Abstract
A base transceiver station (200) that transmits same data to a plurality of mobile stations (300) using a common channel includes a maximum transmit power detector (41) that detects a maximum transmit power value at each spreading factor during transmission of the data from a transmit power of the data transmitted to the plurality of mobile stations (300) in cells controlled by the base transceiver station (200), and a transmit power determination unit (42) that determines a transmit power at each spreading factor based on the relation between the maximum transmit power values detected and the spreading factors.
