Abstract

Embodiments include methods, performed by a master node (MN) in a radio access network, for establishing radio resources between a secondary node (SN) and a user equipment (UE). Such embodiments include sending, to the SN, a request identifying one or more QoS flows to be setup between the SN and the UE; and receiving, from the SN, a response including identification of one or more radio bearers that were admitted by the SN in association with the requested QoS flows. Such embodiments also include sending, to the SN, identifiers of one or more tunnels for forwarding downlink user-plane (DL UP)data over an interface between the SN and the MN. Each tunnel identifier is associated with a respective admitted radio bearer. Embodiments also include complementary methods performed by a SN, as well as network nodes configured to perform the various methods.

Description

technical field [0001] The present application relates generally to the field of wireless communication networks, and more particularly to devices, methods and computer-readable media that facilitate simultaneous connection of a device or user equipment (UE) to multiple nodes in a radio access network (RAN). Background technique [0002] Generally, all terms used herein will be interpreted according to their ordinary meanings in the relevant technical field, unless a different meaning is clearly given and / or implied from the context in which the terms are used. Unless expressly stated otherwise, all references to "a / an / element, device, component, means, step, etc." should be construed openly as referring to at least one instance of the element, device, component, means, step, etc. . The steps of any method disclosed herein do not have to be performed in the exact order disclosed, unless one step has to be explicitly described as being after or before another step and / or imp...
