Abstract

본 발명의 일 실시예에 따른 무선 통신 시스템에서 단말이 상향링크 신호를 송신하는 방법은, 전력 부스팅(boosting) 지시자를 포함하는 하향링크 제어 정보를 수신하는 단계; 상기 전력 부스팅 지시자에 기반하여 전력 부스팅이 적용되는 제1 심볼의 제1 송신 전력과 전력 부스팅이 적용되지 않는 제2 심볼의 제2 송신 전력을 각각 결정하는 단계; 및 상기 제1 송신 전력 및 상기 제2 송신 전력에 따라서 상향링크 신호를 송신하는 단계를 포함하고, 상기 전력 부스팅 지시자는, 상기 제1 심볼과 상기 제2 심볼 간의 간격이 일정 거리 이하이고, 상기 제1 송신 전력과 상기 제2 송신 전력 간의 차이가 일정 전력 오프셋 이상인 경우에 활성화된다.
