Abstract

본 발명은 특히 다중 사용자 무선 전송 시스템에서 데이터 전송의 효율 향상을 위한 방법 및 장치에 대한 것이다. 본 발명의 일 실시 예에 따른 방법은, 다중 사용자 무선 통신 시스템에서 데이터의 전송 방법으로, 단말로부터 궤환(feedback) 정보 또는 사운딩(sounding)을 통하여 단말별로 채널 상태를 추정하여 각 단말로 개별적인 데이터를 동시에 전송할 단말을 선정하는 과정과, 상기 선정된 단말들의 수신 신호대 잡음비를 결정하고, 선부호화 매트릭스(precoding matrix)를 계산하는 과정과, 각 단말별로 부호화 및 변조 기법(MCS) 및 상기 각 단말별 MCS에 따른 데이터 필드(Data field)의 심볼 수를 계산하는 과정과, 선정된 단말이 둘 이상인 경우 상기 데이터 필드를 동시 전송할 단말의 수에 따라 영역을 구분하는 과정과, 각 단말의 각 영역별로 수신 신호대 잡음비(SINR)를 재계산하고, 이에 따른 MCS를 재설정하여 패킷을 구성하고 이를 전송하는 과정을 포함한다.
