In radio communications system, subscriber equipment (UE) in down link (DL) from the base station (BS) reception information, and in up link (UL) with communication to BS.Transmission or the information that receives comprise data and various control information between BS and UE, and have various physical channels according to the kind of the information that is transmitted or receives/use.

Fig. 1 illustrates the view for the universal signal transmission method of the physical channel of third generation partner program (3GPP) Long Term Evolution (LTE) system and this physical channel of use.

When the UE plugged or when UE reenters the residential quarter, UE carries out such as the synchronous search of initial zone with BS and operates in step S101.For search of initial zone operation, UE can receive primary synchronization channel (P-SCH) and auxiliary synchronization channel (S-SCH) from BS, carrying out synchronous with BS, and obtains the information such as residential quarter ID.Thereafter, UE can receive Physical Broadcast Channel from BS, and obtains the broadcast message in the residential quarter.Simultaneously, UE can be in the search of initial zone step receiving downlink reference signal (DL RS), and confirm downlink channel status.

The UE that finishes search of initial zone can receive physical downlink control channel (PDCCH) and the physical down link sharing channel (PDSCH) corresponding with PDCCH, and obtains more detailed system information in step S102.

Thereafter, UE can carry out random joining procedure in step S103 to S106, so that finish the access to eNB.For random joining procedure, UE can be via Physical Random Access Channel (PRACH) transmission preamble (S103), and can be in response to leading via PDCCH and the PDSCH receipt message (S104) corresponding with PDCCH.In the random access based on competition, can carry out the competition settlement procedure of the reception (S106) that comprises additional PRACH transmission (S105) and PDCCH and the PDSCH corresponding with it.

Then the UE that carries out said procedure can receive PDCCH/PDSCH(S107) and transmitting physical uplink shared channel (PUSCH)/physical downlink control channel (PUCCH) is (S108), as general uplink/downlink signal transmission procedure.The control information that is transferred to BS from UE is collectively referred to as uplink control information (UCI).UCI comprises mixed automatic retransfer request-reply/negative response (HARQ ACK/NACK), dispatch request (SR), CQI (CQI), precompile matrix designator (PMI), order designator (RI) etc.In this manual, HARQ ACK/NACK is called HARQ-ACK or ACK/NACK(A/N for short).HARQ-ACK comprises sure ACK(ACK), negate ACK(NACK), among DTX and the NACK/DTX at least one.Usually via PUCCH transmission UCI.Yet, in the situation of control information transmission and business datum, can transmit UCI via PUSCH at the same time.Can transmit aperiodically UCI via PUSCH according to network request/instruction.

Fig. 2 is the schematic diagram that the structure of radio frame is shown.In cellular OFDM radio packet communication system, in subframe unit, carry out the uplink/downlink data packet transfer, and be the predetermined duration that comprises a plurality of OFDM symbols with a subframe definition.The support of 3GPP LTE standard may be used on the Class1 radio frame structure of Frequency Division Duplexing (FDD) (FDD) and may be used on type 2 radio frame structures of time division duplex (TDD).

Fig. 2 (a) illustrates the structure of Class1 radio frame.The downlink radio frame comprises 10 subframes, and a subframe comprises two time slots in time domain.Transmit a subframe required time and be called as Transmission Time Interval (TTI).For example, a subframe has 1 millisecond length, and a time slot has 0.5 millisecond length.A time slot comprises a plurality of OFDM symbols and comprise a plurality of Resource Block (RB) in frequency domain in time domain.In 3GPP LTE system, because in down link, use OFDMA, so symbolic component of OFDM symbol indication.The OFDM symbol can be called SC-FDMA symbol or symbolic component.RB as resource allocation unit can comprise a plurality of continuous subcarriers in a time slot.

The quantity of the OFDM symbol that comprises in a time slot can change according to the configuration of Cyclic Prefix (CP).CP comprises expansion CP and normal CP.For example, if configure the OFDM symbol by normal CP, the quantity of the OFDM symbol that then comprises in a time slot can be 7.If by expansion CP configuration OFDM symbol, then because the length of an OFDM symbol is increased, the quantity of the OFDM symbol of normal CP so the quantity of the OFDM symbol that comprises in a time slot is less than.In the situation that expansion CP, for example, the quantity of the OFDM symbol that comprises in a time slot can be 6.In the unsettled situation of channel status, such as the situation of UE high-speed mobile, can use expansion CP so that further reduce intersymbol interference.

In the situation that use normal CP, because a time slot comprises seven OFDM symbols, so a subframe comprises 14 OFDM symbols.Simultaneously, maximum three OFDM symbols of each subframe can be assigned to physical downlink control channel (PDCCH), and remaining OFDM symbol can be assigned to physical down link sharing channel (PDSCH).

Fig. 2 (b) illustrates the structure of type 2 radio frames.Type 2 radio frames comprise two fields, and every half frame comprises five subframes, down link pilot timeslot (DwPTS), protective time slot (GP) and uplink pilot time slot (UpPTS).In the middle of these, a subframe comprises two time slots.DwPTS is used for the search of initial zone of UE, synchronous or channel estimating.It is synchronous that UpPTS is used for the ul transmissions of the channel estimating of BS and UE.GP is used to eliminate because the interference that the multipath delay of the down link signal between up link and down link produces in up link.

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

Fig. 3 A is illustrated in the view of the signal handler of UE place transmit uplink (UL) signal.

In order to transmit the UL signal, the signal that the scrambling module 210 of UE can come scrambling to be transmitted with the specific scrambled signals of UE.Scrambled signals is input to modulation mapper 220, so that according to the kind of the signal that is transmitted and/or the channel status scheme by two-phase PSK (BPSK), quarternary phase-shift keying (QPSK) (QPSK) or 16-quadrature amplitude modulation (16QAM)/64-QAM it is modulated into complex symbol.By conversion precompile device 203 process modulated complex symbol and be entered into resource element mapper 204 thereafter.Resource element mapper 204 can be mapped to complex symbol the time-frequency resources element.Can be transferred to BS via the signal that SC-FDMA signal generator 205 and antenna will have been processed.

Fig. 3 B is the schematic diagram at the signal handler of BS communicating downlink (DL) signal.

