Abstract

본 발명에서는 상향링크 CoMP(Coordinative Multi-Point) 시스템에서 단말이 사운딩 참조 신호를 전송하는 방법이 개시된다. 구체적으로, CoMP 세트에 포함된 서빙 기지국으로부터 사운딩 참조 신호 전송을 위한 파라미터를 수신하는 단계, 상기 파라미터에 기반하여 상기 사운딩 참조 신호를 위한 자원을 할당하는 단계, 및 상기 할당된 자원에 따라 상기 CoMP 세트에 포함된 상기 서빙 기지국 및 하나 이상의 인접 기지국으로 상기 사운딩 참조 신호를 전송하는 단계를 포함하며, 상기 파라미터 중 상기 사운딩 참조 신호를 위한 기저 시퀀스(Basis Sequence)는 상기 CoMP 세트에 포함된 기지국 별로 다르게 설정되는 것을 특징으로 한다.
