Flight path reporting format for unmanned aerial vehicles
Exchange of flight path information between a mobile network and an unmanned aerial vehicle (UAV) assumes a particular format for the flight path information, usually a waypoint format. However, there are many circumstances in which the mobile network may prefer flight path information in other formats, such as polygon formats (also referred to as “flight volume formats”). Techniques and apparatuses described herein provide greater flexibility with respect to formatting requests for flight path information and encoding responses to such requests. For example, a base station may transmit a request for flight path information with a format indicator that informs a UAV of a desired format for the requested flight path information. The UAV may then provide the flight path information according to the format indicator.

14. The method of claim 8 , wherein the flight path information is received in a flight path information report.
15. The method of claim 8 , wherein the flight path information indicates at least one of:
respective times that the UE is expected to arrive at waypoints of a set of waypoints indicated in the flight path information if the flight path format is the waypoint flight path format, or
respective times that the UE is expected to occupy polygons of the set of multiple polygons if the format is the volume flight path format.
16. The method of claim 15 , wherein the respective times that the UE is expected to occupy the polygons of the set of multiple polygons include at least one of:
respective times that the UE is expected to enter the polygons,
respective times that the UE is expected to exit the polygons,
respective durations of time that the UE is expected to occupy the polygons, or
a combination thereof.
17. A method of wireless communication performed by a network device, comprising:
receiving information that identifies a user equipment (UE) and a flight path format of a plurality of flight path formats configured for flight path information that is reported by the UE to a base station,
wherein the plurality of flight path formats include at least a waypoint flight path format and a volume flight path format that indicates a set of multiple polygons the UE is expected to occupy; and
transmitting, to the base station, a format indicator that identifies the flight path format and a UE identifier that identifies the UE.
18. The method of claim 17 , wherein the information that identifies the UE and the flight path format are received based at least in part on authorization of a flight plan of the UE.
19. The method of claim 17 , wherein the format indicator and the UE identifier are transmitted to the base station based at least in part on authorization of a flight plan of the UE.
20. The method of claim 17 , wherein the information that identifies the UE and the flight path format are received from an unmanned aircraft systems service supplier (USS) device or from a core network device that communicates with the USS device.
21. The method of claim 20 , wherein the information that identifies the UE and the flight path format are received from the USS device via a service capability exposure function (SCEF) application programming interface (API) or a network exposure function (NEF) API.