In 3GPP LTE system, BS can transmit one or more code words in down link.Therefore, can process one or more code word with by scrambling module 301 and modulation mapper 302 configuration complex symbols, be similar to the UL transmission of Fig. 3 A.Can by layer mapper 303 complex symbol be mapped to a plurality of layers, and each layer can by precompile module 304 be multiplied by precompile matrix and can be assigned to each transmit antenna thereafter.To can be mapped to the time-frequency resources element by resource element mapper 305 via the signal of having processed that antenna transmits respectively, and can be transmitted respectively via OFDMA signal generator 306 and antenna.

In radio communications system, in the situation that UE signal transmission in up link is compared with BS situation of signal transmission in down link, peak to average power ratio (PAPR) may more be a problem.Therefore, as describing in the above with reference to figure 3A and 3B, the OFDMA scheme is used for transmitted downlink signal, and the SC-FDMA scheme is used for transmitting uplink signals simultaneously.

Fig. 4 is the schematic diagram of explaining SC-FDMA scheme and OFDMA scheme.In the 3GPP system, in down link, use the OFDMA scheme and in up link, use SC-FDMA.

With reference to figure 4, the BS something in common that is used for the UE of UL signal transmission and transmits for the DL signal is, comprises that leaf inverse transformation (IDFT) module 404 in series connection-parallel convertor 401, subcarrier mapper 403, the M point discrete Fourier, multiple-series transducer 405 and Cyclic Prefix (CP) add module 406.Be used for using the UE of SC-FDMA scheme signal transmission also to comprise N point DFT module 402.The IDFT that N point DFT module 402 partly is offset M point IDFT module 404 processes impact, so that the signal that is transmitted has single-carrier property.

Figure 13 is illustrated in PUCCH form 1a and the 1b in the situation of normal CP.Figure 14 is illustrated in PUCCH form 1a and the 1b in the situation of expanding CP.In PUCCH form 1a and 1b structure, in the subframe take time slot as unit, repeat identical control information.Each UE is by different resource transferring ACK/NACK signal, and this different resource comprises that quadrature covers the different cyclic shift (frequency domain code) of zero auto-correlation (CG-CAZAC) sequence of constant amplitude that (OC) or orthogonal covering codes (OCC) (time field code) and computer generate.For example, OC comprises the Walsh/DFT orthogonal code.If the quantity of CS be 6 and the quantity of OC be 3 o'clock, then in the situation that use single antenna can be in identical physical resource storehouse (PRB) multiplexing altogether 18 UE.Can in specific time domain (after the FFT modulation) or specific frequency domain (before the FFT modulation), use orthogonal sequence w0, w1, w2 and w3.

For SR and continuous dispatching, can control by radio resource (RRC) and will comprise that the ACK/NACK Resource Supply of CS, OC and PRB is to UE.For dynamic ack/NACK and non-continuous dispatching, the ACK/NACK resource impliedly can be distributed to UE by the minimum CCE index of the PDCCH corresponding with PDSCH.

Figure 15 is illustrated in the PUCCH form 2/2a/2b in the situation of normal CP.Figure 16 is illustrated in the PUCCH form 2/2a/2b in the situation of expanding CP.With reference to Figure 15 and Figure 16, in the situation that normal CP, except the RS symbol, a subframe comprises 10 QPSK data symbols.In frequency domain, expand each QPSK symbol by CS, and then it is mapped to corresponding SC-FDMA symbol.Can use the horizontal CS frequency hopping of SC-FDMA symbol, so that the presence of intercell interference randomization.Use CS can multiplexing RS by CDM.For example, be 12 or 6 if suppose the quantity of available CS, then can be in identical PRB multiplexing 12 or 6 UE.For example, in PUCCH form 1/1a/1b and 2/2a/2b, can multiplexing a plurality of UE by CS+OC+PRB and CS+PRB.

Multicarrier system or carrier aggregation system refer to for polymerization and utilize the system of a plurality of carrier waves to support to be used for the broadband, and these a plurality of carrier waves have the bandwidth less than the target bandwidth.For with the back compatible of existing system, when having a plurality of carrier waves less than the bandwidth of target bandwidth when being aggregated, the bandwidth of the carrier wave that is aggregated can be limited to the bandwidth of using in the existing system.For example, existing LTE system can support 1.4,3,5,10,15 and the bandwidth of 20MHz, and from the senior LTE(LTE-A of LTE system evolved) system can only use the bandwidth support supported by the LTE system greater than the bandwidth of 20MHz.Alternatively, no matter the bandwidth of using in existing system can define new bandwidth, to support CA.Multicarrier can use with CA and bandwidth aggregating switching ground.CA comprises continuous CA and discrete CA.

Figure 20 is the concept map of the management of down link component carrier in BS, and Figure 21 is the concept map of the management of up link component carrier in UE.For the convenience of describing, suppose that higher level is the MAC layer in Figure 20 and Figure 21.

Figure 22 is the concept map of the situation of a MAC layer-management multicarrier in BS.Figure 23 is the concept map of the situation of a MAC layer-management multicarrier in UE.

With reference to Figure 22 and Figure 23, the one or more frequency carriers of MAC layer-management are to carry out transmission and to receive.Because the frequency carrier by a MAC layer-management needs not be mutually continuous, so resource management is flexibly.In Figure 22 and Figure 23, for convenience's sake, a physics (PHY) layer means the one-component carrier wave.A PHY layer must not mean independently radio frequency (RF) equipment.Usually, one independently RF equipment mean a PHY layer, but the invention is not restricted to this.A RF equipment can comprise several PHY layers.

Figure 24 is the concept map of the situation of a plurality of MAC layer-management multicarriers in BS.Figure 25 is the concept map of the situation of a plurality of MAC layer-management multicarriers in UE, and Figure 26 is another concept map of the situation of a plurality of MAC layer-management multicarriers in BS, and Figure 27 is another concept map of the situation of a plurality of MAC layer-management multicarriers in UE.

Except the structure shown in Figure 22 and Figure 23, several MAC layers can be controlled several carrier waves, as shown in Figure 24 to Figure 27.

