Abstract

무선통신 시스템에서 수신기의 HARQ (hybrid automatic repeat request) 수행방법을 제공한다. HARQ 수행 방법은 연속하는 복수의 서브프레임들로 구성된 TTI(Transmission Time Interval) 단위로 데이터를 수신하는 단계 및 상기 데이터의 수신에 대한 ACK/NACK을 전송하는 단계를 포함하되, 상기 데이터는 상기 복수의 서브프레임에 각각 할당된 복수의 리던던시 버전으로 수신되고, 상기 ACK/NACK은 복수의 리던던시 버전 가운데 특정 리던던시 버전의 전송 시점으로부터 미리 결정된 처리지연 이후에 전송된다.
