Abstract: Improved techniques of handover include the source gNB estimating the accuracy of the timing information that the UE may derive from its local clock during and shortly after the HO procedure and exchange this with the target gNB. Based on this estimate. the target gNB can determine when a timing information update is needed at the UE.

Abstract: Systems, methods, apparatuses, and computer program products for working clock determination for a mobile user equipment. A method may include receiving time domain information at a session management function during a protocol data unit (PDU) session procedure. The method may also include forwarding the time domain information to a user plane function for the PDU session procedure. The method may further include configuring the user plane function according to the time domain information to enable determination of a correct mapping between the time domain information and a user equipment or a PDU session.
