Abstract
본 발명은 향상된 물리하향링크제어채널(E-PDCCH)을 검색하는 방법들 및 이를 지원하는 장치들을 개시한다. 본 발명의 일 실시예로서 무선접속시스템에서 향상된 물리하향링크제어채널 (E-PDCCH)을 검색하는 방법은, 제어채널영역을 블라인드 디코딩하여 레거시 물리하향링크제어채널 (PDCCH)을 검색하는 단계와 검색한 레거시 PDCCH를 기반으로 상기 E-PDCCH를 검색하는 단계를 포함할 수 있다. 이때, 레거시 PDCCH는 E-PDCCH가 할당되는 서브프레임에서는 항상 해당 서브프레임의 첫 번째 심볼부터 세 번째 심볼 모두를 사용하여 할당되는 것이 바람직하다.
