Title (EN) METHOD AND APPARATUS FOR PERFORMING CSI REPORTING ON BASIS OF SUBBAND GROUP
(FR) PROCÉDÉ ET APPAREIL POUR ÉTABLISSEMENT DE RAPPORT CSI DE GROUPE DE SOUS-BANDE
(KO) 서브밴드 그룹에 기초하여 CSI 리포팅을 수행하는 방법 및 이를 위한 장치
Abstract:
(EN) The present specification relates to a method for reporting CSI in a wireless communication system, which is performed by a terminal, the method comprising the steps of: receiving information on CSI reporting timing from a base station; receiving, from the base station, first control information, which is information on a frequency region to be subject to subband reporting, and second control information, which is information on a maximum number of subbands to be subject to subband reporting; receiving, from the base station, information on a subband starting position for setting a subband group; setting an interval between subbands on the basis of the first control information and the second control information; setting a subband group on the basis of the starting position and the interval between the subbands; and performing CSI reporting of the set subband group, wherein the subband group is a subband to be subject to CSI reporting in the subbands.
(FR) La présente invention concerne un procédé d'établissement de rapport CSI dans un système de communication sans fil, au moyen d'un terminal, le procédé comprenant les étapes consistant à : recevoir des informations concernant une temporisation d'établissement de rapport CSI à partir d'une station de base; recevoir, en provenance de la station de base, des premières informations de commande, qui sont des informations sur une zone de fréquence à soumettre à un établissement de rapport de sous-bande, et des secondes informations de commande, qui sont des informations sur un nombre maximal de sous-bandes à soumettre à un établissement de rapport de sous-bande; recevoir, en provenance de la station de base, des informations sur une position de départ de sous-bande pour définir un groupe de sous-bandes; définir un intervalle entre les sous-bandes sur la base des premières informations de commande et des secondes informations de commande; définir un groupe de sous-bandes sur la base de la position de départ et de l'intervalle entre les sous-bandes; et effectuer un établissement de rapport CSI du groupe de sous-bandes défini, le groupe de sous-bandes étant une sous-bande à soumettre à un établissement de rapport CSI dans les sous-bandes.
(KO) 본 명세서는 무선 통신 시스템에서 CSI 보고 (CSI reporting)를 하는 방법에 있어서, 단말에 의해 수행되는 방법은, CSI reporting timing에 대한 정보를 기지국으로부터 수신하는 단계; 서브밴드 리포팅 (subband reporting)의 대상이 되는 주파수 영역(frequency region)에 대한 정보인 제1 제어정보 및 subband reporting을 수행할 subband 최대 개수에 대한 정보인 제2 제어정보를 기지국으로부터 수신하는 단계; subband group을 설정하기 위한 subband 시작 위치에 대한 정보를 기지국으로부터 수신하는 단계; 제1 제어정보 및 제2 제어정보에 기초하여 subband 사이 간격을 설정하는 단계; 상기 시작 위치 및 상기 subband 사이 간격에 기초하여 subband group을 설정하는 단계; 상기 설정된 subband group에 대한 CSI reporting을 수행하는 단계; 를 포함하고, 상기 subband group은 subband 내에서 CSI reporting을 수행할 subband 인 것을 특징으로 한다.
