FULL RRC CONFIGURATION IN EN-DC

Abstract:

Methods, systems and network devices for operating a network node to provide dual connectivity in a handover of a user equipment, UE, in a new radio telecommunications system are provided. Methods include sending, from the network node and to a target secondary node, an addition request message to allocate resources for the UE in the handover. Operations include receiving an addition request acknowledgement message from the target secondary node. The addition request acknowledgement message includes a context indication regarding a full radio resource control, RRC, context or a delta RRC context. The delta RRC context includes data that is updated relative to data in a current UE context. Operations include determining, based on context indication, a type of RRC context to provide to the target secondary node.
