Patent ID: 8694038

Claim:
A mobile station for communicating with a wireless base station that controls the phase of signals to be transmitted from two antennas based on feedback information from the mobile station, the mobile station comprising: an estimating unit which estimates the phase of the signals from the two antennas; a reception signal processor which carries out a reception signal process to a reception signal from the wireless base station based on a result of the estimation by the estimating unit; and a controller which controls a timing of reflecting the estimation result by the estimating unit on the reception signal processor in response to a stage in a process of communication regarding an uplink to the wireless base station, wherein in controlling a timing of reflecting the estimation result, the controller causes the estimation result to reflect on the reception signal process before the establishment of the synchronism of the uplink but not to cause the estimation result to reflect on the reception signal process after the synchronism is established.
