In a radio communications system, user equipment (UE) receives information in downlink (DL) from base station (BS), and And transfer information to BS in uplink (UL).The information transmitted or received between BS and UE includes data and various controls Information, and according to the type/use for the information for being transmitted or receiving, there are various physical channels.

Fig. 1 shows the physical channel for third generation partner program (3GPP) long term evolution (LTE) system and use The view of the universal signal transmission method of the physical channel.

When UE powers on or when UE reenters cell, UE is executed such as synchronous with BS in step S101 Search of initial zone operates.For search of initial zone operate, UE can from BS receive primary synchronization channel (P-SCH) with it is auxiliary synchronous Channel (S-SCH), to execute information synchronous with BS's, and obtaining such as cell ID.Thereafter, UE can receive physics from BS Broadcast channel, and obtain the broadcast message in cell.Meanwhile UE can receive downlink in search of initial zone step Reference signal (DL RS), and confirm downlink channel status.

The UE for completing search of initial zone can receive physical downlink control channel (PDCCH) and opposite with PDCCH The physical down link sharing channel (PDSCH) answered, and more detailed system information is obtained in step s 102.

Thereafter, UE can execute random access procedure in step S103 to S106, in order to complete the access to eNB. For random access procedure, UE can transmit leading (S103) via Physical Random Access Channel (PRACH), and can respond In leading message (S104) is received via PDCCH and PDSCH corresponding with PDCCH.It, can in random access competition-based To execute the contention resolved of the reception (S106) of PDSCH including additional PRACH transmission (S105) and PDCCH and corresponding thereto Program.

Then the UE of execution above procedure can receive PDCCH/PDSCH (S107) and transmitting physical uplink is shared Channel (PUSCH)/physical downlink control channel (PUCCH) (S108) is passed as general uplink/downlink signal Defeated program.The control information that BS is transferred to from UE is collectively referred to as uplink control information (UCI).UCI includes the automatic weight of mixing Pass request-reply/negative response (HARQ ACK/NACK), scheduling request (SR), channel quality indicator (CQI), precompile square Battle array indicator (PMI), order designator (RI) etc..In the present specification, HARQ ACK/NACK be called for short HARQ-ACK or ACK/NACK(A/N).HARQ-ACK includes at least one in affirmative ACK (ACK), negative ACK (NACK), DTX and NACK/DTX It is a.Usually UCI is transmitted via PUCCH.However, at the same time in the case of transmission control information and business datum, it can be via PUSCH transmission UCI.According to network request/instruction UCI can be aperiodically transmitted via PUSCH.

Fig. 2 is the schematic diagram for the structure for showing radio frame.In cellular OFDM packet radio communication system, in subframe Uplink/downlink data packet transfer is executed in unit, and it includes multiple OFDM symbols to be by a subframe definition The scheduled duration.3GPP LTE standards support may be used on frequency division duplex (FDD) Class1 radio frame structure and can It is applied to 2 radio frame structure of type of time division duplex (TDD).

Fig. 2 (a) shows the structure of Class1 radio frame.Downlink radio frame includes 10 subframes, and a son Frame includes two time slots in the time domain.One subframe required time of transmission is referred to as Transmission Time Interval (TTI).For example, One subframe has 1 millisecond of length, and a time slot has 0.5 millisecond of length.One time slot includes more in the time domain A OFDM symbol and in a frequency domain include multiple resource blocks (RB).In 3GPP LTE systems, because making in the downlink With OFDMA, so OFDM symbol indicates a symbolic component.OFDM symbol is properly termed as SC-FDMA symbols or symbolic component. RB as resource allocation unit may include multiple continuous subcarriers in one time slot.

The quantity for the OFDM symbol for including in one time slot can change according to the configuration of cyclic prefix (CP).CP packets Include extension CP and normal CP.For example, if configuring OFDM symbol by normal CP, the OFDM for including in one time slot is accorded with Number quantity can be 7.If configuring OFDM symbol by extending CP, because the length of an OFDM symbol is increased, institute Quantity with the quantity for the OFDM symbol for including in one time slot less than OFDM symbol in the case of normal CP.It is extending In the case of CP, for example, the quantity for the OFDM symbol for including in one time slot can be 6.In the unstable feelings of channel status Under condition, the case where such as UE high-speed mobiles, extension CP can be used in order to be further reduced intersymbol interference.

Using normal CP, because a time slot includes seven OFDM symbols, a subframe includes 14 A OFDM symbol.Meanwhile most three the first OFDM symbols of each subframe can be assigned to physical down link control letter Road (PDCCH), and remaining OFDM symbol can be assigned to physical down link sharing channel (PDSCH).

Fig. 2 (b) shows the structure of 2 radio frame of type.2 radio frame of type includes two fields, and per half frame Including five subframes, down link pilot timeslot (DwPTS), protective time slot (GP) and uplink pilot time slot (UpPTS).In from these, a subframe includes two time slots.DwPTS is used for search of initial zone, synchronization or the letter of UE It assesses in road.Channel estimatings of the UpPTS for BS is synchronous with the transmission of the uplink of UE.GP be used to eliminate due in uplink The multipath of down link signal between downlink postpones the interference generated in the uplink.

The structure of radio frame is exemplary only, and can differently change the subframe for including in radio frame The quantity of quantity, the quantity for the time slot for including in subframe or the symbol for including in a slot.

Fig. 3 A show to transmit the view of the signal handler of uplink (UL) signal at UE.

The combination of CQI, PMI, RI and CQI and ACK/NACK can be transmitted by PUCCH format 2/2a/2b.It can answer It is compiled with Reed-Muller (RM) channel.

