Abstract: front page image
(EN)The present invention relates to a wireless communication system, and more specifically, to a method and an apparatus for transmitting an RS (Reference Signal) from a transmission end. The present invention relates to an RS transmission method and an apparatus therefor, comprising the steps of: confirming RS resources which are defined according to each layer; and transmitting the precoded RS for the layers to a receiving end through a multiple antenna, wherein the RS resource includes a 1st index for indicating an RS resource pattern group in which the precoded RS is mapped within a resource block and a 2nd index for indicating a code resource for multiplexing the precoded RSs within the RS resource pattern group.
(FR)L'invention concerne un système de communication sans fil, et plus spécifiquement un procédé et un dispositif de transmission d'un signal de référence (RS) à partir d'une extrémité de transmission. L'invention concerne un procédé et un dispositif de transmission de RS qui comprend les étapes consistant à: confirmer les ressources RS définies selon chaque couche; et transmettre à une extrémité de réception le RS précodé des couches par l'intermédiaire d'une antenne multiple, la ressource RS comprenant un premier indice indiquant un groupe de motifs de ressources de RS dans lequel le RS précodé est mappé dans un bloc de ressources, et un deuxième indice indiquant une ressource de code pour multiplexer les RS précodés du groupe de motifs de ressources de RS.
(KO)본 발명은 무선 통신 시스템에 관한 것이다. 구체적으로, 본 발명은 무선 통신 시스템에서 송신단이 참조 신호(Reference Signal; RS)를 전송하는 방법 및 장치에 관한 것으로서, 레이어(layer) 별로 정의된 RS 자원을 확인하는 단계; 및 상기 RS 자원을 이용하여, 레이어를 위한 프리코딩 된 RS를 다중 안테나를 통해 수신단으로 전송하는 단계를 포함하고, 상기 RS 자원은 자원블록(resource block) 내에서 상기 프리코딩 된 RS가 맵핑되는 RS 자원 패턴 그룹을 지시하는 제1 인덱스와 상기 프리코딩 된 RS를 상기 RS 자원 패턴 그룹 내에 다중화하기 위한 코드 자원을 지시하는 제2 인덱스를 포함하는 RS 전송 방법 및 이를 위한 장치에 관한 것이다.
