ABSTRACT:
Despreading section203extracts a common control channel signal from each base station by performing despreading processing on a baseband signal from RF section202using a predetermined spreading code. Propagation loss measuring section206measures 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 comparator207detects a base station whose propagation loss is a minimum from among all base stations. Transmission data control section208controls 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 section211.
