Abstract

다중안테나 시스템에서 데이터 전송방법은 복수의 안테나를 포함하는 제1 안테나 클러스터(cluster) 및 제2 안테나 클러스터에 프리코딩 가중치 행렬을 적용하여 상기 복수의 안테나에서의 송신 신호를 생성하되, 상기 프리코딩 가중치 행렬은 상기 제1 안테나 클러스터 및 상기 제2 안테나 클러스터 각각에 대응하는 프리코딩 가중치로 구성되는 블록 다이아고날(block diagonal) 형태의 행렬이고, 상기 제1 안테나 클러스터의 프리코딩 가중치는 채널 상황에 따라 선택되고, 상기 제2 안테나 클러스터의 프리코딩 가중치는 채널 상황과 무관하게 일정한 규칙에 따라 선택되는 단계, 및 상기 송신 신호를 전송하는 단계를 포함한다.
