Fig. 2 be shown in UE and BS each in transmitter exemplary structure.It is retouched in more detail below with reference to Fig. 2 State the operation of transmitter 100a and 100b.

Referring to fig. 2, each of transmitter 100a and 100b includes scrambler 301, modulation mapper 302, layer mapper 303, precoder 304, resource element (RE) mapper 305 and orthogonal frequency division multiplexing (OFDM) signal generator 306.

Transmitter 100a and 100b can emit more than one code word.The encoding ratio of each code word of the scrambling of scrambler 301 Spy, for emitting on the physical channel.Code word can be referred to as data flow, and be equal to the data block provided from MAC layer.From The data block that MAC layer provides is referred to as transmission block.

Scrambled bit modulation is complex-value modulation symbol by modulation mapper 302.Modulation mapper 302 can be according to pre- Scrambler bits are modulated to represent the complex-value modulation symbol of the position on signal constellation (in digital modulation) by modulation scheme.Modulation scheme not by Limitation, and m phase-shift keying (PSK) (m-PSK) and m quadrature amplitude modulation (m-QAM) can be used for the data of modulating-coding.

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

Layer mapper 303 can be with complex modulation symbols of the precoding on each layer, to be emitted by antenna port.More Specifically, precoder 304 is used for multiple transmitting antenna 500-1 to 500-N by handling with MIMO scheme_tComplex-value modulation Symbol distributes the antenna special symbol to RE mapper 305 to generate antenna special symbol.That is, precoder 304 will be sent out It penetrates layer and is mapped to antenna port.Precoder 304 can be by the output x of layer mapper 303 multiplied by N_t×M_tPre-coding matrix W, and And with N_t×M_FThe form of matrix z exports resulting product.

RE mapper 305 maps the complex-value modulation symbol for being used for corresponding antenna port/it is assigned to RE.RE mapper 305 can to subcarrier appropriate distribute be used for corresponding antenna port complex-value modulation symbol, and can according to UE come It is multiplexed them.

Ofdm signal generator 306 is modulated by OFDM or single carrier frequency division multiplexing (SC-FDM) for corresponding antenna The complex-value modulation symbol of port, that is, thus antenna special symbol generates complex values time domain OFDM or SC-FDM mark signal. Ofdm signal generator 306 can execute inverse Fast Fourier Transform (IFFT) antenna special symbol, and produce to result Cyclic prefix (CP) is inserted into raw IFFT time-domain symbol.OFDM symbol passes through transmitting after digital-to-analogue conversion, frequency upooaversion etc. Antenna 500-1 to 500-N_tIt is launched into receiver.Ofdm signal generator 306 may include IFFT module, CP inserter, number Mode converter (DAC), Frequency up-converter etc..

Meanwhile if transmitter 100a and 100b are used for the transmitting of code word, transmitter 100a and 100b using SC-FDMA It may include discrete Fourier (DFT) module 307 (or Fast Fourier Transform (FFT) module).DFT block is specific for antenna Semiology analysis DFT or FFT, and DFT/FFT symbol is exported to RE mapper 305.SC-FDMA is for by reducing signal Peak-to-average power ratio (PAPR) or cubic metric (CM) and the launch scenario for emitting signal.It, can be with obstructed overpower according to SC-FDMA Amplifier nonlinearity distortion zone and emit signal.Therefore, even if when transmitter is than the power in conventional OFDM scheme When low power transmission signal, receiver can also receive the signal for meeting constant intensity or error rate.That is, SC- can be passed through FDMA reduces the power consumption of transmitter.

In conventional ofdm signal generator, the signal carried on each carrier wave is while passing through IFFT by overloading Wave modulation (MCM) emits simultaneously concurrently with each other, thus reduces the efficiency of power amplifier.On the other hand, in SC-FDMA, Information carries out DFT/FFT before signal is mapped to subcarrier.By the signal of DFT block 307 by DFT/FFT effect Increase PAPR.The signal of DFT/FFT processing is mapped to subcarrier, is handled by IFFT, and be converted into time-domain signal. That is, SC-FDMA transmitter executes DFT or FFT operation in taking a step forward for ofdm signal generator, so that the PAPR of transmitting 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 increase before existing ofdm signal generator DFT block (or FFT Module) 307.

SC-FDMA should meet single carrier property.Fig. 3 is shown in while meeting single carrier property in a frequency domain to sub- load The example of wave mapping input symbol.If DFT symbol is assigned to son according to one of scheme shown in Fig. 3 (a) and 3 (b) Carrier wave can then obtain the transmitting signal for meeting single carrier property.Fig. 3 (a) illustrates centralized mapping, and Fig. 3 (b) diagram point Cloth mapping.

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

Fig. 4 diagram is for grasping the signal processing that the output sampling of DFT processing is mapped to single carrier in sub-clustering SC-FDMA Make.Figures 5 and 6 are shown in the signal processing operations that the output sampling of DFT processing is mapped to multicarrier in sub-clustering SC-FDMA.Fig. 4 The application of sub-clustering SC-FDMA in carrier wave is illustrated, and Figures 5 and 6 illustrate the application of intercarrier sub-clustering SC-FDMA.Fig. 5 is shown in following In the case of generated by the signal of single IFFT block: continuously distributed in the case of component carrier in a frequency domain and be aligned in continuous point Subcarrier spacing between quantum carrier wave.Fig. 6 diagram is discontinuously distributed in the case of component carrier by multiple in a frequency domain The signal of IFFT block generates.

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

Because the quantity of DFT block is equal to the quantity of IFFT block and therefore DFT block and IFFT block correspond, point Section SC-FDMA is the simple expansion of the DFT extension and IFFT subcarrier maps structure of conventional SC-FDMA, and can be expressed For NxSC-FDMA or NxDFT-s-OFDMA.In the disclosure, segmentation SC-FDMA includes all these projects.Referring to Fig. 7, Segmentation SC-FDMA in, all modulation symbols in the time domain be divided into N group (wherein, N be greater than 1 integer), and with Group is that unit carries out DFT processing, to release single carrier property constraint.

Meanwhile if receiver 300a and 300b receive the signal emitted by SC-FDMA described with reference to Fig. 3 to 7, Then each of receiver 300a and 300b further comprises IFFT module.IDFT/IFFT module I DFT/IFFT processing is solved by RE The antenna special symbol that mapper restores, and IDT/IFFT symbol is exported to multiplexer.

Although each for having described transmitter 100a and 100b in Fig. 1 to 7 includes scrambler 301, modulates and reflect 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 transmitter 100a and 100b.Equally, although in Fig. 1 It include signal restorer, multiplexer and channel demodulator to each for describing receiver 300a and 300b in 7, but can be with Further consider by signal restorer, multiplexer and channel demodulator cover receiver 300a and 300b processor 400a and In each of 400b.For convenience of description, following explanation: scrambler 301, modulation mapper is provided under the premise of following 302, layer mapper 303, precoder 304, RE mapper 305 and ofdm signal generator 306 are (in the feelings of SC-FDMA scheme Further comprise DFT block 307 under condition) be included in be configured to control its operation processor 400a and 400b separate In transmitter 100a and 100b, also, signal restorer, multiplexer and channel demodulator are included in and are configured to and control its behaviour In the receiver 300a and 300b of processor 400a and the 400b separation of work.However, even if scrambler 301, modulation mapper 302, layer mapper 303, precoder 304, RE mapper 305 and ofdm signal generator 306 (and 307) are included in processing In device 400a and 400b, and signal restorer, multiplexer and channel demodulator are (in the case where SC-FDMA scheme, further Including IFFT module) it is included in processor 400a and 400b, the embodiment of the present invention can be also applied in an identical manner.

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

Referring to Fig. 8, in 3GPP LTE/LTE-A, radio frame has the length of 10ms (307200Ts), including 10 The subframe of equal sizes.It can be by 10 subframe numbers of radio frame.Here, T_sIt is the sampling time, is expressed as T_s=1/ (2048x15kHz).Each subframe is 1ms long, including two time slots.It can be 20 of from 0 to 19 sequentially number radio frame Time slot.Each time slot has the length of 0.5ms.Time needed for emitting a subframe is defined as transmission time interval (TTI).Can be numbered by radio frame (or radio frame index), subframe number (or subframe index) or time-gap number (or Time slot index) carry out recognition time resource.

Different radio frames can be configured according to dual-mode.For example, in fdd mode because by frequency come Downlink emission and uplink transmitting are distinguished, so radio frame includes downlink subframe or uplink subframe.

On the other hand, in tdd mode, because distinguishing downlink emission and uplink transmitting, institute by the time Downlink subframe and uplink subframe are divided into the subframe in frame, and table 1 is shown in exemplary in tdd mode Line link-downlink configuration.

[table 1]

In table 1, D indicates downlink subframe, and U indicates uplink subframe, and S indicates special subframe.Special son Frame includes three down link pilot timeslot (DwPTS), protective time slot (GP), uplink pilot time slot (UpPTS) fields. DwPTS is the time slot for being preserved for downlink emission, and UpPTS is the time slot for being preserved for uplink transmitting.

Exemplary downlink/uplink (DL/UL) structure of time slot of Fig. 9 diagram in a wireless communication system.Specifically Say that Fig. 9 illustrates the structure of the resource grid of 3GPP LTE/LTE-A system in ground.There are a resource networks for each antenna port Lattice.

Referring to Fig. 9, time slot includes multiple orthogonal frequency division multiplexing (OFDM) symbol in the time domain, and in a frequency domain includes more A resource block (RB).OFDM symbol can indicate 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 Changed with depending on channel width and cyclic prefix (CP) length.For example, next time slot includes 7 the normal CP the case where OFDM symbol, and next time slot includes 6 OFDM symbols the case where extending CP.Although for illustrative purpose in Fig. 8 It is middle that subframe is shown as the time slot with 7 OFDM symbols, but the embodiment of the present invention is also applied for having any other The subframe of the OFDM symbol of quantity.Including an OFDM symbol multiplied by the resource of a subcarrier be referred to as resource element (RE) or Single-tone (tone).

It, can be by including N referring to Fig. 9^DL/UL _RBN^RB _scA subcarrier and N^DL/UL _symbThe money of a OFDM or SC-FDM symbol Source grid describes the signal emitted in each time slot.N^DL _RBIndicate the quantity of the RB in DL time slot, and N^UL _RBIt indicates The quantity of 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 It in a frequency domain include N^DL/UL _RBN^RB _scA subcarrier.The quantity of the subcarrier in a carrier wave is determined according to FFT magnitude.Son The type of carrier wave can be divided into the data subcarrier for data transmitting, for the RS subcarrier of RS transmitting and for protecting The null subcarrier of band and DC component.Null subcarrier for DC component keeps being not used simultaneously during generating ofdm signal And it is mapped to carrier frequency f₀.The carrier frequency is also referred to as centre frequency.N^DL _symbIndicate OFDM in DL time slot or The quantity of SC-FDMA symbol, N^UL _symbIndicate the quantity of the OFDM or SC-FDMA symbol in UL time slot, and N^RB _scIndicate structure At 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 _symbA continuous OFDM symbol or SC- FDMA symbol is multiplied by N in a frequency domain^RB _scA continuous subcarrier.Therefore, a PRB includes N^DL/UL _symb×N^RB _scA RE.

Each RE in resource grid can uniquely identify (k, l) by the index in time slot.K be range from 0 to N^DL/UL _RB×N^RB _sc- 1 frequency domain index, and l is range from 0 to N^DL/UL _symb- 1 when Domain Index.

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

Referring to Figure 10, each subframe can be divided into control area and data area.Control area includes from first One or more OFDM symbols that OFDM symbol starts.The control zone in subframe can be independently disposed in each subframe The quantity of OFDM symbol used in domain.Emitted by Physical Control Format Indicator Channel (PCFICH) about OFDM symbol The information of quantity.BS can emit various control information to one or more UE by control area.Control information is emitted, Physical downlink control channel (PDCCH), PCFICH and physics can be distributed to control area to mix arq and refer to Show channel (PHICH).

BS emits and the paging channel (PCH) and downlink chain as transmission channel on PDCCH to each UE or UE group It shares the associated information of resource allocation of channel (DL-SCH), UL scheduling grant, mix arq (HARQ) letter in road Breath, downlink allocation index (DAI) etc..

BS can emit the data for UE or UE group by data area.By data area emit data also by Referred to as user data.Transmitting for user data can distribute physical down link sharing channel to data area (PDSCH).Emit PCH and DL-SCH by PDSCH.UE can be read by decoding the control information emitted via PDCCH Take the data emitted by PDSCH.Emitted by PDCCH and is used to indicate which UE or UE group is PDSCH data be launched into Information and it is used to indicate how UE or UE group should receive the decode the information of PDSCH data.For example it is assumed that using radio Network Temporary Identifier (RNTI) ' A ' carrys out CRC and shelters specific PDCCH, and is emitted by specific sub-frame about using radio Resource ' B ' (for example, frequency location) and use transport format information ' C ' are (for example, transmitting block size, modulation scheme, encoded information Deng) transmitting data information.Then, UE in the cell monitors PDCCH using its RNTI information.With RNTI ' A's ' UE receives PDCCH, and the PDSCH indicated by ' B ' and ' C ' is received by the information of received PDCCH.

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

DCI format can be independently applied for each UE, and can be multiplexed multiple UE's in a subframe PDCCH.The PDCCH of each UE can be made it possible to PDCCH by independently channel coding plus cyclic redundancy check (CRC).CRC is sheltered using the unique identifier of each UE, each UE is enabled to receive its PDCCH.However, because Do not know the position that its PDCCH is launched into substantially for UE, it requires UE for the corresponding DCI in each subframe All PDCCH of format execute blind Detecting (also referred to as blind decoding), until receiving the PDCCH with its identifier.

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

Referring to Figure 11, UL subframe can be divided into control area and data area in a frequency domain.It can be to control area One or more physical uplink control channels (PUCCH) are distributed to carry uplink control information (UCI).It can be to number One or more physical uplink shared channels (PUSCH) are distributed according to region to carry user data.If UE uses SC- FDMA scheme emits for uplink, then cannot emit PUCCH and PUSCH, simultaneously 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, PUCCH format can be defined as follows.

[table 2]

In the UL sub-frame, the subcarrier far from direct current (DC) subcarrier is used as control area.In other words, it is located at UL to send out The subcarrier for penetrating the both ends of bandwidth is assigned to UL control information transmitting.DC subcarrier is retained to be emitted without being used in signal In, and carrier frequency f is mapped in the processing of the frequency upooaversion as caused by OFDM/SC-FDMA signal generator 306₀。

The PUCCH of UE is used for distribution to the RB in subframe.RB couples of RB occupies different sons in two time slots and carries Wave.This is referred to as more than RB pairs of the frequency hopping that boundary of time slot is distributed to PUCCH.However, RB is to occupancy if not using frequency hopping Identical subcarrier.Unrelated with frequency hopping, the PUCCH for a UE is assigned to one RB pairs in a subframe, and because This, in a UL subframe, identical PUCCH is emitted in each time slot by a RB once, in total twice.

Hereinafter, the RB of each PUCCH transmitting for a subframe is to the referred to as region PUCCH or PUCCH resource.Separately Outside, for convenience of description, the PUCCH for carrying acknowledgement/non-acknowledgement (ACK/NACK) is referred to as ACK/NACK PUCCH.It holds The PUCCH for carrying channel quality indicator (CQI)/precoding matrix indicators (PMI)/rank information (RI) is referred to as channel status letter (CSI) PUCCH is ceased, and the PUCCH for carrying scheduling request (SR) is referred to as SR PUCCH.

The PUCCH resource emitted from BS to UE assignment for UCI according to explicit or implicit scheme.

UCI, ACK/NACK, CQI, PMI, RI, SR etc. can be emitted 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 emits number to UE/BS According to then UE/BS decodes received data.If being successfully decoded data, emit ACK to BS/UE.If data decoding is lost It loses, then emits NACK to BS/UE.In 3GPP LTE system, UE receives data cell (for example, PDSCH) from BS, and passes through By carry implicit PUCCH resource determined by the PDCCH resource for the scheduling information of the data cell come to BS transmitting for The ACK/NACK of the data cell.

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

In LTE system, the PUCCH resource of ACK/NACK is not used for each UE distribution in advance, and is located at cell In multiple UE each time point in a manner of dividing use multiple PUCCH resources.Specifically, based on carrying PDSCH Scheduling information PDCCH come implicitly determine for UE ACK/NACK transmitting PUCCH resource, the PDSCH carrying correspond to DL data.Wherein emitting the whole region of PDCCH in DL subframe includes multiple control channel elements (CCE), also, to UE The PDCCH of transmitting includes one or more CCE.Each CCE includes multiple resource element groups (REG) (for example, 9 REG).When When excluding reference signal (RS), a REG is made of four continuous RE.UE emits ACK/ by implicit PUCCH resource NACK, the implicit PUCCH resource are used in specific CCE index in the index constituted by the CCE of the received PDCCH of UE What the function of (for example, first or minimum CCE index) was exported or calculated.

Referring to Figure 12, each PUCCH resource index corresponds to the PUCCH resource for ACK/NACK.Such as institute in Figure 12 Show, it is assumed that PDSCH scheduling information is emitted to UE by the PDCCH that is made of the CCE of number 4 to 6, then UE is by from CCE Number 4, the i.e. minimum CCE of PDCCH, export or the PUCCH calculated, for example, emitting ACK/ to BS by PUCCH number 4 NACK.Figure 12 shows an example, wherein exists in DL subframe up to M' CCE, and exists in the UL sub-frame until M A PUCCH resource.Although M' can be equal to M, M' can be different from M, and can come in an overlapping manner mapping CCE with PUCCH resource.

For example, it is as follows PUCCH resource can be indexed determination.

[equation 1]

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

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

Referring to Figure 13, a UL of the general FDD wireless communication system by a DL band and corresponding to the DL band is brought Transmitting and reception data.The data and/or control information that BS and UE transmitting and reception are dispatched as unit of subframe.By in UL/ The data area configured in DL subframe emits and receives data, and the control area by being configured in UL/DL subframe come Transmitting and reception control information.For this purpose, UL/DL subframe carries signal on various physical channels.Although being based on FDD for convenience Scheme provides the explanation of Figure 13, but explanation 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 exemplary communication under multi-carrier case.

Lte-a system is polymerize using carrier wave or aggregated bandwidth, and carrier wave polymerization or aggregated bandwidth are by polymerizeing multiple UL/DL frequencies Rate block is to use broader UL/DL bandwidth using broader frequency band.Multicarrier system or carrier wave polymerization (CA) system refer to It is to polymerize each there is system of the multiple carrier waves of the bandwidth more narrower than target bandwidth to support for broadband.When polymerization has When multiple carrier waves of the bandwidth more narrower than target bandwidth, the bandwidth for polymerizeing carrier wave can be limited to the band used in conventional systems Width, to keep the backward compatibility with legacy system.For example, LTE system can support the band of 1.4,3,5,10,15 and 20MHz Width, and the bandwidth supported in LTE system can be used to support ratio from advanced LTE (LTE-A) system that LTE system improves The broader bandwidth of 20MHz.Furthermore it is possible to new bandwidth is defined to support CA, and it is 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 It examines, when only one component carrier (CC) is used for the communication in TDD, this corresponds in the single carrier case (non-CA) of Figure 13 Communication.UL CC and DL CC are also known respectively as UL resource and DL resource.

For example, with reference to Figure 14, it is 5 CC of 20MHz to support that each of which can be polymerize in each of UL and DL The bandwidth of 100MHz.Corresponding CC can be continuous or discontinuous in a frequency domain.For convenience, Figure 14 shows wherein UL The situation that the bandwidth of CC is identical as the bandwidth of DL CC and the two is symmetrical.However, it is possible to independently determine the band of each CC It is wide.For example, can be with 5MHz (UL CC0)+20MHz (UL CC1)+20MHz (UL CC2)+20MHz (UL CC3)+5MHz (UL CC4 mode) configures the bandwidth of UL CC.Also asymmetric CA can be configured, wherein the quantity of UL CC and the quantity of DL CC It is different.Asymmetric CA can due to available band limitation and be generated, or can be formed intentionally by network configuration.Example Such as, even if Y (≤X) a DL CC can be restricted to by the received frequency band of particular UE when BS manages X DL CC.? In this case, UE needs to monitor DL signal/data by Y CC transmitting.In addition, even if when BS manage L UL CC when, energy It is enough that M (≤L) a UL CC can be limited to by the received frequency band of particular UE.Confined DL CC or UL CC quilt for particular UE Service UL or the DL CC referred to as configured in particular UE.BS can by activate by BS CC manage some or all or lead to Disabling is crossed by some CC that BS is managed come to the CC of UE distribution provisions quantity.BS can change activation/disabling CC, and change The quantity of activation/disabling CC.Meanwhile BS can be with cell specifically or UE specifically configures UE should monitor/received Z first A DL CC (wherein, 1≤Z≤Y≤X) is used as main DL CC.Moreover, BS can with cell specifically or UE specifically configure UE should Monitoring/received N number of UL CC (wherein, 1≤N≤M≤L) is used as main UL CC first.In this way, for the limit of particular UE The main DL or UL CC of system is also referred to as service UL or the DL CC configured in particular UE.Can it is specific with cell, UE group is specific Ground or UE are specifically configured to the various parameters of CA.

Once BS cell is specifically or UE specifically can use CC to UE distribution, then at least the one of distributed CC is not disabled It is a, except non-reconfigurable is switched to the whole CC of UE distribution or UE.Hereinafter, except non-reconfigurable is no to the whole CC of UE distribution The CC not disabled then is referred to as main CC (PCC), and BS is free to activation/disabling CC and is referred to as auxiliary CC (SCC).It is single Carrier communication is used to communicate using a PCC for the communication between UE and BS, and without using SCC.It is also possible to PCC and SCC are distinguished based on control information.For example, specific control information can be set as only emitting/connecing by specific CC It receives.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 Such as, such specific control information can correspond to by the control information that PUCCH emits.Therefore, if emitted on PUCCH Control information BS only can be emitted to from UE by PCC, then the UL CC that wherein there is the PUCCH of 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 used The specific CC of UE, then the particular UE can receive the DL synchronization signal (SS) as specific control information from BS.In this case, The particular UE using come by receive DL SS establish the initial DL time synchronization DL CC (that is, for attempting to access BS's The DL CC of network) 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 using a PCC and does not use each UE SCC uses one or more SCC.However, this is the definition according to LTE-A, and each UE can be allowed to make in future With the communication of multiple PCC.PCC can be referred to as main CC, anchoring CC or main carrier, and SCC can be referred to as auxiliary CC or auxiliary Help carrier wave.

LTE-A manages radio resource using the concept of cell.Cell is defined as the combination of DL resource and UL resource, That is, the combination of DL CC and UL CC.Here, UL resource is not indispensable component.However, this is in current LTE-A standard In be defined, and in future, can permit and UL resource is used alone to configure cell.Therefore, it can be used alone DL resource Or cell is configured using both DL resource and UL resource.When supporting CA, can be indicated by system information in DL resource Association between the carrier frequency of the carrier frequency and UL resource (or UL CC) of (or DL CC).For example, can be believed by system Block type 2 (SIB2) is ceased to indicate the combination of DL resource and UL resource.Here, in carrier frequency instruction each cell or CC Frequency of heart.The cell run on basic frequency (or PCC) can be referred to as main plot (PCell), and quenching frequency (or SCC the one or more cells run on) can be referred to as one or more supplementary cells (one or more SCell).Dominant frequency Rate (or PCC) refers to executing the frequency (or CC) that initial connection is established or connects the process that re-establishes for UE.PCell can be with Refer to the cell indicated during the switching process.Quenching frequency (or SCC) refers to match after executing RRC connection and establishing The frequency (or CC) set, and can be used for providing other radio resource.PCell and SCell may be collectively termed as servicing small Area.Therefore, it is not configured CA or UE not supporting CA, being in RRC_CONNECTED (RRC connection) state, there is only A serving cell being only made of PCell.Meanwhile CA, UE in RRC_CONNECTED state are configured with to it, There may be one or more serving cells, and all serving cells may include a PCell and one or more SCell.However, can permit serving cell will include multiple PCell in future.For CA, in addition in starting initial safe activation In connection establishment process after process except the PCell of initial configuration, network can also for support CA UE configure one or Multiple SCell.However, even if UE supports CA, network that can also only configure PCell for UE, without increasing SCell.PCell can To be referred to as main CC, anchoring CC or main carrier, and SCell can be referred to as auxiliary CC or subcarrier.

