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.

[ What is claimed is:] [1.] A method for controlling transmission powers during a soft handover in a CDMA mobile communication system where a mobile station is simultaneously connected with a plurality of base stations via a plurality of radio channels while said plurality of base stations are connected with a combining station via a plurality of wire transmission lines so that a plurality of transmission signals from said plurality of base stations to the combining station are selectively combined at a prescribed selective combination interval by the combining station and a plurality of transmission signals from said plurality of base stations to the mobile station are selectively combined at the prescribed selective combination interval by the mobile station, the method comprising the steps of:selecting one radio channel among said plurality of radio channels as a reference radio channel at the prescribed selective combination interval; andcarrying out a transmission power control 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.
