Abstract

중계기의 중계기가 특정 하향링크 서브프레임 및 특정 상향링크 서브프레임을 통해 신호를 송수신하는 방법이 개시된다. 중계기는 기지국과 신호를 송수신하기 위한 서브프레임 타이밍 설정을 위해 상기 기지국과 상기 중계기의 거리에 따른 전파 지연을 고려할 수 있다. 중계기는 하향링크 수신 타이밍을 설정하는 경우 상기 전파 지연 시간 외에 0.5개 심볼, 1개 심볼 등의 지연시간을 더 고려할 수 있다. 중계기의 상향링크 서브프레임 타이밍을 설정하는 경우는 백홀 링크를 기준으로 설정하는 경우와 액세스 링크를 기준으로 설정하는 경우로 구분할 수 있다. 액세스 링크를 기준으로 하는 경우에는 백홀 링크를 기준으로 하는 경우보다 전파 지연이 2배가 될 수 있기 때문에 이를 고려하여 타이밍을 설정할 필요가 있다.
