Perhaps to symbol 1, symbol 2 and the symbol 6 of second time slot in the relay sub-frame shown in Fig. 2 be multiplied by 1 respectively,

With

In the present embodiment, RN determines orthogonal sequence according to the orthogonal sequence table shown in the table 5, therefore, for fear of the interference between RN and the UE, in tie link, the Resource Block of multiplexing PUCCH form (format) 1/1a/1b of UE and RN (Resource Block, RB) on, at first time slot or second time slot of this uplink relay subframe, the orthogonal sequence that UE uses is [1 11 1].

Perhaps, in the present embodiment, RN determines orthogonal sequence according to the orthogonal sequence table shown in the table 5, reserves special RB can for the R-PUCCH of RN, allows promptly the PUCCH information of UE sends on different Resource Block in R-PUCCH information and the tie link of RN.Method to the special Resource Block of the R-PUCCH reservation of RN can be that eNB reserves special RB for the R-PUCCH of RN, as shown in Figure 5, be a kind of resource block assignments figure in the embodiment of the invention, in Resource Block shown in Figure 5, the multiplexing resource of PUCCH form 2/2a/2b and R-PUCCH form 2/2a/2b is positioned at the edge of this Resource Block, in this Resource Block before the multiplexing resource of next-door neighbour PUCCH form 2/2a/2b and R-PUCCH form 2/2a/2b and afterwards, reserve m RB resource on the frequency domain and be used to transmit R-PUCCH form 1/1a/1b to RN, code channel adds up to N _R-PUCCHM can choose suitable value according to the deployment number of RN, for example can get 1.In embodiments of the present invention, PUCCH can be divided into PUCCH form 1/1a/1b and PUCCH form 2/2a/2b, wherein, and the sign indicating number Taoist monastic name n of PUCCH form 1/1a/1b _PUCCH ⁽¹⁾Can be used for calculating the cyclic shift of ZC sequence of PUCCH form 1/1a/1b and the sequence index of orthogonal sequence; PUCCH form 2/2a/2b does not have the orthogonal sequence expansion, the sign indicating number Taoist monastic name n of PUCCH form 2/2a/2b _PUCCH ⁽²⁾Only be used to calculate the cyclic shift of its ZC sequence.Similar with the classification of PUCCH, R-PUCCH also can be divided into R-PUCCH form 1/1a/1b and R-PUCCH form 2/2a/2b, wherein the sign indicating number Taoist monastic name n of R-PUCCH form 1/1a/1b _R-PUCCH ⁽¹⁾Can be used for calculating the cyclic shift of ZC sequence of R-PUCCH form 1/1a/1b and the sequence index of orthogonal sequence; R-PUCCH form 2/2a/2b does not have the orthogonal sequence expansion, the sign indicating number Taoist monastic name n of R-PUCCH form 2/2a/2b _R-PUCCH ⁽²⁾Only be used to calculate the cyclic shift of its ZC sequence.

In the special-purpose RB resource of the RN that reserves, reserve fixing resource and give the semi-static response message (Acknowledgement of RN, ACK) and dispatch request indication (Scheduling Request Indicator, SRI), subchannel adds up to N1_PUCCH_AN_RN, this subchannel sum can be disposed by high level, and then the resource number of the semi-static SRI of RN and ACK is 0～N1_PUCCH_AN_RN-1.

In the special-purpose RB resource of RN, the subchannel that is used for the transmission of RN dynamic ack adds up to N _R-PUCCH-N1_PUCCH_AN_RN is according to the original position of the shared resource of down control channel of RN and the dynamic ack resource that N1_PUCCH_AN_RN disposes RN.

UE uses code channel resource transmission SRI, semi-static ACK and the dynamic ack among the PUCCH lattice 1/1a/1b.

Between PUCCH form 1/1a/1b Physical Uplink Shared Channel (Physical Uplink SharedChannel, PUSCH) and relaying Physical Uplink Shared Channel (Relay Physical Uplink SharedChannel, R-PUSCH) multiplexing Resource Block, PUSCH is the data channel of tie link between UE and the eNB, and R-PUSCH is the data channel of repeated link between RN and the eNB.

When the transmitting-receiving conversion is done in last symbol reservation of uplink relay subframe, interference for fear of repeated link and tie link different length orthogonal sequence, it is 3 orthogonal sequence that tie link UE also will adopt extension length at second time slot of uplink relay subframe, this orthogonal sequence can be identical with the orthogonal sequence that RN uses, as from

The middle orthogonal sequence of selecting.Because all needing to reserve last symbol, last relaying sub-frame of uplink of discrete relaying sub-frame of uplink and configuration continuously does the transmitting-receiving conversion, need discrete relaying sub-frame of uplink identical by the orthogonal matrix of RN and UE with second time slot of last the relaying sub-frame of uplink that disposes continuously, UE is only at cell-level detection reference signal (Sounding ReferenceSignal, SRS) just can to use length be 3 orthogonal sequence to subframe, therefore, need be configured to cell-level SRS subframe to last relaying sub-frame of uplink of discrete relaying sub-frame of uplink and continuous configuration, be i.e. need last uplink relay subframe that comprises all discrete uplink relay subframe and dispose continuously in the cell-level SRS subframe of eNB configuration.

In embodiments of the present invention; because last symbol in first symbol in first time slot in the uplink relay subframe and/or second time slot as the transmitting-receiving translation and protection of RN at interval; few one of the data symbol number that R-PUCCH form 2/2a/2b can use; therefore, can realize transmission by the resource mapping of R-PUCCH form 2/2a/2b or the mode of combined coding.Under general cyclic prefix (the Normal Circuit Prefix) transmitting scene, R-PUCCH form 2/2a/2b indicates (Channel Quality Indicator with one of them Bearer Channel quality of 2 frequency pilot signs in each time slot, or a symbol after the modulation of ACK and CQI combined coding CQI).As mistake! Do not find Reference source.Be depicted as in the embodiment of the invention that R-PUCCH form 2/2a/2b sends schematic diagram under the general cyclic prefix scene, when having only CQI, a CQI symbol that has more is put on second frequency pilot sign of each time slot and transmits, promptly 9 in 10 CQI symbols are in the CQI transmitted over resources, and remaining 1 CQI symbol transmits on pilot tone; When transmitting CQI and ACK simultaneously, with ACK and CQI combined coding is 20bit, (QuadraturePhase Shift Keying QPSK) is modulated into 10 symbols, and one of them symbols carry is transmitted on last pilot tone of each time slot through Quadrature Phase Shift Keying.In Fig. 6, a symbol after d (i) expression CQI or CQI and the modulation of ACK/NACK combined coding, P represents demodulation pilot frequency (Demodulation Reference Signal, frequency pilot sign DMRS).

First of repeated link sub-frame of uplink or last symbol are reserved the transmitting-receiving translation and protection interval as RN, can solve the problem of a few available data symbol among the R-PUCCH form 2/2a/2b by reducing the bit number after CQI encodes.Be about to coding from (20, A) the Reed Muller (Reed Muller, RM) coding change to (18, A) RM coding.Although the SC-FDMA symbolic number is few 1, CQI or CQI and ACK unite process (18, A) RM coding, QPSK modulate and can just be mapped on 9 symbols.

This yard battle array can be from LTE agreement as shown in table 6 PUCCH CQI coding (20, A) traversal search in the sign indicating number battle array.
