CONFIGURATION OF COORDINATED MULTIPOINT TRANSMISSION HYPOTHESES FOR CHANNEL STATE INFORMATION REPORTING

摘要

A system and method for providing an eNodeB (18) with the flexibility to configure a Channel State Information (CSI) report to match a specific Coordinated Multipoint (CoMP) transmission hypothesis, which is a candidate for a downlink transmission to a User Equipment (UE) (20) is disclosed. A UE (20) receives, from the eNodeB (18), a configuration message that specifies a CSI report. The CSI report is specified by a particular interference hypothesis and a particular desired signal hypothesis corresponding to data transmission over at least one effective channel characterized by a specific reference signal. The UE (20) estimates interference according to the interference hypothesis, and/or estimates at least one effective channel by performing measurements on the specific reference signal, and determines a CSI report based on the interference estimation and on the estimated effective channel. The UE (20) also transmits the CSI report to the eNodeB (18).
