Abstract

본 명세서는 연계된 다중전송단 방식을 지원하는 제어정보의 전송장치 및 방법에 관한 것이다. 이러한 본 명세서는 코드워드의 전송에 사용되는 레이어의 개수를 결정하고, 상기 코드워드에 대한 채널을 추정하는 복조 기준신호의 전송에 사용되는 안테나 포트를 결정하며, 상기 결정된 개수의 레이어를 나타내는 다중 레이어 지시자 및 상기 안테나 포트에 관한 정보를 포함하는 하향링크 제어정보(DCI)를 생성하는 DCI 생성부, 전송블록을 상기 코드워드에 맵핑하고, 상기 맵핑된 코드워드를 상기 결정된 개수의 레이어에 맵핑하며, 상기 복조 기준신호를 적어도 하나의 안테나 포트에 맵핑하는 데이터 처리부, 및 상기 하향링크 제어정보를 물리하향링크제어채널(PDCCH)에 맵핑하고, 상기 레이어 맵핑된 코드워드를 물리하향링크공용채널(PDSCH)에 맵핑하며, 상기 PDCCH, 상기 PDSCH 및 상기 복조 기준신호를 단말로 전송하는 하향링크 전송부를 포함하는 기지국을 개시한다. 본 발명에 따르면, 블라인드 디코딩 복잡도를 증가시키지 않고도 하향링크에서 단일 셀 MIMO와 연계된 다중전송단 방식 모두 지원할 수 있고, 단일 셀 MIMO와 연계된 다중전송단 방식간에 동적인 스위칭을 지원할 수 있다.
