Abstract:
(EN) Disclosed in the present invention is a method by which a terminal reports channel status information (CSI) to a base station in a wireless communication system. The method comprises the steps of: receiving, through an upper layer, information on one CSI process having a first enhanced multiple input multiple output (eMIMO) type and a second eMIMO type; receiving a first channel status information-reference signal (CSI-RS) corresponding to the first eMIMO type; periodically reporting, to the base station, first CSI measured on the basis of the first CSI-RS; receiving a second CSI-RS, which corresponds to the second eMIMO type, beamformed on the basis of the first CSI; and periodically reporting, to the base station, second CSI measured on the basis of the second CSI-RS, wherein a priority of the first CSI is set to be equal to a priority of a CSI-RS resource indicator (CRI).
(FR) La présente invention concerne un procédé au moyen duquel un terminal rapporte des informations d’état de canal (CSI) à une station de base dans un système de communication sans fil. Le procédé comprend les étapes consistant à : recevoir, par l'intermédiaire d'une couche supérieure, des informations sur un processus CSI ayant un premier type d'entrée multiple sortie multiple améliorée (eMIMO) et un second type d'e MIMO ; recevoir un premier signal de référence d'informations d'état de canal (CSI-RS) correspondant au premier type d'e MIMO ; rapporter périodiquement, à la station de base, des premières CSI mesurées sur la base du premier CSI-RS ; recevoir un second CSI-RS, qui correspond au second type d'e MIMO, formé en faisceau sur la base des premières CSI ; et rapporter périodiquement, à la station de base, des secondes CSI mesurées sur la base du second CSI-RS, une priorité des premières CSI étant définie pour être égale à une priorité d'un indicateur de ressources CSI-RS (CRI).
(KO) 본 발명에서는 무선 통신 시스템에서 단말이 기지국으로 CSI (Channel Status Information)를 보고하는 방법이 개시된다. 상기 방법은 제 1 eMIMO (enhanced Multiple Input Multiple Output) 타입과 제 2 eMIMO 타입으로 구성되는 하나의 CSI 프로세스에 관한 정보를 상위 계층을 통하여 수신하는 단계; 상기 제 1 eMIMO 타입에 대응하는 제 1 CSI-RS (Channel Status Information-Reference Signal)를 수신하는 단계; 상기 제 1 CSI-RS 에 기반하여 측정된 제 1 CSI 를 상기 기지국으로 주기적으로 보고하는 단계; 상기 제 1 CSI에 기반하여 빔포밍된, 제 2 eMIMO 타입에 대응하는 제 2 CSI-RS를 수신하는 단계; 및 상기 제 2 CSI-RS에 기반하여 측정된 제 2 CSI 를 상기 기지국으로 주기적으로 보고하는 단계를 포함하고, 상기 제 1 CSI 의 우선 순위는 CRI (CSI-RS Resource Indicator)의 우선 순위와 동일하게 설정되는 것을 특징으로 한다.
