Fig. 2 be shown in UE and BS each in the example arrangement of emitter.Retouch in more detail below with reference to Fig. 2 State the operation of emitter 100a and 100b.

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

Emitter 100a and 100b can launch more than a code word.Scrambler 301 scrambles the encoding ratio of each code word Spy, for launching on the physical channel.Code word can be referred to as data stream, and is equal to the data block provided from MAC layer.From The data block that MAC layer provides is referred to as transmission block.

The bit modulation of scrambling is complex-value modulation symbol by modulation mapper 302.Modulation mapper 302 can be according in advance Scrambler bits is modulated to represent the complex-value modulation symbol of the position on signal constellation (in digital modulation) by modulation scheme.Modulation scheme not by Limit, and m phase-shift keying (PSK) (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 be with precoding complex modulation symbols on each layer, to be launched by antenna port.More Specifically, precoder 304 is by processing for multiple transmitting antenna 500-1 to 500-N with MIMO scheme_tComplex-value modulation Symbol produces antenna special symbol, and distributes this antenna special symbol to RE mapper 305.That is, precoder 304 will be sent out Penetrate layer and be mapped to antenna port.The output x of layer mapper 303 can be multiplied by N by precoder 304_t×M_tPre-coding matrix W, and And with N_t×M_FThe form of matrix z exports the product that result produces.

The complex-value modulation symbol being used for corresponding antenna port is mapped/is assigned to RE by RE mapper 305.RE mapper The 305 complex-value modulation symbols that can be used for corresponding antenna port to suitable subcarrier distribution, and can come according to UE Multiplexing they.

Ofdm signal generator 306 is modulated for corresponding antenna by OFDM or single carrier frequency division multiplexing (SC-FDM) The complex-value modulation symbol of port, i.e. antenna special symbol, thus produces complex values time domain OFDM or SC-FDM mark signal. Ofdm signal generator 306 can perform inverse fast fourier transform (IFFT) for antenna special symbol, and produces to result Raw IFFT time-domain symbol is inserted into Cyclic Prefix (CP).OFDM symbol is rear by launching at digital-to-analogue conversion, frequency upooaversion etc. Antenna 500-1 to 500-N_tIt is launched into receptor.Ofdm signal generator 306 can include IFFT module, CP inserter, number Weighted-voltage D/A converter (DAC), Frequency up-converter etc..

Meanwhile, if emitter 100a and 100b uses SC-FDMA for the transmitting of code word, then emitter 100a and 100b Discrete Fourier (DFT) module 307 (or fast fourier transform (FFT) module) can be included.DFT block is specific for antenna Semiology analysis DFT or FFT, and export DFT/FFT symbol to RE mapper 305.SC-FDMA is for by reducing signal Peak-to-average power ratio (PAPR) or cubic metric (CM) and launch the launch scenario of signal.According to SC-FDMA, can be with obstructed overpower Amplifier nonlinearity distortion zone and launch signal.Therefore, even if when emitter is with than the power in conventional OFDM scheme During low power transmission signal, receptor also is able to receive the signal meeting constant intensity or error rate.I.e., it is possible to pass through SC- FDMA reduces the power consumption of emitter.

In conventional ofdm signal generator, on each carrier wave the signal of carrying while by IFFT by overloading Ripple modulation (MCM) is launched the most simultaneously, thus reduces the efficiency of power amplifier.On the other hand, in SC-FDMA, Information carried out DFT/FFT before signal is mapped to subcarrier.By the signal of DFT block 307 by DFT/FFT effect Increase PAPR.The signal that DFT/FFT processes is mapped to subcarrier, by IFFT process, and is converted into time-domain signal. That is, SC-FDMA emitter is in execution DFT or the FFT operation that takes a step forward of ofdm signal generator so that launch the PAPR of signal It is increased in IFFT input stage, and is finally reduced while again by IFFT.The program is referred to as DFT extension OFDM (DFT-s-OFDM), because seeming to seem to add before existing ofdm signal generator DFT block (or FFT Module) 307.

SC-FDMA is it suffices that single carrier property.Fig. 3 is shown in and meets while single carrier property in a frequency domain to sub-load Ripple maps the example of incoming symbol.If DFT symbol being assigned to son according to one of scheme shown in Fig. 3 (a) and 3 (b) Carrier wave, then can obtain the transmitting signal meeting single carrier property.Fig. 3 (a) illustrates centralized mapping, and Fig. 3 (b) diagram point Cloth maps.

Meanwhile, emitter 100a and 100b can use sub-clustering DFT extension OFDM (DFT-s-OFDM).Sub-clustering DFT-s- OFDM is the revision of conventional SC-FDMA.In sub-clustering DFT-s-OFDM, by DFT/FFT module 307 and precoder The signal of 304 is divided into the sub-block of predetermined quantity, and is mapped to subcarrier in a discontinuous manner.Fig. 4 to 6 diagram is passed through Incoming symbol is mapped to the example of single carrier by sub-clustering DFT-s-OFDM.

Fig. 4 diagram is mapped to the signal processing behaviour of single carrier for the output sampling processed by DFT in sub-clustering SC-FDMA Make.Fig. 5 and 6 is shown in sub-clustering SC-FDMA the output sampling processed by DFT and is mapped to the signal processing operations of multicarrier.Fig. 4 The application of sub-clustering SC-FDMA in diagram carrier wave, and the application of Fig. 5 and 6 diagram intercarrier sub-clustering SC-FDMA.Fig. 5 is shown in following In the case of produced by the signal of single IFFT block: be aligned in continuously point when distributing component carrier the most continuously Subcarrier spacing between quantum carrier wave.Fig. 6 diagram is passed through multiple when distributing component carrier the most discontinuously The signal of IFFT block produces.

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

Because the quantity of DFT block equal to IFFT block quantity and therefore DFT block and IFFT block the most corresponding, so Segmentation SC-FDMA is DFT extension and the simple expansion of IFFT subcarrier mapping structure of conventional SC-FDMA, and can be by table Reach for NxSC-FDMA or NxDFT-s-OFDMA.In the disclosure, segmentation SC-FDMA includes all these project.See figure 7, in segmentation SC-FDMA, all modulation symbols in the time domain are divided into N group (wherein, N is greater than the integer of 1), and DFT process is carried out, in order to release single carrier property constraint in units of group.

Run with the backward with the operation of emitter 100a and 100b referring back to Fig. 2, receptor 300a and 300b.Connect Receive device 300a and 300b decoding and demodulation by antenna 500a and 500b from the radio signal of external reception, and to processor 400a and 400b transmits the signal of demodulation.Antenna 500a and 500b of each being connected to receptor 300a and 300b can wrap Include N_rIndividual reception antenna.The signal received by each reception antenna is recovered as baseband signal, and then passes through multiplexing It is recovered as the original data stream that emitter 100a and 100b launches with MIMO demodulation.Each of receptor 300a and 300b can To include: signal restorer, for reception signal is reverted to baseband signal；Multiplexer, for multiplexing reception and the letter of process Number；And, channel demodulator, for being demodulated into code word by the signal stream of multiplexing.Signal restorer, multiplexer and channel demodulator Can be configurable for performing the integration module of their function or independent module.More specifically, signal restorer is permissible Including: analog-digital converter (ADC), it is used for converting analog signals into digital signal；CP remover, for from digital signal Except CP；FFT module, for by for eliminate CP signal perform FFT produce frequency domain symbol；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 believes Road demodulator recovers the code word launched by emitter from emission layer.

Meanwhile, if receptor 300a and 300b receives the signal launched by SC-FDMA described with reference to Fig. 3 to 7, Then each of receptor 300a and 300b farther includes IFFT module.At IDFT/IFFT module I DFT/IFFT, reason RE solves The antenna special symbol that mapper recovers, and export IDT/IFFT symbol to multiplexer.

Although having described each of emitter 100a and 100b in Fig. 1 is to 7 to include that scrambler 301, modulation are reflected Emitter 302, layer mapper 303, precoder 304, RE mapper 305 and ofdm signal generator 306, but can be further Consider to produce scrambler 301, modulation mapper 302, layer mapper 303, precoder 304, RE mapper 305 and ofdm signal Raw device 306 covers in each of processor 400a and 400b of emitter 100a and 100b.Equally, although at Fig. 1 Each describing receptor 300a and 300b in 7 includes signal restorer, multiplexer and channel demodulator, but permissible Consider further to cover signal restorer, multiplexer and channel demodulator the processor 400a of receptor 300a and 300b and In each of 400b.For convenience of description, under following premise, description below is provided: scrambler 301, modulation mapper 302, layer mapper 303, precoder 304, RE mapper 305 and the ofdm signal generator 306 (feelings in SC-FDMA scheme Under condition, farther include DFT block 307) it is included in what processor 400a and 400b being configured to and control its operation separated In emitter 100a and 100b, and, signal restorer, multiplexer and channel demodulator are included in and are configured to and control its behaviour In receptor 300a and 300b that processor 400a with 400b made separates.But, even if scrambler 301, modulation mapper 302, layer mapper 303, precoder 304, RE mapper 305 and ofdm signal generator 306 (with 307) are included in process In device 400a and 400b, and signal restorer, multiplexer and channel demodulator are (in the case of SC-FDMA scheme, further Including IFFT module) it is included in processor 400a and 400b, it is also possible to apply embodiments of the invention in an identical manner.

Differently configured radio frame can be carried out according to dual-mode.Such as, in fdd mode, because being come by frequency Distinguish downlink transmission and up-link is launched, so radio frame includes downlink subframe or uplink sub-frames.

On the other hand, in tdd mode, because distinguishing downlink transmission and up-link transmitting, institute by the time Be divided into downlink subframe and uplink sub-frames with the subframe in frame, table 1 be shown in tdd mode exemplary on Line link-downlink configuration.

[table 1]

In Table 1, D represents that downlink subframe, U represent uplink sub-frames, and S represents special subframe.Special son Frame includes down link pilot timeslot (DwPTS), protective time slot (GP), three fields of uplink pilot time slot (UpPTS). DwPTS is the time slot being preserved for downlink transmission, and UpPTS is to be preserved for the time slot that up-link is launched.

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

Seeing Fig. 9, time slot includes multiple OFDM (OFDM) symbol in the time domain, and includes many in a frequency domain Individual Resource Block (RB).OFDM symbol can represent a symbol duration.RB includes multiple subcarriers in a frequency domain.OFDM Symbol can be referred to as OFDM symbol, SC-FDM symbol etc. according to Multiple Access scheme.The quantity of the OFDM symbol of each time slot can To depend on that channel width and Cyclic Prefix (CP) length change.Such as, in the case of normal CP, a time slot includes 7 OFDM symbol, and a time slot includes 6 OFDM symbol in the case of extension CP.Although for illustrative purpose at Fig. 8 The middle time slot being shown as subframe there are 7 OFDM symbol, but embodiments of the invention are also applied for having any other The subframe of the OFDM symbol of quantity.The resource being multiplied by a subcarrier including an OFDM symbol be referred to as resource element (RE) or Single-tone (tone).

See Fig. 9, can be by including N^DL/UL _RBN^RB _scIndividual subcarrier and N^DL/UL _symbThe money of individual OFDM or SC-FDM symbol Source grid is described in each time slot the signal launched.N^DL _RBThe quantity of expression RB in DL time slot, and N^UL _RBRepresent The quantity of the RB in UL time slot.N^DL _RBAnd N^UL _RBIt is respectively depending on DL transmitted bandwidth and UL transmitted bandwidth.Each OFDM symbol Include N in a frequency domain^DL/UL _RBN^RB _scIndividual subcarrier.The quantity of subcarrier in a carrier wave is determined according to FFT value.Son The type of carrier wave can be divided into the data subcarrier for data transmitting, for the RS subcarrier of RS transmitting with for protecting Band and the null subcarrier of DC component.Null subcarrier for DC component keeps being not used also during producing ofdm signal And it is mapped to carrier frequency f₀.This carrier frequency is also referred to as mid frequency.N^DL _symbRepresent OFDM in DL time slot or The quantity of SC-FDMA symbol, N^UL _symbThe quantity of the expression OFDM or SC-FDMA symbol in UL time slot, and N^RB _scRepresent structure Become the quantity of the subcarrier of a 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 is multiplied by N in a frequency domain^RB _scIndividual continuous subcarrier.Therefore, a PRB includes N^DL/UL _symb×N^RB _scIndividual RE.

Each RE in resource grid can be by the index in time slot to (k l) uniquely identifies.K be scope from 0 to N^DL/UL _RB×N^RB _scThe frequency domain of-1 indexes, 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.

Seeing Figure 10, each subframe can be divided into control area and data area.Control area includes from first One or more OFDM symbol that OFDM symbol starts.The control zone can being independently disposed in subframe in each subframe The quantity of the OFDM symbol used in territory.Launched about OFDM symbol by Physical Control Format Indicator Channel (PCFICH) The information of quantity.BS can launch various control information by control area to one or more UE.Launch for controlling information, Arq can be mixed to control area distribution physical downlink control channel (PDCCH), PCFICH and physics to refer to Show channel (PHICH).

BS launches to each UE or UE group and as transmitting the paging channel (PCH) of channel and descending chain on PDCCH Road share channel (DL-SCH) resource distribute be associated information, UL scheduling grant, mixing arq (HARQ) letter Breath, downlink allocation index (DAI) etc..

BS can launch the data for UE or UE group by data area.The data launched by data area also by It is referred to as user data.For the transmitting of user data, physical down link sharing channel can be distributed to data area (PDSCH).PCH and DL-SCH is launched by PDSCH.UE can be read by the control information that decoding is launched via PDCCH Take the data launched by PDSCH.Launched for indicating which UE or UE group is PDSCH data be launched into by PDCCH Information and for indicating how UE or UE group should receive the decode the information of PDSCH data.For example it is assumed that use radio Network Temporary Identifier (RNTI) ' A ' carrys out CRC and shelters specific PDCCH, and is launched about using radio by specific sub-frame Resource ' B ' (such as, frequency location) and use transport format information ' C ' (such as, transmitting block size, modulation scheme, coding information Deng) information of data launched.Then, UE in the cell uses its RNTI information to monitor PDCCH.Have RNTI ' A's ' UE receives PDCCH, and the information of the PDCCH by receiving receives the PDSCH indicated by ' B ' and ' C '.

Multiple PDCCH can be launched in control area.UE can monitor multiple PDCCH to detect its PDCCH.By The down link control information (DCI) of PDCCH carrying can according to DCI format in size and purpose different, and according to volume Code check is the most different.

DCI format can be applied independently for each UE, and can in a subframe the multiple UE of multiplexing PDCCH.The PDCCH of each UE can be by chnnel coding independently, enabling to PDCCH plus cyclic redundancy check (CRC) (CRC).Use the unique identifier of each UE to shelter CRC so that each UE is able to receive that its PDCCH.But, because of Substantially do not know the position that its PDCCH is launched into for UE, it requires that UE is for the corresponding DCI in each subframe All PDCCH of form perform blind Detecting (also referred to as blind decoding), until receiving the PDCCH with its identifier.

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

See Figure 11, UL subframe and can be divided into control area and data area in a frequency domain.Can be to control area Distribute one or more physical uplink control channel (PUCCH) to carry uplink control information (UCI).Can be to number One or more physical uplink link shared channels (PUSCH) are distributed to carry user data according to region.If UE uses SC- FDMA scheme is launched for up-link, then can not launch PUCCH and PUSCH simultaneously, in order to keep single carrier property.

The UCI carried by PUCCH can be different in size and purpose according to PUCCH format, and according to encoding rate And it is different in size.For example, it is possible to PUCCH format is 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, it is positioned at UL to send out The subcarrier at the two ends penetrating bandwidth is assigned to UL and controls information transmitting.DC subcarrier is retained and not be used in signal and launches In, and it is mapped to carrier frequency f in the frequency upooaversion caused by OFDM/SC-FDMA signal generator 306 processes₀。

To the RB in subframe, distribution is used for the PUCCH of UE.The RB of RB couple takies different son loads in two time slots Ripple.This frequency hopping being referred to as exceeding RB pair that boundary of time slot distributes to PUCCH.But, if not using frequency hopping, then RB is to taking Identical subcarrier.Unrelated with frequency hopping, in a subframe, it is assigned to one RB pair for the PUCCH of a UE, and because of This, in a UL subframe, identical PUCCH launches once by a RB in each time slot, twice altogether.

Hereinafter, for a subframe each PUCCH launch RB to being referred to as PUCCH region or PUCCH resource.Separately Outward, for convenience of description, the PUCCH of carrying acknowledgement/non-acknowledgement (ACK/NACK) is referred to as ACK/NACK PUCCH.Hold The PUCCH carrying CQI (CQI)/precoding matrix indicators (PMI)/order information (RI) is referred to as channel status letter Cease (CSI) PUCCH, and the PUCCH carrying dispatch request (SR) is referred to as SR PUCCH.

The PUCCH resource launched for UCI from BS is carried out to UE assignment according to explicitly or implicitly scheme.

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 launches number to UE/BS According to, then UE/BS decodes received data.If the data of being successfully decoded, then launch ACK to BS/UE.If data decoding is lost Lose, then launch NACK to BS/UE.In 3GPP LTE system, UE receives data cell (such as, PDSCH) from BS, and passes through By carrying for this data cell schedule information PDCCH resource determined by implicit expression PUCCH resource come to BS launch for The ACK/NACK of this data cell.

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

In LTE system, it is used for the PUCCH resource of ACK/NACK the most in advance to each UE distribution, and is positioned at community In multiple UE each time point by division in the way of use multiple PUCCH resource.Specifically, based on carrying PDSCH The PDCCH of schedule information implicitly determine the PUCCH resource launched for the ACK/NACK of UE, this PDSCH carries correspondence DL data.The whole region wherein launching PDCCH in DL subframe includes multiple control channel element (CCE), and, to UE The PDCCH launched includes one or more CCE.Each CCE includes multiple resource element group (REG) (such as, 9 REG).When When getting rid of reference signal (RS), a REG is made up of four continuous RE.UE launches ACK/ by the PUCCH resource of implicit expression NACK, the PUCCH resource of this implicit expression is used in constituting specific CCE index in the middle of the index of the CCE of the PDCCH received by UE The function of (such as, the first or minimum CCE index) is exported or calculates.

Seeing Figure 12, each PUCCH resource indexes corresponding to the PUCCH resource for ACK/NACK.Such as institute in Figure 12 Show, it is assumed that to launch PDSCH schedule information to UE by the PDCCH being made up of the CCE of numbering 4 to 6, then UE is by from CCE The minimum CCE of numbering 4, i.e. PDCCH, the PUCCH deriving or calculating, such as, by PUCCH numbering 4, to launch ACK/ to BS NACK.Figure 12 illustrates an example, wherein, exists until M' CCE in DL subframe, and in the UL sub-frame existence until M Individual PUCCH resource.Although M' can be equal to M, but M' can be different from M, and can come in an overlapping manner mapping CCE and PUCCH resource.

For example, it is possible to PUCCH resource index is defined below.

[equation 1]

$n_{PUCCH}^{\left(1\right)}=n_{CCE}+N_{PUCCH}^{\left(1\right)}$

Here, n⁽¹⁾ _PUCCHIt is the PUCCH resource index launched for ACK/NACK, N⁽¹⁾ _PUCCHReceive from higher level Signalling value, and n_CCERepresent the minimum CCE index launched for PDCCH.

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

Seeing Figure 13, the UL that general FDD wireless communication system is carried by a DL and carries corresponding to this DL brings Launch and receive data.BS and UE launches and receives data and/or the information of control of scheduling in units of subframe.By at UL/ In DL subframe, data are launched and received in the data area of configuration, and is come by the control area of configuration in UL/DL subframe Launch and receive control information.To this end, UL/DL subframe carries signal on various physical channels.Although for convenience based on FDD Scheme provides the explanation of Figure 13, but description above can also be applied to by the time domain by the radio frame of Fig. 8 It is divided into the TDD scheme of 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 Rate block is to use broader frequency band to use broader UL/DL bandwidth.Multicarrier system or carrier aggregation (CA) system refer to It is to be polymerized the system that each multiple carrier wave with the bandwidth more narrower than target bandwidth is supported for broadband.When polymerization has During multiple carrier wave of the bandwidth more narrower than target bandwidth, the bandwidth of polymerization carrier wave can be limited to the band used in conventional systems Wide, in order to keep the backward compatibility with legacy system.Such as, LTE system can support the band of 1.4,3,5,10,15 and 20MHz Width, and the bandwidth supported LTE system can be used to support ratio from senior LTE (LTE-A) system of LTE system improvement The broader bandwidth of 20MHz.Furthermore it is possible to define new bandwidth to support CA, and unrelated 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 join Examining, when the only one component carrier (CC) communication in the TDD, this is corresponding in the single carrier case (non-CA) of Figure 13 Communication.UL CC and DL CC is also known respectively as UL resource and DL resource.

