Abstract

본 명세서는 무선 접속 시스템에서, 제어 채널을 모니터링하는 방법에 있어서, 제어채널이 전송되는 공용 검색 공간(Common Search Space) 및 단말 특정 검색 공간(UE-specific Search Space) 각각에 대한 최대 블라인드 디코딩(blind decoding) 횟수를 설정하는 단계; 상기 검색 공간별 설정된 최대 블라인드 디코딩 횟수에 기초하여, 상기 검색 공간별로 복수의 후보 제어채널들에 대해 모니터링하는 단계; 및 상기 복수의 후보 제어채널들 중 블라인드 디코딩에 성공한 제어채널을 통해 하향링크 제어 정보를 수신하는 단계를 포함하되, 상기 공용 검색 공간은 적어도 하나의 컴포넌트 캐리어(Component Carrier)를 포함하는 적어도 하나의 캐리어 그룹에 할당되는 것을 특징으로 한다.
