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 하향링크(DL; Downlink) 그랜트(grant)를 기반으로 결정되며, 상기 하향링크 그랜트는 상기 비주기적 SRS의 전송을 트리거(trigger)하는 메시지를 포함한다.