For example, with reference to Figure 14, each of which 5 CC being 20MHz can be polymerized in each of UL and DL to support The bandwidth of 100MHz.Corresponding CC can be continuous or discontinuous in a frequency domain.For convenience, Figure 14 illustrates wherein UL The bandwidth of CC is identical with the bandwidth of DL CC and the situation of both symmetry.However, it is possible to determine the band of each CC independently Wide.For example, it is possible to 5MHz (UL CC0)+20MHz (UL CC1)+20MHz (UL CC2)+20MHz (UL CC3)+5MHz (UL CC4) mode configures the bandwidth of UL CC.It also is able to configure asymmetric CA, wherein, the quantity of UL CC and the quantity of DL CC Different.Asymmetric CA can be generated due to the restriction of available band, or can have a mind to be formed by network configuration.Example As, even if when BS manages X DL CC, it is possible to the frequency band received by particular UE can be restricted to Y (≤X) individual DL CC.? In the case of Gai, UE needs DL signal/data that monitoring is launched by Y CC.Even if it addition, when BS manage L UL CC time, energy Enough frequency bands received by particular UE can be limited to M (≤L) individual UL CC.Confined DL CC or UL CC quilt for particular UE It is referred to as the service UL or DL CC of configuration in particular UE.BS can be by activating some or all of the CC that managed by BS or logical Cross the next CC to UE distribution provisions quantity of some CC that disabling is managed by BS.BS can change the CC of activation/disabling, and changes The quantity of the CC activating/disabling.Meanwhile, BS can specifically or UE specifically configures the Z that first UE should monitor/receive with community Individual DL CC (wherein, 1≤Z≤Y≤X) is as main DL CC.And, BS can with community specifically or UE specifically configure UE should First N number of UL CC (wherein, 1≤N≤M≤L) of monitoring/reception is as main UL CC.By this way, for the limit of particular UE Main DL or the UL CC of system is also referred to as the service UL or DL CC of configuration in particular UE.Can specific with community, UE group is specific Ground or UE are specifically configured to the various parameters of CA.

Once BS community is specifically or UE is specifically to the available CC of UE distribution, does not the most disable at least the one of distributed CC Individual, unless reconfigure to UE overall CC distribute or UE be switched.Hereinafter, unless reconfigured and distributed no to the overall CC of UE The CC not disabled is referred to as main CC (PCC), and the CC that BS is free to activate/disable is referred to as assisting CC (SCC).Single Carrier communication uses the communication that a PCC is used between UE and BS, and does not use SCC for communicating.It is also possible to PCC and SCC is distinguished based on control information.For example, it is possible to be set to only launch by specific CC/connect by specific control information Receive.Such specific CC can be referred to as PCC, and other one or more CC can be referred to as one or more SCC.Example As, the control information launched by PUCCH can correspond to such specific control information.Therefore, if sent out on PUCCH The control information penetrated only can be transmitted into BS by PCC from UE, and the UL CC of the PUCCH that wherein there is UE can be referred to as UL PCC, and other one or more UL CC can be referred to as one or more UL SCC.As another example, if Use the specific CC of UE, then this particular UE can receive the DL synchronizing signal (SS) as specific control information from BS.In these feelings Under condition, this particular UE makes (that is, to be used for attempting access to for the DL CC setting up the synchronization of initial DL time by receiving DL SS The DL CC of the network of BS) DL PCC can be referred to as, and other one or more DL CC can be referred to as one or more DL SCC.In the communication system according to LTE-A version 10, multi-carrier communication uses a PCC and not for each UE Use SCC or use one or more SCC.But, this is the definition according to LTE-A, and can allow each in future UE uses the communication of multiple PCC.PCC can be referred to as main CC, grappling CC or main carrier, and SCC can be referred to as assisting CC Or subcarrier.

LTE-A uses the concept of community to manage radio resource.Community is defined as DL resource and the combination of UL resource, That is, DL CC and the combination of UL CC.Here, UL resource is not indispensable component.But, this is in current LTE-A standard In be defined, and in future, can allow to be used alone UL resource to configure community.Therefore, it can be used alone DL resource Or use DL resource and UL resource to configure community.When supporting CA, can be indicated in DL resource by system information Association between the carrier frequency of the carrier frequency of (or DL CC) and UL resource (or UL CC).For example, it is possible to believed by system Breath block type 2 (SIB2) indicates DL resource and the combination of UL resource.Here, carrier frequency indicates in each community or CC Frequency of heart.Can be referred to as main plot (PCell) in the upper community run of basic frequency (or PCC), and quenching frequency (or SCC) the upper one or more communities run can be referred to as one or more assisted cell (one or more SCell).Dominant frequency Rate (or PCC) refers to re-establish the frequency (or CC) of process for the UE initial connection establishment of execution or connection.PCell is permissible Refer to the community of instruction during handoff procedure.Quenching frequency (or SCC) refers to can join after performing RRC connection establishment The frequency (or CC) put, and can be used for providing other radio resource.PCell and SCell may be collectively termed as servicing little District.Therefore, to its do not configure CA or do not support CA, the UE that is in RRC_CONNECTED (RRC connection) state, only exist The Serving cell being only made up of PCell.Meanwhile, UE that it is configured with CA, that be in RRC_CONNECTED state, Can there is one or more Serving cell, and all of Serving cell can include a PCell and one or more SCell.But, in future, Serving cell can be allowed to include multiple PCell.For CA, except starting initial safe activation During connection establishment after process outside the PCell of initial configuration, network can also for support CA UE configure one or Multiple SCell.But, even if UE supports CA, network can also only configure PCell for UE, and does not increase SCell.PCell can To be referred to as main CC, grappling CC or main carrier, and SCell can be referred to as assisting CC or subcarrier.

In multi-carrier systems, BS can launch to UE in given one or more communities (or one or more CC) Multiple data cells, and UE can launch the ack/nack signal for multiple data cells in a subframe.UE is permissible Allocated one or more communities (or DL CC) are for receiving the PDSCH for DL data receiver.RRC signaling can be passed through It is semi-statically configured or reconfigures the community (or one or more DL CC) for UE.Furthermore, it is possible to by L1/L2 (matchmaker Body access control (MAC)) control signaling dynamically activate/disable the community (or one or more DL CC) for UE.Cause This, the maximum quantity of the ACK/NACK bit will launched by UE changes according to the community (or DL CC) that can be used for UE.That is, The maximum quantity of the ACK/NACK bit launched by UE is configured by RRC/reconfigures, or by L1/L2 signaling along with swashing The DL CC one or more Serving cells of configuration (or) that lives and change.

Figure 15 describes the concept of the MAC layer multiple carrier waves of management in BS.Figure 16 describes a MAC layer in UE Manage the concept of multiple carrier wave.

Seeing Figure 15 and Figure 16, a MAC layer manages one or more frequency carriers to perform to launch and receive.Because Continuous print is needed not to be, so more flexible resource management is possible by the frequency carrier of a MAC layer management.At Figure 15 and 16 In, for convenience, a physical layer (PHY) represents a CC.Here, a PHY does not necessarily means that independent radio frequency (RF) device. Generally, independent RF device represents a PHY but is not limited to this.One RF device can include several PHY.

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

In addition to structure as shown in figures 15 and 16, multiple MAC layer rather than a MAC layer can control multiple CC, if Figure 17 is to as shown in 20.

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

Being applicable to the system of description above is to support a carrier wave to the system of many carrier waves of N, and carrier wave can be Continuous or discrete carrier wave, and unrelated with UL/DL.TDD system is configured to manage N number of carrier wave, and each carrier wave includes DL Launch with UL, and FDD system is configured in UL and DL use multiple carrier wave respectively.FDD system can be supported asymmetric CA, wherein, the quantity of the polymerization carrier wave in UL with DL and/or the bandwidth of carrier wave are different.

If the quantity of the CC of polymerization is equal to the quantity of CC of polymerization in DL in UL, then can configure CC and make to own CC compatible with the CC used in conventional systems.But, the CC not supporting compatibility is not got rid of from the present invention.

For convenience of description, although launching corresponding to PDCCH on DL CC#0 when launching PDCCH on DL CC#0 PDSCH hypothesis under provide explanation, but it is clear that intersection carrier dispatching can be applied so that at the DL different from DL CC#0 PDSCH is launched on CC.

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

Figure 21 is shown in PUCCH format 1a in the case of normal CP and 1b, and Figure 22 is shown in the situation of extension CP Under PUCCH format 1a and 1b.Identical control letter is repeated on a timeslot basis in the subframe of PUCCH format 1a and 1b Breath.The different cyclic shifts (CS) (frequency domain code) of constant amplitude 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) is launched Ack/nack signal.OC includes such as Walsh/DFT orthogonal code.If the quantity of CS is the quantity of 6 and OC is 3, the most permissible Based on individual antenna multiplexing 18 UE altogether in Same Physical Resource Block (PRB).Any time domain (FFT modulate after) or Arbitrarily application orthogonal sequence w0, w1, w2 and w3 in frequency domain (before FFT modulates).The PUCCH format 1 and PUCCH launched for SR Form 1a with 1b is identical in timeslot-level structure, and different in modulation scheme.

(RRC) signaling can be controlled by radio resource and distribute the PUCCH resource being made up of CS, OC and PRB to UE, Launch for SR and feed back for the ACK/NACK for semipermanent scheduling (SPS).As described in reference to Figure 12, for dynamically ACK/NACK (or the ACK/NACK for impermanent scheduling) feedback or the ACK/NACK for the PDCCH of instruction SPS release are anti- Feedback, it is possible to use index with the minimum CCE of corresponding for PDSCH or PDCCH PDCCH discharge for SPS and implicitly divide to UE Join PUCCH resource.

Figure 23 is shown in the scene launching UCI in the wireless communication system supporting CA.For convenience of description, in this example In it is assumed that UCI is ACK/NACK (A/N).But, UCI can include control information, such as CSI (such as, CQI, PMI and RI) With scheduling request information (such as, SR), and do not limit.

The asymmetric CA of Figure 23 illustrative exemplary, wherein, 5 DL CC are linked to single UL CC.Can be from launching regarding of UCI Point arranges this asymmetric CA.That is, the DL CC-UL CC for UCI associates the DL CC-UL can being set to for data CC associates difference.For convenience, if it is assumed that each DL CC can carry until two code words, and for each CC The quantity of ACK/NACK depend on that the maximum quantity of code word set by each CC is (such as, if BS sets for specific CC Putting until two code words, even if specific PDCCH only uses a code word on this CC, the ACK/NACK for this CC is arranged to 2, i.e. the maximum quantity of the code word on this CC), then at least two UL ACK/NACK bit is needed for each DL CC.? In the case of Gai, at least 10 ACK/NACK bits be needed to launch the number for receiving on 5 DL CC on single UL CC According to ACK/NACK.If also indicating that discontinuous transmitting (DTX) state for each DL CC, then need at least 12 bits (=5⁶=3125=11.61 bit) to launch for ACK/NACK.Because can obtain straight in conventional PUCCH format 1a and 1b To two ACK/NACK bits, so this structure can not launch the ACK/NACK information of increase.Although CA is given increase UCI The example of cause of quantity, but this situation be also likely to be due to antenna quantitative increase and TDD system and in The existence of the backhaul subframe in system that continues and occur.It is similar to ACK/NACK launch, when launching with multiple on single UL CC During the control information that DL CC is correlated with, the amount of control information to be launched also increases.Such as, to multiple CQI/ relevant for DL CC The transmitting of PMI/RI information can increase UCI payload.

In fig 23, UL grappling CC (the main CC of also referred to as UL PCC or UL) is the CC launching PUCCH or UCI thereon, and And can by community specifically/UE specifically determines.It addition, DTX state can explicitly be fed back, or can be made by feedback Identical state must be shared with NACK.

Hereinafter, the method that will propose to be used for effectively launching the UCI of increase with reference to accompanying drawing.Specifically, it is proposed that be used for Launch the new PUCCH format/signal processing operations/resource allocation methods of the UCI increased.By the present invention propose new PUCCH format is referred to as CA PUCCH format or relative to the PUCCH in the PUCCH format 2 defined in tradition LTE version 8/9 Form 3.The technical characteristic of the PUCCH format proposed can be easily applied to can in the same manner or in a similar manner Any physical channel (such as, PUSCH) of transmission UCI.Such as, embodiments of the invention are applicable to emission control information periodically Cycle PUSCH structure or aperiodic ground emission control information PUSCH structure aperiodic.

Following situation will be focused on describe the drawings and Examples of the present invention: use PUCCH format 1/1a/ of tradition LTE The UCI/RS symbolic construction of 1b (normal CP) is used as the subframe/timeslot-level UCI/RS symbolic construction to PUCCH format 3 application. But, for convenience, exemplarily define the subframe/timeslot-level UCI/RS symbolic construction of PUCCH format 3, and the present invention It is not limited to such ad hoc structure.UCI/RS symbol can be freely changed in the PUCCH format 3 of the present invention according to system design Number quantity and position.It is, for example possible to use the R/S symbol structure of PUCCH format 2/2a/2b of tradition LTE defines according to this The PUCCH format 3 of one embodiment of invention.

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

Figure 24 to 27 diagram is for feeding back PUCCH format structure and the signal processing operations thereof of multiple ACK/NACK bit. Such as, when feeding back multiple ACK/NACK bit in multicarrier environment, it is possible to use PUCCH format.Such PUCCH format PUCCH format 3 can be referred to as, it to be distinguished with the conventional inline of PUCCH format 1 and 2.

Figure 24 to 27 illustrates PUCCH format structure based on DFT.According to PUCCH structure based on DFT, PUCCH is by DFT Precoding, and apply time domain OC in SC-FDMA level to it before transmission.Hereinafter, PUCCH format based on DFT is referred to as 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 bits) chnnel coding, and Produce coded-bit (or code word) b_0, b_1 ..., b_N-1.M is the size of information bit, and N is the big of coded-bit Little.This information bit includes UCI, such as multiple ACK/ of the multiple data (or PDSCH) for receiving on multiple DL CC NACK.Here, combined coding information bit a_0, a_1 ..., a_M-1, and with the type/number of the UCI of configuration information bit/ Size is unrelated.Such as, if information bit includes the multiple ACK/NACK for multiple DL CC, then for whole bit information Perform chnnel coding rather than chnnel coding is performed for each DL CC or each single ACK/NACK bit.Pass through Chnnel coding produces single code word.Chnnel coding includes, but are not limited to repetition, simplex coding, Randt's Miller (RM) volume Code, perforation RM coding, tail biting convolutional encoding (TBCC), low-density checksum (LDPC) coding or turbo coding.Although not showing Go out, it is contemplated that order of modulation and stock number and coded-bit can be carried out rate-matched.This rate-matched function is permissible Partly covered in channel coding blocks, or realized in single functional device.Such as, channel coding blocks can be by closing Perform (32,0) RM coding in multiple control information and obtain single code word, and circular buffering rate-matched can be performed.

Manipulator passes through 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.Modulation scheme is performed by changing the amplitude launching signal and phase place.Modulation scheme includes example Such as n phase-shift keying (PSK) (n-PSK) and n quadrature amplitude modulation (QAM) (wherein, n is the integer of two or more).Specifically, modulation scheme bag Include 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.Modulation symbol is divided into the rank of time slot/ Pattern/scheme is not limited to specific one.Such as, divider can start sequentially will adjust from the first modulation symbol (localized approach) Symbol processed is divided into time slot.In this case, modulation symbol c_0, c_1 ..., c_L-1 can be assigned to time slot 0, and adjust Symbol c_L/2 processed, c_L/2+1 ..., c_L-1 can be assigned to time slot 1.When modulation symbol is divided into time slot, permissible Interweave (arrangement) modulation symbol.For example, it is possible to distribute the modulation symbol of even-numbered to time slot 0, and can distribute to time slot 1 The modulation symbol of odd-numbered.Can sequentially exchange modulation treatment and division process.

DFT precoder performs DFT precoding (such as, 12 DFT) about the modulation symbol being divided into time slot, in order to Produce multicarrier waveform.See Figure 24, to the modulation symbol c_0 of time slot 0 distribution, c_1 ..., c_L/2-1 by DFT precoding be DFT symbol d_0, d_1 ..., d_L/2-1, and to the modulation symbol c_L/2 of time slot 1 distribution, c_L/2+1 ..., c_L-1 quilt DFT precoding is DFT symbol d_L/2, d_L/2+1 ..., d_L-1.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 extension DFT precoding.Extended code (sequence) is used Perform the time domain at SC-FDMA symbol level to extend.Extended code includes quasiorthogonal code and orthogonal code.But quasiorthogonal code includes not limiting In pseudo noise (PN) code.Orthogonal code includes, but are not limited to walsh code and DFT code.Although for convenience of description orthogonal code being retouched State the typical case for extended code, but orthogonal code can be replaced with quasiorthogonal code.The maximum of extended code size or SF by Limit for controlling the quantity of the SC-FDMA symbol of the transmitting of information.Such as, if four SC-FDMA symbols are for one Control information in individual time slot is launched, then can use orthogonal code w0 of length 4, w1, w2, w3 in each time slot.SF table Show 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 require and change into 1,2,3,4 ....SF can be predefined between BS and UE, or BS can pass through DCI or RRC signaling To indicate SF to UE.Such as, if perforation for control in the SC-FDMA symbol of information one to launch SRS, then there is reduction The extended code of SF (such as, SF=3 rather than SF=4) the control information in corresponding time slot can be applied to.

The subcarrier being mapped among PRB from the signal of operation above generation, and when being converted into by IFFT Territory signal.To time-domain signal plus CP, and launch produced SC-FDMA symbol by RF end.

Each operation will be more fully described under the hypothesis that ACK/NACK is launched for 5 DL CC.If each DL CC can launch two PDSCH, then the ACK/NACK bit for this PDSCH can be 12 bits, including DTX state.? Under the hypothesis of the time extension of QPSK and SF=4, the size (after rate-matched) of encoding block can be 48 bits.Encoding ratio Spy is modulated to 24 QPSK symbols, and QPSK symbol is divided into two time slots, and each time slot includes 12 QPSK symbols Number.12 QPSK symbols in each time slot are converted into 12 DFT symbols by 12 DFT.In each time slot 12 QPSK symbols use the extended code of SF=4 to be extended to four SC-FDMA symbols in the time domain, and then reflected Penetrate.Because launching 12 bits [2 bit x 12 subcarrier x 8SC-FDMA symbol] is upper, thus encoding rate be 0.0625 (= 12/192).If SF=4, then can be with most four UE of each PRB multiplexing.

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

In addition to UCI SC-FDMA symbol and the quantity of RS SC-FDMA symbol and position, with described in reference diagram 25 Identical mode performs basic signal processing operations.Can at the front end of DFT precoder application extension block in advance.

In fig. 25, RS can use and those the identical structures used in LTE system.For example, it is possible to circulation moves Position basic sequence.The multiplexing capacity of data division due to SF=5 but 5.But, by CS interval delta_shift ^PUCCHDetermine RS The multiplexing capacity of 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 data Part multiplexing capacity due to SF=5 but 5, but RS part multiplexing capacity at Δ_shift ^PUCCHIn the case of be 4.Therefore, Overall multiplexing capacity can be limited to the smaller 4 of the two value.

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

Overall multiplexing appearance can be increased by extending to the SC-FDMA symbol level described in RS application reference Figure 24 and 25 Amount.See Figure 26, by applying Walsh to cover (or DFT code covers) in time slot, multiplexing capacity is doubled.Then, multiplexing Even if capacity is at Δ_shift ^PUCCHIn the case of be also 8, be therefore prevented from data division multiplexing capacity reduce.In fig. 26, [y1y2]=[1 1], [y1 y2]=[1-1] or its linear transformation (such as, [j j] [j j], [1 j] [1 j] etc.) are permissible OC for RS.

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

In the case of not applying timeslot-level frequency hopping, again will by applying Walsh to cover in units of time slot Multiplexing capacity doubles.As set forth above, it is possible to [x1 x2]=[1 1], [1-1] or its conversion are used as OC.

As reference, the operation that processes of PUCCH format 3 is not limited to the order shown in Figure 24 to 27.

Channel assignment

Channel assignment refers to by selecting specific resources from multiple resources and the expression of the customizing messages that carries out/send out Penetrate.Common Channel assignment is the scheme being launched customizing messages by the combination of resource and constellation.

Here, resource can be specified by physical time-frequency resource and/or sequence resources (such as, CS value).Example As, in LTE version 8PUCCH form 1/1a/1b, can be selected by the combination of OC, CS and physical resource unit (PRU) Specific resources.It can be assumed that distinguished the multiple resources performing Channel assignment thereon by the combination of three kinds of resources above. It is, for example possible to use the channel selecting method shown in following table 3.

