Abstract
Methods for a User Equipment (UE) to transmit Channel Quality Index (CQI) feedback information, and an indicator in feedback information, to an evolved Node B (eNB) in a wireless communication system, and apparatuses therefore, are provided. A method for a UE to transmit CQI feedback information to eNB in a wireless communication system, includes obtaining one or more Transmission Points Configurations for Coordinated MultiPoint (CoMP) (TPCCs), each TPCC including a unique combination of one or more cells in a 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 one or more 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.
