoding.Use extended code (sequence) to perform to expand in the time domain of SC-FDMA symbol level.Extended code comprises quasiorthogonal code and orthogonal code.Quasiorthogonal code includes, but are not limited to pseudo noise (PN) code.Orthogonal code includes, but are not limited to walsh code and DFT code.Although for convenience of description orthogonal code to be described as the typical case of extended code, orthogonal code can be replaced with quasiorthogonal code.The maximum of extended code size or SF is limited by the quantity of the SC-FDMA symbol of the transmitting for control information.Such as, if four SC-FDMA symbols are launched for control information in one time slot, then orthogonal code w0, w1, w2 and w3 of length 4 can be used in each time slot.SF represents the degree of expansion of control information, and can be relevant to the antenna multiplexed exponent number of multiplexing order or UE.SF can depend on system requirements and change into 1,2,3,4 ....Can between BS and UE predefine SF, or BS can by DCI or RRC signaling come to UE indicate SF.Such as, if perforation be used for control information SC-FDMA symbol in one to launch SRS, then the extended code with the SF (such as, SF=3 instead of SF=4) of reduction can be applied to the control information in the time slot of correspondence.

The signal produced from operation is above mapped to the subcarrier among PRB, and is converted into time-domain signal by IFFT.Add CP to time-domain signal, and held by RF and launch produced SC-FDMA symbol.

Each operation will be described under the hypothesis that ACK/NACK is launched for 5 DLCC in more detail.If each DLCC can launch two PDSCH, then the ACK/NACK bit for this PDSCH can be 12 bits, comprises DTX state.Under the hypothesis of the temporal extension of QPSK and SF=4, the size (after rate-matched) of encoding block can be 48 bits.Coded-bit is modulated to 24 QPSK symbols, and QPSK symbol is divided into two time slots, and each time slot comprises 12 QPSK symbols.12 QPSK symbols in each time slot are converted into 12 DFT symbols by 12 DFT.12 QPSK symbols in each time slot use the extended code of SF=4 to be extended to four SC-FDMA symbols in the time domain, and then mapped.Because at [2 bit x12 subcarrier x8SC-FDMA symbol] upper transmitting 12 bits, so encoding rate is 0.0625 (=12/192).If SF=4, then can multiplexing maximum four UE of each PRB.

Figure 25 illustrates the example arrangement of the PUCCH format 3 of the OC using SF=5.

Except the quantity of UCISC-FDMA symbol and RSSC-FDMA symbol and position, to perform basic signal processing operations with identical mode described in reference diagram 25.Can in the front end place application extension block in advance of DFT precoder.

In fig. 25, RS can use and those the identical structures used in LTE system.Such as, can cyclic shift basic sequence.The multiplexing capacity of data division is due to SF=5 but 5.But, by CS interval delta _shift ^pUCCHdetermine the multiplexing capacity of RS part.Such as, multiplexing capacity can be 12/ Δ _shift ^pUCCH.In this case, for wherein Δ _shift ^pUCCH=1, Δ _shift ^pUCCH=2 and Δ _shift ^pUCCHthe multiplexing capacity of the situation of=3 is 12,6 and 4 respectively.In fig. 25, although the multiplexing capacity of data division due to SF=5 but 5, RS part multiplexing capacity at Δ _shift ^pUCCHwhen be 4.Therefore, overall multiplexing capacity can be limited to the smaller 4 of these two values.

Figure 26 diagram can increase the example arrangement of the PUCCH format 3 of multiplexing capacity on timeslot-level.

Can by increasing overall multiplexing capacity to the SC-FDMA symbol level expansion described in RS application reference Figure 24 and 25.See Figure 26, cover (or the covering of DFT code) by applying Walsh in time slot and multiplexing capacity is doubled.Then, even if multiplexing capacity is at Δ _shift ^pUCCHwhen be also 8, prevent the multiplexing capacity of data division from reducing thus.In fig. 26, [y1y2]=[11], [y1y2]=[1-1] or its linear transformation (such as, [jj] [j – j], [1j] [1 – j] etc.) may be used for the OC of RS.

Figure 27 diagram can increase exemplary PUCCH format 3 structure of multiplexing capacity in sub-frame level.

When not applying timeslot-level frequency hopping, again multiplexing capacity is doubled by applying Walsh covering in units of time slot.As mentioned above, [x1x2]=[11], [1-1] or its conversion can be used as OC.

As a reference, the process of PUCCH format 3 operates the order be not limited to shown in Figure 24 to 27.

channel assignment

Channel assignment refers to the expression/transmitting of the customizing messages undertaken by selecting specific resources from multiple resource.Common Channel assignment is the scheme of being launched customizing messages by the combination of resource and constellation.

At this, allocated resource can be carried out by physical time-frequency resource and/or sequence resources (such as, CS value).Such as, in LTE version 8PUCCH form 1/1a/1b, specific resources can be selected by the combination of OC, CS and physical resource unit (PRU).Can suppose, be distinguished the multiple resources performing Channel assignment thereon by the combination of kind of the resource of three above.Such as, the channel selecting method shown in table 3 below can be used in.

[table 3]

Superincumbent table 3 neutralizes in the following description, be expressed as a, b, c ... value can represent the constellation value caused by the modulation (such as, BPSK, QPSK etc.) in channel Ch-x (x=1,2,3 ...).Or, be expressed as a, b, c ... value can be the sequence be assigned with or the code be assigned with is multiplexing, the value of scrambling or covering, instead of constellation value.Therefore, about Ch-x be expressed as a, b, c ... value can be the value that can distinguish betwixt, and do not limit the method for distinguishing between these values.Especially, in the following description, for convenience of description, about Ch-x be expressed as a, b, c ... value be called as modulation value.

In addition, be expressed as a, b, c ... value can be predetermined particular value, instead of 0.Such as, a can be '+1 ', and b can be '-1 '.

In the example of table 3, even if launch same value, also can depend on which channel launches different information (that is, ACK or NACK) for launching.Such as, for ACK launch, transmitted value a in the RS part of resource 1 (that is, channel 1), and in the data division of resource 1 transmitted value b.NACK is launched, in the RS part of resource 2 (that is, channel 2), launches a, and launch b in the data division of resource 2.By this way, the method for launching different information for being determined by which resource to transmit can be called as Channel assignment.

In table 3, show the simple examples not using complicated constellation mapping, but other constellation mapping can be used for launching more information.Table 4 illustrates the example of the constellation mapping distinguished (such as, BPSK) of use two type.

[table 4]

In superincumbent table 4, a, b and c can be the particular values except 0.Note, preferably, b and c on constellation away from each other.Such as, a can be used as '+1 ', and b and c can be used as '+1 ' and '-1 ' respectively or be used as respectively '-1 ' and '+1 '.In the example of table 4, ACK/ACK is transmitted in the value of launching in resource 1 (channel 1) and being modulated to b, and ACK/NACK is transmitted in the value of launching in resource 1 (channel 1) and being modulated to c.In addition, NACK/ACK is transmitted in the value of launching in resource 2 (channel 2) and being modulated to b, and NACK/NACK is transmitted in the value of launching in resource 2 (channel 2) and being modulated to c.

Define in table 5,6 and 7 below use in traditional LTE version 8/9, in TDD for the mapping relations of Channel assignment that ACK/NACK launches.In LTE version 8/9, TDDACK/NACK is multiplexing can have the implication identical with TDDACK/NACK Channel assignment, but they have different implications in following multicarrier back-up system (such as, LTE-A or LTE version 10).

In table 5 below, 6 and 7, in a tdd system, DL relevant episode index K:{k can be passed through ₀, k ₁... k _m-1(as in the table 12 that describes later define) carry out determined value M.Such as, if M=2, then two PUCCH resource in table 5 with and QPSK constellation in each PUCCH resource ' b (0), b (1) ' may be used for the ACK/NACK information of transmitting two type, comprise space binding (that is, the ACK/NACK for multiple code word bundlees).

Specifically, UE uses PUCCH format 1b in ACK/NACK resource in subframe n upper transmitting bit ' b (0), b (1) '.Can by according to below table 5,6 and 7 Channel assignment come generated value ' b (0), b (1) ' and ACK/NACK resource table 5,6 and 7 illustrates the multiplexing transmitting of ACK/NACK as M=2, M=3 and M=4 respectively.If ' b (0), b (1) ' are mapped to NACK/ACK, then UE does not launch ACK/NACK response in subframe n.

[table 5]

[table 6]

[table 7]

In table 5,6 and 7, HARQ-ACK (i) instruction is used for the HARQACK/NACK/DTX result of i-th (0≤i≤3) data cell.DTX represents not to be launched and also the data cell corresponding with HARQ-ACK (i) do not detected for the data cell of the HARQ-ACK (i) of correspondence or UE.In this specification, HARQ-ACK is used interchangeably with ACK/NACK.Maximum four PUCCH resource (that is, n can be taken for each data cell ⁽¹⁾ _{pUCCH, 0}to n ⁽¹⁾ _{pUCCH, 3}).Multiplexing ack/nack signal is launched by the PUCCH resource selected from the PUCCH resource taken.In table 5,6 and 7, n ⁽¹⁾ _{pUCCH, x}instruction is used for the PUCCH resource that actual ACK/NACK launches, and ' two bits that b (0) b (1) ' instruction is launched by selected PUCCH resource, it is used QPSK to modulate.Such as, four data cells if UE has successfully decoded as in table 7, then UE is by being connected to n ⁽¹⁾ _{pUCCH, 1}pUCCH resource come to BS launch (1,1).Because the combination of PUCCH resource and QPSK symbol can not represent all obtainable ACK/NACK, so except in some cases, NACK and DTX is coupled (being expressed as NACK/DTX).

Meanwhile, in LTE-A (or the LTE version 10) system that the present invention is suitable for, have no particular limits about the Channel assignment mapping relations for applying channel selecting method.Such as, the Channel assignment mapping relations for launching ACK/NACK information as shown in table 8 to 10 can be defined.Table 8 defines the mapping relations for 2 bit ACK/NACK, and table 9 defines the mapping relations for 3 bit ACK/NACK, and table 10 defines the mapping relations for 4 bit ACK/NACK.

[table 8]

[table 9]

[table 10]

Or, the channel mapping relation for 1 bit to 4 bit ACK/NACK as shown in table 11 can be defined.In the example of table 11, b0 can be generated and launch for 1 bit ACK/nack message, b0 and b1 can be generated and launch for 2 bit ACK/nack message, b0, b1 and b2 can be generated and launch for 3 bit ACK/nack message, and b0, b1, b2 and b3 can be generated and launch for 4 bit ACK/nack message.

[table 11]

for the ULACK/NACK that DL launches in multicarrier back-up system

In multicarrier system or CA back-up system, DL resource can be defined as DLCC, and UL resource can be defined as ULCC.In addition, the combination of DL resource and UL resource can be called as community.If configure DLCC and ULCC asymmetrically, then community only can refer to DLCC (or ULCC).Such as, if configure specific UE with a Serving cell, then there is a DLCC and ULCC.But, if configure specific UE with two or more Serving cell, then there is quantitatively equal with community DLCC and be quantitatively equal to or less than the ULCC of DLCC.When configuring particular UE with multiple Serving cell, can support that the quantity of wherein ULCC is greater than the multicarrier environment of the quantity of DLCC.

Can by indicating the association between the carrier frequency (centre frequency of community) of DL and UL resource in the system information of DL transmitted on resources.Such as, the combination of DL resource and UL resource can be configured by the association defined by SIB2.

According to definition above, CA can refer to the set of two or more communities with different carrier frequencies.That is, the situation wherein configuring specific UE with two or more Serving cells with different carrier frequencies can be called as CA environment.For the UE supporting CA, one or more SCell can be polymerized to support the bandwidth increased with PCell.

In this case, Serving cell can be PCell or SCell.For the UE be in RRC_CONNECTED state not supporting CA, only there is the Serving cell comprising PCell.Meanwhile, for the UE be in RRC_CONNECTED state being configured with CA, Serving cell refers to the set of the one or more communities comprising PCell and SCell.

PCell is the center cell of the control related communication in the Serving cell configured in CA environment.PCell is the community being indicated in initial connection establishment process, connection reconstruction process or handoff procedure by UE or used.UE can only receive and launch PUCCH on its PCell.In addition, UE can perform monitor procedure, obtains and change for the system information only on PCell.CA is supported that UE, BS can use the RRCConnectionReconfiguration message comprising mobilityControlInfo to change by means of only handoff procedure.

Next, SCell refers to the community in the Serving cell configured in CA environment except PCell.There is not PUCCH in SCell.If add SCell, then BS can by dedicated signaling to supporting that the UE of CA provides all system informations relevant to the operation on the SCell of RRC_CONNECTED state.For SCell, the change in system information can be performed by the release of the SCell via a RRCConnectionReconfiguration message and interpolation.BS can launch the dedicated signaling with the parameter different from the parameter that the broadcast on SCell comprises to UE.After initial safe activation, BS can also configure one or more SCell for UE except PCell (as the community of Serving cell configuration during connection establishment process).PCell may be used for providing safety input and higher hierarchy system information, and SCell may be used for providing other DL resource, and provides UL resource as necessary.BS can be used the RRCConnectionReconfiguration message that comprises or do not comprise mobilityControlInfo to be connected by RRC and reconfigure process and add independently, eliminate or correct SCell.

In CA environment, PhyCellId, SCellIndex and ServCellIndex can be defined as RRC relevant parameter/information element (IE).PhyCellId can have the integer of scope from 0 to 503, and can be used as the physical layer identifier of community.SCellIndex can have the integer of scope from 1 to 7, and can be used as the identifier of SCell.ServCellIndex can have the integer of scope from 0 to 7, and can be used as the identifier of Serving cell (PCell or SCell).The ServCellIndex with value 0 can be applied to PCell, and for SCell, can apply SCellIndex.That is, the community with minimum (or minimum) cell index in ServCellIndex can be defined as PCell.

In a word, the multiple carrier waves in CA can be divided into PCell and SCell as UE special parameter.Specific UE can have the Serving cell of one or more configuration.If there is the Serving cell of multiple configuration, then one of Serving cell is PCell, and other communities are SCell.If UE has the Serving cell of multiple configuration in TDD, then indicate which UL subframe for launch for the ACK/NACK of the PDSCH launched in specific DL subframe UL-DL configuration can be identical in all cells.

In addition, UE can launch UCI and HARQACK/NACK that measure from one or more CC, such as CSI (comprising CQI, RI, PMI etc.) to BS in a predetermined C C.Such as, if need multiple ACK/NACK to feed back, then UE can collect and feed back (such as from the ACK/NACK of PCellDLCC and one or more SCellDLCC reception, ACK/NACK multiplexing or ACK/NACK binding), and can use a PUCCH launch to BS in the ULCC of PCell collected by ACK/NACK feedback.

In the present invention, when launching by a PUCCH the multiple ack/nack signal launched for multiple DL, the unit (one or more subframe and/or one or more carrier wave) forming multiple DL transmitting is called as bundled window.That is, time domain binding refers to the ack/nack signal launched for DL be bundled in multiple subframe.The binding of CC territory refers to the ack/nack signal launched for DL be bundled in multiple CC.Time domain/CC territory binding refers to the ack/nack signal launched for DL be bundled in multiple subframe and multiple CC.Although ACK/NACK binding can be performed by logic and operation, the present invention is not limited thereto, and other computings of such as logic OR can be used.

In addition, the unit for using logical AND (or logic OR) computing to come the binding of actual execution time domain and/or the binding of CC territory can be called as actual bundled window.That is, one or more actual bundled window can be there is in a bundled window.In other words, the size of bundled window is equal to or greater than the size of actual bundled window.At this, space binding (that is, the ACK/NACK for multiple code word bundlees) of the multiple ACK/NACK bits for launching for a DL can be applied, and have nothing to do with bundled window or actual bundled window.

Be described in now example that define in 3GPPLTE system, that need the ACK/NACK that DL is launched.At this, when launching ACK/NACK in subframe n, ACK/NACK launches relevant to the DL in subframe n-k.

In a tdd system, about the relation between subframe n and subframe n-k, as shown in Table 12, DL relevant episode index K:{k can be provided for each UL-DL configuration of table 1 ₀, k ₁... k _m-1.

[table 12]

In fdd, M always 1, and K always meets { k ₀}={ 4}.When launching the ACK/NACK launched for the DL in subframe n-k in subframe n, DL in subframe n-k launch can correspond to below one or more of three kinds of situations.

Situation 1 is when needing to feed back for the ACK/NACK of the one or more PDSCH indicated by the one or more PUCCH detected in one or more subframe n-k.At this, k ∈ K, and K changes according to subframe index n and UL-DL configuration, and comprise M element { k ₀, k ₁... k _m-1.Table 12 below shows K:{k ₀, k ₁... k _m-1.Situation 1 relates to one or more PDSCH that the common ACK/NACK of requirement feeds back.In the following description, situation 1 is called as ' for the ACK/NACK ' of PDSCH or ' for the ACK/NACK ' of PDSCH with PDCCH.

Situation 2 is when needing the ACK/NACK feedback for one or more PDCCH of the DLSPS release of instruction in one or more subframe n-k.At this, k ∈ K, and K represents the index identical with the explanation provided in situation 1.The ACK/NACK of situation 2 represents that the ACK/NACK for the one or more PDCCH discharged for SPS feeds back.Meanwhile, when performing the ACK/NACK feedback for DLSPS release, do not perform the ACK/NACK feedback of one or more PDCCH that instruction SPS is activated.In the following description, situation 2 is called as ' for the ACK/NACK ' of DLSPS release PDCCH.

Situation 3 is when needing the ACK/NACK feedback for the transmitting of one or more PDSCH, one or more PDCCH of the correspondence wherein do not detected in one or more subframe.At this, k ∈ K, and K represents the index identical with the explanation provided in situation 1.Situation 3 about one or more PDSCH of neither one or multiple PDCCH, and represents that the ACK/NACK for one or more SPSPDSCH feeds back.In the following description, situation 3 is called as ' for the ACK/NACK ' of DLSPSPDSCH.

In the following description, there is the PDSCH of corresponding PDCCH, for the PDSCH of DLSPS release and the DL transmitting that do not have the PDSCH of corresponding PDCCH to be collectively referred to as to need ACK/NACK to launch.

Example of the present invention when the ACK/NACK for DL transmitting is above applied to multicarrier system will be described in detail below.

In order to the convenience illustrated, by under hypothesis below, example of the present invention is described.But embodiments of the invention are not limited to hypothesis below.

(1) PCell and one or more SCell can be there is.

(2) PDSCH with corresponding PDCCH can be there is on PCell and one or more SCell.

(3) PDCCH of instruction DLSPS release only can be there is on PCell.

(4) PDSCH (=SPSPDSCH) not having corresponding PDCCH can only be there is on PCell.

(5) cross scheduling from PCell to one or more SCell can be supported.

(6) cross scheduling from one or more SCell to PCell is not supported.

(7) cross scheduling of from one or more SCell to another SCell (or other SCell) can be supported.

In explanation of the present invention, time domain binding and/or CC territory bundle presentation logic and computing.But, time domain binding and/or the binding of CC territory can be performed by the additive method of such as logic OR computing etc.That is, time domain binding or the binding of CC territory refer to in the ACK/NACK response using single PUCCH format, the multiple ACK/NACK in multiple subframe or CC are expressed as the method for the ACK/NACK information with less bit.In other words, time domain binding or CC territory bundle any means referred to for by the ACK/NACK information representation of M-bit being N bit (M >=N).

In the system that multicarrier and/or TDD are applied to, can by using the Channel assignment of PUCCH format 1a/1b, PUCCH format 3 or using the Channel assignment of PUCCH format 3 to launch multiple ACK/NACK bit.For the PUCCH resource index for PUCCH format, can use that implicit expression maps, the combination of explicit mapping or implicit expression and explicit mapping.Implicit expression maps and the minimum CCE index for the PDCCH based on correspondence can be used to draw the method for PUCCH resource index.Explicit mapping can use the method being indicated by the ACK/NACK resource indicator (ARI) in PDCCH or draw being configured the predetermined PUCCH resource index concentrated by RRC.

Related to the present inventionly, when format (such as, the PUCCH format 3 with reference to Figure 24 to 27 describes) for launching multiple ACK/NACK bit, substantially distributing based on explicit resource and performing the Resourse Distribute of PUCCH format 3.

Specifically, the UE being configured to PUCCH format 3 can be used for the orthogonal resource of this form by explicitly (such as, by RRC signaling) assignment.In addition, final PUCCH resource can be determined by the ARI value in the PDCCH of the PDSCH for launching on SCell being configured by RRC in predetermined orthogonal resource.In this case, ARI can be used as the skew of PUCCH resource value transmitted based on explicitly signal, or may be used for indicating which that will be used in that one or more PUCCH resource concentrates.

In order to comprise ARI information in PDCCH, the field can considering to reuse existing PDCCH carrys out the method for ARI object.PDCCH can comprise transmitting power and control (TPC) field.The original object of TPC field is the transmitting power of control PUCCH and/or PUSCH, and can be made up of 2 bits.

As mentioned above, when only launching ARI on SCell, the TPC field in the PDCCH on SCell can be used as ARI again.Meanwhile, the transmitting power that the TPC field in the PDCCH on PCell may be used for PUCCH controls.

In LTE version 10 system, because the PDCCH of the PDSCH for dispatching PCell can not be received (namely on SCell, do not allow the intersection carrier dispatching carrying out the PDSCH of PCell from the PDCCH of SCell), so the implication that UE only receives PDSCH on PCell can be equal to the implication that UE only receives PDCCH on PCell.

The explicit ACK/NACK Resourse Distribute by RRC signal deployment can be performed as follows.

First, PDCCH (that is, for dispatch the PDCCH of the PDSCH) resource that can comprise for from one or more RRC configure corresponding with PDSCH on SCell draws the information (such as, ARI) of specific PUCCH resource.

Next, if do not receive the PDCCH corresponding with PDSCH and receive PDSCH on SCell on PCell, then one of situation below can be applied.First, the PUCCH resource (that is, PUCCH format 1a/1b) of definition in LTE version 8 can be used in.The second, the PDCCH corresponding with the PDSCH resource that can comprise for configuring from one or more RRC on PCell draws the information (such as, ARI) of specific PUCCH resource.