[table 3]

Superincumbent table 3 neutralizes in the following description, is expressed as a, b, the value of c ... can represent by channel Ch- The constellation value that modulation (such as, BPSK, QPSK etc.) in x (x=1,2,3 ...) causes.Or, it is expressed as a, b, c ... Value can be allocated sequence or allocated code multiplexing, the value scrambling or covering rather than constellation value.Accordingly, with respect to Ch- X is expressed as a, b, the value of c ... can be the value that can distinguish betwixt, and be not intended to for distinguishing between these values Method.Especially, in the following description, for convenience of description, be expressed as a about Ch-x, b, the value of c ... are referred to as Modulation value.

It addition, be expressed as a, b, the value of c ... can be predetermined particular values rather than 0.Such as, a can be '+1 ', And b can be '-1 '.

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

In table 3, it is shown that do not use the simple examples of the constellation mapping of complexity, but other constellation can be used to reflect Penetrate for launching more information.Table 4 is shown with the two kinds of example distinguishing constellation mapping (such as, BPSK).

[table 4]

In superincumbent table 4, a, b and c can be in addition to the particular value outside 0.Note, it is preferred that b and c is at constellation On away from each other.Such as, a is used as '+1 ', and, b and c can be, respectively, used as '+1 ' and '-1 ' or be, respectively, used as '-1 ' and '+1 '.In the example of table 4, ACK/ACK is transmitted in resource 1 (channel 1) and launches the value being modulated to b, and And ACK/NACK is transmitted in resource 1 (channel 1) launches the value being modulated to c.It addition, be transmitted in money for NACK/ACK Source 2 (channel 2) launches the value being modulated to b, and NACK/NACK is transmitted in resource 2 (channel 2) to launch is modulated Value for c.

That use in tradition LTE version 8/9 defined in table 5,6 and 7 shown in below, in TDD for ACK/ The mapping relations of the Channel assignment that NACK launches.In LTE version 8/9, TDD ACK/NACK multiplexing can have and TDD The implication that ACK/NACK Channel assignment is identical, but they support system (such as, LTE-A or LTE version at following multicarrier 10) there is in different implications.

In following table 5,6 and 7, in a tdd system, K:{k can be indexed by DL relevant episode₀,k₁,…k_M-1(as Defined in the table 12 described later) determine value M.Such as, if M=2 in table 5, then two PUCCH resourceWithAnd the QPSK constellation in each PUCCH resource ' b (0), b (1) ' may be used for launching two kinds The ACK/NACK information of type, including space binding (that is, the ACK/NACK for multiple code words bundlees).

Specifically, UE uses PUCCH format 1b in ACK/NACK resource in subframe nUpper transmitting bit ' b (0),b(1)’.Can be by producing value ' b (0), b (1) ' and ACK/NACK money according to the Channel assignment of table 5 below, 6 and 7 SourceTable 5,6 and 7 is shown respectively the ACK/NACK multiplexing as M=2, M=3 and M=4 and launches.If ' b (0), b (1) ' be 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 for the HARQ ACK/NACK/ of i-th (0≤i≤3) data cell DTX result.DTX represent be not launched for the data cell of corresponding HARQ-ACK (i) or UE be also not detected by with The data cell that HARQ-ACK (i) is corresponding.In this specification, it is interchangeably used HARQ-ACK with ACK/NACK.Can be right Most four PUCCH resource (that is, n are taken in each data cell⁽¹⁾ _PUCCH,0To n⁽¹⁾ _PUCCH,3).By from the PUCCH taken The PUCCH resource selected in resource launches the ack/nack signal of multiplexing.In table 5,6 and 7, n⁽¹⁾ _PUCCH,xInstruction is used In the PUCCH resource that actual ACK/NACK launches, and ' b (0) b (1) ' instruction is by the two of selected PUCCH resource transmitting Individual bit, it is used QPSK to modulate.Such as, if UE is as being successfully decoded four data cells, then UE in table 7 By being connected to n⁽¹⁾ _PUCCH,1PUCCH resource come to BS launch (1,1).Because the combination of PUCCH resource and QPSK symbol is not All obtainable ACK/NACK can be represented, so in addition in some cases, NACK and DTX is coupled and (is expressed as NACK/DTX)。

Meanwhile, in LTE-A (or the LTE version 10) system that the present invention is suitable for, about being used for applying channel selecting method Channel assignment mapping relations have no particular limits.For example, it is possible to definition being used for as shown in table 8 to 10 launches ACK/ The Channel assignment mapping relations of nack message.Table 8 defines the mapping relations for 2 bit ACK/NACK, table 9 define for The mapping relations of 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 relations for 1 bit to 4 bit ACK/NACK as shown in table 11 can be defined.? In the example of table 11, a channel resource h0 and the constellation value 1 and-1 produced by data modulation may be used for launching 1 bit ACK/NACK information.For the transmitting of 2 bit ACK/nack message, use two channel resource h0 and h1 and constellation value 1 ,-1 ,- J and j.For 3 bit ACK/nack message, use three channel resources h0, h1 and h2 and the constellation produced by data modulation Value 1 ,-1 ,-j and j.Four channel resources h0, h1, h2 and h3 and the constellation value 1 produced by data modulation ,-1 ,-j and j permissible For launching 4 bit ACK/nack message.

[table 11]

The UL ACK/NACK in multicarrier support system, DL launched

In multicarrier system or CA support system, DL resource can be defined as DL CC, and UL resource can be determined Justice is UL CC.It addition, the combination of DL resource and UL resource can be referred to as community.If configuration DL CC and UL asymmetrically CC, then community can only refer to DL CC (or UL CC).Such as, if configuring specific UE with a Serving cell, then exist An one DL CC and UL CC.But, if configuring specific UE with two or more Serving cells, then exist and counting DL CC that Liang Shangyu community is equal and quantitatively equal to or less than the UL CC of DL CC.When configuring with multiple Serving cells During particular UE, can support that the quantity of wherein UL CC is more than the multicarrier environment of the quantity of DL CC.

Can be by indicating the carrier frequency in DL and UL resource (in community in the system information of DL transmitted on resources Frequency of heart) between association.For example, it is possible to configure DL resource and the combination of UL resource by the association defined by SIB2.

According to definition above, CA can refer to the set with two or more communities of different carrier frequencies.That is, Wherein with have different carrier frequencies two or more Serving cells configure specific UE situation can be referred to as CA ring Border.For supporting that the UE, one or more SCell of CA can be polymerized with PCell to support the bandwidth increased.

In this case, Serving cell can be PCell or SCell.For not supporting that CA is in RRC_CONNECTED UE in state, only exists the Serving cell including PCell.It is in RRC_CONNECTED simultaneously for be configured with CA UE in state, Serving cell refers to include the set of one or more communities of PCell and SCell.

PCell is the center cell controlling related communication in CA environment in the Serving cell of configuration.PCell is by UE The community indicating or using in initial connection establishment process, connection reconstruction process or handoff procedure.In LTE-A version 10, UE only can receive on its PCell and launch PUCCH.In following version, may allow on the SCell of UE PUCCH launches.It addition, UE can perform monitoring process, obtain for the only system information on PCell and change.For CA Support that UE, BS can use and only include the RRCConnectionReconfiguration message of mobilityControlInfo Changed by handoff procedure.

It follows that SCell refers to the community in the Serving cell configured in CA environment in addition to PCell.? In LTE-A version 10, SCell does not exist PUCCH.If adding SCell, then BS can be by dedicated signaling to supporting CA UE provide and operate relevant all system informations on the SCell of RRC_CONNECTED state.For SCell, permissible By performing to believe in system via the release of the SCell of a RRCConnectionReconfiguration message and interpolation Change on breath.BS can launch to UE has the special of the parameter different from the parameter that the broadcast on SCell includes Use signaling.After initial safe activation process, BS can be for UE except PCell be (as service during connection establishment process The community of cell configuration) outside also configure that one or more SCell.PCell is provided for safety and inputs and higher level system System information, and SCell is provided for other DL resource, and UL resource is provided as necessary.BS can use bag Include or do not include that the RRCConnectionReconfiguration message of mobilityControlInfo connects weight by RRC Newly configured process is added independently, is eliminated or correct SCell.

In CA environment, PhyCellId, SCellIndex can be defined as the relevant ginseng of RRC with ServCellIndex Number/information element (IE).PhyCellId can have the integer that scope is from 0 to 503, and is used as the physics of community Layer identifier.SCellIndex can have the integer that scope is from 1 to 7, and is used as the identifier of SCell. ServCellIndex can have the integer that scope is from 0 to 7, and is used as Serving cell (PCell or SCell) Identifier.The ServCellIndex with value 0 can be applied to PCell, and for SCell, can apply SCellIndex.That is, the community with the minimum in ServCellIndex (or minimum) cell index 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.Specifically UE can have the Serving cell of one or more configuration.If there is the Serving cell of multiple configurations, have the most in the cell The community of minimum ServCellIndex is PCell, and other communities are SCell.In LTE-A version 10, if at TDD Middle UE has the Serving cell of multiple configuration, then the UL subframe being formed in frame and the UL-DL configuration of DL subframe can be all In community identical, and, can be the most identical according to UL-DL configuration HARQ-ACK timing, this HARQ-ACK timing Indicate which UL subframe for launching the ACK/NACK for the PDSCH launched in specific DL subframe.In following version, If UE has the Serving cell of multiple configuration in TDD, then UL-DL configuration can be different between cells, and according to UL- The HARQ-ACK timing of DL configuration can be different between cells.

It addition, UE can in predetermined C C to BS launch that measure from one or more CC, such as CSI (includes CQI, RI, PMI etc.) UCI and HARQ ACK/NACK.Such as, if needing multiple ACK/NACK to feed back, then UE can collect The ACK/NACK feedback that receives from PCell DL CC and one or more SCell DL CC (such as, ACK/NACK multiplexing or ACK/NACK bundlees), and a PUCCH can be used anti-to the ACK/NACK collected by BS transmitting in the UL CC of PCell Feedback.

In the present invention, when being launched for multiple ack/nack signal that multiple DL launch by a PUCCH, structure The unit (one or more subframes and/or one or more carrier wave) becoming multiple DL to launch is referred to as bundled window.That is, time domain bundle Tie up the ack/nack signal launched for DL referring to be bundled in multiple subframe.The binding of CC territory refers to be bundled in multiple CC In for DL launch ack/nack signal.Time domain/CC territory binding refers to the use being bundled in multiple subframe and multiple CC In the ack/nack signal that DL launches.Although ACK/NACK can be performed by logic and operation to bundle, but the present invention is not Be limited to this, and can use such as logic or other computings.

It addition, be used for using logical AND (or logic or) computing to come the binding of actual execution time domain and/or the list of CC territory binding Unit can be referred to as actual bundled window.I.e., it is possible to there is one or more actual bundled window in a bundled window.Change Sentence is talked about, and the size of bundled window is equal to or more than the size of actual bundled window.Here, can apply for for a DL The space binding (that is, the ACK/NACK for multiple code words bundlees) of the multiple ACK/NACK bits launched, and and bundled window Or actual bundled window is unrelated.

Presently describe the example of ACK/NACK DL launched at defined in 3GPP LTE system, needs.Here, work as 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, can be for table 1 Each UL-DL configuration provides DL relevant episode index K:{k₀,k₁,…k_M-1}。

[table 12]

In fdd, M always 1, and K always meets { k₀}={ 4}.When launching in subframe n in subframe n-k DL launch ACK/NACK time, DL in subframe n-k launches one or more that can correspond to following three situation.

Situation 1 is when needing for by the one of one or more PUCCH instruction of detection in one or more subframes n-k During the ACK/NACK feedback of individual or multiple PDSCH.Here, k ∈ K, and K configures according to subframe index n and UL-DL and changes, And including M element { k₀,k₁,...k_M-1}.Table 1 below 2 shows K:{k₀,k₁,...k_M-1}.Situation 1 relates to requirement and leads to One or more PDSCH of normal ACK/NACK feedback.In the following description, situation 1 is referred to as the ' ACK/ for PDSCH NACK ' or ' for having the ACK/NACK ' of the PDSCH of PDCCH.

Situation 2 is one or more for indicate the DL SPS in one or more subframes n-k to discharge when needing When the ACK/NACK of PDCCH feeds back.Here, k ∈ K, and K represents the index identical with the explanation provided in situation 1.Feelings The ACK/NACK of condition 2 represents the ACK/NACK feedback of the one or more PDCCH for discharging for SPS.Meanwhile, right when performing When the ACK/NACK feedback of DL SPS release, do not perform the ACK/NACK of one or more PDCCH that instruction SPS is activated Feedback.In the following description, situation 2 is referred to as the ' ACK/NACK ' for DL SPS release PDCCH.

Situation 3 is when needing the ACK/NACK feedback of the transmitting for one or more PDSCH, without at one Or the corresponding one or more PDCCH detected in multiple subframe.Here, k ∈ K, and K represents and is given with in situation 1 Explanation in identical index.Situation 3 is about not having the PDSCH of PDCCH, and represents PDSCH's for being distributed by SPS ACK/NACK feeds back.In the following description, situation 3 is referred to as the ' ACK/NACK ' for DL SPS PDSCH.

In the following description, there is the PDSCH of the PDCCH of correspondence, the PDSCH discharged for DL SPS and there is no correspondence The PDSCH of the PDCCH DL that is collectively referred to as needing ACK/NACK to launch launch.

This when the ACK/NACK launched for DL above is applied to multicarrier system described in detail below Bright example.

For convenience of description, the example of the present invention will be described under following hypothesis.But, embodiments of the invention are not It is limited to following hypothesis.

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

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

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

(4) PDSCH (=SPS PDSCH) of the PDCCH not having correspondence can only be there is on PCell.

(5) can support from PCell to the cross scheduling of one or more SCell.

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

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

In the explanation of the present invention, time domain binding and/or the binding of CC territory represent logic and operation.However, it is possible to by all As the additive method of logic or computing etc. performs time domain binding and/or the binding of CC territory.That is, time domain binding or the binding of CC territory refers to It is in the ACK/NACK response using single PUCCH format, by the multiple ACK/NACK tables in multiple subframes or CC The method reaching ACK/NACK information for having less bit.In other words, time domain binding or the binding of CC territory refer to for by M Any means that ACK/NACK information representation is N-bit (M >=N) of bit.

In the system that multicarrier and/or TDD are applied to, can be by using PUCCH format 1a/1b, PUCCH format The Channel assignment of 3 or the Channel assignment of use PUCCH format 3 launch multiple ACK/NACK bit.For for PUCCH format PUCCH resource index, it is possible to use implicit expression maps, explicit mapping or the combination that implicitly and explicitly maps.Implicit expression maps permissible Use and draw, for minimum CCE index based on corresponding PDCCH, the method that PUCCH resource indexes.Explicit mapping can make Predetermined concentration is being configured by RRC with indicating by the ACK/NACK resource indicator (ARI) in PDCCH or draw The method of PUCCH resource index.

Related to the present inventionly, (such as, retouch to 27 with reference to Figure 24 when the format for launching multiple ACK/NACK bit The PUCCH format 3 stated) time, it is substantially based on explicit resource distribution and performs the resource distribution of PUCCH format 3.

Specifically, the UE being configured to PUCCH format 3 can be used for by explicitly assigning (such as, by RRC signaling) The orthogonal resource of this form.Furthermore it is possible to configured by RRC in predetermined orthogonal resource by for launching on SCell PDSCH PDCCH in the ARI value of DCI format determine final PUCCH resource.In this case, ARI can by with Make based on the skew of PUCCH resource value explicitly transmitted with signal, or can serve to indicate that and to use one or more PUCCH resource concentrate which.

In order to comprise ARI information in PDCCH, it may be considered that reuse the word defined with DCI format of existing PDCCH Section carrys out the method for ARI purpose.PDCCH can include that launching power controls (TPC) field.The original purpose of TPC field is Control the transmitting power of PUCCH and/or PUSCH, and can be made up of 2 bits.

As it has been described above, when only launching ARI on SCell, can by the TPC field in the PDCCH on SCell again As ARI.Meanwhile, the TPC field in the PDCCH on PCell may be used for the transmitting power control of PUCCH and/or PUSCH System.

In LTE version 10 system, because the PDCCH of the PDSCH for dispatching PCell can not be received on SCell (that is, not allowing to carry out the intersection carrier dispatching of the PDSCH of PCell from the PDCCH of SCell), so UE only receives on PCell Implication to PDSCH can be equal to UE and only receive the implication of PDCCH on PCell.

Can perform as follows to be distributed by the explicit ACK/NACK resource of RRC signal deployment.

First, the PDCCH corresponding with PDSCH on SCell (that is, for dispatching the PDCCH of PDSCH) can include using The information (such as, ARI) of specific PUCCH resource is drawn in the resource configured from one or more RRC.

If it follows that not receiving the PDCCH corresponding with PDSCH on SCell and only receive on PCell PDSCH, then can apply one of following situation.It is possible, firstly, to use in the PUCCH resource defined in LTE version 8 (i.e., PUCCH format 1a/1b).Second, the PDCCH corresponding with PDSCH on PCell can include for from one or more RRC The resource of configuration draws the information (such as, ARI) of specific PUCCH resource.

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

By this way, when being only to launch on SCell by ARI information definition, if UE is at multicarrier and/or TDD System only receives the one or more PDSCH for PCell (or only receiving one or more PDCCH on PCell), Then because UE not can know that the ARI information launched from SCell, the most not can determine that the PUCCH format for be used by UE The final resource index of (PUCCH format 3).

Even if the present invention being designed to solve problem above proposes for only receiving for PCell as UE The final money for PUCCH format is determined during individual or multiple PDSCH (or only receiving one or more PDCCH on PCell) The method of source index.

In the various examples of the present invention, for convenience of description, wherein UE only receive for PCell one or more The situation (or wherein UE only receives the situation of one or more PDCCH on PCell) of PDSCH is called that ' only PCell connects for short Receive '.Here, the reception about UE defines only PCell reception.If the present invention is applied to multicarrier environment, then UE can have There are a community configured or the community of multiple configuration.If UE has the community of a configuration, Ze Gai community can be PCell, and if UE there is the community of multiple configuration, Ze Gai community can be by a PCell and one or more SCell structure Become.The present invention can be applied to one of both of these case or two kinds of both situations.I.e., only PCell reception condition can be answered Use CA environment and non-CA environment.

And, as set forth above, it is possible to by new PUCCH format, i.e. PUCCH format 3 is for for leading in a tdd system The ACK/NACK crossing the DL transmitting that multiple DL subframe receives launches, even if when UE includes the community that configures.When UE includes During the community of multiple configurations, it is also possible to use PUCCH format 3 in FDD or TDD system.I.e., it is possible at CA system or non-CA TDD system uses PUCCH format 3.

And, in the various examples of the present invention, the candidate resource collection for PUCCH format 3 can be configured by RRC.Can Determine or from the value of this ARI information with the value by ARI information (the reusing of TPC field of PDCCH can be expressed as) Draw the specific PUCCH resource in PUCCH resource Candidate Set.In brief, RRC configuration resource candidate in from The ARI that PDCCH includes draws PUCCH format 3 resource to be used by UE.When as described above by the PDCCH on SCell TPC field (2 bit size) reuse when expressing ARI, ARI has the size of X bit, and X can be defined It is 2.It is, for example possible to use 2 bit A RI express a resource of four PUCCH resource candidates.

The convenience of the explanation in order to be associated with the application of PUCCH format 3, by needing the single of an orthogonal resource Antenna performs to describe the present invention under the hypothesis launched.It may be evident, however, that the invention is not restricted to this, even and if when to PUCCH format During the multi-antenna emission diversity scheme that 3 apply such as orthogonal space resource transmitting diversity (SORTD), the principle of the present invention is also with phase Same mode is suitable for.

Now, the exemplary hypothesis of the present invention distributed for PUCCH format 3 resource is described based on description above.

Resource for PUCCH format 3 can be expressed asAnd four orthogonal moneys for PUCCH format 3 Source candidate can be expressed asWithArbitrarily UE can pass through RRC signaling quilt Assign such four orthogonal resources.RRC signaling can be such as four single RRC signals.A RRC signaling can be passed through The set being made up of four orthogonal resources is notified to UEIt has been assigned The UE of four PUCCH resource candidates can provide at four PUCCH based on finally being determined by the value of the ARI instruction additionally received A PUCCH resource in the candidate of source

The example resource allocation for PUCCH format 3 that table 1 below 3 is shown in single-antenna transmission.

[table 13]

Hereinafter, various embodiments of the present invention are described in detail based on description above.

Embodiment 1

The present embodiment 1 relates to (i.e., only receiving the one or more PDSCH's for PCell in only PCell reception condition Situation or on PCell, only receive the situation of one or more PDCCH) under use predefined resource to distribute method.

