Abstract

본 발명의 일 양상은 동일한 하향링크/상향링크 자원에 할당된 사용자기기별로 상향링크/하향링크 ACK/NACK 정보의 전송 자원을 달리하기 위하여, 사용자기기별로 특정하게 정의된 값을 상향링크/하향링크 ACK/NACK 채널의 자원 할당/맵핑시에 반영한다. 본 발명의 다른 양상은 동일한 하향링크/상향링크 자원에 할당된 사용자기기별로 상향링크/하향링크 ACK/NACK 정보를 전송하는 노드를 달리한다. 본 발명에 의하면, 다수의 사용자기기들에 대한 하향링크/상향링크 신호가 동일 자원에서 전송되더라도, 상기 다수 사용자기기의 상향링크/하향링크 ACK/NACK 신호는 서로 다른 자원에서 전송되어, 상기 다수 사용자기기의 ACK/NACK 신호 간의 간섭을 줄일 수 있게 된다.
