Growth of interference wave power resulting from the growth of transmission power of the DPCH is prevented to increase line capacity while increasing reliability of control information. When a base station compares the reception SIR of the DPCH 1 from a mobile station with the desired SIR of the base station, and the reception SIR is smaller than the desired SIR as a result of the comparison, the base station instructs the mobile station to increase transmission power when the DPCH 1 is sent from the base station to the mobile station, but the base station increments the desired SIR by a predetermined offset value (Delta) when the HS-PDSCH is sent from the base station to the mobile station. Consequently, the mobile station increases transmission power compared to the case where only the DPCH 1 is received. Also, the HS-PDSCH is sent to each mobile station in different timing, and therefore only the mobile station increases transmission power.
