Abstract

무선통신 시스템에서 단말이 비주기적(aperiodic) 사운딩 참조신호(Sounding Reference Signal, SRS) 트리거링에 기반하여 SRS를 전송하는 방법과 비주기적 SRS를 전송하기 위한 상향링크 전송 전력을 제어하는 방법이 개시된다. 본 발명에 따른 단말이 비주기적(aperiodic) 사운딩 참조신호(Sounding Reference Signal, SRS) 트리거링에 기반하여 SRS를 전송하는 방법은, 기지국으로부터 복수의 비주기적 SRS 구성(configuration) 정보를 수신하는 단계; 상기 기지국으로부터 비주기적 SRS 전송을 트리거링(triggering)하는 지시자를 수신하는 단계; 상기 비주기적 SRS 전송 트리거링 지시자를 수신한 서브프레임 인덱스, 상기 비주기적 SRS 전송 트리거링 지시자를 수신한 서브프레임 인덱스, 상기 비주기적 SRS 전송 트리거링 지시자의 수신 서브프레임과 대응되는 비주기적 SRS 전송 서브프레임 간의 시간 관계 및 상향링크 채널 상태 중 적어도 하나에 기초하여 상기 복수의 비주기적 SRS 구성 정보 중 특정 비주기적 SRS 구성 정보를 선택하는 단계; 및 상기 선택된 비주기적 SRS 구성 정보에 기초하여 상기 비주기적 SRS 전송 트리거링 지시자에 대한 비주기적 SRS를 전송하는 단계를 포함하되, 상기 복수의 비주기적 SRS 구성 정보는 상기 비주기적 SRS 전송 트리거링 지시자에 대응하여 비주기적 SRS를 전송하는 자원에 관한 정보를 포함할 수 있다. 또한, 본 발명에 따라, 단말은 기지국으로부터 비주기적 SRS 전송을 위한 전력 옵셋값을 수신하며 비주기적 SRS 전송을 위한 전송 전력값을 결정하는데 이용할 수 있다.
