【発明の名称】通信端末装置および無線通信方法
Document Type and Number:
Japanese Patent JP3321419
Kind Code:
B2
Abstract:
Spreading sections 104 and 105 of the base station spread the respective distributed data using mutually orthogonal spreading codes and they are transmitted from antennas 106 and 107. Despreading sections 202 and 203 of the mobile station despread the received signals using the same spreading codes as those used at the base station, demodulation sections 204 and 205 demodulate the despread signals, received signal power measuring sections 207 and 208 measure their received signal powers from the demodulation result, received signal power combination section 209 combines the measured received signal powers and transmit power control section 212 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.