For example, in LTE system, the channel described below for UL CQI compiles.(20, A) RM code compilations are used to believe Road bit stream a₀, a₁, a₂, a₃..., a_A-1.Table 10 shows the basic sequence for (20, A) code.a₀| and a_A-1| it respectively represents Most significant bit (MSB) and least significant bit (LSB).In the case where extending CP, maximum information amount of bits is 11, in addition to Except the case where CQI and ACK/NACK are transmitted simultaneously.After bit stream is compiled into 20 bits using RM codes, Ke Yiying It is modulated with QPSK.Before QPSK modulation, the bit being compiled can be scrambled.

Multicarrier system or carrier aggregation system refer to for polymerize and using multiple carrier waves system for broadband It supports, multiple carrier wave has the bandwidth less than target bandwidth.For the backward compatibility with existing system, when with less than mesh When multiple carrier waves of the wide bandwidth of marker tape are polymerize, the bandwidth of the carrier wave being polymerize can be limited to be used in existing system Bandwidth.For example, existing LTE system can support the bandwidth of 1.4,3,5,10,15 and 20MHz, and from LTE system evolution The bandwidth supported by the bandwidth that LTE system is supported more than 20MHz can be used only in advanced LTE (LTE-A) system.Alternatively, No matter the bandwidth used in existing system, can define new bandwidth, to support CA.Multicarrier can be with CA and aggregated bandwidth Interchangeably use.CA includes continuous CA and discrete CA.

Figure 20 is the concept map of the management of downlink component carrier in BS, and Figure 21 is the uplink point in UE The concept map of the management of loading gage wave.For convenience of description, it is assumed that higher level is MAC layer in Figure 20 and Figure 21.

The concept map for the case where Figure 22 is a MAC layer management multicarrier in BS.Figure 23 is a MAC layer pipe in UE The concept map for the case where managing multicarrier.

With reference to figure 22 and Figure 23, a MAC layer management one or more frequency carrier is to execute transmission and reception.Because logical The frequency carrier for crossing a MAC layer management needs not be mutually continuous, so resource management is flexible.In Figure 22 and Figure 23 In, for convenience's sake, physics (PHY) layer means one-component carrier wave.One PHY layer necessarily means independent radio frequency (RF) equipment.In general, an independent RF equipment means a PHY layer, but the invention is not restricted to this.One RF equipment can be with Including several PHY layers.

The concept map for the case where Figure 24 is multiple MAC layer management multicarriers in BS.Figure 25 is multiple MAC layer pipes in UE Another concept map of the case where concept map for the case where managing multicarrier, Figure 26 is multiple MAC layer management multicarriers in BS, and Another concept map for the case where Figure 27 is multiple MAC layer management multicarriers in UE.

Other than the structure shown in Figure 22 and Figure 23, several MAC layers can control several carrier waves, such as Figure 24 to figure Shown in 27.

As shown in Figure 24 and Figure 25, each MAC layer can control each carrier wave correspondingly, and such as in Figure 26 Shown in Figure 27, each carrier wave can be controlled correspondingly relative to each MAC layer of some carrier waves, and relative to residue One MAC layer of carrier wave can control one or more carrier wave.

System includes multiple carrier waves of such as carrier wave to N number of carrier wave, and carrier wave can be continuous or non-company Continuous, no matter UL/DL.TDD system is configured to more (N) a carrier waves of management in DL and UL transmission.FDD system is configured to make It must be in the multiple carrier waves of the middle use of each of UL and DL.In the case of FDD system, asymmetric CA can be supported, in asymmetric CA In the quantity of the bandwidth of the quantity of carrier wave and/or carrier wave that polymerize in UL and DL be different.

When the quantity phase for the component carrier polymerizeing in UL and DL is meanwhile, it is capable to configure all component carriers, so that With existing system back compatible.However, the present invention is not excluded for not accounting for the component carrier of compatibility.

Hereinafter, for convenience of description, it is assumed that opposite with PDCCH when transmitting PDCCH by DL component carriers #0 The PDSCH answered is transmitted by DL component carriers #0.However, it is possible to be dispatched using cross carrier wave, and another DL points can be passed through Measure carrier-wave transmission PDSCH.Term " component carrier " may alternatively be another equivalent terms (for example, cell).

Figure 28 shows the scene of the wherein transmission uplink control information (UCI) in the wireless communication system for supporting CA. For convenience's sake, in this example, it is assumed that UCI is ACK/NACK (A/N).UCI may include control information channel state letter Cease (for example, CQI, PMI, RI etc.) or scheduling request information (for example, SR etc.).

Figure 28 is the schematic diagram for the asymmetric CA for showing that a wherein 5 DL CC and UL CC are linked.It can be passed from UCI Asymmetric CA is arranged in defeated visual angle.I.e., it is possible to be arranged differently than for the DL CC-UL CC links of UCI and for data DL CC-UL CC links.For convenience's sake, if it is assumed that a DL CC can transmit most two code words, then ULACK/ The number of NACK bits is at least two.In this case, it is received by 5 DL CC to be transmitted by a ULCC Data ACK/NACK, need the ACK/NACK of at least 10 bits.In order to support the DTX state of each DL CC, for ACK/ At least 12 bits (5^5=3125=11.61 bits) are needed for NACK transmission.Because can with existing PUCCH format 1a/1b To transmit the ACK/NACK of most 2 bits, so such structure is unable to the ACK/NACK information of transmitting extended.It rises for convenience See, although describing wherein since CA increases the example of UCI information content, due to the increase of antenna amount, TDD system and prolongs The presence of backhaul subframe etc. in slow system may increase UCI information content.It is similar to the situation of ACK/NACK, when passing through a UL When CC transmits control information associated with multiple DL CC, control information content to be transmitted increases.For example, that must pass through In the case of UL anchors (or main) CC transmission is for the CQI of multiple DL CC, CQI payload may be increased.

