Apparatus and method for controlling reverse link data rate of packet data in a mobile communication system

PURPOSE: A method for controlling a reverse data rate of packet data in a mobile communication system and a method therefor are provided to transmit state report information to a base station, so that the base station can control a reverse data rate of a mobile station. CONSTITUTION: A mobile station maintains state report information(400), and checks whether a state report update period comes(402). If so, the mobile station checks whether a current transmission buffer has more than a threshold value(408). If so, the mobile station sets a buffer indicator to '0'(410). The mobile station checks whether an increase of a transmission power is available(414). If so, the mobile station sets a power indicator to '0'(416). The mobile station updates the state report information into the set value produced from the step '416' or '418'(420).
