摘要： Spatial discrimination information is fed back at both the multi-antenna transmitter and the multi-antenna receiver connecting a UE and cells within a CoMP measurement set. With the UE feeding back the transmitter and the receiver side spatial discrimination information of each cell-to-UE connection, the composite spatial CSI over multiple sites/nodes can be determined. The approach is applicable for UEs with single or multiple receiving antennas, and the spatial discrimination information can be wideband long-term or subband short-term. In some embodiments, the spatial discrimination information at the receiver side is derived from the actual spatial channel while receiver implementation is taken into account. The spatial discrimination information at the transmitter and at the receiver can be fed back using codebooks for MIMO precoding.

The method comprises the steps of: an eNB bearing downlink grant information of a relay node onto an available Orthogonal Frequency Division Multiplex (OFDM) symbol of a first slot of a pre-allocated Physical Resource Block (PRB) pair used for bearing the R-PDCCH, wherein available OFDM symbols in the PRB pair, other than the OFDM symbol used for the downlink grant information, are used for bearing a Physical Downlink Shared Channel (PDSCH) of each relay node; the eNB transmitting the PRB pair bearing the downlink grant information and the PDSCH to the relay node. The present invention is well applicable to a link between an eNB and a relay node, and meanwhile enables backhaul resources to be used adequately.
