Method for controlling packet rate in a mobile communication system

A method for determining a data rate of next reverse packet data according to ACK/NACK information and rate control information received from a plurality of base stations in a mobile communication system, transmits reverse packet data to the base stations, and each of the base stations transmits ACK/NACK information and rate control information, indicating a rate-up, rate-down, or rate-bold command, to the mobile station in response to the reverse packet data. The mobile station determines a data rate of reverse packet data based on rate control information received from a set of base stations that excludes base stations that transmitted rate control information indicating a rate-bold command together with NACK information and transmits the packet data at the determined data rate.