In the case of only PCell receives, it is possible to determine the resource index of PUCCH format 3.That is, receive at non-only PCell In the case of, from the ARI received on SCell, UE can show that PUCCH resource indexes, and in only PCell receives, UE is permissible Predetermined PUCCH resource is used to index.

Specifically, new index can be made a reservation for so that UE can determine will use in the case of only PCell receives PUCCH format 3 resource.New index can have the implication identical with the ARI on SCell.In other words, this index is permissible For instruction by any one of the resource Candidate Set of RRC signal deployment.Can be with the shape of predefined rule (or particular value) Formula limits index, and this predefined rule (or particular value) is for indicating the resource (example of the particular sorted in resource Candidate Set As, first resource or last resource).

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

Figure 28 is to be shown in the predefined resource distribution determined in the case of only PCell receives for PUCCH resource Flow chart.

In step S2810, UE can be received by higher level configuration (such as, RRC signaling) and include for PUCCH lattice The PUCCH resource Candidate Set of four resources of formula 3

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

In step S2830, UE can use by the TPC field in one or more PDCCH of SCell again Indicated ARI is used to calculate/select to be used by a PUCCH resource (i.e., from four PUCCH resource candidates One resource index).

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

After step S2830 or step S2840, UE can use the resource corresponding with the index being calculated/selecting to pass through PUCCH format 3 launches ACK/NACK information.

Embodiment 2

The present embodiment 2 relate to a kind of for make a reservation for other resource index and use this other resource index come for Situation about receiving at only PCell (i.e., only receives the situation of the one or more PDSCH for PCell or only connects on PCell Receive the situation of one or more PDCCH) under PUCCH resource distribution method.

In the case of only PCell receives, it is possible to the other resource index of predetermined PUCCH format 3.That is, UE can be From the ARI received on SCell, non-only PCell show that PUCCH resource indexes in the case of receiving, and UE can be at only PCell Predetermined other PUCCH resource index is used in the case of reception.Predetermined index in superincumbent embodiment 1 is for right In the predetermined index of one of the PUCCH resource candidate of UE configuration, and embodiment 2 different from embodiment 1: predetermined and for The other resource index that the PUCCH resource candidate of UE configuration separates.

According to this embodiment, such as, if using 2 bit A RI and defining the resource candidate of four RRC configuration Set, then can transmit an other resource candidate by RRC signaling to UE signal.Then, the resource of RRC configuration is waited Selected works include 5 PUCCH resource index, and one of them predetermined resource index (such as, last index) can be by It is defined as only using under only PCell reception condition.Or, can define discretely with four PUCCH resource candidates and be used for The resource candidate that only PCell receives.In both above both situations, only PCell can be only used for UE distribution and connect The reservation resource index (that is, the resource index do not specified by the ARI on SCell) of receipts situation.Here, whilst it is preferred that Not by be used for only PCell receive an other resource candidate overlapping with the resource candidate that four existing RRC configure, But overlap can be allowed in some cases.

Figure 29 is to be shown under only PCell reception condition the other predefined resource distribution determined for PUCCH resource Flow chart.

In step S2910, UE can be received by higher level configuration (such as, RRC signaling) and include for PUCCH lattice The PUCCH resource Candidate Set of four resources of formula 3

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

In step S2930, waiting from 5 the most regular four predetermined PUCCH resource of PUCCH resource candidate The person's of choosing (such as, four low index PUCCH resource WithIn), UE can use logical That crosses the TPC field in one or more PDCCH of SCell reuses indicated ARI from four PUCCH resource candidatesCalculate/select a PUCCH resource to be used by.

Meanwhile, because not receiving PDCCH in step S2940 on SCell, so UE can be according to predefined rule Select a PUCCH resource.This predefined rule could be for selecting from the PUCCH resource candidate of 5 RRC configurations Last resourceRule.Can limit and will not be used for determining 5 PUCCH resource times in step S2930 The rule of four in the person of choosing is heavy for determining the rule of in 5 PUCCH resource candidates with in step S2940 Folded.But, in some cases it may restrictive rule makes to select overlapping resource candidate.

After step S2930 or step S2940, UE can use the resource corresponding with the index being calculated/selecting to pass through PUCCH format 3 launches ACK/NACK information.

Embodiment 3

Embodiment 3 is directed to use with downlink allocation index (DAI) and is used for (i.e., only receiving in only PCell reception condition For the situation of one or more PDSCH of PCell or on PCell, only receive the situation of one or more PDCCH) under The method of PUCCH resource distribution.

In above-described embodiment 1 and 2, it has been described that for drawing in only PCell receives for PUCCH format 3 Resource index and the method that do not uses other physical layer signaling (such as, PDCCH signaling).Embodiment 3 relate to a kind of definition and The method of the information of the function being able to carry out ARI used in the physical layer signal of reception on PCell, although as existing Scheme can not receive on SCell ARI like that, owing to there is not PDCCH on SCell.Specifically, this embodiment relates to And use the DAI information that includes at PDCCH as the method for ARI information under only PCell reception condition.

Define the DAI field in PDCCH in a tdd system, and assign about DL distribution (or PDSCH scheduling) DAI.When UE launches the ack/nack signal for multiple DL assignment (PDSCH) in a UL subframe, can draw from DAI About the information of the quantity of DL assignment (PDSCH), (PDSCH) ack/nack signal to be launched is assigned for this DL.Such as, UE is worked as When BS launches ack/nack signal (the using ACK/NACK binding) for multiple DL assignment (PDSCH), wherein UE fails to connect The situation of the part receiving (that is, loss) multiple PDCCH is likely to occur.Now, transmitted to because UE not can know that , it is possible that there is mistake in ACK/NACK produces in the situation of the PDSCH corresponding with the PDCCH of reception failure.Can use DAI solves such problem.In existing TDD system, such as, a UL subframe corresponds to N number of DL subframe wherein In the case of, if sequentially assigning (i.e., sequentially counting) DAI to the PDCCH launched in N number of DL subframe, then UE can pass through DAI information in PDCCH knows whether and has been correctly received previous PDCCH.

In this embodiment, it is contemplated that when using PUCCH format 3, the DAI in the PDCCH of PCell is not used in former The situation of beginning purpose, it is proposed that DAI is re-used as determining the ARI that PUCCH resource assigns.Specifically, even if at TDD System uses PUCCH format 3, also without DAI information in the operation as the full multiplexer mode of ACK/NACK, at ACK/ The full multiplexer mode of NACK does not perform time domain binding or CC territory (or frequency domain) binding.Therefore, DAI field can be re-used as using In the ARI that only PCell receives.

Figure 30 is to be shown in DAI field under only PCell reception condition with acting on showing of ARI that PUCCH resource determines The flow chart of example.

In step S3010, UE can be received by higher level configuration (such as, RRC signaling) and include for PUCCH format The PUCCH resource Candidate Set of four resources of 3

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

In step S3030, UE can use again making by the TPC field in one or more PDCCH of SCell Calculate/select to be used by a PUCCH resource (that is, with indicated ARI from four PUCCH resource candidates Resource index).

Meanwhile, in step S3040, because not receiving PDCCH on SCell, thus UE can use by DAI field in the PDCCH of PCell reuse that indicated ARI to select from four PUCCH resource candidates will be by Its PUCCH resource (that is, one resource index) used.

After step S3030 or step S3040, UE can use the resource corresponding with the index being calculated/selecting to pass through PUCCH format launches ACK/NACK information.

Embodiment 3-1

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

The terms bundled subframe (or bundled window) used in the explanation of the present invention represents when by a UL PUCCH Launch when the ACK/NACK for the DL subframe in bundled window responds a unit being made up of DL subframe rather than actually The unit of binding is performed in time domain or CC territory (or frequency domain).

Such as, in LTE version 8TDD system, as superincumbent table 12 (shows that DL relevant episode indexes K:{k₀,k₁,… k_M-1) shown in, give about using which previous one or more DL subframe (subframe n-k) to launch for specific (the definition of the ACK/NACK response that the DL in subframe n) launches of UL subframe.Described in binding subframe by the example of table 12, when When specific UL subframe being launched for the ACK/NACK response of the DL transmitting in one or more specific DL subframes, this Or multiple specific DL subframe is referred to as bundling subframe.Such as, in UL-DL configuration 4, the binding subframe for UL subframe 2 is DL Subframe 12,8,7 and 11, and be DL subframe 6,5,4 and 7 for the binding subframe of UL subframe 3.

If in TDD use PUCCH format 3, then can as described above by a UL PUCCH launch for The ACK/NACK response that DL in multiple DL subframes launches.Here, when according to embodiment 3 under only PCell reception condition many When individual DL subframe detects one or more PDCCH, if the ARI indicated by corresponding PDCCH (or DAI) value is different, then Do not know which ARI value is for calculating/select PUCCH resource.

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

Embodiment 3-2

Embodiment 3-2 relates to the example applying identical ARI value in the CC of binding.This embodiment can also be employed To only PCell reception condition, this only PCell reception condition can include following situation: wherein, UE can not detect at one or DL on multiple SCell launches and only receives DL on PCell and launches, although BS is at PCell and one or more Perform DL on SCell to launch.

The terms bundled subframe (or bundled window) used in the explanation of the present invention represents when by a UL PUCCH Launch for the DL CC in bundled window ACK/NACK respond and with binding in the presence/absence of time unrelated by DL CC structure The unit become rather than the unit actually performing binding in time domain or CC territory (or frequency domain).Such as, as application ACK/ During the full multiplexing of NACK, the CC of binding can have the implication identical with the quantity of the CC configured for UE.

If using PUCCH format 3 in TDD or FDD system, then can occur in which as mentioned above by a UL When PUCCH launches the ACK/NACK response for multiple DL CC.Here, ' launch the ACK/NACK for multiple DL CC Response ' implication may indicate that exist in PCell and one or more SCell DL launch.Now, if PCell's ARI value in PDCCH is different from the ARI value in the PDCCH of SCell, then unclear which ARI value of use calculates/selects PUCCH resource.

Therefore, in order to prevent problem above, it should be maintained on PCell the field (DAI for ARI purpose in the same manner Field) value and on SCell for the value of field (TPC field) of ARI purpose.

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.Cause This, in addition to ARI value except being maintained on PCell and SCell in PDCCH is equal, be maintained in the PDCCH in multiple subframe ARI value equal.

Embodiment 4

Embodiment 4 relates to a kind of use TPC field and comes for (i.e., only receiving for PCell in only PCell reception condition The situation of one or more PDSCH or on PCell, only receive the situation of one or more PDCCH) under PUCCH resource divide The method joined.Embodiment 4 can be applied to wherein apply or do not apply two kinds of situations of the full multiplexing of ACK/NACK.Embodiment 4 Can also be applied to wherein apply or two kinds of situations of not application space binding (bundling for the ACK/NACK of multiple code words).

In superincumbent embodiment 3, it has been described that for even determining PUCCH resource (example in only PCell receives Such as, the resource of PUCCH format 3) resource index and the method that do not uses other physical layer signaling.Embodiment 3 relates to working as DAI Be not used as during original applications (for the purposes of the index that DL distribution (or PDSCH scheduling) sequentially assigns) using DAI come for The example of ARI purpose.Therefore, when using PUCCH format 3 in a tdd system, if support time domain binding or CC territory (or frequency Territory) binding, then DAI information needs for original purpose, in order to produce correct ACK/NACK information.

Therefore, in example 4, under only PCell reception condition, DAI is not used in other purposes.The present embodiment 4 proposes A kind of side that under only PCell reception condition, the TPC field in the one or more PDCCH on PCell is re-used as ARI Method.

(that is, SCell exists PDCCH to launch) under non-only PCell reception condition, as it has been described above, on SCell TPC field 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, on PCell according to pre-defined rule determine one or more TPC field in specific PDCCH may be used for original transmitting power and controls purpose, and one or more other PDCCH TPC field may be used for ARI purpose.UE can be used only on PCell according to pre-defined rule determine one or more The TPC field of specific PDCCH to control purpose for original power, and it is one or more to receive other on PCell During PDCCH, the TPC field of the PDCCH of one or more correspondences can be construed to ARI by UE.

If TPC field is not used in original purpose, then UE possible loss includes the TPC field for power control PDCCH, if or BS do not dispatch PDCCH, then may slightly reduce and launch the dynamic controlling that determines of power for the UL of UE Energy.But, the TPC value in PDCCH is not absolute value but for the previous relative deviant launching power.And, i.e. UE is made TPC value not updated once or twice, it is also possible to keep the transmitting power preset.Except using the TPC in PDCCH Outside the transmitting Poewr control method of field, the Poewr control method that also provides for supplementing (this deviates the scope of the present invention, and because of This, will not be described in detail).Therefore, the loss of TPC value does not has considerable influence for network performance.

In the application present invention, can use according to the TPC field of the pre-defined rule one or more PDCCH on PCell In original purpose (power control purpose).Hereinafter, the example of pre-defined rule will be described.

As the first example, can be by the TPC field definition of the PDCCH launched in the n-th subframe of binding subframe for using In original purpose.Here, n could be for indicating the value of one or more subframes of part in binding subframe.Such as, if One of instruction binding subframe, then can be defined as n for instruction the 0th subframe or the value of last subframe.Furthermore, it is possible to root N is differently determined according to the quantity (or size of binding subframe) of binding subframe.In the way of similar shown in table 12, The quantity of binding subframe can be such as 1,2,3,4 or 9.Or, different number can be bundled according to the binding scheme of new definition The subframe of amount.And, n may indicate that the set of the multiple subframes in binding subframe.Such as, when n is 0 and 1, at binding The TPC field of the PDCCH launched in the 0th and the 1st subframe in frame may be used for original purpose.Therefore, if n has multiple Value, then will be increased the quantity of n value by the quantity receiving the PDCCH tested for rollback described below.Such as, if n has Have two values, then being received the quantity for the PDCCH of rollback test should be 2.Following illustrative theory in the present invention In bright, for convenience of description, n has a value.

As the second example, the TPC field having in the PDCCH of the n-th DAI value in binding subframe can be defined as For original purpose.Here, n can be 0,1,2,3 .... one of.Or, if DAI value is construed to 1,2,3,4 ..., N then can be defined as 1,2,3,4 .... a value.In this case, even if in the full multiplexer mode of ACK/NACK (wherein Do not apply the situation that time domain or CC territory (or frequency domain) bundle) in, it is also possible to the one or more PDCCH on PCell include DAI field.Furthermore, it is possible to determine n with the form of the set of multiple values.Such as, when n is 0 and 1, this may indicate that at tool There is the TPC field in the PDCCH of zero-sum the oneth DAI value for original purpose.Or, when DAI value is construed to from the beginning of 1 Time, 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 Purpose.Therefore, when n has multiple value, increased n by the quantity of the PDCCH of the rollback test received for describing later The quantity of value.Such as, if n has two values, then being received the quantity for the PDCCH of rollback test should be 2.At this In the description below of invention, for convenience of description, n has a value as example.

In superincumbent second example, DAI value can represent with dibit size to UE distribute for one or more Continuous (sequentially) enumerator of PDCCH.The value of the actual transmission of DAI field can be can be construed to DAI value 1,2,3 and by UE One of 0,1,2 and 3 of 4 (or 00,01,10 and 11 when being expressed as 2 bit value).By the DAI value about actual transmission It is described below with the DAI value explained by UE.

The value of the actual transmission of DAI field can be 0,1,2 or 3, and this value can be construed to first, second by UE, 3rd or the 4th PDCCH.In this case, about the DAI value of actual transmission, the n=0 in particular UE is (0,1,2 and 3 In set) instruction the oneth PDCCH.

The value of the actual transmission of DAI field can be 0,1,2 or 3, and this value can be construed to first, second by UE, 3rd or the 4th PDCCH.In this case, about the DAI value explained by UE, the n=1 in particular UE is (1,2,3 and 4 In set) instruction the oneth PDCCH.

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

As described in the above example, at one or more PDCCH of the n-th subframe or the DAI=n that determined by the value of n One or more PDCCH in TPC field for original purpose (power control), and at other one or more PDCCH In TPC field can be re-used as ARI.

Figure 31 is to be shown in TPC field under only PCell reception condition with acting on showing of ARI that PUCCH resource determines The flow chart of example.In the example of Figure 31, it is assumed that the TPC field of the specific PDCCH determined according to predefined rule for Original purpose, and the TPC field of other one or more PDCCH is re-used as ARI.

In step S3110, UE can be received by higher level configuration (such as, RRC signaling) and include for PUCCH format The PUCCH resource Candidate Set of four resources of 3

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

In step S3130, UE can use again making by the TPC field in one or more PDCCH of SCell Calculate/select to be used by a PUCCH resource (that is, with indicated ARI from four PUCCH resource candidates Individual resource index).

Meanwhile, in step S3140, UE may determine that whether the quantity of received PDCCH is 1.Because when at SCell On perform step S3140 when not receiving PDCCH, so what the quantity instruction of the PDCCH received received on PCell The quantity of PDCCH.If (that is, the quantity of the PDCCH received on PCell is the determination result in step S3140 in order being 1), then perform step S3150, and if determination result in step S3140 be no (that is, reception on PCell The quantity of PDCCH is more than 1), then perform step S3160.

In step S3150, if UE only receives a PDCCH on PCell, then UE can use the TPC of PDCCH Field is used for original purpose (power control), and because not having any other PDCCH, does not receives so UE may determine that ARI value.In this case, limit UE to run under traditional LTE version 8 pattern.This can be referred to as in fall-back mode Run.It is identical that fall-back mode launches operation with the ACK/NACK of PUCCH format 1a/1b using usual definition, and therefore, will Description is omitted.The quantity about the PDCCH received in step S3140 be whether 1 determination can be referred to as Rollback is tested, where it is determined whether application fall-back mode.

Meanwhile, because performing step S3160 when the quantity of the PDCCH received on PCell is more than 1, so UE is permissible The TPC field in one of PDCCH is used to be used for original application target, and can be by the TPC of other one or more PDCCH Field is construed to for ARI.Then, UE can use and reuse indication by the TPC field in the PDCCH of PCell The ARI shown calculates/selects to be used by a PUCCH resource (that is, one resource from four PUCCH resource candidates Index).

After step S3130 or step S3160, UE can use the resource corresponding with the index being calculated/selecting to pass through PUCCH format 3 launches ACK/NACK information.

In the examples shown of Figure 31, under following hypothesis, give explanation: UE only checked and received (or detection) The quantity of PDCCH, and when the quantity of the PDCCH received is 1, the TPC field of corresponding PDCCH is for original mesh 's.

But, if the quantity of the PDCCH received is 1, then the TPC field of PDCCH may be used for original purpose or can To be reused for ARI purpose.Therefore, when the quantity of the PDCCH received is 1, the most always it is carried out fall-back mode operation, and Preferably, detailed determination is performed.

Figure 32 be shown in only PCell receive in the case of by TPC field with acting on the ARI that PUCCH resource determines The flow chart of another example.In the example of Figure 31, it is assumed that according to the TPC of the specific PDCCH that predefined rule determines Field is used for original purpose, and the TPC field of other one or more PDCCH is re-used as ARI.

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

Perform (that is, when the quantity of the PDCCH received on PCell is 1) when the determination result of step S3240 is for being Step S3250.In step S3250, determine whether this PDCCH received is predefined PDCCH (that is, PDCCH Whether TPC field is for original purpose).For example, it may be determined that whether the PDCCH received is the first subframe in binding subframe In PDCCH.As another example, it may be determined that whether the PDCCH received is to have DAI value 1 (following, DAI=1) PDCCH.If it is determined that result is yes, then performs step S3260, and if it is not, then perform step S3270.

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

Step S3270 can be performed when the result of step S3240 is no.That is, if the quantity of the PDCCH received is big In 1, then as it is assumed that only exist one, wherein TPC field is for the PDCCH of original purpose, so UE can identify at least one The TPC field of PDCCH is re-used as ARI.UE can use the ARI value of the TPC field of self-corresponding PDCCH to come at four PUCCH resource candidate calculates/selects a PUCCH resource (that is, one resource index) to be used by.

When the determination result of step S3250 is no, it is also possible to perform step S3270.If that is, the PDCCH received Quantity be 1, then because corresponding PDCCH is not that wherein TPC field is for the PDCCH of original purpose, so UE can identify The TPC field of the PDCCH going out correspondence is reused for ARI.UE can use the ARI of the TPC field of self-corresponding PDCCH Value calculates/selects to be used by a PUCCH resource (that is, one the resource rope in four PUCCH resource candidates Draw).

In step S3270, UE can use the resource corresponding with the index being calculated/selecting to come by PUCCH format 3 Launch ACK/NACK information.

Embodiment 4-1

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

The terms bundled subframe (or bundled window) used in the explanation of the present invention represents when by a UL PUCCH The unit being made up of DL subframe when launching for the ACK/NACK response of the DL transmitting in the DL subframe in bundled window, Rather than in time domain or CC territory (or frequency domain) actual perform binding unit.