UE can suppose that all PDCCHs corresponding with PDSCH on SCell have identical ARI.

By this way, when by ARI information definition for only launch on SCell time, if UE only receives the one or more PDSCH (or only receiving one or more PDCCH on PCell) for PCell in multicarrier and/or TDD system, then because UE can not know the ARI information of launching from SCell, then can not determine the final resource index of the PUCCH format (PUCCH format 3) for being used by UE.

Even if determine the method for the final resource index of PUCCH format when being designed to one or more PDSCH (or only the receiving one or more PDCCH on PCell) that the present invention proposes for only receiving as UE for PCell of the problem above that solves.

In various example of the present invention, for convenience of description, the situation (or wherein UE only receives the situation of one or more PDCCH on PCell) that wherein UE only receives the one or more PDSCH for PCell is called for short ' only PCell receives '.At this, the reception about UE defines only PCell and receives.If the present invention is applied to multicarrier environment, then UE can have the community of a configuration or the community of multiple configuration.If UE has the community of a configuration, Ze Gai community can be PCell, and if UE has the community of multiple configuration, Ze Gai community can be made up of a PCell and one or more SCell.The present invention can be applied to one of both of these case or two kinds of both situations.That is, only PCell reception condition can be applied to CA environment and non-CA environment.

And, as mentioned above, can by new PUCCH format, that is, PUCCH format 3 is launched for the ACK/NACK launched for the DL received by multiple DL subframe in a tdd system, even if when UE comprises the community of a configuration.When UE comprises the community of multiple configuration, also PUCCH format 3 can be used in FDD or TDD system.That is, PUCCH format 3 can be used in CA system or non-CATDD system.

And in various example of the present invention, the candidate resource collection for PUCCH format 3 can be configured by RRC.The value can passing through ARI information (reusing of the TPC field of PDCCH can be expressed as) determine or from this ARI information worth go out specific PUCCH resource PUCCH resource Candidate Set.In brief, the ARI comprised from PDCCH in the resource candidate of RRC configuration draws PUCCH format 3 resource that will be used by UE.When the TPC field (2 bit size) as described above by the PDCCH on SCell reuse express ARI time, ARI has the size of X bit, and X can be defined as 2.Such as, 2 bit A RI can be used express a resource of four PUCCH resource candidates.

In order to the convenience of explanation be associated with the application of PUCCH format 3, under the individual antenna by a needs orthogonal resource performs the hypothesis of launching, the present invention is described.But, obviously, the present invention is not limited thereto, even and if when applying the multiple antennas transmit diversity scheme of such as orthogonal space resource transmit diversity (SORTD) to PUCCH format 3, principle of the present invention is also suitable in an identical manner.

Now, based on explanation above, the of the present invention exemplary hypothesis for PUCCH format 3 Resourse Distribute is described.

Resource for PUCCH format 3 can be expressed as and can be expressed as four orthogonal resource candidates of PUCCH format 3 with any UE can be assigned four such orthogonal resources by RRC signaling.RRC signaling can be such as four independent RRC signals.A set being made up of four orthogonal resources can be notified to UE by a RRC signaling the UE being assigned four PUCCH resource candidates can finally determine a PUCCH resource in four PUCCH resource candidates based on the value indicated by the ARI received in addition

Table 13 below illustrates the example resource allocation for PUCCH format 3 in single-antenna transmission.

[table 13]

Below, various embodiment of the present invention is described in detail based on explanation above.

embodiment 1

The present embodiment 1 relate to only PCell reception condition (that is, only receive for one or more PDSCH of PCell situation or on PCell, only receive the situation of one or more PDCCH) under use the method for predefined Resourse Distribute.

When only PCell receives, the resource index of PUCCH format 3 can be determined.That is, when non-only PCell receives, UE can draw PUCCH resource index from the ARI received at SCell, and in only PCell receives, UE can use predetermined PUCCH resource index.

Specifically, new index can be made a reservation for, make UE can determine PUCCH format 3 resource that will use when only PCell receives.New index can have the implication identical with the ARI on SCell.In other words, this index may be used for indicating by any one of the resource Candidate Set of RRC signal deployment.Index can be limited with the form of predefine rule (or particular value), this predefine rule (or particular value) is used to indicate the resource (such as, first resource or last resource) of the particular sorted in resource Candidate Set.

Such as, under only PCell reception condition, can determine that the index of PUCCH format 3 resource can be defined as system specific values.Or this index can be configured to eNB particular value or UE particular value by RRC.

Figure 28 is the flow chart being shown in the predefined Resourse Distribute determined for PUCCH resource when only PCell receives.

In step S2810, UE can configure the PUCCH resource Candidate Set that (such as, RRC signaling) receives four resources comprised for PUCCH format 3 by higher level

{n_{P U C C H, 0}^{(3)}, n_{P U C C H, 1}^{(3)}, n_{P U C C H, 2}^{(3)}, n_{P U C C H, 3}^{(3)}} .

In step S2820, when PUCCH format 3 is launched for ACK/NACK, UE can determine that whether situation is only PCell reception condition.If whether (that is, non-only PCell reception condition) determination result in step S2820, then performs step S2830, and if for being (that is, only PCell reception condition), then perform step S2840.

In step S2830, UE can use and come to calculate/select a PUCCH resource (that is, a resource index) that will be used by it from four PUCCH resource candidates by the indicated ARI that reuses of the TPC field in one or more PDCCH of SCell.

Meanwhile, because do not receive PDCCH in step S2840 on SCell, so UE can select a PUCCH resource according to predefine rule (or predefine index) from four PUCCH resource candidates.In the examples shown of Figure 28, predefine rule is in PUCCH resource Candidate Set, select last PUCCH resource index.That is, in step S2940, UE can calculate/select

After step S2830 or step S2840, UE can use with resource corresponding to the index that calculates/select launch ACK/NACK information by PUCCH format 3.

embodiment 2

The present embodiment 2 relates to a kind of method of the PUCCH resource distribution for predetermined other resource index and in the resource index using this other comes for receiving at only PCell situation (that is, only receiving the situation being used for one or more PDSCH of PCell or the situation only receiving one or more PDCCH on PCell).

When only PCell receives, can the other resource index of predetermined PUCCH format 3.That is, UE can draw PUCCH resource index when non-only PCell receives from the ARI received at SCell, and UE can use predetermined other PUCCH resource index when only PCell receives.Predetermined index in superincumbent embodiment 1 is the predetermined index of one of PUCCH resource candidate for configuring for UE, and embodiment 2 does not coexist with embodiment 1: the predetermined other resource index be separated with the PUCCH resource candidate configured for UE.

Such as, according to this embodiment, if use 2 bit A RI and define the set of the resource candidate of four RRC configuration, then can transmit an other resource candidate by RRC signaling to UE signal.Then, the resource Candidate Set of RRC configuration comprises 5 PUCCH resource indexes, and one of them predetermined resource index (such as, last index) can be defined as only using under only PCell reception condition.Or, can define with four PUCCH resource candidates the resource candidate received for only PCell discretely.In two kinds of both situations above, can distribute only for the reservation of resource index (that is, not by resource index that the ARI on SCell specifies) of only PCell reception condition to UE.At this, although preferably, the resource candidate not by other for of being used for that only PCell receives is overlapping with the resource candidate that four existing RRC configure, and can allow overlap in some cases.

Figure 29 is the flow chart being shown in the other predefine Resourse Distribute determined for PUCCH resource under only PCell reception condition.

In step S2910, UE can configure the PUCCH resource Candidate Set that (such as, RRC signaling) receives four resources comprised for PUCCH format 3 by higher level

{n_{P U C C H, 0}^{(3)}, n_{P U C C H, 1}^{(3)}, n_{P U C C H, 2}^{(3)}, n_{P U C C H, 3}^{(3)}, n_{P U C C H, 4}^{(3)}} .

In step S2920, when PUCCH format 3 is launched for ACK/NACK, UE can determine that whether situation is only PCell reception condition.If whether (that is, non-only PCell reception condition) determination result in step S2920, then performs step S2830, and if for being (that is, only PCell reception condition), then perform step S2940.

In step S2930, from 5 PUCCH resource candidates regular four predetermined PUCCH resource candidates (such as, four low index PUCCH resource according to the rules with ) in, UE can use and reuse indicated ARI from four PUCCH resource candidates by the TPC field in one or more PDCCH of SCell calculate/select a PUCCH resource that will be used by it.

Meanwhile, because do not receive PDCCH in step S2940 on SCell, so UE can select a PUCCH resource according to predefine rule.This predefined rule can be for selecting last resource from the PUCCH resource candidate of 5 RRC configurations rule.Can limit and not determine the rule of four in 5 PUCCH resource candidates by being used in step S2930 and being used for determining that the rule of in 5 PUCCH resource candidates is overlapping in step S2940.But, in some cases, can make to select overlapping resource candidate by restrictive rule.

After step S2930 or step S2940, UE can use with resource corresponding to the index that calculates/select launch ACK/NACK information by PUCCH format 3.

embodiment 3

Embodiment 3 relates to the method using downlink allocation index (DAI) to come for the PUCCH resource distribution under only PCell reception condition (that is, only receiving the situation being used for one or more PDSCH of PCell or the situation only receiving one or more PDCCH on PCell).

In above-described embodiment 1 and 2, describe for drawing the method not using other physical layer signaling (such as, PDCCH signaling) in only PCell receives for the resource index of PUCCH format 3.Embodiment 3 relates to a kind of method that can perform the information of the function of ARI defining and be used in the physical layer signal that PCell receives, although can not receive ARI on SCell resembling in existing scheme, owing to there is not PDCCH on SCell.Specifically, this embodiment relates under only PCell reception condition, to be used in DAI information that PDCCH the comprises method as ARI information.

Define the DAI field in PDCCH in a tdd system, and assign DAI about DL distribution (or PDSCH scheduling).When UE launches the ack/nack signal for multiple DL assignment (PDSCH) in a UL subframe, can draw the information of the quantity about DL assignment (PDSCH) from DAI, assigning (PDSCH) for this DL will launch ack/nack signal.Such as, when UE launches ack/nack signal (the using ACK/NACK binding) for multiple DL assignment (PDSCH) to BS, wherein UE fails the situation of the part receiving (that is, losing) multiple PDCCH and may occur.Now, because UE can not know the situation transmitting the PDSCH corresponding with the PDCCH taken defeat to it, so mistake may be there is in ACK/NACK produces.DAI can be used to solve such problem.In existing TDD system, such as, when a UL subframe corresponds to N number of DL subframe wherein, if sequentially assign (namely to the PDCCH launched in N number of DL subframe, sequentially count) DAI, then UE can be known whether by the DAI information in PDCCH and correctly receive previous PDCCH.

In this embodiment, considering that the DAI in the PDCCH when using PUCCH format 3 at PCell is not used in the situation of original object, proposing the ARI being again used as by DAI and determining that PUCCH resource assigns.Specifically, even if use PUCCH format 3 in a tdd system, in the operation as the full multiplexer mode of ACK/NACK, do not need DAI information yet, in the full multiplexer mode of ACK/NACK, do not perform time domain binding or CC territory (or frequency domain) binding.Therefore, DAI field can be used as the ARI of only PCell reception again.

Figure 30 is the flow chart being shown in example DAI field being used as under only PCell reception condition the ARI that PUCCH resource is determined.

In step S3010, UE can configure the PUCCH resource Candidate Set that (such as, RRC signaling) receives four resources comprised for PUCCH format 3 by higher level

{n_{P U C C H, 0}^{(3)}, n_{P U C C H, 1}^{(3)}, n_{P U C C H, 2}^{(3)}, n_{P U C C H, 3}^{(3)}} .

In step S3020, when PUCCH format 3 is launched for ACK/NACK, UE can determine that whether situation is only PCell reception condition.If whether (that is, non-only PCell reception condition) determination result in step S3020, then performs step S3030, and if for being (that is, only PCell reception condition), then perform step S3040.

In step S3030, UE can use and calculate/select a PUCCH resource (that is, a resource index) that will be used by it from four PUCCH resource candidates by the indicated ARI that reuses of the TPC field in one or more PDCCH of SCell.

Simultaneously, in step S3040, because do not receive PDCCH on SCell, so UE can use carry out by the indicated ARI that reuses of the DAI field in the PDCCH of PCell the PUCCH resource (that is, a resource index) that selection will be used by it from four PUCCH resource candidates.

After step S3030 or step S3040, UE can use with resource corresponding to the index that calculates/select launch ACK/NACK information by PUCCH format.

embodiment 3-1

Embodiment 3-1 relates to bundling the example applying identical ARI value in subframe under only PCell reception condition (that is, only receiving for one or more PDSCH of PCell or only receive the situation of one or more PDCCH on PCell).

The terms bundled subframe (or bundled window) used in explanation of the present invention represents the unit be made up of DL subframe when being launched the ACK/NACK response for the DL subframe in bundled window by a ULPUCCH, instead of in time domain or CC territory (or frequency domain), in fact perform the unit of binding.

Such as, in LTE version 8TDD system, as superincumbent table 12 (shows DL relevant episode index K:{k ₀, k ₁... k _m-1) shown in, give the definition about using which previous one or more DL subframe (subframe n-k) to launch the ACK/NACK response for the DL transmitting in specific UL subframe (subframe n).Describe in binding subframe in the example by table 12, when launching the ACK/NACK response of launching for the DL in one or more specific DL subframe in specific UL subframe, the one or more specific DL subframe is called as binding subframe.Such as, in UL-DL configuration 4, the binding subframe for UL subframe 2 is DL subframe 12,8,7 and 11, and is DL subframes 6,5,4 and 7 for the binding subframe of UL subframe 3.

If use PUCCH format 3 in TDD, then can launch as described above by a ULPUCCH ACK/NACK response that the DL in multiple DL subframe is launched.At this, when one or more PDCCH being detected according to embodiment 3 in multiple DL subframe under only PCell reception condition, if the ARI indicated by corresponding PDCCH (or DAI) value is different, then do not know which ARI value is for calculating/selecting PUCCH resource.

In order to prevent this problem, the ARI value (that is, the value of DAI field) of the PDCCH launched on PCell in binding subframe should be remained in the same manner.

embodiment 3-2

Embodiment 3-2 relates to the example applying identical ARI value in the CC of binding.

The terms bundled subframe (or bundled window) that uses in explanation of the present invention represent when the ACK/NACK response of being launched by a ULPUCCH for the DLCC in bundled window with binding in the presence/absence of the unit be made up of DLCC time irrelevant, instead of in time domain or CC territory (or frequency domain), in fact perform the unit bundled.Such as, when apply ACK/NACK complete multiplexing time, the CC of binding can have the implication identical with the quantity of the CC configured for UE.

If use PUCCH format 3 in TDD or FDD system, then can occur as mentioned above wherein launching by ULPUCCH the situation that the ACK/NACK for multiple DLCC responds.At this, the implication of ' ACK/NACK launched for multiple DLCC responds ' can indicate exists DL transmitting in PCell and one or more SCell.Now, if the ARI value in the PDCCH of PCell is different from the ARI value in the PDCCH of SCell, then unclear use which ARI value calculate/select PUCCH resource.

Therefore, in order to prevent problem above, should remain in the same manner on PCell for the value of the field (DAI field) of ARI object and on SCell for the value of the field (TPC field) of ARI object.

embodiment 3-3

Embodiment 3-3 relates to the example applying identical ARI value in binding CC and subframe.

When considering embodiment 3-1 and 3-2 (such as, when multiple CC and multiple subframe are binding unit), if the ARI value in corresponding community or corresponding subframe is different, then calculating/the selection of PUCCH resource may be unclear.Therefore, except remain on PCell and SCell ARI value in PDCCH equal except, the ARI value remained in the PDCCH in multiple subframe is equal.

embodiment 4

Embodiment 4 relates to a kind of method that the TPC of use field is come for the PUCCH resource distribution under only PCell reception condition (that is, only receiving the situation being used for one or more PDSCH of PCell or the situation only receiving one or more PDCCH on PCell).Embodiment 4 can be applied to wherein application or not apply two kinds of entirely multiplexing situations of ACK/NACK.Embodiment 4 also can be applied to wherein application or application space binding (ACK/NACK for multiple code word bundlees) two kinds of situations.

In superincumbent embodiment 3, describe the resource index for even determining PUCCH resource (such as, the resource of PUCCH format 3) in only PCell receives and do not used the method for other physical layer signaling.Embodiment 3 relates to the use DAI when DAI is not used as original applications (DL being distributed to the purposes of the index that (or PDSCH scheduling) sequentially assigns) and carrys out the example for ARI object.Therefore, when using PUCCH format 3 in a tdd system, if support time domain binding or CC territory (or frequency domain) binding, then DAI informational needs is used for original object, to produce correct ACK/NACK information.

Therefore, in example 4, under only PCell reception condition, DAI is not used in other objects.The present embodiment 4 proposes a kind of method TPC field in one or more PDCCH on PCell being used as again ARI under only PCell reception condition.

(that is, SCell exists PDCCH to launch) under non-only PCell reception condition, as mentioned above, the TPC field on SCell is reused for ARI.But, under only PCell reception condition, because there is no the transmitting of TPC field on SCell, so the new method for launching correct ACK/NACK must be defined.

According to embodiment 4, under only PCell reception condition, TPC field in the one or more specific PDCCH that PCell determines according to pre-defined rule may be used for original transmitting power and controls object, and the TPC field of one or more other PDCCH may be used for ARI object.The TPC field of the one or more specific PDCCH determined according to pre-defined rule that UE can be used only on PCell to control object for original power, and when receiving other one or more PDCCH on PCell, the TPC field of the PDCCH of one or more correspondence can be interpreted as ARI by UE.

If TPC field is not used in original object, then UE possible loss comprises the PDCCH of TPC field controlled for power, if or BS do not dispatch PDCCH, then slightly may reduce the dynamic control performance that the UL transmitting power for UE is determined.But the TPC value in PDCCH is not absolute value but for the relativity shift value of previous transmitting power.And, even if TPC value does not upgrade once or twice by UE, also default transmitting power can be kept.Except being used in the transmit power controlling method of the TPC field in PDCCH, also provide supplementary Poewr control method (this departs from scope of the present invention, and therefore, will not describe in detail).Therefore, the loss of TPC value does not have considerable influence for network performance.

In application the present invention, may be used for original object (power control object) according to the TPC field of one or more PDCCH of pre-defined rule on PCell.Below, the example of pre-defined rule will be described.

As the first example, the TPC Field Definition of the PDCCH launched in the n-th subframe of subframe can will bundled for being used for original object.At this, n can be the value of the one or more subframes being used to indicate part in binding subframe.Such as, if one of instruction binding subframe, then n can be defined as the value being used to indicate the 0th subframe or last subframe.And, differently can determine n according to the quantity of binding subframe (or size of binding subframe).In similar mode shown in table 12, the quantity of binding subframe can be such as 1,2,3,4 or 9.Or, the subframe of varying number can be bundled according to the binding scheme of new definition.And n can indicate the set of the multiple subframes in binding subframe.Such as, when n is 0 and 1, the TPC field of the PDCCH launched in the 0th and the 1st subframe in binding subframe may be used for original object.Therefore, if n has multiple value, then the quantity being received the PDCCH tested for rollback described below is increased the quantity of n value.Such as, if n has two values, then the quantity be received for the PDCCH of rollback test should be 2.In exemplary illustration below of the present invention, for convenience of description, n has a value.

As the second example, in binding subframe, the TPC field had in the PDCCH of the n-th DAI value can be defined for original object.At this, n can be 0,1,2,3 .... one of.Or, if DAI value is interpreted as 1,2,3,4 ..., then n can be defined as 1,2,3,4 .... a value.In this case, even if in the full multiplexer mode of ACK/NACK (wherein not applying the situation that time domain or CC territory (or frequency domain) bundle), also DAI field can be comprised by the one or more PDCCH on PCell.And, n can be determined with the form of the set of multiple value.Such as, when n is 0 and 1, this can indicate TPC field in the PDCCH with zero-sum the one DAI value for original object.Or when DAI value being interpreted as from 1, if n is 1 and 2, then the TPC field in the PDCCH with the first and second DAI values can be indicated as original object.Therefore, when n has multiple value, the quantity of the PDCCH of the received rollback test for describing later increases the quantity of n value.Such as, if n has two values, then the quantity be received for the PDCCH of rollback test should be 2.In explanation below of the present invention, for convenience of description, n has a value exemplarily.

In superincumbent second example, DAI value can represent continuous (sequentially) counter for one or more PDCCH distributed to UE with dibit size.The value of the actual transmission of DAI field can be can by UE one of be interpreted as DAI value 1,2,3 and 40,1,2 and 3 (or when being expressed as 2 bit value 00,01,10 and 11).DAI value about actual transmission and the DAI value explained by UE are described as follows.

The value of the actual transmission of DAI field can be 0,1,2 or 3, and this value can be interpreted as first, second, third or the 4th PDCCH by UE.In this case, about the DAI value of actual transmission, the n=0 (in the set of 0,1,2 and 3) in particular UE indicates a PDCCH.

The value of the actual transmission of DAI field can be 0,1,2 or 3, and this value can be interpreted as first, second, third or the 4th PDCCH by UE.In this case, about the DAI value explained by UE, the n=1 (in the set of 1,2,3 and 4) in particular UE indicates a PDCCH.

In a word, the actual DAI value 00,01,10 and 11 comprised at PDCCH can be mapped to the DAI value 1,2,3,4 explained by UE respectively.

As described in the above example, TPC field in one or more PDCCH of the n-th subframe or one or more PDCCH of DAI=n of being determined by the value of n is for original object (power control), and the TPC field in other one or more PDCCH can be used as ARI again.

Figure 31 is the flow chart being shown in example TPC field being used as under only PCell reception condition the ARI that PUCCH resource is determined.In the example of Figure 31, assuming that the TPC field of a specific PDCCH determined according to predefine rule is for original object, and the TPC field of other one or more PDCCH is used as ARI again.

