Abstract
(EN) A method for reporting channel state information (CSI) by a terminal in a wireless communication system according to an embodiment of the present specification comprises the steps of: receiving configuration information related to channel state information (CSI); receiving a downlink reference signal (DL RS); calculating the CSI on the basis of the DL RS; and reporting the CSI. A resource set related to measurement of the DL RS is determined to be one specific resource set or multiple specific resource sets on the basis of downlink control information (DCI) by which reporting of the CSI is triggered.
(FR) Selon un mode de réalisation de la présente invention, un procédé de rapport d'informations d'état de canal (CSI) par un terminal dans un système de communication sans fil comprend les étapes consistant à : recevoir des informations de configuration relatives aux informations d'état de canal (CSI) ; recevoir un signal de référence de liaison descendante (DL RS) ; calculer les CSI sur la base du DL RS ; et rapporter les CSI. Un ensemble de ressources lié à la mesure du RS DL est déterminé comme étant un ensemble de ressources spécifiques ou de multiples ensembles de ressources spécifiques sur la base d'informations de commande de liaison descendante (DCI) qui déclenchent le rapport des CSI.
(KO) 본 명세서의 일 실시예에 따른 무선 통신 시스템에서 단말이 채널 상태 정보(Channel State Information, CSI)를 보고하는 방법은 채널 상태 정보(Channel State Information, CSI)와 관련된 설정 정보를 수신하는 단계, 하향링크 참조 신호(Downlink Reference Signal, DL RS)를 수신하는 단계, 상기 DL RS에 기초하여 상기 CSI를 계산하는 단계 및 상기 CSI를 보고하는 단계를 포함한다. 상기 CSI의 보고를 트리거 하는 하향링크 제어 정보(Downlink Control Information, DCI)에 기반하여, 상기 DL RS의 측정과 관련된 자원 세트가 하나의 특정 자원 세트 또는 복수의 특정 자원 세트들로 결정되는 것을 특징으로 한다.
