<p>PROBLEM TO BE SOLVED: To optimize an optimum value of a power ratio between the PDSCH and the DPCH according to a position of a mobile station, and to maintain the receiving quality of the PDSCH at a fixed level regardless of the position of the mobile station on the soft handover when a PDSCH(Physical Downlink Shared Channel) is transmitted by only one specific base station and a DPCH(Dedicated Physical Channel) is simultaneously transmitted by a plurality of base stations while controlling a transmitting power of the PDSCH according to the DPCH. SOLUTION: In a specific base station 1, a value of a ratio between the transmitting power of the PDSCH and that of the DPCH that is a dedicated channel is controlled to be optimized according to the position of the mobile station on the soft handover so that it becomes the ratio determined based on a measured value of a received power of a shared channel or the dedicated channel in the mobile stations of a soft handover base station 1, 2. To be more specific, the mobile station 10 notifies the specific base station 1 of these measuring results, and the specific base station 1 notified thereof multiplies by a coefficient determined based thereon the transmitting power of the DPCH that is the dedicated channel transmitted by the base station itself and transmits it.</p> |