In step S3110, UE can configure the PUCCH resource Candidate Set that (such as, RRC signaling) receives four resources comprised for PUCCH format 3 by higher level

{n_{P U C C H, 0}^{(3)}, n_{P U C C H, 1}^{(3)}, n_{P U C C H, 2}^{(3)}, n_{P U C C H, 3}^{(3)}} .

In step S3120, when PUCCH format 3 is launched for ACK/NACK, UE can determine that whether situation is only PCell reception condition.If whether (that is, non-only PCell reception condition) determination result in step S3120, then performs step S3130, and if for being (that is, only PCell reception condition), then perform step S3140.

In step S3130, UE can use and come to calculate/select a PUCCH resource (that is, a resource index) that will be used by it from four PUCCH resource candidates by the indicated ARI that reuses of the TPC field in one or more PDCCH of SCell.

Meanwhile, in step S3140, UE can determine whether the quantity of received PDCCH is 1.Because perform step S3140 when not receiving PDCCH on SCell, so the quantity of the PDCCH received indicates the quantity of the PDCCH received on PCell.If (namely the determination result in step S3140 for being, the quantity of the PDCCH that PCell receives is 1), then perform step S3150, and if the determination result in step S3140 be no (namely, the quantity of the PDCCH that PCell receives is greater than 1), then perform step S3160.

In step S3150, if UE only receives a PDCCH on PCell, then UE can use the TPC field of PDCCH for original object (power control), and because without any other PDCCH, so UE can determine not receive ARI value.In this case, limit UE to run under traditional LTE version 8 pattern.This can be called as the operation in fall-back mode.Fall-back mode is identical with the ACK/NACK firing operation of the PUCCH format 1a/1b using usual definition, and therefore, by description is omitted.The quantity about received PDCCH in step S3140 be whether 1 determination can be called as rollback test, wherein determine whether to apply fall-back mode.

Simultaneously, because perform step S3160 when the quantity of the PDCCH received on PCell is greater than 1, so UE can be used in TPC field in one of PDCCH for original application target, and the TPC field of other one or more PDCCH can be interpreted as ARI.Then, UE can use and come to calculate/select a PUCCH resource (that is, a resource index) that will be used by it from four PUCCH resource candidates by the indicated ARI that reuses of the TPC field in the PDCCH of PCell.

After step S3130 or step S3160, UE can use with resource corresponding to the index that calculates/select launch ACK/NACK information by PUCCH format 3.

In the examples shown of Figure 31, under following hypothesis, give explanation: UE only check receive the quantity of the PDCCH of (or detect), and when the quantity working as received PDCCH is 1, the TPC field of corresponding PDCCH is used for original object.

But if the quantity of the PDCCH received is 1, then the TPC field of PDCCH may be used for original object and maybe can be reused for ARI object.Therefore, when the quantity of received PDCCH is 1, does not always perform fall-back mode operation, and preferably, perform detailed determination.

Figure 32 is the flow chart of another example when being shown in only PCell reception, TPC field being used as the ARI that PUCCH resource is determined.In the example of Figure 31, assuming that the TPC field of a specific PDCCH determined according to predefine rule is for original object, and the TPC field of other one or more PDCCH is used as ARI again.

In the examples shown of Figure 32, omit the explanation of the operation (step S3210, S3220, S3230 and S3240) identical with the operation of Figure 31.

When the determination result of step S3240 is for being (that is, when the quantity of the PDCCH received on PCell is 1) perform step S3250.In step S3250, determine whether this PDCCH received is predefined PDCCH (that is, whether the TPC field of PDCCH is for original object).Such as, can determine whether received PDCCH is the PDCCH in the first subframe of binding subframe.As another example, can determine whether received PDCCH is the PDCCH with DAI value 1 (following, DAI=1).If determination result is yes, then perform step S3260, and if no, then perform step S3270.

In step S3260, because the TPC field in a PDCCH received should be used for original object, so UE can regard ARI as the unknown, and can run in fall-back mode (using the ACK/NACK of PUCCH format 1a/1b to launch).

Step S3270 can be performed when the result of step S3240 is no.That is, if the quantity of the PDCCH received is greater than 1, then because supposition only exist one wherein TPC field be used for the PDCCH of original object, so UE can identify that the TPC field of at least one PDCCH is used as ARI again.UE can use the ARI value of the TPC field of self-corresponding PDCCH to come in four PUCCH resource candidates, calculate/select a PUCCH resource (that is, a resource index) that will be used by it.

When the determination result of step S3250 is no, also step S3270 can be performed.That is, if the quantity of the PDCCH received is 1, then because corresponding PDCCH be not wherein TPC field for the PDCCH of original object, so the TPC field that UE can identify a corresponding PDCCH is reused for ARI.UE can use the ARI value of the TPC field of self-corresponding PDCCH to calculate/select the PUCCH resource (that is, a resource index) that will be used by it in four PUCCH resource candidates.

In step S3270, UE can use with resource corresponding to the index that calculates/select launch ACK/NACK information by PUCCH format 3.

embodiment 4-1

Embodiment 4 relate to receive at only PCell situation (that is, only receive for one or more PDSCH of PCell situation or on PCell, only receive the situation of one or more PDCCH) under in binding subframe, apply the example of identical ARI value.

The terms bundled subframe (or bundled window) that uses in explanation of the present invention represents the unit be made up of DL subframe when being launched the ACK/NACK response of launching for the DL in the DL subframe in bundled window by a ULPUCCH, instead of in time domain or CC territory (or frequency domain) actual perform bundle unit.

Such as, in LTE version 8TDD system, as superincumbent table 12 (illustrates DL relevant episode index K:{k ₀, k ₁... k _m-1) shown in, give about which previous one or more DL subframe (subframe n-k) for launching the definition responded for the ACK/NACK of the DL wireless communication system in specific UL subframe (subframe n).Describe in binding subframe in the example by table 12, when launching the ACK/NACK response of launching for the DL in specific one or multiple DL subframe in specific UL subframe, this specific one or multiple DL subframe be called as binding subframe.Such as, in UL-DL configuration 4, the binding subframe for UL subframe 2 is DL subframe 12,8,7 and 11, and the binding subframe for UL subframe 3 is DL subframe 6,5,4 and 7.

If use PUCCH format 3 in TDD, then can launch as described above by a UPPUCCH ACK/NACK response that the DL in multiple DL subframe is launched.At this, according to the above embodiments 4, in multiple DL subframe, detect multiple PDCCH when only PCell receives.If different, then ambiguous by ARI (or TPC) value had indicated by the PDCCH of the TPC field that is again used as ARI, which ARI value is used for calculating/selection PUCCH resource.

At this, except have according to predefine rule be confirmed as the TPC field of original object PDCCH such as, there is the PDCCH of DAI=1) outside, have and can be corresponded to PDCCH (such as, there is the PDCCH of the DAI value (hereinafter referred to as DAI>1) being greater than 1) by the PDCCH of the TPC field being again used as ARI.

Therefore, in order to prevent this problem, should equally remain on binding subframe in launch on PCell, have by be again used as ARI TPC field PDCCH (namely, except having the PDCCH except for the PDCCH of the TPC field of original object) ARI value (that is, the value of TPC field).

embodiment 4-2

Embodiment 4-2 relates to the example applying identical ARI value on the CC of binding.

The CC (or bundled window) of the terms bundled used in explanation of the present invention represent with binding in the presence/absence of irrelevant, when being launched the ACK/NACK response for the DLCC in bundled window by a ULPUCCH, the unit be made up of DLCC, instead of the unit in fact performing binding in time domain or CC territory (or frequency domain).Such as, when apply ACK/NACK complete multiplexing time, the CC of binding can have the implication identical with the quantity of the CC configured for UE.

If use PUCCH format 3 in TDD or FDD system, then the ACK/NACK that can launch for multiple DLCC as described above by a ULPUCCH responds.At this, launch the implication that the ACK/NACK for multiple DLCC responds and can correspond to the situation that wherein there is DL and launch on PCell and one or more SCell.Now, if the ARI value in the PDCCH of TPC field with the ARI be used as on PCell is different from the ARI value in the PDCCH on SCell, then ambiguous, which ARI value is used for calculating/select PUCCH resource.

Therefore, in order to prevent such problem, the value of the value that equally should keep the field of the ARI be used as on PCell (TPC field) and the field (TPC field) that is used as the ARI on SCell.

At this, can equally remain on PCell, with except being determined to use TPC field to come for original object PDCCH (such as according to predefine rule, there is the PDCCH of DAI=1) outside the ARI value of PDCCH (such as, there is the PDCCH of DAI>1) and the ARI value on SCell.

embodiment 4-3

Embodiment 4-3 relates to the example applying identical ARI value in the CC and subframe of binding.

Namely, when to consider the above embodiments 4-1 and 4-2 simultaneously (such as, when multiple CC and multiple subframe become a binding unit), if the ARI value in corresponding community or corresponding subframe is different, then it may be ambiguous for calculating/select PUCCH resource.Therefore, equally should remain on the ARI in the PUCCH on PCell and SCell, and simultaneously, equally should remain on the ARI in the PDCCH in multiple subframe.

At this, on PCell, can equally be kept for except be determined to according to predefine rule to use TPC field come for original object PDCCH (such as, there is the PDCCH of DAI=1) outside the ARI value of PDCCH (such as, there is the PDCCH of DAI>1).

To be diagram use TPC field for the figure of the embodiment of original object or ARI object according to DAI value on PCell to Figure 33.

DAI field value is used as the stored counts device of the PDCCH of each community.That is, DAI value is sequentially increased 1 in each PUCCH of a community.Always in all subframes, there is not PDCCH.

In the examples shown of Figure 33, on PCell, there is first and the 3rd the PDCCH being used for DL and distributing in subframe.DAI value is 0 in the PDCCH of the first subframe, and is 1 in the PDCCH of the 3rd subframe.On SCell, in the PDCCH distributed for DL, sequentially provide DAI value.In fig. 33, illustrate DAI value 0,1,2,3,0,1,2,3 ... but, from the viewpoint of UE, these values have with DAI value 1,2,3,4,1,2,3,4 ... identical implication.

With above-described embodiment 4 relatively, according to the DAI value on PCell, the TPC field in PDCCH may be used for original object or ARI object.Such as, DAI value wherein on PCell is the TPC field the PDCCH of 0 (or being 1 viewed from the viewpoint of UE), namely, (namely TPC field in PDCCH in first subframe of PCell is in fig. 33 used for original object, power controls), and the TPC field in another PDCCH on PCell is reused for ARI object.

With in the above embodiments 4-1 to 4-3 relatively, can equally remain on binding subframe and/or binding community in ARI value.Such as, if application bundle window on four subframes in the examples shown of Figure 33 and five communities, then (namely UE can suppose the TPC field of the PDCCH on PCell and SCell, TPC field for ARI object) value identical, outside the TPC field (wherein, DAI is 0) in first subframe of PCell.

embodiment 5

Embodiment 5 relates to the method using TPC field to come for PUCCH resource distribution under only PCell reception condition (that is, only receiving the situation being used for one or more PDSCH of PCell or the situation only receiving one or more PDCCH on PCell).Embodiment 5 is applied to part ACK/NACK binding.Partly bundle the binding referred to only in the time domain or in CC territory (or frequency domain).

DAI field is substantially for original object (that is, for the stored counts device of the PDCCH on each community) as in superincumbent embodiment 4, and TPC field in PDCCH can be used as ARI again.In this case, the TPC field of predetermined specific PDCCH is used for original object.Specific PDCCH can be defined as the PDCCH (describe this part in superincumbent embodiment 4, and therefore, the repetitive description thereof will be omitted) of the n-th subframe in binding subframe.Or, can determine that wherein TPC field is for the PDCCH of original object based on DAI value.

Example above Figure 31 or 32 substantially can be applied to embodiment 5 in the same manner as basic operation, and the repeat specification provided in omitting superincumbent embodiment 4.

Below, TPC field is used to be used for the method detailed of original object or ARI object when applying portion ACK/NACK bundlees based on DAI value description.

First, the TPC field had in the PDCCH of the n-th DAI value in the binding subframe of PCell can be defined for original object.The value of DAI field can be given 0,1,2,3 ... or can be given 1 viewed from the viewpoint of UE, 2,3,4 ....

In this case, in ACK/NACK part tie-in mode (being applied to time domain binding or CC territory (or frequency domain) binding), DAI field can be comprised by the one or more PDCCH on PCell.At this, the value of the DAI field comprised at one or more PDCCH of PCell should be determined based on pre-defined rule, and below by describe the present invention to its detailed suggestion.

When applying ACK/NACK part and bundling, if the TPC field in the PDCCH of DAI=n is used for original object (power control), then can determine that the DAI field of one or more PDCCH is as follows in every way.

In tradition (LTE version 8) tdd mode, the accumulated value of the PDCCH that DAI instruction distributes to UE, and if simply to multicarrier environment application DAI, then DAI can be used as the accumulated value to the PDCCH of UE distribution on whole community (or CC).Such as, as shown in Figure 34, when in four sub-frames and apply on two CC ACK/NACK binding time, can determine DAI value make DAI value in bundled window CC index increase direction on increase.But, be difficult to the program is applied to part binding.Therefore, configuring in the LTE version 10TDD pattern of multiple CC (or community) wherein, needing to provide another kind of for determining the method for DAI value.

Figure 35 is the figure being shown in the example determining DAI value in CATDD system.

Exemplarily, DAI value can indicate the cumulative amount (Figure 35 (a)) to the PDCCH of UE distribution in multiple subframes of each community.Such as, such method for determining DAI value is preferably used when application bundle in the time domain.Can with the cumulative amount of the mode application PDCCH of the PDCCH in all subframes of counting in a radio frame.Or, can in the mode of the PDCCH in counting actual bundled window in the time domain (in fact performing the unit of ACK/NACK binding) to apply the cumulative amount of PDCCH.In the example of Figure 35 (a), DAI in PDCCH in three subframes in the actual bundled window of the unit of the subframe of four on SCell#2 is defined as 0,1 and 2, and this is the example using DAI field to be used as stored counts device, and it is a PDCCH, the 2nd PDCCH and the 3rd PDCCH respectively that this stored counts device is used to indicate corresponding PUCCH.

As another example, DAI value can to indicate in each subframe the sum (Figure 35 (b)) of the PDCCH distributed to UE on multiple CC (or community).Such as, when preferably using such DAI value defining method during applying portion binding in CC territory.The sum of PDCCH can be defined as the quantity of the PDCCH in all CC that UE is configured.Or, the sum of PDCCH can be defined as the quantity of the PDCCH in the actual bundled window (performing the unit of ACK/NACK binding for reality) in CC territory.In the example of Figure 35 (b), the DAI value in the PDCCH in the first subframe is 2, and the example of this to be the sum using DAI field to be used as the PDCCH be used to indicate in the subframe of correspondence be designator of 3.

Or, DAI value can be defined as the stored counts device to the PDCCH of UE distribution in the multiple CC (or community) in each subframe.According to the ascending order of the CC index (or cell index) in all CC configured for UE or the ascending order according to the CC index (or cell index) in the actual bundled window in CC territory, the cumulative amount each PDCCH being counted to PDCCH can be carried out.Such as, in the example of Figure 35 (b), the DAI value in the 3rd subframe is defined as the DAI=0 on PCell, the DAI=1 on SCell#2, the DAI=2 on SCell#3 and the DAI=3 on SCell#4.

As shown in Figure 35 (a), if (namely DAI is used as the stored counts device of the PDCCH distributed in actual bundled window in the time domain, if reset DAI value on each CC), then can apply the embodiments of the invention using the TPC field of the PDCCH on the external PCell of PDCCH except having the specific DAI value (such as, DAI=0) on PCell and multiple SCell to come for ARI object equally.

Simultaneously, as as shown in Figure 35 (b), if DAI is used as the sum (or stored counts device) of the PDCCH distributed in the actual bundled window in CC territory (or frequency domain), then may be difficult to apply the embodiments of the invention using the TPC field of the PDCCH on the external PCell of PDCCH except having the specific DAI value (such as, DAI=0) on PCell and multiple SCell to come for ARI object.

Such as, can suppose, in the first subframe and the second subframe, distribute PDCCH to specific UE, and on SCell, do not distribute PDCCH.Although this situation corresponds to only PCell and receives, but the DAI value of the PDCCH received by UE in these two subframes identical (such as, DAI=0) (if DAI field is used as designator or the stored counts device of the sum of the PDCCH in corresponding subframe, then according to hypothesis above, DAI value is 0).Then, ambiguous for UE, determine that the TPC field of which PDCCH in two PDCCH on PCell is for ARI object, and the TPC field of which PDCCH is used for original object.In other words, if determine DAI value by the reset schemes of the DAI value of each subframe, then can not apply the embodiments of the invention using the TPC field of the PDCCH on the external PCell of PDCCH except having the specific DAI value (such as, DAI=0) on PCell and multiple SCell to come for ARI object.

In order to solve problem above, different DAI value defining method can be applied on PCell and SCell.Such as, on SCell, DAI can be used as the stored counts device of the PDCCH distributed in the actual bundled window in frequency domain (or CC territory), and on PCell, DAI can be used as the designator (or stored counts device) of the sum of the PDCCH distributed in actual bundled window in the time domain.

Or, in order to apply the present embodiment, need the stored counts device DAI at least on PCell being defined as PDCCH in the time domain.Therefore, the DAI of the one or more PDCCH on PCell can be used as the stored counts device of the PDCCH distributed in actual bundled window in the time domain, and can with the identical or different mode of the DAI used on PCell to be used in the DAI of the one or more PDCCH on SCell.

Following by the example of the present invention of description, assuming that the DAI field of PDCCH is used as follows.

First, the binding that the DAI field in PDCCH can be used as each CC check in multiple subframes in the stored counts device of PDCCH that distributes.That is, each CC determines DAI value independently.At this, the bit value 0,1,2 and 3 of DAI field indicates stored counts 1,2,3 and 4 respectively.That is, the bit value being expressed as 0,1,2 and 3 viewed from the viewpoint of DAI field also can be expressed as 1,2,3 and 4 viewed from the viewpoint of the DAI value explained by UE.

Next, the designator of the sum of the PDCCH that the multiple CC during the DAI field of PDCCH also can be used as in each subframe bundled window distribute.The bit value 0,1,2 and 3 of DAI field can indicate sum 1,2,3 and 4 respectively.That is, the bit value being expressed as 0,1,2 and 3 viewed from the viewpoint of DAI field also can be expressed as 1,2,3 and 4 from by viewed from the viewpoint of UE.

Figure 36 to 39 diagram is used in the various examples of the DAI field in the binding of CC territory.In the example of Figure 36 to 39, illustrate and 5 CC of UE configuration and the 4DL-1UL in TDD are configured (that is, collecting the ACK/NACK launched for the DL in four DL subframes to respond to carry out transmitting response by the PUCCH of a UL subframe).In addition, in the examples shown of Figure 36 to 39, bundled window comprises 5 CC and four subframes.But the largest amount illustrating wherein actual bundled window in Figure 36 to 39 is the situation of 4,5 or 2.

Figure 36 diagram does not wherein apply the example (largest amount of the actual bundled window in CC territory is 4) of CC territory binding on PCell.In this case, the DAI field of PCell is used as the stored counts device of the PDCCH to the sub-frame allocation on PCell.The DAI field of SCell can be used as the designator of the sum of the PDCCH distributed to SCell, except the PCell in each subframe.

Figure 37 diagram does not wherein apply the example (largest amount of the actual bundled window in CC territory is 4) of CC territory binding on PCell.In this case, the DAI field of PCell is used as the stored counts device of the PDCCH to the sub-frame allocation on PCell.The DAI field of SCell can be used as the designator to the sum of the PDCCH of PCell and SCell distribution in each subframe.Therefore, the sum (that is, the sum of the PDCCH on PCell and SCell) of the PDCCH distributed by BS in the subframe of correspondence can be known according to the DAI of SCell, UE.The PDCCH that UE can use the DAI of PCell and fail to detect/receive in actual bundled window to determine whether there is UE about the information of the sum of distributed PDCCH.Therefore, it is possible to the CC territory ACK/NACK effectively performed in the subframe of correspondence bundlees.

Such as, in the examples shown of Figure 37, if the DAI value in the PDCCH detected by UE on SCell in the second subframe is 2, then UE can be identified in the sum of the PDCCH that PCell and multiple SCell distributes is 3.At this, can suppose that UE does not receive PDCCH in SCell#2.In this case, can not determine by means of only the DAI value on SCell the PDCCH that do not receive be whether in actual bundled window (namely, on SCell) PDCCH or PDCCH in the window (that is, on PCell) except actual bundled window.Because the DAI value on PCell is given stored counts in the time domain, so UE can confirm that on PCell first and the 3rd sequentially provides DAI value in subframe, and therefore confirm not exist the PDCCH that UE fails to detect on PCell.As a result, UE can know that PDCCH detects one of the SCell in the second subframe middle failed situation.

Figure 38 diagram wherein independently applies the example (largest amount of the actual bundled window in CC territory is 5) that CC territory bundlees with PCell or SCell.In this case, the DAI field of PCell is used as the stored counts device of the PDCCH to the sub-frame allocation on PCell.The DAI field of SCell may be used for the sum indicating the PDCCH distributed on PCell and SCell in each subframe.Therefore, UE can know the sum (sum of the PDCCH in PCell and SCell) of the PDCCH distributed by BS in subframe by the DAI of SCell.Because the quantity of the PDCCH of DAI value instruction in actual bundled window, so UE can determine whether there is UE in actual bundled window fail the PDCCH detecting/receive.Therefore, it is possible to the CC territory ACK/NACK effectively performed in the subframe of correspondence bundlees.

The largest amount that Figure 39 illustrates the wherein actual bundled window in CC territory is the situation of 2.Now, PCell does not apply the binding of CC territory, and, two actual bundled windows with largest amount 2 can be configured on four SCell.The DAI field of PCell is used as the stored counts device of the PDCCH to the sub-frame allocation on PCell.The DAI field of SCell can be used as the designator of the sum of PDCCH except the PCell in each subframe, that distribute on SCell (maximum two SCell) in actual bundled window.

