Abstract

본 발명은 무선 통신 시스템에 관한 것이다. 구체적으로, 본 발명은 무선 통신 시스템에서 단말이 신호를 전송하는 방법에 있어서, 복수의 콤포넌트 반송파에 대해 콤포넌트 반송파별 최대 전송 전력(P_CC_MAX) 및 상기 단말의 최대 전송 전력(P_UE_MAX)을 확인하는 단계; 하나 이상의 콤포넌트 반송파를 통해 기지국으로 동시에 전송되도록 예정된 복수의 채널에 대해 각각의 전송 전력을 계산하는 단계; 상기 P_CC_MAX 및 상기 P_UE_MAX를 초과하지 않도록 상기 복수의 채널에 대해 전송 전력을 독립적으로 조정하는 단계; 및 상기 전송 전력이 조정된 복수의 채널을 통해 상기 기지국으로 신호를 전송하는 단계를 포함하는 신호 전송 방법에 관한 것이다.