Such as, in LTE version 8TDD system, as superincumbent table 12 (illustrates that DL relevant episode indexes K:{k₀,k₁,… k_M-1) shown in, give about which previous one or more DL subframe (subframe n-k) for launching at specific UL Subframe (the definition of the ACK/NACK response of the DL wireless communication system in subframe n).By the example of table 12, binding is being described In subframe, when launching the ACK/NACK launched for the DL in specific one or multiple DL subframe in specific UL subframe During response, this specific one or multiple DL subframe be referred to as bundling subframe.Such as, in UL-DL configuration 4, for UL subframe 2 Binding subframe be DL subframe 12,8,7 and 11, and, the binding subframe for UL subframe 3 is DL subframe 6,5,4 and 7.

If in TDD use PUCCH format 3, then can as described above by a UP PUCCH launch for The ACK/NACK response that DL in multiple DL subframes launches.Here, according to the above embodiments 4, in the situation that only PCell receives Under in multiple DL subframes, detect multiple PDCCH.If by having indicated by the PDCCH of the TPC field being re-used as ARI ARI (or TPC) value is different, and the most ambiguous, which ARI value is used for calculating/select PUCCH resource.

Here, be confirmed as the PDCCH of the TPC field for original purpose such as except having according to predefined rule, There is the PDCCH of DAI=1) outside, the PDCCH with the TPC field being re-used as ARI can correspond to PDCCH (example As, there is the PDCCH of DAI value (hereinafter referred to as DAI > 1) more than 1).

Therefore, in order to prevent this problem, it should be equally maintained at binding subframe on PCell launch, have by It is re-used as the PDCCH of the TPC field of ARI (that is, in addition to having for the PDCCH of the TPC field of original purpose PDCCH) 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 terms bundled used in the explanation of the present invention represent with binding in the presence/absence of Unrelated, when being launched the ACK/NACK response for the DL CC in bundled window by a UL PUCCH, by DL CC The unit constituted rather than the unit actually performing binding in time domain or CC territory (or frequency domain).Such as, application is worked as During the full multiplexing of ACK/NACK, the CC of binding can have the implication identical with the quantity of the CC configured for UE.

If using PUCCH format 3 in TDD or FDD system, then can send out as described above by a UL PUCCH Penetrate the ACK/NACK for multiple DL CC to respond.Here, the implication launching the ACK/NACK response for multiple DL CC is permissible Corresponding to wherein there is the situation that DL launches on PCell and one or more SCell.Now, if be used as having ARI value in the PDCCH of the TPC field of the ARI on PCell is different from the ARI value in the PDCCH on SCell, then obscure not Clear, which ARI value is used for calculating/select PUCCH resource.

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

Here, can equally be maintained on PCell, with except being determined using TPC field according to predefined rule Carry out the PDCCH outside original purpose PDCCH (such as, there is the PDCCH of the DAI=1) PDCCH of 1 (such as, there is DAI >) ARI value and 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.

That is, (such as, a bundle is become when multiple CC and multiple subframe when considering the above embodiments 4-1 and 4-2 simultaneously When tying up unit), if the ARI value in corresponding community or corresponding subframe is different, then calculating/select PUCCH resource may It is ambiguous.Therefore, it should the ARI being equally maintained in the PUCCH on PCell and SCell, and simultaneously, it should The ARI being equally maintained in the PDCCH in multiple subframe.

Here, on PCell, can equally keep for except being determined to use TPC word according to predefined rule Section come PDCCH outside the PDCCH (such as, there is the PDCCH of DAI=1) for original purpose (such as, there is DAI > 1 PDCCH) ARI value.

Figure 33 is that diagram uses TPC field for original purpose or the reality of ARI purpose according to the DAI value on PCell Execute the figure of example.

DAI field value is used as the stored counts device of the PDCCH of each community.That is, each a community of DAI value Individual PUCCH is sequentially increased 1.The most always in all of subframe, there is PDCCH.

In the examples shown of Figure 33, on PCell, first and the 3rd, subframe exists the PDCCH for DL distribution. DAI value is 0 in the PDCCH of the first subframe, and is 1 in the PDCCH of the 3rd subframe.On SCell, distributing for DL PDCCH in sequentially provide DAI value.In fig. 33, it is illustrated that DAI value 0,1,2,3,0,1,2,3 ..., but from the viewpoint of UE See, these values have with DAI value 1,2,3,4,1,2,3, the identical implication in 4 ....

With above-described embodiment 4 relatively, according to the DAI value on PCell, the TPC field in PDCCH may be used for former Beginning purpose or ARI purpose.Such as, the DAI value on PCell is the PDCCH of 0 (or being 1 in terms of the viewpoint of UE) wherein TPC field, i.e. the TPC field in PDCCH in first subframe of PCell in fig. 33 is used for original purpose (that is, power Control), and the TPC field in another PDCCH on PCell is reused for ARI purpose.

With in the above embodiments 4-1 to 4-3 relatively, can equally be maintained at binding subframe and/or binding community In ARI value.Such as, if application bundle window, then UE on four subframes in the examples shown of Figure 33 and five communities Can assume that the value of the TPC field (that is, for the TPC field of ARI purpose) of PDCCH on PCell and SCell is identical, remove Outside TPC field in first subframe of PCell (wherein, DAI is 0).

Embodiment 5

Embodiment 5 relates to (i.e., only receiving the feelings of the one or more PDSCH for PCell in only PCell reception condition Condition or on PCell, only receive the situation of one or more PDCCH) under use TPC field to come the side for PUCCH resource distribution Method.Embodiment 5 is applied to the binding of part ACK/NACK.Part binding refers to the most in the time domain or in CC territory (or frequency domain) Binding.

DAI field is essentially available for original purpose (that is, in each community as in superincumbent embodiment 4 On the stored counts device of PDCCH), and the TPC field in PDCCH can be re-used as ARI.In this case, in advance The TPC field of fixed specific PDCCH is used for original purpose.The n-th son specific PDCCH can being defined as in binding subframe The PDCCH (describe this part in the embodiment 4 having been described above, and therefore, the repetitive description thereof will be omitted) of frame.Or, Can determine that wherein TPC field is for the PDCCH of original purpose based on DAI value.

The above example of Figure 31 or 32 can be applied to embodiment 5 as basic operation with being substantially the same, and saves The repeat specification be given in the embodiment 4 slightly having been described above.

Hereinafter, TPC field is used to be used for original purpose when applying the binding of part ACK/NACK based on DAI value description Or the method detailed of ARI purpose.

First, the TPC field in the PDCCH with the n-th DAI value in the binding subframe of PCell can be defined as For original purpose.The value of DAI field can be given 0,1,2,3 ... or can be given 1 in terms of the viewpoint of UE, 2、3、4、...。

In this case, ACK/NACK part tie-in mode (being applied to time domain binding or CC territory (or frequency domain) binding) In, DAI field can be included by the one or more PDCCH on PCell.Here, should determine based on pre-defined rule The value of the DAI field that one or more PDCCH of PCell include, and the present invention explained below to its build in detail View.

When applying ACK/NACK part binding, if the TPC field in the PDCCH of DAI=n is for original purpose (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, DAI instruction is to the accumulated value of the PDCCH of UE distribution, and if simply DAI to multicarrier environment application DAI, then can be used as the accumulation of the PDCCH distributed on whole communities (or CC) to UE by ground Value.Such as, as shown in Figure 34, when in four sub-frames and applying ACK/NACK to bundle on two CC, it may be determined that DAI Value makes the DAI value side that CC index increases in bundled window be increased up.However, it is difficult to the program to be applied to part bundle Tie up.Therefore, configure wherein in the LTE version 10TDD pattern of multiple CC (or community), it is desirable to provide another kind is used for determining The method of DAI value.

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

As example, DAI value may indicate that the cumulative number in multiple subframes of each community to the PDCCH of UE distribution Amount (Figure 35 (a)).Such as, such method for determining DAI value it is preferably used when application bundle in the time domain.Permissible The cumulative amount of PDCCH is applied in the way of PDCCH in the counting all subframes in a radio frame.Or, can With to count the side of the PDCCH in actual bundled window (for actually performing the unit of ACK/NACK binding) in the time domain The cumulative amount of formula application PDCCH.In the example of Figure 35 (a), by the reality of the unit of four subframes on SCell#2 The DAI in the PDCCH in three subframes in bundled window is defined as 0,1 and 2, and this is to use DAI field to be used as tiring out The example of long-pending enumerator, this stored counts device is a PDCCH, the 2nd PDCCH and the 3rd for indicating the PUCCH of correspondence respectively PDCCH。

As another example, DAI value may indicate that distributes to UE in each subframe on multiple CC (or community) The sum (Figure 35 (b)) of PDCCH.Such as, it is preferably used such DAI value when application part binding in CC territory to determine Method.The quantity of the PDCCH sum of PDCCH can being defined as in all CC that UE is configured.Or, can be by In the actual bundled window (performing the unit of ACK/NACK binding for reality) that the sum of PDCCH is defined as in CC territory The quantity of PDCCH.In the example of Figure 35 (b), the DAI value in the PDCCH in the first subframe is 2, and this is to use DAI Field is used as indicating the example that the sum of the PDCCH in corresponding subframe is the designator of 3.

Or, to the PDCCH of UE distribution in the multiple CC (or community) DAI value can being defined as in each subframe Stored counts device.Can according in all CC that UE is configured CC index (or cell index) ascending order or according to The ascending order of CC index (or cell index) in the actual bundled window in CC territory, comes for each PDCCH counting PDCCH's Cumulative amount.Such as, in the example of Figure 35 (b), DAI=0 that the DAI value in the 3rd subframe is defined as on PCell, 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 DAI is used as in actual bundled window in the time domain the tired of the PDCCH of distribution Long-pending enumerator (if i.e., reset DAI value on each CC), then can apply use except having on PCell equally Specific DAI value (such as, DAI=0) PDCCH external PCell and multiple SCell on the TPC field of PDCCH come for The embodiments of the invention of ARI purpose.

Meanwhile, as shown in Figure 35 (b), if DAI is used as in the actual bundled window in CC territory (or frequency domain) dividing The sum (or stored counts device) of the PDCCH joined, then be likely difficult to application and use except the specific DAI value having on PCell The TPC field of the PDCCH on the external PCell and multiple SCell of the PDCCH of (such as, DAI=0) carrys out the basis for ARI purpose Inventive embodiment.

For example, it may be assumed that distribute PDCCH to specific UE in the first subframe and the second subframe, and not at SCell Upper distribution PDCCH.Although this situation receives corresponding to only PCell, but the DAI value of the PDCCH received by UE is at the two In frame identical (such as, DAI=0) (if DAI field be used as correspondence subframe in PDCCH sum designator or Stored counts device, then according to above it is assumed that DAI value is 0).Then, ambiguous for UE, determine on PCell The TPC field of which PDCCH in two PDCCH is used for ARI purpose, and the TPC field of which PDCCH is for original mesh 's.In other words, if determining DAI value by the reset schemes of the DAI value of each subframe, then use can not be applied except tool Have specific DAI value (such as, DAI=0) on PCell PDCCH external PCell and multiple SCell on PDCCH TPC field carrys out the embodiments of the invention for ARI purpose.

In order to solve problem above, different DAI values can be applied on PCell and SCell to determine method.Such as, On SCell, DAI is used as in the actual bundled window in frequency domain (or CC territory) stored counts of the PDCCH of distribution Device, and on PCell, DAI is used as in actual bundled window in the time domain the instruction of the sum of the PDCCH of distribution Symbol (or stored counts device).

Or, in order to apply the present embodiment, at least DAI on PCell is defined as PDCCH's in the time domain by needs Stored counts device.Therefore, the DAI of the one or more PDCCH on PCell is used as actual binding window in the time domain The stored counts device of the PDCCH of distribution in Kou, and can come in the way of identical or different with the DAI used on PCell The DAI of the use one or more PDCCH on SCell.

In the example of the present invention explained below, it is assumed that the DAI field of PDCCH is used as follows.

First, the DAI field in PDCCH is used as in the multiple subframes in the binding of each CC is checked dividing The stored counts device of the PDCCH joined.That is, each CC determines DAI value independently.Here, the bit value 0 of DAI field, 1, 2 and 3 indicate respectively stored counts 1,2,3 and 4.That is, in terms of the viewpoint of DAI field, it is expressed as the bit value of 0,1,2 and 3 also may be used To be expressed as 1,2,3 and 4 in terms of the viewpoint from the DAI value explained by UE.

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

Figure 36 to 39 diagram uses the various examples of the DAI field in CC territory bundlees.In the example of Figure 36 to 39, figure Show that 5 CC and the 4DL-1UL in the TDD configuration for UE configuration (that is, is collected for the DL transmitting in four DL subframes ACK/NACK response launches response with the PUCCH by a UL subframe).It addition, in the examples shown of Figure 36 to 39, bundle Tie up window and include 5 CC and four subframes.But, illustrate in Figure 36 is to 39 the largest amount of actual bundled window be 4, The situation of 5 or 2.

Figure 36 diagram does not applies the example of CC territory binding on PCell, and (the actual bundled window in CC territory is Big size is 4).In this case, the DAI field of PCell is used as the accumulation of the PDCCH distributed to the subframe on PCell Enumerator.The DAI field of SCell is used as the designator of the sum of the PDCCH to SCell distribution, except at each Outside PCell in subframe.

Figure 37 diagram does not the most apply the example (largest amount of the actual bundled window in CC territory of CC territory binding on PCell It is 4).In this case, the DAI field of PCell is used as the stored counts device of the PDCCH distributed to the subframe on PCell. The DAI field of SCell is used as in each subframe the instruction of the sum of the PDCCH to PCell and SCell distribution Symbol.Therefore, according to the DAI of SCell, UE is able to know that the sum of the PDCCH distributed by BS in corresponding subframe (that is, exists The sum of the PDCCH on PCell and SCell).UE can use the DAI of PCell and about the PDCCH's distributed The information of sum determines whether there is the PDCCH that UE fails to detect/receive in actual bundled window.Therefore, it is possible to Efficiently perform the CC territory ACK/NACK binding in corresponding subframe.

Such as, in the examples shown of Figure 37, if in the PDCCH detected by UE on SCell in the second subframe DAI value be 2, then UE is capable of identify that on PCell and multiple SCell the sum of PDCCH of distribution is 3.Here, can assume that UE does not receives PDCCH in SCell#2.In this case, it is impossible to only determined by the DAI value on SCell and do not receive To PDCCH be whether PDCCH (that is, on SCell) or in addition to actual bundled window in actual bundled window Window (that is, on PCell) in PDCCH.Because the DAI value on PCell is given stored counts in the time domain, So UE can confirm that is sequentially provided DAI value in first on PCell and the 3rd subframe, and therefore confirm to there is not UE not The PDCCH that can detect on PCell.As a result, UE loses in being able to know that one of PDCCH detection SCell in the second subframe Situation about losing.

Figure 38 diagram wherein independently apply with PCell or SCell example that CC territory bundlees (the actual bundled window in CC territory Largest amount is 5).In this case, the DAI field of PCell is used as the tired of the PDCCH to the subframe distribution on PCell Long-pending enumerator.The DAI field of SCell can serve to indicate that distribution on PCell and SCell in each subframe The sum of PDCCH.Therefore, UE can by the DAI of SCell know the PDCCH distributed by BS in subframe sum ( The sum of the PDCCH in PCell and SCell).Because the quantity of the PDCCH that the instruction of DAI value is in actual bundled window, So UE may determine whether in actual bundled window UE and fails the PDCCH detecting/receiving.Therefore, it is possible to have Effect ground performs the CC territory ACK/NACK binding in corresponding subframe.

It is the situation of 2 that Figure 39 illustrates the largest amount of the wherein actual bundled window in CC territory.Now, PCell does not applies CC territory bundlees, and it is possible to configuration has two actual bundled windows of largest amount 2 on four SCell.The DAI of PCell Field is used as the stored counts device of the PDCCH distributed to the subframe on PCell.The DAI field of SCell is used as removing Outside PCell in each subframe, in actual bundled window in the upper distribution of SCell (most two SCell) The designator of the sum of PDCCH.

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

Therefore, under only PCell reception condition, it is possible to equally keep the wherein TPC on PCell in binding subframe Field is reused for the ARI value of the PDCCH (that is, in addition to wherein TPC is for the PDCCH of original purpose) of ARI purpose.Separately Outward, on the CC of binding, it is possible to be equally maintained at the value of the field (=TPC field) being used for ARI purpose on SCell The value of the upper field (=TPC field) for ARI purpose of PCell.And, on binding CC and subframe, it is possible to equally keep Except being confirmed as using TPC field (such as, to have for the PDCCH of original applications according to predefined rule on PCell The PDCCH of DAI=1) outside the ARI value of the PDCCH PDCCH of 1 (such as, there is DAI >).Ground related to this, superincumbent The principle of the present invention described in 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 UL ACK/NACK launched for the DL SRS in multicarrier support system launches

LTE version 8 system supports SPS.If have activated DL SPS to launch, then can allocate use in advance by PDCCH In the time/frequency resource that SPS launches, and the PDSCH of the PDCCH not having correspondence can be launched by the resource of distribution.

The ACK/NACK feedback relevant to SPS can be divided into two types.One type be launch in subframe n right In ' the ACK/NACK feedback of the PDCCH ' of the DL SPS release that instruction is detected by UE in one or more n-k.Another kind Type is to launch the ACK/ for ' PDSCH not having the PDCCH of correspondence in one or more subframes n-k launches ' in subframe n NACK feeds back.The first type corresponds to following situation: wherein, if there is PDCCH in the n-th-k subframe, (wherein, k can To be one or more values), then in the n-th subframe, launch the ACK/NACK for this PDCCH feed back.The second type corresponds to Following situation: wherein, launches, then if receiving SRS in the n-th-k the subframe do not have other PDCCH after SPS activates The ACK/NACK feedback that corresponding SPS is launched is launched regularly in the n-th subframe.Relevant detailed for launching to SPS Describe in detail bright, be referred to file 3GPP TS 36.213.

Be substantially based on PDCCH CCE index determine in LTE version 8 system for ACK/NACK feedback PUCCH resource indexes.If the ACK/NACK response in a PUCCH in the n-th subframe includes in the n-th-k subframe One or more PDCCH (include general PDCCH and instruction DL SPS release PDCCH) ACK/NACK response, then may be used To show that PUCCH resource indexes from the CCE of PDCCH index.But, if should only launch for not having in the n-th-k subframe There is the ACK/NACK response of the SPS of PDCCH, the most not can determine that the PUCCH resource index for ACK/NACK response.In order to solve Such problem, in LTE version 8 system, is indicated in advance by RRC signaling and ' is not had the PDCCH's of correspondence for only existing PDSCH launches ' the PUCCH resource indexed set of the situation of (that is, SPS PDSCH transmittings) (such as, indexes by four PUCCH resource The set constituted).And, determine whether to use PUCCH to provide by the TPC field in the PDCCH that instruction SPS activates One PUCCH resource of source indexed set.Index in the PUCCH resource for DL SPS defined in the table 14 being shown belowAnd the mapping relations between the value of TPC field.

[table 14]

If performing above-mentioned DL SPS in multicarrier support system to launch, then must provide for launching in view of DL SPS ACK/NACK launching technique.

Each embodiment to this present invention is described under following premise: be similar to the above embodiments 4 and 5, for spy Determine the PCell of UE a PDCCH (have DAI=1 (DAI=1,2,3,4 ...) PDCCH) TPC field for original mesh Power control purpose, and the TPC field of other one or more PDCCH is for ARI purpose.It should be noted that this The hypothesis of sample illustrates that clear, and the application example of the present invention is not limited to this.I.e., it is possible to provided by additive method ARI information.

When launching in the n-th subframe, ' PDSCH not having the PDCCH of correspondence launches ' in the n-th-k subframe is (following Be referred to as ' there is no the SPS ' of PDCCH) ACK/NACK response time, can receive in the n-th-k subframe and there is no the SPS of PDCCH, and And in addition to this it is possible to one PDCCH of detection.Then, need launch for PDCCH ACK/NACK in response to for not having There is the ACK/NACK response of the SPS of PDCCH.If here, a PDCCH detected is that a PDCCH (such as, has DAI The PDCCH of=1), then because the TPC field of PDCCH is for original purpose, so this situation is when UE does not receives ARI information Time.Therefore, UE not can determine that the resource index for PUCCH format 3.Hereinafter, description is used for the basis of the problem above that solves The various embodiments of invention.

In the following description, one of three kinds of situations below need ACK/NACK to launch.In a word, situation 1 be for ' having the ACK/NACK of the PDSCH ' of PDCCH, situation 2 is for ' ACK/NACK of DL SPS release PDCCH ', and situation 3 It is for ' the ACK/NACK of DL SPS PDSCH '.

