Embodiment

Following technology can be utilized in the various wireless access systems of such as code division multiple access (CDMA) system, frequency division multiple access (FDMA) system, time division multiple access (TDMA) system, OFDM (OFDMA) system or single-carrier frequency division multiple access (SC-FDMA) system.Cdma system may be embodied as the wireless technology of such as general land wireless access (UTRA) or CDMA2000.Tdma system may be implemented as the wireless technology of the GSM evolution (EDGE) of such as global system for mobile communications (GSM)/general packet radio service (GPRS)/enhancing data rate.OFDMA system may be implemented as such as IEEE802.11(Wi-Fi), IEEE802.16(WiMAX), the UTRA of IEEE802-20 or E-UTRA(evolution) wireless technology.UTRA system is a part of Universal Mobile Telecommunications System (UMTS).Third generation partner program Long Term Evolution (3GPP LTE) communication system is the UMTS of E-UMTS(evolution) a part, it adopts OFDMA system in the downlink and adopts SC-FDMA system in the uplink.LTE-A(is senior) be the evolution version of 3GPP LTE.In order to illustrate description, 3GPP LTE/LTE-A will be concentrated on, but technical scope of the present invention is not limited thereto.

In a wireless communication system, subscriber equipment (UE) receives information from base station (BS) in down link (DL), and in up link (UL) by information transmission to BS.Between BS and UE, the information of transmission or reception comprises data and various control information, and there is various physical channel according to the kind/purposes of the information transmitted or receive.

Fig. 1 illustrates the view for the physical channel of third generation partner program (3GPP) Long Term Evolution (LTE) system (it is an example of mobile communication system) and the general signal transmission method of this physical channel of use.

When switching on power as UE or reenter community as UE, in step S101, UE performs such as synchronous with BS search of initial zone operation.For search of initial zone operation, UE can receive primary synchronization channel (P-SCH) and auxiliary synchronization channel (S-SCH) from BS, and to make, execution and BS's is synchronous, and obtains the information of such as community ID.Thereafter, UE can receive Physical Broadcast Channel from BS, and obtains the broadcast message in community.Meanwhile, UE can in search of initial zone step receiving downlink reference signal (DL RS), and confirm downlink channel status.

In step s 102, the UE completing search of initial zone can receive physical downlink control channel (PDCCH) and the physical down link sharing channel corresponding with PDCCH (PDSCH), and obtains more detailed system information.

Thereafter, UE can perform random access procedure in step S103 to S106, so that complete the access to eNB.For random access procedure, UE via Physical Random Access Channel (PRACH) transmission preamble (S103), and can receive in response to leading message (S104) via PDCCH and the PDSCH corresponding with PDCCH.In the Stochastic accessing based on competition, can perform contention resolved process, this contention resolved process comprises the transmission (S105) of additional PRACH and the reception (S106) of PDCCH and PDSCH corresponding thereto.

Then the UE performing said process can receive PDCCH/PDSCH(S107), and transmitting physical uplink shared channel (PUSCH)/physical uplink control channel (PUCCH) (S108), as general uplink/downlink signals transmission.The control information being transferred to BS from UE is collectively referred to as uplink control information (UCI).UCI comprises hybrid automatic repeat-request acknowledgement/non-acknowledgement (HARQ ACK/NACK), dispatch request (SR), CQI (CQI), precoding matrix indicators (PMI), order designator (RI) etc.Usually UCI is transmitted via PUCCH.But, at the same time when control information transmission and business datum, can via PUSCH transmission UCI.Can according to network request/instruction via PUSCH aperiodic transmit UCI.

Fig. 2 exemplarily illustrates wireless frame structure.In cellular orthogonal frequency division multiplexing (OFDM) radio packet communication system, in subframe unit, perform uplink/downlink data packet transfer.A subframe is defined as the predetermined time interval comprising multiple OFDM symbol.The support of 3GPP LTE standard can be applicable to the Class1 wireless frame structure of Frequency Division Duplexing (FDD) (FDD) and can be applicable to type 2 wireless frame structure of time division duplex (TDD).

Fig. 2 (a) is the figure of the structure that Class1 radio frames is shown.Downlink wireless frame comprises 10 subframes, and a subframe comprises two time slots in the time domain.The time required for transmission subframe is limited with Transmission Time Interval (TTI).Such as, subframe can have the length of 1 millisecond, and time slot can have the length of 0.5 millisecond.A time slot can comprise multiple OFDM symbol in the time domain and comprise multiple Resource Block (RB) in a frequency domain.Because 3GPP LTE system uses OFDMA in the downlink, OFDM symbol indicates a symbol duration.OFDM symbol can be called as SC-FDMA symbol or symbol duration.RB is resource allocation unit and comprises multiple continuous subcarrier in one time slot.

The quantity of the OFDM symbol comprised in one time slot can change according to the configuration of Cyclic Prefix (CP).CP comprises expansion CP and normal CP.Such as, if configure OFDM symbol by normal CP, then the quantity of the OFDM symbol comprised in one time slot can be seven.If configure OFDM symbol by expansion CP, the length of an OFDM symbol is increased, and the quantity of the OFDM symbol comprised in one time slot is less than the quantity of the OFDM symbol when normal CP.When expanding CP, such as, the quantity of the OFDM symbol comprised in one time slot can be six.Such as, if channel status is unstable, if subscriber equipment (UE) high-speed mobile, then can use expansion CP so that reduce the interference between symbol further.

When using normal CP, because a time slot comprises seven OFDM symbol, so a subframe comprises 14 OFDM symbol.Meanwhile, the first two of each subframe or three OFDM symbol can be assigned to physical downlink control channel (PDCCH), and remaining OFDM symbol can be assigned to physical down link sharing channel (PDSCH).

The structure of type 2 radio frames shown in Fig. 2 (b).Type 2 radio frames comprises two fields, and each field is wherein made up of five subframes, down link pilot timeslot (DwPTS), protective time slot (GP) and uplink pilot time slot (UpPTS), and one of them subframe is made up of two time slots.DwPTS is for performing search of initial zone, synchronous or channel estimating.UpPTS is synchronous for the ul transmissions of the channel estimating and subscriber equipment (UE) that perform base station.Protective time slot (GP), between up link and down link, makes the interference eliminated because the multidiameter of down link signal produces in the uplink.

The structure of radio frames is only exemplary.Therefore, the quantity of the time slot can change the quantity of the subframe comprised in radio frames in a different manner, comprising in subframe or the quantity of symbol comprised in a slot.

Fig. 3 a illustrates the view of the signal processing at UE place transmission UL signal.

