摘要： Disclosed is a method for controlling uplink and/or downlink transmission rate between a mobile station and a base station according to transmission power of the mobile station/base station in a communication system. First, a transmission power measurement device measures transmission power of the mobile station/base station. Then, the transmission power measurement device compares the measured transmission power with predefined thresholds to determine whether an event happens. At last, if an event happens, a rate adjustment controller sends a rate adjustment demand according to type of the event to adjust the uplink and/or downlink transmission rate.