In multi-carrier systems, BS can emit in given one or more cells (or one or more CC) to UE Multiple data cells, and UE can emit the ack/nack signal for multiple data cells in a subframe.UE can be with One or more cell (or DL CC) is assigned for receiving the PDSCH for being used for DL data receiver.RRC signaling can be passed through To be semi-statically configured or reconfigure the cell (or one or more DL CC) for UE.Furthermore, it is possible to pass through L1/L2 (matchmaker Body access control (MAC)) control signaling dynamically activates/disables the cell (or one or more DL CC) for UE.Cause This, will be changed by the maximum quantity of the UE ACK/NACK bit emitted according to the cell (or DL CC) that can be used for UE.That is, wanting It is configured/is reconfigured by RRC by the maximum quantity of the ACK/NACK bit of UE transmitting, or by L1/L2 signaling with sharp DL CC living (or one or more serving cells of configuration) and change.

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

Referring to Figure 15 and Figure 16, a MAC layer management one or more frequency carrier is to execute transmitting and reception.Because It is needed not be continuously by the frequency carrier of a MAC layer management, so more flexible resource management is possible.In Figure 15 and 16 In, for convenience, a physical layer (PHY) indicates a CC.Here, a PHY does not necessarily mean that independent radio frequency (RF) device. In general, an independent RF device indicates a PHY, but not limited to this.One RF device may include several PHY.

Figure 17 describes the concept that multiple MAC layers in BS manage multiple carrier waves, and Figure 18 describe it is multiple in UE MAC layer manages the concept of multiple carrier waves.Figure 19 describes another concept that multiple MAC layers in BS manage multiple carrier waves, and And Figure 20 describes another concept that multiple MAC layers in UE manage multiple carrier waves.

Other than structure as shown in figures 15 and 16, multiple MAC layers rather than a MAC layer can control multiple CC, as shown in Figure 17 to 20.

As shown in FIG. 17 and 18, each MAC layer can be with one-to-one 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 one-to-one correspondence Layer can be about other carrier Control one or more carrier waves.

System suitable for explanation above is system of one carrier wave of support to the more a carrier waves of N, and carrier wave can be Continuous or discontinuous carrier wave, and it is unrelated with UL/DL.TDD system is configured as managing N number of carrier wave, each carrier wave includes DL Emit with UL, and FDD system is configured as in UL and DL using multiple carrier waves respectively.FDD system can support asymmetry CA, wherein the quantity of the polymerization carrier wave in UL and DL and/or the bandwidth of carrier wave are different.

If the quantity for the CC polymerizeing in UL is equal to the quantity for the CC polymerizeing in DL, CC can be configured and to own CC it is compatible with the CC used in conventional systems.However, not supporting the CC of compatibility from present invention exclusion.

For convenience of description, although when emitting PDCCH on DL CC#0, transmitting corresponds to PDCCH on DL CC#0 PDSCH hypothesis under provide explanation, but it is clear that can using cross carrier wave dispatch so that in the DL different from DL CC#0 Emit PDSCH on CC.

Time slot level structure of the diagram of Figure 21 and 22 for the PUCCH format 1a and 1b of ACK/NACK transmitting.

Figure 21 be shown in normal CP in the case where PUCCH format 1a and 1b, and Figure 22 be shown in extension CP the case where Under PUCCH format 1a and 1b.Repeat identical control letter 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 generated by computer and It is orthogonal to cover (OC) or the orthogonal different resource for covering coding decoder (OCCc) (time domain extended coding decoder) to emit Ack/nack signal.OC includes such as Walsh/DFT orthogonal code.It, can be with if the quantity of CS is that the quantity of 6 and OC is 3 18 UE in total are multiplexed in same Physical Resource Block (PRB) based on individual antenna.Any time domain (FFT modulation after) or Orthogonal sequence w0, w1, w2 and w3 are applied in any frequency domain (before FFT modulation).PUCCH format 1 and PUCCH for SR transmitting Format 1a and 1b is identical in time slot level structure, and different in modulation scheme.

The PUCCH resource being made of CS, OC and PRB can be distributed to UE by radio resource control (RRC) signaling, To emit for SR and be fed back for the ACK/NACK for semi-persistent scheduling (SPS).As described with reference to Fig. 12, for dynamic ACK/NACK (or ACK/NACK for impermanent scheduling) feedback is anti-for the ACK/NACK of the PDCCH of instruction SPS release The minimum CCE index of PDCCH corresponding with PDSCH or PDCCH for SPS release can be used implicitly to divide to UE in feedback With PUCCH resource.

Figure 23 is shown in the scene for emitting UCI in the wireless communication system for supporting CA.For convenience of description, in this example In it is assumed that UCI is ACK/NACK (A/N).However, UCI may include control information, such as CSI (for example, CQI, PMI and RI) With scheduling request information (for example, SR), without limit.

Figure 23 illustrative exemplary asymmetry CA, wherein 5 DL CC are linked to single UL CC.It can be from the view of transmitting UCI Point setting asymmetry CA.That is, the DL CC-UL CC association for UCI can be set to and the DL CC-UL for data CC association is different.For convenience, if it is assumed that each DL CC can be carried up to two code words, and be used for each CC ACK/NACK quantity depend on each CC set by code word maximum quantity (for example, if BS sets specific CC It sets until two code words are arranged to the ACK/NACK of the CC even if a code word is used only in specific PDCCH on the CC 2, the i.e. maximum quantity of the code word on the CC), then at least two UL ACK/NACK bits are needed for each DL CC.? In this case, at least ten ACK/NACK bit is needed to emit on single UL CC for the received number on 5 DL CC According to ACK/NACK.If also indicating that discontinuous transmitting (DTX) state for each DL CC, at least 12 bits are needed (=5⁶=3125=11.61 bit) emit to be used for ACK/NACK.Because can get in conventional PUCCH format 1a and 1b straight To two ACK/NACK bits, so the structure cannot emit increased ACK/NACK information.Although CA, which is given, increases UCI Quantity cause example, but the situation be also likely to be due to the quantitative increase of antenna and TDD system and in After the backhaul subframe in system presence and occur.Similar to ACK/NACK emit, when on single UL CC transmitting with it is multiple When the relevant control information of DL CC, the amount for the control information to be emitted also increases.For example, CQI/ relevant to multiple DL CC The transmitting of PMI/RI information can increase UCI payload.

In Figure 23, UL anchoring CC (the also referred to as main CC of UL PCC or UL) is the CC for emitting PUCCH or UCI on it, and And can by cell specifically/UE specifically determines.In addition, DTX state can explicitly be fed back, or can be made by feedback It obtains and shares identical state with NACK.

Hereinafter, reference attached drawing to be proposed to the method for being used to effectively emit increased UCI.It is used for specifically, proposing Emit new PUCCH format/signal processing operations/resource allocation methods of increased UCI.By proposed by the present invention new PUCCH format is referred to as CA PUCCH format or the PUCCH relative to the PUCCH format 2 defined in traditional LTE version 8/9 Format 3.The technical characteristic of the PUCCH format proposed can be easily applied to can in the same manner or in a similar manner Transmit any physical channel (for example, PUSCH) of UCI.For example, the embodiment of the present invention is suitable for emission control information periodically Period PUSCH structure or aperiodic ground emission control information aperiodic PUSCH structure.

Following situations will be focused on and describe drawings and examples of the invention: using the PUCCH format 1/1a/ of tradition LTE The UCI/RS symbolic construction of 1b (normal CP) is as the subframe applied to PUCCH format 3/timeslot-level UCI/RS symbolic construction. However, for convenience, illustratively defining subframe/timeslot-level UCI/RS symbolic construction of PUCCH format 3, and the present invention It is not limited to such specific structure.It can be designed according to system and freely change UCI/RS symbol in PUCCH format 3 of the invention Number quantity and position.It is, for example, possible to use the R/S symbol structures of the PUCCH format 2/2a/2b of traditional LTE to define according to this The PUCCH format 3 of one embodiment of invention.

The PUCCH format 3 of embodiment according to the present invention can be used for emitting the UCI of any type or size.For example, can To emit the information of such as HARQ ACK/NACK, CQI, PMI, RI and SR with the PUCCH format 3 of embodiment according to the present invention. The information can have the payload of any size.For convenience of description, explanation below is focused on according to the present invention The transmitting of the ACK/NACK information of PUCCH format 3.

Figure 24 to 27 illustrates the PUCCH format structure and its signal processing operations for feeding back multiple ACK/NACK bits. For example, PUCCH format can be used when feeding back multiple ACK/NACK bits in multicarrier environment.Such PUCCH format PUCCH format 3 can be referred to as, the conventional inline of itself and PUCCH format 1 and 2 is distinguished.

Figure 24 to 27 illustrates the PUCCH format structure based on DFT.According to the PUCCH structure based on DFT, PUCCH is by DFT Precoding, and time domain OC is applied to it at SC-FDMA grades before transmission.Hereinafter, the PUCCH format based on DFT is referred to as PUCCH format 3.

Figure 24 diagram uses the exemplary structure of the PUCCH format 3 of the OC of spreading factor (SF) 4 (SF=4).Referring to figure 24, channel coding blocks to information bit a_0, a_1 ..., a_M-1 (for example, multiple ACK/NACK bits) channel coding, and Generation 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 It is small.The information bit includes UCI, such as multiple ACK/ of multiple data (or PDSCH) received 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.For example, if information bit includes multiple ACK/NACK for multiple DL CC, for entire bit information Channel coding is executed, rather than channel coding is executed for each DL CC or each individual ACK/NACK bit.Pass through Channel coding generates single code word.Channel coding including but not limited to repeats, simplex coding, Randt's Miller (RM) are compiled Code, perforation RM coding, tail biting convolutional encoding (TBCC), low-density checksum (LDPC) coding or turbo coding.Although not showing Out, it is contemplated that order of modulation and stock number and can to coded-bit carry out rate-matched.The rate-matched function can be with It is partly covered in channel coding blocks, or is realized in individual functional block.For example, channel coding blocks can pass through pass (32,0) RM coding is executed in multiple control information and obtains single code word, and can execute circular buffering rate-matched.

Modulator by modulating-coding bit b_0, b_1 ..., b_M-1 come generate modulation symbol c_0, c_1 ..., c_L- 1.L is the size of modulation symbol.Modulation scheme is executed by changing the amplitude and phase of transmitting signal.Modulation scheme includes example Such as n phase-shift keying (PSK) (n-PSK) and n quadrature amplitude modulation (QAM) (wherein, the integer that n is two or more).Specifically, modulation scheme packet Include binary system PSK (BPSK), orthogonal PSK (QPSK), 8-PSK, QAM, 16-QAM or 64-QAM.

Divider by modulation symbol c_0, c_1 ..., c_L-1 be divided into time slot.By modulation symbol be divided into the rank of time slot/ Mode/scheme is not limited to specific one.For example, divider can will sequentially be adjusted since 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, c_L/2+1 processed ..., c_L-1 can be assigned to time slot 1.It, can be with when modulation symbol is divided into time slot Interweave (arrangement) modulation symbol.For example, the modulation symbol of even-numbered can be distributed to time slot 0, and can be distributed to time slot 1 The modulation symbol of odd-numbered.Modulation treatment and division processing can sequentially exchanged.

DFT precoder executes DFT precoding (for example, 12 point DFT) about the modulation symbol for being divided into time slot, so as to Generate multicarrier waveform.Referring to fig. 24, modulation symbol c_0, c_1 for being distributed to time slot 0 ..., c_L/2-1 by DFT precoding be DFT symbol d_0, d_1 ..., d_L/2-1, and to time slot 1 distribute modulation symbol c_L/2, c_L/2+1 ..., c_L-1 quilt DFT precoding be DFT symbol d_L/2, d_L/2+1 ..., d_L-1.DFT precoding can be replaced with to another linear operation (for example, Walsh precoding).

Signal (in the time domain) of the extension blocks in the extension DFT precoding of SC-FDMA symbol level.Come using extended code (sequence) The time domain executed in SC-FDMA symbol level extends.Extended code includes quasiorthogonal code and orthogonal code.Quasiorthogonal code includes still unlimited In pseudo noise (PN) code.Orthogonal code includes but is not limited to walsh code and DFT code.Although orthogonal code is retouched for convenience of description The typical case for extended code is stated, but orthogonal code can be replaced with into quasiorthogonal code.Extended code size or the maximum value of SF by Quantity for controlling the SC-FDMA symbol of the transmitting of information limits.For example, if four SC-FDMA symbols are used for one Control information transmitting in a time slot can then use orthogonal code w0, w1, w2 and w3 of length 4 in each time slot.SF Indicate the degree of expansion of control information, and can be related to the antenna multiplexed order of multiplexing order or UE.SF can be depended on System requirements and change into 1,2,3,4 ....Predefined SF or BS it can be believed by DCI or RRC between BS and UE It enables and to indicate SF to UE.For example, if in SC-FDMA symbol of the perforation for controlling information one to emit SRS, have and subtract The extended code of small SF (for example, SF=3 rather than SF=4) can be applied to the control information in corresponding time slot.

When being mapped to the subcarrier in PRB from the signal of operation generation above, and being converted by IFFT Domain signal.CP is added to time-domain signal, and emits generated SC-FDMA symbol by the end RF.

Each operation will be more fully described under the hypothesis for 5 DL CC transmitting ACK/NACK.If each DL CC can emit two PDSCH, then can be 12 bits, including DTX state for the ACK/NACK bit of the PDSCH.? Under the hypothesis of the time extension of QPSK and SF=4, the size (after rate-matched) of encoding block can be 48 bits.Coded-bit 24 QPSK symbols are modulated to, and QPSK symbol is divided into two time slots, each time slot includes 12 QPSK symbols. 12 QPSK symbols in each time slot are converted into 12 DFT symbols by 12 point DFT.12 in each time slot A QPSK symbol is extended to four SC-FDMA symbols using the extended code of SF=4 in the time domain, and is then mapped.Cause To emit 12 bits on [2 bit x, 12 subcarrier x 8SC-FDMA symbol], so encoding rate is 0.0625 (=12/ 192).If SF=4, most four UE can be multiplexed with each PRB.

Figure 25 diagram uses the exemplary structure of the PUCCH format 3 of the OC of SF=5.

Other than the quantity and position of UCI SC-FDMA symbol and RS SC-FDMA symbol, with it is described in reference diagram 25 Identical mode executes basic signal processing operations.Can at the front end of DFT precoder preparatory application extension block.

In Figure 25, RS be can be used and those identical structures used in LTE system.For example, shifting can be recycled Position basic sequence.The multiplexing capacity of data portion due to SF=5 but 5.However, passing through CS interval delta_shift ^PUCCHTo determine RS Partial multiplexing capacity.For example, 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=3 the case where is 12,6 and 4 respectively.In Figure 25, although data Partial multiplexing capacity due to SF=5 but 5, but the multiplexing capacity of the part RS is in Δ_shift ^PUCCHIn the case where be 4.Therefore, Whole multiplexing capacity can be limited to the smaller 4 of the two values.

Figure 26 diagram can be in the exemplary structure of the timeslot-level upper PUCCH format 3 for increasing multiplexing capacity.

It can increase whole multiplexing by being extended to RS using the SC-FDMA symbol level with reference to described in Figure 24 and 25 and hold Amount.Referring to fig. 26, by applying Walsh cover (or the covering of DFT code) to double multiplexing capacity in time slot.Then, it is multiplexed Even if capacity is in Δ_shift ^PUCCHIn the case where be also 8, thus prevent the multiplexing capacity of data portion from reducing.In Figure 26, [y1 Y2]=[1 1], [y1 y2]=[1-1] or its linear transformation (for example, [j j] [j-j], [1 j] [1-j] etc.) can use In the OC of RS.

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

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

As reference, the processing operation of PUCCH format 3 is not limited to the sequence shown in Figure 24 to 27.

Channel selection

Channel selection refers to expression/hair of the specific information carried out by the selection specific resources from multiple resources It penetrates.Common channel selection is the scheme for emitting specific information by the combination of resource and constellation.

Here, physical time-frequency resource and/or sequence resources (for example, CS value) Lai Zhiding resource can be passed through.Example Such as, it in LTE version 8PUCCH format 1/1a/1b, can be selected by the combination of OC, CS and physical resource unit (PRU) Specific resources.It can be assumed that distinguishing the multiple resources for executing channel selection on it by the combination of three kinds of resources above. It is, for example, possible to use the channel selecting methods shown in following table 3.

[table 3]

In table 3 above and in the following description, be expressed as a, b, c ... value can indicate by channel Ch- X (x=1,2,3 ...) in modulation (for example, BPSK, QPSK etc.) caused by constellation value.Alternatively, be expressed as a, b, c ... The value that value can be assigned sequence or assigned code is multiplexed, scrambles or covers, rather than constellation value.Accordingly, with respect to Ch- X be expressed as a, b, c ... value can be the value that can be distinguished therebetween, and do not limit for distinguishing between these values Method.Particularly, in the following description, for convenience of description, about Ch-x be expressed as a, b, c ... value be referred to as Modulation value.

In addition, be expressed as a, b, c ... value can be scheduled particular value, rather than 0.For example, a can be '+1 ', And b can be ' -1 '.

In the example of table 3, even if transmitting same value, which channel can also be depended on for emitting and emitting different Information (that is, ACK or NACK).For example, ACK is emitted, the transmitted value a in the part RS of resource 1 (that is, channel 1), and Transmitted value b in the data portion of resource 1.NACK is emitted, emits a in the part RS of resource 2 (that is, channel 2), and Emit b in the data portion of resource 2.In this way, emit difference for being determined by which resource to emit signal The method of information can be referred to as channel selection.

In table 3, the simple examples without using complicated constellation mapping are shown, but other constellation can be used and reflect It penetrates to be used to emit more information.Table 4 is shown using the two kinds of example for distinguishing constellation mapping (for example, BPSK).

[table 4]

In table 4 above, a, b and c can be the particular value other than 0.Pay attention to, it is preferred that b and c are in constellation On away from each other.For example, a is used as '+1 ', also, 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, for ACK/ACK transmitting, transmitting is modulated to the value of b in resource 1 (channel 1), and And transmitting is modulated to the value of c in resource 1 (channel 1) for ACK/NACK transmitting.In addition, being provided for NACK/ACK transmitting Transmitting is modulated to the value of b in source 2 (channel 2), and transmitting is modulated in resource 2 (channel 2) for NACK/NACK transmitting For the value of c.

Defined in table 5,6 and 7 shown in below used in traditional LTE version 8/9, in TDD for ACK/ The mapping relations of the channel selection of NACK transmitting.In LTE version 8/9, TDD ACK/NACK multiplexing can have and TDD The identical meaning of ACK/NACK channel selection, but they support system (for example, LTE-A or LTE version in following multicarriers 10) there is different meanings in.

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

Specifically, UE uses PUCCH format 1b in ACK/NACK resource in subframe nUpper transmitting bit ' b (0),b(1)'.It can be by generating value ' b (0), b (1) ' and ACK/NACK money according to the channel selection of following table 5,6 and 7 SourceThe multiplexing transmitting of the ACK/NACK as M=2, M=3 and M=4 is shown respectively in table 5,6 and 7.If ' b (0), b (1) ' it is mapped to NACK/ACK, then UE emits ACK/NACK response not in subframe n.

[table 5]

[table 6]

[table 7]

In table 5,6 and 7, HARQ-ACK (i) instruction is used for the HARQ ACK/NACK/ of i-th (0≤i≤3) data cell DTX result.DTX expression be not launched be used for the data cell of corresponding HARQ-ACK (i) or UE detect not yet with The corresponding data cell of HARQ-ACK (i).In this specification, HARQ-ACK is interchangeably used with ACK/NACK.It can be right Most four PUCCH resources are occupied (that is, n in each data cell⁽¹⁾ _PUCCH,0To n⁽¹⁾ _PUCCH,3).Pass through the PUCCH from occupancy The PUCCH resource selected in resource emits the ack/nack signal of multiplexing.In table 5,6 and 7, n⁽¹⁾ _PUCCH,xInstruction is used In the PUCCH resource of practical ACK/NACK transmitting, and ' b (0) b (1) ' indicates emit by selected PUCCH resource two A bit is used QPSK to modulate.For example, if UE has been successfully decoded four data cells, UE as in table 7 By being connected to n⁽¹⁾ _PUCCH,1PUCCH resource come to BS emit (1,1).Because the combination of PUCCH resource and QPSK symbol is not All obtainable ACK/NACK can be indicated, so NACK and DTX are coupled and (are expressed as other than in some cases NACK/DTX)。

Meanwhile in applicable LTE-A (or the LTE version 10) system of the present invention, about for applying channel selecting method Channel selection mapping relations be not particularly limited.For example, can define as shown in table 8 to 10 for emitting ACK/ The channel selection mapping relations of nack message.Table 8 is defined for 2 bit ACKs/NACK mapping relations, and table 9, which defines, to be used for 3 bit ACKs/NACK mapping relations, and table 10 is defined for 4 bit ACKs/NACK mapping relations.

[table 8]

[table 9]

[table 10]

Alternatively, can define as shown in table 11 for 1 bit to 4 bit ACKs/NACK channel mapping relations.? In the example of table 11, b0 can be generated and for 1 bit ACK/nack message transmitting, and b0 and b1 can be generated and use In 2 bit ACKs/nack message transmitting, b0, b1 and b2 can be generated and emit for 3 bit ACKs/nack message, And b0, b1, b2 and b3 can be generated and for 4 bit ACKs/nack message transmittings.

[table 11]

For the UL ACK/NACK of DL transmitting in multicarrier support system

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.In addition, the combination of DL resource and UL resource can be referred to as cell.If asymmetrically configuring DL CC and UL CC, then cell can only refer to DL CC (or UL CC).For example, existing if configuring specific UE with serving cell An one DL CC and UL CC.However, existing if configuring specific UE with two or more serving cells in number In amount the DL CC equal with cell and quantitatively be equal to or less than DL CC UL CC.It is configured when with multiple serving cells When particular UE, the multicarrier environment of quantity of the quantity of wherein UL CC greater than DL CC can be supported.

It can be indicated by the system information in DL transmitted on resources in the carrier frequency of DL and UL resource (in cell Frequency of heart) between association.For example, the combination of DL resource and UL resource can be configured by the association defined by SIB2.

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

In this case, serving cell can be PCell or SCell.For not supporting CA's to be in RRC_CONNECTED UE in state, there is only a serving cells including PCell.Meanwhile for be configured with CA in RRC_CONNECTED UE in state, serving cell refer to include one or more cells of PCell and SCell set.

PCell is the center cell of the control related communication in the serving cell configured in CA environment.PCell is by UE The cell for indicating or using in initial connection establishment process, connection reestablishment procedure or handoff procedure.UE can be only in its PCell Upper reception and transmitting PUCCH.In addition, UE can execute monitoring process, obtains and change for the system information only on PCell Become.UE, BS is supported to can be used including mobilityControlInfo's CA RRCConnectionReconfiguration message is only changed by handoff procedure.

Next, SCell refers to the cell in the serving cell configured in CA environment other than PCell.? PUCCH is not present on SCell.If adding SCell, BS can be by dedicated signaling to the UE offer for supporting CA and in RRC_ The relevant all system informations of operation on the SCell of CONNECTED state.It, can be by via one for SCell The release and addition of the SCell of RRCConnectionReconfiguration message executes the change in system information. BS can emit the dedicated signaling with the parameter different from the parameter for including in the broadcast message on SCell to UE.First After beginning safe activation process, BS can be for UE in addition to PCell is (as the small of serving cell configuration during connecting establishment process Area) except also configure one or more SCell.PCell may be used to provide safety input and higher hierarchy system information, and SCell may be used to provide other DL resource, and provide UL resource as necessary.BS can be used including or not include The RRCConnectionReconfiguration message of mobilityControlInfo passes through RRC connection reconfiguration procedure Independently to add, eliminate or correct SCell.

