METHOD AND APPARATUS FOR TRANSMITTING AND RECEIVING FEEDBACK FOR COOPERATIVE COMMUNICATION SYSTEM

摘要

PURPOSE: A feedback transceiving method for a CoMP(Cooperative Multi-Point) system and a device thereof are provided to efficiently manage a CoMP by building a CoMP mode based on an LTE-A(Long Term Evolution-Advanced) system. CONSTITUTION: A communication unit(710) receives feedback set information. The communication unit receives identification information for identifying a CoMP set. A control unit(720) extracts the CoMP set by using the identification information and a feedback set. The control unit detects a first feedback timing and a first feedback mode for a first CSI-RS(Channel Status Information Reference Signal) not included in the CoMP set among CSI-RSs included in the feedback set. The control unit generates a feedback for the first CSI-RS according to the first feedback timing and the first feedback mode.
