Title
(DE) VERFAHREN ZUR MELDUNG DES KANALSTATUS UND VORRICHTUNG DAFÜR
(EN) METHOD FOR REPORTING CHANNEL STATE AND APPARATUS THEREFOR
(FR) PROCÉDÉ DE DÉCLARATION D'ÉTAT DE CANAL ET APPAREIL ASSOCIÉ
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.
