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

Perhaps, in the present embodiment, RN determines orthogonal sequence according to the orthogonal sequence table shown in table 5, can give the reserved special RB of R-PUCCH of RN, allows the PUCCH information of UE in the R-PUCCH information of RN and tie link send on different Resource Block.Give the method for the reserved special Resource Block of the R-PUCCH of RN can be for eNB to the reserved special RB of the R-PUCCH of RN, as shown in Figure 5, for a kind of resource block assignments figure in the embodiment of the present invention, in the Resource Block shown in Fig. 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 next-door neighbour PUCCH form 2/2a/2b and the multiplexing resource of R-PUCCH form 2/2a/2b and afterwards, on frequency domain, to RN, for transmitting R-PUCCH form 1/1a/1b, code channel adds up to N to reserved m RB resource _r-PUCCH.M 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 code 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 code Taoist monastic name n of PUCCH form 2/2a/2b _pUCCH ⁽²⁾only for calculating 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 code 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 code Taoist monastic name n of R-PUCCH form 2/2a/2b _r-PUCCH ⁽²⁾only for calculating the cyclic shift of its ZC sequence.

In the special-purpose RB resource of reserved RN, reserve the semi-static response message (Acknowledgement of fixing resource to RN, ACK) and dispatch request indication (Scheduling Request Indicator, SRI), subchannel adds up to N1_PUCCH_AN_RN, this subchannel sum can be configured by high level, and 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 transmitted for the RN dynamic ack adds up to N _r-PUCCH-N1_PUCCH_AN_RN, 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 configures RN.

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

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

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

middle selection orthogonal sequence.Because all needing reserved last symbol, discrete relaying sub-frame of uplink and last the relaying sub-frame of uplink configured continuously do 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 configured continuously, UE is only at cell-level detection reference signal (Sounding ReferenceSignal, SRS) subframe just can be used the orthogonal sequence that length is 3, therefore, need to be configured to cell-level SRS subframe to last relaying sub-frame of uplink of discrete relaying sub-frame of uplink and configuration continuously, be to need to comprise all discrete uplink relay subframe and last uplink relay subframe of configuration continuously in the cell-level SRS subframe of eNB configuration.

In embodiments of the present invention; due to the transmitting-receiving translation and protection interval of last symbol in first symbol in first time slot in uplink relay subframe and/or second time slot as RN; 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 (Normal Circuit Prefix) transmitting scene, one of them Bearer Channel quality indication (Channel Quality Indicator of 2 frequency pilot signs in each time slot for R-PUCCH form 2/2a/2b, 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 present invention R-PUCCH form 2/2a/2b under the general cyclic prefix scene and send schematic diagram, when only having CQI, the CQI symbol had more is put on second frequency pilot sign of each time slot and transmits, 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, by ACK and CQI combined coding, be 20bit, be modulated into 10 symbols through Quadrature Phase Shift Keying (QuadraturePhase Shift Keying, QPSK), one of them symbols carry is transmitted on last pilot tone of each time slot.In Fig. 6, d (i) means a symbol after CQI or CQI and the modulation of ACK/NACK combined coding, and P means the frequency pilot sign of demodulation pilot frequency (Demodulation Reference Signal, DMRS).

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