摘要： A network sends to a user equipment UE a reference signal configuration, and from receiving it the UE selects a codeword identifying a cooperative multipoint CoMP transmission scheme. There is a CoMP scheme selection codebook from which the UE selects the codeword corresponding to its recommended CoMP scheme. The UE sends to the network that codeword which identifies the CoMP transmission scheme, along with the CSI feedback characterizing the CoMP transmission scheme. From that codeword which the network receives it determines the UE's assumed CoMP transmission scheme, which the network uses to determine how the CSI feedback, received from the UE, was calculated by the UE (for example, joint transmission, or dynamic point selection with or without muting, or coordinating scheduling/beamforming). The network uses this information for selecting a CoMP transmission scheme for downlink CoMP transmissions to the UE.
