Abstract

본 발명은 무선 통신 시스템에 관한 것이다. 구체적으로, 본 발명은 주파수 집성(carrier aggregation)을 지원하는 무선 통신 시스템에서 기지국이 콤포넌트 반송파(Component Carrier)를 설정하는 방법에 있어서, 하향링크 콤포넌트 반송파에 대한 단말의 초기 접속 허용 여부를 결정하는 단계; 상기 하향링크 콤포넌트 반송파를 통해 동기 채널 및 방송 채널을 하나 이상의 단말에게 전송하는 단계를 포함하되, 상기 초기 접속 허용 여부는 상기 동기 채널 및 상기 방송 채널 중 적어도 하나를 변형함으로써 상기 하나 이상의 단말에게 적용되는 콤포넌트 반송파 설정 방법에 관한 것이다.