In order to transmit UL signal, the signal that the scrambling module 210 of UE can use the specific scrambled signals of UE to carry out scrambling to be transmitted.Scrambled signals being input to modulation mapper 202, making kind and/or channel status according to being transmitted signal are modulated into complex symbol by two-phase PSK (BPSK), quarternary phase-shift keying (QPSK) (QPSK), 16-quadrature amplitude modulation (QAM) or 64-QAM scheme.Thereafter, process modulated complex symbol by conversion precoder 203 and be entered into resource element mapper 204.Complex symbol can be mapped to time-frequency resources element by resource element mapper 204.Can via SC-FDMA signal generator 205 and antenna by processed Signal transmissions to BS.

Fig. 3 b is the figure of the signal processing at BS communicating downlink (DL) signal.

In 3GPP LTE system, BS can transmit one or more code word in the downlink.Therefore, one or more code word can be processed to configure complex symbol by scrambling module 301 and modulation mapper 302, transmits similar with the UL of Fig. 3 a.Thereafter, by layer mapper 303, complex symbol can be mapped to multiple layer, and each layer can be multiplied by pre-coding matrix 304 and can be assigned to each transmit antenna.The processed signal that will transmit respectively via antenna can be mapped to time-frequency resources element by resource element mapper 305, and can be transmitted respectively via OFDMA signal generator 306 and antenna.

In a wireless communication system, when UE in the uplink signal transmission, compared with the situation of BS signal transmission in the downlink, peak-to-average force ratio (PAPR) may be more problematic.Therefore, as with reference to figure 2 and 3 above-described, OFDMA scheme be used for transmitted downlink signal, and SC-FDMA scheme be used for transmitting uplink signals.

Fig. 4 is the figure explaining SC-FDMA scheme and OFDMA scheme.In a 3 gpp system, use OFDMA scheme in the downlink and use SC-FDMA in the uplink.

With reference to figure 4, UE for UL Signal transmissions and the BS something in common for DL Signal transmissions are, comprise leaf inverse transformation (IDFT) module 404 in serial-parallel converter 401, subcarrier mapper 403, M point discrete Fourier, parallel-serial converter 405 and Cyclic Prefix (CP) and add module 406.N point DFT module 402 is also comprised for using the UE of SC-FDMA scheme transmission signal.N point DFT module 402 partly offsets the IDFT process impact of (offset) M point IDFT module 404, makes the signal be transmitted have single-carrier property.

Fig. 5 is the figure explaining the signal map scheme met in a frequency domain in the frequency domain of single-carrier property.Fig. 5 (a) illustrates local mapping scheme, and Fig. 5 (b) illustrates distribution map scheme.

Will describe now the SC-FDMA scheme of sub-clustering, it is the modification of SC-FDMA scheme.In the SC-FDMA scheme of sub-clustering, DFT process exports sampling and be divided into subgroup (sub-group) in subcarrier mapping process, and by discontinuous mapping in frequency domain (or sub-carrier domains).

Fig. 6 illustrates figure DFT process output sampling being mapped to the signal processing of single carrier wave in the SC-FDMA scheme of sub-clustering.Fig. 7 and Fig. 8 illustrates figure DFT process output sampling being mapped to the signal processing of multiple carrier wave in the SC-FDMA scheme of sub-clustering.Fig. 6 illustrates the SC-FDMA(intra-carrier clustered SC-FDMA of sub-clustering in application carrier wave) example of scheme, and Fig. 7 and Fig. 8 illustrates the SC-FDMA(inter-carrierclustered SC-FDMA of application intercarrier sub-clustering) example of scheme.Fig. 7 is generated signal by single IFFT block and is arranged the situation of the sub-carrier separation between continuous component carrier under the state of distributing component carrier in a frequency domain is continuously shown, and Fig. 8 discontinuous distribution component carrier is in a frequency domain shown state under to be generated the situation of signal by multiple IFFT block.

Fig. 9 is the figure of the signal processing illustrated in the SC-FDMA scheme of segmentation.

In the SC-FDMA scheme of segmentation, IFFT corresponding with the DFT of given number on number is employed, and makes DFT and IFFT be corresponding one to one, and the DFT of conventional SC-FDMA scheme expands and the frequency sub-carrier mapping configuration of IFFT is expanded.Therefore, the SC-FDMA scheme of segmentation is also referred to as NxSC-FDMA or NxDFT-s-OFDMA scheme.In the present invention, generic term " SC-FDMA of segmentation " is used.With reference to figure 9, the SC-FDMA design features of segmentation is, the modulation symbol of whole time domain be grouped into N(N be greater than 1 integer) group, and perform DFT process to organize based on unit, so that relax (relax) single-carrier property.

Figure 10 is the figure of the structure that UL subframe is shown.

Multiple time slot (such as, two) is comprised with reference to Figure 10, UL subframe.Each time slot comprises SC-FDMA symbol, and its quantity changes according to the length of CP.Such as, when normal CP, time slot can comprise seven SC-FDMA symbols.UL subframe is divided into data area and control area.Data area comprises PUSCH, and for transmitting the data-signal of such as voice.Control area comprises PUCCH and for control information transmission.PUCCH is included in the RB at two ends place frequency axis being positioned at data area to (such as, m=0,1,2,3), and between time slot frequency hopping.UL control information (that is, UCI) comprises HARQ ACK/NACK, channel quality information (CQI), precoding matrix indicators (PMI) and order designator (RI).

Figure 11 is the figure of diagram for the signal processing of transmission of reference signals (RS) in the uplink.As shown in Figure 11, data are converted into frequency-region signal by DFT precoder, and stand frequency map and IFFT, and are transmitted.On the contrary, RS is not by DFT precoder.More specifically, RS sequence is directly generated (step S11) in a frequency domain, stands local and maps process (step S12), stand IFFT(step S13), stand CP additional treatments (step S14), and be transmitted.

Figure 15 illustrates the PUCCH format 2/2a/2b when normal CP.Figure 16 illustrates the PUCCH format 2/2a/2b when expanding CP.With reference to Figure 15 and Figure 16, when normal CP, except RS symbol, a subframe comprises 10 QPSK data symbols.Each QPSK symbol is expanded by CS in a frequency domain, and is then mapped to corresponding SC-FDMA symbol.SC-FDMA symbol rank CS frequency hopping can be employed, so that make presence of intercell interference randomization.CS can be used to pass through the multiplexing RS of CDM.Such as, if suppose that the quantity of available CS is 12 or 6, then can in identical PRB multiplexing 12 or 6 UE.Such as, in PUCCH format 1/1a/1b and 2/2a/2b, can multiplexing multiple UE by CS+OC+PRB and CS+PRB.

