Abstract
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.