ACK/NACK part binding (binding in a time domain or in a frequency domain) is applied, even and if in this case, when the ARI (=TPC field) value in bundled window is different, ACK/NACK bundling operation may be unclear to embodiment 5.

Therefore, under only PCell reception condition, can equally keep the TPC field wherein in binding subframe on PCell to be reused for the ARI value of the PDCCH (that is, except wherein TPC be used for except the PDCCH of original object) of ARI object.In addition, on the CC of binding, can equally remain on value for the field (=TPC field) of ARI object on PCell with the value of the field (=TPC field) for ARI object on SCell.And, on binding CC and subframe, can equally remain on PCell except be confirmed as according to predefine rule using TPC field come for original applications PDCCH (such as, there is the PDCCH of DAI=1) outside the ARI value of PDCCH (such as, there is the PDCCH of DAI>1).Ground related to this, the principle of the present invention described in superincumbent embodiment 4-1 to 4-3 can be applied to the present embodiment 5 in an identical manner.In order to clear, omit the explanation of repeating part.

the ULACK/NACK launched for the DLSRS in multicarrier back-up system launches

LTE version 8 system supports SPS.If have activated DLSPS to launch, then can allocate the time/frequency resource of launching for SPS in advance by PDCCH, and the PDSCH not having corresponding PDCCH can be launched by the resource of distributing.

The ACK/NACK relevant to SPS feedback can be divided into two types.One type is launched in subframe n for ' indicating the ACK/NACK feedback of the PDCCH ' of the DLSPS release detected by UE in one or more n-k.Another kind of type is in subframe n, launch the ACK/NACK feedback for ' not having the PDSCH of corresponding PDCCH to launch in one or more subframe n-k '.The first type corresponds to following situation: wherein, if there is PDCCH (wherein, k can be one or more value) in the n-th-k subframe, then the ACK/NACK launched in the n-th subframe for this PDCCH feeds back.The second type corresponds to following situation: wherein, if launched not having to receive SRS in the n-th-k of other PDCCH subframe after SPS activates, then in the n-th subframe, launches the ACK/NACK that the SPS for correspondence launches regularly feed back.Relevant detailed description is launched for SPS, can reference paper 3GPPTS36.213.

Substantially the PUCCH resource index for ACK/NACK feedback in LTE version 8 system determined in the CCE index based on PDCCH.If the ACK/NACK response in a PUCCH in the n-th subframe comprises the ACK/NACK response for the one or more PDCCH (comprising the PDCCH of general PDCCH and instruction DLSPS release) in the n-th-k subframe, then can draw PUCCH resource index from the CCE index of PDCCH.But, if should only launch, the ACK/NACK of the SPS of PDCCH that do not have in the n-th-k subframe is responded, then can not determine the PUCCH resource index for ACK/NACK response.In order to solve such problem, in LTE version 8 system, indicate for only there is ' not having the PDSCH of corresponding PDCCH to launch ' (namely in advance by RRC signaling, SPSPDSCH launches) the PUCCH resource indexed set (set such as, be made up of four PUCCH resource indexes) of situation.And, determine whether by the TPC field in the PDCCH of instruction SPS activation the PUCCH resource using PUCCH resource indexed set.Define in the table 14 illustrated below at the PUCCH resource index for DLSPS and the mapping relations between the value of TPC field.

[table 14]

If perform above-mentioned DLSPS to launch in multicarrier back-up system, then must provide the ACK/NACK launching technique considering that DLSPS launches.

Describe under following prerequisite this each embodiment of the present invention: be similar to the above embodiments 4 and 5, for the PCell of particular UE a PDCCH (have DAI=1 (DAI=1,2,3,4 ...) PDCCH) TPC field be used for original object power control object, and the TPC field of other one or more PDCCH be used for ARI object.It should be noted that such hypothesis is for clarity, and application example of the present invention is not limited thereto.That is, ARI information can be provided by additive method.

When launch in the n-th subframe in the n-th-k subframe ' not having the PDSCH of corresponding PDCCH to launch ' (hereinafter referred to as ' and there is no the SPS ' of PDCCH) ACK/NACK response time, the SPS not having PDCCH can be received in the n-th-k subframe, and a PDCCH in addition, can also be detected.Then, the ACK/NACK launched for PDCCH is needed to respond in response to the ACK/NACK for the SPS not having PDCCH.At this, if a PDCCH detected is a PDCCH (such as, having the PDCCH of DAI=1), then because the TPC field of PDCCH is used for original object, so this situation is when UE does not receive ARI information.Therefore, UE can not determine the resource index for PUCCH format 3.Below, the of the present invention various embodiment solving problem is above used description to.

In the following description, ACK/NACK is needed to launch in one of three kinds of situations below.In a word, situation 1 is for ' have the ACK/NACK of the PDSCH ' of PDCCH, situation 2 is for ' DLSPS discharges the ACK/NACK of PDCCH ', and situation 3 is the ACK/NACK for ' DLSPSPDSCH '.

Situation 3 can be called as ' do not have the PDSCH ' of corresponding PDCCH, for ' do not have the SPS ' of PDCCH ACK/NACK or referred to as the ACK/NACK for ' SPS '.In situation 1, ' PDCCH with the PDSCH ' of PDCCH can be called as ' corresponding to the PDCCH ' of PDSCH.

embodiment 6

Embodiment 6 relates to for always using PUCCH format 3 to launch the method for ACK/NACK response.

Can be indicated only for the PUCCH format 3 resource index collection of SPS to UE by RRC signaling.Such as, can to UE provide about with the form shown in superincumbent table 13 by with the information of the set formed.In addition, which resource index that will use PUCCH format 3 resource index collection can be specified by the TPC field be used to indicate in the PUCCH of SPS activation.

Exemplarily, when needing only for when there is no an ACK/NACK feedback of SPS of PDCCH, specific PUCCH format 3 resource index indicated by PDCCH can be activated by the SPS in the set of RRC configuration by choice and operation.That is, PUCCH format 3 can be used to launch only for there is no the ACK/NACK of the SPS of PDCCH.

As another example, method below can be applied to wherein to be needed for ' not having the SPS ' of PDCCH and ' have the situation of the ACK/NACK feedback of a PDSCH ' of PDCCH.

First method is that choice and operation activates PUCCH format 3 resource index indicated by PDCCH by SPS.That is, PUCCH format 3 also can be used to launch for ' there is no the SPS ' of PDCCH and ' have the ACK/NACK response of a PDSCH ' of PDCCH.

According to whether at one, ' PDCCH ' corresponding to PDSCH comprises ARI information, and second method is further divided into two kinds of methods.

When one ' PDCCH ' corresponding to PDSCH be do not comprise ARI information PDCCH (such as, the wherein PDCCH of a DAI (DAI=1)) time, PUCCH format 3 resource index indicated by PDCCH can be activated by SPS by choice and operation.That is, even if from ' PDCCH ' corresponding to PDSCH does not get ARI information, and PUCCH format 3 also can be used to launch for ' not having the SPS ' of PDCCH and ' have the ACK/NACK response of a PDSCH ' of PDCCH.

If one ' PDCCH ' corresponding to PDSCH is the PDCCH (such as not having DAI (DAI>1) PDCCH) (this situation can be when UE loss has the PDCCH of a DAI) comprising ARI information, then use by ' PUCCH format 3 resource index corresponding to the ARI value indicated by the TPC field in the PDCCH ' of PDSCH can by choice and operation.

Simultaneously, when transmitting comprises for ' when not having multiple ACK/NACK feedback of the ACK/NACK of the SPS ' of PDCCH, PUCCH format 3 resource index can be determined by the ARI value indicated by the TPC field by second on PCell or more PDCCH one or more PDCCH of DAI>1 (such as, wherein) or the one or more PDCCH on one or more SCell.

embodiment 7

Embodiment 7 relates to for operating the method ' only ' always in fall-back mode not being had to the ACK/NACK of the transmitting of the SPS of PDCCH.At this, fall-back mode refers to launches according to the ACK/NACK of the operation of definition in LTE version 8, such as, uses the ACK/NACK of PUCCH format 1a/1b to launch.On the other hand, about for ' ACK/NACK not having the SPS ' of PDCCH and other DL to launch (having the PDSCH of PDCCH) launches, and can use PUCCH format 3.

For this reason, can be used for UE instruction the PUCCH format 1a/1b resource index collection launching ' only ' SPS by RRC signaling.Can configuration as shown in table 14 or can according to other arrangements PUCCH format 1a/1b resource index collection.When indicating SPS to activate, which index that will use PUCCH resource indexed set can be specified by the TPC field activated in PDCCH at SPS.

Because preset the time/frequency resource of launching for SPS between BS and UE, when transmit and receive for ' not having the ACK/NACK of the SPS ' of PDCCH to feed back so BS and UE knows.Therefore, comprising in the bundled window for the SPS of particular UE, BS can use the TPC field of all PDCCH to come for ARI object, and distinguishes respectively between PUCCH not on PCell.Namely, during the transmitting of only ACK/NACK of the SPS not having PDCCH being fed back, the one or more PDCCH launched in the bundled window comprising the SPS not having PDCCH can use all TPC fields to come for ARI object, and do not distinguish between PCell and multiple SCell.

In this case, launch the ACK/NACK feedback for the SPS not having PDCCH about PUCCH, the TPC field of PDCCH is not used in original object (control of UL transmitting power).But the TPC value in PDCCH is the relativity shift value for previous transmitting power, instead of absolute value, even and if UE by TPC value upgrade not once or twice, also keep default transmitting power.Except being used in the transmit power controlling method of the TPC field in PDCCH, additionally provide supplementary Poewr control method.And, when needing the transmitting of the SPS not having PDCCH in fdd mode, limit the TPC value that UE can not obtain original object.Therefore, even if when not applying the TPC of original object, the operation described in example above of the present invention in TDD also affects network performance indistinctively.

According to the example of embodiment 7, when needing only for when there is no an ACK/NACK feedback of SPS of PDCCH, specific PUCCH format 1a/1b resource index indicated by PDCCH can be activated by the SPS of set that configured by RRC of choice and operation.That is, for only for there is no the ACK/NACK of the SPS of PDCCH, the fall-back mode operation using PUCCH format 1a/1b can be performed.

As another example, when needing the ACK/NACK having a PDSCH ' of PDCCH for ' do not have the SPS ' of PDCCH and ' to feed back, because the TPC field of all PDCCH as mentioned above in bundled window is used for ARI object, so the ARI value indicated by the TPC field of the PDCCH detected by choice and operation PUCCH formatization 3 resource index can be carried out.

Simultaneously, when launching the multiple ACK/NACK feedback comprised for the ACK/NACK of the SPS not having PDCCH, because the TPC field of all PDCCH as mentioned above in bundled window is used for ARI object, so can determine PUCCH format 3 resource index by the one or more ARI values indicated by the TPC field of the one or more PDCCH on PCell and/or SCell.

embodiment 8

Embodiment 8 relates to a kind of method for always performing the ACK/NACK launched for the DL not having ' comprising ' SPS of PDCCH to launch in fall-back mode.

For this reason, can be used for UE instruction the PUCCH format 1a/1b resource index collection that " only " does not have the transmitting of the SPS of PDCCH by RRC signaling.Can configuration as shown in table 14 or PUCCH format 1a/1b resource index collection can be configured according to other schemes.When indicating SPS to activate, which index of PUCCH resource indexed set can be used by the TPC field appointment activated at SPS in PDCCH.

According to the example of embodiment 8, when needing to be used for ' only ' and there is no the ACK/NACK feedback of the SPS of PDCCH, specific PUCCH format 1a/1b resource index indicated by PDCCH can be activated by the SPS of set that configured by RRC of choice and operation.That is, for the ACK/NACK of SPS only not having PDCCH, the fall-back mode using PUCCH format 1a/1b can be performed.At this, for not having the ACK/NACK of the SPS of PDCCH to feed back the size can with 1 or 2 bits, and PUCCH format 1a or 1b can be used.

As another example, need the ACK/NACK feedback ' do not have the SPS ' of PDCCH and ' to a PDSCH ' of PDCCH, can the specific PUCCH format 1a/1b resource index of SPS activation indicated by PDCCH of set that configured by RRC of choice and operation.That is, even if feed back for the ACK/NACK of the transmitting comprising the SPS not having PDCCH, the fall-back mode using PUCCH format 1a/1b can be performed.At this, according to there is for ' do not have the SPS ' of PDCCH and ' quantity of the code word of each of a PDSCH ' of PDCCH and needing 2 bit to 4 bit feedback payload non-application space binding (this is because when produce 1 bit ACK/NACK Response field bit about a code word).

Below, will describe when needing for ' there is no the SPS ' of PDCCH and ' there is the detailed example of the present invention during the ACK/NACK feedback of a PDSCH ' of PDCCH.

embodiment 8-1

Embodiment 8-1 relate to use when needs to have the ACK/NACK feedback of a PDSCH ' of PDCCH for ' do not have the SPS ' of PDCCH and ' M=2,3 or 4 the method for channel selection profile.Namely, the size that the ACK/NACK having a PDSCH ' of PDCCH for ' do not have the SPS ' of PDCCH and ' feeds back payload is 2 to 4 bits, and in order to launch ACK/NACK feedback without any loss, the channel selection profile of use 2,3 or 4 PUCCH format 1b (or PUCCH format 1a) can be applied.When being used in the channel selection profile for PUCCH format 1b (or 1a) of definition in LTE version 8, this can be expressed as and use the channel selection profile of LTE version 8 to operate under fall-back mode.

For in multiple resources of Channel assignment, from ' the CCE index corresponding to the PDCCH ' of PDSCH draws PUCCH format 1b (or 1a) resource, and the PDCCH that can activate by being used to indicate SPS indicates another PUCCH format 1b (or 1a).ACK/NACK information can be launched by the channel selection profile of one of selection two PUCCH format 1b (or 1a) resources.

In addition, if need PUCCH resource further (such as, M=3 or 4), then with the skew (such as, 1) by adding regulation to the CCE index of " PDCCH corresponding to PDSCH " and PUCCH resource corresponding to the value (CCE index+skew) that obtains may be used for Channel assignment.Replace or supplement based on ' corresponding to the other resource of the CCE index of the PDCCH ' of PDSCH, activate by SPS resource index that PDCCH assigns and PUCCH resource corresponding to the value that obtains may be used for Channel assignment with by adding to the skew specified (such as, 1).

Or, be similar to scheme above, following channel selection profile can be applied, namely use, to ' have the SPS ' of PDCCH and ', not there is the PUCCH format 1a/1b resource index that the relevant information of the PDSCH ' of PDCCH explicitly or implicitly determines.

When UE determines the PUCCH resource of launching ACK/NACK information according to embodiment 8-1, BS can attempt to receive the ACK/NACK information about PUCCH format 3 region, PUCCH format 1a/1b region and Channel assignment (PUCCH format 1b (or 1a)) these three kinds of situations of region.

Because UE can use any one of these three kinds of situations to launch ACK/NACK information, so BS should perform blind decoding above in three kinds of situations.

embodiment 8-2

Embodiment 8-2 relates to a kind of when needs feed back for the ACK/NACK that ' do not have the SPS ' of PDCCH and ' has a PDSCH ' of PDCCH, usage space binding (namely, ACK/NACK for multiple code word bundlees), the PUCCH format 1b (or 1a) being used in definition in LTE version 8 uses the method for fall-back mode.

First, when ' when there is no the transmitting of the SPS ' of PDCCH corresponding to multiple (such as, 2) code word, performing space binding for its ACK/NACK response.Similarly, when ' during the transmitting of a PDSCH ' with PDCCH corresponding to multiple (such as, 2) code word, performing space binding for its ACK/NACK response.' if do not have the SPS ' of PDCCH and ' have a PDSCH ' of PDCCH only one be a code word launch and another to be two code words launch, then only launch about two code words and perform space binding.

Therefore, make comparisons to 4 bits with 2 when not performing space and bundling, when performing space binding, for ' there is no the SPS ' of PDCCH and ' size with the ACK/NACK payload of a PDSCH ' of PDCCH is reduced to 2 bits.

2 bit ACK/NACK feedback can be launched by the PUCCH format 1b (or 1a) of traditional LTE version 8.That is, if perform space binding, then can use the PUCCH format 1b of LTE version 8 (or 1a) under fall-back mode, operate ACK/NACK feedback.

In this case, can choice and operation from ' extractive PUCCH format 1a/1b a resource index of the CCE rope corresponding to the PUCCH ' of PDSCH.Or, PUCCH format 1a/1b resource index indicated by PDCCH can be activated by the SPS that concentrated by the resource index configured at RRC of choice and operation.In other words, corresponding ACK/NACK response return back to PUCCH format 1a, and is re-used by phase rotating, that is, one of two ACK/NACK responses are mapped to I channel, and another is mapped to Q channel.Or two ACK/NACK responses return back to PUCCH format 1b and are re-used.

Such as, in the dibit ACK/NACK used in the PUCCH format 1b used in LTE version 8, highest significant position (MSB) can be mapped to for ' not having the ACK/NACK of the SPS ' of PDCCH, and least significant bit (LSB) (LSB) can be mapped to for ' having the ACK/NACK of a PDSCH ' of PDCCH (such as, having the PDCCH of DAI=1).Or, multiple ACK/NACK can be mapped in the contrary mode of example above.

As another embodiment, for ' not having the ACK/NACK of the SPS ' of PDCCH to be mapped to the I axle of QPSK constellation, and for ' ACK/NACK with a PDSCH ' of PDCCH (such as, having the PDCCH of DAI=1) can be mapped to the Q axle of QPSK constellation.Or, multiple ACK/NACK can be mapped in the mode contrary with example above.In addition, according to received sequential, for ' there is no the SPS ' of PDCCH and ' ACK/NACK first received with a PDSCH ' of PDCCH is mapped to I axle, and the ACK/NACK for reception afterwards can be mapped to Q axle.Or, multiple ACK/NACK can be mapped in the mode contrary with example above.

Such as, when for ' not having the ACK/NACK of the SPS ' of PDCCH to be mapped to I axle and ' there is PDCCH (such as, there is the PDCCH of DAI=1) a PDSCH ' when being mapped to Q axle, even if UE fails to detect that PDCCH (namely, ' PDCCH ' corresponding to PDSCH), then BS can receive the ACK/NACK response at least SPS.This is because, when UE fails PDCCH to be detected, when for ' do not have the constellation positions during ACK/NACK of the SPS ' of PDCCH mapped segment number I axle equal when use PUCCH format 1a use BPSK constellation (that is, I axle) launch ' only ' for ' there is no the constellation positions during ACK/NACK of the SPS ' of PDCCH.

As another example, ' 1 of QPSK constellation, 1' ' and ' 0,0 ' can be mapped to for ' not having the ACK/NACK of the SPS ' of PDCCH, and ' 0,1' ' and ' 1,0 ' can be mapped to for ' having a PDSCH ' ACK/NACK of PDCCH (such as, having the PDCCH of DAI=1).Or, corresponding multiple ACK/NACK can be mapped in the mode contrary to example above.

The emission mode that can be applied equally to wherein in each community of constellation mapping is above situation and other situations of MIMO mode.Also can apply constellation mapping above, and with whether in fact application space bundle irrelevant (that is, with whether exist 2 code words launches have nothing to do).

In Application Example 8-2, even can bundle to ' only ' for the ACK/NACK feedback application space of the SPS not having PDCCH.In this case, BS should perform blind decoding for following three kinds of situations: for the PUCCH format 1a/1b region of the ACK/NACK for ' only ' SPS, for for ' not having the SPS ' of PDCCH and ' have PUCCH format 1a/1b region and PUCCH format 3 region of the ACK/NACK of a PDSCH ' of PDCCH.

In addition, in Application Example 8-2, replace from ' corresponding to the extractive resource index of CCE rope of the PDCCH ' of PDSCH as PUCCH resource, the PUCCH resource index of SPS activation specified by PDCCH of the PUCCH resource collection configured by RRC can be used, and other parts can be applied equally.

embodiment 8-3

Embodiment 8-3 relates to the method for the channel selection profile of application space binding (that is, the ACK/NACK for multiple code word bundle) and use M=2 when needs to have the ACK/NACK feedback of a PDSCH ' of PDCCH for ' do not have the SPS ' of PDCCH and '.When being used in the channel selection profile for PUCCH format 1b (or 1a) of definition in LTE version 8, this can be expressed as the fall-back mode operation of the channel selection profile using LTE version 8.

First, for ' when there is no the transmitting of multiple (such as, two) code word of the SPS ' of PDCCH, performing space binding for its ACK/NACK response.Similarly, for ' when there is the transmitting of multiple (such as, two) code word of a PDSCH ' of PDCCH, performing space binding for its ACK/NACK response.If ' do not have the SPS ' of PDCCH and ' one of PDSCH ' with PDCCH is a code word and another is two code words, then only space binding is performed for the transmitting of two code words.

Therefore, for ' there is no the SPS ' of PDCCH and ' there is the size of the ACK/NACK payload of a PDSCH ' of PDCCH by 2 bits be reduced to from 2 bit to 4 bits when not performing space binding when performing space binding.

2 bit ACK/NACK feedback can be launched by the PUCCH format 1b (or 1a) of traditional LTE version 8.At this, the channel selection profile of the M=2 of PUCCH1b (/ 1a) is used to be used.That is, the 2 bit ACK/NACK that the fall-back mode of PUCCH format 1b (1a) can be used to launch as the result performing space binding feeds back.

At this, M=2 can represent the transmitting of the two kinds of ACK/NACK information (2 bit ACK/nack message) as space binding result, or can represent the Channel assignment of use two PUCCH resource.Therefore, can by the detection perform using Channel assignment to improve BS.

For in two PUCCH resource of Channel assignment, first PUCCH resource can use the PUCCH format 1a/1b resource index of being specified by SPS activation PDCCH, and the second PUCCH resource can use from ' the extractive PUCCH format 1a/1b resource index of the CCE rope corresponding to the PDCCH ' of PDSCH.Contrary with example above, the first and second PUCCH resource can be mapped to respectively and activate the PDCCH PUCCH resource index of specifying by SPS and from ' the extractive PUCCH resource index of the CCE rope corresponding to the PDCCH ' of PDSCH.ACK/NACK information can be launched by the channel selection profile of one of selection two PUCCH format 1b (or 1a) resources.