The combination of CQI, PMI, RI and CQI and ACK/NACK can be transmitted by PUCCH format 2/2a/2b.Reed-Muller (Reed Muller) (RM) chnnel coding can be applied.

Such as, in LTE system, the chnnel coding for UL CQI is described as follows.(20, A) RM code is used to carry out channel-coded bit sequence a ₀, a ₁, a ₂, a ₃..., a _a-1table 10 illustrates the basic sequence for (20, A) code.A ₀and a _a-1represent highest significant position (MSB) and least significant bit (LSB) respectively.When expanding CP, maximum information amount of bits is 11, except the situation that CQI and ACK/NACK is transmitted simultaneously.After bit sequence is encoded into 20 bits by use RM code, QPSK modulation can be applied.QPSK modulation before, can scrambling by the bit of encoding.

Figure 19 illustrates that PRB distributes.As shown in Figure 19, PRB may be used for the PUCCH transmission in time slot ns.

Multicarrier system or carrier aggregation system refer in order to broadband is supported, polymerization and utilization have the system of multiple carrier waves of the bandwidth being less than target bandwidth.In order to the backward compatibility with existing system, when multiple carrier waves with the bandwidth being less than target bandwidth are polymerized, the bandwidth of the carrier wave of polymerization can be limited to the bandwidth used in existing system.Such as, existing LTE system can support the bandwidth of 1.4,3,5,10,15 and 20MHz, and from the senior LTE(LTE-A of LTE system evolution) the system bandwidth that can only use LTE system to support supports to be greater than the bandwidth of 20MHz.Alternatively, the bandwidth no matter used in existing system, can define new bandwidth, makes to support CA.Multicarrier interchangeably can use with CA and aggregated bandwidth.CA comprises continuous CA and discontinuous CA.

Figure 20 is the concept map of the management of downlink component carrier in BS, and Figure 21 is the concept map of the management of uplink component carrier in UE.Conveniently explain, assuming that higher level is MAC layer in Figure 20 and Figure 21.

Figure 22 is the concept map that MAC layer manages the situation of multiple carrier wave in BS.Figure 23 is the concept map that MAC layer manages the situation of multiple carrier wave in UE.

With reference to Figure 22 and Figure 23, a MAC layer manages one or more frequency carrier to make perform transmission and receive.Because the frequency carrier managed by a MAC layer does not need to be mutual continuous print, so resource management is flexibly.In Figure 22 and Figure 23, for convenience's sake, physics (PHY) layer means one-component carrier wave.PHY layer is unnecessary means independently radio frequency (RF) equipment.Usually, one independently RF equipment mean a PHY layer, but the present invention is not limited thereto.A RF equipment can comprise several PHY layer.

Figure 24 is the concept map that multiple MAC layer manages the situation of multiple carrier wave in BS.Figure 25 is the concept map that multiple MAC layer manages the situation of multiple carrier wave in UE, and Figure 26 is another concept map that multiple MAC layer manages the situation of multiple carrier wave in BS, and Figure 27 is another concept map that multiple MAC layer manages the situation of multiple carrier wave in UE.

Except except the structure shown in Figure 22 and Figure 23, several MAC layer can control several carrier wave, as shown in Figure 24 to Figure 27.

Each MAC layer can control each carrier wave one to one accordingly, as as shown in Figure 24 and Figure 25, and each carrier wave can be controlled accordingly one to one for each MAC layer of some carrier waves, and one or more carrier wave can be controlled, as shown in Figure 26 and Figure 27 for remaining carrier wave MAC layer.

System comprises the multiple carrier waves of such as carrier wave to N number of carrier wave, and carrier wave can be continuous print or discrete, no matter UL/DL.TDD system is configured to management many (N) individual carrier wave in DL and UL transmission.FDD system is configured to make in UL and DL, use multiple carrier wave.When FDD system, the bandwidth of the quantity and/or carrier wave that can be supported in the carrier wave be polymerized in UL and DL is different asymmetric CA.

When the quantity of the component carrier of the polymerization in UL and DL is identical, all component carriers can be configured, make it possible to and existing system back compatible.But, do not get rid of from the present invention and do not consider compatible component carrier.

Hereinafter, for convenience of description, assuming that when transmitting PDCCH by DL component carrier #0, the PDSCH corresponding with PDCCH is transmitted by by DL component carrier #0.But, can apply across carrier wave (cross-carrier) scheduling, and can by another DL component carrier transmission PDSCH.Term " component carrier " can be replaced by another equivalent terms (such as, community).

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

Figure 28 illustrates the figure of the asymmetric CA that 5 DL CC and UL CC is linked.Asymmetric CA can be set from the viewpoint of UCI transmission.That is, the DLCC-UL CC that can differently arrange for UCI links and DL CC-UL CC for data links.For convenience's sake, if a supposition DL CC can transmit maximum two code words, then the number of UL ACK/NACK bit is at least two.Under these circumstances, in order to be transmitted the ACK/NACK of the data being used for being received by 5 DL CC by a UL CC, the ACK/NACK of at least 10 bits is necessary.In order to support the DTX state of each DL CC, for ACK/NACK transmission at least 12 bits (=5 ⁵=3125=11.61 bit) be necessary.Because the ACK/NACK of maximum 2 bits can be transmitted with existing PUCCH format 1a/1b, so such structure can not the ACK/NACK information of transmitting extended.For convenience's sake, although describe the example of the amount increasing UCI information due to CA, due to the existence etc. of the backhaul subframe in the increase of antenna amount, TDD system and delay system, the amount of UCI information may be increased.Similar to ACK/NACK, when transmitting by a UL CC control information be associated with multiple DL CC, the amount of the control information that be transmitted increases.Such as, when UL anchor (anchor) (or main) CC transmission must be passed through be used for the CQI of multiple DL CC, CQI payload may be increased.

Main for DL CC can be defined as the DL CC that the main CC with UL links.Link comprises implicit expression and explicit link.In LTE, a DL CC and UL CC is by pairing (inherentlypaired) naturally.Such as, matched by LTE, the DL CC linked with the main CC of UL can be called as the main CC of DL.This can be considered to hiding link.Explicit link refers to the link of network configured in advance and explicit link is sent with signal by RRC etc.In explicit link, the DL CC matched with the main CC of UL can be called as main DL CC.UL master's (or anchor) CC can be the UL CC wherein transmitting PUCCH.Alternatively, the main CC of UL can be wherein by the UL CC of PUCCH or PUSCH transmission UCI.The main CC of DL can be configured by higher level signaling.The main CC of DL can be that wherein UE performs the DL CC of initial access.DL CC except the main CC of DL can be called as the auxiliary CC of UL.Similarly, the UL CC except the main CC of UL can be called as the auxiliary CC of UL.

