METHOD AND APPARATUS FOR FEEDING PARTIAL CQI BACK BY TERMINAL IN WIRELESS COMMUNICATION SYSTEM

摘要

A method of reporting channel state information (CSI) to a base station by a terminal in a wireless communication system is disclosed. Specifically, the method includes configuring feedback chains corresponding to a plurality of CSI-reference signals (RSs) through upper layer signaling, receiving the plurality of CSI-RSs from the base station, calculating a complete channel quality indicator (CQI) for a whole channel using the plurality of CSI-RSs and dividing the complete CQI into partial CQIs corresponding to the respective feedback chains, and reporting CSI items including the partial CQIs to the base station through the feedback chains.
