Abstract: A timing advance (TA) value is a time offset that may be applied by a UE to compensate for the propagation delay of the UE and thereby cause the UE's uplink transmissions to be time synchronized with the uplink transmissions of other UEs.

Systems and method are instead disclosed for providing TA values to maintain timing synchronization, e.g. even when the UE is in a power-saving state.
