ABSTRACT:
A mobile station apparatus communicates with a wireless base station apparatus to which closed-loop transmission diversity control is applied, the closed-loop transmission diversity control controlling phases of signals transmitted from two antennas based upon feedback information notified by the mobile station apparatus and transmitting the signals. The mobile station apparatus includes a control unit which determines whether to reflect an estimated phase result of the signals transmitted from the two antennas or not, depending on a channel type of signals transmitted from the wireless base station apparatus.