In CA environment, PhyCellId, SCellIndex and ServCellIndex can be defined as the related ginseng of RRC Number/information element (IE).PhyCellId can have the integer of range from 0 to 503, and be used as the physics of cell Layer identifier.SCellIndex can have the integer of range from 1 to 7, and be used as the identifier of SCell. ServCellIndex can have the integer of range from 0 to 7, and be used as serving cell (PCell or SCell) Identifier.ServCellIndex with value 0 can be applied to PCell, and for SCell, can apply SCellIndex.That is, the cell with minimum (or minimum) cell index in ServCellIndex can be defined as PCell。

In short, 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 configurations.If there is the serving cell of multiple configurations, then one of serving cell It is PCell, and other cells are SCell.If UE has the serving cell of multiple configurations in TDD, which UL indicated The UL-DL configuration that subframe is used to emit the ACK/NACK of the PDSCH for emitting in specific DL subframe can be in all cells In it is identical.

In addition, UE can be measured to BS transmitting from one or more CC in a predetermined C C, such as CSI (including CQI, RI, PMI etc.) UCI and HARQ ACK/NACK.For example, feeding back if necessary to multiple ACK/NACK, then UE can be collected From PCell DL CC and one or more SCell DL CC received ACK/NACK feedback (for example, ACK/NACK be multiplexed or ACK/NACK binding), and it is anti-to the collected ACK/NACK of BS transmitting in the UL CC of PCell that a PUCCH can be used Feedback.

In the present invention, when emitting multiple ack/nack signals for multiple DL transmitting by a PUCCH, structure It is referred to as bundled window at the unit (one or more subframes and/or one or more carrier waves) of multiple DL transmitting.That is, time domain is tied Tie up the ack/nack signal for DL transmitting for referring to being bundled in multiple subframes.The binding of the domain CC refers to being bundled in multiple CC In for DL transmitting ack/nack signal.Time domain/the domain CC binding refers to the use being bundled in multiple subframes and multiple CC In the ack/nack signal of DL transmitting.Although can execute ACK/NACK binding by logic and operation, the present invention is not Be limited to this, and can be used such as logic or other operations.

In addition, the list for actually executing time domain binding using logical AND (or logic or) operation and/or the domain CC bundlees Member can be referred to as practical bundled window.I.e., it is possible to there are one or more practical bundled windows in a bundled window.It changes Sentence is talked about, and the size of bundled window is equal to or more than the size of practical bundled window.Here, can be using for for a DL The space binding (that is, the ACK/NACK for multiple code words is bundled) of multiple ACK/NACK bits of transmitting, and and bundled window Or practical bundled window is unrelated.

It will now be described defined in the 3GPP LTE system, need example for the DL ACK/NACK emitted.Here, working as When emitting ACK/NACK in subframe n, ACK/NACK is related to the DL transmitting in subframe n-k.

It in a tdd system, as shown in Table 12, can be for table 1 about the relationship between subframe n and subframe n-k 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 in subframe n transmitting in subframe n-k DL transmitting ACK/NACK when, in subframe n-k DL transmitting can correspond to the one or more of following three situation.

Situation 1 is one for one or more PUCCH instruction by detecting in one or more subframe n-k when needs When the ACK/NACK feedback of a or multiple PDSCH.Here, k ∈ K, and K is configured according to subframe index n and UL-DL and is changed, And including M element { k₀,k₁,...k_M-1}.Following table 12 shows K:{ k₀,k₁,...k_M-1}.Situation 1 is related to requiring logical One or more PDSCH of normal ACK/NACK feedback.In the following description, situation 1 is referred to as ' for the ACK/ of PDSCH NACK ' or ' for the ACK/NACK ' of the PDSCH with PDCCH.

Situation 2 is when the one or more for needing to discharge the DL SPS indicated in one or more subframe n-k When the ACK/NACK feedback of PDCCH.Here, k ∈ K, and identical index in K expression and the explanation provided in situation 1.Feelings The ACK/NACK of condition 2 indicates to feed back the ACK/NACK of the one or more PDCCH discharged for SPS.Meanwhile when execution pair When the ACK/NACK feedback of DL SPS release, one or more PDCCH of ACK/NACK to(for) instruction SPS activation is not executed Feedback.In the following description, situation 2 is referred to as ' for the ACK/NACK ' of DL SPS release PDCCH.

Situation 3 is when needing the ACK/NACK of the transmitting for one or more PDSCH to feed back, without at one Or the corresponding one or more PDCCH detected in multiple subframes.Here, k ∈ K, and K expression is provided in situation 1 Explanation in identical index.Situation 3 about one or more PDSCH of none or multiple PDCCH, and indicate for The ACK/NACK of one or more SPS PDSCH is fed back.In the following description, situation 3 is referred to as ' for DL SPS PDSCH ACK/NACK '.

In the following description, the PDSCH with corresponding PDCCH, the PDSCH for DL SPS release and no correspondence PDCCH the PDSCH DL transmitting that is collectively referred to as needing ACK/NACK to emit.

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

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

(1) there may be a PCell and one or more SCell.

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

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

It (4) can only there are the PDSCH of no corresponding PDCCH (=SPS PDSCH) on PCell.

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

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

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

In explanation of the invention, time domain binding and/or the binding of the domain CC indicate logic and operation.However, it is possible to pass through all The other methods of such as logic or operation bundle to execute time domain binding and/or the domain CC.That is, what time domain binding or the binding of the domain CC referred to Be for using single PUCCH format ACK/NACK response in, by multiple ACK/NACK tables in multiple subframes or CC Up to the method for the ACK/NACK information with less bit.In other words, time domain binding or the binding of the domain CC are referred to for by M The ACK/NACK information representation of bit is any means of N-bit (M >=N).

It, can be by using PUCCH format 1a/1b, PUCCH format in the system that multicarrier and/or TDD are applied to 3 channel selection emits multiple ACK/NACK bits using the channel selection of PUCCH format 3.For being used for PUCCH format PUCCH resource index, implicit mapping, explicit mapping or the combination implicitly and explicitly mapped can be used.Implicit mapping can be with Use the method for obtaining PUCCH resource index based on the minimum CCE index of corresponding PDCCH.Explicit mapping can make Scheduled concentration is being configured by RRC with indicating or obtaining by the ACK/NACK resource indicator (ARI) in PDCCH The method of PUCCH resource index.

Related to the present inventionly, when the format for emitting multiple ACK/NACK bits with reference to Figure 24 to 27 (for example, retouch The PUCCH format 3 stated) when, explicit resource distribution is substantially based on to execute the resource allocation of PUCCH format 3.

Specifically, the UE for being configured as PUCCH format 3 can be assigned by explicitly (for example, passing through RRC signaling) and is used for The orthogonal resource of the format.Furthermore it is possible to being configured by RRC in scheduled orthogonal resource by for emitting on SCell PDSCH PDCCH in ARI value determine final PUCCH resource.In this case, ARI is used as based on explicit The offset for the PUCCH resource value that ground is transmitted with signal, or can serve to indicate that and to use in one or more PUCCH resource collection Which of.

In order in PDCCH include ARI information, it may be considered that reuse the field of existing PDCCH to be used for ARI purpose Method.PDCCH may include transmission power control (TPC) field.The original purpose of TPC field be control PUCCH and/or The transmission power of PUSCH, and can be made of 2 bits.

As described above, when only emitting ARI on SCell, it can be by the TPC field in the PDCCH on SCell again As ARI.Meanwhile the TPC field in the PDCCH on PCell can be used for the transmission power control of PUCCH.

In 10 system of LTE version, because the PDCCH of the PDSCH for dispatching PCell cannot be received on SCell (that is, the cross carrier wave scheduling for not allowing to carry out the PDSCH of PCell from the PDCCH of SCell), so UE is only received on PCell Meaning to PDSCH can be equal to the meaning that UE only receives PDCCH on PCell.

The explicit ACK/NACK resource allocation configured by RRC signaling can be executed as follows.

Firstly, the PDCCH corresponding with PDSCH (that is, PDCCH for dispatching PDSCH) on SCell may include using The information (for example, ARI) of specific PUCCH resource is obtained in the resource configured from one or more RRC.

Next, if not receiving PDCCH corresponding with PDSCH on SCell and being received on PCell PDSCH can then apply following one of situation.It is possible, firstly, to using the PUCCH resource defined in LTE version 8 (that is, PUCCH format 1a/1b).Second, the PDCCH corresponding with PDSCH on PCell may include for from one or more RRC The resource of configuration obtains the information (for example, ARI) of specific PUCCH resource.

UE can be assumed all PDCCH having the same ARIs corresponding with PDSCH on SCell.

In this way, when ARI information to be defined as only emitting on SCell, if UE is in multicarrier and/or TDD One or more PDSCH (or one or more PDCCH are only received on PCell) for PCell are only received in system, Then because UE not can know that the ARI information emitted from SCell, then the PUCCH format for be used by UE is not can determine that The final resource index of (PUCCH format 3).

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

In various examples of the invention, for convenience of description, wherein UE only receives the one or more for PCell It is called that ' only PCell connects the case where PDSCH (or in which UE only the case where receiving one or more PDCCH on PCell) for short It receives '.Here, the reception definition only PCell reception about UE.If the present invention is applied to multicarrier environment, UE can have There are the cell an of configuration or the cell of multiple configurations.If UE has the cell of a configuration, which be can be PCell, and if UE has the cell of multiple configurations, which can be by a PCell and one or more SCell structure At.The present invention can be applied to one of both of these case or both two kinds of situations.That is, only PCell reception condition can be answered Use CA environment and non-CA environment.

Moreover, as set forth above, it is possible to by new PUCCH format, that is, PUCCH format 3 is used for for leading in a tdd system The ACK/NACK transmitting of the received DL transmitting of multiple DL subframes is crossed, even if when UE includes the cell of a configuration.When UE includes When the cell of multiple configurations, PUCCH format 3 can also be used in FDD or TDD system.I.e., it is possible in CA system or non-CA PUCCH format 3 is used in TDD system.

Moreover, the candidate resource collection for PUCCH format 3 can be configured by RRC in various examples of the invention.It can By the way that the value of ARI information (can be expressed as reusing for the TPC field of PDCCH) is determining or value from the ARI information Obtain the specific PUCCH resource in PUCCH resource Candidate Set.In brief, RRC configuration resource candidate in from The ARI for including in PDCCH is obtained will be by 3 resource of PUCCH format that UE is used.When passing through the PDCCH on SCell as described above When reusing to express ARI of TPC field (2 bit size), ARI has the size of X bit, and X can be defined It is 2.A resource of four PUCCH resource candidates is expressed it is, for example, possible to use 2 bit A RI.

In order to the convenience using associated explanation of PUCCH format 3, by needing the single of orthogonal resource Antenna, which executes, describes the present invention under the hypothesis emitted.It may be evident, however, that the invention is not limited thereto, and even if work as to PUCCH format When the 3 application such as multi-antenna emission diversity scheme of orthogonal space resource transmitting diversity (SORTD), the principle of the present invention is also with phase Same mode is applicable in.

Now, the exemplary hypothesis of the invention for 3 resource allocation of PUCCH format is described based on explanation above.

Resource for PUCCH format 3 can be expressed asAnd it is used for four orthogonal moneys of PUCCH format 3 Source candidate can be expressed asWithAny UE can pass through RRC signaling quilt Assign such four orthogonal resources.RRC signaling for example can be four individual RRC signals.A RRC signaling can be passed through A set being made of to UE notice four orthogonal resourcesReferred to UE with four PUCCH resource candidates can be determined come final in four PUCCH based on the value by addition received ARI instruction A PUCCH resource in resource candidate

Following table 13 shows the example resource allocation for PUCCH format 3 in single-antenna transmission.

[table 13]

Hereinafter, based on explanation above come the various embodiments of detailed description of the present invention.

Embodiment 1

The present embodiment 1 is related in only PCell reception condition (that is, only receiving one or more PDSCH's for PCell Situation or only on PCell receive one or more PDCCH the case where) under using predefined resource allocation method.

In the received situation of only PCell, the resource index of PUCCH format 3 can determine.That is, being received in non-only PCell In the case where, UE can show that PUCCH resource is indexed from ARI received on SCell, and in only PCell reception, UE can be with It is indexed using scheduled PUCCH resource.

Specifically, new index can be made a reservation for, so that UE can determine and use in the received situation of only PCell 3 resource of PUCCH format.New index can have meaning identical with the ARI on SCell.In other words, which can be with It is used to indicate any one of the resource Candidate Set configured by RRC signaling.It can be with the shape of predefined rule (or particular value) Formula indexes to limit, which is used to indicate the resource (example of the particular sorted in resource Candidate Set Such as, first resource or the last one resource).

For example, can determine that the index of 3 resource of PUCCH format can be defined as system under only PCell reception condition Particular value.Alternatively, the index can be configured to eNB particular value or UE particular value by RRC.

Figure 28 is to be shown in the predefined resource allocation determined in the received situation of only PCell for PUCCH resource Flow chart.

In step S2810, UE can configure (for example, RRC signaling) by higher level to receive including for PUCCH lattice The PUCCH resource Candidate Set of four resources of formula 3

In step S2820, when PUCCH format 3 emits for ACK/NACK, UE can determine whether situation is only PCell reception condition.If the determination in step S2820 is the result is that no (that is, non-only PCell reception condition), executes step Rapid S2830, and S2840 is thened follow the steps (that is, only PCell reception condition) if YES.

In step S2830, UE be can be used through the TPC field in one or more PDCCH of SCell again Using indicated ARI come from four PUCCH resource candidate calculating/selection PUCCH resources to be used by (that is, One resource index).

Meanwhile because not receiving PDCCH on SCell in step S2840, UE can be according to predefined rule (or predefined index) selects a PUCCH resource from four PUCCH resource candidates.In the diagram example of Figure 28, in advance Definition rule is that the last one PUCCH resource is selected to index in PUCCH resource Candidate Set.That is, UE can in step S2940 With calculating/selection

After step S2830 or step S2840, UE can be used resource corresponding with the index for calculating/selecting and pass through PUCCH format 3 emits ACK/NACK information.

Embodiment 2

The present embodiment 2 is related to a kind of for making a reservation for other resource index and being used for using the other resource index (that is, the case where only receiving the one or more PDSCH for being used for PCell or only being connect on PCell the case where only PCell is received Receive one or more PDCCH the case where) under PUCCH resource distribute method.

In the received situation of only PCell, it is capable of the other resource index of predetermined PUCCH format 3.That is, UE can be Show that PUCCH resource indexes from ARI received on SCell in the non-received situation of only PCell, and UE can be in only PCell It is indexed in received situation using scheduled other PUCCH resource.Predetermined index in example 1 above be for pair In the predetermined index of one of the PUCCH resource candidate of UE configuration, and embodiment 2 it is different from embodiment 1: make a reservation for and for The other resource index of the PUCCH resource candidate separation of UE configuration.

According to this embodiment, for example, if using 2 bit A RI and defining the resource candidate's that four RRC are configured Set then can transmit an other resource candidate to UE signal by RRC signaling.Then, the resource of RRC configuration is waited Selected works include 5 PUCCH resources index, and one of predetermined resource index (for example, the last one is indexed) can be by It is defined as only using under only PCell reception condition.It is used for alternatively, can discretely be defined with four PUCCH resource candidates The only received resource candidate of PCell.In both above situation the two, only PCell can be only used for UE distribution and connect Receive the reservation resource index (that is, resource index not specified by the ARI on SCell) of situation.Here, whilst it is preferred that It is Chong Die with the resource candidate of four existing RRC configurations that the received other resource candidate of only PCell will be used for, But it can permit overlapping in some cases.

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

In step S2910, UE can configure (for example, RRC signaling) by higher level to receive including for PUCCH lattice The PUCCH resource Candidate Set of four resources of formula 3

In step S2920, when PUCCH format 3 emits for ACK/NACK, UE can determine whether situation is only PCell reception condition.If the determination in step S2920 is the result is that no (that is, non-only PCell reception condition), executes step Rapid S2830, and S2940 is thened follow the steps (that is, only PCell reception condition) if YES.

In step S2930, from 5 PUCCH resource candidates, regular scheduled four PUCCH resources are waited according to the rules The person of choosing is (for example, four low index PUCCH resources With) in, UE can be used logical The TPC field crossed in one or more PDCCH of SCell reuses indicated ARI from four PUCCH resource candidatesCalculating/selection PUCCH resource to be used by.

Meanwhile because not receiving PDCCH on SCell in step S2940, UE can be according to predefined rule To select a PUCCH resource.The predefined rule can be the PUCCH resource candidate selection for configuring from 5 RRC The last one resourceRule.Can limit will not be used to determine in step S2930 in 5 PUCCH resource candidates Four rules in person and the rule weight in step S2940 for determining one in 5 PUCCH resource candidates It is folded.However, in some cases it may the resource candidate that restrictive rule is overlapped selection.

After step S2930 or step S2940, UE can be used resource corresponding with the index for calculating/selecting and pass through PUCCH format 3 emits ACK/NACK information.

Embodiment 3

Embodiment 3 be related to using downlink allocation index (DAI) come in only PCell reception condition (that is, only receiving The case where one or more PDSCH for PCell or only the case where receiving one or more PDCCH on PCell) under The method of PUCCH resource distribution.

In above-described embodiment 1 and 2, it has been described that for obtaining in only PCell reception for PUCCH format 3 Method of the resource index without the use of other physical layer signaling (for example, PDCCH signaling).Embodiment 3 be related to it is a kind of definition and Using the method for the information of the function of being able to carry out ARI in physical layer signal received on PCell, although as in existing side ARI cannot be received in case on SCell like that, since PDCCH being not present on SCell.Specifically, the embodiment is related to Method of the DAI information for including in PDCCH as ARI information is used under only PCell reception condition.

The DAI field in PDCCH is defined in a tdd system, and distributes (or PDSCH scheduling) about DL to assign DAI.When UE emits the ack/nack signal for multiple DL assignment (PDSCH) in a UL subframe, can be obtained from DAI The information of quantity about DL assignment (PDSCH) will emit ack/nack signal for DL assignment (PDSCH).For example, working as UE When to BS transmitting multiple DL are assigned with ack/nack signal (being bundled using ACK/NACK) of (PDSCH), wherein UE fails to connect The situation for receiving a part of (that is, loss) multiple PDCCH is likely to occur.At this point, being transmited to it because UE not can know that The case where PDSCH corresponding with the PDCCH of reception failure, it is possible that there is mistake in ACK/NACK generation.It can be used DAI solves such problems.In existing TDD system, for example, corresponding to N number of DL subframe in a wherein UL subframe In the case of, if sequentially assigning (that is, sequentially count) DAI to the PDCCH emitted in N number of DL subframe, UE can by DAI information in PDCCH, which is known whether, has been correctly received previous PDCCH.

In this embodiment, it is contemplated that DAI when using PUCCH format 3 in the PDCCH of PCell is not used in original The case where beginning purpose, proposes and is re-used as DAI to be used to determine the ARI of PUCCH resource assignment.Specifically, even if in TDD PUCCH format 3 is used in system, DAI information is not needed yet in the operation as the full multiplexer mode of ACK/NACK, in ACK/ Time domain binding or the domain CC (or frequency domain) binding are not executed in the full multiplexer mode of NACK.Therefore, DAI field can be re-used as using In the received ARI of only PCell.

Figure 30 is to be shown under only PCell reception condition DAI field being used for showing for the ARI that PUCCH resource determines The flow chart of example.

In step S3010, it includes for PUCCH format that UE, which can configure (for example, RRC signaling) by higher level and receive, The PUCCH resource Candidate Set of 3 four resources

In step S3020, when PUCCH format 3 emits for ACK/NACK, UE can determine whether situation is only PCell reception condition.If the determination in step S3020 is the result is that no (that is, non-only PCell reception condition), executes step Rapid S3030, and S3040 is thened follow the steps (that is, only PCell reception condition) if YES.

In step S3030, making again for the TPC field in one or more PDCCH by SCell is can be used in UE With indicated ARI from four PUCCH resource candidate calculating/selection PUCCH resources to be used by it (that is, one Resource index).

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

After step S3030 or step S3040, UE can be used resource corresponding with the index for calculating/selecting and pass through PUCCH format emits ACK/NACK information.

Embodiment 3-1

Embodiment 3-1 is related in only PCell reception condition (that is, only receiving the one or more PDSCH for being used for PCell In the case where or only the case where receiving one or more PDCCH on PCell) under in binding subframe using identical ARI value Example.

The terms bundled subframe (or bundled window) used in explanation of the invention is indicated when by a UL PUCCH Emit a unit being made of when responding for the ACK/NACK of the DL subframe in bundled window DL subframe, rather than actually The unit of binding is executed in time domain or the domain CC (or frequency domain).

For example, such as (showing DL relevant episode index K:{ k in table 12 above in LTE version 8TDD system₀,k₁,… k_M-1) shown in, it gives about the one or more DL subframes (subframe n-k) which is used previous and emits for specific UL subframe (the definition of the ACK/NACK response of the DL transmitting in subframe n).In the example description binding subframe by table 12, when When emitting the ACK/NACK response for the DL transmitting in one or more specific DL subframes in specific UL subframe, this Or multiple specific DL subframes are referred to as binding subframe.For example, the binding subframe for UL subframe 2 is DL in UL-DL configuration 4 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, can be emitted as described above by a UL PUCCH for The ACK/NACK response of DL transmitting in multiple DL subframes.Here, when according to embodiment 3 under only PCell reception condition more When detecting one or more PDCCH in a DL subframe, if different by ARI (or DAI) value that corresponding PDCCH is indicated, Do not know which ARI value for calculate/select PUCCH resource.

The problem in order to prevent should be maintained at the ARI value of the PDCCH emitted on PCell in binding subframe in the same manner (that is, value of DAI field).

Embodiment 3-2

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

The terms bundled subframe (or bundled window) used in explanation of the invention is indicated when by a UL PUCCH Emit the ACK/NACK response for DL CC in bundled window and with binding in the presence/absence of it is unrelated when by DL CC structure At a unit, rather than unit of binding is actually executed in time domain or the domain CC (or frequency domain).For example, when applying ACK/ When NACK is multiplexed entirely, the CC of binding can have meaning identical with the quantity of CC configured for UE.

If using PUCCH format 3 in TDD or FDD system, can occur in which as described above through a UL PUCCH emits the case where responding for the ACK/NACK of multiple DL CC.Here, ' emitting the ACK/NACK for multiple DL CC Response ' meaning can indicate that there are DL transmittings in PCell and one or more SCell.At this point, if PCell's ARI value in PDCCH is different from the ARI value in the PDCCH of SCell, then does not know and calculated/selected using which ARI value PUCCH resource.

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

Embodiment 3-3

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

When (for example, when multiple CC and multiple subframes are a binding units) considering both embodiment 3-1 and 3-2, If the ARI value in corresponding cell or corresponding subframe is different, calculating/selection of PUCCH resource may be unclear.Cause This is maintained in the PDCCH in multiple subframes other than the ARI value being maintained in PDCCH on PCell and SCell is equal ARI value it is equal.

Embodiment 4

Embodiment 4 be related to it is a kind of using TPC field come in only PCell reception condition (that is, only receiving for PCell One or more PDSCH the case where or only on PCell receive one or more PDCCH the case where) under PUCCH resource divide The method matched.Embodiment 4 can be applied to the two kinds of situations wherein applied or ACK/NACK is not applied to be multiplexed entirely.Embodiment 4 Wherein application or not two kinds of situations of application space binding (ACK/NACK for multiple code words is bundled) can also be applied to.

In example 3 above, it has been described that for even determining PUCCH resource (example in only PCell reception Such as, the resource of PUCCH format 3) resource index without the use of other physical layer signaling method.Embodiment 3 is related to working as DAI It is not used as being used for when original applications (for the purposes for the index that DL distribution (or PDSCH is dispatched) sequentially assigns) using DAI The example of ARI purpose.Therefore, when in a tdd system use PUCCH format 3 when, if support time domain binding or the domain CC (or frequency Domain) binding, then DAI information is needed for original purpose, to generate correct ACK/NACK information.

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

(that is, there are PDCCH transmittings on SCell) under non-only PCell reception condition, as described above, on SCell TPC field is reused for ARI.However, under only PCell reception condition, because there is no the transmitting of TPC field on SCell, So the new method for emitting correct ACK/NACK must be defined.

According to embodiment 4, under only PCell reception condition, according to the one or more that pre-defined rule is determining on PCell TPC field in specific PDCCH can be used for original transmission power control purpose, and one or more other PDCCH TPC field can be used for ARI purpose.UE can be used only in the one or more determined according to pre-defined rule on PCell The TPC field of specific PDCCH is come for original power control purpose, and other one or more are received on PCell When PDCCH, the TPC field of one or more corresponding PDCCH can be construed to ARI by UE.