LTE-A uses the concept of community so that managing radio resources.By the combination that cell definitions is down-chain resource and uplink resource, the component and uplink resource is not absolutely necessary.Therefore, community can only be made up of down-chain resource or can be made up of the combination of down-chain resource and uplink resource.If CA is supported, then the link between down-chain resource carrier frequency (or DL CC) and uplink resource carrier frequency (or UL CC) can be indicated by system information.Main plot (PCell) can be called with the community (or PCC) that main frequency (primary frequency) operates, and auxiliary community (SCell) can be called with the community (or SCC) that quenching frequency (secondaryfrequency) operates.DL CC and UL CC can be called DL community and UL community.In addition, anchor (or main) DL CC and anchor (or main) UL CC can be called as DL PCell and UL PCell respectively.PCell is used to perform the initial connection establishment process of UE or connection re-establishes process.PCell can indicate community indicated in hand-off process.SCell can be configured after execution RRC connection establishment, and SCell may be used for providing other Radio Resource.PCell and SCell can be referred to as Serving cell.Therefore, be in RRC_ connection (RRC_CONNECTED) state at UE but when not being configured with CA or not supporting CA, only comprise the unique Serving cell existence of PCell.On the contrary, when UE is in RRC_CONNECTED state and is configured with CA, there is one or more Serving cell, and each Serving cell comprises PCell and all SCell.For CA, except the PCell initially configured in connection establishment process, one or more SCell that network can also be configured to support the UE of CA and configure after starting initial security and activating process.

Only can define DL-UL pairing in fdd.Because TDD uses same frequency, so DL-UL pairing can not be defined.Can determine that DL-UL links by UL E-UTRA Absolute Radio Frequency Channel Number (EARFCN) information of SIB2 from UL link.Such as, between initial access periods, DL-UL link can be obtained by SIB2 decoding, not so, can be obtained by RRC signaling.Therefore, only SIB2 link can exist, and other DL-UL pairing is not defined significantly.Such as, in the 5DL:1UL structure of Figure 28, DL CC#0 and UL CC#0 has SIB2 linking relationship, and remaining DL CC can with to other UL CC that UE configures, not there is relation.

In order to support the scene of such as Figure 28, new departure is necessary.Hereinafter, the PUCCH format for the feedback (such as, multiple A/N bit) of UCI in the communication system supporting carrier aggregation is called as CA PUCCH format (or PUCCH format 3).Such as, PUCCH format 3 is used to transmit and PDSCH(or PDCCH arrived at multiple DL cell receiver) corresponding A/N information (possibly, comprising DTX state).

Figure 29 A to Figure 29 F illustrates structure according to the PUCCH format 3 of the present embodiment and signal processing thereof.

Figure 29 A illustrates and is applied to the normal CP of PUCCH format 1(according to the PUCCH format of the present embodiment) the situation of structure.With reference to figure 29A, channel coding blocks to information bit a_0, a_1 ..., a_M-1(such as, multiple ACK/NACK bit) carry out chnnel coding, and generate coded-bit (encoded bit or the bit of encoding) (or code word) b_0, b_1 ..., b_N-1.M represents the size of information bit, and the size of N presentation code bit.Information bit comprises UCI, such as, for the multiple ACK/NACK bits of multiple data (or PDSCH) received by multiple DL CC.Regardless of the kind/quantity/size of the UCI of configuration information bit, information bit a_0, a_1 ..., and a_M-1 be jointly encoded.Such as, if information bit comprises the multiple ACK/NACK bits for multiple DL CC, then do not perform chnnel coding relative to each DL CC or each ACK/NACK bit, but perform chnnel coding relative to whole bit information.Therefore single code word is generated.Chnnel coding can include, but are not limited to simple repetition, simplex coding (simplex coding), Reed-Muller (RM) coding, punching RM coding, sting tail convolutional encoding (TBCC), low-density checksum (LDPC) and turbo coding.Although not shown in figures, consider modulation order and stock number, coded-bit can by rate-matched.Rate-matched function can be included in channel coding blocks or can use independent functional block to perform.Such as, channel coding blocks can be encoded relative to multiple control information execution (32,0) RM, to make to obtain single code word and to perform circular buffering rate-matched.

Modulators modulate is by bit b_0, b_1 of encoding ..., and b_N-1, and generate modulation symbol c_0, c_1 ..., and c_L-1.L represents the size of modulation symbol.Modulator approach is performed by the amplitude and phase place that change the signal transmitted.Such as, modulator approach comprise n phase phase shift keying (n-PSK and n quadrature amplitude modulation (qam) (and n be greater than or equal to 2 integer).More specifically, modulator approach can comprise two-phase PSK(BPSK), four phase PSK(QPSK), 8-PSK, QAM, 16-QAM, 64-QAM etc.

Divider is by modulation symbol c_0, c_1 ..., and c_L-1 be divided into time slot.Do not limit order/pattern/method modulation symbol being divided into time slot particularly.Such as, modulation symbol is sequentially divided into time slot (local type) by divider from head.In this case, as directed, modulation symbol c_0, c_1 ..., c_L/2-1 time slot 0 can be divided into, and modulation symbol c_L/2, c_L/2+1 ..., c_L-1 time slot 1 can be divided into.When being divided into time slot, modulation symbol can be interleaved (or arrangement).Such as, the modulation symbol of even-numbered time slot 0 can be divided into, and the modulation symbol of odd-numbered time slot 1 can be divided into.Modulation treatment can be changed and divide the order processed.Be alternative in and different coded-bits is divided into time slot, identical coded-bit can be configured to repeat with time slot units.Under these circumstances, divider can be omitted.

DFT precoder performs DFT precoding (such as, 12 DFT) relative to the modulation symbol being divided into time slot, so that generate single carrier waveform.With reference to accompanying drawing, be divided into the modulation symbol c_0 of time slot 0, c_1 ... and c_L/2-1 and be precoded into DFT symbol d_0, d_1 ... and d_L/2-1 by DFT, and be divided into the modulation symbol c_L/2 of time slot 1, c_L/2+1 ... and c_L-1 and be precoded into DFT symbol d_L/2, d_L/2+1 ... and d_L-1 by DFT.DFT precoding can be replaced by another linear operation (such as, Walsh precoding).DFT precoder can be replaced by CAZAC modulator.CAZAC modulators modulate be divided into the time slot with corresponding sequence 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_1/2-1 and d_L/2, d_L/2+1 ..., and d_L-1.Such as, CAZAC modulator comprises the sequence of CAZAC sequence or (CG) 1RB for LTE Practical computer teaching.Such as, if LTE CG sequence be r_0 ..., and r_L/2-1, then CAZAC modulation symbol can be d_n=c_n*r_n or d_n=conj (c_n) * r_n.

