Abstract
(EN)
The present invention relates to methods and devices for aperiodically reporting channel state information (CSI). According to an embodiment of the present invention, a method for aperiodically reporting channel state information may comprise: a terminal receiving an upper layer signal from a base station, the upper layer signal containing information about at least one allocated CSI measurement group; the terminal receiving a physical downlink control channel (PDCCH) signal via a first subframe from the base station, the PDCCH signal containing a CSI request field; the terminal setting a second subframe as a CSI reference resource based on the first subframe; and determining whether at least one CSI measurement group to which a CSI reference resource is allocated is included.

La présente invention concerne des procédés et des dispositifs pour rapporter de manière apériodique des informations d'état de canal (CSI). Selon un mode de réalisation de la présente invention, un procédé pour rapporter de manière apériodique des informations d'état de canal peut comprendre : la réception, par un terminal, d'un signal de couche supérieure d'une station de base, le signal de couche supérieure contenant des informations concernant au moins un groupe de mesure de CSI attribué; la réception, par le terminal, d'un signal de canal de commande de liaison descendante physique (PDCCH) par l'intermédiaire d'une première sous-trame de la station de base, le signal de PDCCH contenant un champ de demande de CSI; l'établissement, par le terminal, d'une seconde sous-trame en tant que ressource de référence de CSI sur la base de la première sous-trame; et la détermination qu'au moins un groupe de mesure de CSI auquel une ressource de référence de CSI est attribuée est ou non inclus.
