Abstract

본 발명은 무선통신 시스템에 관한 것으로, 보다 상세하게는 제어정보를 전송하는 방법 및 장치에 관한 것이다. 무선통신 시스템은 반송파 병합(Carrier Aggregation: CA)을 지원할 수 있다. 본 발명의 일 측면에서는 무선 통신 시스템에서 단말이 제어정보를 기지국으로 전송하는 방법에 있어서, 상기 기지국으로부터 상기 단말에 구성된 적어도 하나의 서빙 셀을 통해 PDCCH(Physical Downlink Control Channel) 및 PDSCH(Physical Downlink Shared CHannel) 중 적어도 하나를 수신하는 단계와 상기 PDCCH 수신 또는 상기 PDCCH가 지시하는 PDSCH 수신에 대한 제어정보를 상기 기지국으로 전송하는 단계를 포함하되, 상기 적어도 하나의 서빙 셀은 FDD(Frequency Division Duplex) 프레임 구조 또는 TDD(Time Division Duplex) 프레임 구조를 이용하고, 상기 제어정보는 상기 적어도 하나의 서빙 셀 중 기 설정된 기준에 따라 결정된 제 1 서빙 셀의 제어정보 피드백 타이밍(timing)을 이용하여 전송될 수 있다.