As shown in Figure 24 and Figure 25, each MAC layer can be controlled each carrier wave correspondingly, and as shown in Figure 26 and Figure 27, each carrier wave can be controlled correspondingly with respect to each MAC layer of some carrier waves, and one or more carrier wave can be controlled with respect to MAC layer of remaining carrier wave.

System comprises such as a plurality of carrier waves of a carrier wave to N carrier wave, and carrier wave can be continuous or discrete, no matter UL/DL.The TDD system is configured to management many (N) individual carrier wave in DL and UL transmission.The FDD system is configured to so that use a plurality of carrier waves in each of UL and DL.In the situation that the FDD system can support asymmetric CA, the quantity of the bandwidth of the quantity of the carrier wave of polymerization and/or carrier wave is different in UL and DL in asymmetric CA.

When the quantity of the component carrier of polymerization in UL and DL is identical, can configure all component carriers so that with the existing system back compatible.Yet the present invention does not get rid of the component carrier of not considering compatibility.

Hereinafter, for the convenience of describing, suppose that the PDSCH corresponding with PDCCH is by DL component carrier #0 transmission when by DL component carrier #0 transmission PDCCH.Yet, can use the intersection carrier dispatching, and can be by another DL component carrier transmission PDSCH.Term " component carrier " can be replaced by another equivalent terms (for example, residential quarter).

Figure 28 illustrates the wherein scene of transmitting uplink control information (UCI) in the wireless communication system of supporting CA.For convenience's sake, in this example, suppose that UCI is ACK/NACK(A/N).UCI can comprise control information channel condition information (for example, CQI, PMI, RI etc.) or dispatch request information (for example, SR etc.).

Figure 28 is the schematic diagram that the asymmetric CA that 5 DL CC and UL CC be linked is shown wherein.Can asymmetric CA be set from the visual angle of UCI transmission.That is the DL CC-UL CC link that, can differently be provided for the DL CC-UL CC link of UCI and be used for data.For convenience's sake, can transmit maximum two code words if suppose a DL CC, then the number of ULACK/NACK bit is two at least.Under these circumstances, in order to transmit the ACK/NACK of the data that receive by 5 DL CC by a ULCC, need the ACK/NACK of at least 10 bits.In order to support the DTX state of each DL CC, for the ACK/NACK transmission, need at least 12 bits (5^5=3125=11.61 bit).Because can transmit the ACK/NACK of maximum 2 bits with existing PUCCH form 1a/1b, so the ACK/NACK information that such structure can not transmitting extended.For convenience's sake, although described wherein because CA increases the example of UCI amount of information, because the existence of the backhaul subframe in increase, TDD system and the delay system of antenna amount etc. may increase the UCI amount of information.Similar to the situation of ACK/NACK, when by UL CC transmission during with control information that a plurality of DL CC are associated, the control information amount increase that be transmitted.For example, must be used for to increase the CQI payload in the CQI situation of a plurality of DL CC by UL anchor (perhaps main) CC transmission.

DL master CC can be defined as the DL CC that links with UL master CC.Link comprises the implicit expression link and shows link.In LTE, a DL CC and a UL CC are matched inherently.For example, by the LTE pairing, the DL CC that links with UL master CC can be called as DL master CC.This can be considered to the implicit expression link.Show the configured in advance link of link indication network and send with signal by RRC etc.In showing link, the DL CC that matches with UL master CC can be called as main DL CC.UL master's (or anchor) CC can be the UL CC of transmission PUCCH.Alternatively, UL master CC can be the UL CC by PUCCH or PUSCH transmission UCI.Can be by higher level signal deployment DL master CC.DL master CC can be the DL CC that UE carries out initial access.DL CC except DL master CC can be called as the auxiliary CC of UL.Similarly, the UL CC except UL master CC can be known as the auxiliary CC of UL.

LTE-A uses the concept of residential quarter so that managing radio resources.The residential quarter is defined as the combination of down-chain resource and uplink resource and the uplink resource component that is not absolutely necessary.Therefore, the residential quarter can only be comprised of separately down-chain resource or can be comprised of the combination of down-chain resource and uplink resource.If support CA, then the link between down-chain resource carrier frequency (perhaps DL CC) and uplink resource carrier frequency (or UL CC) can be indicated by system information.Residential quarter (or PCC) with the basic frequency operation can be called main plot (PCell), and can be called auxiliary residential quarter (SCell) with the residential quarter (perhaps SCC) of less important frequency (secondary frequency) operation.Can respectively DL CC and UL CC be called DL residential quarter and UL residential quarter.In addition, can respectively anchor (perhaps main) DL CC and anchor (or main) UL CC be called DL PCell and UL PCell.PCell is used to rebulid processing by UE execution initial connection foundation processing or connection.PCell also can indicate the residential quarter at the hand-off process indicating.After carrying out RRC connection foundation, SCell can be configured, and additional radio resources can be used for providing.PCell and SCell can be referred to as Serving cell.Therefore, in the situation that UE is in the RRC_CONNECTED state and is not configured with CA or does not support CA, only have a Serving cell, this Serving cell only comprises PCell.On the contrary, in the situation that UE is in the RRC_CONNECTED state and is configured with CA, exist one or more Serving cells and each Serving cell to comprise PCell and all SCell.For CA, except connecting the PCell that sets up initial configuration in the processing, network can be for supporting one or more SCell of the UE configuration of CA after the activation of beginning initial safe is processed.

Can only definition DL-UL pairing in FDD.Because TDD uses same frequency, so can not define the DL-UL pairing.By UL E-UTRA absolute radio frequency channel number (EARFCN) information of SIB2, link can be determined the DL-UL link according to UL.For example, between initial access periods, the DL-UL link can be obtained by the SIB2 decoding, and in other mode, the DL-UL link can be obtained by the RRC signaling.Therefore, can there be only SIB2 link, and do not define clearly other DL-UL pairings.For example, in the 5DL:1UL of Figure 28 structure, DL CC#0 and UL CC#0 can have SIB2 linking relationship and remaining DL CC and other the UL CC that is not arranged to UE can have relation.

In order to support the scene such as Figure 28, need new scheme.Hereinafter, the PUCCH form (for example, a plurality of A/N bits) that is used for the feedback of UCI in supporting the communication system of carrier aggregation is called as CA PUCCH form (perhaps the PUCCH form 3).For example, PUCCH form 3 is used to transmit and the PDSCH(that receives at many DL Serving cell or PDCCH) corresponding A/N information (possibly, comprising the DTX state).

