Abstract

Determining a location of a user equipment includes transmitting, by one or more processors from a network node, a first beam having a first frequency range in a first area and a second beam having a second frequency range in a second area. The first area is larger than and encompasses the second area. A request for determining the location of the user equipment is received. The one or more processors may then cause the second beam to sweep within the first area, receive a second signal from the user equipment indicating when the second beam is swept over the location of the user equipment and data related to signal measurements of the second beam at the user equipment, and determine the location of the user equipment based on a pointing direction of the second beam relative to a position of the node of the network and the received data.

Claims (47)

1. A method of determining a location of a user equipment, the method comprising:

transmitting, by one or more processors from a node of a network, a first beam having a first frequency range in a first area and a second beam having a second frequency range in a second area, the first area being larger than the second area and encompassing the second area;

receiving, by the one or more processors, a request for determining the location of the user equipment in a first signal that is in the first frequency range;

causing, by the one or more processors, the second beam to sweep within the first area;

receiving, by the one or more processors, a second signal from the user equipment indicating when the second beam is swept over the location of the user equipment and data related to signal measurements of the second beam at the user equipment; and

determining the location of the user equipment based on a pointing direction of the second beam relative to a position of the node of the network and the data related to the signal measurements.

2. The method of claim 1 , wherein the first frequency range is within a range of 4G Long-Term Evolution (LTE) communication signals, and the second frequency range is within a range of 5G New Radio (NR) communication signals.

3. The method of claim 1 , wherein transmitting the second beam occurs after the receiving of the request.

4. The method of claim 1 , wherein the request includes an indication of a capability of the user equipment to detect the first frequency range and the second frequency range.

5. The method of claim 1 , wherein the causing of the second beam to sweep within the first area includes physically adjusting a pointing direction of the second beam.

6. The method of claim 1 , wherein the causing of the second beam to sweep within the first area includes electronically adjusting a pointing direction of the second beam using beamforming techniques.

7. The method of claim 1 , wherein the causing of the second beam to sweep includes causing the second beam to sweep in a set pattern.

8. The method of claim 1 , wherein the causing of the second beam to sweep within the first area until the location of the user equipment is determined.

9. The method of claim 1 , further comprising:

transmitting a third beam having a third frequency range in a third area, the third area being smaller than the first area and being encompassed by the first area;

causing the third beam to sweep within the first area; and

receiving a third signal from the user equipment indicating when the third beam is swept over the location of the user equipment and second data related to second signal measurements of the third beam at the user equipment; and

wherein the determining of the location of the user equipment is further based on a pointing direction of the third beam and the second data related to the second signal measurements.

10. A system for determining a location of a user equipment, the system comprising:

one or more transceivers configured to transmit and receive communication beams comprising one or more signals, the communication beams including a first beam having a first frequency range and a second beam having a second frequency range; and

one or more processors configured to:

transmit, using the one or more transceivers, the first beam in a first area and the second beam in a second area, the first area being larger than the second area and encompassing the second area;

receive, via the one or more transceivers, a request for determining the location of the user equipment in a first signal that is in the first frequency range;

cause the second beam to sweep within the first area;

receive, via the one or more transceivers, a second signal from the user equipment indicating when the second beam is swept over the location of the user equipment and data related to signal measurements of the second beam at the user equipment; and

determine the location of the user equipment based on a pointing direction of the second beam relative to a position of the system and the data related to the signal measurements.

11. The system of claim 10 , wherein the first frequency range is within a range of 4G Long-Term Evolution (LTE) communication signals, and the second frequency range is within a range of 5G New Radio (NR) communication signals.

12. The system of claim 10 , wherein the one or more processors are configured to transmit the second beam after receiving the request.

13. The system of claim 10 , wherein the request includes an indication of a capability of the user equipment to detect the first frequency range and the second frequency range.

14. The system of claim 10 , further comprising a gimbal; and

wherein the one or more processors are configured to cause the second beam to sweep using the gimbal to physically adjust a pointing direction of the second beam.

15. The system of claim 10 , wherein the one or more processors are configured to cause the second beam to sweep within the first area using beamforming techniques.

16. The system of claim 10 , wherein the one or more processors are configured to cause the second beam to sweep in a set pattern.

17. The system of claim 10 , wherein the one or more processors are configured to cause the second beam to sweep within the first area until the location of the user equipment is determined.

18. The system of claim 10 , wherein the one or more transceivers are further configured to transmit and receive a third beam having a third frequency range; and

wherein the one or more processors are further configured to:

transmit the third beam in a third area, the third area being smaller than the first area and being encompassed by the first area;

cause the third beam to sweep within the first area;

receive a third signal from the user equipment indicating when the third beam is swept over the location of the user equipment and second data related to second signal measurements of the third beam at the user equipment; and

determine the location of the user equipment further based on a pointing direction of the third beam and the second data related to the second signal measurements.

19. The system of claim 10 , further comprising a high-altitude platform terminal.

20. A non-transitory, computer-readable medium including instructions that, when executed by one or more processors, cause the one or more processors to perform a method of determining a location of a user equipment, the method comprising:

transmitting a first beam having a first frequency range in a first area and a second beam having a second frequency range in a second area, the first area being larger than the second area and encompassing the second area;

receiving a request for determining the location of the user equipment in a first signal that is in the first frequency range;

causing the second beam to sweep within the first area;

receiving a second signal from the user equipment indicating when the second beam is swept over the location of the user equipment and data related to signal measurements of the second beam at the user equipment; and

determining the location of the user equipment based on a pointing direction of the second beam and the data related to the signal measurements.
