发明名称 MOBILE COMMUNICATION SYSTEM AND COMMUNICATION CONTROL METHOD
摘要 A mobile communication system performs a downlink multi-antenna transmission by applying both a precoder matrix that defines downlink transmission directivity and a rank that defines a number of downlink signal sequences. The mobile communication system has a user terminal that feeds back, to a base station, feedback information about a target frequency band. The feedback information includes a plurality of combinations of precoder matrix information indicating the precoder matrix and rank information indicating the rank.
