Abstract

본 발명에 따른 다중 셀 환경의 단말이 신호를 전송하는 방법은 기지국으로부터 부분 주파수 재사용 방식(fractional frequency reuse)에 따라 특정 주파수 파티션(frequency partition)을 할당받고, 기지국으로부터 상기 특정 주파수 파티션 또는 특정 주파수 파티션 내의 특정 자원 영역에 대한 변조 및 코딩 방식(MCS: Modulation and Coding Scheme) 레벨 정보를 수신받아 특정 주파수 파티션(frequency partition)이 인접 셀 경계에 위치하는 단말과 공유되는 주파수 파티션인지 여부 및 단말의 셀 내 위치에 따라 상기 MCS 레벨에 대응하는 전송 전력을 조정하고, 조정된 전송 전력으로 상기 기지국에 신호를 전송하는 방법에 관한 것이다.
