| Zusammenfassung: | PURPOSE: A control method is provided to control electric power level of the forward direction electric power control bit and an electric power rate of a reverse direction pilot channel and a traffic channel to improve a communication quality and a decision function of the electric power control bit when it is soft off. CONSTITUTION: The method for controlling an electric power ration between channels includes two modes. A first mode is a normal mode. A second mode is a soft hand off mode. The normal mode is that a terminal of a communication system communicates with a designated first base station after establishing a pilot of a reverse direction link and a relative electric power ratio of a traffic channel with a designated level. The soft hand off mode is that the terminal communicates with a plurality of second base stations through a change of the electric power ratio.
본 발명은 무선통신 채널의 전력비 제어방법에 관한 것으로, 통신시스템의 단말기가 역방향 링크의 파일롯 채널과 트래픽 채널의 상대적인 전력비를 소정의 레벨로 설정하여 소정의 제 1 기지국과 교신하는 정상모드와, 단말기가 전력비를 변경하여 복수개의 제 2 기지국과 교신하는 소프트 핸드오프모드로 이루어져 소프트 핸드오프 모드일 때, 역방향 파일롯 채널과 트래픽 채널의 전력비를 정상모드보다 작게 조절함으로써, 동기복조의 성능이 향상되는 효과가 있다. |
