Methods and operations by network nodes and user equipments

Abstract:

A UE operating in a RAN may be configured to receive new radio, NR, radio resource control, RRC, messages from a secondary network node. The NR RRC messages may each contain a number that the secondary network node added to the NR RRC messages to indicate their respective order in a sequence which the NR RRC messages were sent by the secondary network node. The NR RRC messages may each contain parameters that the UE uses to configure its communications through a NR interface with the secondary network node. The UE may send NR RRC complete messages toward the secondary network node responsive to receipt of the NR RRC messages, wherein the NR RRC complete messages each contain an indication of the NR RRC message that was received. The UE may control the sending of the NR RRC complete messages to indicate to the secondary network node whether the NR RRC messages are received in an order that is the same as the sequence.