If TPC field is not used in original purpose, UE can the loss of energy include TPC field for power control PDCCH, or if BS does not dispatch PDCCH, may slightly reduce the dynamic controlling determined for the UL transmission power of UE Energy.However, the TPC value in PDCCH is not absolute value but for the opposite deviant of previous transmission power.Moreover, i.e. It updates UE TPC value once or twice, preset transmission power can also be kept.In addition to using the TPC word in PDCCH Section transmission power control method except, also provide supplement Poewr control method (this deviate the scope of the present invention, and because This, will not be described in detail).Therefore, the loss of TPC value does not have considerable influence for network performance.

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

As the first example, the TPC field definition of the PDCCH emitted in the n-th subframe of binding subframe can be used In original purpose.Here, n can be the value for being used to indicate one or more subframes of part in binding subframe.For example, if N, then can be determined as being used to indicate the value of the 0th subframe or the last one subframe by one of instruction binding subframe.Furthermore, it is possible to root N is differently determined according to the quantity (or size of binding subframe) of binding subframe.In similar mode shown in the table 12, The quantity of binding subframe for example can be 1,2,3,4 or 9.Alternatively, different numbers can be bundled according to the binding scheme newly defined The subframe of amount.Moreover, n can indicate the set of multiple subframes in binding subframe.For example, when n is 0 and 1, in binding The TPC field of the PDCCH emitted in the 0th and the 1st subframe in frame can be used for original purpose.Therefore, if n is with multiple Value, the then quantity that the PDCCH of the test described below that retracts is used for being received increase the quantity of n value.For example, if n has There are two value, then being received come the quantity of the PDCCH for the test that retracts should be 2.Exemplary theory below the present invention In bright, for convenience of description, n has a value.

As the second example, the TPC field in binding subframe in the PDCCH with n-th of DAI value be can be defined as For original purpose.Here, n can be 0,1,2,3 ... one of.Alternatively, if DAI value is construed to 1,2,3,4 ..., N can then be determined as to 1,2,3,4 ... a value of.In this case, though the full multiplexer mode of ACK/NACK (wherein Not the case where not applying time domain or the domain CC (or frequency domain) to bundle) in, can also include in one or more PDCCH on PCell DAI field.Furthermore, it is possible to determine n in the form of the set of multiple values.For example, this can indicate having when n is 0 and 1 There is the TPC field in the PDCCH of the 0th and the first DAI value for original purpose.Alternatively, when being construed to DAI value since 1 When, if n is 1 and 2, the TPC field in the PDCCH with the first and second DAI values can be indicated as being used for original Purpose.Therefore, when n has multiple values, the quantity of the PDCCH for the rollback test for being received to be used to describe later increases n The quantity of value.For example, if it should be 2 that n tool, which there are two value, is received come the quantity of the PDCCH for the test that retracts,.At this In explanation below invention, for convenience of description, there is n a value to be used as example.

In the second example above, what DAI value can indicate to distribute with dibit size to UE is used for one or more Continuous (sequence) counter of PDCCH.The value of the actual transmission of DAI field can be can be construed to 1,2,3 and of DAI value by UE 4 one of 0,1,2 and 3 (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 UE the value can be construed to first, second, Third 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) the first PDCCH of instruction.

The value of the actual transmission of DAI field can be 0,1,2 or 3, and UE the value can be construed to first, second, Third 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) the first PDCCH of instruction.

In short, the practical DAI value 00,01,10 and 11 for including in PDCCH can be respectively mapped to be explained by UE DAI value 1,2,3,4.

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

Figure 31 is to be shown under only PCell reception condition TPC field being used for showing for the 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 is used for Original purpose, and the TPC field of other one or more PDCCH is re-used as ARI.

In step S3110, it includes for PUCCH format that UE, which can configure (for example, RRC signaling) by higher level and receive, The PUCCH resource Candidate Set of 3 four resources

In step S3120, when PUCCH format 3 emits for ACK/NACK, UE can determine whether situation is only PCell reception condition.If the determination in step S3120 is the result is that no (that is, non-only PCell reception condition), executes step Rapid S3130, and S3140 is thened follow the steps (that is, only PCell reception condition) if YES.

In step S3130, making again for the TPC field in one or more PDCCH by SCell is can be used in UE With indicated ARI come from four PUCCH resource candidate calculating/selection PUCCH resources to be used by it (that is, one A resource index).

Meanwhile in step S3140, UE can determine the quantity of received PDCCH whether be 1.Because when in SCell On execute step S3140 when not receiving PDCCH, so the quantity of the received PDCCH of institute indicate it is received on PCell The quantity of PDCCH.If the definitive result in step S3140 is to be (that is, the quantity of received PDCCH is on PCell 1) S3150, is thened follow the steps, and if the definitive result in step S3140 is no (that is, received on PCell 1) quantity of PDCCH is greater than, then follow the steps S3160.

In step S3150, if UE only receives a PDCCH on PCell, the TPC of PDCCH is can be used in UE Field is used for original purpose (power control), and because UE, which can be determined, not to be received without any other PDCCH ARI value.In this case, UE is limited to run under traditional 8 mode of LTE version.This can be referred to as in fall-back mode Operation.Fall-back mode is identical as the ACK/NACK of the PUCCH format 1a/1b using usual definition transmitting operation, and therefore, will Description is omitted.In step S3140 about the quantity of received PDCCH whether be that 1 determination can be referred to as Retract test, where it is determined whether using fall-back mode.

Meanwhile because executing step S3160 when the quantity of PDCCH received on PCell is greater than 1, UE can be with Purpose is used for original using the TPC field in one of PDCCH, and can be by the TPC of other one or more PDCCH Field is construed to for ARI.Then, UE, which can be used, reuses meaning by the TPC field in the PDCCH of PCell The ARI shown come from four PUCCH resource candidate calculating/selection PUCCH resources to be used by it (that is, a resource Index).

After step S3130 or step S3160, UE can be used resource corresponding with the index for calculating/selecting and pass through PUCCH format 3 emits ACK/NACK information.

In the diagram example of Figure 31, explanation is given under following hypothesis: UE, which is only checked, receives (or detection) PDCCH quantity, and when the quantity of received PDCCH be 1 when, the TPC field of corresponding PDCCH is used for original mesh 's.

However, if the quantity of received PDCCH be that the TPC field of 1, PDCCH can be used for original purpose or can To be reused for ARI purpose.Therefore, when the quantity of received PDCCH be 1 when, always do not execute fall-back mode operation, and Preferably, detailed determination is executed.

Figure 32 is to be shown in the received situation of only PCell TPC field being used for the ARI that PUCCH resource determines Another exemplary flow chart.In the example of Figure 31, it is assumed that according to the TPC for 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 diagram example of Figure 32, omit it is identical with the operation of Figure 31 operate (step S3210, S3220, S3230 and S3240 explanation).

It is executed when the definitive result of step S3240, which is, is (that is, when the quantity of PDCCH received on PCell is 1) Step S3250.In step S3250, whether the PDCCH for determining that this is received is predefined PDCCH (that is, PDCCH Whether TPC field is used for original purpose).For example, it may be determined that received PDCCH whether be binding subframe the first subframe In PDCCH.As another example, can determine received PDCCH whether there is DAI value 1 (hereinafter, DAI=1) PDCCH.If it is determined that result be it is yes, then follow the steps S3260, and if not, then follow the steps S3270.

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

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

When the definitive result of step S3250 is no, step S3270 can also be executed.That is, if the received PDCCH of institute Quantity be 1, then because corresponding PDCCH is not the PDCCH that wherein TPC field is used for original purpose, UE can be identified The TPC field of a corresponding PDCCH is reused for ARI out.The ARI for carrying out the TPC field of self-corresponding PDCCH can be used in UE Value calculates/selects to be used by it the PUCCH resource in four PUCCH resource candidates (that is, a resource rope Draw).

In step S3270, resource corresponding with the index for calculating/selecting, which can be used, in UE comes through PUCCH format 3 Emit ACK/NACK information.

Embodiment 4-1

Embodiment 4 is related to the case where only PCell is received (that is, only receiving the one or more for PCell The case where PDSCH or only the case where receiving one or more PDCCH on PCell) under in binding subframe using identical The example of ARI value.

The terms bundled subframe (or bundled window) used in explanation of the invention is indicated when by a UL PUCCH Emit a unit being made of when responding for the ACK/NACK of the DL transmitting in the DL subframe in bundled window DL subframe, Rather than the unit of binding is actually executed in time domain or the domain CC (or frequency domain).

For example, such as (showing DL relevant episode index K:{ k in table 12 above in LTE version 8TDD system₀,k₁,… k_M-1) shown in, the one or more DL subframes (subframe n-k) previous about which are given for emitting in specific UL Subframe (the definition of the ACK/NACK response of the DL wireless communication system in subframe n).It describes to bundle in the example by table 12 In subframe, as the ACK/NACK that transmitting emits the DL in specific one or multiple DL subframes in specific UL subframe When response, this specific one or multiple DL subframes be referred to as and bundle subframe.For example, being used for UL subframe 2 in UL-DL configuration 4 Binding subframe be DL subframe 12,8,7 and 11, also, be DL subframe 6,5,4 and 7 for the binding subframe of UL subframe 3.

If in TDD use PUCCH format 3, can be emitted as described above by a UP PUCCH for The ACK/NACK response of DL transmitting in multiple DL subframes.Here, according to the above embodiments 4, the case where only PCell is received Under multiple PDCCH are detected in multiple DL subframes.If as having indicated by the PDCCH for the TPC field for being re-used as ARI ARI (or TPC) value is different, then ambiguous to be, which ARI value for calculate/select PUCCH resource.

Here, in addition to having the PDCCH for being confirmed as according to predefined rule the TPC field for original purpose for example, PDCCH with DAI=1) except, have be re-used as ARI TPC field PDCCH can correspond to PDCCH (for example, PDCCH with the DAI value (hereinafter referred to as DAI > 1) greater than 1).

Therefore, the problem in order to prevent should equally be maintained at emitting on PCell in binding subframe, have quilt The PDCCH of the TPC field of ARI is re-used as (that is, other than there is the PDCCH for the TPC field of original purpose PDCCH ARI value (that is, value of TPC field)).

Embodiment 4-2

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

The CC (or bundled window) of the terms bundled used in explanation of the invention indicate with binding in the presence/absence of It is unrelated, when emitting 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 of binding is actually executed in time domain or the domain CC (or frequency domain).For example, when applying When ACK/NACK is multiplexed entirely, the CC of binding can have meaning identical with the quantity of CC configured for UE.

If using PUCCH format 3 in TDD or FDD system, can be sent out as described above by a UL PUCCH Penetrate the ACK/NACK response for multiple DL CC.Here, transmitting can be with for the meaning of the ACK/NACK response of multiple DL CC Corresponding to wherein the case where there are DL transmittings on PCell and one or more SCell.At this point, if being used as having ARI value in the PDCCH of the TPC field of ARI on PCell is different from the ARI value in the PDCCH on SCell, then obscures not It is clear, which ARI value for calculate/select PUCCH resource.

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

Here, can equally be maintained on PCell, in addition to being determined according to predefined rule using TPC field Come the PDCCH (for example, PDCCH with DAI > 1) being used for except original purpose PDCCH (for example, PDCCH with DAI=1) ARI value and the ARI value on SCell.

Embodiment 4-3

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

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

Here, can equally keep on PCell in addition to being determined to according to predefined rule using TPC word The PDCCH that section is come except the PDCCH (for example, PDCCH with DAI=1) for original purpose is (for example, have DAI > 1 PDCCH ARI value).

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

DAI field value is used as the stored counts device of the PDCCH of each cell.That is, DAI value is in each of cell Sequentially increased 1 in a PUCCH.Always there are PDCCH in all subframes.

In the diagram example of Figure 33, on PCell, there is the PDCCH for DL distribution in first and third subframe. DAI value is 0 in the PDCCH of the first subframe, and is 1 in the PDCCH of third subframe.On SCell, distributed for DL PDCCH in sequentially provide DAI value.In Figure 33, diagram DAI value 0,1,2,3,0,1,2,3 ..., but in terms of the viewpoint of UE, These values have with DAI value 1,2,3,4,1,2,3,4 ... identical meaning.

Relatively with above-described embodiment 4, according to the DAI value on PCell, the TPC field in PDCCH can be used for original Beginning purpose or ARI purpose.For example, in the PDCCH that the DAI value wherein on PCell is 0 (or being 1 in terms of the viewpoint from UE) TPC field, that is, the TPC field in PDCCH in the first subframe of the PCell in Figure 33 is for original purpose (that is, power Control), and the TPC field in another PDCCH on PCell is reused for ARI purpose.

With the above embodiments 4-1 into 4-3 relatively, can equally be maintained at binding subframe and/or binding cell In ARI value.For example, if applying bundled window, UE in four subframes and five cells in the diagram example of Figure 33 It can be assumed that the value of the TPC field (that is, the TPC field for being used for ARI purpose) of the PDCCH on PCell and SCell is identical, remove TPC field in the first subframe of PCell is (except wherein, 0) DAI is.

Embodiment 5

Embodiment 5 is related in only PCell reception condition (that is, only receiving the feelings of one or more PDSCH for PCell Condition or only the case where receiving one or more PDCCH on PCell) under the side that is distributed using TPC field for PUCCH resource Method.Embodiment 5 is applied to part ACK/NACK binding.Part binding refers to only in the time domain or in the domain CC (or frequency domain) Binding.

DAI field is essentially available for original purpose (that is, in each cell as in example 4 above On PDCCH stored counts device), 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.Specific PDCCH can be determined as to the n-th son in binding subframe The PDCCH (describing this part in the embodiment 4 having been described above, and therefore, the repetitive description thereof will be omitted) of frame.Alternatively, Wherein PDCCH of the TPC field for original purpose can be determined based on DAI value.

The example of the upper surface of Figure 31 or 32 can be used as basic operation be applied to embodiment 5 with being substantially the same, and save The repeated explanation provided in the embodiment 4 slightly having been described above.

Hereinafter, description is used for original purpose using TPC field based on DAI value when application obscure portions ACK/NACK is bundled Or the method detailed of ARI purpose.

Firstly, 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, the part ACK/NACK tie-in mode (being applied to time domain binding or the domain CC (or frequency domain) binding) In, it can include DAI field in one or more PDCCH on PCell.Here, should be determined based on pre-defined rule The value for the DAI field for including in one or more PDCCH of PCell, and the present invention explained below building in detail to it View.

When the part application ACK/NACK bundlees, if the TPC field in the PDCCH of DAI=n is used for original purpose (power control) can then determine that the DAI field of one or more PDCCH is as follows in various ways.

In traditional (LTE version 8) tdd mode, DAI indicates the accumulated value to the UE PDCCH distributed, and if simple DAI can be then used as the accumulation on whole cells (or CC) to the UE PDCCH distributed to multicarrier environment application DAI by ground Value.For example, as shown in Figure 34, when bundling in four sub-frames and on two CC using ACK/NACK, can determine DAI Value is so that the DAI value side that CC index increases in bundled window is increased up.However, it is difficult to which the program is applied to part bundle It ties up.Therefore, it configures wherein in the LTE version 10TDD mode of multiple CC (or cell), it is desirable to provide another kind is for determining The method of DAI value.

Figure 35 is to be shown in the exemplary figure that DAI value is determined in CA TDD system.

As an example, DAI value can indicate in multiple subframes of each cell to the cumulative number of the UE PDCCH distributed It measures (Figure 35 (a)).For example, such method for determining DAI value is preferably used when binding when applying in the time domain.It can be with The cumulative amount of PDCCH is applied in a manner of counting in the PDCCH in all subframes in a radio frame.Alternatively, can With the side to count the PDCCH in practical bundled window (for actually executing the unit of ACK/NACK binding) in the time domain Formula applies the cumulative amount of 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 determined as 0,1 and 2, and this is using DAI field as tired The example of product counter, it is the first PDCCH, the 2nd PDCCH and third which, which is used to indicate corresponding PUCCH respectively, PDCCH。

As another example, DAI value can indicate to distribute in multiple CC (or cell) to UE in each subframe PDCCH sum (Figure 35 (b)).It is determined for example, such DAI value is preferably used when application obscure portions bundle in the domain CC Method.The sum of PDCCH can be determined as to the quantity of the PDCCH in all CC configured for UE.Alternatively, can incite somebody to action The sum of PDCCH is determined as in the practical bundled window in the domain CC (for the practical unit for executing ACK/NACK binding) 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 using DAI Field is the example of 3 indicator as the sum for the PDCCH being used to indicate in corresponding subframe.

Alternatively, the PDCCH distributed in the multiple CC (or cell) that DAI value can be determined as in each subframe to UE Stored counts device.Can according to the ascending order of the CC index (or cell index) in all CC configured for UE or according to The ascending order of CC index (or cell index) in practical bundled window in the domain CC counts PDCCH's for each PDCCH Cumulative amount.For example, in the example of Figure 35 (b), by the DAI value in third subframe be determined as DAI=0 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 the tired of the PDCCH distributed in practical bundled window in the time domain Product counter (that is, if DAI value being resetted on each CC), can equally apply use in addition to having on PCell The TPC field of external PCell and the PDCCH on multiple SCell of PDCCH of specific DAI value (for example, DAI=0) be used for The embodiment of the present invention of ARI purpose.

Meanwhile as shown in Figure 35 (b), if DAI is used as dividing in the practical bundled window in the domain CC (or frequency domain) The sum (or stored counts device) of the PDCCH matched is then likely difficult to using in addition to having the specific DAI value on PCell The TPC field of the external PCell and the PDCCH on multiple SCell of the PDCCH of (for example, DAI=0) carry out the sheet for ARI purpose The embodiment of invention.

For example, it may be assumed that distributing PDCCH to specific UE in the first subframe and the second subframe, and not in SCell Upper distribution PDCCH.Although the situation is received corresponding to only PCell, by the DAI value of the received PDCCH of UE in the two sons (for example, DAI=0) identical in frame (if DAI field be used as the PDCCH in corresponding subframe sum indicator or Stored counts device, then according to above it is assumed that 0) DAI value is.Then, ambiguous for UE to be, it determines on PCell The TPC field of which PDCCH in two PDCCH is used for ARI purpose, and the TPC field of which PDCCH is used for original mesh 's.It in other words, cannot be using in addition to tool if determining DAI value by the reset schemes of the DAI value of each subframe Have the external PCell's and the PDCCH on multiple SCell of the PDCCH of the specific DAI value (for example, DAI=0) on PCell TPC field carrys out the embodiment of the present invention for ARI purpose.

In order to solve the problems, such as above, method can be determined using different DAI values on PCell and SCell.For example, On SCell, DAI is used as the stored counts of the PDCCH distributed in the practical bundled window in frequency domain (or the domain CC) Device, and on PCell, DAI is used as the instruction of the sum of the PDCCH distributed in practical bundled window in the time domain It accords with (or stored counts device).

Alternatively, needing for the DAI at least on PCell to be defined as PDCCH's in the time domain to apply the present embodiment Stored counts device.Therefore, the DAI of one or more PDCCH on PCell is used as practical binding window in the time domain The stored counts device of PDCCH distributed in mouthful, and can be come in the mode identical or different with the DAI that is used on PCell Use the DAI of one or more PDCCH on SCell.

In it will be described below example of the invention, it is assumed that the DAI field of PDCCH is used as follows.

Firstly, the DAI field in PDCCH is used as dividing in multiple subframes in the binding of each CC is checked The stored counts device of the PDCCH matched.That is, independently determining DAI value on each CC.Here, the bit value 0 of DAI field, 1, 2 and 3 indicate respectively stored counts 1,2,3 and 4.That is, the bit value for being expressed as 0,1,2 and 3 in terms of the viewpoint of DAI field can also To be expressed as 1,2,3 and 4 in terms of the viewpoint for the DAI value explained by UE.

Next, the DAI field of PDCCH is also used as on multiple CC in the bundled window in each subframe The indicator 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, 0,1,2 and 3 bit value is expressed as in terms of the viewpoint of DAI field can also be expressed as 1,2,3 and in terms of the viewpoint by UE 4。

The diagram of Figure 36 to 39 uses the various examples of the DAI field in the binding of the domain CC.In the example of Figure 36 to 39, figure Show the 4DL-1UL configuration for 5 CC of UE configuration and in TDD (that is, collecting for the DL transmitting in four DL subframes ACK/NACK response is responded with the PUCCH by a UL subframe to emit).In addition, in the diagram example of Figure 36 to 39, bundle Tying up window includes 5 CC and four subframes.However, the largest amount that wherein practical bundled window is illustrated in Figure 36 to 39 be 4, 5 or 2 the case where.

Wherein not on PCell, using the example of the domain CC binding, (the practical bundled window in the domain CC is most for Figure 36 diagram 4) big size is.In this case, the DAI field of PCell is used as the accumulation of the PDCCH distributed to the subframe on PCell Counter.The DAI field of SCell is used as the indicator of the sum to the SCell PDCCH distributed, in addition at each Except PCell in subframe.

Figure 37 diagram is wherein not on PCell using the example (largest amount of the practical bundled window in the domain CC of the domain CC binding 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 the instruction in each subframe to the sum of the PCell and SCell PDCCH distributed Symbol.Therefore, according to the DAI of SCell, UE be able to know that in corresponding subframe by BS distribution PDCCH sum (that is, The sum of PDCCH on both PCell and SCell).UE can be used the DAI of PCell and about the PDCCH's distributed The information of sum fails the PDCCH for detecting/receiving in practical bundled window to determine whether there is UE.Therefore, can Efficiently perform the domain the CC ACK/NACK binding in corresponding subframe.

For example, in the diagram example of Figure 37, if in the PDCCH detected on SCell by UE in the second subframe DAI value be 2, then UE can identify that the sum of the PDCCH distributed on PCell and multiple SCell is 3.Herein, it can be assumed that UE does not receive PDCCH in SCell#2.In this case, it cannot only not received by the DAI value on SCell to determine To PDCCH whether be PDCCH in practical bundled window (that is, on SCell) or other than practical 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, which can be confirmed in first and third subframe on PCell, is sequentially provided DAI value, and therefore UE is not present not in confirmation The PDCCH that can be detected on PCell.As a result, UE is able to know that PDCCH detection is lost in one of SCell in the second subframe The case where losing.

The example that Figure 38 diagram wherein independently applies the domain CC to bundle with PCell or SCell be (the practical bundled window in the domain CC 5) largest amount is.In this case, the DAI field of PCell is used as the tired of the PDCCH distributed to the subframe on PCell Product counter.The DAI field of SCell can serve to indicate that distributes on both PCell and SCell in each subframe The sum of PDCCH.Therefore, UE can be known by the DAI of SCell in subframe by BS distribution PDCCH sum ( The sum of PDCCH in both PCell and SCell).Because of the quantity of PDCCH of the DAI value instruction in practical bundled window, So UE may determine whether that UE fails the PDCCH for detecting/receiving in practical bundled window.Therefore, Neng Gouyou Effect ground executes the domain the CC ACK/NACK binding in corresponding subframe.

Figure 39 illustrates the case where largest amount of the wherein practical bundled window in the domain CC is 2.At this point, not applied on PCell The domain CC binding, and it is possible to which configuration has two practical 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 It is except the PCell in each subframe, distribute on SCell (most two SCell) in practical bundled window The indicator of the sum of PDCCH.

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

Therefore, under only PCell reception condition, the TPC wherein in binding subframe on PCell can equally be kept Field is reused for the ARI value of the PDCCH (that is, other than the wherein PDCCH of TPC for original purpose) of ARI purpose.Separately Outside, it on the CC of binding, can be equally maintained at the value for the field (=TPC field) for being used for ARI purpose on SCell Value on PCell for the field (=TPC field) of ARI purpose.Moreover, can equally be kept on binding CC and subframe In addition to being confirmed as using TPC field come the PDCCH for original applications according to predefined rule (for example, having on PCell The PDCCH of DAI=1) except the PDCCH PDCCH of DAI > 1 (for example, with) ARI value.Related to thisly, above 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.For clarity, Omit the explanation of repeating part.

UL ACK/NACK transmitting for the DL SRS transmitting in multicarrier support system

8 system of LTE version supports SPS.If having activated DL SPS transmitting, use can be allocated in advance by PDCCH In the time/frequency resource of SPS transmitting, and the PDSCH of no corresponding PDCCH can be emitted by the resource of distribution.