The main CC of DL can be defined as to the DL CC linked with the main CC of UL.Link includes that hiding link and display link. In LTE, a DL CC and a UL CC are inherently matched.For example, matched by LTE, it can with the main CC of the UL DL CC linked To be referred to as the main CC of DL.This may be considered that hiding link.Display link instruction network configured in advance links and passes through RRC etc. It is sent with signal.In display links, main DL CC can be referred to as with the DL CC of the main CC pairings of UL.UL master (or anchor) CC can be with It is the UL CC for transmitting PUCCH.Alternatively, the main CC of UL can be the UL CC by PUCCH or PUSCH transmission UCI.It can be by Higher level signaling configures the main CC of DL.The main CC of DL can be that UE executes the DL CC being initially accessed.DL CC other than the main CC of DL It can be referred to as UL auxiliary CC.Similarly, the UL CC other than the main CC of UL can be known as UL auxiliary CC.

LTE-A manages radio resource using the concept of cell.It is down-chain resource and upper by cell definitions The combination of downlink resources and uplink resource is not essential component.Therefore, cell can be only by downlink Resource is individually composed or can be combined by the group of down-chain resource and uplink resource.If CA is supported, under Link between downlink resources carrier frequency (or DL CC) and uplink resource carrier frequency (or UL CC) can be by System information indicates.It is properly termed as main plot (PCell) with the cell (or PCC) that basic frequency operates, and with secondary frequency The cell (or SCC) of (secondary frequency) operation is properly termed as secondary cell (SCell).It can be respectively by DL CC It is known as DL cells and UL cells with UL CC.Furthermore it is possible to which anchor (or main) DL CC and anchor (or main) UL CC are known as DL respectively PCell and UL PCell.PCell is used by UE execution initial connection establishment processing or connection re-establishes processing.PCell It can also indicate that the cell indicated in the switching process.SCell can be configured after executing RRC connections foundation, and can be with For providing additional radio resources.PCell and SCell may be collectively referred to as serving cell.Therefore, it is in RRC_ in UE In the case that CONNECTED states are without being configured with CA or not supporting CA, there is only a serving cell, the service is small Area only includes PCell.On the contrary, in the case where UE is in RRC_CONNECTED states and is configured with CA, there are one Or multiple serving cells and each serving cell include PCell and all SCell.For CA, in addition at connection foundation In reason except the PCell of initial configuration, network can be the UE configurations that CA is supported after starting initial safe activation processing One or more SCell.

DL-UL pairings can be only defined in fdd.Since TDD uses identical frequency, so DL-UL pairings cannot be defined. By UL E-UTRA absolute radio frequencies channel number (EARFCN) information of SIB2, DL-UL chains can be determined according to UL links It connects.For example, DL-UL links can be obtained by SIB2 decodings during initial access, and in other manners, pass through RRC Signaling can obtain DL-UL links.Therefore, there may be only SIB2 links, and do not define other DL-UL clearly and match It is right.For example, in the 5DL of Figure 28:In 1UL structures, DL CC#0 and UL CC#0 can have SIB2 linking relationships and remaining DL CC can have relationship with other UL CC for not being configured for UE.

In order to support the scene of such as Figure 28, new scheme is needed.Hereinafter, in the communication system for supporting carrier wave polymerization In for the PUCCH format (for example, multiple A/N bits) of the feedback of UCI be referred to as CA PUCCH formats (or PUCCH format 3).For example, PUCCH format 3 be used to transmit A/N corresponding with PDSCH (or PDCCH) for receiving in more DL serving cells Information (possibly, including DTX state).

Figure 29 A to Figure 29 F show the structure and signal handler of the PUCCH format 3 according to the present embodiment.

Figure 29 A show that the PUCCH format according to the present embodiment is applied to the feelings of the structure of PUCCH format 1 (normal CP) Condition.With reference to figure 29A, channel compile block to information bit a_0, a_1 ... and a_M-1 (for example, multiple ACK/NACK bits) is held Row channel compiles and generates compiling bit (bit being compiled or the bit compiled) (or code word) b_0, b_ And b_N-1 1 ....M indicates the size of information bit, and the size of N presentation code bits.Information bit includes UCI, example Such as, multiple ACK/NACK bits by multiple DL CC multiple data (or PDSCH) received are used for.No matter configuration information ratio Type/quantity/size of special UCI, information bit a_0, a_1 ... and a_M-1 are compiled by joint.For example, if information Bit includes multiple ACK/NACK data for multiple DL CC, then not relative to each DL CC or each ACK/NACK bits Channel compiling is executed, but channel compiling is executed relative to entire bit information.Therefore single codeword is generated.Channel compiling can be with Including but not limited to simple repetition, either simplex compiling, Reed-Muller (RM) compiling, punctured RM compilings, tail biting convolutional encoding (TBCC), low-density check (LDPC) and turbo compilings.Although it is not shown, but consider order of modulation and stock number, it can be to compiling Code bit executes rate-matched.Rate-matched function can be included in channel compiling block or can use independent functional block To execute.For example, channel compiling block can execute (32,0) RM compilings to obtain single codeword simultaneously relative to multiple control information And execute circular buffering rate-matched.

Bit b_0, b_1 ... and b_N-1 that modulators modulate is compiled, and generate modulation symbol c_0, c_ 1 ... and c_L-1.L indicates the size of modulation symbol.Tune is executed by changing amplitude and the phase of the signal being transmitted Method processed.For example, modulator approach includes n- phase-shift keying (PSK)s (n-PSK), (wherein n is greater than or equal to for n- quadrature amplitude modulations (QAM) 2 integer).More specifically, modulator approach may include binary system PSK (BPSK), orthogonal PSK (QPSK), 8-PSK, QAM, 16-QAM, 64-QAM etc..

