METHOD FOR CONTROLLING THE DATA RATE OF A REVERSE LINK IN A COMMUNICATION SYSTEM, ESPECIALLY CONCERNED WITH ACCUMULATING CONTROL INFORMATION TRANSMITTED FROM A BASE STATION AND CONTROLLING THE DATA RATE OF A REVERSE LINK USING THE ACCUMULATED CONTROL INFORMATION

摘要

PURPOSE: A method for controlling the data rate of a reverse link in a communication system is provided to efficiently execute rate control by accumulating repeated control information and determining a data rate using the accumulated information, in the case of applying a rate control method to such an algorithm as an H-ARQ(Hybrid-Automatic Repeat Request) method. CONSTITUTION: A mobile station initializes the present data rate with a virtual data rate(S31), and receives control information, which includes a data transmission success status signal and rate control information, from a base station(S32). The mobile station updates the virtual data rate using the rate control information contained in the received control information(S33). The mobile terminal checks the data transmission success status signal, and determines the virtual data rate as a data rate if the data transmission success status signal indicates 'ACK'(S34). However, in case that the data transmission success status signal indicates 'NACK', the mobile station receives control information from the base station again(S32).
