Abstract
A user equipment (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: estimate a first Doppler frequency shift in a signal received from a non-terrestrial network (NTN) node at a first time instance, estimate a second Doppler frequency shift in the signal at a second time instance, estimate a signal propagation delay between the NTN node and the UE based on the first Doppler frequency shift and the second Doppler frequency shift, and apply the signal propagation delay to compensate for an uplink transmission from the UE to the NTN node.
