Abstract
A PSCG feedback-based multi-stream multiuser CQI estimation method and apparatus is provided for estimating multi-stream MU-CQI efficiently based on per-stream channel gain feedback. A feedback information transmission method of a terminal in a wireless communication system according to the present disclosure includes estimating a downlink channel based on a channel state information reference signal transmitted by a base station, determining a number of streams based on the estimated downlink channel, generating the feedback information corresponding to the number of streams, and transmitting the feedback information to the base station.