ACK/NACK feedback relevant to SPS can be divided into two types.One seed type is the transmitting pair in subframe n In ' ACK/NACK of the PDCCH ' for the DL SPS release that instruction is detected in one or more n-k by UE is fed back.Another type Type is the ACK/ emitted in subframe n for ' emitting in one or more subframe n-k without the PDSCH of corresponding PDCCH ' NACK feedback.First seed type corresponds to following situations: where if there are PDCCH, (wherein, k can in the n-th-k subframes To be one or more values), then emit in the n-th subframe and the ACK/NACK of the PDCCH is fed back.Second of type corresponds to Following situations: where if receiving SRS transmitting in the n-th-k subframes of not other PDCCH after SPS activation, Regularly emit the ACK/NACK feedback for corresponding SPS transmitting in n-th of subframe.For relevant to SPS transmitting detailed Describe in detail it is bright, can be with reference paper 3GPP TS 36.213.

It is substantially based on the CCE index of PDCCH and is used for what ACK/NACK was fed back in 8 system of LTE version to determine PUCCH resource index.If the ACK/NACK response in a PUCCH in the n-th subframe includes in the n-th-k subframe One or more PDCCH (including general PDCCH and instruction DL SPS release PDCCH) ACK/NACK response, then may be used To show that PUCCH resource indexes from the CCE index of PDCCH.However, if should only emit for not having in the n-th-k subframe There is the ACK/NACK of the SPS of PDCCH to respond, then not can determine that the PUCCH resource index for ACK/NACK response.In order to solve Such problems is indicated in advance by RRC signaling for there is only ' without corresponding PDCCH's in 8 system of LTE version The PUCCH resource indexed set of the case where PDSCH transmitting ' (that is, SPS PDSCH emits) by four PUCCH resources (for example, indexed The set constituted).Moreover, determining whether to provide using PUCCH by the TPC field in the PDCCH of instruction SPS activation One PUCCH resource of source indexed set.It is defined in the table 14 being shown below in the PUCCH resource index for DL SPSMapping relations between the value of TPC field.

[table 14]

If executing above-mentioned DL SPS transmitting in multicarrier support system, must provide in view of DL SPS emits ACK/NACK launching technique.

The each embodiment of the invention to this is described under the premise of following: being similar to the above embodiments 4 and 5, for spy Determine the PCell of UE the first PDCCH (with 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 be used for ARI purpose.It is worth noting that, this The hypothesis of sample is that for clarity, and application example of the invention is without being limited thereto.I.e., it is possible to be provided by other methods ARI information.

It is (following for ' emitting without the PDSCH of corresponding PDCCH ' in the n-th-k subframe when emitting in the n-th subframe Referred to as ' the not SPS ' of PDCCH) ACK/NACK response when, the SPS of not PDCCH can be received in the n-th-k subframe, and And in addition to this it is possible to detect a PDCCH.Then, need to emit ACK/NACK for PDCCH in response to for not having There is the ACK/NACK of the SPS of PDCCH to respond.Here, if a PDCCH detected is the first PDCCH (for example, having DAI =1 PDCCH), then because the TPC field of PDCCH is used for original purpose, which is when UE does not receive ARI information When.Therefore, UE not can determine that the resource index for PUCCH format 3.Hereinafter, being used to solve the problems, such as sheet above for description The various embodiments of invention.

In the following description, ACK/NACK is needed to emit in one of three kinds of situations below.In short, situation 1 be for ' ACK/NACK of the PDSCH ' with PDCCH, situation 2 are for ' DL SPS discharges the ACK/NACK of PDCCH ', and situation 3 It is for ' the ACK/NACK of DL SPS PDSCH '.

Situation 3 can be referred to as ' without the PDSCH ' of corresponding PDCCH, for ' the not ACK/ of the SPS ' of PDCCH NACK or referred to as ' SPS ' ACK/NACK.In situation 1, ' PDCCH of the PDSCH ' with PDCCH can be referred to as ' the PDCCH ' corresponding to PDSCH.

Embodiment 6

Embodiment 6 is related to the method for always emitting ACK/NACK response using PUCCH format 3.

The 3 resource index collection of PUCCH format of SPS can be only used for UE instruction by RRC signaling.For example, can be to UE There is provided about in the form of shown in the table 13 above byWithThe collection of composition The information of conjunction.Furthermore it is possible to use PUCCH format 3 by the TPC field being used to indicate in the PUCCH that SPS is activated come specified Which resource index of resource index collection.

As an example, may be selected and used logical when needing only to feed back the ACK/NACK of the SPS of not PDCCH Cross specific 3 resource index of PUCCH format indicated by the SPS activation PDCCH in the set of RRC configuration.I.e., it is possible to use PUCCH format 3 is only used for the ACK/NACK of the not SPS of PDCCH to emit.

As another example, method below can be applied to wherein need for ' not the SPS ' of PDCCH and ' there is the case where ACK/NACK of a PDSCH ' of PDCCH is fed back.

First method is selection and activates 3 resource index of PUCCH format indicated by PDCCH using by SPS.That is, Also PUCCH format 3 can be used to emit for ' the not SPS ' of the PDCCH and ' ACK/ of a PDSCH ' with PDCCH NACK response.

According to whether ' including ARI information in the PDCCH ' corresponding to PDSCH, second method is further drawn at one It is divided into two methods.

When one ' PDCCH ' corresponding to PDSCH be do not include ARI information PDCCH (for example, wherein the first DAI (DAI =1) PDCCH) when, it may be selected and used and 3 resource index of PUCCH format indicated by PDCCH is activated by SPS.That is, i.e. Make from ' PDCCH ' corresponding to PDSCH has not been obtained to ARI information, PUCCH format 3 can be used also to emit for ' not having The SPS ' of PDCCH and ' the ACK/NACK response of a PDSCH ' with PDCCH.

If one ' PDCCH ' corresponding to PDSCH be include ARI information PDCCH (such as without the first DAI (DAI > 1) PDCCH) (this is it may is that when UE loss has the PDCCH of the first DAI), then it uses by ' corresponding to PDSCH's 3 resource index of PUCCH format of ARI value indicated by TPC field in PDCCH ' can be selected and be used.

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

Embodiment 7

Embodiment 7 is related to for operating for ' only ' always in fall-back mode not transmitting of the SPS of PDCCH The method of ACK/NACK.Here, fall-back mode refers to being emitted according to the ACK/NACK of the operation defined in LTE version 8, example Such as, emitted using the ACK/NACK of PUCCH format 1a/1b.On the other hand, about for ' the not SPS ' of PDCCH and other DL The ACK/NACK transmitting of transmitting (PDSCH with PDCCH), can be used PUCCH format 3.

For this purpose, can be used to emit the PUCCH format 1a/1b resource index of ' only ' SPS to UE instruction by RRC signaling Collection.It 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 is activated, which that use PUCCH resource indexed set can be specified by activating the TPC field in PDCCH in SPS Index.

Because having preset the time/frequency resource for SPS transmitting between BS and UE, BS and UE are aware of when to send out It penetrates and receives for ' the not ACK/NACK feedback of the SPS ' of PDCCH.It therefore, is including binding for the SPS of particular UE In window, the TPC field of all PDCCH is can be used to be used for ARI purpose, without distinguishing between the PUCCH on PCell in BS It distinguishes.That is, including the SPS of not PDCCH during the transmitting that the ACK/NACK of the SPS only for not PDCCH is fed back All TPC fields can be used to be used for ARI purpose, without in PCell in the one or more PDCCH emitted in bundled window It is distinguished between multiple SCell.

In this case, emit about PUCCH and the ACK/NACK of the SPS of not PDCCH is fed back, the TPC word of PDCCH Section is not used in original purpose (UL transmission power control).However, the TPC value in PDCCH is for previous transmission power Opposite deviant, rather than absolute value, and even if UE does not update TPC value once or twice, also keep preset transmitting function Rate.Other than using the transmission power control method of the TPC field in PDCCH, the power control side of supplement is additionally provided Method.Moreover, the TPC of original purpose cannot be obtained by limiting UE when needing the not transmitting of the SPS of PDCCH in fdd mode Value.Therefore, even if operating described in the upper surface of present invention example in TDD and also not showing when not applying the TPC of original purpose Landing influences network performance.

It can choose according to the example of embodiment 7 when needing only to feed back the ACK/NACK of the SPS of not PDCCH Specific PUCCH format 1a/1b resource index indicated by PDCCH is activated by the SPS of the RRC set configured with using.That is, right In the ACK/NACK for being only used for the not SPS of PDCCH, it can execute and be operated using the fall-back mode of PUCCH format 1a/1b.

As another example, when a PDSCH's ' for needing that there is PDCCH for ' not the SPS ' of PDCCH and ' When ACK/NACK is fed back, as mentioned above the TPC field of all PDCCH in bundled window is used for ARI purpose, so can To select and use 3 resource rope of PUCCH formatization according to ARI value indicated by the TPC field of the PDCCH detected by one Draw.

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

Embodiment 8

Embodiment 8 is related to a kind of for always executing in fall-back mode for ' including ' the not SPS transmitting of PDCCH The method of the ACK/NACK of DL transmitting.

For this purpose, the PUCCH format of the not transmitting of the SPS of PDCCH can be used for " only " to UE instruction by RRC signaling 1a/1b resource index collection.PUCCH format 1a/1b money can be configured or can configured according to other schemes as shown in table 14 Source indexed set.It, can be by activating the TPC field in PDCCH is specified to use PUCCH resource in SPS when indicating SPS activation Which index of indexed set.

According to the example of embodiment 8, when needing for ' only ' not ACK/NACK feedback of the SPS of PDCCH, Ke Yixuan It selects and activates specific PUCCH format 1a/1b resource index indicated by PDCCH using the SPS of the set configured by RRC.That is, For the only not no ACK/NACK of the SPS of PDCCH, the fall-back mode using PUCCH format 1a/1b can be executed.Here, for The size of 1 or 2 bits can be had according to the quantity of code word by not having the ACK/NACK feedback of the SPS of PDCCH, and can be made With PUCCH format 1a or 1b.

As another example, it needs for ' the not SPS ' of the PDCCH and ' ACK/ of a PDSCH ' with PDCCH NACK feedback may be selected and used and activate specific PUCCH format indicated by PDCCH by the SPS of the set of RRC configuration 1a/1b resource index.That is, feeding back even for the ACK/NACK for including the not transmitting of the SPS of PDCCH, can execute makes With the fall-back mode of PUCCH format 1a/1b.Here, there is one of PDCCH according to for ' not the SPS ' of PDCCH and ' 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 generated about a code word when binding).

Hereinafter, by description when needs are for ' the not SPS ' of the PDCCH and ' ACK/ of a PDSCH ' with PDCCH Detailed example of the invention when NACK is fed back.

Embodiment 8-1

Embodiment 8-1 is related to when needs are for ' the not SPS ' of the PDCCH and ' ACK/ of a PDSCH ' with PDCCH NACK feed back when using M=2,3 or 4 channel selection profile method.That is, for ' the SPS ' of PDCCH and ' not having The size of the ACK/NACK feedback payload of a PDSCH ' of PDCCH is 2 to 4 bits, and for no any loss Ground emits ACK/NACK feedback, can be using the channel selection side of 2,3 or 4 PUCCH format 1b (or PUCCH format 1a) Case.When using the channel selection profile for being used for PUCCH format 1b (or 1a) defined in the LTE version 8, this can be expressed To use the channel selection profile of LTE version 8 to operate under fall-back mode.

In multiple resources for channel selection, from ' the CCE index of the PDCCH ' corresponding to PDSCH obtains one PUCCH format 1b (or 1a) resource, and another PUCCH format can be indicated by being used to indicate the PDCCH of SPS activation 1b (or 1a).ACK/ can be emitted by the channel selection profile of one of two PUCCH format 1b (or 1a) resources of selection Nack message.

In addition, if needing further exist for PUCCH resource (for example, M=3 or 4), and by " corresponding to PDSCH's The corresponding PUCCH resource of value (CCE index+offset) that the CCE index of PDCCH " is obtained plus defined offset (for example, 1) It can be used for channel selection.Replace or supplement based on ' the other resource of the CCE index of the PDCCH ' corresponding to PDSCH, with lead to It crosses to defined offset (for example, 1) and adds the corresponding PUCCH of value obtained by the resource index that SPS activates PDCCH to assign Resource can be used for channel selection.

Alternatively, being similar to scheme above, following channel selection profiles can be applied, that is, use from ' not PDCCH SPS ' and ' the PUCCH format 1a/1b resource that the relevant information of a PDSCH ' with PDCCH explicitly or implicitly determines Index.

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

Because any one of three kinds of situations can be used to emit ACK/NACK information in UE, BS should be above Blind decoding is executed in the case of three kinds.

Embodiment 8-2

Embodiment 8-2 is related to a kind of when needing for ' the SPS ' of PDCCH and ' not having a PDSCH's ' of PDCCH When ACK/NACK is fed back, use space binding (that is, the ACK/NACK for multiple code words is bundled), using fixed in LTE version 8 The PUCCH format 1b (or 1a) of justice carrys out the method using fall-back mode.

Firstly, when ' not the SPS ' of PDCCH correspond to multiple (for example, 2) code words transmitting when, for its ACK/NACK response executes space binding.Similarly, when ' PDSCH ' with PDCCH corresponds to multiple (for example, 2) When the transmitting of code word, space binding is executed for the ACK/NACK response to it.If ' the SPS ' of PDCCH and ' do not had The only one of a PDSCH ' of PDCCH is a code word transmitting and the other is two code words emit, then only about two Code word transmitting bundlees to execute space.

Therefore, it makes comparisons with 2 to 4 bits when not executing space binding, when executing space binding, is used for The size of the ACK/NACK payload of the PDSCH ' of ' not the SPS ' of PDCCH and ' with PDCCH is reduced to 2 ratios It is special.

2 bit ACKs/NACK can be emitted by the PUCCH format 1b (or 1a) of traditional LTE version 8 to feed back.That is, if Space binding is executed, then the PUCCH format 1b (or 1a) of LTE version 8 can be used, and that ACK/NACK is operated under fall-back mode is anti- Feedback.

In such a case it is possible to select and use from one, ' the CCE rope of the PUCCH ' corresponding to PDSCH is extractive PUCCH format 1a/1b resource index.Swashed alternatively, may be selected and used by the SPS that the resource index configured in RRC is concentrated PUCCH format 1a/1b resource index indicated by PDCCH living.In other words, corresponding ACK/NACK response return back to PUCCH Format 1a, and be re-used by phase rotation, that is, one of two ACK/NACK responses are mapped to I channel, and another It is mapped to Q channel.Alternatively, two ACK/NACK responses return back to PUCCH format 1b and are re-used.

For example, in dibit ACK/NACK used in PUCCH format 1b used in LTE version 8, most significant bit (MSB) it can be mapped to for ' the not ACK/NACK of the SPS ' of PDCCH, and least significant bit (LSB) (LSB) can be mapped To for ' the ACK/NACK of a PDSCH ' with PDCCH (for example, PDCCH with DAI=1).Alternatively, can more than The exemplary opposite mode in face maps multiple ACK/NACK.

As another embodiment, for ' the ACK/NACK of the SPS ' of PDCCH is not mapped to the I axis of QPSK constellation, And for ' ACK/NACK of a PDSCH ' with PDCCH (for example, PDCCH with DAI=1) can be mapped to The Q axis of QPSK constellation.Alternatively, multiple ACK/NACK can be mapped in the mode opposite with above example.In addition, according to institute Received timing, for ' the not SPS ' of PDCCH and ' the ACK/NACK quilt received first of a PDSCH ' with PDCCH It is mapped to I axis, also, Q axis can be mapped to for received ACK/NACK later.Alternatively, can be to show with above Example opposite mode maps multiple ACK/NACK.

For example, when for ' not the ACK/NACK of the SPS ' of PDCCH be mapped to I axis and ' have PDCCH (for example, PDCCH with DAI=1) a PDSCH ' when being mapped to Q axis, even if UE fails to detect PDCCH (that is, ' corresponding to The PDCCH ' of PDSCH), then BS can receive the ACK/NACK response at least SPS.This is because when UE fails to detect When PDCCH, when for ' constellation positions when the ACK/NACK of the SPS ' of PDCCH is not mapped segment number I axis are equal to when use PUCCH format 1a is emitted ' only ' using BPSK constellation (that is, I axis) for ' the not star when ACK/NACK of the SPS ' of PDCCH It sets at seat.

As another example, ' the 1,1' ' and ' 0 of QPSK constellation, 0 ' can be mapped to for ' not PDCCH The ACK/NACK of SPS ', and ' 0,1' ' and ' 1,0 ' can be mapped to for ' with PDCCH (for example, having DAI=1's PDCCH a PDSCH ' ACK/NACK).Alternatively, can be corresponding multiple to be mapped with the opposite mode of above example ACK/NACK。

It is MIMO mould that constellation mapping above, which can be applied equally to the emission mode wherein in each cell, The case where formula and other situations.Constellation mapping above can also be applied, and actually whether with application space binding is unrelated (that is, unrelated with the presence or absence of the transmitting of 2 code words).

In Application Example 8-2, it might even be possible to feed back application to the ACK/NACK of ' only ' for the SPS of not PDCCH Space binding.In this case, BS should execute blind decoding for following three kinds of situations: for the ACK/ for ' only ' SPS The region PUCCH format 1a/1b of NACK, a PDSCH ' for having PDCCH for ' not the SPS ' of PDCCH and ' 3 region of the region PUCCH format 1a/1b and PUCCH format of ACK/NACK.

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

Embodiment 8-3

Embodiment 8-3 is related to when needs are for ' the not SPS ' of the PDCCH and ' ACK/ of a PDSCH ' with PDCCH Application space binding (that is, the ACK/NACK for multiple code words is bundled) and the channel selection profile using M=2 when NACK is fed back Method.When using the channel selection profile for being used for PUCCH format 1b (or 1a) defined in the LTE version 8, this can be by It is expressed as operating using the fall-back mode of the channel selection profile of LTE version 8.

Firstly, for ' not in the case where the transmitting of multiple (for example, two) code words of the SPS ' of PDCCH, for right Its ACK/NACK response executes space binding.Similarly, for ' with PDCCH a PDSCH ' it is multiple (for example, Two) in the case where the transmitting of code word, space binding is executed for the ACK/NACK response to it.If ' not PDCCH SPS ' and ' with one of PDCCH PDSCH's ' first is that a code word and the other is two code words, then only for two codes The transmitting of word executes space binding.

Therefore, the ACK/NACK payload of a PDSCH ' for ' not the SPS ' of PDCCH and ' with PDCCH Size by from when do not execute space bundle when 2 bits to 4 bits be reduced to when execute space bundle when 2 bits.

2 bit ACKs/NACK feedback can be emitted by the PUCCH format 1b (or 1a) of traditional LTE version 8.Here, It can be used using the channel selection profile of the M=2 of PUCCH1b (/ 1a).I.e., it is possible to returning using PUCCH format 1b (1a) Mode is moved back to emit 2 bit ACKs as the result for executing space binding/NACK feedback.

Here, M=2 can indicate two kinds of ACK/NACK information (2 bit ACKs/NACK letter for bundling result as space Breath) transmitting, or can indicate the channel selection using two PUCCH resources.Therefore, can be come by using channel selection Improve the detection performance of BS.

In two PUCCH resources for channel selection, the first PUCCH resource, which can be used, activates PDCCH by SPS Specified PUCCH format 1a/1b resource index, and the second PUCCH resource can be used from ' the PDCCH ' corresponding to PDSCH The extractive PUCCH format 1a/1b resource index of CCE rope.With above example on the contrary, the first and second PUCCH resources can To be respectively mapped to the PUCCH resource index for activating PDCCH specified by SPS and from ' PDCCH's ' corresponding to PDSCH The extractive PUCCH resource index of CCE rope.It can be selected by the channel of one of two PUCCH format 1b (or 1a) resources of selection Scheme is selected to emit ACK/NACK information.

It in the present embodiment, can be configured for example as shown in table 5 or table 8 in ACK/NACK information and PUCCH resource Between channel selection mapping relations.However, this is merely exemplary, and it can define and be mapped using new channel selection Relationship.

Example as the embodiment, it is assumed that provide the channel mapping relations using PUCCH format 1b as shown in table 5. Mapped for channel two PUCCH resources (With) in, it is provided by the PUCCH that SPS activates PDCCH specified Source can be mapped toAlso, from ' the extractive PUCCH resource of CCE rope of the PDCCH ' corresponding to PDSCH can be with It is mapped toCan determine such mapping configuration, and with ' the not SPS ' of PDCCH and ' corresponding to PDCCH's The reception sequence (receiving time) of PDSCH ' is unrelated.For example, even if when specific UE is losing PDCCH (i.e..' correspond to PDSCH PDCCH ') and only receive when emitting response after SPS, UE, which also can receive, at least rings the ACK/NACK of the SPS It answers.This is because when UE fails to detect PDCCH, for for ' the ACK/NACK of the SPS ' of PDCCH does not emit PUCCH resourceWith the PUCCH resource for ' only ' for the ACK/NACK transmitting of the SPS of not PDCCHIt is identical.Meanwhile the modified example as this embodiment, it can be mapped on the contrary with above example or can be with Corresponding PUCCH resource and DL emission type (PUCCH or SPS) are mapped according to the sequence of receiving time.

It, can will be in the channel mapping relations using PUCCH format 1b as another example of the present embodiment The ACK/NACK of SPS is mapped to 2 bit ACKs/NACK MSB (that is, being mapped to the first bit for the ACK/NACK of SPS), Also, for ' ACK/NACK of a PDSCH ' with PDCCH (for example, PDCCH with DAI=1) can be mapped to LSB (that is, the second bit is mapped to for the ACK/NACK of the PDSCH with PDCCH).Alternatively, even if when for SPS's ACK/NACK is mapped to I axis and for ' PDSCH's ' with PDCCH (for example, PDCCH with DAI=1) UE fails to detect PDCCH (that is, ' PDCCH ' corresponding to PDSCH) when ACK/NACK is mapped to Q axis, and BS also can receive To the ACK/NACK response emitted at least SPS.This is because working as in the case where PUCCH is detected and failed for ' not having The constellation positions when ACK/NACK of the SPS ' of PDCCH is mapped to I axis use PUCCH format 1a to use BPSK constellation with UE is worked as (that is, I axis) come emit for ' only ' not the SPS of PDCCH ACK/NACK response when constellation positions it is identical.Alternatively, can be with Configure mapping relations opposite with above example, and can the sequence of time based on the received execute mapping.

At least the ACK/NACK of SPS is responded in order to guarantee that BS is received, can feed back and emit in various ACK/NACK In the case of specific information is mapped to specific PUCCH resource.For example, can be made with configurating channel Choose for user relationship for The PUCCH resource and emit the PUCCH money for the ACK/NACK of ' only ' SPS thereon that the ACK/NACK of SPS transmitting is mapped to Source is identical.

Following table 15 shows modulation symbol (or the star for PUCCH format 1a and 1b in traditional LTE version 8/9 Seat).

[table 15]

In table 15, it is assumed that the value ' 0 ' of b (0) is NACK and ' 1 ' is ACK.So, the value ' 00 ' of (0) b, b (1) indicates ACK/ACK, and ' 11 ' indicate NACK/NACK.In this case, at least one preceding bit b (0) have in PUCCH Identical modulation symbol in format 1a and 1b.In other words, b (0) is when d (0)=1 in both two PUCCH formats 1a and 1b In always 0, and when d (0)=- 1 always 1 in both two PUCCH formats 1a and 1b.Therefore, BS can receive and examine The information about at least one preceding bit b (0) is surveyed, even if BS is not known whether using PUCCH format 1a or PUCCH format 1b received ACK/NACK feedback to emit.It can be with configurating channel Choose for user relationship, so that for ' not PDCCH The ACK/NACK of SPS ' uses the PUCCH resource for being mapped to a previous Bit b (0).Therefore, BS can guarantee at least for The reception of the ACK/NACK of SPS.

For example, it is interior as M=2, the channel selection mapping relations shown in following table 16 can be used.

[table 16]

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

For example, it is assumed that only receiving the SPS with a code word, and ' the PDSCH ' with PDCCH is not received.? In this case, PUCCH format 1a can be used to emit the ACK/NACK response for SPS.