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

The PUCCH form that Figure 29 A illustrates according to the present embodiment is applied to the normal CP of PUCCH form 1() the situation of structure.With reference to figure 29A, channel compiling piece to information bit a_0, a_1 ... and a_M-1(for example, a plurality of ACK/NACK bits) carry out the channel compiling and generate compiling bit (bit that has been compiled or the bit that is compiling) (or code word) b_0, b_1 ... and b_N-1.M represents the size of information bit, and the size of N presentation code bit.Information bit comprises UCI, for example, is used for a plurality of ACK/NACK bits by a plurality of data (or PDSCH) of a plurality of DL CC receptions.No matter kind/quantity of the UCI of configuration information bit/size, information bit a_0, a_1 ..., and a_M-1 united compiling.For example, if information bit comprises a plurality of ACK/NACK data for a plurality of DL CC, then do not carry out the channel compiling with respect to each DL CC or each ACK/NACK bit, but carry out the channel compiling with respect to whole bit information.Therefore generate single codeword.Channel compiling can include, but are not limited to simple repetition, single worker compiling, Reed-bridle (RM) and compile, deletes remaining RM compiling, stings tail convolutional encoding (TBCC), low-density check (LDPC) and turbo and compile.Although not shown, consider order of modulation and stock number, can carry out rate-matched to coded-bit.The rate-matched function can be included in the channel compiling piece or can carry out with independent functional block.For example, channel compiling piece can be carried out (32,0) RM with respect to a plurality of control informations and compile to obtain single codeword and execution circular buffering rate-matched.

Bit b_0, b_1 that modulators modulate is compiled ..., and b_N-1, and generate modulation symbol c_0, c_1 ..., and c_L-1.L represents the size of modulation symbol.Amplitude and the phase place of the signal that is transmitted by change are carried out modulator approach.For example, modulator approach comprises n-phase shift keying (n-PSK), n-quadrature amplitude modulation (qam) (wherein n is greater than or equal to 2 integer).More specifically, modulator approach can comprise binary system PSK(BPSK), quadrature PSK(QPSK), 8-PSK, QAM, 16-QAM, 64-QAM etc.

Divide device with modulation symbol c_0, c_1 ..., and c_L-1 be divided into time slot.Modulation symbol is divided into the particularly restriction of the order/pattern of time slot/method.For example, dividing device begins modulation symbol sequentially is divided into time slot (local type) from header.In this case, as directed, can with modulation symbol c_0, c_1 ... and c_L/2-1 is divided into time slot 0, and can with modulation symbol c_L/2, c_L/2+1 ... and c_L-1 is divided into time slot 1.Modulation symbol can be interleaved (perhaps arranging) when being divided into time slot.For example, the modulation symbol of even-numbered can be divided into the time slot 0 and modulation symbol of odd-numbered can be divided into time slot 1.Can change modulation treatment and divide the order of processing.Substitute different compiling bits is divided into time slot, identical compiling bit can be configured to repeat with time slot unit.Under these circumstances, can omit the division device.

DFT precompile device is carried out DFT precompile (for example, 12 DFT) with respect to the modulation symbol that is divided into time slot, to generate single carrier waveform.With reference to the accompanying drawings, can be divided into time slot 0 modulation symbol c_0, c_1 ... and c_L/2-1DFT prelist be translated into DFT symbol d_0, d_1 ... and d_L/2-1, and be divided into time slot 1 modulation symbol c_L/2, c_L/2+1 ... and c_L-1 by DFT prelist be translated into DFT symbol d_L/2, d_L/2+1 ... and d_L-1.The DFT precompile can be replaced by another linear operation (for example, Walsh precompile).DFT precompile device can be replaced by the CAZAC modulator.The CAZAC modulator utilize corresponding sequence modulation be divided into 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 symbol d_0, d_1 ..., d_l/2-1 and d_L/2, d_L/2+1 ..., and d_L-1.For example, the CAZAC modulator comprises the CAZAC sequence or is used for the sequence of (CG) 1RB that the LTE computer generates.For example, if LTE CG sequence be r_0 ..., and r_L/2-1, then the CAZAC modulation symbol can be d_n=c_n*r_n or d_n=conj (c_n) * r_n.

Extension blocks locates to expand the signal that stands DFT in SC-FDMA symbol level (time domain).Use extended code (sequence) to carry out the time domain expansion of SC-FDMA symbol level.Extended code comprises quasiorthogonal code and orthogonal code.Quasiorthogonal code can include, but are not limited to pseudo noise (PN) code.Orthogonal code can include, but are not limited to Walsh code and DFT code.Although orthogonal code is described as the representative example of extended code for the ease of description of the invention, orthogonal code only is exemplary and can be replaced by quasiorthogonal code.Limited the maximum of extended code size (perhaps spreading factor (SF)) by the quantity of the SC-FDMA symbol that is used for control information transmission.For example, four SC-FDMA symbols are used for transmission in the situation of the control information of a time slot, in each time slot, can use (puppet) orthogonal code w0, w1, w2 and w3 with length 4.SF means the degree of expansion of control information, and is associated with the multiplexing exponent number of UE or the multiplexing exponent number of antenna.SF can become 1,2,3,4 according to the demand of system ..., and can be between BS and UE predefined or can pass through DCI or RRC signaling UE.For example, deleted in the remaining situation with transmitting SRS at one of SC-FDMA symbol that is used for control information, the extended code with SF value (for example, SF=3 rather than SR=4) of minimizing can be applied to the control information of time slot.

The signal that generates by said procedure can be mapped to the subcarrier among the PRB, stands IFFT, and is converted into time-domain signal.The SC-FDMA symbol that time-domain signal is attached with CP and is generated transmitted by the RF stage.

