Abstract

이동통신 시스템의 상향링크 송신 전력 제어 방법이 개시된다. 서로 인접한 두 셀에 각각 위치하는 제1 기지국 및 제2 기지국을 포함하는 이동통신 시스템에서 제1 및 제2 기지국 중 적어도 하나의 기지국이 송신전력의 서브프레임 오프셋(SOTP: Subframe Offset of Transmit Power)을 생성하고, 제1 및 제2 기지국 중 적어도 하나의 기지국이 생성된 송신전력의 서브프레임 오프셋을 해당 셀에 속한 적어도 하나의 단말에게 전송한다. 따라서, 송신 전력 제어를 위한 시그널링 회수를 감소시킬 수 있고, 정확한 송신 전력 제어를 수행할 수 있다.
