Abstract

L'invention concerne un dispositif et un procédé d'exécution d'une planification semi-persistante d'une partie de largeur de bande (BWP) permettant de contrôler des processus liés à une SPS dans un mécanisme prenant en charge une pluralité de BWP pour un UE. Le dispositif et le procédé permettent la commande d'un changement d'une BWP activée tout en envoyant un message d'activation ou de libération de SPS à un équipement d'utilisateur, ou permettent une utilisation appropriée de ressources de SPS lorsqu'une BWP activée est remplacée par une BWP d'origine après un changement de la BWP activée dans un état activé par SPS, ou permettent une commande appropriée d'un temporisateur d'une BWP lorsqu'une SPS est activée ou libérée, ou permettent un changement d'une BWP activée selon un cycle SPS, fournissant ainsi un mécanisme de déclenchement innovant de changement de BWP activées.
