Abstract:
1. 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, comprising: a transmission power measurement device in the mobile station and/or the base station measuring the transmission power; comparing the measured transmission power with predefined thresholds to determine whether an event happens; and if an event happens, reporting an event type to a rate adjustment controller at a network side, wherein the event type indicates that the measured transmission power exceeds at least one threshold or falls below at least one threshold; sending, by the rate adjustment controller, a rate adjustment demand according to the event type; and starting, by the rate adjustment controller, a timer in the rate adjustment controller; receiving, by the mobile station and/or the base station, the rate adjustment demand and adjusting the transmission rate, wherein if the mobile station adjusts the transmission rate, the transmission rate adjusted by the mobile station is the uplink transmission rate, and if the base station adjusts the transmission rate, the transmission rate adjusted by the base station is the downlink transmission rate; and sending, by the rate adjustment controller, another rate adjustment demand to the mobile station and/or base station if the timer expires and no other event type is reported.
