    Publication number: 20250106720
    Abstract: A communication device of a communications network can perform a dual active protocol stack (“DAPS”) handover (“HO”) from a source cell associated with a first network node of the communications network to a target cell associated with a second network node of the communications network. Performing the DAPS HO can include performing a first random access (“RA”) procedure with the source cell and performing a second RA procedure with the target cell. The communication device can determine RA content to include in a report associated with the DAPS HO. The communication device can transmit the report to a third network node of the communications network toward a target cell.
