Abstract
This invention is to prevent deterioration in communication quality of closed loop transmission power control, which may occur when the change in transmission power cannot keep up with a sudden change in the state of a transmission path. Transmission power control command extractorextracts a transmission power control command from the uplink signal that has been received by receiverMobile position predictorpredicts the future position of the mobile station from its present position as recognized by mobile position recognizerand from its present rate of movement as recognized by mobile velocity recognizerDatabaserecords the state of the downlink transmission path as a function of mobile position. Transmission power controllerlooks up databaseon the basis of the predicted future position of the mobile station and controls the downlink transmission power of base station BS on the basis of (i) the result of this lookup, and (ii) the transmission power control command. Transmittertransmits at the downlink transmission power that has been instructed by transmission power controller