Modulation symbol c_0, c_1 ... and c_L-1 are divided into time slot by divider.Modulation symbol is divided into time slot Sequence/pattern/method do not limit specifically.For example, modulation symbol is sequentially divided then by divider since header Gap (local type).In this case, as shown, can by modulation symbol c_0, c_1 ... and c_L/2-1 is divided into Time slot 0, and can by modulation symbol c_L/2, c_L/2+1 ... and c_L-1 is divided into time slot 1.When being divided into time slot When modulation symbol can be interleaved (or arrangement).For example, the modulation symbol of even-numbered can be divided into time slot 0 and can The modulation symbol of odd-numbered is divided into time slot 1.Modulation treatment can be changed and divide the sequence of processing.Replacement will be different Compiling bit be divided into time slot, identical compiling bit may be configured to repeat with time slot units.In this case, It can be omitted divider.

DFT pre compilers execute DFT precompiles (for example, 12 point DFT) relative to the modulation symbol for being divided into time slot, with Generate single carrier waveform.Refer to the attached drawing, can by be divided into time slot 0 modulation symbol c_0, c_1 ... and c_L/2-1DFT Prelist be translated into DFT symbols d_0, d_1 ... and d_L/2-1, and be divided into modulation symbol c_L/2, c_L/2 of time slot 1 + 1 ... and c_L-1 prelisted by DFT be translated into DFT symbols d_L/2, d_L/2+1 ... and d_L-1.DFT precompiles can be with It is replaced by another linear operation (for example, Walsh precompiles).DFT pre compilers can be replaced by CAZAC modulators. CAZAC modulators be divided into using corresponding sequence modulation time slot modulation symbol c_0, c_1 ... and c_L/2-1 and C_L/2, c_L/2+1 ... and c_L-1, and generate CAZAC modulation symbols d_0, d_1 ..., d_l/2-1 and d_L/2, d_ L/2+1 ... and d_L-1.For example, CAZAC modulators include CAZAC sequences or (CG) that is generated for LTE computers The sequence of 1RB.For example, if LTE CG sequences be r_0 ... and r_L/2-1, CAZAC modulation symbol can be d_n= C_n*r_n or d_n=conj (c_n) * r_n.

Extension blocks extension at SC-FDMA symbols horizontal (time domain) is subjected to the signal of DFT.It is executed using extended code (sequence) The time domain of SC-FDMA symbol levels extends.Extended code includes quasiorthogonal code and orthogonal code.Quasiorthogonal code may include still unlimited In pseudo noise (PN) code.Orthogonal code may include but be not limited to Walsh codes and DFT codes.Although for the ease of retouching for the present invention The representative example that orthogonal code is described as to extended code is stated, but orthogonal code is merely exemplary and may alternatively be accurate orthogonal Code.Extended code size (or spreading factor (SF)) is limited by being used for transmission the quantity for the SC-FDMA symbols for controlling information Maximum value.For example, in the case where four SC-FDMA symbols are used for transmission control information in one time slot, each (puppet) orthogonal code w0, w1, w2 and w3 with length 4 can be used in time slot.SF means the degree of expansion of control information, and And it is associated with the multiplexing order of the multiplexing order of UE or antenna.SF can become 1,2,3,4 ... according to the demand of system, and Either UE can be notified between BS and UE by DCI or RRC signaling by predefined.For example, for controlling information One of SC-FDMA symbols be punctured to transmit SRS in the case of, have reduced SF values (for example, SF=3 rather than SR= 4) extended code can be applied to the control information of time slot.

The signal generated by above procedure can be mapped to the subcarrier in PRB, be subjected to IFFT, and be converted into Time-domain signal.Time-domain signal is attached to CP and the SC-FDMA symbols generated are transmitted by the RF stages.

It is assumed that ACK/NACK of the transmission for 5 DL CC, will be described in detail each program.It can be passed in each DL CC By the number of the ACK/NACK bits including if can be 12 if DTX state in the case of defeated two PDSCH.Consider QPSK tune The time of system and SF=4 extend, and compiling block size (after rate matching) can be 48 bits.It can be by the bit tune of compiling 12 symbols in the QPSK symbols that 24 QPSK symbols are made, and are generated are divided into each time slot.In each time slot In, 12 QPSK symbols are converted into 12 DFT symbols by 12 point DFT operations.In each time slot, using having in the time domain There is the extended code of SF=4 by 12 DFT sign extendeds to four SC-FDMA symbols and maps.Because passing through [2 bit × 12 + 8 SC-FDMA symbols of a subcarrier] 12 bits of transmission, so compiler rate is 0.0625 (=12/192).SF=4's In the case of, it can be multiplexed up to four UE per PRB.

It is merely exemplary with reference to the figure 29A signal handlers described, and is mapped to the signal of PRB in Figure 29 A It can be obtained using various equivalent signal handlers.The signal of Figure 29 A will be equivalent to reference to figure 29B to Figure 29 F descriptions Processing routine.

Figure 29 B are sequentially different from Figure 29 A DFT pre compilers and extension blocks.In Figure 29 A, because extension blocks Function is equal to being multiplied for the DFT symbol sebolic addressings that are exported from DFT precompiles and the specific constant in SC-FDMA symbol levels, even if When the sequence of DFT precompiles and extension blocks changes, the value for being mapped to the signal of SC-FDMA symbols is identical.It therefore, can be with With channel compiling, modulation, divide, the sequence of extension and DFT precompiles executes the signal processing journey for PUCCH format 3 Sequence.In this case, division processing and extension process can be executed by a functional block.For example, modulation symbol can be with It is extended at the horizontal place of SC-FDMA symbols, while being alternatively divided into time slot.As another example, when by modulation symbol When being divided into time slot, modulation symbol can be replicated to be suitble to the size of extended code, and can be multiplied by modulation to correspond The element of symbol and extended code.Therefore, the modulation symbol sequence generated in each time slot is extended to horizontal in SC-FDMA symbols Multiple SC-FDMA symbols at place.Thereafter, complex symbol corresponding with each SC-FDMA symbols with SC-FDMA symbolic units into Row DFT precompiles.

