Abstract

La présente divulgation se rapporte à un procédé et à un appareil de détermination d'informations d'état de canal (CSI) et à un support de stockage. Le procédé de détermination d'informations CSI est appliqué à un dispositif côté réseau. Le procédé consiste : à déterminer au moins un ensemble de ressources de mesure d'informations CSI, une plage de fréquences correspondant à l'ensemble de ressources de mesure d'informations CSI étant inférieure ou égale à un premier seuil de largeur de bande, le premier seuil de largeur de bande étant déterminé sur la base d'une largeur de bande de transmission/réception correspondant à la capacité de transmission/réception d'un terminal et l'ensemble de ressources de mesure d'informations CSI étant un ensemble comprenant des ressources de fréquence de signal CSI-RS et/ou des ressources de temps. Selon la présente divulgation, une mesure d'informations CSI peut être réalisée sur une largeur de bande relativement grande du terminal pour déterminer l'état de canal de la largeur de bande entière.