Meanwhile ' when there is the PDSCH ' of PDCCH, channel choosing according to the present invention can be used when receiving together with SPS It selects.In this case, it is activated indicated by PDCCH by being concentrated through SPS in the PUCCH resource of the higher level configuration for SPS PUCCH resource be used as table 16In addition, from ' the CCE index of the PDCCH ' corresponding to PDSCH (passes through Pre-defined rule is implicitly) PUCCH resource that obtains is used as table 16In this case, BS should can connect It receives and the ACK/NACK of SPS is responded, and whether lose that ' PDCCH ' corresponding to PDSCH is unrelated with UE.

As described above, being used if UE transmitting responds the ACK/NACK of SPSHere, ACK corresponds to The wherein modulation symbol of b (0)=1 and d (0)=- 1, and NACK corresponds to the modulation symbol of wherein b (0)=0 and d (0)=1 Number.Meanwhile when UE transmitting ' when the ACK/NACK of the PDSCH ' with PDCCH is responded, can confirm for SPS and in table 16 Emit the resource of the ACK/NACK response for SPS on it.It will now be described using in table 16The case where ' ACK, NACK/DTX ' and ' NACK, NACK/DTX '.' ACK, NACK/DTX ' corresponds to wherein b (0) b (1)=11 and d (0)=1 Modulation symbol, and ' NACK, NACK/DTX ' corresponds to modulation symbol of wherein b (0) b (1)=00 and d (0)=1.In short, In the transmitting of the ACK/NACK response only for SPS and for SPS and ' there is the ACK/NACK response of the PDSCH ' of PDCCH Emit in the two, is emitted by identical modulation symbol (that is, for d (0)=- 1 of ACK and for the d (0)=1 of NACK) It is usingACK/NACK transmitting in for SPS ACK/NACK respond.Therefore, BS can detectedOn signal when confirmation at least the ACK/NACK of SPS is responded, and whether had been received for SPS's with BS ACK/NACK response or for SPS and ' with PDCCH PDSCH ' ACK/NACK response it is unrelated.

Meanwhile in the case where the case where ' ACK, ACK ' in table 16 and ' NACK/DTX, ACK ', it can be used from ' right It should be in the extractive resource of CCE rope of the PDCCH ' of PDSCH, that is, useTo emit ACK/NACK response.It is receiving ?On signal when, BS, which can be confirmed, receives the PDSCH's ' for ' not the SPS ' of PDCCH and ' with PDCCH ACK/NACK response.

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

It is, for example, possible to use PUCCH format 1b ' only ' to ring for having the ACK/NACK of the SPS there are two code word to emit It answers.Meanwhile it ' when there is the PDSCH ' of PDCCH, can be used according to example according to the present invention empty when being received together with SPS Between bundle.In both above situation, the ACK/ for SPS is emitted by same channel (PUCCH resource) and modulation symbol Nack message.More specifically, (for example, logic product) is bundled by application space, the ACK/ACK of two code words for SPS, ACK/NACK, NACK/ACK and NACK/NACK become ACK, NACK, NACK and NACK.If emitted simultaneously for SPS and ' tool There is the ACK/NACK of the PDSCH ' of PDCCH to respond, then bundling result according to space for the ACK/NACK response of SPS becomes ACK Or NACK, and respond respectively with for only SP ACK/NACK response channel and modulation symbol ACK/NACK and NACK/NACK is identical.Therefore, signal is being detectedWhen, BS can be according to the previous signals (example for being at least used for SPS Such as, (0) b) whether it is ACK or NACK and is whether space bundlees as a result, and received with BS by ACK/NACK response confirmation To the ACK/NACK response for SPS or for SPS and ' have the ACK/NACK response of the PDSCH ' of PDCCH unrelated.

It is MIMO mould that constellation mapping above, which can be applied equally to the emission mode wherein in each cell, The case where formula and other situations.Constellation mapping can also be applied, and actually whether with application space binding is unrelated (that is, with being No there are the transmitting of 2 code words is unrelated).

In Application Example 8-3, it might even be possible to feed back transmitting to the ACK/NACK of ' only ' for the SPS of not PDCCH Application space binding.It makes comparisons with embodiment 8-1 or 8-2, which, which can be reduced, wherein should execute blind Detecting by BS The quantity in region.More specifically, the channel selection side in the channel selection profile defined in LTE version 8, for the M being worth greatly Case is made of the superset of the channel selection profile of the M for small value.For example, a previous Bit in the channel selection of M=2 The transmitting of (for example, b (0)) or only ACK/NACK have and use the 1 of PUCCH format 1a in the case where not applying channel selection The identical result of bit ACK/NACK transmitting.Therefore, when pass through for the ACK/NACK for ' only ' SPS SPS activate When PUCCH format 1a/1b resource index indicated by PDCCH is used as the first resource index for channel selection, Neng Gou Wherein use channel selection the case where and wherein do not use channel selection the case where between distinguish.In this case, detection pair It is automatic to detect ' only ' for SPS's in the ACK/NACK response of the PDSCH ' of ' not the SPS ' of PDCCH and ' with PDCCH ACK/NACK response.Therefore, BS can execute blind Detecting in two regions, which is used for for channel selection ACK/NACK in PUCCH format 1a/1b resource is detected and (is detected including the ACK/NACK of ' only ' for SPS) and is used for ACK/NACK detection in PUCCH format 3.

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

Embodiment 8-3-1

As described above, generating ACK/NACK response about three kinds of situations.Situation 1 is related to having corresponding PDCCH's PDSCH, situation 2 is related to being used to indicate the PDCCH of DL SPS release, and situation 3 is related to the PDSCH of no corresponding PDCCH. Situation 3 is also referred to as the ACK/NACK for SPS PDSCH.

In the explanation of this embodiment, for ' PDCCH ' instruction situation 1 or situation 2 of ACK/NACK response, ' SPS PDSCH ' indicates situation 3, and particular UE, which executes, to be received the DL of three kinds of situations above and execute ACK/ received for DL The operation of NACK is illustrated.The ACK/NACK response emitted in n-th of UL subframe has in the n-th-k subframe about above Relationship (wherein, k ∈ K, and K:{ k of three kinds of situations for the DL ACK/NACK response emitted₀,k₁,…k_M-1, and refer to Table 12).The explanation of ACK/NACK transmitting subframe position will be omitted below.

In this embodiment, in order to support the dynamic emission power as caused by TPC command without reducing performance, can make With the predefined channel selection profile (defined in LTE version 8 or version 10) for passing through PUCCH format 1a.

The case where wherein configuring a serving cell, is described first now.

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

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

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

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

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

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

If UE receives SPS PDSCH and another PDCCH with DL DAI=1, using passing 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 configures to determine the first PUCCH resource (for example, indicating by the ARI by SPS PDCCH in the resource set that RRC is configured Resource), and based on for corresponding PDCCH (that is, the wherein PDCCH of DL DAI=1) transmitting the first CCE number (or index) determines the second PUCCH resource.

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

Meanwhile the case where wherein configuring multiple serving cells will now be described.

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

It is ordered in the TPC that wherein only the 2 bit TPC fields on PCell in the PDCCH of DL DAI=1 are used for original purpose It enables.

The 2 bit TPC fields of every other one or more PDCCH on PCell and one or more SCell are used for The TPC command of original purpose.UE hypothesis is in all one or more PDCCH on PCell and one or more SCell, ARI It is worth identical.

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

If UE only receives SPS PDSCH and wherein another PDCCH of DL DAI=1 on PCell, using 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 configuration (for example, by activating resource indicated by the ARI of PDCCH as SPS in the resource set that RRC is configured (referring to table 14)) determine the first PUCCH resource, also, based on for corresponding PDCCH (that is, wherein DL DAI=1 The number (or index) of first 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 this embodiment, ' PDCCH ' instruction situation 1 relevant to ACK/NACK response or situation 2, and ' SPS PDSCH ' indicates situation 3, as described in example 8 above -3-1.Term ' PDSCH ' or ' tool with DAI=1 The PDSCH ' of DAI > 1 DL refer to by corresponding to PDSCH PDCCH indicated by DL DAI be 1 or be greater than 1.Below will Omit the explanation of ACK/NACK transmitting subframe position.

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

The case where wherein using the channel selection of the M=2 in LTE version 8, is described first now.

If UE only receives SPS PDSCH and PDSCH with DL DAI=1 and does not receive with DAI > 1 DL PDSCH, then UE is while bundling the application space PDSCH through the TDD channel selection of the M=2 in LTE version 8 To emit ACK/NACK.When using LTE version 8TDD channel selection, UE emits two ACK/NACK bits.Here, can make Channel selection mapping relations (for example, table 5 above to 7) in LTE version 8 and the channel selection in LTE version 10 One of mapping relations (for example, table 8 above to 11), and this can be determined by RRC configuration.

In application 8 channel selection of LTE version, by SPS PUCCH resource (that is, the resource set configured by higher level SPS activation PDCCH indicated by resource, referring to table 14) determineValue.In addition, HARQ-ACK (0) be for The ACK/NACK/DTX response of SPS PDSCH transmitting.This is to solve wherein UE loss and have the case where PDSCH of DAI=1 Ambiguity and can definitely emit for SPS transmitting ACK/NACK response.

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

Simultaneously, it may be considered that the case where wherein using PUCCH format 3.

If UE receives both SPS PDSCH and the PDSCH with DL DAI=1, UE be can be assumed with DL The TPC field of the PDCCH of DAI=1 is used for ARI purpose.Then, UE PUCCH format 3 can be used emit 2 bit ACKs/ NACK (in non-MIMO cell) or 3 bit ACKs/NACK (in MIMO cell).

In this case, because not applying ACK/NACK to bundle, it is possible to emit ACK/NACK bit, without ACK/ The loss of nack message.Meanwhile because there is no the TPC fields for original TPC command purpose (because having DL DAI=1 PDCCH TPC field be used for ARI purpose), it is possible that improperly execute PUCCH power control.

In view of the situation, propose following two methods come in CA for the resource of TDD PUCCH format 3 Distribution.

First method is the resource allocation reused in CA for FDD PUCCH format 3.In this case, exist One or more TPC fields on PCell can be used for original purpose, and one or more on one or more SCell A TPC field can be used for ARI purpose.If UE only receives PDSCH on PCell, can be used in LTE version 8 The ACK/NACK of definition is bundled.

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

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

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

For using ACK/NACK feedback of the PUCCH format 3 in TDD, defining mode 1 and mode 2.Mode 1 can prop up Hold the ACK/NACK payload size until 20 bits.If the quantity of indicated ACK/NACK bit is more than 20, make It is bundled with space.If the quantity of the ACK/NACK bit indicated in mode 1 less than 20, is not supported to bundle.Meanwhile mode 2 be the scheme that (binding in the time domain or the binding in the domain CC) is wherein bundled with space binding together application obscure portions.That is, In mode 2, if the quantity of indicated ACK/NACK bit is more than x, space binding is simultaneously executed with part binding.

When to ACK/NACK feedback of the PUCCH format 1b in TDD is used using channel selection, define mode a and Mode b.Mode a is the scheme for not supporting any binding when the quantity of indicated ACK/NACK bit is less than 4 wherein.Mode B is wherein to bundle (in the time domain when the quantity of indicated ACK/NACK bit is more than 4 with space binding together application obscure portions Binding or the binding in the domain CC) scheme.

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

Hereinafter, by describing when only there are the ACK/NACK binding methods and resource allocation methods when DL reception on PCell.

Embodiment 9

Embodiment 9 is related to the binding of space in mode 1.

Mode 1 for TDD can be supported until the independent ACK/NACK of 20 bits emits.However, if indicated The quantity of ACK/NACK bit is more than 20, then needs application space to bundle.Because uncertain feedback is only when application space binding Vertical ACK/NACK information, it is possible that reducing the efficiency of HARQ operation, and therefore, it is necessary to maximally emit individual ACK/ Nack message, without bundling.That is, space is bundled is in DL throughput performance to the simple application of all ACK/NACK bits It is undesirable.Moreover, because mode 1 is to emit the scheme of independent ACK/NACK feedback in the case where no change, It should minimally bundle application space.Therefore, it is necessary to execute space binding so that the quantity of ACK/NACK bit closest to 20 but It is less than 20.

It is explained below when the quantity of indicated ACK/NACK bit is more than 20 for execute space binding it is detailed Method.

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

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

When TDD configuration is not 9DL:1UL, (or highest index) is indexed with the last one to from logic indexes CC acts start, tool, and there are two (the N of the code word configured_{configuredDLsubframe}+N_{CW_SF}- 9) a application space CC binding.It can be with Finally to the binding of the application space PCell (i.e., it is possible to assigning minimum logic index to PCell).Here, N_{configuredDLsubframe} It is the quantity of wherein feeding back ACK/NACK DL subframe 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]

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

As second method, it may be considered that the space binding of (subframe one by one) as unit of subframe.It, can according to second method It is bundled 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 execute space binding, until want actual transmission ACK/NACK bit quantity 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 the CC of UE configuration shows the number of the ACK/NACK bit when application first or second method in following table 17 Amount.

[table 17]

First method can maximally support that the independent ACK/NACK for PCell emits relative to second method, and It can be easily expressed.If the quantity of indicated ACK/NACK bit is more than 20, it is preferably, executes to CC one by one Space bundlees (that is, using first method).

Embodiment 10

In embodiment 10, the detailed applications example of above-mentioned mode 2 and mode b is described.Mode 2 is wherein and for making With the space binding of ACK/NACK feedback of the PUCCH format 3 in TDD together application obscure portions binding (binding in the time domain or Binding in the domain CC) scheme.Mode b is wherein when in the case where the quantity of indicated ACK/NACK bit is more than 4 Using when channel selection and for using the space of ACK/NACK feedback of the PUCCH format 1b in TDD to bundle application section together Divide the scheme of binding (binding in the time domain or the binding in the domain CC).

Mode 2 can valuably be used to improve the ACK/NACK performance of the UE about power limited.It is straight when that will support To 10 bits ACK/NACK FDD with support that TDD has more than FDD until when the TDD of ACK/NACK of 20 bits makes comparisons Small UL covering.In addition, mode 1 is (wherein, when indicated when the quantity of the DL CC in TDD 9DL-1UL configuration is more than 2 When the quantity of ACK/NACK bit is more than 20 application space bundle, and when indicated ACK/NACK bit quantity be 20 or Application space does not bundle when less) ACK/NACK cannot be supported to feed back.For example, in order to support on 5 DL CC and in TDD ACK/NACK feedback in 9DL-1UL configuration, needs 45 ACK/NACK bits in total, even if application space bundlees.Therefore, it is ACK/NACK feedback is at least supported in TDD 9DL-1UL configuration, needs support the above-mentioned mode 2 for PUCCH format 3.

Hereinafter, will be described in bundling to the space that mode 2 and mode b are applied.

Embodiment 10-1

In embodiment 10-1, space binding in the time domain is described.Other than the binding of space, it can also execute Time domain binding in this embodiment.

Can execute as space binding time domain binding, without in addition modify on each CC in LTE version 8 2 bit DAI of definition.Moreover, can simply be bundled using time domain on each CC in application time domain binding, without It must consider various forms of CA.That is, determining that the time domain binding method of the various situations for CA is that it is enough.Because being tied as time domain The size for the ACK/NACK information bit using 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 be used for ACK/NACK transmitting.

PDCCH about all distribution sequentially increases DAI value.Therefore, when using DAI, UE cannot be identified to be tied in time domain Tie up the case where the last one PDCCH is lost in window.In order to solve this problem, for finally detecting on each CC The DAI value of PDCCH can be input into ACK/NACK mapper, and then be 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 binding.

In the first CC of Figure 40, UE has been received PDCCH with DAI=0 in the first subframe and second The PDCCH with DAI=1 in subframe, but the PDCCH with DAI=2 in third subframe is received not yet.So Afterwards, because UE does not know whether to have transmitted the last one PDCCH (DAI=2), UE can be identified and be had been received All PDCCH in time domain bundled window.In addition, Figure 40 shows following situations, wherein be successfully decoded (that is, ACK) by connecing Each of the PDSCH of the PDCCH scheduling of receipts, and as a result, generate ACK/NACK information of the ACK as binding.With institute Together, UE can encode last received DAI value to the ACK information of generation, that is, DAI=1.UE coding and transmitting ACK and DAI (DAI=1), and then, BS can identify that UE has lost PDCCH (DAI=2).

The time domain bundling operation on the 2nd CC of Figure 40 is similar on the first CC.UE can will be last received DAI value (that is, DAI=0) encodes together with ACK information.Because UE encodes and emit ACK and DAI (DAI=0), BS can be with Identification UE has lost PDCCH (DAI=1).

In the 3rd CC of Figure 40, UE receives the PDCCH (DAI=0) in the first subframe, and receives in third PDCCH (DAI=2) in subframe.Even if UE it is unidentified go out PDCCH (DAI=1) in the second subframe transmitting, UE can be with Identify that itself has lost PDCCH (DAI=1) because the DAI value of received PDCCH do not increase sequentially.Although Figure 40 shows Wherein be successfully decoded out (that is, ACK) by received PDCCH scheduling PDSCH each the case where, but UE may ACK/NACK information of the NACK as binding is generated, because having lost the transmitting of a PDCCH.

In the 4th CC of Figure 40, UE only receives PDCCH (DAI=0), and is dispatched being successfully decoded by PDCCH PDSCH when generate ACK information.Generated ACK information and last received DAI value (DAI=0) can be encoded together.

In the 5th CC of Figure 40, UE only receives the PDCCH with DAI=0.UE does not know in the 4th subframe Transmit the PDCCH with DAI=1.Figure 40 show wherein not successfully decoding (that is, NACK) pass through by the received PDCCH of UE Scheduled PDSCH.Therefore, UE can produce nack message.

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

The example of PUCCH format 3 as the application for mode 2 can be compiled being defined on channel as shown in table 18 The ACK/NACK state of each CC before code.

[table 18]

DAI value using the ACK/NACK state of table 18, with the last received PDCCH on each of Figure 40 CC The result of the ACK/NACK of binding encoded is expressed as follows together: ' 01 (DAI=1) ' on the first CC, in the 2nd CC On ' 01 (DAI=0) ', ' 11 (NACK) ' on the 3rd CC, on five CC of ' 00 (DAI=0) ' He on the 4th CC ' 11 (NACK) '.

The ACK/NACK for 5 CC before executing channel coding in the PUCCH format 3 that mode 2 is applied to has The polymerization for imitating load is ' 0100110011 '.

The principle of the present invention for above-mentioned mode 2 can be applied equally to mode b.Application for mode b, Channel selection mapping relations (mapping relations between PUCCH resource and ACK/NACK bit) and NACK/DAI can be defined on Relationship between value.

Therefore, when being bundled using time domain, each ACK/NACK response on each CC can be expressed as tying Tie up ACK/NACK information.

Embodiment 10-2

In embodiment 10-2, the binding of CC domain space is described.Other than the binding of space, it can execute in this implementation Time domain binding in example.

The domain CC binding in, it is preferred that use DAI as indicate in a subframe in the binding being made of multiple CC The indicator of the sum of the PDSCH (or corresponding PDCCH) dispatched in window, rather than use DAI as on each CC The stored counts device of the PDSCH (or corresponding PDCCH) dispatched in multiple subframes is as in conventional DAI.This is because When DAI indicates the sum of PDSCH (or PDCCH) of each subframe, it is not necessary to provide and be abandoned in time most for wherein UE The solution of the case where the latter PDCCH.

Then, UE can be equal to when the quantity for emitting generated ACK for the DL being successfully decoded in bundled window Emit ACK when the sum of PDSCH (or PDCCH) in bundled window, and otherwise, UE emits NACK (at this point, DTX is expressed as NACK)。

Hereinafter, will be described in the domain CC bundlees application to mode b and mode 2.

It is described with reference to Figure 41 the channel selection for bundling to the domain application CC mode b.

In this case, it generally assumes that and is closed using the channel selection mapping of LTE version 10 (for example, table 8 above to 11) System.

If, can using the ACK/NACK PUCCH resource for implicitly determining (that is, obtaining from the CCE index of PDCCH) To select to provide with the PUCCH of the PDCCH dynamic link for the scheduling on PCC (or PCell) first in each subframe Source.

If only dispatching PDSCH on PCC (or PCell) in more CC configuration, can apply in LTE version 8 ACK/NACK resource impact (for example, table 5 above to 7).I.e., it is possible to execute the operation of the fall-back mode in LTE version 8.

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

In the TDD 2DL:1UL configuration of Figure 41, in the first subframe because PDSCH it is 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 money can be used Source is come using channel selection operations.It is, for example, possible to use channel selection mapping relations as shown in table 8 to execute ACK/NACK Transmitting.

In TDD 3DL:1UL configuration, PDSCH is only dispatched on PCC in all subframes.In such a case it is possible to such as The upper execution fall-back mode operation.It is, for example, possible to use channel selection mapping relations as shown in Table 6 to pass through PUCCH format 1b executes ACK/NACK transmitting.

It, can because dispatching PDSCH on both PCC and SCC in the first subframe in TDD 4DL:1UL configuration To determine PUCCH resource based on the CCE index of the PDCCH for dispatching the PDSCH on PCC.Because PDSCH is in the second son It is scheduled and only scheduled on a cell (PCC or SCC) in the third and fourth subframe in frame, it is possible to be based on The CCE index of the PDCCH of corresponding PDSCH determines PUCCH resource.In this way it is possible to be provided using identified PUCCH Source executes channel selection operations.It is, for example, possible to use the channel selection mapping relations shown in table 10 to execute ACK/ NACK transmitting.

The example bundled to the application of mode 2 domain CC 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 be 2 (that is, It include most two CC in a bundled window).

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

In addition, not including PCell (or PCC) in bundled window.That is, only configuring bundled window for SCell (SCC). Bundled window can be applied with the ascending order of CC index.

As shown in Figure 42, the domain CC binding can gradually apply bundled window (being made of 2 CC), until ACK/NACK The quantity (quantity of the ACK/NACK bit after the binding of application space) of bit becomes 12 or less.

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

In 3DL:1UL configuration, because the quantity of the ACK/NACK bit after executing space binding is 15, configuration Bundled window.The quantity of ACK/NACK bit after the bundled window for being configured to two CC (SCC3 and SCC4) is 12, and And therefore, it is not reconfigured bundled window.

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

Therefore, when being bundled using the domain CC part, for the binding knot of all ACK/NACK bits in bundled window Fruit (for example, result of logic and operation) is launched as ACK/NACK information.DAI in PDCCH is indicated in a subframe In the sum of PDSCH dispatched on all CC.The largest amount for being used for the bundled window of PUCCH format 3 can be determined as 2 (that is, most two CC (or cell) can configure a bundled window).

Embodiment 11

Embodiment 11 is related to passing through when only receiving PDCCH/PDSCH on PCell (hereinafter referred to as only PCell reception) The ACK/NACK launching technique of PUCCH format 3.Particularly, the only PCell being described in detail in TDD is received.

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

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

If TPC field is for the ARI purpose on SCell, ACK/NACK resource may be in only PCell reception condition It is lower fuzzy.In order to solve this problem, the multiplexing of the ACK/NACK defined in LTE version 8TDD system or ACK/NACK can be applied Binding.However, some ACK/NACK information cannot be emitted, and therefore if bundled using ACK/NACK binding or time domain, There may be the considerable damages of DL handling capacity.Moreover, because carrying out lap ACK/NACK with ACK/NACK mapping relations State, there is no assurance that 4 bit ACKs/NACK ACK/NACK performance in LTE version 8TDD system.

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

Embodiment 11-1

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

Figure 43 is the exemplary figure used for illustrating 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 as ' 00 '.In the diagram example of Figure 43, SCell The DAI value of PDCCH be all configured as ' 00 '.If it is ' 00 ' that the DAI value of the PDCCH on SCell, which is configured identically, Then PDCCH DCI can also be dispatched in public search space with imperial edict.In terms of UE realization, predefined value ' 00 ' is used as Virtual CRC (that is, for error detection when DAI value is not ' 00 ').

As shown in Figure 43, the TPC field of the PDCCH (that is, PDCCH with DAI=00) distributed first on PCell TPC command for original purpose.Every other PDCCH (packet other than 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 Value having the same in PDCCH.

UE behavior in this case can be defined as foloows.

If there are the PDSCH of no corresponding PDCCH to emit (that is, only SPS PDSCH) on PCell,

If √ emits without other PDSCH,

● use LTE version 8PUCCH format 1a/1b.

