Such embodiments include initiating a first radio resource control, RRC, entity to communicate with the UE via a first DU. Such embodiments also include selecting a second DU to communicate with the UE in a dual-connectivity, DC, configuration with the first DU. Such embodiments also include, based on whether the selected second DU is associated with the first CU, determining whether to initiate a second RRC entity, within the first CU, to communicate with the UE via the second DU. Other embodiments include complementary methods and/or procedures performed by UEs; CUs and UEs configured to perform such methods and/or procedures; and computer-readable media storing instructions corresponding to such methods and/or procedures.
