Radio communications system and control method therefor

摘要

A radio base station which receives a first and a second communication channel from a radio communications device comprises a control circuit for detecting the reception quality of the first communication channel, conducting an inner-loop power control for controlling transmission power of the first communication channel from the radio communications device based on the reception quality and an inner-loop power control target value, and adding a power control offset to the inner-loop power control target value before starting a communication through the second communication channel.