√ otherwise,

● use PUCCH format 3.

Exceptionally, ARI will be used as in the TPC field in the PDCCH with DAI=' 00 '.

Otherwise

If √, which has the single PDSCH with DAI=' 00 ' on PCell or exists on PCell, is used to indicate DL The single PDSCH with DAI=' 00 ' of SPS release,

√ otherwise,

● use PUCCH format 3.

In explanation above, wherein corresponding to DL SPS the case where ' there are the PDSCH of no corresponding PDCCH transmittings ' PDSCH.Moreover, ' DAI field of the single PDSCH ' instruction in the PDCCH corresponding to PDSCH with DAI=' 00 ' is 00.

Embodiment 11-1 is suitable for including for the 9DL:1UL sub-frame configuration of TDD ACK/NACK feedback and for mode 1 With the time domain/domain CC binding all situations of mode 2.

The above embodiments 11-1 is aggregated as follows.

The resource of LTE version 8PUCCH format 1a/1b and PUCCH format 1a/1b are used in the following cases: (1) wherein On PCell exist ' without corresponding PDCCH single PDSCH ' the case where, (2) wherein only on PCell exist ' have pair The single PDSCH ' of the PDCCH answered and the case where the DAI value in PDCCH is 00, or (3) are wherein only deposited on PCell In ' the single PDCCH ' of instruction DL SPS release and the case where DAI value in PDCCH is 00.

LTE version 8PUCCH format 3 is used for the case where other than (1) above, (2) and (3) situation.

If there is no ' without the PDSCH (that is, DL SPS PDSCH) ' of corresponding PDCCH, under executing on PCell The operation in face.If exist on PCell ' the DAI value of PDSCH ' and PDCCH with corresponding PDCCH are 00, The TPC field of PDCCH is used for actual TPC command.If there is ' the DAI of the PDCCH ' and PDCCH of instruction DL SPS release Value is 00, then the TPC field of PDCCH is used for practical TPC command.In other cases, all TPC fields are used as ARI.

In other cases (that is, on PCell exist ' without corresponding PDCCH PDSCH (that is, DL SPS PDSCH) '), all TPC fields of PDCCH are used as ARI.

In addition, being used as all fields value having the same of ARI in PDCCH in the case where the upper surface of all.

Embodiment 13

Embodiment 13 is related to one kind according to whether there are SPS PDSCH to carry out the method using different TPC fields.

As described above, generating ACK/NACK response about three kinds of situations.Situation 1 is related to having corresponding PDCCH's PDSCH, situation 2 is related to indicating the PDCCH of DL SPS release, and situation 3 is related to the PDSCH of no corresponding PDCCH.Situation 3 also referred to as the ACK/NACK of SPS PDSCH.

In the explanation of the embodiment, situation 1 or situation 2 are indicated for ' PDCCH ' relevant to ACK/NACK response, ' SPS PDSCH ' indicates situation 3, and particular UE, which is executed, to be received and execute received for DL for the DL of three kinds of situations above The operation of ACK/NACK is illustrated.Emit in n-th of UL subframe ACK/NACK response have the n-th-k subframe (wherein, K ∈ K and K:{ k₀,k₁,…k_M-1, and referring to table 12) in the ACK/NACK of the DL transmitting of three kinds of situations above is responded Relationship.Hereinafter, the explanation that ACK/NACK transmitting subframe position will be omitted.

If emitting ACK/NACK from UE by various formats, the complexity that BS explains the blind decoding of ACK/NACK is increased Degree.In order to improve the performance in BS, such as complicated blind decoding, and in order to resource is efficiently used, can be used by compared with The PUCCH format of high level configuration.Hereinafter, will be described in depending on whether there are SPS PDSCH and use different TPC fields Method.

It, can be as follows by the use of (2 bit) TPC field determination when configuring a serving cell.When there are SPS When PDSCH, the TPC field in all PDCCH can be used as ARI, and UE can be assumed ARI value all It is identical in PDCCH.Meanwhile if there is no SPS PDSCH, then the TPC field of the PDCCH with DL DAI=1 can be used for Original TPC command, and the TPC field of the PDCCH with DAI > 1 DL is used as ARI.UE can be assumed with DL ARI value in all PDCCH of DAI > 1 is identical.

In addition, when configuring a serving cell, it can be as follows by the use of PUCCH format determination.If UE ' is only ' it connects SPS PDSCH is received, then LTE version 8PUCCH format 1a/1b can be used.Alternatively, if UE ' only ' receive with DL LTE version 8PUCCH format 1a/1b then can be used in the single PDCCH of DAI=1.It 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), the TDD PUCCH format 3 in CA Resource allocation can be identical as the resource allocation in single carrier wave (or non-CA).That is, being used for the resource allocation methods of PCell Method identical with the resource allocation methods in non-CA can be used.It in the case of a ca, can will be for multiple cells PUCCH resource distribution determination is as follows.

It, can be as follows by the use of TPC field determination if configuring more than one serving cell.When there are SPS When PDSCH, the TPC field of all PDCCH on PCell and one or more SCell can be used for ARI purpose, and UE can be assumed identical with the ARI value on all PDCCH on one or more SCell in PCell.Meanwhile if there is no SPS PDSCH, then only the TPC field of the PDCCH with DL DAI=1 on PCell can be used for original TPC command, And the TPC field of the every other PDCCH on PCell and one or more SCell can be used for ARI purpose.UE can be with It is assumed that identical with the ARI value on all PDCCH on one or more SCell in PCell.

If configuring more than one serving cell, the purposes of PUCCH format can be used as follows.If UE ' is only ' it connects SPS PDSCH is received, then LTE version 8PUCCH format 1a/1b can be used.Alternatively, if UE ' only ' receive with DL LTE version 8PUCCH format 1a/1b then can be used in the single PDCCH of DAI=1.It, can be by PUCCH lattice for other situations Formula 3 is used as the PUCCH format configured by higher level.

Embodiment 14

Embodiment 14 is related to PUCCH money in view of above-described embodiment, for TDD HARG ACK/NACK response transmitting Source distribution method.

In traditional 8/9 system of LTE version, because to the ACK/NACK hair for being more than regulation bit size (for example, 4 bits) It penetrates using ACK/NACK binding (space binding and/or time domain binding), so having produced the damage of independent ACK/NACK information It loses.In LTE version 10 (or LTE-A) system, PUCCH format 3 is designed to support the independent ACK/NACK until 20 bits The transmitting of information.In CA and/or TDD support system, because the case where wherein emitting the ACK/NACK of 20 bits or more can Can occur, so needing the method for effectively utilizing resource while emitting ACK/NACK information without loss.

Figure 45 is the exemplary figure of the invention used illustrated for the TPC field in PDCCH.In the example of Figure 45 In, ARI is information of the instruction for the resource of the PUCCH format 3 of ACK/NACK transmitting.Although there is DL on PCell The TPC field of the PDCCH of DAI=1 is used for original TPC command, but the TPC word of other PDCCH on PCell and SCell Section is used as ARI.UE can be assumed that the ARI value on PCell and SCell is identical.Therefore, even if only detecting an ARI, It can determine the resource of PUCCH format 3.

When TPC field is re-used as ARI, the precision of PUCCH power control may be decreased.However, because can lead to ARI information is crossed certainly to determine the resource of PUCCH format 3, so relative to the drop in the precision of PUCCH power control It is low, it the use of the transmitting of lossy ACK/NACK information that do not have of PUCCH format 3 may be preferred for whole system.

In the example of Figure 45, when UE success at least one PDCCH of detection including ARI, it can be used by ARI The PUCCH format 3 of instruction responds to emit ACK/NACK.However, if UE ' only ' detect not ARI PDCCH (that is, The PDCCH with DAI=1 on PCell), then UE cannot obtain ARI information, and not can determine that 3 resource of PUCCH format.? In this case, conventional form can be used, i.e. the PUCCH format 1a/1b of LTE version 8/9 emits ACK/ without information loss NACK response.

It is, therefore, possible to provide a kind of resource allocation methods, this method can emit without any loss at one or The ACK/NACK response of the DL transmitting (PDCCH and/or PDSCH) emitted in multiple DL subframes.In addition, because with CA or non-CA without It closes ground and determines PUCCH format and PUCCH resource in the same manner, so simply and the behaviour of BS and UE can clearly dictate Make.

Figure 46 is the overall flow figure for illustrating the various embodiments proposed in the present invention.In the example of Figure 46, logical It crosses under the premise of higher level configures PUCCH format 3 for UE and provides explanation.

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

If the result of step S4610 be it is yes, then follow the steps S4620.Because having DAI=1's on PCell The TPC field of PDCCH is used for original TPC command, so UE cannot obtain ARI when only receiving the PDCCH with DAI=1 Information.Therefore, UE does not use PUCCH format 3.PUCCH format 1a/1b can be used to emit ACK/NACK in UE.It can pass through The implicit money for mapping and (being indexed that is, passing through the extractive PUCCH resource of CCE rope from PDCCH) to determine PUCCH format 1a/1b Source.

Meanwhile if the result of step S4610 be it is no, then follow the steps S4630.In step S4630, UE determines whether The single PDSCH of the not PDCCH only on PCell has been received.

If the result of step S4630 be it is yes, then follow the steps S4640.Because UE receives PDCCH not yet, UE cannot obtain ARI information, and not use PUCCH format 3.PUCCH format 1a/1b can be used to emit ACK/ in UE NACK.Here, UE cannot be obtained from the extractive PUCCH resource of PDCCH CCE rope because receiving PDCCH not yet Index.Therefore, UE can be according to the information for including in SPS activation PDCCH (for example, by activating the TPC in PDCCH in SPS Field reuses indicated information) determine that PUCCH resource indexes.

If the result of step S4630 be it is no, then follow the steps S4650.In step S4650, UE determines whether Receive ' PDSCH ' and other ' the not PDSCH ' of PDCCH with DAI=1 only on PCell.

If the result of step S4650 be it is yes, then follow the steps S4660.Even if in this case, because cannot obtain ARI information, so UE replaces PUCCH format 3 using PUCCH format 1a/1b.Here, UE can pass through channel selection profile Emit ACK/NACK information, to prevent the loss of ACK/NACK information.Channel selection can be executed so that from A (=2 or 3) a 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 be it is no, then follow the steps S4670.In step S4670, UE can be determined Wherein DAI value is not whether the value of the ARI (that is, TPC field) of the PDCCH of 1 (that is, DAI > 1) is equal in one or more SCell On all PDCCH ARI (that is, TPC field) value.

If the result of step S4670 be it is yes, then follow the steps S4680.In this case, UE can be used is referred to by ARI 3 resource of PUCCH format shown emits ACK/NACK information.UE assumes that ARI value is identical in all PDCCH, and can be with Step S4680 is executed using the ARI value at least one PDCCH.

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

In short, ' PDSCH ', ' not PDSCH of PDCCH with PDCCH of ACK/NACK should be emitted it for UE (SPS-PDSCH) ' and ' SPS discharges PDCCH ', can define following UE behavior.However, the scope of the present invention is not limited thereto, And can the available combinations of various embodiments through the invention execute TDD HARQ ACK/NACK resource allocation and transmitting Operation.

Firstly, the operation of non-CA system can be identical as ' the only PCell is received ' operation in CA environment.That is, when for TDD HARQ ACK/NACK resource allocation and transmitting operation when UE configures a serving cell can configured with working as more than one Only the TDD HARQ ACK/NACK resource when receiving PDSCH and/or PDCCH on PCell is divided in the case where a serving cell Match and emit operation it is identical.It therefore, can be by the description of the operation on PCell hereinafter, when configuring only one serving cell Replace with operation on the serving cell.

If the DAI in PDCCH of the PCell corresponding to PDSCH is 1, TPC field for original power control mesh 's.If the DAI in the PDCCH corresponding to PDSCH, which is greater than 1, TPC field, is used as ARI.Corresponding on SCell TPC field in the PDCCH of all PDSCH is used as ARI.UE assumes that all ARI values are identical.

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

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

If only receiving PDSCH and SPS-PDSCH with DAI=1 on PCell, by using The channel selection profile of PUCCH format 1b emits to execute ACK/NACK.The quantity A of PUCCH resource for channel selection is 2 Or 3.

If receiving one or more PDSCH (PDCCH corresponding with PDSCH, with DAI > 1) with DAI > 1, It then uses by 3 resource of PUCCH format of ARI instruction and executes ACK/NACK transmitting.

If receiving one or more PDSCH on SCell, use by ARI instruction 3 resource of PUCCH format Lai Execute ACK/NACK transmitting.

Therefore, for only receiving in PCell or on PCell and one or more SCell and ' having PDCCH's PDSCH ', ' not the PDSCH (SPS-PDSCH) ' of PDCCH and ' SPS discharge all situations of one of PDCCH ', can not damage Correctly and effectively emit ACK/NACK information in the case where losing ACK/NACK information.

Embodiment 15

Embodiment 15 is related to the resource allocation methods for PUCCH format 3.One serving cell of configuration will be described first The case where and the case where configuring more than one serving cell, will be described later.

If being configured with a serving cell, PUCCH format 3 can be used, the channel selection of M=2 can be used, or PUCCH format 1a/1b can be used in person.

When using PUCCH format 3, if there are SPS PDSCH, UE can be assumed with DL in bundled window The TPC field of DAI=1 is also used for ARI purposes.Then, UE can determine 3 resource of PUCCH format and PUCCH can be used Format 3 emits ACK/NACK.

In the case where wherein using the channel selection of M=2, operations described below can be executed.

If UE receives SPS PDSCH and PDCCH only with DL DAI=1 and has DL DAI without receiving band > 1 PDCCH, then UE can be used M=2 channel selection and simultaneously for the PDSCH indicated by SPS PDSCH and have DL The application space ACK/NACK of the PDCCH of DAI=1 bundlees to emit ACK/NACK.In order to emit 2 bit ACKs/NACK, UE can To use the implicit resource of LTE version 8 to distribute (for example, table 5) rule or meet the mapping relations of LTE version 10 (for example, table 8)。

It is assumed that UE by emitting ACK/NACK according to the channel selection profile of the mapping relations of LTE version 8, exists SPS PDSCH and there is the case where PDCCH of DAI=1 and the case where there is only SPS PDSCH between, or there are SPS The case where PDSCH and PDCCH with DAI=1 and the case where there is only the PDCCH with DAI=1 between carry out difference may It is indefinite.

, to solve the problems, such as in this, it can pass through activation SPS PDSCH's using the resource allocation for channel selection The TPC field of PDCCH determinesAnd it is determined by CCE index corresponding with PDSCHIn addition, HARQ-ACK (0) can be mapped to the ACK/NACK/DTX response of the transmission to SPS PDSCH, and HARQ-ACK (1) can To be mapped to the ACK/NACK/DTX response of the transmission to the PDSCH with corresponding PDCCH.Then, when UE loss has To the ACK/ of SPS PDSCH (selected channel and the in the channel bit or constellation that emit) when the PDCCH of DAI=1 When NACK response can be with the PDCCH and PDSCH corresponding with the PDCCH with DAI=1 with DAI=1 be received as UE The ACK/NACK response to SPS PDSCH in the ACK/NACK response to SPS PDSCH is identical.That is, BS can be by solid The detection of provisioning response part (selected channel and the bit or constellation that emit in the channel) is correctly received to SPS The ACK/NACK of PDSCH is responded, and whether detects the PDCCH with DAI=1 but regardless of UE.

Next, when UE receives SPS PDSCH and the only PDCCH with DAI=1 and has DL DAI without receiving When > 1 one or more PDCCH, PUCCH format 1a/1b transmitting ACK/NACK is can be used in UE.

In this case, the first PUCCH resource indexesIt can be from PDCCH's corresponding with PDSCH It is exported in CCE index, or may be configured to provide using SPS PUCCH indicated by the TPC field as SPS activation PDCCH Source.When use space orthogonal resource transmitting diversity (SORTD), by by offset applications in PDCCH's corresponding with PDSCH CCE index the second PUCCH resource of export can be indexed from " CCE index+1 "Or it can be configured to make With the second PUCCH resource of SPS PUCCH resource.

Meanwhile more than one serving cell can be configured, following two methods can be applied.

As first method, the resource allocation for FDD PUCCH format 3 can be reused.In this case, One or more TPC fields of one or more PDCCH on PCell can be used for original TPC purpose, and one or One or more TPC fields on one or more PDCCH on multiple SCell can be used for ARI purpose.If UE only exists SPS PDSCH or PDCCH are received on PCell, then the binding of the ACK/NACK defined in LTE version 8 can be used.

As second method, the resource allocation for TDD PUCCH format 3 in non-CA can be reused.That is, working as In the absence of SPS PDSCH, only the TPC field of the PDCCH with DAI=1 on PCell can be used for original TPC Purpose, and the TPC field of all other PDCCH on PCell and SCell can be used for ARI purpose.On the other hand, If SPS PDSCH exists, all TPC fields on PCell and one or more SCell can also be used for AIR mesh 's.UE can be assumed all AIR value having the same.When UE only receives SPS PDSCH on PCell or has DL When the PDCCH of DAI=1, the PUCCH format 1a/1b defined in LTE version 8 can be used.When UE is only received on PCell When to SPS PDSCH and with the PDCCH of DL DAI=1, one or more PUCCH lattice defined in LTE version 8 are used The channel selecting method of formula 1a/1b can be used.

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

In previously described embodiments of the present invention 1 to 15, about for UE configure PUCCH format 3 in the state of with " tool Have the PDSCH " of corresponding PDCCH, " PDSCH (SPS PDSCH) without corresponding PDCCH " and CA, non-CA, with And only " DL SPS discharges PDCCH " in PCell reception condition describes the various examples of ACK/NACK transmission.

The UCI of UE transmitting includes ACK/NACK, SR, CSI etc..CSI may include RI, PMI (the first PMI and second PMI), CQI etc..In some cases, it is desirable to emit ACK/NACK information together with other UIC (SR or SCI), that is, In identical subframe.Here, the case where description wherein emits ACK/NACK, SR and CSI by PUCCH.That is, of the invention Range be not applied to wherein ACK/NACK, SR and the CSI to be incidentally launched on PUSCH the case where.

Hereinafter, it will description for UE configuration PUCCH format 3 in the state of when emit together with ACK/NACK SR or Person emits example of the invention when CSI together with ACK/NACK.In other words, it will be described below using suitable PUCCH The method that format emits ACK/NACK and SR or ACK/NACK and CSI (that is, the CSI in period) simultaneously.

Embodiment 16

Embodiment 16 is related to the transmission side when two ACK/NACK responses should be launched and at the same time SR is needed to transmit Method.

In this case, two ACK/NACK response can be response to SPSP PDSCH and to one The response of " PDSCH with corresponding PDCCH ".Alternatively, two ACK/NACK responses can be the sound to a SPS PDSCH It should be with the response to one " DL SPS discharges PDCCH ".In two responses, for example, " PDSCH with corresponding PDCCH " In or the DL DAI value of PDCCH in " DL SPS discharge PDCCH " can be 1.In addition, an ACK/NACK in the present invention Response can correspond to single ACK/NACK response group, also, therefore, and two ACK/NACK responses can indicate two ACK/ NACK response.

When needing while two ACK/NACK responses of transmitting are with SR, the present invention proposes to use PUCCH lattice by SR resource The ACK/NACK of the ACK/NACK response (an either ACK/NACK response group) of formula 1b and another binding response (or Another binding ACK/NACK response group) transmission.

In two ACK/NACK responses, it can be first carried out and transmit related sky with the DL of two code words (2 CW) Between bundle.For example, if one in two ACK/NACK response with a code word (1 CW) in relation to and two in it is another It is a related with 2 CW, then space binding only is executed for 2 CW.Because in the SPS PDSCH in LTE version 8/9 there is only 1 CW, so space binding cannot be executed to SPS PDSCH, and and if only if " corresponding with the PDCCH with DAI=1 PDSCH " or " the DL SPS with DAI=1 discharges PDCCH " can execute space binding when being configured as 2 CW.Then, Relative to 2,3 or 4 bits before space bundlees, ACK/NACK payload is reduced to 2 bits.In this way, when must Therefore space binding can be executed when wanting, and, 2 bit ACKs/NACK can be emitted by PUCCH format 1b (or 1a) and rung It answers.

At this moment, the PUCCH lattice that the first PUCCH resource for PUCCH format 1b (1a) can be used as SR transmission distribution The resource of formula 1.As necessary (using SORTD), the second PUCCH resource for PUCCH format 1b (1a) can To use the Secondary resource of the PUCCH format 1 for RS transmission distribution.Such PUCCH format and resource allocation can indicate phase The two ACK/NACK response answered return back to PUCCH format 1a and is re-used by phase rotation, that is, two ACK/NACK One in response is mapped to I channel and another is mapped to Q channel.Alternatively, such PUCCH format and resource point PUCCH format 1b is return back to that can indicate that two ACK/NACK are responded.

In other words, SR can be executed by using SR resource transmitting ACK/NACK information, and by SR resource Constellation mapping can emit for the ACK/NACK of " SPS PDSCH " and for " PDSCH corresponding with PDCCH " or " DL The ACK/NACK of SPS release PDCCH ".

For example, 2 bit ACKs used in the PUCCH format 1b defined in LTE version 8/NACK response in, MSB can be with Being mapped to can be mapped to for the ACK/NACK and LSB of " SPS PDSCH " for " with the PDCCH with DAI=1 Corresponding PDSCH " is used for the ACK/NACK with " the DL SPS of DAI=1 discharges PDCCH ".Alternatively, can be shown with above-mentioned Corresponding ACK/NACK response is mapped to MSB and LSB by the opposite mode of example.Be mapped 2 can be emitted by SR resource Bit ACK/nack message.

As another example, in QPSK constellation, the ACK/NACK for " SPS PDSCH " can be mapped to I axis, and And " PDSCH corresponding with the PDCCH with DAI=1 " or the ACK/ for " the DL SPS with DAI=1 discharges PDCCH " NACK can be mapped to Q axis.Alternatively, corresponding ACK/NACK response can be mapped in above-mentioned exemplary opposite mode I axis and Q axis.In addition, in the ACK/NACK for " SPS PDSCH " and for " corresponding with the PDCCH with DAI=1 In PDSCH " or the ACK/NACK of " SPS with DAI=1 discharges PDCCH ", according to time sequencing for being firstly received The ACK/NACK of channel can be mapped to I axis and the ACK/NACK of the channel for receiving later can be mapped to Q Axis.Alternatively, corresponding ACK/NACK response can be mapped to I axis and Q axis in above-mentioned exemplary opposite mode.It can pass through SR resource emits the 2 bit ACKs/nack message being mapped.

As another example, in QPSK constellation, ' 1,1 ' and ' 0,0 ' can be mapped to for " SPS PDSCH " ACK/NACK, and ' 0,1 ' and ' 1,0 ' can be mapped to " PDSCH corresponding with the PDCCH with DAI=1 " or " tool There is the DL SPS release PDCCH " of DAI=1.Alternatively, can be corresponding ACK/NACK to be rung with the opposite mode of above-mentioned example I axis and Q axis should be mapped to.2 bit ACKs/the nack message being mapped can be emitted by SR resource.

It can be in an identical manner using such as the ACK/ for the DL transmission in QPSK constellation in the examples described above The mapping of NACK, no matter whether the transmission mode (TM) of each cell is MIMO or whether space binding is actually applied.

It is minimized according to the binding of above-mentioned example, the ACK/NACK information emitted by SR resource, and to SPS The ACK/NACK response of PDDSCH can steadily be emitted.

In the examples described above, although assuming to emit two ACK/NACK responses, two ACK/ for ease of description The transmission method of NACK response can be extended and be applied to the transmission of more than two ACK/NACK response.That is, being more than two The response of a ACK/NACK can be designated as two virtual ACK/NACK response groups and can be by such as in above-mentioned example In QPSK constellation mapping be launched.For example, for " SPS PDSCH " ACK/NACK information can be mapped to I axis and Other ACK/NACK information are (that is, for " PDSCH corresponding with PDCCH " and/or the ACK/ of " DL SPS discharges PDCCH " Nack message) 1 bit ACK/nack message can be generated as by space binding and time domain binding and Q can be mapped to Axis.2 bit ACKs/the nack message being mapped can be emitted by SR resource.According to this example, because can distinguish for SPS The ACK/NACK information of PDSCH and the ACK/NACK information for others DL transmission, so can be improved for SPS PDSCH ACK/NACK detection performance.

