Abstract
이동국이 기지국으로 임의 접속 절차 중 하향링크 패킷들의 복합 자동 재전송 요청 동작을 위한 방법이 개시된다. 기지국은 수신된 임의 접속용 프리앰블에 기지국 내에서 식별자를 할당하고, 식별자 정보와 상향링크 제어 정보를 포함하는 응답 메시지를 이동국으로 전송한다. 기지국은 이동국의 고유 식별자를 포함하는 접속 요청 메시지를 상향링크 채널을 통해 수신하여, 고유 식별자를 이용하여 이동국에 하향링크의 확인 채널을 할당한다. 또한, 기지국은 접속 요청 메시지에 대한 접속 설정 메시지와 하향링크의 확인 채널에 대한 정보를 이동국으로부터 전송하고, 확인 채널을 통해 접속 설정 메시지에 대한 확인 메시지를 수신한다.
