Abstract:
(EN) The present invention relates to a method and an apparatus for performing beam management by a terminal in a wireless communication system. The present invention may provide a method and an apparatus in which a terminal receives, from a base station, configuration information of channel state information (CSI)-RS, and receives the CSI-RS on the basis of the configuration information, wherein the CSI-RS is transmitted through a plurality of antenna ports, and the terminal configures a beam of each of the plurality of antenna ports on the basis of the CSI-RS, wherein the CSI -RS is mapped to subcarriers on a frequency axis at an interval of predetermined number of resource elements (REs), and the CSI-RS is repeatedly transmitted according to the interval of the predetermined number of REs within a specific time period.
(FR) L'invention concerne un procédé et un appareil d'exécution de gestion de faisceau par un terminal dans un système de communication sans fil. L'invention peut fournir un procédé et un appareil dans lesquels un terminal reçoit, à partir d'une station de base, des informations de configuration d'informations d'état de canal (CSI-RS) et reçoit les CSI-RS sur la base des informations de configuration, les CSI-RS étant émises par l'intermédiaire d'une pluralité de ports d'antenne et le terminal configure un faisceau de chacun de la pluralité de ports d'antenne sur la base des CSI-RS, les CSI-RS étant mises en correspondance avec des sous-porteuses sur un axe de fréquence à un intervalle de nombre prédéfini d'éléments de ressource (RE) et les CSI-RS étant émises de manière répétée selon l'intervalle du nombre prédéfini de RE dans une période de temps spécifique.
(KO) 무선 통신 시스템에서 단말이 빔 관리 (beam management )를 수행하기 위한 방법 및 장지에 관한 것이다. 본 발명에 의하면, 단말은 기지국으로부터 CSI (Channel State 工 nformation) -RS으 | 설정 정보를 수신하고, 상기 설정 정보에 기초하여 상기 CSI -RS를 수신하되, 상기 CSI— RS는 복수의 안테나 포트들을 통해서 전송된다. 그리고, 단말은 상기 CSI -RS에 기초하여 상기 복수의 안테나 포트들 각각의 빔 (Beam)을 설정하되, 상기 CSI -RS는 일정 개수의 자원 요소 (Resource Element: RE) 간격으로 주파수 축 상의 서브 캐리어에 매핑되고, 상기 CSI -RS는 특정 시간 구간 내에서 상기 일정 개수의 상기 자원 요소 (Resource Element : RE) 간격에 따라 반복 전송되는 방법 및 장지를 제공할수 있다.
