Abstract
In the case where a PDSCH is transmitted by only one specific base station and a DPCH is simultaneously transmitted by a plurality of base stations while controlling a transmitting power of the PDSCH according to the DPCH, an optimum value of a power ratio between the PDSCH and the DPCH according to a position of a mobile station is optimized, and the receiving quality of the PDSCH at a fixed level regardless of the position of the mobile station on the soft handover is maintained to be constant. In a specific base station, 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 of a soft handover base station in the mobile station. To be more specific, the mobile station notifies the specific base station of these measuring results, and the specific base station notified thereof multiplies by a coefficient determined based thereon the transmitting power of the DPCH that is the dedicated channel trans…
