(FR) APPAREILS ET PROCÉDÉS DESTINÉS À UNE DOUBLE CONNECTIVITÉ
Abstract
(EN)
The present disclosure relates to radio network communication. In one of its aspects, the disclosure presented herein concerns a method for handling dual connectivity (DC) in a wireless communication system. The method is implemented in a first Base Station (BS). The wireless communication system is adapted to provide for DC between a wireless device and the first BS and between the wireless device and a second BS. According to the method, a request to allocate resources for DC operation for the wireless device is transmitted to the second BS. The request comprises an identifier that identifies a wireless device model of the wireless device.

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.
