BASE STATION AND MOBILE STATION AND COMMUNICATION SYSTEM AND BASE STATION COMMUNICATION METHOD AND BASE STATION COMMUNICATION PROGRAM AND MOBILE STATION COMMUNICATION METHOD AND MOBILE STATION COMMUNICATION PROGRAM

摘要

Operational characteristics of a transmission system amplifier are controlled from a maximum transmission power value required at the transmitting position of a mobile station (100) and power consumption of the transmission system amplifier is suppressed thus increasing the communication time. A base station (900) monitors the transmitting position and the receiving quality of the mobile station (100) and determines a maximum transmission power required at the transmitting position by statistic processing or prediction. Based on the required maximum transmission power, the mobile station (100) controls the operational characteristics of the amplifier such that the required maximum transmission power can be delivered.
