Abstract
A base transceiver station (200) that transmits same data through a common channel shared by a transmission path includes a cell total transmit power detector (41) that detects, with respect to each of a plurality of cells, a total amount of the transmit power for transmitting the data to mobile stations (300) located inside each of the cells, a relative value information receiver (42) that receives relative value information for relatively correcting the total transmit power, from the base transceiver station controller, and a weight adjustment and power determination unit (43) that corrects the total transmit power for transmitting the data with respect to each cell, based on the relative value information received by the relative value information receiver and the total transmit power detected by the cell total transmit power detector, and determines a modified total transmit power.