In the present embodiment, can as being such as configured in the Channel assignment mapping relations between ACK/NACK information and PUCCH resource as shown in table 5 or table 8.But this is only exemplary, and can define and use new Channel assignment mapping relations.

As the example of this embodiment, provide the channel mapping relation using PUCCH format 1b assuming that as shown in table 5.For channel mapping two PUCCH resource ( with ) in, the PUCCH resource of being specified by SPS activation PDCCH can be mapped to further, from ' the extractive PUCCH resource of CCE rope corresponding to the PDCCH ' of PDSCH can be mapped to such mapping configuration can be determined, and with ' there is no the SPS ' of PDCCH and ' reception order (time of reception) corresponding to the PDSCH ' of PDCCH is irrelevant.Such as, even if when (namely specific UE is losing PDCCH.' PDCCH ' corresponding to PDSCH) and after only receiving SPS during transmitting response, UE also can receive and at least respond for the ACK/NACK of this SPS.This is because, when UE fails PDCCH to be detected, for for ' there is no the PUCCH resource that the ACK/NACK of the SPS ' of PDCCH launches with the PUCCH resource of launching for the ACK/NACK of the SPS not having PDCCH for ' only ' identical.Meanwhile, as the modified example of this embodiment, can map on the contrary to example above or corresponding PUCCH resource and DL emission type (PUCCH or SPS) can be mapped according to the order of time of reception.

As another example of the present embodiment, in the channel mapping relation using PUCCH format 1b, (namely ACK/NACK for SPS can be mapped to the MSB of 2 bit ACK/NACK, ACK/NACK for SPS is mapped to the first bit), and, for ' there is PDCCH (such as, there is the PDCCH of DAI=1) the ACK/NACK of a PDSCH ' LSB (that is, the ACK/NACK for the PDSCH with PDCCH is mapped to the second bit) can be mapped to.Or, even if when be mapped to I axle for the ACK/NACK of SPS and for ' there is PDCCH (such as, there is the PDCCH of DAI=1) the ACK/NACK of a PDSCH ' when being mapped to Q axle UE fail to detect PDCCH (, ' PDCCH ' corresponding to PDSCH), the ACK/NACK that BS also can receive at least SPS launches responds.This is because when when PUCCH detects unsuccessfully for ' constellation positions when not having the ACK/NACK of the SPS ' of PDCCH to be mapped to I axle is identical with the constellation positions using PUCCH format 1a to use BPSK constellation (that is, I axle) to launch when not having the ACK/NACK of the SPS of PDCCH to respond for ' only ' as UE.Or, the mapping relations contrary with example above can be configured, and mapping can be performed according to the order of the time received.

At least the ACK/NACK of SPS being responded to ensure that BS receives, under various ACK/NACK feeds back transmitting situation, customizing messages can be mapped to specific PUCCH resource.Such as, can configurating channel Choose for user relation make the PUCCH resource that is mapped to of ACK/NACK of launching for SPS identical with the PUCCH resource of it being launched for the ACK/NACK of ' only ' SPS.

Table 15 below illustrates the modulation symbol (or constellation) for the PUCCH format 1a in traditional LTE version 8/9 and 1b.

[table 15]

In table 15, assuming that the value ' 0 ' of b (0) is NACK and ' 1 ' is ACK.So, the value ' 00 ' of b (0), b (1) represents ACK/ACK, and ' 11 ' represents NACK/NACK.In this case, at least one preceding bit b (0) has the modulation symbol identical with in PUCCH format 1a with 1b.In other words, b (0) when d (0)=1 in two PUCCH format 1a and 1b always 0, and when d (0)=-1 in two PUCCH format 1a and 1b always 1.Therefore, BS can receive and detect the information about at least one preceding bit b (0), even if BS does not know whether use PUCCH format 1a or PUCCH format 1b to launch received ACK/NACK feedback.Can configurating channel Choose for user relation, make for ' not having the ACK/NACK of the SPS ' of PDCCH to use the PUCCH resource being mapped to a previous Bit b (0).Therefore, BS can ensure at least for the reception of the ACK/NACK of SPS.

Such as, interior as M=2, the Channel assignment mapping relations shown in table 16 below can be used in.

[table 16]

In table 16, the ACK/NACK for SPS is mapped to HARQ-ACK (0), and for ' ACK/NACK with the PDSCH ' of PDCCH can be mapped to HARQ-ACK (1).

Such as, suppose only to receive the SPS with a code word, and do not receive and ' there is the PDSCH ' of PDCCH.In this case, PUCCH format 1a can be used launch the ACK/NACK for SPS to respond.

Meanwhile, ' when there is the PDSCH ' of PDCCH, can use according to Channel assignment of the present invention when receiving together with SPS.In this case, the PUCCH resource by configuring in the higher level for SPS is concentrated and can be used as table 16 by the SPS PUCCH resource activated indicated by PDCCH in addition, from ' PUCCH resource that the CCE index (by pre-defined rule implicitly) corresponding to the PDCCH ' of PDSCH draws can be used as table 16 in this case, the ACK/NACK that BS should receive for SPS responds, and whether lose with UE ' corresponding to PDSCH PDCCH ' have nothing to do.

As mentioned above, if the ACK/NACK that UE launches for SPS responds, then use at this, ACK corresponds to wherein b (0)=1 and the modulation symbol of d (0)=-1, and NACK corresponds to wherein b (0)=0 and the modulation symbol of d (0)=1.Meanwhile, launch for SPS as UE and ' when there is the ACK/NACK response of the PDSCH ' of PDCCH, can confirm to launch the resource that the ACK/NACK for SPS responds thereon in table 16.Now description is used in table 16 situation ' ACK, NACK/DTX ' and ' NACK, NACK/DTX '.' ACK, NACK/DTX ' corresponds to wherein b (0) b (1)=11 and the modulation symbol of d (0)=1, and ' NACK, NACK/DTX ' corresponds to the modulation symbol of wherein b (0) b (1)=00 and d (0)=1.In a word, the transmitting responded at the ACK/NACK only for SPS and for SPS with ' have in the transmitting of ACK/NACK response of the PDSCH ' of PDCCH, use is transmitted in by identical modulation symbol (that is, for the d (0)=-1 of ACK and the d (0)=1 for NACK) aCK/NACK launch in the ACK/NACK for SPS respond.Therefore, BS can detect on signal time confirm at least the ACK/NACK of SPS respond, and respond with the BS ACK/NACK whether received for SPS or for SPS with ' ACK/NACK with the PDSCH ' of PDCCH responds and has nothing to do.

Meanwhile, the situation of ' ACK, ACK ' in table 16, with in the situation of ' NACK/DTX, ACK ', can use from ' corresponding to the extractive resource of CCE rope of the PDCCH ' of PDSCH, that is, using launch ACK/NACK response.Receiving on signal time, BS can confirm to receive for ' not having the SPS ' of PDCCH and ' have the ACK/NACK response of the PDSCH ' of PDCCH.

In the above example, although conveniently describe PUCCH format 1a, same principle of the present invention can be applied to PUCCH format 1b.

Such as, PUCCH format 1b can be used launch ' only ' to respond for the ACK/NACK of the SPS with two code words.Meanwhile, ' when there is the PDSCH ' of PDCCH, can bundle according to example usage space according to the present invention when receiving together with SPS.In two kinds of situations above, launch the ACK/NACK information for SPS by same channel (PUCCH resource) and modulation symbol.More specifically, by application space binding (such as, logic product), ACK/ACK, ACK/NACK, NACK/ACK and NACK/NACK for two code words of SPS become ACK, NACK, NACK and NACK.If launch for SPS and ' there is the ACK/NACK response of the PDSCH ' of PDCCH simultaneously, ACK/NACK response then for SPS becomes ACK or NACK according to space binding result, and response is identical with ACK/NACK with NACK/NACK of modulation symbol with the channel for responding the ACK/NACK of only SP respectively.Therefore, signal is being detected time, BS can according at least for SPS previous signals (such as, b (0)) be whether ACK or NACK and be space binding result by ACK/NACK response confirmation, and respond with the BS ACK/NACK whether received for SPS or for SPS with ' ACK/NACK with the PDSCH ' of PDCCH responds and has nothing to do.

The emission mode that can be applied equally to wherein in each community of constellation mapping is above situation and other situations of MIMO mode.Also can apply constellation mapping, and with whether in fact application space bundle irrelevant (that is, with whether exist 2 code words launches have nothing to do).

In Application Example 8-3, even can launch application space binding to ' only ' for there is no the ACK/NACK feedback of the SPS of PDCCH.Make comparisons with embodiment 8-1 or 8-2, this situation can reduce the quantity that wherein should be performed the region of blind Detecting by BS.More specifically, in the channel selection profile of definition in LTE version 8, the channel selection profile for the M be worth greatly is made up of the superset of the channel selection profile of the M for little value.Such as, the transmitting of the previous Bit (such as, b (0)) in the Channel assignment of M=2 or only ACK/NACK has and the result using the transmitting of 1 bit ACK of PUCCH format 1a/NACK identical when not applying Channel assignment.Therefore, when by being used as the first resource index for Channel assignment for the SPS PUCCH format 1a/1b resource index activated indicated by PDCCH of the ACK/NACK for ' only ' SPS, the situation of Channel assignment can being used wherein and wherein do not use between the situation of Channel assignment and distinguishing.In this case, detect the ACK/NACK response ' do not have the SPS ' of PDCCH and ' to the PDSCH ' of PDCCH, automatically detect ' only ' and the ACK/NACK of SPS is responded.Therefore, BS can perform blind Detecting in two regions, and (comprising ' only ' to detect for the ACK/NACK of SPS) is detected and for the ACK/NACK detection in PUCCH format 3 for the ACK/NACK in the PUCCH format 1a/1b resource for Channel assignment in these two regions.

Below, the detailed applications example of embodiment 8-3 will be described.

embodiment 8-3-1

As mentioned above, ACK/NACK response is produced about three kinds of situations.Situation 1 relates to the PDSCH with corresponding PDCCH, and situation 2 relates to the PDCCH being used to indicate DLSPS release, and situation 3 relates to the PDSCH not having corresponding PDCCH.Situation 3 is also referred to as the ACK/NACK for SPSPDSCH.

In the explanation of the present embodiment, ' PDCCH ' for ACK/NACK response indicates situation 1 or situation 2, ' SPSPDSCH ' indicates situation 3, and the particular UE DL performed for three kinds of situations above receives and the operation performing the ACK/NACK received for DL is described.The ACK/NACK response of launching in the n-th UL subframe has in the n-th-k subframe about relation (wherein, the k ∈ K, and K:{k that three kinds of situations above respond for the ACK/NACK that DL launches ₀, k ₁... k _m-1, and reference table 12).The explanation of ACK/NACK transmitting subframe position will be omitted below.

In this embodiment, not reducing performance to support the dynamic transmit power that caused by TPC command, (in LTE version 8 or version 10 definition) the predefine channel selection profile by PUCCH format 1a can be used.

First the situation wherein configuring a Serving cell is described now.

In this case, the use of TPC field is determined as follows.

2 bit TPC fields in the PDCCH of DLDAI=1 are wherein used for the TPC command of original object.

2 bit TPC fields in PDCCH in DLDAI>1 are used for ARI object.UE supposes, in all PDCCH wherein in DLDAI>1, ARI value is identical.

In addition, the use of PUCCH format is determined as follows.

If UE only receives SPSPDSCH, then use LTE version 8PUCCH form 1a/1b resource (that is, the operation in fall-back mode).

If UE receives a PDCCH of wherein DLDAI=1, then use LTE version 8PUCCH form 1a/1b resource (that is, the operation in fall-back mode).

If UE receives SPSPDSCH and has another PDCCH of DLDAI=1, then use the predefine channel selection profile (channel selection profile of definition in LTE version 8 and version 10) by PUCCH format 1a.At this, configured by higher level and determine the first PUCCH resource (such as, the resource indicated by the ARI of SPSPDCCH by the resource set that configures at RRC), and determine the second PUCCH resource based on the numbering (or index) of a CCE of the transmitting of the PDCCH PDCCH of DLDAI=1 (that is, wherein) for correspondence.

In other cases, PUCCH format 3 is used as the PUCCH format of configuration.

Meanwhile, present description wherein configures the situation of multiple Serving cell.

At this, the use of TPC field is determined as follows.

Wherein only on PCell DLDAI=1 PDCCH in 2 bit TPC fields be used for the TPC command of original object.

The 2 bit TPC fields of the every other one or more PDCCH on PCell and one or more SCell are used for the TPC command of original object.In all one or more PDCCH of UE supposition on PCell and one or more SCell, ARI value is identical.

In addition, the use of PUCCH format is determined as follows.

If UE only receives another PDCCH of SPSPDSCH and wherein DLDAI=1 on PCell, then use the predefine channel selection profile (channel selection profile of definition in LTE version 8 or version 10) by PUCCH format 1a.At this, by higher level configuration (such as, resource (see table 14) by indicated by the ARI that activated PDCCH in the resource set that configures at RRC by SPS) determine the first PUCCH resource, and, numbering (or index) based on a CCE of the transmitting of the PDCCH PDCCH of DLDAI=1 (that is, wherein) for correspondence determines the second PUCCH resource.

In other cases, PUCCH format 3 is used as the PUCCH format of configuration.

embodiment 8-3-2

In the explanation of the present embodiment, respond relevant ' PDCCH ' to ACK/NACK and indicate situation 1 or situation 2, and ' SPSPDSCH ' indicates situation 3, as described in superincumbent embodiment 8-3-1.The DLDAI indicated by PDCCH that the PDSCH ' that the term PDSCH ' of DAI=1 ' have or ' has DLDAI>1 refers to by corresponding to PDSCH is 1 or is greater than 1.The explanation of ACK/NACK transmitting subframe position will be omitted below.

If UE receives SPSPDSCH and has the PDCCH of DLDAI=1, then because do not have ARI information, so UE can not know available PUCCH resource.In order to solve this problem, method below can be considered.

First the situation of the Channel assignment of the M=2 be wherein used in LTE version 8 is described now.

If UE only receives SPSPDSCH and has the PDSCH of DLDAI=1 and do not receive the PDSCH with DLDAI>1, then UE launches ACK/NACK by the TDD Channel assignment of the M=2 in LTE version 8 while for the binding of PDSCH application space.When using LTE version 8TDD Channel assignment, UE launches two ACK/NACK bits.At this, Channel assignment mapping relations in LTE version 8 can be used in (such as, table 5 is above to 7) and one of Channel assignment mapping relations (such as, table 8 is above to 11) in LTE version 10, and this can be configured by RRC and determines.

In application LTE version 8 Channel assignment, determined by SPSPUCCH resource (that is, the SPS of the resource set configured by higher level activates the resource indicated by PDCCH, see table 14) value.In addition, HARQ-ACK (0) is the ACK/NACK/DTX response of launching for SPSPDSCH.This has the ambiguity of the situation of the PDSCH of DAI=1 to solve wherein UE loss and can launch the ACK/NACK response of launching for SPS definitely.

In this case, in fact the TPC field with the PDCCH of DLDAI=1 can control for PUCCH power.But supporting in the community that MIMO launches (or 2 code words are launched), the loss of ACK/NACK bit may occur due to the space binding of the PDSCH for having DAI=1.

Meanwhile, the situation wherein using PUCCH format 3 can be considered.

If UE receives SPSPDSCH and has the PDSCH of DLDAI=1, then UE can suppose that the TPC field of the PDCCH with DLDAI=1 is for ARI object.Then, UE can use PUCCH format 3 to launch 2 bit ACK/NACK (on non-MIMO community) or 3 bit ACK/NACK (on MIMO community).

In this case, because do not apply ACK/NACK binding, so ACK/NACK bit can be launched, and the loss of ACK/NACK information is not had.Meanwhile, because there is not the TPC field (because the TPC field of PDCCH with DLDAI=1 is for ARI object) for original TPC command object, control so PUCCH power may be performed improperly.

Consider this situation, the two kinds of methods proposed below come in CA for the Resourse Distribute of TDDPUCCH form 3.

First method is in CA, reuse the Resourse Distribute for FDDPUCCH form 3.In this case, the one or more TPC fields on PCell may be used for original object, and the one or more TPC fields on one or more SCell may be used for ARI object.If UE only receives PDSCH on PCell, then can be used in the ACK/NACK binding of definition in LTE version 8.

Second method be when not supporting CA (that is, in non-CA) reuse Resourse Distribute for TDDPUCCH form 3.So, the TPC field with the PDCCH of DAI=1 on PCell may be used for original object, and the TPC field of every other PDCCH on PCell and SCell may be used for ARI object.When UE only receives SPSPDSCH on PCell or have the PDCCH of DLDAI=1, LTE version 8PUCCH form 1a/1b (that is, fall-back mode operation) can be used.When UE receives SPSPDSCH and have the PDSCH of DLDAI=1 but do not receive the PDSCH with DLDAI>1, use LTE version 8 Channel assignment.

launched by the ACK/NACK of PUCCH in a tdd system

Be described in the ACK/NACK binding method in LTE-A (or LTE version 1) and resource allocation methods.

For the ACK/NACK feedback using PUCCH format 3 in TDD, defining mode 1 and pattern 2.Pattern 1 can support until the ACK/NACK payload size of 20 bits.If the quantity of indicated ACK/NACK bit is more than 20, then usage space binding.If the quantity of the ACK/NACK bit indicated in mode 1 is less than 20, then do not support binding.Meanwhile, pattern 2 be wherein bundle with space together with applying portion binding (binding in the time domain or the binding in CC territory) scheme.That is, in mode 2, if the quantity of indicated ACK/NACK bit is more than x, then bundlees with part and side by side perform space and bundle.

When to the ACK/NACK feedback application Channel assignment using PUCCH format 1b in TDD, define pattern a and pattern b.Pattern a is the scheme wherein not supporting any binding when the quantity of indicated ACK/NACK bit is less than 4.Pattern b be wherein bundle with space when the quantity of indicated ACK/NACK bit is more than 4 together with applying portion binding (binding in the time domain or the binding in CC territory) scheme.

On the other hand, the Resourse Distribute for PUCCH format 3 is defined as foloows.2 bit TPC fields in the PDCCH corresponding with PDSCH on PCell are used for the TPC command of original object.The 2 bit TPC fields of the PDCCH corresponding with PDSCH on SCell are used for ARI object.If the PDCCH corresponding with PDSCH do not received on SCell and receive the PDSCH on PCell, then use PUCCH1a/1b by the scheme of definition in LTE version 8.

Below, by describe when only exist on PCell DL receive time ACK/NACK binding method and resource allocation methods.

embodiment 9

Embodiment 9 relates to space binding in mode 1.

Pattern 1 for TDD can be supported until the independent ACK/NACK of 20 bits launches.But, if the quantity of indicated ACK/NACK bit is more than 20, then need application space to bundle.Because the uncertain feedback independently ACK/NACK information when application space bundlees, so the efficiency of HARQ operation may be reduced, and therefore, need maximally to launch independent ACK/NACK information, and do not bundle.That is, space binding is less desirable to the simple application of all ACK/NACK bits in DL throughput performance.And, because pattern 1 is in the scheme not having to launch when changing independently ACK/NACK feedback, so should minimally application space binding.Therefore, need to perform space binding, make the quantity of ACK/NACK bit closest to 20 but be less than 20.

The method detailed being used for when the quantity of indicated ACK/NACK bit is more than 20 performing space binding will be described below.

As the first method, the space binding of in units of CC (one by one CC) can be considered.According to the first method, can application space binding in all DL subframes in a specific CC.By this way, all subframes can be run through about other CC and perform space binding, until want the quantity of the ACK/NACK bit of actual transmission to be less than 20.Assuming that frequently dispatch PCell relative to SCell, can finally application space binding on PCell.

When (namely TDD is configured to 9DL:1UL, the configuration being used for the ACK/NACK that the DL in 9 DL subframes is launched is launched in a UL subframe, such as, subframe 2 see the UL-DL configuration 5 of table 12) time, if the quantity of the CC of configuration is more than 2, even if then space binding is applied to all CC, ACK/NACK payload size is also more than 20 bits.Therefore, when the quantity of the CC configured is 2, can bundle to all CC application spaces.

When TDD configuration is not 9DL:1UL, to beginning from there is at logic index the CC of last index (or the highest index), (the N of code word with two configurations _{configuredDLsubframe}+ N _{cW_SF}-9) individual CC application space binding.Can the most backward PCell application space binding (that is, minimum logic index can be assigned to PCell).At this, N _{configuredDLsubframe}the quantity of the DL subframe of wherein feeding back ACK/NACK on a CC.N _{cW_SF}the sum of code word, for these code words, on all DLCC in a subframe feeding back ACK/NACK.That is, N can be determined as shown in equation 2 _{cW_SF}.

[equation 2]

N_{C W_S F} = Σ_{i = 0}^{N_{c o n f i g u r e d C C s} - 1} N_{C W, i}

In equation 2, N _{cW, i}the quantity of the code word configured on i-th CC.

As the second method, the space binding of in units of subframe (one by one subframe) can be considered.According to the second method, can application space binding on all CC in a specific DL subframe.By this way, all CC can be run through about other DL subframes and perform space binding, until want the quantity of the ACK/NACK bit of actual transmission to be less than 20.

According to the above-mentioned first or second method, the quantity of the ACK/NACK bit of binding is 18,19 or 20.According to the quantity of the CC configured for UE, the quantity of the ACK/NACK bit when application first or the second method is shown below in table 17.

[table 17]

First method maximally can be supported to launch for the independent ACK/NACK of PCell relative to the second method, and can be easily expressed.If the quantity of indicated ACK/NACK bit is more than 20, then preferably, CC ground performs space binding (that is, applying the first method) one by one.