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

Embodiment 6

Embodiment 6 relates to always use PUCCH format 3 to the method launching ACK/NACK response.

The PUCCH format 3 resource index collection of SPS can be only used for UE instruction by RRC signaling.For example, it is possible to UE There is provided about with the form shown in superincumbent table 13 byWithThe collection constituted The information closed.Furthermore it is possible to specify PUCCH format 3 to be used by the TPC field being used in the PUCCH indicating SPS to activate Which resource index of resource index collection.

As example, when needing the ACK/NACK feedback only for the SPS not having PDCCH, can select and use logical Cross the SPS in the set of RRC configuration and activate specific PUCCH format 3 resource index indicated by PDCCH.I.e., it is possible to use PUCCH format 3 launches the ACK/NACK of the SPS being only used for not having PDCCH.

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

First method is to select and use to activate PUCCH form 3 resource index indicated by PDCCH by SPS.That is, PUCCH format 3 can also be used to launch for ' there is no the SPS ' of PDCCH and ' have the ACK/ of a PDSCH ' of PDCCH NACK responds.

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

' it is PDCCH (such as, the wherein DAI (DAI not including ARI information corresponding to the PDCCH ' of PDSCH when one =1) PDCCH) time, can select and use and activate PUCCH format 3 resource index indicated by PDCCH by SPS.I.e., i.e. Make from ' PDCCH ' corresponding to PDSCH does not gets ARI information, it is possible to use PUCCH format 3 is launched for ' not having The SPS ' of PDCCH and ' there is the ACK/NACK response of a PDSCH ' of PDCCH.

If one ' corresponding to the PDCCH ' of PDSCH be include ARI information PDCCH (such as do not have a DAI (DAI > 1) PDCCH) (should it may is that when UE loss has the PDCCH of a DAI), then use by ' corresponding to PDSCH's PUCCH format 3 resource index of the ARI value indicated by TPC field in PDCCH ' can be chosen and use.

Meanwhile, when transmitting include for ' do not have the SPS ' of PDCCH ACK/NACK multiple ACK/NACK feedback time, can With by by second on PCell or more PDCCH one or more PDCCH of DAI > 1 (such as, wherein) or at one or The ARI value indicated by TPC field of the one or more PDCCH on multiple SCell determines PUCCH format 3 resource index.

Embodiment 7

Embodiment 7 relates to the transmitting that operation does not has the SPS of PDCCH for always ' only ' in fall-back mode The method of ACK/NACK.Here, fall-back mode refers to launch according to the ACK/NACK in the operation defined in LTE version 8, example As, use the ACK/NACK of PUCCH format 1a/1b to launch.On the other hand, about for ' do not have the SPS ' of PDCCH and other DL launches the ACK/NACK of (having the PDSCH of PDCCH) and launches, it is possible to use PUCCH format 3.

To this end, the PUCCH format 1a/1b resource index of ' only ' SPS can be used for launching by RRC signaling to UE instruction Collection.Can configure as shown in table 14 or can be according to other arrangements PUCCH format 1a/1b resource index collection.Work as instruction When SPS activates, which of PUCCH resource indexed set to be used can be specified by the TPC field activated in PDCCH at SPS Index.

Because having preset the time/frequency resource launched for SPS between BS and UE, so BS and UE is aware of when to send out Penetrate and receive for ' there is no the ACK/NACK feedback of the SPS ' of PDCCH.Therefore, in the binding including the SPS for particular UE In window, BS can use the TPC field of all PDCCH to come for ARI purpose, and not between the PUCCH on PCell respectively Distinguish.That is, during the transmitting of the ACK/NACK feedback only for the SPS not having PDCCH, including not having the SPS of PDCCH The one or more PDCCH launched in bundled window can use all of TPC field to come for ARI purpose, and not at PCell And distinguish between multiple SCell.

In this case, the ACK/NACK launching the SPS for not having PDCCH about PUCCH feeds back, the TPC word of PDCCH Section is not used in original purpose (UL launches power and controls).But, the TPC value in PDCCH is to launch power for previous Relatively deviant rather than absolute value, even and if UE by the renewal of TPC value not once or twice, also keep default transmitting merit Rate.In addition to using the transmitting Poewr control method of the TPC field in PDCCH, additionally provide supplementary power controlling party Method.And, when needing the transmitting not having the SPS of PDCCH in fdd mode, limit UE and can not obtain the TPC of original purpose Value.Therefore, even if when not applying the TPC of original purpose, in TDD, the operation described in the above example of the present invention does not shows Write ground and affect network performance.

According to the example of embodiment 7, when needing the ACK/NACK feedback only for the SPS not having PDCCH, Ke Yixuan Select and use the SPS of the set configured by RRC to activate the specific PUCCH format 1a/1b resource index indicated by PDCCH.That is, For being only used for the ACK/NACK not having the SPS of PDCCH, can perform to use the fall-back mode operation of PUCCH format 1a/1b.

As another example, when needing for ' there is no the SPS ' of PDCCH and ' have a PDSCH's ' of PDCCH During ACK/NACK feedback, because that the TPC field of all PDCCH in bundled window is for ARI purpose, so can Select with the ARI value indicated by the TPC field according to the PDCCH by a detection and use PUCCH formatization 3 resource rope Draw.

Meanwhile, when launching multiple ACK/NACK feedback of the ACK/NACK including the SPS for not having PDCCH, because As mentioned above the TPC field of all PDCCH in bundled window is for ARI purpose, it is possible to by by PCell and/ Or one or more ARI values of the TPC field instruction of the one or more PDCCH on SCell determine PUCCH format 3 resource Index.

Embodiment 8

Embodiment 8 relates to one and performs for not having ' including ' SPS of PDCCH to launch in fall-back mode for always The method of the ACK/NACK that DL launches.

To this end, the PUCCH format of the transmitting being used for the SPS that " only " does not has PDCCH can be indicated to UE by RRC signaling 1a/1b resource index collection.Can configure as shown in table 14 or PUCCH format 1a/1b money can be configured according to other schemes Source indexed set.When indicating SPS to activate, PUCCH resource to be used can be specified by the TPC field in activating PDCCH at SPS Which index of indexed set.

According to the example of embodiment 8, when needing the ACK/NACK feedback of SPS not having PDCCH for ' only ', Ke Yixuan Select and use the SPS of the set configured by RRC to activate the specific PUCCH format 1a/1b resource index indicated by PDCCH.That is, For only there is no the ACK/NACK of the SPS of PDCCH, can perform to use the fall-back mode of PUCCH format 1a/1b.Here, it is right ACK/NACK feedback in the SPS not having PDCCH can have the size of 1 or 2 bits according to the quantity of code word, and permissible Use PUCCH format 1a or 1b.

As another example, need for ' there is no the SPS ' of PDCCH and ' there is the ACK/ of a PDSCH ' of PDCCH NACK feeds back, and can select and use the SPS of the set configured by RRC to activate the specific PUCCH format indicated by PDCCH 1a/1b resource index.That is, even for including that the ACK/NACK not having the transmitting of the SPS of PDCCH feeds back, can perform to make By the fall-back mode of PUCCH format 1a/1b.Here, according to for ' there is no the SPS ' of PDCCH and ' there is one of PDCCH The quantity of the code word of each of PDSCH ' and need 2 bits to 4 bit feedback payload (this is because ought non-application space 1 bit ACK/NACK Response field bit is produced about a code word) during binding.

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

Embodiment 8-1

Embodiment 8-1 relates to when needs are not for ' having the SPS ' of PDCCH and ' have the ACK/ of a PDSCH ' of PDCCH The method using the channel selection profile of M=2,3 or 4 during NACK feedback.That is, for ' there is no the SPS ' of PDCCH and ' have The size of the ACK/NACK feedback payload of one PDSCH ' of PDCCH is 2 to 4 bits, and in order to there is no any loss ACK/NACK feedback is launched on ground, can apply the Channel assignment side of 2,3 or 4 PUCCH format 1b (or PUCCH format 1a) of use Case.When use defined in LTE version 8 for the channel selection profile of PUCCH format 1b (or 1a) time, this can be expressed For using the channel selection profile of LTE version 8 to operate under fall-back mode.

In multiple resources of Channel assignment, from ' the CCE index corresponding to the PDCCH ' of PDSCH draws one PUCCH format 1b (or 1a) resource, and another PUCCH format can be indicated by the PDCCH for indicating SPS to activate 1b (or 1a).ACK/ can be launched by selecting the channel selection profile of one of two PUCCH format 1b (or 1a) resources Nack message.

If it addition, need further exist for PUCCH resource (such as, M=3 or 4), then with by " corresponding to PDSCH's PDCCH " PUCCH resource corresponding to the value (CCE index+skew) that obtains plus the skew (such as, 1) of regulation of CCE index May be used for Channel assignment.Replace or supplement based on ' corresponding to the other resource of CCE index of the PDCCH ' of PDSCH, with logical Cross to the skew (such as, 1) of regulation plus being activated the resource index of PDCCH assignment by SPS and PUCCH corresponding to the value that obtains Resource may be used for Channel assignment.

Or, be similar to scheme above, following channel selection profile can be applied, i.e. use from ' there is no PDCCH's SPS ' and ' there is the PUCCH format 1a/1b resource that an information relevant for PDSCH ' of PDCCH explicitly or implicitly determines Index.

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

Because UE can use any one of these three kinds of situations to launch ACK/NACK information, so BS should be above Blind decoding is performed in the case of three kinds.

Embodiment 8-2

Embodiment 8-2 relates to a kind of when needs are not for ' having the SPS ' of PDCCH and ' have a PDSCH's ' of PDCCH During ACK/NACK feedback, using space binding (that is, the ACK/NACK for multiple code words bundlees), it is fixed to use in LTE version 8 The method that PUCCH format 1b (or 1a) of justice uses fall-back mode.

First, when ' when there is no the SPS ' of PDCCH corresponding to the transmitting of multiple (such as, 2) code word, for its ACK/NACK response performs space binding.Similarly, when ' there is a PDSCH ' of PDCCH corresponding to multiple (such as, 2) During the transmitting of code word, perform space binding for its ACK/NACK is responded.If ' there is no the SPS ' of PDCCH and ' have The only one of one PDSCH ' of PDCCH is that a code word is launched and another is that two code words are launched, then only about two Code word transmitting performs space binding.

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

2 bit ACK/NACK can be launched by PUCCH format 1b (or 1a) of tradition LTE version 8 to feed back.That is, if Execution space bundlees, then PUCCH format 1b (or 1a) of LTE version 8 can be used to operate ACK/NACK under fall-back mode anti- Feedback.

In such a case it is possible to select and use that ' the CCE rope corresponding to the PUCCH ' of PDSCH is extractive from one PUCCH format 1a/1b resource index.Or, the SPS that can select and use the resource index by configuring at RRC to concentrate swashs PUCCH format 1a/1b resource index indicated by PDCCH alive.In other words, corresponding ACK/NACK response return back to PUCCH Form 1a, and be re-used by phase place rotation, i.e. one of two ACK/NACK responses are mapped to I channel, and another It 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 PUCCH format 1b used in LTE version 8, highest significant position (MSB) can be mapped to for ' there is no the ACK/NACK of the SPS ' of PDCCH, and least significant bit (LSB) (LSB) can be mapped To for ' there is the ACK/NACK of a PDSCH ' of PDCCH (such as, having the PDCCH of DAI=1).Or, can more than The contrary mode of the example in face maps multiple ACK/NACK.

As another embodiment, for ' ACK/NACK not having the SPS ' of PDCCH is mapped to the I of QPSK constellation Axle, and for ' ACK/NACK of a PDSCH ' with PDCCH (such as, having the PDCCH of DAI=1) can be mapped Q axle to QPSK constellation.Or, multiple ACK/NACK can be mapped in the way of contrary with above example.It addition, according to The sequential received, for ' not having the SPS ' of PDCCH and ' have the ACK/NACK first received of a PDSCH ' of PDCCH It is mapped to I axle, and, the ACK/NACK for reception afterwards can be mapped to Q axle.Or, can be with above The mode that example is contrary maps multiple ACK/NACK.

Such as, when for ' ACK/NACK not having the SPS ' of PDCCH is mapped to I axle and ' has 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 (that is, ' corresponds to The PDCCH ' of PDSCH), then BS can receive the ACK/NACK response at least SPS.This is because, when UE fails to detect During PDCCH, when for ' there is no constellation positions during ACK/NACK mapped segment number I axle of the SPS ' of PDCCH equal to when using PUCCH format 1a uses BPSK constellation (that is, I axle) to launch ' only ' for ' not having the star during ACK/NACK of SPS ' of PDCCH Seat is put.

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

The emission mode that constellation mapping above can be applied equally to wherein in each community is MIMO mould The situation of formula and other situations.Constellation mapping above can also be applied, and unrelated with the binding of the most actually application space (that is, with whether there are 2 code words launch unrelated).

In Application Example 8-2, it might even be possible to ' only ' for not having the ACK/NACK of the SPS of PDCCH to feed back application Space bundlees.In this case, BS should perform blind decoding for following three kinds of situations: for the ACK/ for ' only ' SPS The PUCCH format 1a/1b region of NACK, for for ' there is no the SPS ' of PDCCH and ' have a PDSCH's ' of PDCCH The PUCCH format 1a/1b region of ACK/NACK and PUCCH format 3 region.

It addition, in Application Example 8-2, replace from ' the extractive resource of CCE rope corresponding to the PDCCH ' of PDSCH Index is as PUCCH resource, it is possible to use the SPS of the PUCCH resource collection configured by RRC activates the PUCCH specified by PDCCH Resource index, and other parts can be applied equally.

Embodiment 8-3

Embodiment 8-3 relates to when needs are not for ' having the SPS ' of PDCCH and ' have the ACK/ of a PDSCH ' of PDCCH Application space binding during NACK feedback (that is, the ACK/NACK for multiple code words bundlees) and the channel selection profile of use M=2 Method.When use defined in LTE version 8 for the channel selection profile of PUCCH format 1b (or 1a) time, this can be by It is expressed as using the fall-back mode operation of the channel selection profile of LTE version 8.

First, for ' in the case of there is no the transmitting of multiple (such as, two) code word of the SPS ' of PDCCH, for right Its ACK/NACK response performs space binding.Similarly, for ' have PDCCH a PDSCH ' multiple (such as, Two) in the case of the transmitting of code word, perform space binding for its ACK/NACK is responded.If ' there is no PDCCH's SPS ' and ' one of PDSCH ' with PDCCH be a code word and another be two code words, then only for two codes The transmitting of word performs space binding.

Therefore, for ' there is no the SPS ' of PDCCH and ' there is the ACK/NACK payload of a PDSCH ' of PDCCH Size is by 2 bits when 2 or 4 bits when not performing space binding are reduced to when the binding of execution space.

2 bit ACK/NACK can be launched by PUCCH format 1b (or 1a) of tradition LTE version 8 to feed back.Here, The channel selection profile using the M=2 of PUCCH1b (/ 1a) can be used.I.e., it is possible to use PUCCH format 1b (1a) Fall-back mode launches 2 bit ACK as the result performing space binding/NACK feedback.

Here, M=2 can be denoted as two kinds of ACK/NACK information (2 bit ACK/NACK letter of space binding result Breath) transmitting, or can represent use two PUCCH resource Channel assignment.Therefore, it can by using Channel assignment Improve the detection performance of BS.

In two PUCCH resource of Channel assignment, the first PUCCH resource can use and activate PDCCH by SPS The PUCCH format 1a/1b resource index specified, and the second PUCCH resource can use from ' the PDCCH ' corresponding to PDSCH CCE rope extractive PUCCH format 1a/1b resource index.Contrary with above example, the first and second PUCCH resource can Index and from ' the PDCCH ' corresponding to PDSCH to be respectively mapped to activate the PUCCH resource specified of PDCCH by SPS The extractive PUCCH resource of CCE rope indexes.Can select by selecting the channel of one of two PUCCH format 1b (or 1a) resources Scheme of selecting is to launch ACK/NACK information.

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

Example as this embodiment, it is assumed that provide the channel mapping relations using PUCCH format 1b as shown in table 5. Map for channel two PUCCH resource (WithIn), activate, by SPS, the PUCCH that PDCCH specifies Resource can be mapped toFurther, from ' the extractive PUCCH resource of CCE rope corresponding to the PDCCH ' of PDSCH can To be mapped toMay determine that such map configuration, and with ' there is no the SPS ' of PDCCH and ' corresponding to PDCCH's The reception order (receiving the time) of PDSCH ' is unrelated.Such as, even if when specific UE is losing PDCCH (i.e..' corresponding to PDSCH PDCCH ') and only receive when launching response after SPS, UE can also receive the ACK/NACK at least for this SPS and ring Should.This is because, when UE fails to detect PDCCH, for for ' ACK/NACK not having the SPS ' of PDCCH launches PUCCH resourceWith the PUCCH resource launched for not having the ACK/NACK of the SPS of PDCCH for ' only 'Identical.Meanwhile, as the modified example of this embodiment, can map on the contrary or permissible with above example Order according to the time of reception maps corresponding PUCCH resource and DL emission type (PUCCH or SPS).

As another example of the present embodiment, in the channel mapping relations using PUCCH format 1b, can by for The ACK/NACK of SPS is mapped to the MSB (that is, the ACK/NACK for SPS is mapped to the first bit) of 2 bit ACK/NACK, Further, for ' ACK/NACK of a PDSCH ' with PDCCH (such as, having the PDCCH of DAI=1) can be mapped to LSB (that is, for there is the ACK/NACK of the PDSCH of PDCCH be mapped to the second bit).Or, even if when for SPS's ACK/NACK is mapped to I axle and for ' having a PDSCH's ' of PDCCH (such as, having the PDCCH of DAI=1) When ACK/NACK is mapped to Q axle, UE fails to detect PDCCH (that is, ' corresponding to the PDCCH ' of PDSCH), and BS can also receive To the ACK/NACK response launched at least SPS.This is because work as in the case of PUCCH detects unsuccessfully for ' not having The constellation positions when ACK/NACK of the SPS ' of PDCCH is mapped to I axle uses PUCCH format 1a to use BPSK constellation with as UE (that is, I axle) launch for ' only ' do not have PDCCH SPS ACK/NACK response time constellation positions identical.Or, permissible Configure the mapping relations contrary with above example, and mapping can be performed according to the order of the time received.

In order to ensure that BS receives the ACK/NACK at least for SPS and responds, it is possible to launch in various ACK/NACK feedback In the case of customizing messages is mapped to specific PUCCH resource.For example, it is possible to configurating channel Choose for user relation make for PUCCH resource and the PUCCH launching the ACK/NACK for ' only ' SPS on it that the ACK/NACK of SPS transmitting is mapped to provide Source is identical.

Table 1 below 5 illustrates modulation symbol (or the star for PUCCH format 1a in tradition LTE version 8/9 and 1b Seat).

[table 15]

In table 15, it is assumed that the value ' 0 ' of b (0) be NACK and ' 1 ' be ACK.So, the value ' 00 ' of b (0), b (1) represents ACK/ACK, and ' 11 ' expression NACK/NACK.In this case, at least one preceding bit b (0) has and at PUCCH Modulation symbol identical in form 1a with 1b.In other words, b (0) when d (0)=1 at two PUCCH format 1a and 1b In always 0, and when d (0)=-1 in two PUCCH format 1a and 1b always 1.Therefore, BS can receive and examine Survey the information about at least one preceding bit b (0), even if BS does not knows whether to use PUCCH format 1a or PUCCH format 1b launches received ACK/NACK feedback.Can be with configurating channel Choose for user relation so that for ' there is no PDCCH's The ACK/NACK of SPS ' uses the PUCCH resource being mapped to a previous Bit b (0).Therefore, BS ensure that at least for The reception of the ACK/NACK of SPS.

Such as, interior as M=2, it is possible to use the Channel assignment mapping relations shown in following table 16.

[table 16]

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

For example, it is assumed that only receive the SPS with a code word, and do not receive and ' there is the PDSCH ' of PDCCH.? In the case of Gai, it is possible to use PUCCH format 1a is launched the ACK/NACK for SPS and responded.

Meanwhile, when receiving together with SPS ' when there is the PDSCH ' of PDCCH, it is possible to use select according to the channel of the present invention Select.In this case, the PUCCH resource by configuring in the higher level for SPS is concentrated through indicated by SPS activation PDCCH PUCCH resource be used as table 16It addition, from ' CCE corresponding to the PDCCH ' of PDSCH indexes (by advance Set pattern is the most implicitly) PUCCH resource that draws is used as table 16In this case, BS should be able to receive that ACK/NACK for SPS responds, and whether loses with UE that ' PDCCH ' corresponding to PDSCH is unrelated.

