ABSTRACT:
When a mobile station becomes a soft handover state, a reception quality monitor104measures reception quality of a pilot signal from each base station. Base station specifying means105generates a base-station select signal (BSse1) to specify base stations that have transmitted pilot channels of inferior reception quality. The base-station select signal is multiplexed with transmission data (r-txd), and the multiplexed signal is spread at a spreading circuit. The spread signal is transmitted to plural base stations through a transmitter111and a duplexer102.Then the base stations specified by this base-station specify signal stops transmission of downward signals.
