Title (EN) METHOD FOR REPORTING CHANNEL STATE INFORMATION IN WIRELESS COMMUNICATION SYSTEM AND APPARATUS THEREFOR
(FR) PROCÉDÉ POUR RAPPORTER DES INFORMATIONS D'ÉTAT DE CANAL DANS UN SYSTÈME DE COMMUNICATION SANS FIL ET APPAREIL ASSOCIÉ

Abstract:
(EN) The present specification provides a method for reporting CSI in a wireless communication system. In the present specification, a method for reporting channel state information (CSI), performed by a terminal, comprises the steps of: receiving, from a base station, downlink control information (DCI) indicating activation of a report of semi-persistent (SP) CSI, wherein the downlink control information (DCI) is scrambled using a specific radio network temporary identity (RNTI) distinguished from a cell-radio network temporary identity (C-RNTI); and reporting the semi-persistent (SP) CSI to the base station through a physical uplink shared channel (PUSCH), on the basis of the received downlink control information.
(FR) La présente invention concerne un procédé pour rapporter des CSI dans un système de communication sans fil. Dans la présente invention, un procédé pour rapporter des informations d'état de canal (CSI), réalisé par un terminal, comprend les étapes consistant à : recevoir, en provenance d'une station de base, des informations de commande de liaison descendante (DCI) indiquant l'activation d'un rapport de CSI semi-persistantes (SP), les informations de commande de liaison descendante (DCI) étant brouillées à l'aide d'une identité temporaire de réseau radio (RNTI) spécifique différente d'une identité temporaire de réseau radio cellulaire (C-RNTI)); et rapporter les CSI semi-persistantes (SP) à la station de base par l'intermédiaire d'un canal partagé de liaison montante physique (PUSCH), sur la base des informations de commande de liaison descendante reçues.
(KO) 본 명세서는 무선 통신 시스템에서 CSI를 보고하는 방법을 제공한다. 본 명세서에서, 단말에 의해 수행되는 채널 상태 정보(channel state information, CSI)를 보고(report)하는 방법은, 반-고정적(semi-persistent, SP) CSI 보고의 활성화(activation)를 지시하는 하향링크 제어 정보(downlink control information, DCI)를 기지국으로부터 수신하는 단계, 상기 하향링크 제어 정보는 C-RNTI(Cell-Radio Network Temporary Identity)와 구분되는 특정 RNTI로 스크램블(scramble)되며; 및 상기 수신된 하향링크 제어 정보에 기초하여 물리 상향링크 공유 채널(physical uplink shared channel, PUSCH)를 통해 상기 반-고정적 CSI를 상기 기지국으로 보고하는 단계를 포함하는 것을 특징으로 한다.
