FEEDBACK METHOD AND APPARATUS FOR COOPERATIVE MULTI-POINT COMMUNICATION IN COMMUNICATION SYSTEM

摘要

A feedback method and apparatus are provided for Cooperative Multi-Point (CoMP) communication in a communication system. The method includes checking a number of feedback allocations configured by RRC signaling, determining a number of bits of an aperiodic feedback indicator based on the checked number of feedback allocations, receiving DCI including the aperiodic feedback indicator, interpreting the aperiodic feedback indicator, based on the determined number of bits of the aperiodic feedback indicator, and performing aperiodic feedback of at least one feedback allocation, based on the aperiodic feedback indicator.
