Abstract
(EN) To solve the above-mentioned problem, a method in which a terminal reports channel state information comprises the following steps: receiving, from a base station, information on a plurality of patterns to be used in a channel state measurement; receiving, from the base station, selection information for selecting a pattern from among the plurality of patterns that is to be used in the channel state information to be reported to the base station; measuring a channel state using the information on the plurality of patterns; and selecting a portion of the measured channel state based on the selection information, and reporting the selected portion to the base station. The above-described solution enables the efficient reporting of channel state information including CQI/CSI, thus improving communication efficiency.
(FR) La présente invention concerne un procédé dans lequel un terminal rapporte des informations d'état de canal. Ledit procédé comprend les étapes suivantes qui consistent : à recevoir, à partir d'une station de base, des informations concernant une pluralité de motifs destinés à être utilisés dans une mesure d'état de canal; à recevoir, à partir de la station de base, des informations de sélection pour sélectionner un motif, parmi la pluralité de motifs, qui doit être utilisé dans les informations d'état de canal à rapporter à la station de base; à mesurer un état de canal en utilisant les informations concernant la pluralité de motifs; et à sélectionner une partie de l'état mesuré de canal en fonction des informations de sélection, et à rapporter la partie sélectionnée à la station de base. La solution décrite ci-dessus permet de rapporter efficacement des informations d'état de canal qui comprennent CQI/CSI, améliorant ainsi l'efficacité de communication.