Suppose that transmission is used for the ACK/NACK of 5 DL CC, will describe each program in detail.In the situation that each DL CC can transmit two PDSCH, the number of ACK/NACK bit can be 12 if the DTX state is included.Consider the temporal extension of QPSK modulation and SF=4, compiling block size (after rate-matched) can be 48 bits.The bit modulation of compiling can be become 24 QPSK symbols, and 12 symbols in the QPSK symbol that generates are divided into each time slot.In each time slot, convert 12 QPSK symbols to 12 DFT symbols by 12 DFT operations.In each time slot, use in time domain, to have the extended code of SF=4 with 12 DFT sign extended to four SC-FDMA symbol and mapping.Because by 12 bits of [2 bits * 12 subcarrier+8 SC-FDMA symbols] transmission, so compiler rate is 0.0625(=12/192).In the situation that SF=4, every PRB can be multiplexing up to four UE.

The signal handler of describing with reference to figure 29A only is exemplary, and the signal that is mapped to PRB in Figure 29 A can use the signal handler of various equivalences and obtains.The signal handler that is equivalent to Figure 29 A is described with reference to Figure 29 B to Figure 29 G.

Figure 29 B is different from Figure 29 A in the order of DFT precompile device and extension blocks.In Figure 29 A, because the function of extension blocks equals from the DFT symbol sebolic addressing of DFT precompile output and multiplying each other in the specific constant of SC-FDMA symbol level, even when the order of DFT precompile and extension blocks changed, the value that is mapped to the signal of SC-FDMA symbol was identical.Therefore, can compile with channel, modulate, divide, expansion and the precompiler order of DFT carry out the signal handler for PUCCH form 3.Under these circumstances, can carry out division by a functional block processes and extension process.For example, modulation symbol can be expanded at SC-FDMA symbol level place, is divided into alternatively time slot simultaneously.As another example, when modulation symbol was divided into time slot, modulation symbol can be replicated to be fit to the size of extended code, and can be with the corresponding element that multiply by modulation symbol and extended code one by one.Therefore, the modulation symbol sequence that generates at each time slot is extended to a plurality of SC-FDMA symbols at SC-FDMA symbol level place.Thereafter, the complex symbol corresponding with each SC-FDMA symbol carries out the DFT precompile with the SC-FDMA symbolic unit.

Figure 29 C is different from Figure 29 A in the order of modulator and division device.Therefore, can be to compile and to divide at subframe level place combined channel and to carry out the signal handler that is used for PUCCH form 3 in the order of each time slot level place modulation, DFT precompile and expansion.

Figure 29 D is different from Figure 29 C in the order of DFT precompile device and extension blocks.As mentioned above, because the function of extension blocks equals to multiply by from the DFT symbol sebolic addressing of DFT precompile device output the specific constant of SC-FDMA symbol level, even so when the order of DFT precompile and extension blocks was changed, the value that is mapped to the signal of SC-FDMA symbol was identical.Therefore, by in subframe level place combined channel compiling with divide and can carry out signal handler for PUCCH form 3 in each time slot level place modulation.The modulation symbol sequence that generates at each time slot is extended to a plurality of SC-FDMA symbols at SC-FDMA symbol level place, and the modulation symbol sequence corresponding with each SC-FDMA symbol carries out the DFT precompile with the SC-FDMA symbolic unit.Under these circumstances, can carry out modulation treatment and extension process by a functional block.For example, when modulating the bit of having encoded, the place can directly expand the modulation symbol that generates in SC-FDMA symbol level.As another example, when modulating the bit of having encoded, modulation symbol is copied to be suitable for the size of extended code, and the element of modulation symbol and extended code can multiply each other correspondingly.

Figure 29 E illustrates the situation (normal CP) that is applied to the structure of PUCCH form 2 according to the PUCCH form 3 of the present embodiment, and Figure 29 F illustrates the situation (expansion CP) that will be applied to the structure of PUCCH form 2 according to the PUCCH form 3 of the present embodiment.The baseband signal handling procedure is equal to those that describe with respect to Figure 29 A to Figure 29 D.Owing to reusing the structure of the PUCCH form 2 of existing LTE, the UCI SC-FDMA symbol in PUCCH form 3 and the quantity/position of RS SC-FDMA symbol are different from Figure 29 A's.

Table 14 illustrates the position of the RS SC-FDMA symbol in the PUCCH form 3.Suppose in the situation that the quantity of the SC-FDMA symbol in the normal CP time slot is 7(index 0 to 6), and in the situation that the quantity of the SC-FDMA symbol in the expansion CP time slot is 6(index 0 to 5).

Table 14

Herein, RS can reuse the structure of existing LTE.For example, can use the cyclic shift definition RS sequence (referring to equation 1) of basic sequence.

Because SF=5 is so the multiplexing capacity of UCI data division is 5.According to cyclic shift interval △ _Shift ^PUCCHDetermine the multiplexing capacity of RS part.More especially, the multiplexing capacity of RS part is

For example, at △ _Shifi ^PUCCH=1, △ _Shift ^PUCCH=2 and △ _Shifi ^PUCCHIn=3 the situation, multiplexing capacity is respectively 12,6 and 4.In Figure 29 E to Figure 29 F, because SF=5, the multiplexing capacity of UCI data division is 5, and at △ _Shift ^PUCCHIn=3 the situation, the multiplexing capacity of RS part is 4.Therefore, whole multiplexing capacity is set to capacity 4 less in two capacity.

Figure 30 illustrates the structure of the PUCCH form 3 of the multiplexing capacity with increase.With reference to Figure 30, SC-FDMA symbol horizontal extension can be applied to the RS part in the time slot.Therefore, make the multiplexing capacity of RS part double.That is, though

Situation under, the multiplexing capacity of RS part becomes 8, and the multiplexing capacity of UCI data division is not lost.Orthogonal code covering for RS includes, but are not limited to, and walsh covers [y1 y2]=[1 1], [1-1] or linear transformation form (for example, [j j], [j-j], [1 j], [1-j] etc.).Y1 is applied to the RSSC-FDMA symbol in the time slot, and y2 is applied to the 2nd RS SC-FDMA symbol in the time slot.

