Abstract

본 발명은 일 실시예는, 무선통신시스템에서 신호를 송수신하는 방법에 있어서, 제1 전송포인트가 하나 이상의 서브프레임에서 주파수 자원 영역을 설정하는 단계; 및 상기 설정된 주파수 자원 영역에 관련된 정보를 제2 전송포인트로 전송하는 단계를 포함하며, 상기 제1 전송포인트가 상기 주파수 자원 영역에서 PDSCH(Physical Downlink Shared Channel)를 전송하는 경우, 상기 주파수 자원 영역에서의 PDSCH EPRE(Energy Per Resource Element) 대 CRS(Cell-specific reference signal) EPRE는, 상기 주파수 자원 영역 이외의 자원 영역에서의 PDSCH EPRE 대 CRS EPRE보다 작은 값이 사용되는, 신호 송수신 방법이다.