Extension blocks stands the signal of DFT in SC-FDMA symbol rank (time domain) expansion.Extended code (sequence) is used to perform the expansion of other time domain of SC-FDMA symbol level.Extended code comprises quasiorthogonal code and orthogonal code.Quasiorthogonal code includes, but are not limited to pseudo noise (PN) code.Orthogonal code includes, but are not limited to Walsh code and DFT code.Although in order to the simple orthorhombic code described in the present invention is described to the representative example of extended code, orthogonal code is only exemplary and can be replaced by quasiorthogonal code.The maximum of extended code size (or spreading factor (SF)) is limited by the quantity of the SC-FDMA symbol for control information transmission.Such as, when four SC-FDMA symbols be used in one time slot control information transmission, can use in each time slot there is length 4 (standard) orthogonal code w0, w1, w2 and w3.SF means the degree of expansion of control information, and is associated with the multiplexing rank (order) of UE or the multiplexing rank of antenna.SF can become 1,2,3,4 according to the demand of system ..., and can between BS and UE predefined, or UE can be notified to by DCI or RRC signaling.Such as, when one of SC-FDMA symbol for control information be perforated so that transmitting SRS, the extended code with the SF value (such as, SF=3 instead of SR=4) of minimizing can be applied to the control information of time slot.

The signal generated by said process is mapped to the subcarrier in PRB, stands IFFT, and is converted into time-domain signal.Time-domain signal is attached to CP, and the SC-FDMA symbol generated is transmitted by by RF level (RF stage).

Assuming that be transmitted for the ACK/NACK of 5 DL CC, each process will be described in detail.When each DL CC can transmit two PDSCH, if comprise DTX state, then the number of ACK/NACK bit can be 12.Consider QPSK modulation and SF=4 temporal extension, coded block size (after rate matching) can be 48 bits.The bit modulation of coding can be become 24 QPSK symbols, and 12 symbols in the QPSK symbol generated are divided into each time slot.In each time slot, by 12 DFT operations, 12 QPSK symbol transition are become 12 DFT symbols.In each time slot, 12 DFT symbols are used the extended code with SF=4 in the time domain and are extended to four SC-FDMA symbols, and mapped.Because transmit 12 bits, so encoding rate is 0.0625(=12/192 by [2 bit * 12 subcarrier+8SC-FDMA symbol]).When SF=4, every 1PRB can multiplexing maximum four UE.

The signal processing described with reference to figure 29A is only exemplary, and the signal being mapped to PRB in Figure 29 A can use the signal processing of various equivalence and obtain.The signal processing being equivalent to Figure 29 A is described with reference to Figure 29 B to Figure 29 F.

Figure 29 B is different from Figure 29 A in the order of DFT precoder and extension blocks.In Figure 29 A, because the DFT symbol sebolic addressing equaling to export from DFT precoder in the function of SC-FDMA symbol rank extension blocks is multiplied by specific constant, even if so when the order of DFT precoder and extension blocks is changed, the value being mapped to the signal of SC-FDMA symbol is also identical.Therefore, signal processing for PUCCH format 3 can be performed with the order of chnnel coding, modulation, division, expansion and DFT precoding.Under these circumstances, division process and extension process can be performed by a functional block.Such as, modulation symbol can be expanded in SC-FDMA symbol rank, is divided into time slot alternatively simultaneously.As another example, when modulation symbol is divided into time slot, modulation symbol can be replicated with the size of applicable extended code, and the element of can be multiplied accordingly one to one modulation symbol and extended code.Therefore, the modulation symbol sequence generated at each time slot is extended at other multiple SC-FDMA symbol of SC-FDMA symbol level.Thereafter, corresponding with each SC-FDMA symbol complex symbol series is carried out DFT precoding by with SC-FDMA symbolic unit.

Figure 29 C is different from Figure 29 A in the order of modulator and divider.Therefore, can with at other combined channel of sub-frame level coding with divide and perform the signal processing for PUCCH format 3 in the order of each other modulation timeslot-level, DFT precoding and expansion.

Figure 29 D is different from Figure 29 C in the order of DFT precoder and extension blocks.As mentioned above, because the DFT symbol sebolic addressing equaling to export from DFT precoder in the function of SC-FDMA symbol rank extension blocks is multiplied by specific constant, even if so when the order of DFT precoder and extension blocks is changed, the value being mapped to the signal of SC-FDMA symbol is also identical.Therefore, by encoding at other combined channel of sub-frame level and dividing and in each other modulation timeslot-level, the signal processing for PUCCH format 3 can be performed.The modulation symbol sequence generated at each time slot is extended at other multiple SC-FDMA symbol of SC-FDMA symbol level, and the modulation symbol sequence corresponding with each SC-FDMA symbol is carried out DFT precoding by with SC-FDMA symbolic unit.Under these circumstances, modulation treatment and extension process can be performed by a functional block.Such as, when coded-bit is modulated, can directly expand the modulation symbol be generated in SC-FDMA symbol rank.As another example, when coded-bit is modulated, copy modulation symbol to be suitable for the size of extended code, and the element of can be multiplied accordingly one to one modulation symbol and extended code.

Figure 29 E illustrates that the PUCCH format 3 according to the present embodiment is applied to the situation (normal CP) of the structure of PUCCH format 2, and Figure 29 F illustrates the situation (expansion CP) being applied to the structure of PUCCH format 2 according to the PUCCH format 3 of the present embodiment.Baseband signal processing procedure be equal to reference to figure 29A to Figure 29 D describe those.Owing to reusing the structure of the PUCCH format 2 of existing LTE, so UCI SC-FDMA symbol in PUCCH format 3 and the quantity/position of RS SC-FDMA symbol and the different of Figure 29 A.

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

Herein, RS can reuse the structure of existing LTE.Such as, the cyclic shift of basic sequence is used can to define RS sequence (see equation 1).

Equation will be used to describe the signal processing of PUCCH format 3.For convenience's sake, assuming that the OCC of length 5 is used (such as, Figure 29 E to Figure 29 F).

