Abstract

다중 분산 노드 시스템에서 채널 추정 방법 및 장치가 개시되어 있다. 채널 상태 추정 방법은 단말이 CSI-RS(channel state information reference signal) 설정 정보를 수신하는 단계와 단말이 상기 CSI-RS 설정 정보를 기초로 간섭량을 산출하고 상기 간섭량을 기초로 한 CSI(channel state information)를 송신하는 단계를 포함하되 CSI-RS 설정 정보는 외부 간섭 측정 필드 및 내부 간섭 측정 필드 중 적어도 하나의 필드를 포함할 수 있다. 따라서, 외부 간섭 및 내부 간섭을 측정함에 있어 간섭 측정에 사용되는 노드를 기지국에서 제어함에 따라 정확한 간섭량을 측정하여 정확한 채널 정보를 피드백할 수 있다.
