ABSTRACT:
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 DPCH1from 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 DPCH1is sent from the base station to the mobile station, but the base station increments the desired SIR by a predetermined offset value (Δ) 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 DPCH1is received. Also, the HS-PDSCH is sent to each mobile station in different timing, and therefore only the mobile station increases transmission power.