Figure 31 illustrates the structure of another PUCCH form 3 of the multiplexing capacity with increase.If do not carry out the horizontal frequency hopping of time slot, then can additionally carry out expansion or cover (for example Walsh covers) with time slot unit, so that multiplexing capacity is double.In the situation that carry out the horizontal frequency hopping of time slot, cover if use Walsh with time slot unit, then owing to the difference between the channel condition of time slot causes orthogonality impaired.Time slot unit's extended code (for example, orthogonal code covers) for RS includes, but are not limited to [x1 x2]=[1 1], and the Walsh of [1-1] covers or its linear transformation form (for example, [j j] [j-j], [1 j] [1-j] etc.).X1 is applied to the first time slot and x2 is applied to the second time slot.Although execution time slot horizontal extension shown in the drawings (or cover) and then carry out the situation of expansion (or covering) at SC-FDMA symbol level place, can change sequentially.

With using equation the signal handler of PUCCH form 3 is described.For convenience's sake, suppose and for example use length 5OCC(, Figure 29 E to Figure 31).

At first, use the specific scramble sequence of UE to bit block b (0) ..., b (M _Bit-1) scrambling.Bit block b (0) ..., b (M _Bit-1) can with compiling bit b_0, the b_1 of Figure 29 A ..., b_N-1 is corresponding.Bit block b (0) ..., b (M _Bit-1) can comprise in ACK/NACK bit, CSI bit and the SR bit at least one.Can generate the bit block of scrambling according to following equation

Next, the configuration of UL transmission mode will be described.The transmission mode that is used for PUCCH can be divided into two kinds of patterns roughly.A kind of is that the single antenna transmissions pattern is the multi-antenna transmission pattern with another.The single antenna transmissions pattern refers to when UE transmission PUCCH by the method for single antenna transmissions signal or makes receiver (for example, BS) can identify method by the signal of single antenna transmissions.In the multi-antenna transmission pattern, UE can use virtualization scheme (for example, PVS, day line options, CDD etc.) simultaneously by a plurality of antenna transmission signals.Multi-antenna transmission pattern indication UE uses transmission diversity or MIMO scheme to transfer signals to BS by many antennas.As the transmit diversity scheme that use this moment, can usage space orthogonal resource transmission diversity (SORTD).In this manual, for convenience's sake, the multi-antenna transmission pattern is called as the SORTD pattern, except as otherwise noted.

Figure 32 illustrates the signal processing block/program for SORTD.Base program outside the eliminating multi-antenna transmission is processed equals the program with reference to Figure 29 to Figure 31 description.With reference to Figure 32, modulation symbol c_0 ..., c_23 carries out the DFT-precompile, and resource (for example, OC, PRB or its combination) transmission by giving based on each antenna port.In this example, although be that a plurality of antenna ports are carried out a DFT operation, can carry out the DFT operation based on every antenna port.In addition, although under the state that is replicated, transmit the precompiler symbol d_0 of DFT-by the 2nd OC/PRB ... d_23, but can transmit the precompiler symbol d_0 of DFT-by the 2nd OC/PRB ... the modification of d_23 (for example, conjugate complex number or scaling).For example, in order to guarantee at the orthogonality of passing through between the PUCCH signal of 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⁾] be possible.At this, numeral antenna port numbering or the value corresponding with it in the subscript.

Figure 33 is the schematic diagram of diagram SORTD operation.With reference to Figure 33, UE obtains first resource index and Secondary resource index (S3310).Resource index (perhaps resource value) indication PUCCH resource index (perhaps PUCCH resource value), and PUCCH form 3 resource indexs (perhaps PUCCH form 3 resource values) preferably.Step S3310 can comprise a plurality of steps of sequentially carrying out.The method of obtaining first resource index and Secondary resource index will be described in detail belows.Thereafter, UE uses the PUCCH resource corresponding with the first resource index to transmit PUCCH signal (S3320) by the first antenna (port).UE uses the PUCCH corresponding with the Secondary resource index to transmit PUCCH signal (S3330) by the second antenna (port).Execution in step S3320 and S3330 on identical subframe.

The PUCCH signal can comprise mixed automatic retransfer request-reply (HARQ-ACK).HARQ-ACK comprises the response (for example, ACK, NACK, DTX or NACK/DTX) to down link signal.If PUCCH comprises HARQ-ACK, although not shown, the program of Figure 33 further comprises the step of receiving downlink signal.The step of receiving downlink signal comprises the PDCCH and the PDSCH corresponding with PDCCH that receives for downlink scheduling.For PUCCH form 3 transmission, can receive among PDCCH and the PDSCH at least one at SCell.

Figure 32 to Figure 33 is described such as reference, and many antennas (port) transmission (for example, SORTD) requires quantitatively than the large orthogonal resource of stock number in single antenna (port) transmission.For example, 2Tx SORTD transmission requirement orthogonal resource, its quantity is the twice of the stock number in single antenna (port) transmission.Therefore, antenna (port) transmission mode and quantity at the multiplexing UE of the resource area that is used for PUCCH, that is, multiplexing capacity is associated.Therefore, BS needs to configure neatly antenna (port) transmission mode according to the quantity of the UE that communicates by letter with BS.For example, if the number of the UE that accepts by BS is little, many antennas (port) transmission mode that then can use a plurality of resources with respect to each UE configuration (for example, the SORTD pattern) and, if the quantity of the UE that accepts by BS is large, then can configure single antenna (port) transmission mode of using single resource.Can configure antenna (port) transmission mode of transmitting for PUCCH by the RRC signaling.In addition, can configure independently antenna (port) transmission mode based on every PUCCH form.

Hereinafter, the present invention proposes the whole bag of tricks with PUCCH form 3 Resources allocation (referring to the step S3310 of Figure 33) under the environment that uses a plurality of resources that are used for many antennas (port) transmission.For example, if 2Tx SORTD is applied to PUCCH form 3, then because need two orthogonal resources, so need the allocation rule of two orthogonal resources.

