Transmission power control scheme for mobile communication system

摘要

A transmission power control scheme for a mobile communication system for suppressing the transmission power to an absolutely necessary minimum level, and increasing the subscriber capacity by reducing an amount of interference. In this scheme, at a time of controlling a transmission power of each radio channel at one of the base station (3a) and the mobile station (1a,1b) so as to make a difference between a target CIR and a reception CIR of each radio channel at another one of the base station (3b) and the mobile station smaller (1a,1b), the target CIR for all radio channels at that another one of the base station and the mobile station are set independently, and/or the target CIR for each radio channel is changed at that another one of the base station and the mobile station, according to a channel quality of each radio channel at either one of the base station and the mobile station. <IMAGE>
