BASE STATION DEVICE, USER DEVICE AND METHOD USED IN MOBILE COMMUNICATION SYSTEM

摘要

A base station device includes: judging means which judges whether a propagation loss reported from a user device satisfies a predetermined condition; means which creates an instruction signal indicating whether the user should lower the transmission power in response to a request for lowering power from another cell; and means which transmits the instruction signal to the user device. The propagation loss is obtained from an average reception quality over a certain period and a required quality. Thus, only the user device which should follow the request for lowering the power from another cell lowers the transmission power, thereby uniformizing other cell interference.
