Abstract:
1. A method for a User Equipment (UE) to transmit Channel Quality Index (CQI) feedback information to an evolved Node B (eNB) in a wireless communication system, the method comprising: obtaining a plurality of Transmission Points Configurations for Coordinated MultiPoint (CoMP) (TPCCs), each TPCC including a unique combination of one or more cells in a CoMP measurement set, wherein the plurality of TPCCs comprises each possible combination including an anchor cell of the cells in the CoMP measurement set; estimating a channel for one or more cells in the CoMP measurement set; computing a CQI for each of at least one of the TPCCs, each CQI being computed using one or more estimated channels that correspond to the combination of one or more cells included in a corresponding TPCC; generating CQI feedback information based on the one or more CQIs; and transmitting the CQI feedback information.
