Abstract

무선통신 시스템에서 소스국(source station)이 HARQ(hybrid automatic repeat request)를 수행하는 방법은 전송 시점에 목적국(destination station)으로 데이터를 전송하는 단계; 상기 전송 시점으로부터 제1 전송간격 후에 상기 데이터에 대한 ACK(acknowledgement) 또는 NACK(Negative-acknowledgement)신호를 상기 목적국으로부터 수신하는 단계; 및 상기 NACK신호를 수신하는 경우, 상기 전송 시점으로부터 제2 전송간격 후에 상기 데이터를 재전송하는 단계를 포함하되, 상기 제2 전송간격은 미리 정해진 복수의 전송간격 중 선택된 하나의 전송간격인 것을 특징으로 한다. 무선통신 시스템에서 HARQ 주기, ACK/NACK 전송 시점 등이 서로 다른 이질적인 HARQ를 수행할 수 있다.
