Abstract

In intra-cell CoMP transmission, if Remote Radio Heads (RRHs) have different cell IDs, a CoMP UE has to transmit a plurality of PMIs for the respective RRHs (i.e., antenna ports) as CSI feedback information. However, the present invention proposes a method of transmitting information about antenna ports to be involved in CoMP transmission as CSI feedback information by using one PMI and a specific CSI-RS antenna port table because RRHs within a cell have the same cell ID. Accordingly, overhead of feedback information can be greatly reduced because an index using the one PMI and the specific CSI-RS antenna port table is transmitted as the CSI feedback information.
