Abstract:
Embodiments of the present disclosure relate to devices, methods, apparatuses, and computer readable storage media of enhanced UL synchronization for improved system performance. The method comprises obtaining a configuration of a gap within which a radio resource control connected state of the first device is kept; receiving, within the gap, system broadcasted information used for deriving a compensation associated with a transmission between the first device and a second device; and performing a uplink synchronization between the first device to the second device within the gap. In this way, a process of the GNSS fix position refreshing and/or satellite ephemeris data reception and UL/DL re-synchronization can be achieved by the UE in RRC connected mode and therefore the resources and power consumption can be reduced.
