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

Abstract: front page image
(EN)Disclosed are a method for transmitting and receiving channel state information in a wireless communication system and an apparatus therefor. Specifically, a method for transmitting, by a terminal, channel state information (CSI) in a wireless communication system comprises the steps of: receiving a CSI process setting from a base station; and reporting, to the base station, CSI corresponding to a CSI process set by the CSI process setting, wherein when the CSI process is set to a beamformed CSI-reference signal (CSI-RS) type, and the CSI process is associated with a single CSI-RS resource, a codebook used for deriving the CSI may be indicated by the CSI process setting.
(FR)L'invention concerne un procédé de transmission et de réception d'informations d’état de canal dans un système de communications sans fil, et un appareil associé. Plus précisément, un procédé de transmission d’informations d'état de canal (CSI) par un terminal dans un système de communications sans fil comprend les étapes consistant à : recevoir une définition de processus de CSI, d'une station de base ; et rapporter à la station de base des CSI correspondant à un processus de CSI défini par la définition de processus de CSI. Lorsque le processus de CSI est défini à un type de signal de référence de CSI (CSI-RS) en forme de faisceau et que le processus de CSI est associé à une ressource CSI-RS unique, un livre de codes utilisé pour dériver les CSI peut être indiqué par la définition de processus de CSI.
(KO)무선 통신 시스템에서 채널 상태 정보 송수신 방법 및 이를 위한 장치가 개시된다. 구체적으로, 무선 통신 시스템에서 단말이 채널 상태 정보 (CSI: Channel State Information)를 전송하는 방법에 있어서, 기지국으로부터 CSI 프로세스 설정을 수신하는 단계 및 상기 CSI 프로세스 설정에 의해 설정된 CSI 프로세스에 대응되는 CSI를 상기 기지국에게 보고하는 단계를 포함하고, 상기 CSI 프로세스가 빔포밍된 (beamformed) CSI - 참조 신호 (CSI-RS: CSI-Reference Signal) 타입으로 설정되고, 상기 CSI 프로세스가 단일의 CSI-RS 자원과 연관된 경우, 상기 CSI 프로세스 설정에 의해 상기 CSI 도출을 위하여 이용되는 코드북이 지시될 수 있다.
