Title (EN) METHOD FOR TRANSMITTING AND RECEIVING CHANNEL STATE INFORMATION IN MULTI-ANTENNA WIRELESS COMMUNICATION SYSTEM, AND DEVICE THEREFOR
(FR) PROCÉDÉ DESTINÉ À TRANSMETTRE ET À RECEVOIR DES INFORMATIONS D'ÉTAT DE CANAL DANS UN SYSTÈME DE COMMUNICATION SANS FIL MULTI-ANTENNES, ET DISPOSITIF ASSOCIÉ
(KO) 다중 안테나 무선 통신 시스템에서 채널 상태 정보 송수신 방법 및 이를 위한 장치
Abstract: front page image
(EN)According to one aspect of the present invention, a method by which a terminal reports channel state information (CSI) in a multi-antenna wireless communication system can comprise the steps of: receiving first configuration information on a non-precoded first CSI-reference signal (CSI-RS) configuration from a base station; receiving a first CSI-RS; reporting, to the base station, first CSI generated on the basis of the first CSI-RS; and reporting, to the base station, codebook configuration information on a codebook configuration, which becomes the basis for generating the first CSI.
(FR)La présente invention concerne un procédé au moyen duquel un terminal rapporte des informations d'état de canal (CSI) dans un système de communication sans fil muti-antennes qui peut comprendre les étapes consistant : à recevoir les premières informations de configuration sur une configuration de signal de référence des CSI non précodée (CSI-RS) à partir d'une station de base ; à recevoir un premier CSI-RS ; à rapporter, à la station de base, les premières CSI générées sur la base du premier CSI-RS ; et à rapporter, à la station de base, les informations de configuration de livre de codes sur une configuration de livre de codes, qui devient la base destinée à générer les premières CSI.
(KO)본 발명의 일 양상은, 다중 안테나 무선 통신 시스템에서 단말이 채널 상태 정보 (CSI: Channel State Information)를 보고하는 방법에 있어서, 기지국으로부터 프리코딩 되지 않은 (non-precoded) 제 1 채널 상태 정보 -참조 신호 (CSI-RS: CSI -Reference Signal) 구성에 대한 제 1 설정 정보를 수신하는 단계; 상기 제 1 CSI-RS를 수신하는 단계; 상기 제 1 CSI-RS에 기초하여 생성한 상기 제 1 CSI를 상기 기지국으로 보고하는 단계; 및 상기 제 1 CSI를 생성하는 데 기초가 되는 코드북 구성 (configuration)에 관한 코드북 구성 정보를 상기 기지국으로 보고하는 단계; 를 포함할 수 있다.
