Abstract

L'invention concerne un procédé de communication de CSI, un terminal, et un dispositif de réseau. L'invention se rapporte au domaine technique des communications, et vise à résoudre le problème lié, dans l'état de la technique, au fait qu'un UE communique les mauvaises CSI car il ne peut pas connaître avec précision le nombre de BWP actuellement activées par le dispositif de réseau. Le procédé consiste à : acquérir des informations d'indication, qui sont utilisées pour commander au terminal de communiquer les CSI correspondant à une première ressource de fréquence d'unité, la première ressource de fréquence d'unité comprenant tout ou partie des ressources de fréquence d'unité activées par le terminal et/ou tout ou partie des ressources de fréquence d'unité désactivées par le terminal, et la ressource de fréquence d'unité comprenant une partie de largeur de bande (BWP) ou une porteuse composante (CC); et communiquer les CSI à un dispositif de réseau d'après les informations d'indication.
