Abrégé
(EN)
Provided is a method for operating a terminal for feedback on channel state information (CSI) in a carrier aggregation system according to the present disclosure. The method may comprise the steps of: receiving CSI feedback configuration information for each of a plurality of downlink component carriers from a base station; and feeding channel status information back to the base station through a physical uplink control channel (PUCCH) of an uplink primary component carrier on the basis of the configuration information of the received CSI feedback. The configuration information of the CSI feedback may be received through any one or each of the plurality of downlink component carriers.

L'invention concerne un procédé de fonctionnement d'un terminal utilisé pour le retour d'informations d'état de canal (CSI) dans un système d'agrégation de porteuses. Le procédé peut comprendre les étapes consistant à : recevoir, d'une station de base, des informations de configuration par retour CSI pour chaque porteuse d'une pluralité de porteuses de composantes de liaison descendante; et renvoyer à la station de base des informations d'état de canal par l'intermédiaire d'un canal de commande physique de liaison montante (PUCCH) d'une porteuse de composante primaire de liaison montante en fonction des informations de configuration du retour CSI reçu. Les informations de configuration du retour CSI peuvent être reçues par n'importe quelle porteuse de la pluralité de porteuses de composantes de liaison descendante.

본 명세서에서의 개시에 따르면, 반송파 집성 시스템에서 채널 상태 정보(Channel State Information: CSI) 피드백을 위한 단말의 동작 방법 방법이 제공된다. 상기 동작 방법은 복수의 하향링크 컴포넌트 캐리어 각각에 대한 채널 상태 정보 피드백 구성(CSI feedback configuration) 정보를 기지국으로부터 수신하는 단계와; 상기 수신된 채널 상태 정보 피드백 구성 정보에 기초하여, 상향링크 프라이머리 컴포넌트 캐리어의 물리 상향링크 제어 채널(Physical Uplink Control Channel: PUCCH)을 통해 채널 상태 정보를 상기 기지국으로 피드백하는 단계를 포함할 수 있다. 상기 채널 상태 정보 피드백 구성 정보는 상기 복수의 하향링크 컴포넌트 캐리어 중 어느 하나의 컴포넌트 캐리어를 통해 수신되거나 상기 복수의 하향링크 컴포넌트 캐리어 각각을 통해 수신될 수 있다.
