Abstract
Cellular mobile communication system includes a plurality of base stations connected to a relay station, each base station having adaptability for coping with change in traffic volume within a relevant cell covered thereby. Each base station includes a variable gain power amplifier for amplifying a pilot signal and a power control circuit for controlling the gain of the power amplifier. The power control circuit controls gain of a pilot signal sending power in accordance with a control signal supplied from a device installed in a relay station for monitoring traffic states of the individual base stations. The relay station issues a command for lowering the power gain for the base station which covers a traffic-concentrated cell while raising the power gain for the base stations covering the neighboring cells, to thereby contract the size of the traffic-concentrated cell. With a smaller number of base stations, communication demand can be controlled over a broad area.
