Google patents method for phones to sync with satellite signals

This patent describes how a mobile device can stay synchronized with a satellite network. The device receives a schedule and timing adjustments to account for the movement between the satellite and the phone.

Why it mattersIt helps ensure reliable connections as satellite internet becomes more common for mobile users.

In the filing’s own words

A UE receives, from a non-terrestrial network (NTN), a measurement configuration that indicates (i) a timing pattern according to which a signal source associated with the NTN transmits a synchronization signal and (ii) a timing parameter related to a change in timing alignment between the UE and the signal source. The UE receives, from the signal source, the synchronization signal in accordance with the timing pattern and the timing parameter.

What exactly they claim (claim 1)

1. A method for synchronization signal measurement implemented in a user equipment (UE), the method comprising: receiving, by the UE from a non-terrestrial network (NTN), a measurement configuration that indicates (i) a timing pattern according to which a signal source associated with the NTN transmits a synchronization signal and (ii) a timing parameter related to a change in timing alignment between the UE and the signal source; and receiving, by the UE from the signal source, the synchronization signal at a synchronization signal reception time based on the timing pattern and a time shift depending on (a) the timing parameter, and (b) a time that elapsed since the receiving of the measurement configuration.
