Abstract
(EN) The present invention relates to a method for reporting a channel state in a wireless communication system according to one embodiment of the present invention, wherein a terminal can retune between a plurality of narrowbands and receive data, and the method may comprise the steps of: receiving a configuration for reporting a channel state; calculating a channel quality indicator for all the plurality of narrowbands if a periodical broadband feedback mode is configured according to the configuration for reporting a channel state; and reporting the calculated channel quality indicator.
(FR) La présente invention porte sur un procédé de déclaration d’état de canal dans un système de communication sans fil selon un mode de réalisation de la présente invention, un terminal pouvant s’accorder en alternance entre une pluralité de bandes étroites et recevoir des données, et les étapes du procédé pouvant consister : à recevoir une configuration de déclaration d’un état de canal ; à calculer un indicateur de qualité de canal pour l’ensemble de la pluralité de bandes étroites si un mode de rétroaction de bande large est configuré en fonction de la configuration de déclaration d’état de canal ; et à déclarer l’indicateur de qualité de canal calculé.
(KO) 본 발명의 일 실시예에 따른 무선 통신 시스템에서 채널 상태 보고를 위한 방법에 관한 것으로서, 상기 단말은 복수의 협대역 사이를 재조정(retuning)해가며 데이터를 수신할 수 있고, 상기 방법은 채널 상태 보고를 위한 설정을 수신하는 단계, 상기 채널 상태 보고를 위한 설정에 따라 주기적 광대역 피드백 모드가 설정되면, 상기 복수의 협대역 전부를 위한 채널 품질 지시자를 계산하는 단계, 및 상기 계산된 채널 품질 지시자를 보고하는 단계를 포함할 수 있다.
