Abstract: front page image
(EN) The present specification provides a method for measuring and reporting channel state information in a wireless communication system. Specifically, a method by which a terminal reports channel state information (CSI) in a wireless communication system includes: a process for receiving CSI configuration information related to a CSI report procedure; a process for receiving one or more CSI-reference signals (CSI-RSs); and a process for reporting the CSI determined as a measurement value estimated from the one or more CSI-RSs, wherein first triggering for transmission of the one or more CSI-RSs and second triggering for the CSI report can be instructed through downlink control information.
(FR) La présente invention concerne un procédé de mesure et de rapport d'informations d'état de canal dans un système de communication sans fil. Plus particulièrement, un procédé par lequel un terminal rapporte des informations d'état de canal (CSI) dans un système de communication sans fil comprenant : un processus de réception d'informations de configuration de CSI relatives à une procédure de rapport de CSI ; un processus de réception d'au moins un signal de référence de CSI (CSI-RS) ; et un processus de rapport des CSI déterminées en tant que valeur de mesure estimée à partir desdites CSI-RS, le premier déclenchement de transmission desdites CSI-RS et un second déclenchement de rapport de CSI pouvant être ordonné par l'intermédiaire d'informations de commande de liaison descendante.
(KO) 본 명세서는 무선 통신 시스템에서 채널 상태 정보를 측정 및 보고하는 방법을 제공한다. 구체적으로, 무선 통신 시스템에서 단말이 채널 상태 정보(Channel State Information, CSI)를 보고하는 방법은, CSI 보고 절차와 관련된 CSI 설정 정보(CSI configuration information)를 수신하는 과정과, 하나 이상의 채널 상태 정보 참조 신호(CSI-Reference Signal, CSI-RS)들을 수신하는 과정과, 상기 하나 이상의 CSI-RS들에 의해 추정된 측정 값으로 결정된 상기 CSI를 보고하는 과정을 포함하며, 상기 하나 이상의 CSI-RS들의 전송에 대한 제1 트리거링(triggering) 및 상기 CSI의 보고에 대한 제2 트리거링은, 하향링크 제어 정보(downlink control information)를 통해 지시될 수 있다.
