Abstract

Les modes de réalisation de la présente invention proposent un procédé de commande de puissance, qui est exécuté par un équipement utilisateur (UE). Le procédé consiste à : déterminer si des informations d'indication sont reçues en provenance d'une station de base ; déterminer un ensemble de paramètres de commande de puissance pour transmettre des données avec une première priorité selon que les informations d'indication ont été reçues ou non ; et commander une puissance de transmission d'un canal pour transmettre les données avec la première priorité sur la base de l'ensemble déterminé de paramètres de commande de puissance. Les modes de réalisation de l'invention concernent en outre un dispositif correspondant et un support de stockage informatique correspondant.