Embodiment 10

In embodiment 10, above-mentioned pattern 2 and the detailed applications example of pattern b are described.Pattern 2 is that together with wherein bundling with the space for using the ACK/NACK of PUCCH format 3 in TDD to feed back, applying portion bundlees the scheme of (binding in the time domain or the binding in CC territory).Pattern b is that together with wherein bundling with the space that the ACK/NACK for using PUCCH format 1b in TDD feeds back when applying Channel assignment when the quantity of indicated ACK/NACK bit is more than 4, applying portion bundlees the scheme of (binding in the time domain or the binding in CC territory).

Pattern 2 can be used to the ACK/NACK performance improved about the UE of power limited valuably.When supporting until FDD and the support of the ACK/NACK of 10 bits are until when the TDD of ACK/NACK of 20 bits makes comparisons, TDD has the UL covering less than FDD.In addition, when the quantity of DLCC in configuring at TDD9DL-1UL is more than 2, pattern 1 (wherein, the application space binding when the quantity of indicated ACK/NACK bit is more than 20, and when the quantity of indicated ACK/NACK bit be 20 or less time not application space bundle) can not support that ACK/NACK feeds back.Such as, in order to be supported in the ACK/NACK feedback on 5 DLCC and in TDD9DL-1UL configuration, need 45 ACK/NACK bits altogether, even if application space binding.Therefore, in order at least support that ACK/NACK feeds back in TDD9DL-1UL configuration, the above-mentioned pattern 2 supporting to be used for PUCCH format 3 is needed.

Below, the space binding to pattern 2 and pattern b application will be described in detail.

embodiment 10-1

In embodiment 10-1, describe space binding in the time domain.Except the binding of space, also can perform time domain binding in this embodiment.

The time domain binding as space binding can be performed, and be not modified in 2 bit DAI of the definition in LTE version 8 on each CC in addition.And, in the binding of application time domain, on each CC, time domain binding can be applied simply, and various forms of CA need not be considered.That is, the time domain binding method determining the various situations of CA is that it is enough.Because be 10 bits as the size of the ACK/NACK information bit of the application result of time domain binding, so PUCCH format 3 structure of LTE version 10 can be used as the PUCCH format that will be used for ACK/NACK transmitting.

PDCCH about all distribution sequentially increases DAI value.Therefore, when using DAI, UE can not be identified in the situation of losing last PDCCH in time domain bundled window.In order to solve this problem, the DAI value for the PDCCH of the last detection on each CC can be imported into ACK/NACK mapper, and is then encoded.

Figure 40 is the figure of illustrative exemplary domain portion binding.In the example of Figure 40,4 subframes on each CC are applied ACK/NACK binding.

In a CC of Figure 40, UE has received the PDCCH with DAI=0 in the first subframe and the PDCCH with DAI=1 in the second subframe, but does not also receive the PDCCH with DAI=2 in the 3rd subframe.Then, because UE does not know whether to transmit last PDCCH (DAI=2), UE can identify all PDCCH received in time domain bundled window.In addition, Figure 40 illustrates following situation, and wherein, successfully each of the PDSCH of the PDCCH scheduling received is passed through in decoding (that is, ACK), and as a result, produces ACK as the ACK/NACK information bundled.Together with produced ACK information, UE can encode last received DAI value, that is, DAI=1.UE coding and transmitting ACK and DAI (DAI=1), and then, BS can identify that UE have lost PDCCH (DAI=2).

The time domain bundling operation on the 2nd CC of Figure 40 is similar on a CC.Last received DAI value (that is, DAI=0) can be encoded by UE together with ACK information.Because UE encodes and launches ACK and DAI (DAI=0), so BS can identify that UE have lost PDCCH (DAI=1).

In the 3rd CC of Figure 40, UE receives the PDCCH (DAI=0) in the first subframe, and receives the PDCCH (DAI=2) in the 3rd subframe.Even if UE unidentified go out the transmitting of PDCCH (DAI=1) in the second subframe, UE can identify itself and have lost PDCCH (DAI=1), because the DAI value of the PDCCH received sequentially does not increase.Although Figure 40 illustrates the situation of each of the PDSCH that wherein successfully decode (that is, ACK) is dispatched by received PDCCH, UE may produce the ACK/NACK information of NACK as binding, because have lost the transmitting of a PDCCH.

In the 4th CC of Figure 40, UE only receives PDCCH (DAI=0), and produces ACK information when successfully decoding the PDSCH dispatched by PDCCH.Produced ACK information can be encoded together with last received DAI value (DAI=0).

In the 5th CC of Figure 40, UE only receives the PDCCH with DAI=0.UE does not know in the 4th subframe, to transmit the PDCCH with DAI=1.Figure 40 illustrates the PDSCH that decode (that is, NACK) is dispatched by the PDCCH received by UE wherein unsuccessfully.Therefore, UE can produce nack message.

Therefore, when applicable domain space binding time, can reuse on each CC LTE version 82 bit TDDDAI (that is, as PDCCH stored counts device) and without the need to amendment.

As the example of the PUCCH format 3 of the application for pattern 2, can as being defined in the ACK/NACK state of each CC before chnnel coding as shown in table 18.

[table 18]

Use the ACK/NACK state of table 18, be expressed as follows by the result of the ACK/NACK of binding encoded together with the DAI value of the last received PDCCH on each CC in Figure 40: ' 01 (DAI=1) ' on a CC, ' 01 (DAI=0) ' on the 2nd CC, ' 11 (NACK) ' on the 3rd CC, ' 00 (DAI=0) ' on the 4th CC and ' 11 (NACK) ' on the 5th CC.

The polymerization of the ACK/NACK payload for 5 CC perform chnnel coding in the PUCCH format 3 that pattern 2 is applied to before is ' 0100110011 '.

Principle of the present invention for above-mentioned pattern 2 can be applied equally to pattern b.For the application of pattern b, the relation between Channel assignment mapping relations (mapping relations between PUCCH resource and ACK/NACK bit) and NACK/DAI value can be defined in.

Therefore, when deployed during the binding of territory, each ACK/NACK response on each CC can be expressed as binding ACK/NACK information.

embodiment 10-2

In embodiment 10-2, describe the binding of CC domain space.Except the binding of space, time domain binding in this embodiment can be performed.

In the binding of CC territory, preferably, the designator of the sum of the PDSCH (or PDCCH of correspondence) using DAI to dispatch in the bundled window be made up of multiple CC in a subframe as instruction, instead of use DAI as the stored counts device of the PDSCH dispatched in multiple subframe on each CC (or PDCCH of correspondence) as in conventional DAI.This is because when DAI indicates the PDSCH of each subframe (or PDCCH) total, wherein UE need not be provided for and abandons the solution of the situation of last PDCCH in time.

Then, UE can work as transmitting ACK when quantity that the DL that decodes for success in bundled window launches the ACK produced equals in bundled window PDSCH (or PDCCH) total, and otherwise UE launches NACK (now, DTX being expressed as NACK).

Below, detailed description CC territory is bundled the application to pattern b and pattern 2.

Be described with reference to Figure 41 the Channel assignment for bundling to pattern b application CC territory.

In this case, the Channel assignment mapping relations of general hypothesis application LTE version 10 (such as, table 8 to 11) above.

If (namely use implicitly determines, draw from the CCE index of PDCCH) ACK/NACKPUCCH resource, then can first select in each subframe with for the PUCCH resource of the PDCCH dynamic link of the scheduling on PCC (or PCell).

If only dispatch PDSCH on PCC (or PCell) in many CC configuration, then can be applied in ACK/NACK resource mapping in LTE version 8 (such as, table 5 to 7) above.That is, the operation of the fall-back mode in LTE version 8 can be performed.

In the example of Figure 41, assuming that configure Liang Ge community (PCC and SCell) in each subframe.

In the TDD2DL:1UL configuration of Figure 41, in the first subframe, because PDSCH is not scheduled and is scheduled on SCC on PCC, so from the CCE index determination PUCCH resource of the PDCCH for dispatching SCCPDSCH.In the second subframe, can from the CCE index determination PUCCH resource of the PDCCH for dispatching PCCPDSCH.Such PUCCH resource can be used to use channel selection operations.Such as, Channel assignment mapping relations as shown in table 8 can be used to launch to perform ACK/NACK.

In TDD3DL:1UL configuration, in all subframes, only on PCC, dispatch PDSCH.In this case, fall-back mode operation can be performed as mentioned above.Such as, Channel assignment mapping relations as shown in Table 6 can be used to perform ACK/NACK by PUCCH format 1b launch.

In TDD4DL:1UL configuration, because dispatch PDSCH in the first subframe on PCC and SCC, so PUCCH resource can be determined based on the CCE index of the PDCCH for dispatching the PDSCH on PCC.Because PDSCH is not scheduled and be only scheduled on a community (PCC or SCC) in the third and fourth subframe in the second subframe, PUCCH resource can be determined based on the CCE index of the PDCCH of the PDSCH of correspondence.By this way, determined PUCCH resource can be used to perform channel selection operations.Such as, the Channel assignment mapping relations shown in table 10 can be used in launch to perform ACK/NACK.

The example applying the binding of CC territory to pattern 2 is described with reference to Figure 42.

In the example of Figure 42, assuming that the maximum quantity of ACK/NACK bit is 12, and maximum bundled window was 2 (that is, comprising maximum two CC a bundled window).

In order to keep independently ACK/NACK to launch, application bundle gradually, until the quantity of ACK/NACK bit is less than 12 closest to 12.

In addition, in bundled window, PCell (or PCC) is not comprised.That is, only bundled window is configured for SCell (SCC).Application bundle window can be carried out with the ascending order of CC index.

As shown in Figure 42, the binding of CC territory can little by little application bundle window (being made up of 2 CC), until the quantity of ACK/NACK bit (quantity of the ACK/NACK bit after the binding of application space) becomes 12 or less.

In the 2DL:1UL configuration of Figure 42, because the quantity of the ACK/NACK bit after performing space binding is 10, so do not configure bundled window.

In 3DL:1UL configuration, because the quantity of the ACK/NACK bit after performing space binding is 15, so configuration bundled window.The quantity of the ACK/NACK bit after the bundled window being configured for two CC (SCC3 and SCC4) is 12, and therefore, no longer configures bundled window.

In the 4DL:1UL configuration of Figure 42, because the quantity of the ACK/NACK bit after performing space binding is 20, so configuration bundled window.When being configured for the bundled window of two CC (SCC3 and SCC4), produce 16 bit ACK/NACK, and therefore, configure another bundled window.If configure another bundled window for two CC (SCC1 and SCC2), then produce 12 bit ACK/NACK, and therefore, no longer configure bundled window.

Therefore, when using the part binding of CC territory, the binding result (such as, the result of logic and operation) for all ACK/NACK bits in bundled window is launched as ACK/NACK information.DAI in PDCCH indicates the sum of the PDSCH dispatched on all CC in a subframe.The largest amount of the bundled window being used for PUCCH format 3 can be defined as 2 (that is, maximum two CC (or community) can configure a bundled window).

embodiment 11

Embodiment 11 relates to when only receiving PDCCH/PDSCH on PCell (receiving hereinafter referred to as only PCell) by the ACK/NACK launching technique of PUCCH format 3.Especially, the only PCell be described in detail in TDD receives.

When not receiving on SCell and only receive the PDCCH corresponding to PDSCH on PCell, the PUCCH format 1a/1b resource of LTE version 8 (that is, can run in fall-back mode) can be used.

In fdd, fall-back mode can be applied for being used in the object of the PUCCH resource defined in LTE version 8 and determining the object of PUCCH resource clearly, even if do not receive ARI on SCell.

If TPC field is for the ARI object on SCell, then ACK/NACK resource may be fuzzy under only PCell reception condition.In order to solve this problem, the ACK/NACK defined in LTE version 8TDD system multiplexing or ACK/NACK binding can be applied in.But, if application ACK/NACK binding or time domain binding, then can not launch some ACK/NACK information, and therefore, the considerable damage of DL throughput may be produced.And, because carry out lap ACK/NACK state with ACK/NACK mapping relations, so the ACK/NACK performance of the 4 bit ACK/NACK in LTE version 8TDD system can not be ensured.

Therefore, set forth below is the ACK/NACK launching technique for only PCell reception condition.

embodiment 11-1

According to this embodiment, when receiving single PDSCH on PCell, the resource of the PUCCH format 1a/1b of definition in LTE version 8 can be used in.In this case, the use of DAI and ARI can be defined as follows.

Figure 43 is the figure of the example of the use of diagram DAI and TPC.

As shown in Figure 43, as in LTE version 8TDD system, the DAI on PCell can be used as the stored counts device of PDCCH (or PDSCH).As in LTE version 8TDD system, the DAI on SCell can be used as the stored counts device of PDCCH (or PDSCH).DAI on SCell can be configured to ' 00 '.In the examples shown of Figure 43, the DAI value of the PDCCH of SCell is all configured to ' 00 '.If the DAI value of the PDCCH on SCell is configured identically as ' 00 ', then also imperial edict can dispatch PDCCHDCI in public search space.In UE realizes, predefine value ' 00 ' can be used as virtual CRC (that is, for the error detection when DAI value is not ' 00 ').

As shown in Figure 43, the TPC field of the PDCCH (that is, having the PDCCH of DAI=00) first PCell distributed is used for the TPC command of original object.The TPC field of the every other PDCCH (comprising PCell and SCell) except the PDCCH with DAI=00 on PCell is used for ARI object, and the field for ARI object in PDCCH should have identical value in all PDCCH.

UE behavior in this case can be defined as foloows.

the PDSCH of corresponding PDCCH is not had to launch (that is, only SPSPDSCH) if existed on PCell,

If √ does not have other PDSCH to launch,

● use LTE version 8PUCCH form 1a/1b.

√ otherwise,

● use PUCCH format 3.

-exceptionally, the TPC field in the PDCCH with DAI=' 00 ' is used as ARI.

otherwise

If there is the single PDSCH with DAI=' 00 ' or there is the single PDSCH with DAI=' 00 ' being used to indicate DLSPS release on PCell in √ on PCell,

● use LTE version 8PUCCH form 1a/1b

√ otherwise,

● use PUCCH format 3.

In superincumbent explanation, wherein the situation of ' existence does not have the PDSCH of corresponding PDCCH to launch ' corresponds to DLSPSPDSCH.And ' the DAI field of single PDSCH ' instruction in the PDCCH corresponding to PDSCH with DAI=' 00 ' is 00.

Embodiment 11-1 is applicable to comprise all situations that the 9DL:1UL sub-frame configuration for TDDACK/NACK feedback bundlees with the time domain/CC territory for pattern 1 and pattern 2.

The above embodiments 11-1 is gathered as follows.

Use the resource of LTE version 8PUCCH form 1a/1b and PUCCH format 1a/1b in the following cases: (1) wherein exists on PCell ' does not have the situation of the single PDSCH ' of corresponding PDCCH, (2) wherein only exist on PCell ' there is the corresponding single PDSCH ' of PDCCH and the DAI value in PDCCH be 00 situation, or (3) wherein only exist on PCell, and ' the single PDCCH ' that instruction DLSPS discharges and DAI value in PDCCH are the situations of 00.

LTE version 8PUCCH form 3 is for the situation except (1), (2) and (3) situation above.

' there is no the PDSCH (that is, DLSPSPDSCH) ' of corresponding PDCCH if do not existed on PCell, then perform operation below.If existed on PCell, ' have the corresponding PDSCH ' of PDCCH and the DAI value of PDCCH is 00, then the TPC field of PDCCH is used for the TPC command of reality.If existed, ' PDCCH ' of instruction DLSPS release and the DAI value of PDCCH is 00, then the TPC field of PDCCH is for actual TPC command.In other cases, all TPC fields are used as ARI.

In other cases (that is, PCell exists ' PDSCH (that is, DLSPSPDSCH) ' not having corresponding PDCCH), all TPC fields of PDCCH are used as ARI.

In addition, above all, all fields being used as ARI in PDCCH have identical value.

embodiment 11-2

In fdd, the TPC field on SCell is used for ARI object, and the TPC field on PCell is used for original TPC object.According to this embodiment, in TDD, with mode similar in fdd, the TPC field in the PDCCH on PCell is used for original TPC object, and the TPC field in PDCCH on SCell is used for ARI object.In this case, the PUCCH power control operation identical with the operation in traditional LTE version 8 can be performed and without the need to revising.

Figure 44 is the figure of another example of the use of diagram DAI and TPC.

As in the example of Figure 44, the DAI field about the UE only receiving PDSCH on PCell, the PDCCH on PCell may be used for ARI object.Such DAI field is used to be available in mode 1, because pattern 1 need not be supported in the DAI in time domain/CC territory binding.In addition, the field (the DAI field on PCell and the TPC field on SCell) being used as the ARI of PDCCH should have identical value.

In the examples shown of Figure 44, the DAI value of the PDCCH on SCell is all configured to ' 00 '.The description thereof will be omitted, because it is identical with the explanation of Figure 43.

UE behavior based on explanation is above defined as foloows.

Embodiment 9 to 11 above relates generally to the detailed applications example of the present invention of launching for the ACK/NACK in a tdd system by PUCCH.

embodiment 12

In this embodiment 12, be described on PCell and ' in the PDCCH ' of instruction DLSPS release, using the method for ARI.

Specifically, embodiment 12 relates to a kind of for there is not PDSCH and there is SPSPDSCH (namely on PCell on one or more SCell, there is no the PDSCH of corresponding PDCCH) when, when be received on PCell single ' instruction DLSPS release PDCCH ' time, by reusing, ' the TPC field of the PDCCH ' of instruction DLSPS release, launches the method for ACK/NACK via PUCCH format 3.That is, the method for ACK/NACK is launched when having described for SPSPDSCH (that is, there is not the PDSCH of corresponding PDCCH) ought not be there is and receive single PDSCH on PCell.In this embodiment, ought not there is PDSCH (that is, having/do not have the PDSCH of corresponding PDCCH) and on PCell, receive ' the another kind of ACK/NACK launching technique during PDCCH ' that instruction DLSPS discharges in description.

A kind of method of ARI that uses in fdd is as follows.

On PCell ' instruction DLSPS release PDCCH ' TPC field be used for ARI object.PCell uses except ' the TPC field of the PDCCH except the PDCCH ' of instruction DLSPS release carrys out the TPC command for original object.And the TPC field of the PDCCH on SCell is used as ARI.The all ARI values of UE supposition on PCell and SCell are identical.

● when there is not corresponding PDCCH, can by corresponding to the TPC field of the PDCCH of SPS or selecting PUCCH resource (explicit mapping) by the value of the TPC field in PDCCH from the resource that RRC configures between SPS active period.

● when there is corresponding PDCCH, PUCCH resource (implicit expression mapping) can be selected by the regulation rule (such as, by the equation of definition in LTE version 8) based on the CCE index of PDCCH.

otherwise, if only there is the single PDCCH (that is, only SPS discharges PDCCH) of instruction DLSPS release on PCell.

√ uses PUCCH format 3.

The TPC field of the PDCCH of instruction DLSPS release exceptionally, also can be used as ARI by √.

otherwise,

√ uses PUCCH format 3.

Next, in TDD, use the method for DAI and ARI as follows.

As in LTE version 8, the DAI on PCell is used as the stored counts device of PDCCH/PDSCH.DAI for SCell is configured to preset value (such as, ' 00 '), makes to dispatch DCI on public search space.In UE realizes, this preset value can be used as virtual CRC.

The TPC field of the PDCCH (that is, having the PDCCH of DAI=1 or DAI=00) that first PCell distributes is used for the TPC command of original object.The TPC field of the every other PDCCH (that is, other PDCCH on PCell and the PDCCH on SCell) except the PDCCH first distributed on PCell is used for ARI object.TPC field in other PDCCH superincumbent as DAI=' 00 ' is also used as ARI.In addition, UE supposes that all ARI values are identical.

embodiment 13

Embodiment 13 relates to a kind of basis and whether there is the method that SPSPDSCH uses different TPC fields.

As mentioned above, ACK/NACK response is produced about three kinds of situations.Situation 1 relates to the PDSCH with corresponding PDCCH, and situation 2 relates to the PDCCH of instruction DLSPS release, and situation 3 relates to the PDSCH not having corresponding PDCCH.Situation 3 is also referred to as the ACK/NACK for SPSPDSCH.

In the explanation of this embodiment, situation 1 or situation 2 is indicated for responding relevant ' PDCCH ' to ACK/NACK, ' SPSPDSCH ' indicates situation 3, and the DL that particular UE performs the three kinds of situations above that are used for receives and performs the operation of ACK/NACK received for DL and is described.The ACK/NACK response of launching in the n-th UL subframe has at the n-th-k subframe (wherein, k ∈ K and K:{k ₀, k ₁... k _m-1, and see table 12) in the relation of ACK/NACK response that the DL of three kinds of situations is above launched.Below, the explanation of ACK/NACK transmitting subframe position will be omitted.

If launch ACK/NACK by various form from UE, then increase the complexity that BS explains the blind decoding of ACK/NACK.In order to improve the performance in BS, such as complicated blind decoding, and in order to effectively use resource, the PUCCH format configured by higher level can be used.Below, depend on whether there is SPSPDSCH and the method that uses different TPC fields by describing in detail.

When a configuration Serving cell, can the use of (2 bit) TPC field be determined as follows.When there is SPSPDSCH, the TPC field in all PDCCH can be used as ARI, and UE can suppose that ARI value is identical in all PDCCH.Meanwhile, if there is no SPSPDSCH, then the TPC field with the PDCCH of DLDAI=1 may be used for original TPC command, and the TPC field with the PDCCH of DLDAI>1 can be used as ARI.UE can suppose that the ARI value in all PDCCH with DLDAI>1 is identical.

In addition, when a configuration Serving cell, can the use of PUCCH format be determined as follows.If UE ' is only ' receive SPSPDSCH, then can use LTE version 8PUCCH form 1a/1b.Or, if UE ' is only ' and receive the single PDCCH with DLDAI=1, then can use LTE version 8PUCCH form 1a/1b.In other cases, PUCCH format 3 can be used as the PUCCH format configured by higher level.

If DLDAI is used as simple counter (PDCCH stored counts device), then the Resourse Distribute of the TDDPUCCH form 3 in CA can be identical with the Resourse Distribute in single carrier wave (or non-CA).That is, the resource allocation methods for PCell can use the method identical with the resource allocation methods in non-CA.In the case of a ca, can the PUCCH resource distribution for multiple community be determined as follows.

