PURPOSE: A method for controlling a transmission rate of a reverse channel in a mobile communication system is provided to determine a transmission rate of an R-CQICH(Reverse Channel Quality Indicator Channel) in a forward transmission end, and to control the transmission rate by transmitting the determined rate, thereby freely controlling the transmission rate of the R-CQICH. CONSTITUTION: A base station obtains information on power assigned to a packet data service(200). The base station obtains information on the number of Walsh codes assigned to the packet data service(202). The base station obtains information on interferences of an R-CQICH received from a terminal(204). The base station obtains information on a kind of the packet data service of the terminal(206). The base station obtains information on the number of entire terminals(208). The base station determines a transmission rate of the R-CQICH by using the obtained information, and transmits the determined transmission rate to the terminals(210). 본 발명에 따른, 고속데이터 서비스와 음성 서비스를 함께 지원하는 이동통신시스템에서, 기지국이 순방향 채널상태 정보를 전송하기 위한 역방향 채널품질지시채널(R-CQICH)의 전송율을 결정하여 송신하기 위한 방법이, 패킷 서비스를 위해 사용가능한 전력량 및 측정된 역방향 채널품질지시채널의 간섭량에 근거하여 상기 역방향 채널품질지시채널의 전송율을 결정하는 과정과, 상기 결정된 역방향 채널품질지시채널의 전송률을 단말에게 전송하는 과정을 포함한다.
