Abstract
A scheme for controlling transmission powers during a soft handover in a CDMA mobile communication system, in which the receiving quality can always satisfy the reference quality even when a relationship between the receiving qualities at the base stations is reversed within the selective combination interval. In this transmission power control scheme, one radio channel among a plurality of radio channels is selected as a reference radio channel at the prescribed selective combination interval, and then a transmission power control is carried out at a prescribed transmission power control interval so that a receiving quality of the reference radio channel satisfies a prescribed reference quality, while not switching the reference radio channel within the prescribed selective combination interval.
