    • 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.

    • A method and system for feedback of spatial CSI of a spatial channel that connects receive antennas at user equipment and multiple transmit antennas. Spatial discrimination information is provided as feedback at the transmitter and the receiver connecting the user equipment and a cell. With the user equipment providing the transmitter and the receiver side spatial discrimination information of each sub-channel as feedback, the composite spatial CSI over multiple segments of transmit antennas can be determined. The user equipment may have one or multiple receiving antennas, and the spatial discrimination information can be 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 can be provided as feedback using codebooks for MIMO precoding.
