Abstract:
A master node (1) requests a conditional PSCell addition (CPA), via an SN ADDITION REQUEST message (301), to a candidate secondary node (2). The master node (1) also requests the candidate secondary node (2) to configure an SN terminated MCG bearer via the SN ADDITION REQUEST message (301). This can, for example, contribute to mitigating a communication continuity problem caused by a Conditional PSCell Addition (CPA) failure.
