Title (EN) METHOD FOR REPORTING CHANNEL STATE IN WIRELESS COMMUNICATION SYSTEM AND DEVICE THEREFOR
(FR) PROCÉDÉ POUR RAPPORTER UN ÉTAT DE CANAL DANS UN SYSTÈME DE COMMUNICATION SANS FIL ET DISPOSITIF ASSOCIÉ
(KO) 무선 통신 시스템에서 채널 상태 보고를 위한 방법 및 이를 위한 장치
Abstract:
(EN) According to one embodiment of the present invention, a method by which a terminal reports a channel state on the basis of a channel state information-reference signal (CSI-RS) in a wireless communication system can comprise the steps of: transmitting, to a base station, terminal capability information related to the maximum number of CSI processes which can be simultaneously updated or calculated by the terminal in which a shortened processing time has been set; receiving an aperiodic CSI request from the base station; and, according to the aperiodic CSI request, updating or calculating CSI in a CSI reference resource at the point of time set for the shortened processing time, on the basis of the terminal capability information and transmitting the updated or calculated CSI to the base station.
(FR) Selon un mode de réalisation de la présente invention, un procédé par lequel un terminal rapporte un état de canal sur la base d'un signal de référence d'informations d'état de canal (CSI-RS) dans un système de communication sans fil peut comprendre les étapes consistant à: transmettre, à une station de base, des informations de capacité de terminal relatives au nombre maximal de processus CSI qui peuvent être simultanément mis à jour ou calculés par le terminal dans lequel un temps de traitement raccourci a été défini; recevoir une demande de CSI apériodique en provenance de la station de base; et, selon la demande de CSI apériodique, mettre à jour ou calculer des CSI dans une ressource de référence de CSI au moment défini pour le temps de traitement raccourci, sur la base des informations de capacité de terminal et transmettre les CSI mises à jour ou calculées à la station de base.
(KO) 본 발명의 일 실시예에 따른 무선 통신 시스템에서 채널 상태 정보-참조 신호(channel state information-reference signal; CSI-RS) 기반의 채널 상태 보고 방법에 있어서, 상기 방법은 단말에 의해 수행되고, 프로세싱 시간 감소(shortened processing time)가 설정된 상기 단말이 동시에 갱신 또는 계산할 수 있는 최대 CSI 프로세스의 수에 관한 단말 능력(capability) 정보를 기지국으로 전송하는 단계; 상기 기지국으로부터 비주기적 CSI 요청을 수신하는 단계; 및 상기 비주기적 CSI 요청에 따라 상기 단말 능력 정보에 기초하여 상기 프로세싱 시간 감소를 위해 설정된 시점의 CSI 기준 자원에서 CSI를 갱신 또는 계산하고, 상기 갱신 또는 계산된 CSI를 상기 기지국으로 전송하는 단계를 포함할 수 있다.
