Filed: 1998-06-05
Abstract: 통신 시스템에서 기지국들에 의해 송신되는 신호의 전력 레벨들이 제어된다.  전력 레벨 제어 명령들은 원격 스테이션으로부터 기지국들에 의해 송신되는 신호들의 전력 레벨들을 제어하도록 원격 스테이션이 신호들을 수신하는 기지국에 전송된다.  원격 스테이션이 실질적으로 동일한 메시지 정보를 포함하는 적어도 하나의 제2 기지국으로부터의 적어도 하나의 제2 신호 및 제1 기지국으로부터의 제1 신호를 동시에 수신하는지 여부에 대한 판정이 이루어진다.  제1 및 제2 기지국은 각각 제1 및 제2 신호들의 제1 및 제2 리포트들을 제어기에 송신한다.  이 제어기는 제1 및 제2 리포트들을 비교하여 제1 및 제2 신호들의 전력 레벨들을 조정하기 위한 제1 및 제2 명령들을 각각 제1 및 제2 기지국들에 송신한다.  전력 레벨 제어 명령들은 매크로다이버시티 동안에 원격 스테이션으로부터 기지국들로 보다 덜 빈번하게 송신되어 제어기와 기지국들 간의 시그널링 요구도를 감소시킨다.  또한, 제어기에 의한 제1 및 제2 신호들의 전력 레벨들의 조정의 스텝 사이즈가 매크로다이버시티 동안에 감소되어 시그널링 요구도를 감소시킨다.  이러한 전력 제어 방법은 특히 CDMA 시스템에 유리하다.