Figure 29 C are sequentially different from Figure 29 A modulator and divider.It therefore, can be to combine at subframe level Channel is compiled and is divided and the sequence of modulation, DFT precompiles and extension is executed for PUCCH format at each time slot level 3 signal handler.

Figure 29 D are sequentially different from Figure 29 C DFT pre compilers and extension blocks.As described above, because the letter of extension blocks Number is equal to the specific constant that the DFT symbol sebolic addressings exported from DFT pre compilers are multiplied by from SC-FDMA symbol levels, so even if When the sequence of DFT precompiles and extension blocks is changed, the value for being mapped to the signal of SC-FDMA symbols is identical.Therefore, lead to Crossing at subframe level combined channel compiling and dividing and modulated at each time slot level can execute for PUCCH format 3 Signal handler.It is extended in the modulation symbol sequence that each time slot generates multiple at SC-FDMA symbol levels SC-FDMA symbols, and modulation symbol sequence corresponding with each SC-FDMA symbols carries out DFT with SC-FDMA symbolic units Precompile.In this case, modulation treatment and extension process can be executed by a functional block.For example, when modulating When the bit of coding, generated modulation symbol can be directly extended at the horizontal place of SC-FDMA symbols.As another example, when When modulating encoded bit, modulation symbol is replicated to be suitable for the size of extended code, and modulation symbol and extended code Element can be multiplied correspondingly.

Figure 29 E show that the case where being applied to the structure of PUCCH format 2 according to the PUCCH format 3 of the present embodiment is (normal CP), and Figure 29 F are shown (extension the case where being applied to the structure of PUCCH format 2 according to the PUCCH format 3 of the present embodiment CP).Baseband signal processing routine is equal to relative to those of Figure 29 A to Figure 29 D descriptions.Due to reusing existing LTE's The structure of PUCCH format 2, quantity/position of UCI SC-FDMA symbols and RSSC-FDMA symbols in PUCCH format 3 with The difference of Figure 29 A.

Table 14 shows the position of the RS SC-FDMA symbols in PUCCH format 3.It is assumed that in the case of normal CP in time slot SC-FDMA symbols quantity be 7 (index 0 to 6), and the number of the SC-FDMA symbols in the case where extending CP in time slot Amount is 6 (indexes 0 to 5).

Table 14

Here, RS can reuse the structure of existing LTE.It is, for example, possible to use the cyclic shift of basic sequence is fixed Adopted RS sequences (referring to equation 1).

Due to SF=5, so the multiplexing capacity of UCI data portions is 5.According to cyclic shift interval △_shift ^PUCCHCome true Determine the multiplexing capacity of the parts RS.Specifically, the multiplexing capacity of the parts RS isFor example, in △_shift ^PUCCH=1, △_shift ^PUCCH=2 and △_shift ^PUCCHIn the case of=3, multiplexing capacity is 12,6 and 4 respectively.In Figure 29 E to Figure 29 F, Due to SF=5, the multiplexing capacity of UCI data portions is 5, and in △_shift ^PUCCHIn the case of=3, the multiplexing of the parts RS is held Amount is 4.Therefore, entire multiplexing capacity is arranged to capacity 4 smaller in two capacity.

Figure 30 shows the structure of the PUCCH format 3 with increased multiplexing capacity.With reference to figure 30, SC-FDMA can be accorded with Number horizontal extension is applied to the parts RS in time slot.Therefore, make the multiplexing capacity of the parts RS double.That is, even if In the case of, the multiplexing capacity of the parts RS becomes 8, and the multiplexing capacity of UCI data portions is not lost.For the orthogonal of RS Code covering includes, but are not limited to, walsh coverings [y1y2]=[1 1], [1-1] or linear transformation form (for example, [j j], [j-j], [1j], [1-j] etc.).Y1 is applied to the first RSSC-FDMA symbols in time slot, and y2 is applied in time slot The 2nd RS SC-FDMA symbols.

Figure 31 shows the structure of another PUCCH format 3 with increased multiplexing capacity.If being not carried out the jump of time slot level Frequently, then extension or covering (such as Walsh coverings) can be additionally executed with time slot units, so that multiplexing capacity is double. In the case of executing the horizontal frequency hopping of time slot, if covered with time slot units application Walsh, due between the channel condition of time slot Difference and cause orthogonality impaired.The time slot units extended code (for example, orthogonal code covering) of RS is included, but are not limited to [x1x2]=[1 1], the Walsh coverings of [1-1] or its linear transformation form (for example, [j j] [j-j], [1j] [1-j] etc.). X1 is applied to the first time slot and x2 is applied to the second time slot.Although be shown in the accompanying drawings execute time slot horizontal extension (or Covering) and the case where extension (or covering) is then executed at SC-FDMA symbol levels, but sequence can be changed.

The signal handler that equation will be used to describe PUCCH format 3.For convenience it is assumed that using length 5OCC (for example, Figure 29 E to Figure 31).

First, using the specific scramble sequences of UE to bit block b (0) ..., b (M_bit- 1) it scrambles.Bit block b (0) ..., b (M_bit- 1) can with compiling bit b_0, b_1 of Figure 29 A ..., b_N-1 it is corresponding.Bit block b (0) ..., b (M_bit- 1) may be used To include at least one of ACK/NACK bits, CSI bits and SR bits.It can be generated according to following equatioies scrambled Bit block

Next, will description UL transmission modes configuration.Transmission mode for PUCCH can be roughly divided into two kinds Pattern.One is single antenna transmission mode and the other is multi-antenna transmission pattern.Single antenna transmission mode refers to passing as UE By the method for single antenna transmissions signal or make receiver (for example, BS) that single antenna transmissions can be identified by when defeated PUCCH Signal method.In multi-antenna transmission pattern, UE can use virtualization scheme (for example, PVS, day line options, CDD etc.) Signal is transmitted by mutiple antennas simultaneously.Multi-antenna transmission pattern instruction UE is passed through more days using transmission diversity or MIMO scheme Line transfers signals to BS.It, can be with use space orthogonal resource transmission diversity as the transmission diversity scheme used at this time (SORTD).In the present specification, for convenience's sake, multi-antenna transmission pattern is referred to as SORTD patterns, unless otherwise indicated.

