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

Abstract:
(EN) The present specification provides a transmission and reception method for reporting channel state information (CSI) in a wireless communication system, and an apparatus therefor. Particularly, the method for reporting the CSI in the wireless communication system comprises the steps of: receiving, from a base station, configuration information for control channel-based CSI reporting; receiving, from the base station, downlink control information including information for indicating a CSI reporting time at which the control channel-based CSI reporting is performed; and reporting the CSI, which is measured by a CSI-reference signal (CSI-RS) received from the base station, through the control channel at the CSI reporting time, wherein the configuration information can include information for indicating one or more control channel resources allocated for the control channel-based CSI reporting.
(FR) La présente invention concerne un procédé de transmission et de réception servant à signaler des informations d'état de canal (CSI) dans un système de communication sans fil et un appareil correspondant. En particulier, le procédé servant à signaler les CSI dans le système de communication sans fil comprend les étapes consistant à : recevoir, en provenance d'une station de base, des informations de configuration pour signaler des CSI sur la base d'un canal de commande ; recevoir, en provenance de la station de base, des informations de commande en liaison descendante comprenant des informations pour indiquer un moment de signalisation de CSI auquel est effectuée la signalisation de CSI basée sur un canal de commande ; et signaler les CSI, qui sont mesurées par un signal de référence de CSI (CSI-RS) reçu en provenance de la station de base, par l'intermédiaire du canal de commande au moment de la signalisation de CSI, les informations de configuration pouvant comprendre des informations pour indiquer une ou plusieurs ressources de canal de commande attribuées pour la signalisation de CSI basée sur un canal de commande.
(KO) 본 명세서는 무선 통신 시스템에서 채널 상태 정보를 보고하는 송수신하는 방법 및 이를 위한 장치를 제공한다. 구체적으로, 무선 통신 시스템에서 채널 상태 정보(Channel State Information, CSI)를 보고하는 방법은, 기지국으로부터, 제어 채널(control channel) 기반의 CSI 보고를 위한 설정 정보를 수신하는 단계; 상기 기지국으로부터, 상기 제어 채널 기반의 CSI 보고를 수행할 CSI 보고 시점(timing)을 나타내는 정보를 포함하는 하향링크 제어 정보를 수신하는 단계; 및 상기 기지국으로부터 수신한 채널 상태 정보 참조 신호(CSI-Reference Signal, CSI-RS)에 의해 측정된 CSI를, 상기 CSI 보고 시점에 제어 채널을 통해 보고하는 단계를 포함하되, 상기 설정 정보는, 제어 채널 기반의 CSI 보고를 위해 할당된 하나 이상의 제어 채널 자원(control channel resource)들을 나타내는 정보를 포함할 수 있다.
