摘要
Disclosed is a feedback control method in closed-loop transmit diversity in which feedback information representing amounts of amplitude and phase control is transmitted from a mobile station to a radio base station. The mobile station receives downlink pilot signals, which are transmitted by a handover-destination base station, during handover control, calculates feedback information, which represents amounts of amplitude and phase and phase control transmitted to the handover-destination base station, beforehand based upon the pilot signals received, and transmits the feedback information to the handover-destination base station before completion of base-station changeover by handover.
