Abstract

System and techniques for unmanned aerial vehicle navigation are described herein. A plurality of transmission beams may be established. Here, each beam in the plurality of transmission beams is a focused photonic propagation directed to a fixed geographic area and a travel route intersects the fixed geographic areas of the plurality of transmission beams. Cell entry may be received for a vehicle transceiver entering a geographic area for a transmission beam in the plurality of beams. Scrambling codes corresponding to the plurality of transmission beams may be provided to the vehicle. A course parameter, decodable by a scrambling code of the scrambling codes, may be transmitted to the vehicle via the plurality of transmission beams.

Claims

1. A system for unmanned aerial vehicle navigation, the system comprising an eNodeB including:

a transceiver to establish a plurality of transmission beams, each beam in the plurality of transmission beams comprising a focused photonic propagation directed to a fixed geographic area, a travel route intersecting the fixed geographic areas of the plurality of transmission beams;

a decoder to receive cell entry for a vehicle transceiver entering a geographic area for a transmission beam in the plurality of beams; and

an encoder to;

provide scrambling codes corresponding to the plurality of transmission beams to the vehicle, each beam in the plurality of transmission beams having a different scrambling code; and

transmit a course parameter to the vehicle via the plurality of transmission beams.

2. The system of claim 1, wherein the scrambling codes are a single scrambling code that is the same for all beams participating in the route across all cells.

3. The system of claim 1, wherein the course parameter is at least one of a heading, a velocity, or an altitude.

4. The system of claim 1, wherein the course parameter is transmitted via a single beam of the plurality of transmission beams.

5. The system of claim 4, wherein each beam in the plurality of transmission beams includes a corresponding fixed course parameter, a fixed course parameter being the same without regard to a position of the vehicle.

6. The system of claim 5, wherein a second vehicle is sent the same fixed course parameter that is transmitted to the vehicle.

7. The system of claim 5, wherein the fixed course parameter is encoded in a navigation reference signal (NRS), the NRS being different than other NRS for other beams in the plurality of beams.

8. The system of claim 7, wherein the eNodeB is to transition the vehicle into an idle mode after providing the scrambling codes.

9. A method for unmanned aerial vehicle navigation, the method comprising:

establishing a plurality of transmission beams, each beam in the plurality of transmission beams comprising a focused photonic propagation directed to a fixed geographic area, a travel route intersecting the fixed geographic areas of the plurality of transmission beams;
