Abstract

다중안테나 시스템에서 데이터 전송방법은 복수의 안테나를 포함하는 제1 안테나 클러스터(cluster) 및 제2 안테나 클러스터에 채널 종속적 프리코딩(precoding)을 적용하여 송신 신호를 생성하되, 상기 채널 종속적 프리코딩은 각 안테나 클러스터에 대한 프리코딩 가중치가 블록 다이아고날(block diagonal) 형태로 구성되는 프리코딩 가중치 행렬에 의해 수행되고, 상기 프리코딩 가중치는 각 안테나 클러스터에 포함되는 송신 안테나 수 P 및 각 안테나 클러스터에 적용되는 계층 수 V에 대한 P×V로 표현되는 단계(P, V>0인 정수), 및 상기 송신 신호를 전송하는 단계를 포함한다.