At first, description is required single antenna (port) transmission of an orthogonal resource.The resource distribution that is used for PUCCH form 3 distributes based on explicit resource.More specifically, UE can by higher level (for example, RRC) signaling be used for PUCCH form 3 by explicit allocation aforehand PUCCH resource value candidate (perhaps PUCCH resource value Candidate Set) (for example,

Thereafter, BS can be transferred to UE with ACK/NACK (A/N) resource indicator (ARI) (HARQ-ACK resource value), and UE can be identified for the PUCCH resource value by the actual PUCCH transmission of ARI

The PUCCH resource value

Be mapped to PUCCH resource (for example, OC or PRB).ARI can be used for directly indication, and which the PUCCH resource value candidate (perhaps PUCCH resource value Candidate Set) who is provided by higher level in advance will be provided.In realization, ARI can indicate (by higher level) to send the deviant of PUCCH resource value by signal.The PDSCH-scheduling PDCCH(SCell PDCCH that transmits at SCell) through-put power control (TPC) can be by again as ARI.The PDSCH-scheduling PDCCH(PCell PDCCH that transmits at PCell) TPC field can be used to the PUCCH power control of its original applications.In the situation that 3GPP version 10 because the PDSCH of PCell does not allow the intersection carrier dispatching from SCell, only receives PDSCH at PCell and can be equivalent to only receive PDCCH at PCell.

More specifically, if divide the PUCCH that is used in A/N resource by RRC in advance, then can followingly be identified for the resource of actual PUCCH transmission.

The PDCCH(that – is corresponding with the PDSCH on the SCell or with the corresponding SCell of PDSCH on PDCCH) indication uses the ARI(HARQ-ACK resource value) one of PUCCH resource by the RRC configuration.

If – do not detect the PDCCH(corresponding with the PDSCH on the SCell or with the corresponding SCell of PDSCH on PDCCH) and receive PDSCH at PCell, then any one in the following method is applicable:

Use is according to the implicit expression A/N PUCCH resource (that is, using the PUCCH form 1a/1b resource of the minimum CCE acquisition of configuration PDCCH) of existing 3GPP version 8.

The PDCCH(corresponding with the PDSCH on the PCell or with the corresponding PCell of PDSCH on PDCCH) indication uses the ARI(HARQ-ACK resource value) one of PUCCH resource by the RRC configuration.

The corresponding all PDCCH(of PDSCH on-supposition and the SCell or with the corresponding SCell of PDSCH on PDCCH) have an identical ARI(HARQ-ACK resource value).

The ARI(HARQ-ACK resource value) can have the X bit, and if the TPC field of SCell PDCCH be reused, then X can be 2.For convenience's sake, suppose X=2.

Hereinafter, if use description to use PUCCH form 3 control information transmissions then the resource allocation methods of supporting various antennas (port) transmission mode.

For example, UE can pass through four orthogonal resources that RRC signaling (for example, four RRC signals) is allocated for PUCCH form 3, for example, and the PUCCH resource value

With

In addition, UE can be assigned with a collection that is comprised of four PUCCH resource values

As a RRC signal.Thereafter, UE can detect the PDCCH signal and receive the PDSCH signal corresponding with it.Can receive in PDCCH signal and the PDSCH signal at least one by SCell.Thereafter, UE can be according to the ARI(HARQ-ACK resource value in the PDCCH signal) bit value be identified for the PUCCH resource value of actual PUCCH transmission

Determined PUCCH resource value is mapped to PUCCH resource (for example, OC or PRB).Use the PUCCH resource of mapping PUCCH resource value by network (for example, BS or relay nodes (RN) transmission UCI(for example is used for the HARQ-ACK of PDSCH).At said method shown in the table 16.

Table 16

Wherein, the HARQ-ACK indication is to the HARQ ACK/NACK/DTX response of downlink transmission block.HARQ ACK/NACK/DTX response comprises ACK, NACK, DTX and NACK/DTX.

If the TPC field transmission ARI(HARQ-ACK resource value of SCell PDCCH is used in supposition), only receive PDCCH at PCell if UE only receives PDSCH(at PCell), then nonrecognition ARI or the PUCCH resource value that is associated with ARI.Therefore, if event occurs, then can use the candidate mode (fall-back) of using existing 3GPP version 8/9PUCCH resource and version 8/9PUCCH form 1a/1b.

Next, transmission diversity (for example, SORTD) the method for a plurality of orthogonal resources that minute is used in will be described.For convenience's sake, suppose two orthogonal resources of use.

In the following description, the actual transmissions pattern of considering UE performance or UE can be distributed for the required resource (collection) of many antenna port transmission.For example, if UE supports many antenna port transmission, then BS can divide the Secondary resource (collection) that is used in many antenna port transmission and the first resource (collection) that is used for the single antenna port transmission in advance.Thereafter, UE can use first resource (collection) in single antenna port transmission pattern, and uses first resource (collection) and Secondary resource (collection) in many antenna ports transmission mode.In addition, BS can consider that the current transmission mode of UE comes the Secondary resource (collection) that minute is used in many antenna ports transmission.For example, BS can divide the Secondary resource (collection) that is used in UE after indication UE operates under many antenna ports transmission mode.That is, only configure after many antenna ports transmission mode under the state that distributes first resource (collection), UE can additionally be configured first resource (collection).

For example, UE can receive the assignment information that indication is used for a plurality of PUCCH resources of antenna port p0 basically, even and can additionally receive the assignment information that indication is used for a plurality of PUCCH resources of antenna port p1 when many antenna port transmission are possible or configure many antenna ports transmission mode.

Under these circumstances, UE can pass through eight orthogonal resources that RRC signal (for example, eight RRC signals) is allocated for PUCCH form 3, for example, and the PUCCH resource value

And In addition, UE can be assigned with a collection that is comprised of eight PUCCH resource values by a RRC signal Thereafter, UE can detect PDCCH signal and the PDSCH signal corresponding with it.Can receive in PDCCH signal and the PDSCH signal at least one by SCell.Thereafter, UE can be according to the ARI(HARQ-ACK resource value in the PDCCH signal) bit value be identified for the PUCCH resource value of actual PUCCH transmission P represents antenna port numbering or the value corresponding with it.Determined PUCCH resource value is mapped to PUCCH resource (for example, OC or PRB).Use is mapped with the PUCCH resource of PUCCH resource value and for example passes through network (for example, BS or via node (RN)) transmission UCI(, is used for the HARQ-ACK of PDSCH).

In many antenna ports transmission mode, an ARI is used to indicate a plurality of PUCCH resource values.Be mapped to PUCCH resource for separately antenna port by a plurality of PUCCH resource values of ARI indication.Therefore, be single antenna port mode or many antenna ports pattern according to the antenna port transmission mode, ARI can indicate one or more PUCCH resource value.In aforesaid method shown in the table 17.

