Summary:Various solutions for timing and frequency compensation in non-terrestrial network (NTN) communications are proposed. An apparatus implemented in a user equipment (UE) obtains a carrier frequency of an NTN. The apparatus generates an up-conversion signal by upconverting a baseband signal according to the carrier frequency. Then, the apparatus further obtains a pre-compensation frequency value. The apparatus performs an uplink (UL) frequency pre-compensation through adjusting a phase of the up-conversion signal according to the pre-compensation frequency value.
