Abstract
In a cellular system, each mobile station concurrently linked to plural link base stations in soft handover state and receiving packet from the packet-transmitting base station controls a transmission power of an up-link dedicated physical channel based on a first transmission power control information included in down-link dedicated physical channels of the link base stations. In other state, the mobile station controls the transmission power based on a second transmission power control information included in a down-link dedicated physical channel of the packet-transmitting base station. This accelerates the power increase up to a target power level causing that the measured signal-to-interference-ratio at the packet-transmitting base station reaches a target signal-to-interference-ratio, thereby improving receiving quality of control signal from the mobile station at the packet-transmitting base station.
