A base station (1) receives a HS-DPCCH at a base station reception unit (22) through a base station receiving antenna (12), and the HS-DPCCH is despread and demodulated by the base station despreading unit (21). The demodulated HS-DPCCH is decoded by the base station channel decoding unit (20), and ACK/NACK/DTX is extracted at a HARQ-ACK detection unit (19) and then the HS-DPCCH is delivered to a HS-SCCH transmission power decision unit (18). The HS-SCCH transmission power decision unit (18) decides transmission power of a HS-SCCH according to the detection status of the ACK/NACK/DTX. The HS-SCCH transmission power thus decided is notified to a base station control unit (17), which notifies the same to a base station spreading/modulation unit (14), so that the decided value is applied to the HS-SCCH transmission power.
