Beschreibung
Zusammenfassung:	A device of a user equipment (LTE) includes at least one transceiver and at least one processor coupled to the at least one transceiver. The at least one processor is configured to perform a compensation for doppler shift based on ephemeris information for non-terrestrial network (NTN) device and position information of the UE. The at least one processor is configured to transmit a message including compensation information to a network node through the NTN device based on the compensation. The compensation information indicates at least one of a frequency shift value according to the doppler shift or a doppler shift change rate indicating a change rate of a frequency shift value per unit time. The NTN device includes a satellite that moves based on the ephemeris information.
