Abstract

무선 통신 시스템에서 피드백 전송 방법 및 장치가 제공된다. 단말은 기지국으로부터 단기 피드백 주기(short-term feedback period) 및 장기 피드백 주기(long-term feedback period)에 관한 정보를 수신하고, 상기 기지국으로 상기 단기 피드백 주기마다 단기 피드백 정보를 또는 상기 장기 피드백 주기마다 장기 피드백 정보를 1차 패스트 피드백 채널(PFBCH; Primary Fast Feedback Channel) 상으로 전송한다. 상기 장기 피드백 정보는 채널 측정의 대상이 되는 서브밴드(subband)의 인덱스 및 기준 채널 측정값과 측정된 채널 측정값의 차이인 차이 측정값을 포함한다.
