Abstract
A mobile station apparatus is provided which is capable of obtaining a diversity effect and preventing an increase in noise even if an antenna phase difference containing an error is detected. The mobile station apparatus includes a closed-loop transmit diversity control section for exerting, when the quality of the component from the second antenna is lower than a predetermined quality value based on the quality measured by the common pilot channel quality measurement section, control to cause the feedback information generation section not to use the detection result at the antenna phase difference detection section, and to continue to use the immediately preceding feedback information, control to cause the antenna verification section not to operate, and control to cause the first channel inference section to operate and the second channel inference section not to operate.
