Classification: CPC H  G | IPC G  H

Claim 15:
16. A method of wireless communication performed by a user equipment, comprising:
estimating a Doppler drift, associated with a service link between the user equipment and a reference point for an uplink transmission, using a position of the user equipment and an ephemeris associated with the reference point, wherein the reference point is one of:
a satellite that provides a cell covering the user equipment, the satellite being associated with a non-terrestrial network, or
a gateway associated with the satellite;

determining a transmission frequency for the uplink transmission using the reference point and a target uplink frequency for signal reception at the reference point,
wherein the determining includes adjusting the transmission frequency to compensate for the estimated Doppler drift, and
wherein the transmission frequency is independent of a received downlink frequency of the user equipment; and

transmitting the uplink transmission using the transmission frequency.
