System and method for ue location verification in non-terrestrial network (ntn)

A base station (BS), comprising:

• at least one antenna;
• at least one radio, configured to perform wireless communication using at least one radio access technology;
• and
• one or more processors coupled to the at least one radio, wherein the at least one radio and the one or more processors are configured to cause the BS to:
• acquire, from a satellite in a Non-Terrestrial Network (NTN), an initial measurement between a user equipment (UE) and the satellite for determination of a location of the UE;
• acquire a compensation factor for compensating for a movement of the satellite to be used in determining the location of the UE;
• and
• provide the initial measurement and the compensation factor to a location server for calculation of the location of the UE, wherein satellite ephemeris information and epoch time information at the time of the initial measurement are provided to the location server.

A user equipment (UE), comprising:

• at least one antenna;
• at least one radio, configured to perform wireless communication using at least one radio access technology;
• and
• one or more processors coupled to the at least one radio, wherein the at least one radio and the one or more processors are configured to cause the UE to:
• receive, from a network device in a Non-Terrestrial Network (NTN), a configuration for a multi-round-trip time (multi-RTT) procedure for calculation of a location of the UE, wherein the configuration comprises a parameter which indicates a maximum permissible difference between a time when the UE receives a downlink positioning control signal and a time when the UE sends an uplink positioning control signal during performing the multi-RTT procedure;
• receive the downlink positioning control signal at a first time;
• and
• send the uplink positioning control signal within a time period indicated by the parameter from the first time.