Figure 32 shows signal processing blocks/program for SORTD.Exclude the basic program etc. except multi-antenna transmission processing In the program described with reference to figure 29 to Figure 31.With reference to figure 32, modulation symbol c_0 ..., c_23 carries out DFT- precompiles, and leads to Cross resource (for example, the OC, PRB or a combination thereof) transmission given based on each antenna port.In this example, although being more A antenna port executes a DFT operation, but can be based on every antenna port and execute DFT operations.In addition, though being replicated In the state of symbol d_0 ..., the d_23 of DFT- precompiles are transmitted by the 2nd OC/PRB, but can by the 2nd OC/PRB To transmit the modification (for example, conjugate complex number or scaling) of the symbol d_0 ..., d_23 of DFT- precompiles.For example, In order to ensure the orthogonality between the PUCCH signals by different antennae port transmission, [OC⁽⁰⁾≠OC⁽¹⁾；PRB⁽⁰⁾=PRB⁽¹⁾], [OC⁽⁰⁾=OC⁽¹⁾；PRB⁽⁰⁾≠PRB⁽¹⁾] and [OC⁽⁰⁾≠OC⁽¹⁾；PRB⁽⁰⁾≠PRB⁽¹⁾] it is possible.Here, in subscript Digital representation antenna port number or value corresponding thereto.

Figure 33 is the schematic diagram for illustrating SORTD operations.With reference to figure 33, UE obtains first resource index and Secondary resource index (S3310).Resource index (either resource value) indicates PUCCH resource index (or PUCCH resource value), and preferably 3 resource index of PUCCH format (or 3 resource value of PUCCH format).Step S3310 may include the multiple steps being sequentially performed Suddenly.The method for obtaining first resource index and Secondary resource index will be described in detail belows.Thereafter, UE passes through first antenna (port) transmits PUCCH signals (S3320) using PUCCH resource corresponding with first resource index.UE passes through second day Line (port) transmits PUCCH signals (S3330) using PUCCH corresponding with Secondary resource index.In identical subframe Execute step S3320 and S3330.

PUCCH signals may include hybrid automatic repeat-request response (HARQ-ACK).HARQ-ACK includes to downlink chain The response (for example, ACK, NACK, DTX or NACK/DTX) of road signal.If PUCCH includes HARQ-ACK, although being not shown, The program of Figure 33 further comprises the step of receiving down link signal.The step of receiving down link signal includes receiving to be used for The PDCCH of downlink scheduling and PDSCH corresponding with PDCCH.PUCCH format 3 is transmitted, can be connect on SCell Receive at least one of PDCCH and PDSCH.

As with reference to figure 32, to described in Figure 33, multiple antennas (port) transmits (for example, SORTD) and requires quantitatively than list The big orthogonal resource of stock number in antenna (port) transmission.For example, 2Tx SORTD transmission requirement orthogonal resources, quantity are Twice of stock number in single antenna (port) transmission.Therefore, antenna (port) transmission mode in the resource-area for PUCCH The quantity for the UE being multiplexed in domain, that is, multiplexing capacity is associated.Therefore, the quantity for the UE that BS needs basis is communicated with BS is neatly Configure antenna (port) transmission mode.For example, if small by the number of the BS UE received, can be configured relative to each UE Use multiple antennas (port) transmission mode (for example, SORTD patterns) also, if the number for passing through the BS UE received of multiple resources Amount is big, then can configure single antenna (port) transmission mode using single resource.It may be configured to by RRC signaling Antenna (port) transmission mode of PUCCH transmission.Furthermore it is possible to based on antenna (port) biography is independently configured per PUCCH format Defeated pattern.

Hereinafter, the present invention is proposed with PUCCH format 3 using multiple resources for multiple antennas (port) transmission The various methods of resource (referring to the step S3310 of Figure 33) are distributed under environment.For example, if 2Tx SORTD are applied to PUCCH Format 3, then since it is desired that two orthogonal resources, so needing the allocation rule of two orthogonal resources.

First, the single antenna (port) of an orthogonal resource is required to transmit description.Resource point for PUCCH format 3 With being distributed based on explicit resource.More specifically, UE can be used by higher level (for example, RRC) signaling by aforehand explicit allocation In PUCCH format 3 PUCCH resource value candidate (or PUCCH resource value Candidate Set) (for example,)。 Thereafter, ACK/NACK (A/N) resource indicator (ARI) (HARQ-ACK resource values) can be transferred to UE by BS, and UE can be with Determine the PUCCH resource value for being transmitted by the practical PUCCH of ARIPUCCH resource valueIt is mapped to PUCCH resource (for example, OC or PRB).ARI can be used for directly indicating which provided by higher level in advance will be used PUCCH resource value is candidate (or PUCCH resource value Candidate Set).In the implementation, ARI can indicate to pass through signal (by higher level) Send the deviant of PUCCH resource value.The transimission power of the PDSCH- scheduling PDCCH (SCellPDCCH) transmitted on SCell Control (TPC) can be re-used as ARI.The TPC words of the PDSCH- scheduling PDCCH (PCell PDCCH) transmitted on PCell Section can be used for the PUCCH power controls for its original applications.In the case of 3GPP versions 10, because the PDSCH of PCell is not Allow to dispatch from the cross carrier wave of SCell, reception PDSCH can be equivalent to only on PCell only receives PDCCH on PCell.

