Abstract
Before a mobile station is in dormancy, power control channels of forward and reverse links are established between the mobile station and a base station independently of traffic channels of forward and reverse links. When the mobile station is in dormancy, 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 dormant mobile station is achieved.
