Classification: CPC H  G | IPC G  H

Claim 26:
27. An apparatus for wireless communication, comprising:
means for estimating a Doppler drift, associated with a service link between the apparatus and a reference point for an uplink transmission, using a position of the apparatus and an ephemeris associated with the reference point, wherein the reference point is one of:
a satellite that provides a cell covering the apparatus, the satellite being associated with a non-terrestrial network, or
a gateway associated with the satellite;

means for 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 apparatus; and

means for transmitting the uplink transmission using the transmission frequency.
