Abstract

The disclosure relates to drone user equipment (UE) indications that may be conveyed to a wireless network. In particular, a UE that has flight capabilities (i.e., capabilities to operate as an unmanned aircraft system) and optional further capabilities to report a current height level may indicate such capabilities to the wireless network. As such, the wireless network may differentiate the drone UE from other UEs that only operate on the ground. Furthermore, the optional current height level may enable the wireless network to differentiate among drone UEs operating at different heights and/or from other UEs that are operating on the ground. The wireless network may further use the information indicating the flight capabilities either alone or in combination with the optional height information to configure power control parameters, manage interference, provide mobility management functions, generate neighbor lists, control beamforming, or implement a radio resource configuration or management procedure.

First claim

What is claimed is:

1. A method for providing a drone user equipment (UE) indication, comprising:
connecting to a wireless network by a UE having flight capabilities; and
transmitting, by the UE, a drone UE indicator to the wireless network to indicate that the UE is an unmanned aircraft system having the flight capabilities, wherein the drone UE indicator is transmitted to the wireless network as part of a Radio Resource Control (RRC) procedure, during a non-access stratum (NAS) attach procedure, or using Medium Access Control (MAC) signaling during a Random Access Procedure (RACH) when establishing the connection to the wireless network.

2. The method recited in claim 1 , wherein the drone UE indicator is transmitted to the wireless network in response to an event trigger related to one or more of the UE beginning a flight or crossing above a height threshold.

3. The method recited in claim 1 , further comprising indicating, by the UE to the wireless network, a switch to a ground UE mode in response to an event trigger related to one or more of the UE landing or crossing below a height threshold.

4. The method recited in claim 1 , wherein the wireless network is configured to provide the UE an uplink heavy traffic configuration based on the drone UE indicator.

5. The method recited in claim 1 , further comprising:
estimating a distance to a detected base station based on a detected timing difference of a synchronization signal received from the detected base station; and
reporting the estimated distance to the detected base station to the wireless network, wherein the estimated distance to the detected base station is reported relative to a serving base station.

6. The method recited in claim 1 , wherein the UE has height reporting capabilities in addition to the flight capabilities, and wherein the drone UE indicator transmitted to the wireless network further indicates that the UE has the height reporting capabilities.

7. The method recited in claim 6 , further comprising:
determining a current height level associated with the UE; and
reporting the current height level to the wireless network.

8. The method recited in claim 7 , wherein the current height level is reported to the wireless network at one or more of periodic intervals, based on the current height level crossing above or below a particular value, or in combination with other radio resource management measurements that are reported to the wireless network.

9. The method recited in claim 7 , wherein one or more base stations in the wireless network are configured to point one or more directional antenna toward the UE based at least in part on the current height level.

10. An apparatus, comprising:
at least one processor configured to connect to a wireless network; and
a transmitter configured to transmit a drone user equipment (UE) indicator to the wireless network to indicate that the apparatus is an unmanned aircraft system that has flight capabilities, wherein the drone UE indicator is transmitted to the wireless network as part of a Radio Resource Control (RRC) procedure, during a non-access stratum (NAS) attach procedure, or using Medium Access Control (MAC) signaling during a Random Access Procedure (RACH) when connecting to the wireless network.

11. The apparatus recited in claim 10 , wherein the drone UE indicator is transmitted to the wireless network in response to an event trigger related to one or more of the apparatus beginning a flight or crossing above a height threshold.

12. The apparatus recited in claim 10 , wherein the transmitter is further configured to transmit, to the wireless network, information indicating a switch to a ground UE mode in response to an event trigger related to one or more of the apparatus landing or crossing below a height threshold.

13. The apparatus recited in claim 10 , wherein the at least one processor is further configured to estimate a distance to a detected base station based on a detected timing difference of a synchronization signal received from the detected base station and to report, to the wireless network, the estimated distance to the detected base station relative to a serving base station.

14. The apparatus recited in claim 10 , wherein:
the drone UE indicator transmitted to the wireless network further indicates that the apparatus has height reporting capabilities, and
the at least one processor is further configured to determine a current height level associated with the apparatus and report the current height level to the wireless network.

15. The apparatus recited in claim 14 , wherein the current height level is reported to the wireless network at one or more of periodic intervals, based on the current height level crossing above or below a particular value, or in combination with other radio resource management measurements that are reported to the wireless network.

16. The apparatus recited in claim 14 , wherein one or more base stations in the wireless network are configured to point one or more directional antenna toward the apparatus based at least in part on the current height level.

17. An apparatus, comprising:
means for connecting to a wireless network; and
means for transmitting a drone user equipment (UE) indicator to the wireless network to indicate that the apparatus is an unmanned aircraft system that has flight capabilities, wherein the drone UE indicator is transmitted to the wireless network as part of a Radio Resource Control (RRC) procedure, during a non-access stratum (NAS) attach procedure, or using Medium Access Control (MAC) signaling during a Random Access Procedure (RACH) when connecting to the wireless network.

18. The apparatus recited in claim 17 , wherein the drone UE indicator is dynamically configurable such that the drone UE indicator is transmitted to the wireless network in response to an event trigger related to one or more of the apparatus beginning a flight or crossing above a height threshold and information is transmitted to the wireless network to indicate a switch to a ground UE mode in response to an event trigger related to one or more of the apparatus landing or crossing below a height threshold.

19. The apparatus recited in claim 17 , further comprising:
means for estimating a distance to a detected base station based on a detected timing difference of a synchronization signal received from the detected base station; and
means for reporting, to the wireless network, the estimated distance to the detected base station relative to a serving base station.

20. The apparatus recited in claim 17 , wherein the drone UE indicator transmitted to the wireless network further indicates that the apparatus has height reporting capabilities, and wherein the apparatus further comprises:
means for determining a current height level associated with the apparatus; and
means for reporting the current height level to the wireless network at one or more of periodic intervals, based on the current height level crossing above or below a particular value, or in combination with other radio resource management measurements that are reported to the wireless network.

21. The apparatus recited in claim 20 , wherein one or more base stations in the wireless network are configured to point one or more directional antenna toward the apparatus based at least in part on the current height level.

22. A non-transitory computer-readable medium storing computer-executable instructions, the stored computer-executable instructions
