MULTI-INPUT MULTI-OUTPUT COMMUNICATION METHOD AND MULTI-INPUT MULTI-OUTPUT COMMUNICATION SYSTEM OF ENABLING THE METHOD

摘要

MIMO communication system is disclosed. Multiple-input multiple-output communication system user (user) terminal to the selected beamforming (beam-forming) vector the first channel quality information (Channel Quality Information, CQI) feedback from the user terminal of claim 1 CQI receiving section receives the data stream and associated with the (data includes a first 2 CQI generated in consideration of the transmission rank (transmission rank) related to the number of generating the second channel quality information to correct the channel quality information of the first stream).
