MU-CQI METHOD AND APPARATUS FOR ESTIMATING MULTIPLE STREAM MULTI USER CQI BASED ON PER STREAM CHANNEL GAIN FEEDBACK IN WIRELESS COMMUNICATION SYSTEM

摘要

The present invention relates to a method and an apparatus for estimating a multi-stream MU-CQI using channel gain feedback for each stream in a wireless communication system, and a method of transmitting feedback information of a terminal in a wireless communication system of the present invention includes: Estimating a downlink channel, determining a number of streams based on the estimated downlink channel, generating feedback information corresponding to the determined number of streams, and transmitting the generated feedback information to a base station And transmitting the data.
