Abstract (en)

[origin: WO2023011852A1] There is provided an apparatus, a method, a computer program, a non-transitory computer readable medium, a user equipment, a source node, a target node, a network, and a system. In at least some examples, reconfiguration information is sent for execution by a user equipment. The reconfiguration information comprises dual active protocol stack, DAPS, handover information. The DAPS handover information includes secondary cell release information to enable initiation of secondary cell release from a source protocol stack at a defined trigger point during execution of a DAPS handover based on reception of the DAPS handover information at the user equipment.
