Abstract

TDD(Time Division Duplex) 기반 무선 통신 시스템에서 ACK/NACK 전송 방법 및 장치가 제공된다. 단말이 제1 서빙셀로부터 M 하향링크 서브프레임에서 영 또는 그 이상의 하향링크 전송 블록을 수신하고, 상기 제1 서빙셀에 대한 ACK/NACK 상태 {HARQ-ACK(1),HARQ-ACK(2),HARQ-ACK(3),HARQ-ACK(4)}를 결정한다. 단말이 상기 ACK/NACK 상태를 기반으로 ACK/NACK 응답을 결정하고, 상기 상향링크 서브프레임에서 상기 ACK/NACK 응답을 전송한다.
