Abstract

본 발명은 캐리어 결합 환경에서 하나 이상의 서빙셀에 대한 채널상태정보를 전송하는 다양한 방법들 및 이를 지원하는 장치들을 개시한다. 본 발명의 일 실시예로서 캐리어 결합을 지원하는 무선 접속 시스템에서 채널상태정보(CSI)를 보고하는 방법은, 단말이 기지국으로부터 하나 이상의 서빙 셀에 대한 CSI 보고 모드와 관련된 정보를 수신하는 단계와 단말이 CSI 보고 모드를 고려하여 하나 이상의 서빙 셀에 대한 채널상태정보(CSI)를 기지국으로 보고하는 단계를 포함할 수 있다. 이때, 제 1 서빙셀에 대한 제 1 타입 CSI와 제 2 서빙셀에 대한 제 2 타입 CSI가 동일 서브프레임에서 전송되는 경우에는, 단말은 CSI 보고 모드와 관련된 CSI 보고 타입의 우선순위에 따라 하나의 서빙셀에 대한 CSI만을 기지국에 보고할 수 있다.