If responded as it has been described above, UE launches the ACK/NACK for SPS, then useHere, ACK corresponds to Wherein b (0)=1 and the modulation symbol of d (0)=-1, and NACK is corresponding to the modulation symbol of wherein b (0)=0 and d (0)=1 Number.Meanwhile, when UE launches for SPS and ' when the ACK/NACK of the PDSCH ' with PDCCH responds, can confirm in table 16 Launch the resource that the ACK/NACK for SPS responds thereon.Use be will now be described in table 16Situation ' ACK, NACK/DTX ' and ' NACK, NACK/DTX '.' ACK, NACK/DTX ' is corresponding to wherein b (0) b (1)=11 and d (0)=1 Modulation symbol, and ' NACK, NACK/DTX ' is corresponding to wherein b (0) b (1)=00 and the modulation symbol of d (0)=1.In a word, Only for SPS ACK/NACK respond transmitting and for SPS and ' have PDCCH PDSCH ' ACK/NACK response Launch in both, launched by identical modulation symbol (that is, the d (0)=-1 for ACK and the d (0)=1 for NACK) UsingACK/NACK launch in for SPS ACK/NACK respond.Therefore, BS can detectOn signal time confirm to respond at least for the ACK/NACK of SPS, and whether have been received by for SPS's with BS ACK/NACK responds or for SPS with ' the ACK/NACK response of the PDSCH ' with PDCCH is unrelated.

Meanwhile, in the case of the situation of ' ACK, the ACK ' in table 16 and ' NACK/DTX, ACK ', it is possible to use from ' right Should be in the extractive resource of CCE rope of the PDCCH ' of PDSCH, i.e. useLaunch ACK/NACK response.Receiving ?On signal time, BS can confirm that and receives for ' not having the SPS ' of PDCCH and ' have the PDSCH's ' of PDCCH ACK/NACK responds.

In the above example, although have been described with PUCCH format 1a for convenience, but the same principle of the present invention PUCCH format 1b can be applied to.

It is, for example possible to use PUCCH format 1b launches ' only ', the ACK/NACK with the SPS of two code words is rung Should.Meanwhile, ' when there is the PDSCH ' of PDCCH, sky can be used according to the example according to the present invention when receiving together with SPS Between bundle.In the case of both above, launch the ACK/ for SPS by same channel (PUCCH resource) and modulation symbol Nack message.More specifically, by application space bundle (such as, logic product), for SPS two code words ACK/ACK, ACK/NACK, NACK/ACK and NACK/NACK become ACK, NACK, NACK and NACK.If launched for SPS and ' tool simultaneously Have the ACK/NACK response of the PDSCH ' of PDCCH, then the ACK/NACK for SPS responds and becomes ACK according to space binding result Or NACK, and respond respectively with the channel for the ACK/NACK of only SP is responded and the ACK/NACK of modulation symbol and NACK/NACK is identical.Therefore, signal is being detectedTime, BS can be according to being at least used for the previous signals of SPS (such as, B (0)) be whether ACK or NACK and be that space bundlees result by ACK/NACK response confirmation, and with BS whether have been received by right Respond or for SPS with ' the ACK/NACK response of the PDSCH ' with PDCCH is unrelated in the ACK/NACK of SPS.

The emission mode that constellation mapping above can be applied equally to wherein in each community is MIMO mould The situation of formula and other situations.Can also apply constellation mapping, and unrelated with the binding of the most actually application space (that is, be No existence 2 code word is launched unrelated).

In Application Example 8-3, it might even be possible to launch for not having the ACK/NACK of the SPS of PDCCH to feed back to ' only ' Application space bundlees.Making comparisons with embodiment 8-1 or 8-2, this situation can reduce wherein should perform blind Detecting by BS The quantity in region.More specifically, in the channel selection profile defined in LTE version 8, for the Channel assignment side of the M of big value Case is made up of the superset of the channel selection profile of the M for little value.Such as, a previous Bit in the Channel assignment of M=2 The transmitting of (such as, b (0)) or only ACK/NACK has and uses the 1 of PUCCH format 1a in the case of not applying Channel assignment Bit ACK/NACK launches identical result.Therefore, when being activated by the SPS for the ACK/NACK for ' only ' SPS PUCCH format 1a/1b resource index indicated by PDCCH is used as when the first resource of Channel assignment indexes, it is possible to Wherein use and distinguish between the situation of Channel assignment and the situation the most not using Channel assignment.In this case, detect right In ' there is no the SPS ' of PDCCH and ' having the ACK/NACK response of the PDSCH ' of PDCCH, detection ' only ' is for SPS's automatically ACK/NACK responds.Therefore, BS can perform blind Detecting in two regions, and these two regions are for for Channel assignment ACK/NACK in PUCCH format 1a/1b resource detects (including that ' only ' detects for the ACK/NACK of SPS) and is used for ACK/NACK detection in PUCCH format 3.

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

Embodiment 8-3-1

As it has been described above, produce ACK/NACK response about three kinds of situations.Situation 1 relates to having corresponding PDCCH's PDSCH, situation 2 relates to indicate the PDCCH of DL SPS release, and situation 3 relates to not having the PDSCH of PDCCH of correspondence. Situation 3 is also referred to as the ACK/NACK of SPS PDSCH.

In the explanation of the present embodiment, for ' PDCCH ' instruction situation 1 or the situation 2, ' SPS of ACK/NACK response PDSCH ' indicates situation 3, and particular UE performs receive for the DL of above three kinds of situations and perform the ACK/ received for DL The operation of NACK illustrates.The ACK/NACK response launched in the n-th UL subframe has in the n-th-k subframe about above Relation (wherein, the k ∈ K, and K:{k that three kinds of situations respond for the ACK/NACK that DL launches₀,k₁,…k_M-1, and reference Table 12).The explanation of ACK/NACK transmitting subframe position will be omitted below.

In this embodiment, do not reduce performance to support the dynamic emission power caused by TPC command, can make With by (defined in LTE version 8 or version 10) of PUCCH format 1a predefined channel selection profile.

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

In this case, the use of TPC field is defined below.

2 bit TPC fields in the PDCCH of DL DAI=1 are for the TPC command of original purpose wherein.

2 bit TPC fields in PDCCH in DL DAI > 1 are used for ARI purpose.UE is it is assumed that DL DAI > 1 wherein In all PDCCH in, ARI value is identical.

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

If UE only receives SPS PDSCH, then use LTE version 8PUCCH form 1a/1b resource (that is, at rollback mould Operation in formula).

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

If UE receives SPS PDSCH and has another PDCCH of DL DAI=1, then use and pass through PUCCH format The predefined channel selection profile (channel selection profile defined in LTE version 8 and version 10) of 1a.Here, by higher Layer configuration determines that the first PUCCH resource is (such as, by being indicated by the ARI of SPS PDCCH in the resource set that RRC configures Resource), and the numbering of a CCE based on the transmitting for corresponding PDCCH (i.e., the wherein PDCCH of DL DAI=1) (or index) determines the second PUCCH resource.

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

Meanwhile, the situation wherein configuring multiple Serving cell is presently described.

Here, the use of TPC field is determined as follows.

The most only on PCell, 2 bit TPC fields in the PDCCH of DL DAI=1 are ordered for the TPC of original purpose Order.

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 purpose.UE supposes in all one or more PDCCH on PCell and one or more SCell, ARI It is worth identical.

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

If UE only receives SPS PDSCH, then use LTE version 8PUCCH form 1a/1b resource (that is, at rollback mould Operation in formula).

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

If UE only receives another PDCCH of SPS PDSCH and wherein DL DAI=1 on PCell, then use logical Cross the predefined channel selection profile (channel selection profile defined in LTE version 8 or version 10) of PUCCH format 1a.? This, by higher level configure (such as, by the resource set that RRC configure by SPS activation PDCCH ARI indicated by resource (seeing table 14)) determine the first PUCCH resource, and, based on for corresponding PDCCH (i.e., wherein DL DAI=1 The numbering (or index) of the oneth CCE of transmitting PDCCH) 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, ' PDCCH ' instruction situation 1 relevant to ACK/NACK response or situation 2, and ' SPS PDSCH ' indicates situation 3, as described in superincumbent embodiment 8-3-1.Term ' has PDSCH ' or ' tool of DAI=1 The PDSCH ' having DL DAI > 1 refers to by being 1 corresponding to the DL DAI indicated by the PDCCH of PDSCH or being more than 1.Below will Omit ACK/NACK and launch the explanation of subframe position.

If UE receives SPS PDSCH and has the PDCCH of DL DAI=1, then because there is no ARI information, so UE Not can know that available PUCCH resource.In order to solve this problem, it may be considered that method below.

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

If UE only receives SPS PDSCH has DL DAI > 1 with having the PDSCH of DL DAI=1 and not receiving PDSCH, then UE while PDSCH application space is bundled by the TDD Channel assignment of M=2 in LTE version 8 Launch ACK/NACK.When using LTE version 8TDD Channel assignment, UE launches two ACK/NACK bits.Here, can make The Channel assignment mapping relations that are used in LTE version 8 (such as, table 5 above to 7) and the Channel assignment in LTE version 10 One of mapping relations (such as, table 8 above to 11), and this can be configured by RRC and determine.

In application LTE version 8 Channel assignment, by SPS PUCCH resource (that is, the resource set configured by higher level SPS activate resource indicated by PDCCH, see table 14) determineValue.It addition, HARQ-ACK (0) be for The ACK/NACK/DTX response that SPS PDSCH launches.This is to solve the situation that wherein UE loss has the PDSCH of DAI=1 Ambiguity and launch with may determine that for SPS launch ACK/NACK response.

In this case, the TPC field of the PDCCH with DL DAI=1 can be practically used for PUCCH power and control. But, supporting that MIMO launches in the community of (or the transmitting of 2 code words), the loss of ACK/NACK bit is likely to be due to for having The space of the PDSCH of DAI=1 bundlees and occurs.

Simultaneously, it may be considered that wherein use the situation of PUCCH format 3.

If UE receives SPS PDSCH and has the PDSCH of DL DAI=1, then UE can assume that have DL The TPC field of the PDCCH of DAI=1 is used for ARI purpose.Then, UE can use PUCCH format 3 launch 2 bit ACK/ NACK (on non-MIMO community) or 3 bit ACK/NACK (on MIMO community).

In this case, because not applying ACK/NACK to bundle, it is possible to launch ACK/NACK bit, and there is no ACK/ The loss of nack message.Meanwhile, because there is not the TPC field for original TPC command purpose (because having DL DAI=1 The TPC field of PDCCH for ARI purpose), control it is possible that perform PUCCH power improperly.

In view of this situation, it is proposed that two kinds of methods below come in CA for the resource of TDD PUCCH format 3 Distribution.

First method is to reuse the resource for FDD PUCCH format 3 in CA to distribute.In this case, exist One or more TPC fields on PCell may be used for original purpose, and or many on one or more SCell Individual TPC field may be used for ARI purpose.If UE only receives PDSCH on PCell, then can use in LTE version 8 The ACK/NACK binding of definition.

Second method is to reuse the resource for TDD PUCCH format 3 when not supporting CA (that is, in non-CA) Distribution.So, the TPC field of the PDCCH with DAI=1 on PCell may be used for original purpose, and at PCell and The TPC field of the every other PDCCH on SCell may be used for ARI purpose.When UE only receives SPS PDSCH on PCell Or when there is the PDCCH of DL DAI=1, it is possible to use LTE version 8PUCCH form 1a/1b (that is, fall-back mode operation).Work as UE When receiving SPS PDSCH and there is the PDSCH of DL DAI=1 but do not receive the PDSCH with DL DAI > 1, use LTE version 8 Channel assignment.

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

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

For using the PUCCH format 3 ACK/NACK feedback in TDD, defining mode 1 and pattern 2.Pattern 1 can be propped up Hold until the ACK/NACK payload size of 20 bits.If the quantity of indicated ACK/NACK bit is more than 20, then make Bundle with space.If the quantity of the ACK/NACK bit indicated in mode 1 is less than 20, the most do not support binding.Meanwhile, mould Formula 2 is the scheme of wherein application part binding together with the binding of space (binding in the time domain or the binding in CC territory).That is, In mode 2, if the quantity of indicated ACK/NACK bit is more than x, then simultaneously perform space binding with part binding.

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

On the other hand, the resource distribution for PUCCH format 3 is defined as foloows.Corresponding with PDSCH on PCell 2 bit TPC fields in PDCCH are for the TPC command of original purpose.2 ratios of the PDCCH corresponding with PDSCH on SCell Special TPC field is for ARI purpose.If the PDCCH corresponding with PDSCH not received on SCell and receiving PDSCH on PCell, then by using PUCCH 1a/1b in the scheme defined in LTE version 8.

Hereinafter, the ACK/NACK binding method when only there is DL on PCell and receiving and resource allocation methods will be described.

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 indicated The quantity of ACK/NACK bit more than 20, then needs application space to bundle.Because uncertain feedback is only when application space bundlees Vertical ACK/NACK information, it is possible that reduce the efficiency of HARQ operation, and accordingly, it would be desirable to maximally launches single ACK/ Nack message, and do not bundle.That is, space binding to the simple application of all ACK/NACK bits is in DL throughput performance Less desirable.And, because pattern 1 is the scheme launching independent ACK/NACK feedback in the case of not having to change, so Should minimally application space binding.Accordingly, it would be desirable to perform space binding so that the quantity of ACK/NACK bit is closest to 20 But it is less than 20.

For performing the detailed of space binding when quantity when indicated ACK/NACK bit explained below is more than 20 Method.

As first method, it may be considered that the space binding of (CC one by one) in units of CC.According to first method, Ke Yi Application space binding in all DL subframes in one specific CC.In this way it is possible to run through all subframes about other CC Execution space bundlees, until wanting the quantity of the ACK/NACK bit of actual transmission less than 20.Assuming that relative to SCell more frequently Scheduling PCell, can finally application space binding on PCell.

(that is, launch for sending out for the DL in 9 DL subframes in a UL subframe when TDD is configured to 9DL:1UL The configuration of the ACK/NACK penetrated, configures the subframe 2 of 5 for example, with reference to the UL-DL of table 12) time, if the quantity of CC of configuration exceedes 2, even if then space binding is applied to all of CC, ACK/NACK payload size also above 20 bits.Therefore, configuration is worked as The quantity of CC when being 2, can bundle to all of CC application space.

When TDD configuration is not 9DL:1UL, to from logic index, there is last index (or highest index) (the N of code word that CC plays beginning, that there are two configurations_{configuredDLsubframe}+N_{CW_SF}-9) individual CC application space binding.Permissible The most backward PCell application space binding (i.e., it is possible to indexing to the logic that PCell assignment is minimum).Here, N_{configuredDLsubframe} It is the wherein quantity of the DL subframe of feeding back ACK/NACK on a CC.N_{CW_SF}It is the sum of code word, for these code words, in institute On some DL CC in a subframe feeding back ACK/NACK.I.e., it is possible to determine N as shown in equation 2_{CW_SF}。

[equation 2]

$N_{CW\_SF}=\underset{i=0}{\overset{N_{configuredCCs}-1}{\Σ}}{N}_{CW,i}$

In equation 2, N_CW,iIt is the quantity of the code word of configuration in i-th CC.

As second method, it may be considered that the space binding of (subframe one by one) in units of subframe.According to second method, can Bundle with application space on all CC in a specific DL subframe.In this way it is possible to run through about other DL subframes All CC perform space binding, until wanting the quantity of the ACK/NACK bit of actual transmission less than 20.

According to above-mentioned first or second method, the quantity of the ACK/NACK bit of binding is 18,19 or 20.According to for The quantity of CC of UE configuration, shows when the number applying first or ACK/NACK bit during second method in following table 17 Amount.

[table 17]

First method can maximally support relative to second method that the independent ACK/NACK for PCell launches, and Can be easily expressed.If the quantity of indicated ACK/NACK bit is more than 20, the most preferably, CC ground performs one by one Space binding (that is, application first method).

Embodiment 10

In embodiment 10, the detailed applications example of above-mentioned pattern 2 and pattern b is described.Pattern 2 be wherein with for making With the space binding binding of application part together of the PUCCH format 3 ACK/NACK feedback in TDD (binding in the time domain or Binding in CC territory) scheme.Pattern b is wherein in the case of the quantity at indicated ACK/NACK bit is more than 4 Application section together with bundling with the space for using PUCCH format 1b ACK/NACK in TDD to feed back during application Channel assignment Divide the scheme of binding (binding in the time domain or the binding in CC territory).

Pattern 2 can be used to improve the ACK/NACK performance of the UE about power limited valuably.Straight when supporting To the FDD of ACK/NACK of 10 bits with support until the TDD of the ACK/NACK of 20 bits makes comparisons time, TDD has than FDD more Little UL covers.It addition, when in configuring at TDD 9DL-1UL, the quantity of DL CC is more than 2, pattern 1 is (wherein, when indicated Application space binding when the quantity of ACK/NACK bit is more than 20, and when the quantity of indicated ACK/NACK bit be 20 or Not application space binding time less) can not support that ACK/NACK feeds back.Such as, in order to support on 5 DL CC and at TDD ACK/NACK feedback in 9DL-1UL configuration, needs 45 ACK/NACK bits altogether, though application space binding.Therefore, for In TDD9DL-1UL configures, at least support ACK/NACK feedback, need to support the above-mentioned pattern 2 for PUCCH format 3.

Hereinafter, will be described in the space binding that pattern 2 and pattern b are applied.

Embodiment 10-1

In embodiment 10-1, describe space binding in the time domain.In addition to space bundlees, it is also possible to perform Time domain binding in this embodiment.

Can perform as space binding time domain binding, and the most additionally revise on each CC in LTE version 8 2 bit DAI of definition.And, in application time domain binding, time domain can be applied on each CC simply to bundle, and not Various forms of CA must be considered.That is, i.e. it is enough to determine the time domain binding method of the various situations for CA.Because tying as time domain The size of the ACK/NACK information bit of the application result tied up is 10 bits, it is possible to by the PUCCH format 3 of LTE version 10 Structure is used as the PUCCH format that ACK/NACK to be used for launches.

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

Figure 40 is the figure of illustrative exemplary domain portion binding.4 subframes in the example of Figure 40, on each CC Upper application ACK/NACK bundlees.

In a CC of Figure 40, UE has been received by the PDCCH with DAI=0 in the first subframe and second The PDCCH with DAI=1 in subframe, but also it is not received by the PDCCH with DAI=2 in the 3rd subframe.So After, because UE does not knows whether to have transmitted last PDCCH (DAI=2), have been received by so UE can identify All PDCCH in time domain bundled window.It addition, Figure 40 illustrates following situation, wherein, it is successfully decoded (that is, ACK) by connecing Each of the PDSCH of the PDCCH scheduling received, and as result, produce the ACK ACK/NACK information as binding.With institute Together, UE can encode last received DAI value to the ACK information produced, i.e. 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.UE can be by last received DAI value (that is, DAI=0) encodes together with ACK information.Because UE encodes and launches ACK and DAI (DAI=0), so BS is permissible 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 3rd PDCCH (DAI=2) in subframe.Even if UE unidentified go out PDCCH (DAI=1) in the second subframe transmitting, UE is permissible Identify itself and have lost PDCCH (DAI=1), because the DAI value of the PDCCH received the most sequentially increases.Although Figure 40 shows Go out wherein to be successfully decoded (that is, ACK) situation of each by the PDSCH of the PDCCH scheduling received, but UE can The NACK ACK/NACK information as binding can be produced, because have lost the transmitting of a PDCCH.

In the 4th CC of Figure 40, UE only receives PDCCH (DAI=0), and dispatches by PDCCH being successfully decoded PDSCH time produce ACK information.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 knows in the 4th subframe Transmit the PDCCH with DAI=1.Figure 40 illustrates that the most not successfully decoding (that is, NACK) is by the PDCCH received by UE Scheduled PDSCH.Therefore, UE can produce nack message.

Therefore, when applicable during domain space binding, 2 bit TDD of LTE version 8 can be reused on each CC DAI (that is, as PDCCH stored counts device) and without amendment.

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

[table 18]

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

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

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

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

Embodiment 10-2

In embodiment 10-2, describe the binding of CC domain space.In addition to space bundlees, can perform to implement at this Time domain binding in example.

In CC territory bundlees, it is preferred that use DAI as indicating in a subframe in the binding being made up of multiple CC The designator of the sum of the PDSCH (or PDCCH of correspondence) dispatched in window rather than use DAI are as on each CC In multiple subframes, the stored counts device of the PDSCH (or PDCCH of correspondence) of scheduling is as in conventional DAI.This is because When DAI indicates the PDSCH (or PDCCH) of each subframe total, it is not necessary to provide and abandon in time for wherein UE The solution of the situation of later PDCCH.

