A radio base station (200) transmits TPC bits (+1) or TPC bits (−1) to a mobile station at predetermined time intervals in order to approximate the reception quality of a radio signal to a target reception SIR, said TPC bit (+1) increasing the transmission power of the radio signal just by a given step, and said TPC bit (−1) decreasing the transmission power of the radio signal just by a given step. The radio base station (200) is provided with: a TPC bit monitoring unit (211) which monitors whether the ratio of TPC bits (+1) transmitted in the predetermined period exceeds n %; and a TPC bit adjustment unit (213) which transmits the TPC bits (−1) consecutively Y times at the time intervals, when it is detected that the ratio has exceeded n %.