First, use the specific scramble sequence of UE to carry out scrambler bits block b (0) ..., b (M _bit-1).Bit block b (0) ..., b (M _bit-1) can with the coded-bit b_0 of Figure 29 A, b_1 ..., b_N-1 is corresponding.Bit block b (0) ..., b (M _bit-1) at least one in ACK/NACK bit, CSI bit and SR bit can be comprised.The bit block of scrambling can be generated according to following equation

Herein, c (i) represents scramble sequence.C (i) comprises the pseudo random sequence by length-31gold sequence definition, and can be generated by following equation.Mod represents modular arithmetic.

The bit block of scrambling modulated, and complex modulation symbols block d (0) ..., d (M _symb-1) be generated.When performing QPSK modulation, complex modulation symbols block d (0) ..., d (M _symb-1) corresponding to Figure 29 A modulation symbol c_0, c_1 ..., c_N-1.

Use orthogonal sequence complex modulation symbols block d (0) is expanded in block formula mode (block-wise) ..., d (M _symb-1).Generated by following equation individual complex symbol collection.Frequency partition/the extension process of Figure 29 B is performed by following equation.Each complex symbol collection corresponds to a SC-FDMA symbol, and has (such as, 12) individual complex modulation value.

Hereinafter, traditional PUCCH Poewr control method will be described.PUCCH format 3 will be focused on.If Serving cell c is main plot, then provide the UE through-put power P for the PUCCH transmission at subframe i place as follows _pUCCH(i).

Equation 17

$P_{\mathrm{PUCCH}}\left(i\right)=\min \left\{\begin{array}{c}{P}_{\mathrm{CMAX},c}\left(i\right),\\ P_{0\_\mathrm{PUCCH}}+{\mathrm{PL}}_c+h(\&CenterDot;)+{\mathrm{\&Delta;}}_{F\_\mathrm{PUCH}}\left(F\right)+{\mathrm{\&Delta;}}_{\mathrm{TxD}}\left(F^{\&prime;}\right)+g\left(i\right)\end{array}\right\}$

P _{cMAX, c}i () is expressed as the maximum transmission power of the UE that Serving cell c configures.

P _{o_PUCCH}by P _{o_NOMINAL_PUCCH}and P _{o_UE_PUCCH}summation composition parameter.P is provided by higher level (such as, rrc layer) _{o_NOMINAL_PUCCH}and P _{o_UE_PUCCH}.

Parameter Δ is provided by higher level _{f_PUCCH}(F).Each Δ _{f_PUCCH}(F) value represents the value corresponding with PUCCH format relative to PUCCH format 1a.

When UE is configured to use two antenna ports to transmit PUCCH by higher level, provide parameter Δ by higher level _txD(F').Otherwise, that is, when UE is configured to use individual antenna port transmission PUCCH, Δ _txD(F') be 0.That is, antenna port transmission mode Δ is considered _txD(F') corresponding to power compensating value.

H () depends on PUCCH format.H () has n _cQI, n _hARQand n _sRin at least one function as parameter.

When PUCCH format 3, provide

Wherein, n _cQIrepresent the power compensating value be associated with channel quality information.More specifically, n _cQIcorrespond to the number for the information bit of channel quality information.N _sRrepresent the power compensating value be associated with SR.More specifically, n _sRcorresponding to the number of SR bit.If by the subframe (being called as SR subframe) that time during PUCCH format 3 transmitting HARQ-ACK is for SR transmits and configure, then UE transmits the SR bit (such as, 1 bit) and one or more HARQ-ACK bit that are jointly encoded by PUCCH format 3.Therefore, the size of control information SR subframe transmitted by PUCCH format 3 is all the time than HARQ-ACK payload size large 1.Therefore, if subframe i is SR subframe, then n _sR1, and if subframe i is non-SR subframe, then n _sR0.

N _hARQrepresent the power compensating value be associated with HARQ-ACK.More specifically, n _hARQbe associated with the number of (effective or actual) information bit.In addition, n _hARQbe defined as the number of the transmission block received on the downlink subframe.That is, carry out true constant dc power control by the number of the PDCCH for dividing into groups, this grouping is dispatched by eNB and is successfully decoded by UE.On the contrary, the number passing through configured DL community determines HARQ-ACK payload size.Therefore, if UE has Serving cell, then a n _hARQit is the number of the HARQ bit transmitted on subframe i.If UE has multiple Serving cell, n can be provided as follows _hARQ.In the tdd case, if UE from Serving cell c at subframe i-k _m(k _m∈ K, 0≤m≤M-1) in a upper SPS of reception discharge PDCCH(SPS release PDCCH), then n _{hARQ, c}=(at subframe i-k _mon the number of transmission block that receives)+1.If UE does not have from Serving cell c at subframe i-k _m(k _m∈ K:{k ₀, k ₁... k _m-1, 0≤m≤M-1) in a upper SPS of reception discharge PDCCH, then n _{hARQ, c}=(at subframe i-k _mon the number of transmission block that receives).When FDD, the situation being similar to TDD provides n _hARQ, and M=1 and k ₀=4.

embodiment: when configuring PUCCH simultaneously and PUSCH transmission pattern pUCCH power controls

Figure 30 illustrates the UL transmitting procedure according to existing 3GPP Rel-8/9.Figure 30 illustrates the SR process of buffer status reporting (BSR) and MAC layer.

With reference to Figure 30, if UL data become the transmission (S3002) that can be used in higher layer entities (such as, RLC entity or PDCP entity), then BSR process is triggered (S3004).BSR process is used for providing information relevant for the amount of available data transmitted in the UL buffer with UE to service eNB.If BSR process is triggered, then MAC layer determines whether there is the UL resource (such as, UL-SCH resource) (S3006) for newly transmitting distribution.If the UL-SCH resource be assigned with exists, then MAC layer generates MAC PDU(S3008).MAC PDU can comprise unsettled (pending) data and/or BSR MAC control element (CE) that can be used for transmitting.Thereafter, the MAC PDU of generation is transferred to physics (PHY) layer (S3010) by MAC layer.Via UL-SCH channel, MAC PDU is transferred to PHY layer.Consider PHY layer, MAC PDU is UL-SCH transmission block.Thereafter, the BSR process be triggered is cancelled (S3012).If there are unsettled data in a buffer after BSR MAC CE is transmitted, then eNB can consider BSR by UL-SCH Resourse Distribute to UE, and UE can use the resource be assigned with to transmit unsettled data.

On the contrary, if for newly to transmit and the UL resource of distributing does not exist, then SR process is triggered (S3014).SR process is for asking the UL-SCH resource for newly transmitting.If SR process is triggered, then MAC layer instruction PHY layer transmits SR(S3016 with signal).PHY layer transmits SR according to the instruction of MAC layer in SR subframe (subframe for SR transmits and configure).Thereafter, MAC layer determines whether the UL-SCH resource that can be used for new data transmission or BSR exists (S3018).If available UL-SCH resource does not exist, then SR process is unsettled, and step S3014 to S3016 is repeated.On the contrary, if available UL-SCH resource exists, if that is, pass through UL Permission assignment UL-SCH resource, then the SR process be triggered is cancelled (S3020).If become available by SR process UL-SCH resource, then according to BSR procedure performance step S3006 to S3012.