More specifically, it if being used for the PUCCH resource of A/N by RRC distribution in advance, can determine as follows for real The resource of the PUCCH transmission on border.

PDCCH (or PDCCH on SCell corresponding with PDSCH) instruction corresponding with the PDSCH on SCell Pass through one of RRC PUCCH resources configured using ARI (HARQ-ACK resource values).

If not detecting PDCCH corresponding with the PDSCH on SCell (or SCells corresponding with PDSCH On PDCCH) and receive PDSCH on PCell, then any one in following methods is applicable：

(the minimum of PDCCH is configured using according to the implicit A/N PUCCH resources of existing 3GPP versions 8 that is, using The PUCCH format 1a/1b resources that CCE is obtained).

PDCCH (or PDCCH on PCell corresponding with PDSCH) corresponding with the PDSCH on PCell refers to Show and passes through one of RRC PUCCH resources configured using ARI (HARQ-ACK resource values).

Assume all PDCCH corresponding with the PDSCH on SCell (or on SCell corresponding with PDSCH PDCCH) ARI (HARQ-ACK resource values) having the same.

ARI (HARQ-ACK resource values) can have X bits, and if the TPC fields of SCell PDCCH are made again With then X can be 2.For convenience it is assumed that X=2.

Hereinafter, by description for supporting various antennas (port) if transmitting control information using PUCCH format 3 The resource allocation methods of transmission mode.

For example, UE can be allocated for four of PUCCH format 3 just by RRC signaling (for example, four RRC signals) Resource is handed over, for example, PUCCH resource value WithIn addition, UE can be assigned by four One collection of PUCCH resource value compositionAs a RRC signal.Thereafter, UE can be with Detect PDCCH signals and the PDSCH signals of reception corresponding thereto.PDCCH signals and PDSCH can be received by SCell At least one of signal.Thereafter, UE can be according to the bit value of the ARI (HARQ-ACK resource values) in PDCCH signals come really Surely it is used for the PUCCH resource value of actual PUCCH transmissionIdentified PUCCH resource value is mapped to PUCCH resource (for example, OC or PRB).Using the PUCCH resource of mapping PUCCH resource value by network (for example, BS or relay nodes (RN) UCI (for example, HARQ-ACK for PDSCH) is transmitted.The above method is shown in table 16.

Table 16

Wherein, HARQ-ACK instructions respond the HARQACK/NACK/DTX of downlink transmission block.HARQ ACK/ NACK/DTX responses include ACK, NACK, DTX and NACK/DTX.

If it is assumed that using the TPC fields transmission ARI (HARQ-ACK resource values) of SCell PDCCH, if UE only exists PDSCH (PDCCH is only received on PCell) is received on PCell, then nonrecognition ARI or PUCCH resource associated with ARI Value.It therefore, can be using existing 3GPP versions 8/9PUCCH resources and version 8/9PUCCH formats if event occurs The candidate mode (fall-back) of 1a/1b.

Next, the method that distribution is used for transmission multiple orthogonal resources of diversity (for example, SORTD) will be described.In order to For the sake of convenient, it is assumed that use two orthogonal resources.

In the following description, consider that the actual transmissions pattern of UE performances or UE can be distributed for multi-antenna port biography Defeated required resource (collection).For example, if UE supports multi-antenna port transmission, BS that can in advance distribute for multi-antenna port The Secondary resource (collection) of transmission and first resource (collection) for single antenna port transmission.Thereafter, UE can be in single antenna port First resource (collection) is used in transmission mode, and first resource (collection) and the second money are used in multi-antenna port transmission mode Source (collection).In addition, the current transmission mode of UE can be considered to distribute the Secondary resource (collection) transmitted for multi-antenna port in BS. For example, BS can distribute the Secondary resource (collection) for UE after instruction UE is operated under multi-antenna port transmission mode.That is, After only configuring multi-antenna port transmission mode in the state of distributing first resource (collection), UE configures first with being attached Resource (collection).

For example, UE can substantially receive distribution information of the instruction for multiple PUCCH resources of antenna port p0, and Even if can additionally receive instruction when multi-antenna port transmission is possible or configuration multi-antenna port transmission mode to use In the distribution information of multiple PUCCH resources of antenna port p1.

In this case, UE can be allocated for PUCCH format by RRC signals (for example, eight RRC signals) 3 eight orthogonal resources, for example, PUCCH resource value AndIn addition, UE can pass through one RRC signals are assigned a collection being made of eight PUCCH resource valuesThereafter, UE can detect PDCCH letters Number and PDSCH signals corresponding thereto.At least one of PDCCH signals and PDSCH signals can be received by SCell. Thereafter, UE can determine that being used for practical PUCCH passes according to the bit value of the ARI (HARQ-ACK resource values) in PDCCH signals Defeated PUCCH resource valueP indicates antenna port number or value corresponding thereto.Identified PUCCH resource value It is mapped to PUCCH resource (for example, OC or PRB).Pass through network (example using the PUCCH resource for being mapped with PUCCH resource value Such as, BS or relay node (RN)) transmission UCI (for example, HARQ-ACK for PDSCH).

In multi-antenna port transmission mode, an ARI is used to indicate multiple PUCCH resource values.By the multiple of ARI instructions PUCCH resource value is mapped to the PUCCH resource for respective antenna port.Therefore, it is according to antenna port transmission mode Single antenna port mode or multi-antenna port pattern, ARI can indicate one or more PUCCH resource value.In table 17 Method as described above is shown.

Table 17

As another example, UE can be based on being distributed four orthogonal resources as follows by RRC signaling per antenna port (for example, PUCCH resource value).Thereafter, UE can detect PDCCH signals and the PDSCH signals of reception corresponding thereto.Pass through SCell can receive at least one of PDCCH signals and PDSCH signals.Thereafter, UE can be according to the ARI in PDCCH signals The bit value of (HARQ-ACK resource values) determines final PUCCH resource value to be used based on every antenna portInstitute is really Fixed PUCCH resource value is mapped to the PUCCH resource (for example, OC or PRB) for each antenna port.P marker antennas Port numbering or value corresponding thereto.The method is shown in table 18.

