A CDMA mobile communication system is disclosed in which a reference value, an uplink signal SIR value, which is used in a closed-loop transmission power control is updated in base transceiver stations. The uplink signal target SIR value is updated independently at base transceiver stations and not at the base station controller. At the base transceiver station, when a decoder detects a loss of synchronization of a user signal from a mobile station, a demodulator adds a step value ΔSIR that has been set in advance to the uplink signal SIR value that has been reported from the base station controller to obtain an uplink signal target SIR provisional value. When this uplink signal target SIR provisional value is smaller than an uplink signal target SIR maximum value that has been set in advance, the uplink signal target SIR value is updated to the uplink signal target SIR provisional value.