In a word, in existing 3GPP Rel-8/9, SR is triggered and does not transmit PUSCH(namely in SR subframe, and the UL-SCH resource/UL-SCH transmission block for SR subframe does not exist), UE transmits positive SR(positive SR by PUCCH format 1).On the contrary, if trigger SR and transmit PUSCH(namely in SR subframe, the UL-SCH resource/UL-SCH transmission block for SR subframe exists), then UE abandons SR transmission and by PUSCH transmission BSRMAC CE and/or unsettled data.

Meanwhile, in existing 3GPP Rel-8/9, can SR be triggered and (CQI only) PUSCH of aperiodic only CQI can be triggered in SR subframe.Only the PUSCH signal of CQI only comprises CQI and does not comprise data (that is, UL-SCH transmission block).Therefore, if only the PUSCH of CQI is triggered, because do not exist, so the SR be triggered is not cancelled for the available UL-SCH resource newly transmitted.That is, transmit while identical subframe requiring the PUSCH signal of only CQI and SR PUCCH signal.But, in existing 3GPP Rel-8/9, transmit while not allowing PUCCH and PUSCH.Therefore, in this example, the PUSCH of only CQI triggers and is considered as error configurations (mis-configuration) by UE.As a result, UE abandons aperiodic CQI PUSCH transmission, and only transmits positive SR by PUCCH format 1.In order to reference, if the value of CQI request field is 1, then MCS index IMCS is 29, and the number of the PRB be assigned with in the PDCCH signal of permitting for UL is less than or equal to 4(NPRB≤4), signalling analysis is that the PUSCH of only CQI distributes by UE.

As mentioned above, in existing 3GPP Rel-8/9, in order to have the UL transmission of low papr (PRPR) characteristic, transmit while forbidding PUCCH and PUSCH.But, in 3GPP Rel-10, PUCCH-and-PUSCH transmission pattern can be configured by RRC signaling simultaneously.That is, UE can transmit UCI(such as by PUCCH, HARQ-ACK and/or SR in identical subframe), and only transmit CSI(such as by PUSCH, CQI) or data (such as, UL-SCH transmission block).

According to the conventional power control method of the PUCCH format 3 described with reference to equation 17, if by PUCCH format 3 control information transmission in SR subframe, then control information comprises SR bit (such as, 1 bit) all the time, and the SR bit added is used to the through-put power (n increasing PUCCH _sR=1).In traditional Poewr control method, transmit while also supposing not configure PUCCH and PUSCH.That is, a subframe only can transmit PUCCH or PUSCH, and if PUCCH and PUSCH should be transmitted in identical subframe, then be transmitted the control information being scheduled as and being transmitted by PUCCH by PUSCH.Therefore, the transmission of the PUCCH in SR subframe indicates the UL-SCH resource/UL-SCH transmission block being used for SR subframe not exist.Under these circumstances, the SR bit being added to control information can be used to carry effective information all the time.

But, consider to carry out configuration UE with PUCCH-and-PUSCH transmission pattern, be necessary that more effectively performing power controls simultaneously.Such as, if configuration UE in supposition PUCCH-at the same time and-PUSCH transmission form, then the sight simultaneously transmitting PUCCH format 3 signal and PUSCH signal in SR subframe is possible.Under these circumstances, PUCCH format 3 signal can comprise SR bit and PUSCH signal can comprise UL-SCH transmission block.In addition, PUSCH signal only can comprise CSI.Described by with reference to Figure 30, if there is UL-SCH resource/UL-SCH transmission block for SR subframe, then the SR triggered is cancelled.That is, the existence of the UL-SCH transmission block in PUSCH signal can indicate negative SR(negative SR).Therefore, if PUSCH signal comprises UL-SCH transmission block, then the SR bit be included in PUSCH form 3 signal carries redundant information.Under these circumstances, because SR bit can have any value (uncertain), the value of SR bit can be regarded as invalid information.That is, if existed for SR subframe UL-SCH transmission block, then the SR bit be included in PUCCH format 3 signal corresponds to the dummy bit (dummy bit) without information.Therefore, be included in situation in PUCCH format 3 signal and dummy bit be not included in situation in PUCCH format 3 signal if process dummy bit comparably at PUCCH power control period, then may reduce power efficiency.

Hereinafter, the PUCCH-considered simultaneously and-PUSCH transmission pattern will be described and effectively perform the method that PUCCH power controls.Description below will focus on the method for UL Signal transmissions scenario correction h () according to equation 17.

If transmitted while being configured with PUCCH and PUSCH, then UL transmission sight is as follows:

(1) if transmission is simultaneously used for PUCCH format 3 signal and the PUSCH signal of HARQ-ACK in non-SR subframe, then PUSCH signal can comprise data (such as, UL-SCH transmission block) or only comprise CSI.

(2) if transmission is simultaneously used for PUCCH format 3 signal and the PUSCH signal of HARQ-ACK in SR subframe, then PUSCH signal can comprise data (such as, UL-SCH transmission block) or only comprise CSI.

When (1), SR bit is not included in the control information for PUCCH format 3.Therefore, the h () by using following equation can determine the power control of PUCCH.

Equation 18

$h(\&CenterDot;)=\frac{n_{\mathrm{HARQ}}+n_{\mathrm{SR}}-1}{2}=\frac{n_{\mathrm{HARQ}}+0-1}{2}$

When (2), will consider that SR is to consider following situation.

I) transmitting HARQ-ACK and SR can be carried out by PUCCH format 3, and only CSI can be transmitted by PUSCH.Under these circumstances, because SR bit is the effective value indicating actual SR information, so can consider that SR bit controls to the power performing PUCCH.Under these circumstances, the h () that can be controlled by the power using following equation to determine PUCCH.

Equation 19

$h(\&CenterDot;)=\frac{n_{\mathrm{HARQ}}+n_{\mathrm{SR}}-1}{2}=\frac{n_{\mathrm{HARQ}}+1-1}{2}$

Ii) can PUCCH format 3 transmitting HARQ-ACK and SR be passed through, and can PUSCH transmission UL-SCH transmission block (such as, BSR or data) be passed through.In this example, SR bit can be used to indicate actual SR information, no matter whether in SR subframe, transmits UL-SCH transmission block.In this example, if transmit UL-SCH transmission block in SR subframe, then the value (such as, 0) of the negative SR of SR bit instruction instruction all the time.Therefore, if there is UL-SCH transmission block in SR subframe, then the SR bit in PUCCH signal can be used to the mistake checking the control information transmitted by PUCCH.Because SR bit carries effective information, so the h () that can be controlled by the power using following equation to determine PUCCH.