If the use of TPC field more than a Serving cell, then can be determined as follows by configuration.When there is SPSPDSCH, the TPC field of all PDCCH on PCell and one or more SCell can be used for ARI object, and UE can suppose at PCell identical with the ARI value on all PDCCH on one or more SCell.Simultaneously, if there is no SPSPDSCH, the TPC field with the PDCCH of DLDAI=1 then only on PCell may be used for original TPC command, and the TPC field of every other PDCCH on PCell and one or more SCell may be used for ARI object.UE can suppose at PCell identical with the ARI value on all PDCCH on one or more SCell.

If configuration is more than a Serving cell, then the purposes of PUCCH format can be as follows by use.If UE ' is only ' receive SPSPDSCH, then can use LTE version 8PUCCH form 1a/1b.Or, if UE ' is only ' and receive the single PDCCH with DLDAI=1, then can use LTE version 8PUCCH form 1a/1b.For other situations, PUCCH format 3 can be used as the PUCCH format configured by higher level.

embodiment 14

Embodiment 14 relates to PUCCH resource distribution method that consider above-described embodiment, that launch for TDDHARGACK/NACK response.

In traditional LTE version 8/9 system, because to exceeding specified bit size (such as, 4 bits) ACK/NACK launch application ACK/NACK binding (space binding and/or time domain binding), so created the loss of independent ACK/NACK information.In LTE version 10 (or LTE-A) system, design PUCCH format 3 is to support until the transmitting of independent ACK/NACK information of 20 bits.In CA and/or TDD back-up system, because the situation of wherein launching the ACK/NACK of 20 bits or more may occur, so need the method being used for effectively utilizing resource while launching ACK/NACK information without loss.

Figure 45 is the figure of diagram for the example of the present invention of the use of the TPC field in PDCCH.In the example of Figure 45, ARI is the information of the resource of the PUCCH format 3 that instruction is launched for ACK/NACK.Although the TPC field with the PDCCH of DLDAI=1 on PCell is for original TPC command, the TPC field of other PDCCH on PCell and SCell is used as ARI.UE can suppose that the ARI value on PCell with SCell is identical.Therefore, even if an ARI only detected, the resource of PUCCH format 3 can also be determined.

When TPC field being used as again ARI, the precision that PUCCH power controls may be reduced.But, because positively can be determined the resource of PUCCH format 3 by ARI information, so relative to the reduction in the precision controlled at PUCCH power, the transmitting of lossy ACK/NACK information that do not have using PUCCH format 3 may be preferred for whole system.

In the example of Figure 45, when UE comprises success at least one PDCCH of ARI in detection, the PUCCH format 3 indicated by ARI can be used to launch ACK/NACK response.But, if UE ' is only ' detect there is no the PDCCH of ARI (that is, the PDCCH with DAI=1 on PCell), then UE can not obtain ARI information, and can not determine PUCCH format 3 resource.In this case, can use conventional form, namely the PUCCH format 1a/1b of LTE version 8/9 launches ACK/NACK response without information loss.

Therefore, can provide a kind of resource allocation methods, the method can launch the ACK/NACK response of the DL launched in one or more DL subframe being launched to (PDCCH and/or PDSCH) without any loss.In addition, because independently determine PUCCH format and PUCCH resource in the same manner with CA or non-CA, so the operation of BS and UE can be specified simply and clearly.

Figure 46 is the overall flow figure that the various embodiments proposed in the present invention are described.In the example of Figure 46, under prerequisite PUCCH format 3 being configured for UE by higher level, provide explanation.

In step S4610, UE determines whether only to receive on PCell the PDSCH (that is, corresponding to the PDSCH of PDCCH with DAI=1) with DAI=1.

If the result of step S4610 is yes, then perform step S4620.Because the TPC field with the PDCCH of DAI=1 on PCell is for original TPC command, so UE can not obtain ARI information when only receiving the PDCCH with DAI=1.Therefore, UE does not use PUCCH format 3.UE can use PUCCH format 1a/1b to launch ACK/NACK.The resource that (that is, by from the extractive PUCCH resource index of the CCE rope of PDCCH) determines PUCCH format 1a/1b can be mapped by implicit expression.

Meanwhile, if the result of step S4610 is no, then perform step S4630.In step S4630, UE determines whether the single PDSCH not having PDCCH received only on PCell.

If the result of step S4630 is yes, then perform step S4640.Because UE does not also receive PDCCH, so UE can not obtain ARI information, and do not use PUCCH format 3.UE can use PUCCH format 1a/1b to launch ACK/NACK.At this, because also do not receive PDCCH, so UE can not draw from the extractive PUCCH resource index of PDCCHCCE rope.Therefore, UE can determine PUCCH resource index according to activating at SPS information that PDCCH comprises (such as, reusing indicated information by what activate TPC field in PDCCH at SPS).

If the result of step S4630 is no, then perform step S4650.In step S4650, UE determines whether to receive ' having the PDSCH ' of DAI=1 and other ' not having the PDSCH ' of PDCCH only on PCell.

If the result of step S4650 is yes, then perform step S4660.Even if in this case, because ARI information can not be obtained, so UE uses PUCCH format 1a/1b to replace PUCCH format 3.At this, UE can launch ACK/NACK information by channel selection profile, to prevent the loss of ACK/NACK information.Can Channel assignment be performed, make to select PUCCH resource from the individual PUCCH resource of A (=2 or 3).At this, the value of A can be determined according to the quantity of the code word of PDSCH (or transmission block).

Meanwhile, if the result of step S4650 is no, then perform step S4670.In step S4670,1 (namely UE can determine that wherein DAI value is not, whether the value of the ARI (that is, TPC field) of PDCCH DAI>1) equals ARI (that is, the TPC field) value of all PDCCH on one or more SCell.

If the result of step S4670 is yes, then perform step S4680.In this case, UE can use PUCCH format 3 resource indicated by ARI to launch ACK/NACK information.UE supposes that ARI value is identical in all PDCCH, and the ARI value that can be used at least one PDCCH is to perform step S4680.

Meanwhile, if the result of step S4670 is no (if the ARI value that is, on PCell and one or more SCell is unequal), then UE can abandon received PDCCH.

In a word, ' have the PDSCH ' of PDCCH, ' that should launch ACK/NACK to it for UE does not have the PDSCH (SPS-PDSCH) ' of PDCCH and ' SPS discharges PDCCH ', can define UE behavior below.But scope of the present invention is not limited thereto, and can by the available set incompatible execution TDDHARQACK/NACK Resourse Distribute of various embodiment of the present invention and firing operation.

First, the operation of non-CA system can operate identical with ' only PCell receives ' in CA environment.That is, the TDDHARQACK/NACK Resourse Distribute when configuring a Serving cell for UE and firing operation can with when when to configure the TDDHARQACK/NACK Resourse Distribute more than when only receiving PDSCH and/or PDCCH when a Serving cell on PCell identical with firing operation.Therefore, below, when configure only a Serving cell time, the description of the operation on PCell can be replaced with operation on the serving cell.

If the DAI corresponded at PCell in the PDCCH of PDSCH is 1, then TPC field is used for original power control object.If the DAI in the PDCCH corresponding to PDSCH is greater than 1, then TPC field is used as ARI.The TPC field corresponded in the PDCCH of all PDSCH on SCell is used as ARI.UE supposes that all ARI values are identical.

If UE only receives an only SPS-PDSCH on PCell, then UE return back to PUCCH format 1a/1b.

If UE only receives the PDSCH (that is, PDSCH that is corresponding with PDCCH, that have DAI=1) with DAI=1, then UE return back to PUCCH format 1a/1b.

If only receive a PDSCH and SPS-PDSCH with DAI=1 on PCell, then launch by using the channel selection profile of PUCCH format 1b to perform ACK/NACK.Quantity A for the PUCCH resource of Channel assignment is 2 or 3.

If receive one or more PDSCH (PDCCH that is corresponding with PDSCH, that have DAI>1) with DAI>1, then PUCCH format 3 resource indicated by ARI is used to launch to perform ACK/NACK.

If receive one or more PDSCH on SCell, then PUCCH format 3 resource indicated by ARI is used to launch to perform ACK/NACK.

Therefore, ' have the PDSCH ' of PDCCH, ' does not have the PDSCH (SPS-PDSCH) ' of PDCCH and ' SPS discharges all situations of one of PDCCH ', correctly and effectively can launch ACK/NACK information when not losing ACK/NACK information for only receiving at PCell or on PCell and one or more SCell.

Embodiment 15

Embodiment 15 relates to the resource allocation methods for PUCCH format 3.First will describe the situation of a configuration Serving cell and the situation configuring more than one Serving cell will be described after a while.

If be configured with a Serving cell, then can use PUCCH format 3, the Channel assignment of M=2 can be used, or can PUCCH format 1a/1b be used.

When using PUCCH format 3, if there is SPSPDSCH in bundled window, then UE can suppose that the TPC field with DLDAI=1 is also used to ARI purposes.Then, UE can determine PUCCH format 3 resource and PUCCH format 3 can be used to launch ACK/NACK.

When using the Channel assignment of M=2 wherein, following operation can be performed.

If UE receives SPSPDSCH and only has the PDCCH of DLDAI=1 and do not have receiving belt to have the PDCCH of DLDAI>1, then UE can use the Channel assignment of M=2 and launch ACK/NACK for the PDSCH indicated by SPSPDSCH and the ACK/NACK application space binding of the PDCCH with DLDAI=1 simultaneously.The implicit resource of LTE version 8 can be used to distribute (such as, table 5) rule to launch 2 bit ACK/NACK, UE or meet the mapping relations (such as, table 8) of LTE version 10.

Assuming that UE launches ACK/NACK by the channel selection profile of the mapping relations according to LTE version 8, between the situation of PDCCH that there is SPSPDSCH and there is DAI=1 and the situation that only there is SPSPDSCH, or there is SPSPDSCH and having that to carry out difference between the situation of PDCCH of DAI=1 and the situation that only there is the PDCCH with DAI=1 may be indefinite.

In application for the Resourse Distribute of Channel assignment with in head it off, can be determined by the TPC field of the PDCCH activating SPSPDSCH and determined by the CCE index corresponding with PDSCH in addition, HARQ-ACK (0) can be mapped to and respond the ACK/NACK/DTX of the transmission of SPSPDSCH, and HARQ-ACK (1) can be mapped to the ACK/NACK/DTX response to the transmission of the PDSCH with corresponding PDCCH.Then, when UE loss has a PDCCH of DAI=1 to the ACK/NACK response of SPSPDSCH (selected channel and the bit launched in the channel or constellation) can with receive the PDCCH with DAI=1 as UE and respond identical with the ACK/NACK to SPSPDSCH during the PDSCH that the PDCCH with DAI=1 is corresponding in responding the ACK/NACK of SPSPDSCH.That is, BS correctly can be received by the detection of fixing response part (selected channel and the bit launched in the channel or constellation) and respond the ACK/NACK of SPSPDSCH, and whether detects the PDCCH with DAI=1 regardless of UE.

Next, when UE receives SPSPDSCH and only have the PDCCH of DAI=1 and do not have reception to have one or more PDCCH of DLDAI>1, UE can use PUCCH format 1a/1b to launch ACK/NACK.

Under these circumstances, the first PUCCH resource index can derive from the CCE index of the PDCCH corresponding with PDSCH, or can be configured to use the SPSPUCCH resource indicated by the TPC field of SPS activation PDCCH.When usage space orthogonal resource transmit diversity (SORTD), by by the CCE index of offset applications in the PDCCH corresponding with PDSCH, the second PUCCH resource index can be derived from " CCE index+1 " or the second PUCCH resource using SPSPUCCH resource can be configured to.

Meanwhile, more than one Serving cell can be configured, following two kinds of methods can be applied.

As the first method, the Resourse Distribute for FDDPUCCH form 3 can be reused.Under these circumstances, one or more TPC fields of the one or more PDCCH on PCell can be used to original TPC object, and the one or more TPC fields on one or more PDCCH on one or more SCell can be used to ARI object.If UE only receives SPSPDSCH or PDCCH on PCell, then can be used in the ACK/NACK binding of definition in LTE version 8.

As the second method, the Resourse Distribute for TDDPUCCH form 3 in non-CA can be reused.That is, when SPSPDSCH does not exist, the TPC field with the PDCCH of DAI=1 only on PCell can be used to original TPC object, and other the TPC fields of PDCCH all on PCell and SCell can be used to ARI object.On the other hand, if SPSPDSCH exists, then all TPC fields on PCell and one or more SCell also can be used to AIR object.UE can suppose that all AIR have identical value.When UE only receives SPSPDSCH on PCell or have the PDCCH of DLDAI=1, the PUCCH format 1a/1b of definition in LTE version 8 can be used in.When UE only receives SPSPDSCH on PCell and have the PDCCH of DLDAI=1, the channel selecting method being used in one or more PUCCH format 1a/1b of definition in LTE version 8 can be used.

The transmission method of the UCI of two kinds or more of type

In previous embodiment 1 to 15 of the present invention, about under the state configuring PUCCH format 3 for UE with " there is the PDSCH of corresponding PDCCH ", " not there is the PDSCH (SPSPDSCH) of corresponding PDCCH " and describe at CA, non-CA and " DLSPS discharges PDCCH " only in PCell reception condition the various examples that ACK/NACK transmits.

The UCI that UE launches comprises ACK/NACK, SR, CSI etc.CSI can comprise RI, PMI (PMI and the 2nd PMI), CQI etc.In some cases, need to launch ACK/NACK information together with other UIC (SR or SCI), that is, in identical subframe.At this, the situation of wherein being launched ACK/NACK, SR and CSI by PUCCH is described.That is, scope of the present invention is not applied to the situation of ACK/NACK, SR and the CSI that wherein incidentally will be launched on PUSCH.

Hereinafter, will be described in for UE configure PUCCH format 3 state under when launching SR or launch CSI together with ACK/NACK together with ACK/NACK example of the present invention.In other words, the method using suitable PUCCH format simultaneously to launch ACK/NACK and SR or ACK/NACK and CSI (that is, the CSI in cycle) will be described hereinafter.

Embodiment 16

Embodiment 16 relates to the transmission method when two ACK/NACK responses should be launched and need SR to transmit simultaneously.

Under these circumstances, two ACK/NACK responses can be to the response of a SPSPPDSCH and the response to " having the PDSCH of corresponding PDCCH ".Or two ACK/NACK responses can be to the response of a SPSPDSCH and the response to " DLSPS discharges PDCCH ".The DLDAI value of the PDCCH such as, in two responses, " having the PDSCH of corresponding PDCCH " or in " DLSPS discharges PDCCH " can be 1.In addition, an ACK/NACK response in the present invention can correspond to single ACK/NACK response group, and therefore, two ACK/NACK responses can indicate two ACK/NACK responses.

When needs launch two ACK/NACK responses and SR simultaneously, the present invention proposes the transmission being used ACK/NACK response (or an ACK/NACK response group) of PUCCH format 1b and the ACK/NACK response (or ACK/NACK response group of another binding) of another binding by SR resource.

In the middle of two ACK/NACK response, first can perform and transmit relevant space with the DL of two code words (2 CW) and bundle.Such as, if one in two ACK/NACK response relevant with a code word (1 CW) and two in another is relevant with 2 CW, then only 2 CW execution spaces are bundled.Because only there is 1 CW in the SPSPDSCH in LTE version 8/9, so space binding cannot be performed to SPSPDSCH, and and if only if space can be performed when " PDSCH corresponding with the PDCCH with DAI=1 " or " DLSPS with DAI=1 discharges PDCCH " is configured to 2 CW and bundle.Then, relative to 2,3 or 4 bits before the binding of space, ACK/NACK payload is reduced to 2 bits.Like this, space binding can be performed as necessary, and therefore, 2 bit ACK/NACK response can be launched by PUCCH format 1b (or 1a).

At this moment, the resource of the PUCCH format 1 of distributing into SR transmission can be used for first PUCCH resource of PUCCH format 1b (1a).As necessary (when using SORTD), the second PUCCH resource for PUCCH format 1b (1a) can use the Secondary resource of the PUCCH format 1 into RS transmission distribution.Such PUCCH format and Resourse Distribute can indicate corresponding two ACK/NACK response return back to PUCCH format 1a and be re-used by phase rotating, that is, one in two ACK/NACK response is mapped to I channel and another is mapped to Q channel.Or such PUCCH format and Resourse Distribute can indicate two ACK/NACK responses to return back to PUCCH format 1b.

In other words, launch ACK/NACK information by using SR resource and can perform SR, and can be launched for the ACK/NACK of " SPSPDSCH " and the ACK/NACK for " PDSCH corresponding with PDCCH " or " DLSPS discharges PDCCH " by the constellation mapping in SR resource.

Such as, in the 2 bit ACK/NACK response used in the PUCCH format 1b of definition in LTE version 8, MSB can be mapped to ACK/NACK for " SPSPDSCH " and LSB can be mapped to for " PDSCH corresponding with the PDCCH with DAI=1 " or the ACK/NACK for having " DLSPS of DAI=1 discharges PDCCH ".Or, in the contrary mode of above-mentioned example, corresponding ACK/NACK response can be mapped to MSB and LSB.2 mapped bit ACK/nack message can be launched by SR resource.

As another example, in QPSK constellation, ACK/NACK for " SPSPDSCH " can be mapped to I axle, and " PDSCH corresponding with the PDCCH with DAI=1 " or Q axle can be mapped to for the ACK/NACK of " DLSPS with DAI=1 discharges PDCCH ".Or, in the contrary mode of above-mentioned example, corresponding ACK/NACK response can be mapped to I axle and Q axle.In addition, in the ACK/NACK for " SPSPDSCH " and the ACK/NACK for " PDSCH corresponding with the PDCCH with DAI=1 " or " SPS with DAI=1 discharges PDCCH ", I axle can be mapped to according to time sequencing for the ACK/NACK of the channel first received and ACK/NACK for the channel received afterwards can be mapped to Q axle.Or, in the contrary mode of above-mentioned example, corresponding ACK/NACK response can be mapped to I axle and Q axle.2 mapped bit ACK/nack message can be launched by SR resource.

As another example, in QPSK constellation, ' 1,1 ' and ' 0,0 ' can be mapped to the ACK/NACK for " SPSPDSCH ", and ' 0,1 ' and ' 1,0 ' can be mapped to " PDSCH corresponding with the PDCCH with DAI=1 " or " DLSPS with DAI=1 discharges PDCCH ".Or, in the mode contrary to above-mentioned example corresponding ACK/NACK can be responded and be mapped to I axle and Q axle.2 mapped bit ACK/nack message can be launched by SR resource.

Can apply the mapping as the ACK/NACK for the DL transmission in QPSK constellation in the examples described above in an identical manner, whether the transmission mode (TM) regardless of each community is whether MIMO or space binding are actually applied.

According to above-mentioned example, the binding of the ACK/NACK information of being launched by SR resource is minimized, and can be launched steadily the ACK/NACK response of SPSPDDSCH.

In the examples described above, although suppose transmitting two ACK/NACK responses for convenience of description, the transmission method of two ACK/NACK responses can be expanded and be applied to the transmission more than two ACK/NACK responses.That is, two virtual A CK/NACK response groups can be designated as more than the response of the ACK/NACK of two and can be launched by such as QPSK constellation mapping in the examples described above.Such as, ACK/NACK information for " SPSPDSCH " can be mapped to I axle and other ACK/NACK information (that is, for the ACK/NACK information of " PDSCH corresponding with PDCCH " and/or " DLSPS discharges PDCCH ") can be generated as 1 bit ACK/nack message by space binding and time domain binding and can be mapped to Q axle.2 mapped bit ACK/nack message can be launched by SR resource.According to this example, because the ACK/NACK information that the ACK/NACK information for SPSPDSCH of can distinguishing is transmitted with the DL for other, so the detection perform of the ACK/NACK for SPSPDSCH can be improved.

Embodiment 16-1

When needing to launch ACK/NACK and SR when UE receives one " SPSPDSCH " and one " PDSCH corresponding with the PDCCH with DAI=1 " or one " DLSPS discharges PDCCH " in TDD simultaneously, PUCCH format 1b can be used to launch ACK/NACK counter by SR resource.

The transmission of ACK/NACK counter refers to the information generating how many ACK in the ACK/NACK response all when not launching each ACK/NACK response (or ACK/NACK information of binding) and is fed.The number (ACK counter information) of ACK can be mapped to QPSK constellation and then be launched.

Such as, in QPSK constellation, " 00 " can indicate does not exist ACK, and " 01 " can indicate existence ACK, and " 10 " can indicate existence two ACK, and " 11 " can indicate existence three ACK.Then, relative to 2 to 4 bits, ACK/NACK transport payload is reduced to 2 bits.PUCCH format 1b (/ 1a) can be passed through and launch 2 bit ACK/nack message.

Under these circumstances, can use as SR transmission and the resource of PUCCH format 1 of distributing for first PUCCH resource of PUCCH format 1b (/ 1a).As necessary (when using SORTD), the second PUCCH resource for PUCCH format 1b (/ 1a) can use the Secondary resource into the PUCCH format 1 that RS transmits and distribute.Such PUCCH format and Resourse Distribute can indicate and represent that the corresponding bit of ACK/NACK counter is return back to PUCCH format 1a and is re-used by phase rotating, that is, one in the bit of ACK/NACK counter information is indicated to be mapped to I channel and another is mapped to Q channel.Or such PUCCH format and Resourse Distribute can indicate two bits to return back to PUCCH format 1b.That is, SR can be performed by using SR resource to launch ACK/NACK information, and ACK/NACK counter information can be launched by the constellation mapping in SR resource.

Although described the transmission of two ACK/NACK responses in the examples described above for convenience of description, principle of the present invention can be applied to the transmission responded more than the ACK/NACK of two.Such as, respond for the ACK/NACK more than two, ACK/NACK counter information can be repeatedly mapped to two bits.Such as, in QPSK constellation, " 00 " can indicate does not exist ACK, and " 01 " can indicate existence one or four ACK, and " 10 " can indicate existence 2 or 5 ACK, and " 11 " can indicate existence 3 or 6 ACK.

