1. A method, comprising:
obtaining, by a processor of an apparatus, at least one of a downlink (DL) pre-compensated frequency value applied on a service link from a satellite of a non-terrestrial network (NTN) and a feeder link delay drift rate of a feeder link between a network node and the satellite;
obtaining, by the processor, a Doppler frequency shift value; and
performing, by the processor, a timing compensation through adjusting a sampling rate according to at least one of the DL pre-compensated frequency value, the feeder link delay drift rate, and the Doppler frequency shift value.