Then, UE can work as DL for being successfully decoded in bundled window launch the quantity of produced ACK equal to Bundled window is launched during PDSCH (or PDCCH) total ACK, and otherwise, UE launches NACK and (now, is expressed as by DTX NACK)。

Hereinafter, will be described in CC territory to bundle to pattern b and the application of pattern 2.

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

In this case, generally assume that the Channel assignment of application LTE version 10 (such as, table 8 above to 11) maps to close System.

If using the ACK/NACK PUCCH resource implicitly determining (that is, index from the CCE of PDCCH and draw), then may be used First to select the PUCCH money with the PDCCH dynamic link for the scheduling on PCC (or PCell) in each subframe Source.

If only dispatching PDSCH on PCC (or PCell) in many CC configure, then can apply in LTE version 8 ACK/NACK resource maps (such as, table 5 above to 7).I.e., it is possible to the operation of the fall-back mode performed in LTE version 8.

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

Figure 41 TDD 2DL:1UL configure in, in the first subframe because PDSCH is not scheduled on PCC and It is scheduled on SCC, so determining PUCCH resource from the CCE index of the PDCCH for dispatching SCC PDSCH.In the second subframe In, PUCCH resource can be determined from the CCE index of the PDCCH for dispatching PCC PDSCH.Such PUCCH can be used to provide Source uses channel selection operations.It is, for example possible to use Channel assignment mapping relations as shown in table 8 perform ACK/NACK Launch.

In TDD 3DL:1UL configures, all subframes are only dispatched on PCC PDSCH.In such a case it is possible to such as Upper described execution fall-back mode operation.It is, for example possible to use Channel assignment mapping relations as shown in Table 6 are passed through PUCCH format 1b performs ACK/NACK and launches.

In TDD 4DL:1UL configures, because dispatching PDSCH in the first subframe on PCC and SCC, so can PUCCH resource is determined with CCE index based on the PDCCH for dispatching the PDSCH on PCC.Because PDSCH is at the second son Frame is not scheduled and is only scheduled on a community (PCC or SCC) in the third and fourth subframe, it is possible to based on The CCE index of the PDCCH of corresponding PDSCH determines PUCCH resource.In this way it is possible to PUCCH money determined by Shi Yonging Source performs channel selection operations.It is, for example possible to use the Channel assignment mapping relations shown in table 10 perform ACK/ NACK launches.

The example applying CC territory to bundle to pattern 2 is described with reference to Figure 42.

In the example of Figure 42, it is assumed that the maximum quantity of ACK/NACK bit is 12, and maximum bundled window is 2 (i.e., Most two CC are included) a bundled window.

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

It addition, do not include PCell (or PCC) in bundled window.That is, bundled window is configured only 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 ACK/NACK The quantity (quantity of the ACK/NACK bit after application space bundlees) of bit becomes 12 or less.

In the 2DL:1UL of Figure 42 configures, because the quantity of the ACK/NACK bit after performing space binding is 10, institute Not configure bundled window.

In 3DL:1UL configures, 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 to two CC (SCC3 and SCC4) is 12, and And therefore, it is not reconfigured at bundled window.

In the 4DL:1UL of Figure 42 configures, because the quantity of the ACK/NACK bit after performing space binding is 20, institute To configure bundled window.When being configured to the bundled window of two CC (SCC3 and SCC4), produce 16 bit ACK/NACK, and And therefore, configure another bundled window.If configuring another bundled window for two CC (SCC1 and SCC2), then produce 12 bit ACK/NACK, and therefore, it is not reconfigured at bundled window.

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

Embodiment 11

Embodiment 11 relates to when only receiving PDCCH/PDSCH on PCell (the most only PCell reception) and passes through The ACK/NACK launching technique of PUCCH format 3.Especially, the only PCell being described in detail in TDD receives.

When not receiving on SCell and only receive the PDCCH corresponding to PDSCH on PCell, it is possible to use The PUCCH format 1a/1b resource (i.e., it is possible to running in fall-back mode) of LTE version 8.

In fdd, can apply fall-back mode for use the PUCCH resource defined in LTE version 8 purpose and Determine the purpose of PUCCH resource clearly, even if not receiving ARI on SCell.

If TPC field is for the ARI purpose on SCell, then ACK/NACK resource may be in only PCell reception condition Lower fuzzy.In order to solve this problem, can apply at the ACK/NACK multiplexing defined in LTE version 8TDD system or ACK/NACK Binding.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 handling capacity may be produced.And, because carrying out lap ACK/NACK with ACK/NACK mapping relations State, there is no assurance that the ACK/NACK performance of 4 bit ACK/NACK in LTE version 8TDD system.

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, it is possible to use defined in LTE version 8 The resource of PUCCH format 1a/1b.In such a case it is possible to the use of DAI and ARI is 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 is used as PDCCH The stored counts device of (or PDSCH).As in LTE version 8TDD system, the DAI on SCell is used as PDCCH The stored counts device of (or PDSCH).DAI on SCell can be configured to ' 00 '.In the examples shown of Figure 43, SCell The DAI value of PDCCH be all configured to ' 00 '.If the DAI value of the PDCCH on SCell be configured identically into ' 00 ', then imperial edict can also dispatch PDCCH DCI in public search space.Realizing aspect at UE, predefined value ' 00 ' is permissible It is 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, there is the PDCCH of DAI=00) first distributed on PCell TPC command for original purpose.Every other PDCCH (bag in addition to the PDCCH with DAI=00 on PCell Include PCell and SCell) TPC field for ARI purpose, the field for ARI purpose in PDCCH should be all of PDCCH has identical value.

UE behavior in this case can be defined as foloows.

If the PDSCH that there is the PDCCH not having correspondence on PCell launches (i.e., only SPS PDSCH),

√ launches without other PDSCH,

● 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 √ exist on PCell have DAI=' 00 ' single PDSCH or on PCell exist be used for indicating DL The single PDSCH with DAI=' 00 ' of SPS release,

● use LTE version 8PUCCH form 1a/1b.

√ otherwise,

● use PUCCH format 3.

In superincumbent explanation, wherein the situation of ' PDSCH that there is the PDCCH not having correspondence launches ' is corresponding to DL SPS PDSCH.And, ' the single PDSCH ' instruction with DAI=' 00 ' is being 00 corresponding to the DAI field in the PDCCH of PDSCH.

Embodiment 11-1 is applicable to include for the 9DL:1UL sub-frame configuration of TDD ACK/NACK feedback and for pattern 1 The all situations of the time domain/CC territory binding with pattern 2.

The above embodiments 11-1 are aggregated as follows.

Use LTE version 8PUCCH form 1a/1b and the resource of PUCCH format 1a/1b in the following cases: (1) wherein PCell exists ' not having the situation of single PDSCH ' of the PDCCH of correspondence, (2) the most only exist on PCell that ' it is right to have The single PDSCH ' of the PDCCH answered and the DAI value in PDCCH are the situations of 00, or (3) the most only deposit on PCell ' the single PDCCH ' of instruction DL SPS release and DAI value in PDCCH be 00 situation.

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

' PDSCH (that is, DLSPS PDSCH) ' of the PDCCH of correspondence is not had, then under performing if do not existed on PCell The operation in face.If existed on PCell, ' the DAI value of the PDSCH ' and PDCCH with the PDCCH of correspondence is 00, then The TPC field of PDCCH is for actual TPC command.If there is ' the PDCCH ' and the DAI of PDCCH of instruction DL SPS release Value is 00, then the TPC field of PDCCH is used for actual TPC command.In other cases, all of TPC field is used as ARI.

(that is, PCell exists and ' there is no PDSCH (that is, the DL SPS of the PDCCH of correspondence in other cases PDSCH) '), all TPC fields of PDCCH are used as ARI.

It addition, in the case of on all of, 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 purpose, and the TPC field on PCell is for original TPC purpose.According to this embodiment, in TDD, by the TPC in PDCCH in the way of similar, on PCell Field is used for original TPC purpose, and the TPC field in the PDCCH on SCell is for ARI purpose.In this case, may be used With perform with the identical PUCCH power control operation of operation in tradition LTE version 8 and without revising.

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

As in the example of Figure 44, about only receiving the UE of PDSCH on PCell, the PDCCH's on PCell DAI field may be used for ARI purpose.Using such DAI field is available in mode 1, because pattern 1 need not be supported DAI in time domain/CC territory binding.It addition, be used as field (the DAI field on PCell and at SCell of the ARI of PDCCH On TPC field) should have identical value.

In the examples shown of Figure 44, the DAI value of the PDCCH on SCell is all configured to ' 00 '.Omit it to say It is bright, because it is identical with the explanation of Figure 43.

UE behavior based on description above is defined as foloows.

√ TPC field is used for TPC command.

√ DAI field is used as the ARI for PUCCH format 3.

For dispatching the PDCCH of PDSCH on SCell,

√ TPC field is used as the ARI for PUCCH format 3.

Exceptionally, only for there is no the SPS PDSCH of PDCCH,

√ uses LTE version 8PUCCH form 1a/1b (carrying out RRC configuration for SPS).

Example 9 above to 11 relate generally to for being launched by the ACK/NACK of PUCCH in a tdd system this Bright detailed applications example.

Embodiment 12

In this embodiment 12, it is described on PCell and ' PDCCH ' of instruction DL SPS release is using the side of ARI Method.

Specifically, embodiment 12 relate to a kind of for do not exist on one or more SCell PDSCH and In the case of there is SPS PDSCH (that is, not having the PDSCH of PDCCH of correspondence) on PCell, single when receive on PCell ' during the PDCCH ' of instruction DL SPS release, by reusing ' the TPC field of the PDCCH ' of instruction DL SPS release, via PUCCH format 3 launches the method for ACK/NACK.I.e., it has been described that (that is, there is not correspondence for SPS PDSCH ought not be there is The PDSCH of PDCCH) and the method for launching ACK/NACK when receiving single PDSCH on PCell.In this embodiment In, PDSCH (that is, tool is with/without the PDSCH of corresponding PDCCH) ought not be there is and on PCell, receive ' instruction in description Another kind of ACK/NACK launching technique during the PDCCH ' that DL SPS discharges.

A kind of method using ARI in fdd is as follows.

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

Otherwise, if only there is single PDCCH (i.e., the only SPS release of instruction DL SPS release on PCell PDCCH)。

√ uses PUCCH format 3.

√ is exceptionally, it is also possible to the TPC field of the PDCCH of instruction DL SPS release is used as ARI.

Otherwise,

√ uses PUCCH format 3.

It follows that the method for use DAI and ARI is as follows in TDD.

As in LTE version 8, the DAI on PCell is used as the stored counts device of PDCCH/PDSCH.For The DAI of SCell is configured to preset value (such as, ' 00 ') so that dispatch DCI on public search space.Aspect is realized at UE, This preset value is used as virtual CRC.

The TPC field of the PDCCH (that is, having the PDCCH of DAI=1 or DAI=00) first distributed on PCell is used for The TPC command of original purpose.Every other PDCCH in addition to the PDCCH first distributed on PCell is (that is, at PCell On other PDCCH and PDCCH on SCell) TPC field for ARI purpose.Other PDCCH superincumbent work as DAI TPC field when=' 00 ' is used also as ARI.It addition, UE supposes that all of ARI value is identical.

Embodiment 13

Embodiment 13 relates to a kind of according to whether there is SPS PDSCH to the method using different TPC fields.

As it has been described above, produce ACK/NACK response about three kinds of situations.Situation 1 relates to having corresponding PDCCH's PDSCH, situation 2 relates to the PDCCH indicating DL SPS release, and situation 3 relates to not having the PDSCH of PDCCH of correspondence.Situation 3 also referred to as the ACK/NACK of SPS PDSCH.

In the explanation of this embodiment, for ' PDCCH ' instruction situation 1 relevant to ACK/NACK response or situation 2, ' SPS PDSCH ' indicates situation 3, and particular UE performs to receive for the DL of three kinds of situations above and perform for DL reception The operation of ACK/NACK illustrates.In the n-th-k subframe (wherein, the ACK/NACK response launched in the n-th UL subframe has K ∈ K, and K:{k₀,k₁,…k_M-1, and see table 12) in for above three kinds of situations DL launch ACK/NACK response Relation.Hereinafter, the explanation of ACK/NACK transmitting subframe position will be omitted.

If launching ACK/NACK by various forms from UE, then increase the complexity that BS explains the blind decoding of ACK/NACK Degree.In order to improve the performance in BS, such as complicated blind decoding, and in order to be efficiently used resource, it is possible to use by relatively The PUCCH format of high-rise configuration.Hereinafter, will be described in depending on whether to there is SPS PDSCH and use different TPC fields Method.

When configuring a Serving cell, the use of (2 bit) TPC field can be defined below.When there is SPS During PDSCH, the TPC field in all of PDCCH can be used as ARI, and UE can assume that ARI value is all of In PDCCH identical.Meanwhile, if there is no SPS PDSCH, then the TPC field of the PDCCH with DL DAI=1 may be used for Original TPC command, and the TPC field with the PDCCH of DL DAI > 1 is used as ARI.UE can assume that have DL ARI value in all PDCCH of DAI > 1 is identical.

It addition, when configuring a Serving cell, the use of PUCCH format can be defined below.If UE ' is only ' connect Receive SPS PDSCH, then can use LTE version 8PUCCH form 1a/1b.Or, if UE ' is only ' receive there is DL The single PDCCH of DAI=1, then can use LTE version 8PUCCH form 1a/1b.In other cases, can be by PUCCH lattice Formula 3 is used as the PUCCH format configured by higher level.

If DL DAI is used as simple counter (PDCCH stored counts device), then the TDD PUCCH format 3 in CA Resource distribution can be identical with the resource distribution in single carrier wave (or non-CA).That is, for the resource allocation methods of PCell The method identical with the resource allocation methods in non-CA can be used.In the case of a ca, can be by for multiple communities PUCCH resource distribution is defined below.

If configuration is more than a Serving cell, then the use of TPC field can be defined below.When there is SPS During PDSCH, the TPC field of all PDCCH on PCell and one or more SCell can be used for ARI purpose, and UE can assume that at PCell identical with the ARI value on all PDCCH on one or more SCell.Meanwhile, if there is no SPS PDSCH, the most only the TPC field of the PDCCH with DL DAI=1 on PCell may be used for original TPC command, And the TPC field of the every other PDCCH on PCell and one or more SCell may be used for ARI purpose.UE is permissible Assuming that it is identical with the ARI value on all PDCCH on one or more SCell at PCell.

If configuration is more than a Serving cell, then the purposes of PUCCH format can be used as follows.If UE ' is only ' connect Receive SPS PDSCH, then can use LTE version 8PUCCH form 1a/1b.Or, if UE ' is only ' receive there is DL The single PDCCH of DAI=1, then can use LTE version 8PUCCH form 1a/1b.For other situations, can be by PUCCH lattice Formula 3 is used as the PUCCH format configured by higher level.

Embodiment 14

Embodiment 14 relates to PUCCH money in view of above-described embodiment, for TDD HARGACK/NACK response transmitting Source distribution method.

In tradition LTE version 8/9 system, because sending out to the ACK/NACK exceeding regulation bit size (such as, 4 bit) Penetrate application ACK/NACK binding (space binding and/or time domain binding), so having created the damage of independent ACK/NACK information Lose.In LTE version 10 (or LTE-A) system, design PUCCH format 3 is to support until the independent ACK/NACK of 20 bits The transmitting of information.In CA and/or TDD support system, because the situation wherein launching 20 bits or more ACK/NACK can Can occur, so needing the method for effectively utilizing resource while launching ACK/NACK information without loss.

Figure 45 is the figure of the example of the present invention illustrating the use for the TPC field in PDCCH.Example at Figure 45 In, ARI is the information of the resource indicating the PUCCH format 3 for ACK/NACK transmitting.Although there is DL on PCell The TPC field of the PDCCH of DAI=1 is for original TPC command, but the TPC word of other PDCCH on PCell and SCell Section is used as ARI.UE can assume that the ARI value on PCell with SCell is identical.Therefore, even if an ARI only being detected, also May determine that the resource of PUCCH format 3.

When TPC field is re-used as ARI, the precision that PUCCH power controls may be reduced.But, because can lead to Cross ARI information and positively determine the resource of PUCCH format 3, so relative to the fall in the precision that PUCCH power controls Low, use the transmitting not having lossy ACK/NACK information of PUCCH format 3 to be probably preferably for whole system.

In the example of Figure 45, when UE success in detection includes at least one PDCCH of ARI, it is possible to use by The PUCCH format 3 of ARI instruction launches ACK/NACK response.But, if UE ' is only ' detect there is no the PDCCH of ARI (i.e., The PDCCH with DAI=1 on PCell), then UE can not obtain ARI information, and not can determine that PUCCH format 3 resource. In such a case it is possible to use conventional form, i.e. PUCCH format 1a/1b of LTE version 8/9 is launched without information loss ACK/NACK responds.

It is, therefore, possible to provide a kind of resource allocation methods, the method can without any loss launch at one or The DL launched in multiple DL subframes launches the ACK/NACK response of (PDCCH and/or PDSCH).It addition, because with CA or non-CA without Close ground and determine PUCCH format and PUCCH resource in the same manner, it is possible to simply and clearly dictate the behaviour of BS and UE Make.

Figure 46 is the overall flow figure of various embodiments illustrating to propose in the present invention.In the example of Figure 46, logical Cross higher level for providing explanation on the premise of UE configuration PUCCH format 3.

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

If the result of step S4610 is yes, then perform step S4620.Because having DAI=1's on PCell The TPC field of PDCCH is used for original TPC command, so UE can not obtain ARI when only receiving the PDCCH with DAI=1 Information.Therefore, UE does not use PUCCH format 3.UE can use PUCCH format 1a/1b to launch ACK/NACK.Can pass through Implicit expression maps (that is, by indexing from the extractive PUCCH resource of CCE rope of PDCCH) and determines the money of PUCCH format 1a/1b Source.

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

If the result of step S4630 is yes, then perform step S4640.Because UE is also not received by PDCCH, so UE can not obtain ARI information, and does not use PUCCH format 3.UE can use PUCCH format 1a/1b to launch ACK/ NACK.Here, because be also not received by PDCCH, so UE can not draw from the PDCCH extractive PUCCH resource of CCE rope Index.Therefore, UE can be according to the information included at SPS activation PDCCH (such as, by the TPC in activating PDCCH at SPS Field reuse indicated information) determine that PUCCH resource indexes.

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

If the result of step S4650 is yes, then perform step S4660.Even if in this case, because can not obtain ARI information, so UE uses PUCCH format 1a/1b to replace PUCCH format 3.Here, UE can pass through channel selection profile Launch ACK/NACK information, in order to prevent the loss of ACK/NACK information.Channel assignment can be performed so that from A (=2 or 3) individual PUCCH resource selects PUCCH resource.Here, can determine A's according to the quantity of the code word (or transmission block) of PDSCH Value.

Meanwhile, if the result of step S4650 is no, then perform step S4670.In step S4670, UE may determine that Wherein DAI value is not whether the value of ARI (that is, TPC field) of PDCCH of 1 (that is, DAI > 1) is equal at one or more SCell On ARI (that is, the TPC field) value of all PDCCH.

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

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

In a word, it should be launched ' having the PDSCH ' of PDCCH, ' do not have the PDSCH of PDCCH of ACK/NACK for UE ' and ' SPS discharges PDCCH ', can define following UE behavior (SPS-PDSCH).But, the scope of the present invention is not limited to this, And can be distributed by the available set incompatible execution TDD HARQ ACK/NACK resource of various embodiments of the present invention and launch Operation.

First, the operation of non-CA system can operate identical with ' the only PCell reception ' in CA environment.That is, when for UE configure a Serving cell time TDD HARQ ACK/NACK resource distribution and launch operation can with when in configuration more than one TDD HARQ ACK/NACK resource when only receiving PDSCH and/or PDCCH in the case of individual Serving cell on PCell is divided Join identical with launching operation.Therefore, below, when configuring only one Serving cell, can be by the description of the operation on PCell Replace with operation on the serving cell.

If the DAI in the PCell PDCCH corresponding to PDSCH is 1, then TPC field controls mesh for original power 's.If being more than 1 corresponding to the DAI in the PDCCH of PDSCH, then TPC field is used as ARI.Corresponding on SCell TPC field in the PDCCH of all PDSCH is used as ARI.UE supposes that all of ARI value is identical.

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

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

If only receiving a PDSCH and a SPS-PDSCH with DAI=1 on PCell, then by using The channel selection profile of PUCCH format 1b performs ACK/NACK and launches.Quantity A for the PUCCH resource of Channel assignment is 2 Or 3.

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

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

Therefore, for only at PCell or receive on PCell and one or more SCell and ' have PDCCH's The all situations of one of PDSCH ', the PDSCH (SPS-PDSCH) ' of PDCCH ' do not have and ' SPS release PDCCH ', can not damage ACK/NACK information correctly and is effectively launched in the case of losing ACK/NACK information.