Embodiment 16-1

When UE receives one " SPS PDSCH " in TDD and one " corresponding with the PDCCH with DAI=1 In the case where needing when PDSCH " or one " DL SPS discharges PDCCH " while emitting ACK/NACK and SR, SR can be passed through Resource emits ACK/NACK counter using PUCCH format 1b.

The transmission of ACK/NACK counter is referred in no transmitting each ACK/NACK response (or ACK/ of binding Nack message) in the case where generate the information of how many acknowledgement character response in all ACK/NACK responses and fed back.The number of acknowledgement character response Mesh (ACK counter information) can be mapped to QPSK constellation and then be launched.

For example, " 00 " can indicate that there is no ACK, and " 01 " can be indicated there are an acknowledgement character response in QPSK constellation, " 10 " can indicate that there are two acknowledgement character responses, and " 11 " can indicate that there are three acknowledgement character responses.Then, relative to 2 to 4 Bit, ACK/NACK transport payload are reduced to 2 bits.2 bits can be emitted by PUCCH format 1b (/ 1a) ACK/NACK information.

In this case, for PUCCH format 1b (/ 1a) the first PUCCH resource can be used for SR transmission and The resource of the PUCCH format 1 of distribution.As necessary (using SORTD), for PUCCH format 1b (/ 1a) the The Secondary resource for the PUCCH format 1 distributed for RS transmission can be used in two PUCCH resources.Such PUCCH format and resource Distribution can indicate to indicate that the corresponding bit of ACK/NACK counter return back to PUCCH format 1a and by phase rotation quilt Multiplexing, that is, one in the bit of instruction ACK/NACK counter information is mapped to I channel and another is mapped to Q Channel.Alternatively, such PUCCH format and resource allocation can indicate that two bits return back to PUCCH format 1b.I.e., it is possible to ACK/NACK information is emitted to execute SR by using SR resource, and can be emitted by the constellation mapping in SR resource ACK/NACK counter information.

Although the transmission of two ACK/NACK response, this hair has been described for ease of description in the examples described above Bright principle can be applied to the transmission of more than two ACK/NACK response.For example, for more than two ACK/NACK Response, ACK/NACK counter information can be repeatedly mapped to two bits.For example, in QPSK constellation, " 00 " can be with Instruction be not present ACK, " 01 " can indicate there are one perhaps four acknowledgement character responses " 10 " can indicate that there are 2 or 5 ACK Response, and " 11 " can indicate that there are 3 or 6 acknowledgement character responses.

Embodiment 17

In traditional 8 system of LTE version, PUCCH format 2/2a/2b is defined as emitting CSI (CQI/PMI/RI).In order to Emit ACK/NACK and CSI simultaneously, PUCCH format 2a/2b can be used.Specifically, can by by modulated applications in PUCCH The R/S symbol of format 2a/2b emits ACK/NACK information.

For example, as shown in the following table 19, by about 1 bit (b (20)) or 2- bit (b (20), b (21)) ACK/ Nack message, which executes modulation, can be generated a modulation symbol (d (10)).

[table 19]

The modulation symbol (d (10)) being generated can be re-used during the generation of the RS sequence of PUCCH, and then make It is launched with PUCCH format 2a/2b.For details related with PUCCH format 2a/2b, 3GPP TS 36.211 can be referred to Chapters and sections 5.4.2.

In embodiment 17, describe in detail in the case of should emit two ACK/NACK response while emitting The method of ACK/NACK and CSI (that is, in identical subframe).It is assumed that while configuring ACK/NACK and CSI by higher level It transmits (that is, ACK/NACK and CSI simultaneous transmission parameter is arranged to TRUE)." ACK/NACK and CSI simultaneous transmission parameter is set The meaning for being set to TRUE " is emitted simultaneously in the case where no discarding CSI when ACK/NACK is transmitted with CSI transmission collision ACK/NACK and CSI.

Two ACK/NACK responses can be the response to one " SPS PDSCH " and " have corresponding PDCCH to one PDSCH " response.Alternatively, two ACK/NACK response can be response to one " SPS PDSCH " and to " a DL The response of SPS release PDCCH ".In these channels, " PDSCH with corresponding PDCCH " or " DL SPS release The DL DAI value that PDCCH in PDCCH " can have as 1.In the present invention, an ACK/NACK response can correspond to one A ACK/NACK response group.That is, two ACK/NACK responses also refer to two ACK/NACK response groups.

The invention proposes when needing that two ACK/NACK of transmitting response is with CSI simultaneously, by PUCCH format 2a (/ 2b) using as the RS modulation symbol shown in table 19 an ACK/NACK response (or an ACK/NACK response group) and The transmission of the ACK/NACK response (or ACK/NACK response group of a binding) of one binding.

In two ACK/NACK responses, it can be first carried out about the ACK/NACK response transmitted to 2-CW DL Space binding.For example, one in two ACK/NACK response be about 1 CW and the other is about 2 CW, can be only Space binding is executed about 2 CW.In LTE version 8/9, because not needed in SPS PDSCH there is only 1 CW To SPS PDSCH execute space binding and and if only if " PDSCH corresponding with the PDCCH with DAI=1 " or " have DAI= 1 DL PSS release PDCCH " can execute space binding when being made of 2 CW.Then, relative to before space bundlees 2,3 or 4 bits, ACK/NACK payload are reduced to 2 bits.Therefore, PUCCH lattice can be passed through as necessary Formula 2b (/ 2a) emits 2 bit ACKs/NACK response.

Such PUCCH format and resource allocation can indicate to be multiplexed by phase rotation using PUCCH format 2a corresponding Two ACK/NACK response, that is, one in two ACK/NACK response is mapped to I channel and another is mapped to Q channel.Alternatively, such PUCCH format and resource allocation can indicate that two ACK/NACK responses are multiplexed to PUCCH format 2b。

In other words, it can be emitted by the constellation mapping in the RS modulation symbol in PUCCH format 2b (/ 2a) and be used for " SPS The ACK/NACK of PDSCH " and the ACK/NACK for being used for " PDSCH corresponding with PDCCH " or " DL SPS discharges PDCCH ".

For example, MSB, which can be mapped to, is used for " SPS in 2 bits in the RS modulation symbol d (10) in table 19 The ACK/NACK of PDSCH ", and LSB can be mapped to for " PDSCH corresponding with the PDCCH with DAI=1 " or ACK/NACK for " the DL SPS with DAI=1 discharges PDCCH ".Alternatively, can be incited somebody to action in above-mentioned exemplary opposite mode Corresponding ACK/NACK response is mapped to MSB and LSB.In this way, 2 bit ACKs/nack message can be mapped to RS modulation symbol And it is launched by PUCCH format 2b (/ 2a).

As another example, in the QPSK constellation of the RS modulation symbol d (10) of table 19, for " SPS PDSCH " ACK/NACK can be mapped to I axis and " PDSCH corresponding with the PDCCH with DAI=1 " or for " have DAI= The ACK/NACK of 1 DL SPS release PDCCH " can be mapped to Q axis.Alternatively, can be in above-mentioned exemplary opposite mode Corresponding ACK/NACK response is mapped to I axis and Q axis.In addition, for " SPS PDSCH " ACK/NACK and for " with In the corresponding PDSCH " of PDCCH with the DAI=1 or ACK/NACK of " SPS with DAI=1 discharges PDCCH ", according to Time sequencing can be mapped to I axis and the channel for receiving later for the ACK/NACK for the channel being firstly received ACK/NACK can be mapped to Q axis.Alternatively, corresponding ACK/NACK can be responded in above-mentioned exemplary opposite mode It is mapped to I axis and Q axis.Therefore, 2 bit ACKs/nack message can be mapped to RS modulation symbol and pass through PUCCH format 2b (/ 2a) is launched.

As another example, in the QPSK constellation in the RS modulation symbol d (10) of table 19, ' 1,1 ' and ' 0,0 ' can be by Be mapped to the ACK/NACK for " SPS PDSCH ", and ' 0,1 ' and ' 1,0 ' can be mapped to " with DAI=1's The corresponding PDSCH " of the PDCCH or ACK/NACK of " the DL SPS with DAI=1 discharges PDCCH ".Alternatively, can with it is upper It states the opposite scheme of example and corresponding ACK/NACK response is mapped to I axis and Q axis.Therefore, 2 bit ACKs/nack message can be with It is mapped to RS modulation symbol and is launched by PUCCH format 2b (/ 2a).

As the mapping of the ACK/NACK for the DL transmission in QPSK constellation in the examples described above can be with identical Mode is applied, and whether TM but regardless of each cell is MIMO or whether space binding is actually applied.

It is minimized according to the binding of above-mentioned example, the ACK/NACK information emitted by CSI channel resource, and right The ACK/NACK response of SPS PDDSCH can steadily be emitted.

In the examples described above, although assuming to emit two ACK/NACK responses, two ACK/ for ease of description The transmission method of NACK response can be applied to the transmission of more than two ACK/NACK response.That is, more than two ACK/ The response of NACK can be designated as two virtual ACK/NACK response groups, and can pass through QPSK such as in the examples described above Constellation mapping is launched.For example, the ACK/NACK information for " SPS PDSCH " can be mapped to I axis and others ACK/NACK information (that is, for " PDSCH corresponding with PDCCH " and/or the ACK/NACK information of " DL SPS discharges PDCCH ") It can be bundled by space and time domain binding is generated as 1 bit ACK/nack message and can be mapped to Q axis.Therefore, 2 Bit ACK/nack message can be mapped to RS modulation symbol and is launched by PUCCH format 2b (/ 2a).According to originally showing Example, because the ACK/NACK information for SPS PDSCH and other ACK/NACK information for DL transmission can be distinguished, It can be improved the detection performance of the ACK/NACK for SPS PDSCH.

Embodiment 17-1

When UE receives one " SPS PDSCH " in TDD and one " corresponding with the PDCCH with DAI=1 PDSCH " or when " DL SPS discharge PDCCH ", needs to emit ACK/NACK and CSI simultaneously.ACK/ is being configured by higher level In the case where transmitting (ACK/NACK and CSI simultaneous transmission parameter=TRUE) while NACK and CSI, PUCCH lattice can be used Formula 2b (/ 2a) emits ACK/NACK as being used for while emitting the method for ACK/NACK and CSI (that is, in identical subframe) Counter.

The transmission of ACK/NACK counter refers to all in the case where each ACK/NACK of no transmitting is responded The information (or tied ACK/NACK information) how many acknowledgement character response are generated in ACK/NACK response is fed back.Acknowledgement character response Number (ACK counter information) can be mapped to such as the QPSK constellation of RS modulation symbol d (10) shown in table 19 and Then it is launched.

For example, ' 00 ' can indicate that there is no ACK, and ' 01 ' can indicate there are an acknowledgement character response in QPSK constellation, ' 10 ' can indicate that there are two acknowledgement character responses, and ' 11 ' can indicate that there are three acknowledgement character responses.Then, relative to 2 to 4 Bit (2 or 3 bits), ACK/NACK transport payload is reduced to 2 bits.Can by PUCCH format 2b (/ 2a) emit 2 bit ACKs/nack message.

Although the transmission of two ACK/NACK response, this hair has been described for ease of description in the examples described above Bright principle can be applied to the transmission of more than two ACK/NACK response.For example, being used for more than two ACK/NACK The ACK/NACK counter information of response can be repeatedly mapped to two bits.For example, ' 00 ' on QPSK constellation can be with Instruction be not present ACK, ' 01 ' can indicate there are one perhaps four acknowledgement character responses ' 10 ' can indicate that there are 2 or 5 ACK Response, and ' 11 ' can indicate that there are 3 or 6 acknowledgement character responses.

Embodiment 18

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

First, it is assumed that PUCCH format 3 is substantially used for ACK/NACK feedback in the FDD system of CA configuration.It also assumes that TPC field in the PDCCH for the PDSCH emitted on PCell or in the PDCCH discharged for DL SPS by with In original TPC command, and the TPC field in the one or more PDCCH emitted on one or more SCell is used for ARI purpose.

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

If PDSCH transmission is not present on SCell, the resource and ACK/NACK of PUCCH format 1a/1b can be used Mapping ruler.Specifically, if do not deposited on PCell in the case of PDCCH corresponding with PDSCH is not present on SCell In PDCCH and PDSCH, then because there is no DL transmission (that is, DTX), PUCCH format 1a/1b is not launched.Meanwhile If on SCell be not present PDCCH corresponding with PDSCH in the case of on PCell there are PDSCH (SPS PDSCH or Person PDSCH corresponding with PDCCH) or there is the PDCCH for indicating DL SPS release on PCell, then it can pass through PUCCH Format 1a/1b emits ACK/NACK.

When it is assumed that above-mentioned ACK/NACK transmission operates, it should emit in the subframe for wherein configuring SR transmission by higher level Operations described below can be executed in the case where ACK/NACK.

If in the case of PDCCH corresponding with PDSCH is not present on SCell on PCell there is no PDCCH and PDSCH, then because there is no DL transmission (that is, DTX), PUCCH format 1a/1b is not launched.In this case, Emit positive/negative SR by on-off keying (OOK) scheme.That is, the transmission about SR resource corresponds to positive SR and about SR resource It is non-transmitting correspond to negative SR.

If there are PDSCH (SPS on PCell in the case of PDCCH corresponding with PDSCH is not present on SCell PDSCH or PDSCH corresponding with PDCCH) or there is the PDCCH for indicating DL SPS release on PCell, then it can lead to It crosses and emits ACK/NACK information using PUCCH format 1a/1b in SR resource to emit SR and ACK/NACK information.Specifically, In the case where positive SR, ACK/NACK information is emitted in SR PUCCH resource, and in the case where negative SR, it can be in ACK/ Emit ACK/NACK information in NACK PUCCH resource.

Next, transmission while ACK/NACK and CSI will be described.In this embodiment it is assumed that being matched by higher level Transmission while setting ACK/NACK and CSI.

If in the case of PDCCH corresponding with PDSCH is not present on SCell on PCell there is no PDCCH and PDSCH, then because there is no DL transmission (that is, DTX), PUCCH format 1a/1b is not launched.In this case, It can be with the CSI of transmit cycle in the case where no transmitting ACK/NACK information using a series of PUCCH format 2.

If there are PDSCH (SPS on PCell in the case of PDCCH corresponding with PDSCH is not present on SCell PDSCH or PDSCH corresponding with PDCCH) and there is the PDCCH for indicating DL SPS release on PCell, then it can make ACK/NACK information and CSI are multiplexed and emitted with a series of PUCCH format 2.Specifically, PUCCH format 2a/ can be passed through The RS modulation symbol of 2b emits ACK/NACK information.In addition, PUCCH format 2a/ can be used in the case where normal CP 2b emits CSI and ACK/NACK information, and in the case where the CP of extension, and PUCCH format 2 can be used and emit combined coding CSI.

Embodiment 19

In embodiment 19, describe in the TDD system that CA is configured transmitting for DL transmission ACK/NACK with And the method for another UCI (SR or CSI).Specifically, the case where DAI field that the present embodiment is related to PDCCH is used as ARI.

First, it is assumed that PUCCH format 3 is substantially used for ACK/NACK feedback in the FDD system of CA configuration.It also assumes that TPC field in the PDCCH for the PDSCH emitted on PCell is used for original TPC command, and is being used for DAI field in the PDCCH of the PDSCH emitted on PCell is used for ARI purpose.Further, it is assumed that in one or more The TPC field (or DAI field) of one or more PDCCH of the PDSCH emitted on SCell is used as ARI.

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

If there are at least one PDSCH or on PCell, there are at least one PDSCH, PUCCH on SCell Format 3 can be used for ACK/NACK feedback.

If PDSCH corresponding with PDCCH is not present on PCell and SCell, LTE version 8 can be used The resource and ACK/NACK mapping ruler of PUCCH format 1a/1b.Specifically, if on PCell and SCell there is no with SPS PDSCH is not present in the case of the corresponding PDCCH of PDSCH, then the transmission corresponding to DTX and PUCCH format 1a/1b does not have It is launched.

Meanwhile if in the case of PDSCH corresponding with PDCCH is not present on PCell and SCell on PCell There are SPS PDSCH, then can emit ACK/NACK by PUCCH format 1a/1b.

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

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

If PDSCH corresponding with PDCCH is not present on PCell and SCell and SPS PDSCH is also not present, Then correspond to DTX and being transmitted without for PUCCH format 1a/1b is launched.In this case, it can be held by OOK scheme Row SR transmission.

If PDSCH corresponding with PDCCH is not present on PCell and SCell and there are SPS on PCell PDSCH then can emit SR and ACK/ by emitting ACK/NACK information using PUCCH format 1a/1b in SR resource Nack message.

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

If there is no PDCCH corresponding with PDSCH and SPS PDSCH is not present on PCell and SCell, It is launched corresponding to DTX and being transmitted without for PUCCH format 1a/1b.In this case, it can be used a series of The CSI of 2 transmit cycle of PUCCH format.

If emitting there is no PDSCH corresponding with PDCCH and on PCell SPS on PCell and SCell PDSCH, then ACK/NACK information and CSI are re-used and emit.Specifically, in the case where normal CP, PUCCH can be used Format 2a/2b emits CSI and ACK/NACK information, and in the case where the CP of extension, and the transmitting of PUCCH format 2 can be used The CSI and ACK/NACK being jointly encoded.

Embodiment 20

In embodiment 20, description in the TDD system that CA is configured for emitting for the DL ACK/NACK transmitted and separately The method of one UCI (SR or CSI).Specifically, the case where TPC field that the present embodiment is related to wherein PDCCH is used as ARI.

In this embodiment it is assumed that the DAI field and TPC field of PDCCH are defined as foloows.

DAI field on PCell is used as the counter of the PDCCH on PCell.DAI field on SCell can by with Make one in following proposal.First scheme is that the PDCCH that the DAI field on SCell is used as on corresponding SCell is counted Device.Another program is that the DAI field on SCell is arranged to ' 00 ' and even to dispatch DCI in public search space.With regard to UE For implementation, predetermined value ' 00 ' is also used as virtual CRC.

Meanwhile TPC field (that is, PDCCH with DAI=' 00 ' or DAI=1) quilt distributed first on PCell For original TPC purpose.Other all PDCCH are (all on the PDCCH and SCell with DAI > 1 on PCell PDCCH) TPC field be used for ARI purpose.It is assumed that being transmitted on corresponding all PDCCH with a PUCCH ARI value is identical.

If there are PDSCH transmission and PDCCH corresponding with PDSCH transmission is not present on PCell, UE is as follows Ground operation.If there is no PDSCH transmission, then PUCCH format 1a/1b transmitting ACK/NACK can be used in UE.Meanwhile it if depositing In PDSCH transmission, then the transmitting of PUCCH format 3 ACK/NACK (exception, the TPC of the PDCCH with DAI=' 00 ' can be used in UE Field is used as ARI).

In other cases, if existing on PCell (has DAI=' 00 ' (or DAI=1) with PDCCH PDCCH) a corresponding PDSCH or if on PCell exist instruction DL SPS release a PDCCH (have DAI The PDCCH of=' 00 ' (or DAI=1)), then PUCCH format 1a/1b transmitting ACK/NACK can be used in UE.It in other words, can be with Emit ACK/NACK using PUCCH format 3.

In short, there are the PDSCH (SPS PDSCH) that one does not have corresponding PDCCH, only existing when on PCell There are a PDSCH with corresponding PDCCH (PDCCH with DAI=' 00 ' (or DAI=1)) on PCell, or The PDCCH that person only has instruction DL SPS release in the case where PDSCH is not present on SCell on PCell (has The PDCCH of DAI=' 00 ' (or DAI=1)) when, PUCCH format 1a/1b can be used.In other cases, can make With PUCCH format 3.Here, when, there is no when the PDSCH without corresponding PDCCH, there is DAI=' 00 ' on PCell The TPC field quilt of the PDCCH (PDCCH corresponding with PDSCH or the PDCCH of instruction DL SPS release) of (either DAI=1) TPC field for the order of TPC field and others PDCCH is used for ARI purpose.In other cases, all The TPC field of PDCCH is used for ARI purpose.UE assume with a PUCCH transmit in corresponding all PDCCH by with It is identical for making the value of the field of ARI.

If configuring SR transmission by higher level wherein in the state of executing ACK/NACK as described above transmission It needs to emit positive SR and ACK/NACK in subframe, then can execute operations described below.

When there is a PDSCH without corresponding PDCCH on PCell, only existing and having on PCell The corresponding PDSCH of the PDCCH of DAI=1 (perhaps DAI=' 00 ') only exists on PCell with DAI=1 A PDCCH of (or DAI=' 00 ') and instruction DL SPS release, and can be by using PUCCH lattice in SR resource Formula 1a/1b emits ACK/NACK information to emit SR and ACK/NACK information.

For example, if be configured to in above-mentioned only PCell reception condition sent out in identical frame in a tdd system Penetrate ACK/NACK information and SR, then UE can be used PUCCH format 1b by SR resource emit ACK/NACK counter.ACK/ NACK counter is the information of the number of the acknowledgement character response in the multiple ACK/NACK responses of instruction.For example, if ACK/NACK is counted Number device is expressed as 2 bits (b (0), b (1)), then ' 00 ' indicates that ACK is not present, and ' 01 ' indicates that there are an ACK to ring It answers, ' 10 ' indicate that there are two acknowledgement character responses, and ' 11 ' indicate that there are three acknowledgement character responses.Alternatively, if license counts ACK Device information is repeatedly mapped to 2 bits (b (0), b (1)), then ' 00 ' can indicate that there is no ACK, ' 01 ' can indicate exist One perhaps four acknowledgement character responses ' 10 ' can indicate there are 2 perhaps 4 acknowledgement character responses and ' 11 ' can indicate there are 3 or 6 acknowledgement character responses.On the other hand, negative SR is transmitted, UE emits ACK/NACK by ACK/NACK PUCCH resource and responds (example Such as, the ACK/NACK response of binding).

(that is, in addition to there is a PDSCH without corresponding PDCCH on PCell, only exist in other situations On PCell there are one with there is the corresponding PDSCH of the PDCCH of DAI=1 (perhaps DAI=' 00 ') or only in PCell The upper feelings existed except the case where there is DAI=1 (or DAI=' 00 ') and indicate a PDCCH of DL SPS release Condition), SR and ACK/NACK are jointly encoded and are multiplexed and emitted using PUCCH format 3.

If there is a PDSCH without corresponding PDCCH on PCell, only exists and have on PCell The corresponding PDSCH of the PDCCH of DAI=1 (perhaps DAI=' 00 ') only exists on PCell with DAI=1 (or DAI=' 00 ') and PDCCH for indicating DL SPS release then can be used a series of PUCCH format 2 and be multiplexed With transmitting ACK/NACK information and CSI.Specifically, ACK/ can be emitted by the RS modulation symbol of PUCCH format 2/2a/2b Nack message.In addition, PUCCH format 2a/2b transmitting CSI and ACK/NACK information can be used in the case where normal CP, And in the case where the CP of extension, CSI and ACK/NACK that PUCCH format 2 emits combined coding can be used.

For example, if be configured to in above-mentioned only PCell reception condition sent out in identical frame in a tdd system Penetrate ACK/NACK information and CSI (CQI/PMI/RI) and using a series of PUCCH format 2 execute ACK/NACK information and It is transmitted while CSI, then ACK/NACK counter information can be emitted by the RS modulation symbol of PUCCH format 2/2a/2b.Example Such as, it if ACK/NACK counter is expressed as 2 bits (b (0), b (1)), then ' 00 ' indicates that ACK is not present, ' 01 ' indicates Indicate that there are two acknowledgement character responses there are one or four acknowledgement character responses, ' 10 ', and ' 11 ' indicate that there are three acknowledgement character responses. Alternatively, then ' 00 ' can indicate not deposit if ACK counter information is repeatedly mapped to 2 bits (b (0), b (1)) by license In ACK, ' 01 ' can indicate there are 1 perhaps 4 acknowledgement character responses ' 10 ' can indicate that there are 2 or 5 acknowledgement character responses, and ' 11 ' can indicate that there are 3 or 6 acknowledgement character responses.In the case where normal CP, PUCCH format 2b and CSI mono- can be used Transmitting ACK/NACK counter information is played, and in the case where the CP of extension, PUCCH format 2 and mono- starting of CSI can be used Penetrate ACK/NACK counter information.
