Abstract

무선 통신 시스템에서 단말(UE; User Equipment)에 의해 수행되는 비주기적(aperiodic) 사운딩 참조 신호(SRS; Sounding Reference Signal) 전송 방법 및 장치가 제공된다. 단말은 복수의 상향링크(UL; Uplink) 구성 반송파(CC; Component Carrier) 중 특정 UL CC를 통해 비주기적 SRS를 전송한다. 상기 특정 UL CC는 상향링크 그랜트(uplink grant)에 의해 스케줄링되는 PUSCH(Physical Uplink Shared Channel)가 전송되는 UL CC와 동일한 UL CC이며, 상기 상향링크 그랜트는 상기 비주기적 SRS의 전송을 트리거(trigger)하는 메시지를 포함한다.
