BASE STATION DEVICE, MOBILE STATION DEVICE AND TRANSMISSION POWER CONTROLLING METHOD

摘要

A diffusion code reporting unit (201) reports diffusion codes corresponding to communicating mobile station devices to respective mobile station devices, a separation unit (212) separates, from a received signal, information indicating an interference station detected from reverse-diffusion results in respective mobile station devices, and a control unit (213) reduces the transmission power of a signal to the interference station.
