(57) Information regarding reception quality of DSCH in a mobile station 10 is acquired by a DSCH quality acquisition unit 33, and transmission power of the DSCH in a DSCH transmission unit 21 of a base transceiver station 20 is further controlled based on the information regarding the reception quality of the DSCH in addition to transmission power of Downlink A-DPCH by a offset calculation unit 35. Therefore, it is made possible to optimize this transmission power of the DSCH while restricting deterioration in the reception quality. Note that the present invention can also be applied to control of transmission power of HS-SCCH in HSPDA.
