Abstract

무선 통신 시스템에서 채널 상태 정보를 보고하는 방법 및 이를 위한 장치가 개시된다. 본 발명의 일례에 따른 무선 통신 시스템에서 단말이 채널 상태 정보(CSI)를 보고하는 방법은, 기지국으로부터 제1 방향 도메인에 대한 적어도 하나의 CSI-RS 설정(CSI-reference signal configuration)을 포함하는 RRC 메세지를 수신하는 단계; 상기 CSI-RS 설정에 기초하여, 상기 기지국의 다수의 물리 안테나 소자들 중 제1 서브셋으로부터의 제1 CSI-RS 및 제2 서브셋으로부터의 제2 CSI-RS를 각각 서로 다른 서브프레임들을 통해 수신하는 단계; 상기 제1 및 제2 CSI-RS들을 이용하여 CSI 보고를 수행하는 단계를 포함하고, 상기 제1 방향 도메인에 대한 상기 CSI-RS 설정이 하나인 경우, 상기 하나의 CSI-RS 설정에 관련된 안테나 포트들이 소정의 주기에 따라서 가상화 변경(virtualization varying)됨에 따라서 상기 제1 CSI-RS 및 상기 제2 CSI-RS를 각각 상기 제1 서브셋 및 상기 제2 서브셋으로부터 수신한다.
