Abstract

본 발명은 제어채널에서 사용되는 정보 비트의 크기를 조정하는 방법들 및 이를 수행하는 장치를 개시한다. 또한, 본 발명은 크기가 조정된 정보 비트를 포함하는 제어채널을 검색하는 방법들을 개시한다. 본 발명의 일 실시예로서 멀티캐리어를 지원하는 무선접속시스템에서 물리하향링크제어채널(PDCCH)을 수신하는 방법은, PDCCH를 검색하기 위해서 단말에 할당된 서치 스페이스에서 블라인드 디코딩을 수행하는 단계와 서치스페이스에서 크기가 조정된 하향링크 제어정보(DCI)를 포함하는 PDCCH를 수신하는 단계를 포함할 수 있다. 이때, 크기가 조정된 DCI는 단말에 할당된 대역폭, 단말에 할당된 컴포넌트 캐리어(CC)의 전송모드 및 단말의 안테나 개수 중 하나 이상을 고려하여 크기가 조정될 수 있다.
