Title:

METHODS AND APPARATUSES FOR GNSS OUTAGE SIGNALING

Document Type and Number:

WIPO Patent Application WO/2022/154089

Kind Code:

A1

Abstract:

A user equipment (UE), having Global Navigation Satellite System (GNSS) capabilities and capable of estimating a signal propagation delay between a non-terrestrial network (NTN) node and the UE based on Doppler frequency shift, is disclosed. The UE includes one or more non-transitory computer-readable media having computer-executable instructions embodied thereon, and at least one processor coupled to the one or more non-transitory computer-readable media, and configured to execute the computer-executable instructions to: transmit a GNSSOutageUE indication of a GNSS outage of the UE to a ground-based base station communicatively coupled to the NTN node; wherein the GNSSOutageUE indication is transmitted in at least one of: uplink control information (UCI); a periodic Channel State Information (CSI) report with CSI information; a Medium Access Control (MAC) Control Element (CE); and a Physical Uplink Control Channel (PUCCH).
