Section: 5.7.19 Satellite switch with re-synchronization in RRC_CONNECTED
Content: The UE shall: 1> stop timer T430 if running; 1> inform lower layers that UL synchronisation is lost due to satellite switch with re-synchronization; 1> start re-synchronising to the DL of the SpCell served by the satellite indicated by ntn-Config in SatSwitchWithReSync; 1> start timer T430 with the timer value set to ntn-UlSyncValidityDuration from the subframe indicated by epochTime in ntn-Config in SatSwitchWithReSync; 1> inform lower layers when UL synchronisation is obtained. Editor's Note: FFS whether in the soft-switch scenario a UE can obtain DL synchronization from the target satellite without losing UL synchronization to the source satellite.
