1. A method in a radio access network (RAN) for enabling execution of a dual active protocol stack (DAPS) procedure at a user equipment (UE) communicating with the RAN in dual connectivity (DC) via a master node (MN) of the RAN, the MN covering a primary cell (PCell), and a secondary node (SN) of the RAN, the SN covering a primary secondary cell (PSCell), the method comprising:
causing, by the MN, the UE to release the SN covering the PSCell; and
transmitting, by the MN to the UE, a command to execute the DAPS procedure after the UE releases the SN.