Equation 20

$h(\&CenterDot;)=\frac{n_{\mathrm{HARQ}}+n_{\mathrm{SR}}-1}{2}=\frac{n_{\mathrm{HARQ}}+1-1}{2}$

Iii) can PUCCH format 3 transmitting HARQ-ACK and SR be passed through, and can PUSCH transmission UL-SCH transmission block (such as, BSR or data) be passed through.In this example, SR bit can be regarded as the dummy bit without information.That is, if there is not UL-SCH transmission block in SR subframe, then the SR bit (that is, actual SR information or significant bit) of the SR bit instruction reality in PUCCH is included in.Under these circumstances, SR indication information is sent to PHY layer with signal by the MAC layer of UE, and PHY layer arranges the value of SR bit according to SR indication information.The situation that SR subframe does not exist UL-SCH transmission block is also included within the situation of PUSCH SR subframe being transmitted only CSI (that is, not having CSI aperiodic of UL-SCH transmission block).On the contrary, if there is UL-SCH transmission block in SR subframe, be then included in SR bit instruction dummy bit (that is, virtual information or inactive bit) in PUCCH signal.Under these circumstances, SR indication information is not sent to PHY layer with information by MAC layer.But whether depend on and satisfy condition, SR bit can be set to dummy values by PHY layer.Dummy bit can have predetermined value.Such as, dummy bit can be set to the predetermined value of 0 or 1, and preferably can be set to 0.

More specifically, multiplexing HARQ-ACK bit stream [b can be conveyed through by PUCCH format 3 ₀b ₁b _m-1] and the control information that generates of SR bit s0, and can PUSCH transmission UL-SCH transmission block (that is, BSR or data) be passed through.HARQ-ACK bit stream and the multiplexing of SR bit comprise SR bit s ₀be attached to HARQ-ACK bit stream [b ₀b ₁b _m-1] end (or anterior) make to produce [b ₀b ₁b _m-1s ₀], and comprise and perform coding (that is, combined coding).In this example, SR bit is used as ambiguity in order to avoid control information size and the bit that inserts regularly.SR bit is set to predetermined value (such as, 0 or 1 and preferably 0), and eNB can ignore SR bit when decoding control information.But eNB can trigger the SR of UE according to the UL-SCH transmission block of PUSCH signal (such as, BSR or data) in the presence/absence of determining whether.

As mentioned above, in this example, because SR bit does not indicate actual SR information, so do not consider SR bit at power control period.In other words, if transmit PUCCH and PUSCH in SR subframe simultaneously, then can pass through PUCCH format 3 transmitting HARQ-ACK and empty SR, and can PUSCH transmission UL-SCH transmission block (such as, BSR or data) be passed through.The h () that the power that can determine PUCCH by following equation controls.

Equation 21

$h(\&CenterDot;)=\frac{n_{\mathrm{HARQ}}+n_{\mathrm{SR}}-1}{2}=\frac{n_{\mathrm{HARQ}}+0-1}{2}$

In this example, be different from equation 17, because pass through n _sR=0, not pass through n _sR=1 power performing PUCCH controls, even if so in SR subframe, the power efficiency for UL transmission also can increase.In this example, n _sRthe number of effective SR bit (there is the SR bit of actual information) can be indicated.In addition, if transmit HARQ-ACK by PUCCH format 3 in SR subframe, then by using the payload size of empty SR bit retentive control information equivalently always, the decoding efficiency of eNB can be increased.

Iv) can pass through PUCCH format 3 transmitting HARQ-ACK, and can PUSCH transmission UL-SCH transmission block (such as, BSR or data) be passed through.In this example, SR bit can be abandoned.Namely, if the payload size being included in the control information in PUCCH signal when there is not UL-SCH transmission block in SR subframe is N, then the payload size of the control information be included in PUCCH signal when there is UL-SCH transmission block in SR subframe becomes N-1.

Because SR bit is not transmitted, although so transmit PUCCH in SR subframe, be different from equation 17, pass through n _sR=0, not pass through n _sR=1 power performing PUCCH controls.Therefore, the h () that the power that can determine PUCCH by following equation controls.

Equation 22

$h(\&CenterDot;)=\frac{n_{\mathrm{HARQ}}+n_{\mathrm{SR}}-1}{2}=\frac{n_{\mathrm{HARQ}}+0-1}{2}$

Said method can be summarized as follows, the configuration of no matter simultaneously PUCCH-and-PUSCH transmission pattern.

Equation 23

$h(\&CenterDot;)=\frac{n_{\mathrm{HARQ}}+n_{\mathrm{SR}}-1}{2}$

If transmit PUCCH format 3 signal in non-SR subframe, then n _sR=0.

If transmit PUCCH format 3 signal in SR subframe,

If – UL-SCH transmission block does not exist, then n _sR=1, and

If – UL-SCH transmission block exists, then n _sR=1(equation 20) and n _sR=0(equation 21 to 22).

Figure 31 illustrates according to an embodiment of the invention via the process of PUCCH control information transmission.

With reference to Figure 31, eNB by PDCCH and PDSCH transmission corresponding thereto to UE(S3102).At least one in PDCCH and PDSCH can be received on a SCell.Thereafter, UE generates the control information be used for by the transmission of PUCCH format 3.Control information comprises the HARQ-ACK information for PDSCH.If transmit HARQ-ACK in SR subframe, then control information comprises SR bit further.SR bit is affixed to the end (or anterior) of HARQ-ACK bit stream, and SR bit and HARQ-ACK bit stream are jointly encoded.PUCCH format 3 signal is generated from control information by the process shown in Figure 29.UE arranges the PUCCH through-put power (S3104) being used for PUCCH transmission, and by power control process etc. by PUCCH format 3 Signal transmissions to eNB(S3106).

In this example, if transmit PUCCH format 3 signal in SR subframe, then consider that whether there is the UL-SCH transmission block be associated with SR subframe arranges the through-put power transmitted for PUCCH.Such as, consider whether there is the UL-SCH transmission block be associated with SR subframe, the transmission power setting method of equation 17 is used and h () can be replaced by equation 23.SR subframe is designated as the subframe of SR transmission and configuration.Configure SR subframe by higher level (such as, RRC), and can by period/skew specifies SR subframe.
