摘要： 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 measuring 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.

摘要： A propagation loss measuring section 207 appropriately changes a measuring method according to the reception type of system informed from a base station so as to measure propagation losses. A propagation loss comparator 209 compares the propagation loss between the respective cells. A transmission slot controller 210 controls a data assembling section 211 and spreader 213 in such a way to transmit a signal to a base station existing in a cell with a smaller propagation loss. A transmission power controller 208 controls a RF section 202 in such a way to transmit a signal with a transmission power value obtained by adding the propagation loss value at each cell to a target reception power value at each base station.

摘要： Despreading section 203 extracts a common control channel signal from each base station by performing despreading processing on a baseband signal from RF section 202 using a predetermined spreading code. Propagation loss measuring section 206 measures a propagation loss for each base station using the reception level of the common control channel signal and the transmission level of this common control channel signal. Propagation loss comparator 207 detects a base station whose propagation loss is a minimum from among all base stations. Transmission data control section 208 controls the timing of transmission data in the data composition section so that an dedicated traffic channel signal is transmitted to the detected base station and controls the spreading code in spreading section 211.