Table 17

As another example, UE can be distributed four orthogonal resources (for example, PUCCH resource value) by the RRC signaling as follows based on every antenna port.Thereafter, UE can detect the PDCCH signal and receive the PDSCH signal corresponding with it.Can receive in PDCCH signal and the PDSCH signal at least one by SCell.Thereafter, UE can be according to the ARI(HARQ-ACK resource value in the PDCCH signal) bit value determine the final PUCCH resource value that will use based on every antenna port Determined PUCCH resource value is mapped to the PUCCH resource (for example, OC or PRB) for each antenna port.P marker antenna port numbering or the value corresponding with it.In the method shown in the table 18.

For example be used for antenna port p0(, p0=0)

For example be used for antenna port p1(, p1=1).

But unrestricted, as mentioned above, UE can receive the assignment information that indication is used for a plurality of PUCCH of antenna port p0 basically, and and if only if the transmission of many antenna ports be possible or can additionally receive the assignment information that indication is used for a plurality of PUCCH resources of antenna port p1 during configuration multi-antenna transmission pattern.

Table 18

If the transmission of many antenna ports is possible or configures many antenna ports transmission mode, then UE can be allocated for basically by a RRC signal four orthogonal resources of single antenna port transmission, for example, and the PUCCH resource value And can be allocated for by a RRC signal eight orthogonal resources of two antenna ports, for example, the PUCCH resource value

UE can determine the final PUCCH resource value that will use according to the bit value of ARI based on every antenna port

With the PUCCH resource corresponding with it.At said method shown in the table 19.

Table 19

Table 17 illustrates part p=p0 for the distribution of the PUCCH resource value of many antenna ports to 19 and is configured to equal situation in the single antenna port.That is, suppose nested structure at table 17 in to 19.Therefore, a common block list can support single antenna port transmission and many antenna ports to transmit both.

Reference table 18 will be described nested structure in further detail.In nested structure, can use a common block list.Table 20 illustrates the common block list for single antenna port transmission pattern and many antenna ports transmission mode.

Table 20

If UE is configured to transmit the single antenna port transmission pattern that is associated with PUCCH, then can come analytical table 20 such as table 21.Therefore, if UE is configured to single antenna port transmission pattern, the PUCCH resource value of then indicating by ARI

Finally be mapped to for single antenna port (for example, p0) a PUCCH resource

Table 21

If UE is configured to transmit the many antenna ports transmission mode that is associated with PUCCH, then can come analytical table 20 such as table 22.Therefore, if UE is configured to many antenna ports transmission mode, the PUCCH resource value of then indicating by ARI Finally be mapped to a plurality of PUCCH resources for a plurality of antenna ports (for example, p0 and p1)

With

Table 22

To describe as another example of dividing many (for example, two) the individual orthogonal resource that is used in transmission diversity, that is, and SORTD.For example, suppose by RRC signal (for example, four RRC signals) UE to be allocated for four orthogonal resources of PUCCH form 3, for example, the PUCCH resource value

And

Alternatively, can suppose by a RRC signal UE and be assigned with a collection that is formed by four resource values

As mentioned above, UE can determine the final PUCCH resource that will use according to the bit value of ARI based on every antenna port

Based on top hypothesis, according to this example, four PUCCH resource values can be divided in groups

And group Two groups.Under these circumstances, a bit of the forward part of ARI bit and rear section can be used to indicate the resource for separately group.For example, suppose that ARI forms (each among b0 and the b1 is 0 or 1) by b0 and b1.Under these circumstances, which PUCCH resource value the b0 indication uses in group 0, and which PUCCH resource value the b1 indication uses in group 1.PUCCH resource (for example, OC or PRB) for antenna port p0 can be mapped to from organizing 0 the PUCCH resource value of selecting, and PUCCH resource (for example, OC or PRB) for antenna port p1 can be mapped to from organizing the resource of selecting 1.

At said method shown in the table 23.Although this method can be applicable to distribute four PUCCH resource values by the RRC signaling

And Situation, but this method can be applicable to use the situation of more orthogonal resources.

Table 23

Table 23 illustrates every independent antenna and receives (in the situation that 2Tx, four altogether) signal by two RRC signals, and each bit indication of ARI is used for the situation of the resource of each antenna port.Table 24 illustrates antenna port p0 is distributed

And antenna port p1 is distributed

Situation.

Table 24

As another example of the present invention, the method for the down link assignment indexing in the situation of TDD CA will be described in.DAI is the value that obtains by the PDCCH that is scheduled of counting in time domain, and is extendible for territory, the residential quarter among the CA (perhaps CC).In the situation that PUCCH form 3, because the DAI value is optional, so can use DAI in the present invention.

For example, use ARI can distribute/be identified for PUCCH form 3 resources of first day line cap (p=p0), and can use DAI to distribute/be identified for the PUCCH format resource of second day line cap (p=p1).The PDCCH of Serving cell can be restricted to and have identical DAI value, think in the situation of the PDCCH of at least one Serving cell failure and prepare.If only dispatch PDSCH at PCell, then UE can ignore the DAI value of the PCellPDCCH corresponding with PDSCH, gets back to the single antenna port mode, and transmission PUCCH.

For convenience's sake, suppose by RRC signaling UE and distributed in advance four orthogonal resources, for example, the PUCCH resource value

And

Comprise ARI=[00 if supposition UE receives thereafter ,] and DAI=[10] the PDCCH signal.

For example be used for antenna port p0(, p0=0)

For example be used for antenna port p1(, p1=1)

At said method shown in the table 25.

Table 25

In addition, identical method can be applicable to following situation,, is distributed in advance eight orthogonal resources by RRC signaling UE that is, for example, and the PUCCH resource value

For example, the ARI value 00,01,10 and 11 that is used for antenna port 0 is indicated respectively

And

And the DAI value 00,01,10 and 11 that is used for antenna port 1 is indicated respectively

And

As another example, can be by four orthogonal resources of following distribution by RRC signaling UE based on every antenna port.

For example be used for antenna port p0(, p0=0)

For example be used for antenna port p1(, p1=1)

At this moment, ARI value 00,01,10 and 11 is indicated respectively

And

And DAI value 00,01,10 and 11 is indicated respectively
