Abstract

La présente invention se rapporte à une communication de réseau radioélectrique. Selon un de ses aspects, la présente invention concerne un procédé permettant de gérer une double connectivité (DC) dans un système de communication sans fil. Le procédé est mis en œuvre dans une première station de base (BS). Le système de communication sans fil est configuré pour fournir un courant continu entre un dispositif sans fil et la première BS et entre le dispositif sans fil et une seconde BS. Selon le procédé, une demande d'attribution de ressources pour une opération en courant continu destinée au dispositif sans fil est transmise à la seconde BS. La demande comprend un identifiant qui identifie un modèle de dispositif sans fil du dispositif sans fil.