Embodiment 17

In traditional LTE version 8 system, PUCCH format 2/2a/2b is defined as launching CSI (CQI/PMI/RI).In order to launch ACK/NACK and CSI simultaneously, PUCCH format 2a/2b can be used.Particularly, can by modulated applications be launched ACK/NACK information in the RS symbol of PUCCH format 2a/2b.

Such as, as as shown in following table 19, by a modulation symbol (d (10)) can be generated about 1 bit (b (20)) or the modulation of 2-bit (b (20), b (21)) ACK/NACK information and executing.

[table 19]

The modulation symbol (d (10)) be generated can be re-used between the generation of the RS sequence of PUCCH, and then uses PUCCH format 2a/2b to be launched.For the details relevant with PUCCH format 2a/2b, can with reference to the chapters and sections 5.4.2 of 3GPPTS36.211.

In embodiment 17, describe the method for launching ACK/NACK and CSI (that is, in identical subframe) when two ACK/NACK responses should be launched simultaneously in detail.Assuming that by transmission (that is, the while of ACK/NACK and CSI, transformation parameter is set to TRUE) while higher level configuration ACK/NACK and CSI.The meaning of " ACK/NACK and CSI simultaneously transformation parameter is set to TRUE " is when ACK/NACK transmission launches ACK/NACK and CSI with during CSI transmission collision when not abandoning CSI simultaneously.

Two ACK/NACK responses can be to the response of " SPSPDSCH " and the response to " having the PDSCH of corresponding PDCCH ".Or two ACK/NACK responses can be to the response of " SPSPDSCH " and the response to " DLSPS discharges PDCCH ".In the middle of these channels, the PDCCH in " there is the PDSCH of corresponding PDCCH " or " DLSPS discharges PDCCH " can have be 1 DLDAI value.In the present invention, an ACK/NACK response can correspond to an ACK/NACK response group.That is, two ACK/NACK responses can refer to two ACK/NACK response groups.

The present invention proposes when needs launch two ACK/NACK responses and CSI simultaneously, use the transmission as ACK/NACK response (or an ACK/NACK response group) of the RS modulation symbol as shown in table 19 and the ACK/NACK response (or ACK/NACK response group of a binding) of a binding by PUCCH format 2a (/ 2b).

In the middle of two ACK/NACK responses, first can perform the space binding about the ACK/NACK response transmitted 2-CWDL.Such as, one in two ACK/NACK response is about 1 CW and another is about 2 CW, only can perform spaces binding about 2 CW.In LTE version 8/9, because only there is 1 CW in SPSPDSCH, so do not need perform space binding to SPSPDSCH and and if only if space can be performed when " PDSCH corresponding with the PDCCH with DAI=1 " or " DLPSS with DAI=1 discharges PDCCH " is made up of 2 CW and bundle.Then, relative to 2,3 or 4 bits before the binding of space, ACK/NACK payload is reduced to 2 bits.Therefore, PUCCH format 2b (/ 2a) can be passed through as necessary and launch 2 bit ACK/NACK response.

Such PUCCH format and Resourse Distribute can indicate and use multiplexing corresponding two ACK/NACK response of PUCCH format 2a by phase rotating, that is, one in two ACK/NACK responses is mapped to I channel and another is mapped to Q channel.Or such PUCCH format and Resourse Distribute can indicate two ACK/NACK responses to be multiplexed to PUCCH format 2b.

In other words, the constellation mapping can passed through in the RS modulation symbol in PUCCH format 2b (/ 2a) is launched for the ACK/NACK of " SPSPDSCH " and the ACK/NACK for " PDSCH corresponding with PDCCH " or " DLSPS discharges PDCCH ".

Such as, in 2 bits in RS modulation symbol d (10) in table 19, MSB can be mapped to the ACK/NACK for " SPSPDSCH ", and LSB can be mapped to for " PDSCH corresponding with the PDCCH with DAI=1 " or the ACK/NACK for " DLSPS with DAI=1 discharges PDCCH ".Or, in the contrary mode of above-mentioned example, corresponding ACK/NACK response can be mapped to MSB and LSB.Like this, 2 bit ACK/nack message can be mapped to RS modulation symbol and be launched by PUCCH format 2b (/ 2a).

As another example, in the QPSK constellation of the RS modulation symbol d (10) of table 19, the ACK/NACK for " SPSPDSCH " can be mapped to I axle and " PDSCH corresponding with the PDCCH with DAI=1 " or can be mapped to Q axle for the ACK/NACK of " DLSPS with DAI=1 discharges PDCCH ".Or, in the contrary mode of above-mentioned example, corresponding ACK/NACK response can be mapped to I axle and Q axle.In addition, in the ACK/NACK for " SPSPDSCH " and the ACK/NACK for " PDSCH corresponding with the PDCCH with DAI=1 " or " SPS with DAI=1 discharges PDCCH ", I axle can be mapped to according to time sequencing for the ACK/NACK of the channel first received and ACK/NACK for the channel received afterwards can be mapped to Q axle.Or, in the contrary mode of above-mentioned example, corresponding ACK/NACK response can be mapped to I axle and Q axle.Therefore, 2 bit ACK/nack message can be mapped to RS modulation symbol and be launched by PUCCH format 2b (/ 2a).

As another example, in QPSK constellation in the RS modulation symbol d (10) of table 19, ' 1,1 ' and ' 0,0 ' can be mapped to the ACK/NACK for " SPSPDSCH ", and the ACK/NACK that ' 0,1 ' and ' 1,0 ' can be mapped to " PDSCH corresponding with the PDCCH with DAI=1 " or " DLSPS with DAI=1 discharges PDCCH ".Or, with the scheme contrary to above-mentioned example corresponding ACK/NACK can be responded and be mapped to I axle and Q axle.Therefore, 2 bit ACK/nack message can be mapped to RS modulation symbol and be launched by PUCCH format 2b (/ 2a).

Whether the mapping as the ACK/NACK for the DL transmission in QPSK constellation in the examples described above can be applied in an identical manner, and be whether MIMO or space binding are actually applied regardless of the TM of each community.

According to above-mentioned example, the binding of the ACK/NACK information of being launched by CSI channel resource is minimized, and can be launched steadily the ACK/NACK response of SPSPDDSCH.

In the examples described above, although suppose transmitting two ACK/NACK responses for convenience of description, the transmission method of two ACK/NACK responses can be applied to the transmission more than two ACK/NACK responses.That is, the response more than the ACK/NACK of two can be designated as two virtual A CK/NACK response groups, and can be launched by such as QPSK constellation mapping in the examples described above.Such as, ACK/NACK information for " SPSPDSCH " can be mapped to I axle and other ACK/NACK information (that is, for the ACK/NACK information of " PDSCH corresponding with PDCCH " and/or " DLSPS discharges PDCCH ") can be generated as 1 bit ACK/nack message by space binding and time domain binding and can be mapped to Q axle.Therefore, 2 bit ACK/nack message can be mapped to RS modulation symbol and be launched by PUCCH format 2b (/ 2a).According to this example, because the ACK/NACK information can distinguished for SPSPDSCH and other ACK/NACK information transmitted for DL, so the detection perform of the ACK/NACK for SPSPDSCH can be improved.

Embodiment 17-1

When in TDD, UE receives one " SPSPDSCH " and one " PDSCH corresponding with the PDCCH with DAI=1 " or " DLSPS discharges PDCCH ", need to launch ACK/NACK and CSI simultaneously.Transmission while configuring ACK/NACK and CSI by higher level (ACK/NACK and CSI be transformation parameter=TRUE simultaneously), PUCCH format 2b (/ 2a) can be used as being used for launching the method for ACK/NACK and CSI (that is, in identical subframe) to launch ACK/NACK counter simultaneously.

The transmission of ACK/NACK counter refers to the information (or tied ACK/NACK information) generating how many ACK in the ACK/NACK response all when not launching each ACK/NACK and responding and is fed.The number (ACK counter information) of ACK can be mapped to the QPSK constellation as the RS modulation symbol d (10) shown in table 19 and then be launched.

Such as, in QPSK constellation, ' 00 ' can indicate and there is not ACK, and ' 01 ' can indicate existence ACK, and ' 10 ' can indicate existence two ACK, and ' 11 ' can indicate existence three ACK.Then, relative to 2 to 4 bits (2 or 3 bits), ACK/NACK transport payload is reduced to 2 bits.PUCCH format 2b (/ 2a) can be passed through and launch 2 bit ACK/nack message.

Although described the transmission of two ACK/NACK responses in the examples described above for convenience of description, principle of the present invention can be applied to the transmission responded more than the ACK/NACK of two.Such as, the ACK/NACK counter information for the ACK/NACK response more than two can be repeatedly mapped to two bits.Such as, on QPSK constellation ' 00 ' can indicate and there is not ACK, and ' 01 ' can indicate existence one or four ACK, and ' 10 ' can indicate existence 2 or 5 ACK, and ' 11 ' can indicate existence 3 or 6 ACK.

Embodiment 18

In embodiment 18, describe the method for launching ACK/NACK and another UCI (SR or CSI) transmitted for DL in FDD system.

First, assuming that CA configuration FDD system in PUCCH format 3 be substantially used to ACK/NACK feedback.Also suppose that the TPC field in the PDCCH of the PDSCH for launching on PCell or in the PDCCH discharged for DLSPS is used to original TPC command, and the TPC field in the one or more PDCCH launched on one or more SCell is used to ARI object.

If there is at least one PDSCH on one or more SCell, then PUCCH format 3 can be used to ACK/NACK feedback.

If there is not PDSCH transmission on SCell, then can use resource and the ACK/NACK mapping ruler of PUCCH format 1a/1b.Particularly, if there is not PDCCH and PDSCH when there is not the PDCCH corresponding with PDSCH on SCell on PCell, then because there is not DL transmission (that is, DTX), so PUCCH format 1a/1b is not launched.Simultaneously, if there is PDSCH (SPSPDSCH or the PDSCH corresponding with PDCCH) when there is not the PDCCH corresponding with PDSCH on SCell or there is the PDCCH indicating DLSPS to discharge on PCell on PCell, then can launch ACK/NACK by PUCCH format 1a/1b.

When supposing above-mentioned ACK/NACK transmission operation, when should launch ACK/NACK in the subframe wherein by higher level configuration SR transmission, following operation can be performed.

If there is at least one PDCCH corresponding with PDSCH on PCell with SCell, then SR and ACK/NACK information is jointly encoded or is re-used and is launched by PUCCH format 3.

If there is not PDCCH and PDSCH when there is not the PDCCH corresponding with PDSCH on SCell on PCell, then because there is not DL transmission (that is, DTX), so PUCCH format 1a/1b is not launched.Under these circumstances, positive/negative SR is launched by on-off keying (OOK) scheme.That is, the transmission about SR resource corresponds to negative SR corresponding to positive SR and about the non-transmitting of SR resource.

If there is PDSCH (SPSPDSCH or the PDSCH corresponding with PDCCH) when there is not the PDCCH corresponding with PDSCH on SCell or there is the PDCCH indicating DLSPS to discharge on PCell on PCell, then can launch SR and ACK/NACK information by using PUCCH format 1a/1b to launch ACK/NACK information in SR resource.Particularly, when positive SR, in SRPUCCH transmitted on resources ACK/NACK information, and when negative SR, can in ACK/NACKPUCCH transmitted on resources ACK/NACK information.

Next, transmit while will ACK/NACK and CSI being described.In the present embodiment, assuming that by transmission while higher level configuration ACK/NACK and CSI.

If there is not PDCCH and PDSCH when there is not the PDCCH corresponding with PDSCH on SCell on PCell, then because there is not DL transmission (that is, DTX), so PUCCH format 1a/1b is not launched.Under these circumstances, a series of PUCCH format 2 is used can to launch the CSI in cycle when not launching ACK/NACK information.

If there is PDSCH (SPSPDSCH or the PDSCH corresponding with PDCCH) when there is not the PDCCH corresponding with PDSCH on SCell and there is the PDCCH indicating DLSPS to discharge on PCell on PCell, then a series of PUCCH format 2 can be used multiplexing and launch ACK/NACK information and CSI.Particularly, ACK/NACK information can be launched by the RS modulation symbol of PUCCH format 2a/2b.In addition, when normal CP, PUCCH format 2a/2b can be used to launch CSI and ACK/NACK information, and when the CP expanded, PUCCH format 2 can be used to launch the CSI of combined coding.

Embodiment 19

In embodiment 19, describe in the TDD system for configuring at CA the method for ACK/NACK and another UCI (SR or CSI) launched for DL transmission.Particularly, the DAI field that the present embodiment relates to PDCCH is used as the situation of ARI.

First, assuming that CA configuration FDD system in PUCCH format 3 be substantially used to ACK/NACK feedback.Also suppose that the TPC field in the PDCCH of the PDSCH for launching on PCell is used to original TPC command, and the DAI field in the PDCCH of the PDSCH for launching on PCell is used to ARI object.In addition, assuming that the TPC field (or DAI field) for the one or more PDCCH of PDSCH launched on one or more SCell is used as ARI.

In further detail, on PCell in the PDCCH of the PDCCH or instruction SPS release that dispatch PDSCH, the TPC field in PDCCH can be used to TPC command and the DAI field of PDCCH can be used as PUCCH format 3 ARI.TPC field for dispatching the PDCCH of the PDSCH on SCell can be used as the ARI for PUCCH format 3.At this, assuming that the ARI value of all PDCCH on PCell with SCell is identical.

If there is at least one PDSCH or there is at least one PDSCH on SCell on PCell, then PUCCH format 3 can be used to ACK/NACK feedback.

If there is not the PDSCH corresponding with PDCCH on PCell with SCell, then can use resource and the ACK/NACK mapping ruler of the PUCCH format 1a/1b of LTE version 8.Particularly, if there is not SPSPDSCH when there is not the PDCCH corresponding with PDSCH on PCell with SCell, then the transmission corresponding to DTX and PUCCH format 1a/1b is not launched.

Meanwhile, if there is SPSPDSCH when there is not the PDSCH corresponding with PDCCH on PCell with SCell on PCell, then can launch ACK/NACK by PUCCH format 1a/1b.

The transmission of ACK/NACK and SR can be performed as follows.

If there is at least one PDCCH corresponding with PDSCH on PCell with SCell, then SR and ACK/NACK information can be jointly encoded or be re-used and is launched by PUCCH format 3.

If there is not the PDSCH corresponding with PDCCH and also there is not SPSPDSCH on PCell with SCell, then the transmission corresponding to DTX and PUCCH format 1a/1b is not launched.Under these circumstances, SR transmission can be performed by OOK scheme.

If there is not the PDSCH corresponding with PDCCH and there is SPSPDSCH on PCell with SCell on PCell, then can launch SR and ACK/NACK information by using PUCCH format 1a/1b to launch ACK/NACK information in SR resource.

The transmission of ACK/NACK and CSI can be configured as follows.

If there is not the PDCCH corresponding with PDSCH and there is not SPSPDSCH on PCell with SCell, then the transmission corresponding to DTX and PUCCH format 1a/1b is not launched.Under these circumstances, a series of PUCCH format 2 can be used to launch the CSI in cycle.

If there is not the PDSCH corresponding with PDCCH and launch SPSPDSCH on PCell with SCell on PCell, then ACK/NACK information and CSI are re-used and launch.Particularly, when normal CP, PUCCH format 2a/2b can be used to launch CSI and ACK/NACK information, and when the CP expanded, PUCCH format 2 can be used to launch CSI and ACK/NACK be jointly encoded.

Embodiment 20

In embodiment 20, describe and be used for the ACK/NACK of transmitting for DL transmission and the method for another UCI (SR or CSI) in the TDD system of CA configuration.Particularly, the TPC field that the present embodiment relates to wherein PDCCH is used as the situation of ARI.

In the present embodiment, assuming that the DAI field of PDCCH and TPC field are defined as foloows.

DAI field on PCell is used as the counter of the PDCCH on PCell.DAI field on SCell can be used as one in following proposal.First scheme is the PDCCH counter that the DAI field on SCell is used as on corresponding SCell.Another program is that the DAI field on SCell is set to ' 00 ' and makes even in public search space, to dispatch DCI.With regard to UE implements, predetermined value ' 00 ' also can be used as virtual CRC.

Meanwhile, the TPC field (that is, having the PDCCH of DAI=' 00 ' or DAI=1) of first PCell distributing is used to original TPC object.The TPC field of other all PDCCH (all PDCCH had on PDCCH and SCell of DAI>1 on PCell) is used to ARI object.Assuming that be identical in the ARI value transmitted on corresponding all PDCCH with a PUCCH.

If there is PDSCH transmission and there is not the PDCCH corresponding with PDSCH transmission on PCell, then UE operates as follows.If there is no PDSCH transmission, then UE can use PUCCH format 1a/1b to launch ACK/NACK.Meanwhile, if there is PDSCH transmission, then UE can use PUCCH format 3 to launch ACK/NACK (exception, the TPC field with the PDCCH of DAI=' 00 ' can be used as ARI).

In other cases, if existed with PDCCH (having the PDCCH of DAI=' 00 ' (or DAI=1)) on PCell if a corresponding PDSCH or there is the PDCCH (having the PDCCH of DAI=' 00 ' (or DAI=1)) indicating DLSPS to discharge on PCell, then UE can use PUCCH format 1a/1b transmitting ACK/NACK.In other words, PUCCH format 3 can be used to launch ACK/NACK.

In a word, when there is the PDSCH (SPSPDSCH) that does not have corresponding PDCCH on PCell, only on PCell, there is the PDSCH that has corresponding PDCCH (having the PDCCH of DAI=' 00 ' (or DAI=1)), or when only there is a PDCCH (there is the PDCCH of DAI=' 00 ' (or DAI=1)) of instruction DLSPS release when there is not PDSCH on SCell on PCell, can PUCCH format 1a/1b be used.In other cases, PUCCH format 3 can be used.At this, when there is not the PDSCH without corresponding PDCCH on PCell, the TPC field with the PDCCH (PDCCH of the PDCCH corresponding with PDSCH or instruction DLSPS release) of DAI=' 00 ' (or DAI=1) is used to TPC field instructs and other the TPC field of PDCCH is used to ARI object.In other cases, the TPC field of all PDCCH is used to ARI object.The UE value being used as the field of ARI that supposition is being transmitted in corresponding all PDCCH with a PUCCH is identical.

If wherein by needing to launch positive SR and ACK/NACK in the subframe of higher level configuration SR transmission under the state performing ACK/NACK as above transmission, then following operation can be performed.

When there is a PDSCH without corresponding PDCCH on PCell, only on PCell, there is a PDSCH corresponding with the PDCCH with DAI=1 (or DAI=' 00 '), or on PCell, only there is a PDCCH with DAI=1 (or DAI=' 00 ') and instruction DLSPS release, and SR and ACK/NACK information can be launched by using PUCCH format 1a/1b to launch ACK/NACK information in SR resource.

Such as, if be configured to equally with in above-mentioned only PCell reception condition launch ACK/NACK information and SR in a tdd system in identical frame, then UE can use PUCCH format 1b to launch ACK/NACK counter by SR resource.ACK/NACK counter is the information of the number of the ACK indicated in the middle of multiple ACK/NACK response.Such as, if ACK/NACK counter is expressed as 2 bits (b (0), b (1)), then ' 00 ' represents to there is not ACK, and ' 01 ' represents existence ACK, ' 10 ' represents existence two ACK, and ' 11 ' represents existence three ACK.Or, if ACK counter information is repeatedly mapped to 2 bits (b (0) by license, b (1)), then ' 00 ' can indicate and there is not ACK, ' 01 ' can indicate existence one or four ACK, ' 10 ' can indicate existence 2 or 4 ACK, and ' 11 ' can indicate existence 3 or 6 ACK.On the other hand, transmit for negative SR, UE launches ACK/NACK response (such as, the ACK/NACK response of binding) by ACK/NACKPUCCH resource.

Other situation (namely, except there is a PDSCH without corresponding PDCCH on PCell, the PDSCH that only existence one is corresponding with the PDCCH with DAI=1 (or DAI=' 00 ') on PCell, or only exist on PCell and there is DAI=1 (or DAI=' 00 ') and situation outside the situation of the PDCCH indicating DLSPS to discharge), SR and ACK/NACK is jointly encoded with multiplexing and use PUCCH format 3 to launch.

If there is a PDSCH without corresponding PDCCH on PCell, only on PCell, there is a PDSCH corresponding with the PDCCH with DAI=1 (or DAI=' 00 '), or only exist on PCell and there is DAI=1 (or DAI=' 00 ') and the PDCCH indicating DLSPS discharge, then can use the multiplexing and transmitting ACK/NACK information and CSI of a series of PUCCH format 2.Particularly, ACK/NACK information can be launched by the RS modulation symbol of PUCCH format 2/2a/2b.In addition, when normal CP, PUCCH format 2a/2b can be used to launch CSI and ACK/NACK information, and when the CP expanded, PUCCH format 2 can be used to launch CSI and ACK/NACK of combined coding.

Such as, if be configured to equally with in above-mentioned only PCell reception condition launch ACK/NACK information and CSI (CQI/PMI/RI) in a tdd system and transmit while using a series of PUCCH format 2 to perform ACK/NACK information and CSI in identical frame, then can launch ACK/NACK counter information by the RS modulation symbol of PUCCH format 2/2a/2b.Such as, if ACK/NACK counter is expressed as 2 bits (b (0), b (1)), then ' 00 ' represents to there is not ACK, ' 01 ' represents existence one or four ACK, ' 10 ' represents existence two ACK, and ' 11 ' represents existence three ACK.Or, if ACK counter information is repeatedly mapped to 2 bits (b (0) by license, b (1)), then ' 00 ' can indicate and there is not ACK, ' 01 ' can indicate existence 1 or 4 ACK, ' 10 ' can indicate existence 2 or 5 ACK, and ' 11 ' can indicate existence 3 or 6 ACK.When normal CP, PUCCH format 2b and CSI can be used to launch ACK/NACK counter information together, and when the CP expanded, PUCCH format 2 can be used together with CSI to launch ACK/NACK counter information.
