Abstract
(EN)
A method is performed by a base station of a wireless communication network. The base station is configured as a secondary node for a wireless device having dual- or multi-connectivity to the wireless communication network via a master node and one or more secondary nodes comprising the base station. The method comprises: causing transmission of a message to the master node, the message comprising an indication that the base station is releasing resources associated with one or more layers of a radio connection between the base station and the wireless device.
(FR)
L'invention concerne un procédé mis en œuvre par une station de base d'un réseau de communication sans fil. La station de base est configurée en tant que nœud secondaire pour un dispositif sans fil ayant une connectivité double ou multiple au réseau de communication sans fil par l'intermédiaire d'un nœud maître et d'un ou plusieurs nœuds secondaires comprenant la station de base. Le procédé consiste à : provoquer la transmission d'un message au nœud maître, le message comprenant une indication selon laquelle la station de base libère des ressources associées à une ou plusieurs couches d'une connexion radio entre la station de base et le dispositif sans fil.
