  • Publication number: 20240107489
    Abstract: Disclosed are techniques for location verification. In an aspect, a radio access network (RAN) node receives a request from a core network node to verify a location of a user equipment (UE), performs a RAN-based positioning procedure with the UE to determine a verified location of the UE, and transmits a response to the core network node, the response including: measurements obtained by the UE during the RAN-based positioning procedure, measurements obtained by the RAN node during the RAN-based positioning procedure, the verified location of the UE, an indication that the location of the UE is verified, or any combination thereof.

  • Publication number: 20230336212
    Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus at a UE in NTN are provided. The UE may be configured to receive one or more FPC commands from an NTN. The UE may be further configured to transmit, in response to receiving the one or more FPC commands, an uplink transmission with a frequency change having a total FPC adjustment calculated based on (a) a current UE location update and a current UE velocity update, wherein the total FPC adjustment satisfies one or more threshold requirements, or (b) an intermediary UE location update between the current UE location update and a previous UE location update and an intermediary UE velocity update between the current UE velocity update and a previous UE velocity update.
