Before a mobile station 2 becomes dormant, power control channels of forward and reverse links are established between the mobile station and a base station 1 independently of traffic channels of forward and reverse links. When the mobile station becomes dormant, a dormant power control signal is transmitted from the base station to the mobile station through the power control channel of the forward link. Then a dormant power control process is carried out at the mobile station, in accordance with the dormant power control signal transmitted from the base station, to produce a reference data signal subject to the dormant power control process. In response to the power-controlled data signal, the base station produces the dormant power control signal in accordance with a reception level of the reference data signal. Thus, closed loop power control for a dormant mobile station is achieved. Furthermore, the traffic channels of the forward and reverse links may be broken off prior to the step of transmitting the dormant power control signal. Additionally the mobile station may share the power control channels with other mobile stations in the same service area. |
