Abstract: front page image
(EN)A method by which a base station transmits a reference signal to a terminal in a wireless communication system is disclosed. Particularly, the method comprises the steps of: determining a reference signal resource interval expressed as a unit of one or more resource blocks (RBs); setting reference signal resources for a downlink bandwidth defined by a plurality of RBs, according to the reference signal resource interval; and transmitting the reference signal to the terminal by using the set reference signal resources, wherein the reference signal resource interval is determined on the basis of the number of reference signal antenna ports for which quasi co-location (QCL) can be assumed.
(FR)La présente invention porte sur un procédé par lequel une station de base émet un signal de référence à un terminal dans un système de communication sans fil. En particulier, le procédé comprend les étapes consistant à: déterminer un intervalle de ressources de signal de référence exprimé sous la forme d'une unité d'un ou plusieurs blocs de ressources (RB); régler des ressources de signal de référence pour une largeur de bande de liaison descendante définie par une pluralité de RB, en fonction de l'intervalle de ressources de signal de référence; et émettre le signal de référence au terminal par utilisation des ressources de signal de référence réglées, l'intervalle de ressources de signal de référence étant déterminé sur la base du nombre de ports d'antenne de signal de référence pour lesquels une quasi colocalisation (QCL) peut être supposée.
(KO)본 출원에서는 무선 통신 시스템에서 기지국이 단말로 참조 신호를 송신하는 방법이 개시된다. 구체적으로, 상기 방법은, 하나 이상의 자원 블록 (Resource Block; RB) 단위로 표현되는 참조 신호 자원 간격을 결정하는 단계; 복수의 자원 블록들로 정의되는 하향링크 대역폭에 상기 참조 신호 자원 간격에 따라 참조 신호 자원을 설정하는 단계; 및 상기 설정된 참조 신호 자원을 이용하여 상기 단말로 상기 참조 신호를 송신하는 단계를 포함하고, 상기 참조 신호 자원 간격은 QCL (Quasi Co-Location) 가정이 가능한 참조 신호 안테나 포트의 개수에 기반하여 결정되는 것을 특징으로 한다.