-->For antenna port p0 (for example, p0=0)

–->For antenna port p1 (for example, p1=1).

But it is unrestricted, as described above, UE, which can be received substantially, indicates multiple PUCCH's for antenna port p0 Information is distributed, and and if only if multi-antenna port transmission can be received additionally when being possible or configuration multi-antenna transmission pattern Indicate the distribution information of multiple PUCCH resources for antenna port p1.

Table 18

If multi-antenna port transmission is possible or configuration multi-antenna port transmission mode, UE can pass through one RRC signals are substantially allocated for four orthogonal resources of single antenna port transmission, for example, PUCCH resource valueAnd two can be allocated for by a RRC signal Eight orthogonal resources of a antenna port, for example, PUCCH resource valueUE can be according to the bit of ARI Value determines final PUCCH resource value to be used based on per antenna portPUCCH resource corresponding thereto.In table The above method is shown in 19.

Table 19

Table 17 to 19 shows that the part p=p0 of the distribution of the PUCCH resource value for multi-antenna port is configured to be equal to Situation in single antenna port.That is, assuming nested structure in table 17 to 19.Therefore, a common block list can support Dan Tian Both line end port transmission and multi-antenna port transmission.

Reference table 18, will be described in further detail nested structure.In nested structure, a common block list can be used.Table 20 show the common block list for single antenna port transmission pattern and multi-antenna port transmission mode.

Table 20

If UE is configured to single antenna port transmission pattern associated with PUCCH transmission, can divide such as table 21 Analyse table 20.Therefore, if UE is configured to single antenna port transmission pattern, pass through the PUCCH resource value of ARI instructions It is eventually mapped to a PUCCH resource for single antenna port (for example, p0)

Table 21

If UE is configured to multi-antenna port transmission mode associated with PUCCH transmission, can divide such as table 22 Analyse table 20.Therefore, if UE is configured to multi-antenna port transmission mode, pass through the PUCCH resource value of ARI instructions It is eventually mapped to multiple PUCCH resources for mutiple antennas port (for example, p0 and p1)With

Table 22

It will be described as another example that distribution is used for transmission more (for example, two) a orthogonal resources of diversity, that is, SORTD. For example it is assumed that being allocated for four orthogonal resources of PUCCH format 3, example by RRC signals (for example, four RRC signals) UE Such as, PUCCH resource valueAndAlternatively, it can be assumed that pass through a RRC Signal UE is assigned a collection being made of four resource valuesAs described above, UE can To determine final PUCCH resource to be used based on per antenna port according to the bit value of ARIBased on above it is assumed that According to this example, four PUCCH resource values can be divided into groupAnd groupTwo groups.In this case, a ratio of a bit of the preceding part of ARI and rear part Spy could be used to indicate that the resource for respective group.For example it is assumed that ARI forms (each of b0 and b1 by b0 and b1 It is 0 or 1).In this case, which PUCCH resource value b0 instructions use in group 0, and b1 instructions are in group 1 Which PUCCH resource value used.The PUCCH resource value selected from group 0 can be mapped to for antenna port p0's PUCCH resource (for example, OC or PRB), and the resource selected from group 1 can be mapped to for antenna port p1's PUCCH resource (for example, OC or PRB).

The above method is shown in table 23.Although this method can be applied to distribute four PUCCH resources by RRC signaling ValueAndThe case where, but this method can be applied to use more orthogonal resources The case where.

Table 23

Table 23 shows that every individual antenna receives the signal (in the case of 2Tx, total of four) by two RRC signals, And the case where resource of each bit instruction of ARI for each antenna port.Table 24 shows to distribute antenna port p0And antenna port p1 is distributedThe case where.

Table 24

As another example of the present invention, by the method for downlink assignment indexing of description in the case of TDD CA. DAI is the value obtained by counting scheduled PDCCH in the time domain, and is for domain cell (or CC) in CA Expansible.In the case of PUCCH format 3, because DAI values are not required, DAI can be used in the present invention.

For example, 3 resource of PUCCH format for first antenna port (p=p0) can be distributed/determine using ARI, and DAI distribution/determination can be used to be used for the PUCCH format resource of the second antenna port (p=p1).It can be by serving cell PDCCH is limited to DAI values having the same, with for the PDCCH of at least one serving cell failure in the case of prepare.Such as Fruit only dispatches PDSCH on PCell, then UE can ignore the DAI values of PCellPDCCH corresponding with PDSCH, return to Dan Tian Line port mode, and transmit PUCCH.

For convenience it is assumed that four orthogonal resources are distributed in advance by RRC signaling UE, for example, PUCCH resource valueAndThereafter, if it is assumed that UE receptions include ARI=[00] and DAI=[10] PDCCH signals.

-->For antenna port p0 (for example, p0=0)

–->For antenna port p1 (for example, p1=1)

The above method is shown in table 25.

Table 25

In addition, identical method can be applied to following situations, that is, distributed eight orthogonal moneys in advance by RRC signaling UE Source, for example, PUCCH resource value For example, the ARI values 00,01,10 and 11 for antenna port 0 indicate respectivelyAndAnd the DAI values 00,01,10 and 11 for antenna port 1 indicate respectively With And

As another example, it is based on that four orthogonal resources can be distributed as follows by RRC signaling UE per antenna port.

–->For antenna port p0 (for example, p0=0)

-->For antenna port p1 (for example, p1=1)

At this moment, ARI values 00,01,10 and 11 indicate respectivelyAndAnd DAI values 00,01,10 and 11 indicate respectively
