Abstract
Spreading sections and of the base station spread the respective distributed data using mutually orthogonal spreading codes and they are transmitted from antennas and . Despreading sections and of the mobile station despread the received signals using the same spreading codes as those used at the base station, demodulation sections and demodulate the despread signals, received signal power measuring sections and measure their received signal powers from the demodulation result, received signal power measuring section combines the measured received signal powers and transmit power control section controls transmission power based on the combined received signal power. When carrying out diversity reception through a plurality of antennas at the base station, this suppresses transmit power control errors to a small level at the mobile station.
