Abstract
A transmission power control system of a mobile communications base stations controls the transmission power level of a mobile station. A mobile station receives a transmission power control command transmitted over a forward-link from a base station for making a reception condition of a reverse-link at the base station substantially fixed. A reception quality estimation section of the mobile station estimates the reception quality of the transmission power control command, and a transmission power control section controls the transmission power with a control width which is varied in response to the reception quality estimated by the reception quality estimation section. If the communication conditions of the forward-link becomes unfavorable, the transmission power of the mobile station is prevented from being displaced by a significant amount in a direction different from the last instruction from the base station.
