Abstract

A device includes a transceiver, a receiver, and a processor. The transceiver is configured to receive feedback data from an unmanned aerial vehicle (UAV) and transmit control data to the UAV via a first communication link. The receiver is configured to receive the control data from a controlling terminal via a second communication link. The second communication link does not interfere with the first communication link. The processor is configured to determine whether the feedback data and the control data are being simultaneously transmitted via the first communication link.

First claim

What is claimed is:

1. A device comprising:
a transceiver configured to receive feedback data from an unmanned aerial vehicle (UAV) and transmit control data to the UAV via a first communication link;
a receiver configured to receive the control data from a controlling terminal via a second communication link, wherein the second communication link does not interfere with the first communication link; and
a processor configured to determine whether the feedback data and the control data are being simultaneously transmitted via the first communication link.

2. The device of claim 1 , wherein:
the feedback data includes a feedback indicator indicating whether a transmission of the feedback data via the first communication link is ongoing or will start soon; and
the control data includes a control data indicator indicating whether a transmission of the control data via the first communication link is ongoing or will start soon.

3. The device of claim 1 , wherein the processor is further configured to terminate a transmission of the control data via the first communication link by shutting down or disabling the receiver when the feedback data and the control data are being simultaneously transmitted via the first communication link.

4. The device of claim 3 , wherein the termination of the transmission of the control data via the first communication link is further determined based on one or more communication conditions, wherein the one or more communication conditions include at least one of an interference level, a signal-to-noise ratio, or an error rate.

5. The device of claim 1 , wherein the processor is further configured to modify the control data based on the feedback data before transmitting the control data to the UAV.

6. The device of claim 1 , wherein the feedback data includes sensor data or status data indicating an operational state, a speed, a position, or an attitude of the UAV.

7. The device of claim 1 , wherein the first communication link or the second communication link is a wireless communication link or a wired communication link.

8. The device of claim 1 , wherein the feedback data and the control data are transmitted via the first communication link using a frequency division multiplexing (FDM) scheme or a time division multiplexing (TDM) scheme to reduce interference.

9. The device of claim 8 , wherein the feedback data is transmitted from the UAV at a first frequency band and the control data is transmitted to the UAV at a second frequency band that does not overlap with the first frequency band.

10. The device of claim 8 , wherein the feedback data is transmitted from the UAV within a first time frame of a cycle, and the control data is transmitted to the UAV within a second time frame of the cycle that does not overlap with the first time frame.

11. A system for communicating with an unmanned aerial vehicle (UAV), comprising:
a device located remotely from the UAV, wherein the device is configured to receive feedback data from the UAV and transmit control data to the UAV via a first communication link;
a controlling terminal located remotely from the UAV, wherein the controlling terminal is configured to generate the control data and transmit the control data to the device via a second communication link, wherein the second communication link does not interfere with the first communication link; and
a processor located at the device, wherein the processor is configured to determine whether the feedback data and the control data are being simultaneously transmitted via the first communication link.

12. The system of claim 11 , wherein:
the feedback data includes a feedback data indicator indicating whether a transmission of the feedback data via the first communication link is ongoing or will start soon; and
the control data includes a control data indicator indicating whether a transmission of the control data via the first communication link is ongoing or will start soon.

13. The system of claim 11 , wherein the processor is further configured to terminate a transmission of the control data via the first communication link by shutting down or disabling a receiver of the device when the feedback data and the control data are being simultaneously transmitted via the first communication link, wherein the receiver is configured to receive the control data from the controlling terminal.

14. The system of claim 13 , wherein the termination of the transmission of the control data via the first communication link is further determined based on one or more communication conditions, wherein the one or more communication conditions include at least one of an interference level, a signal-to-noise ratio, or an error rate.

15. The system of claim 11 , wherein the processor is further configured to modify the control data based on the feedback data before transmitting the control data to the UAV.

16. The system of claim 11 , wherein the feedback data includes sensor data or status data indicating an operational state, a speed, a position, or an attitude of the UAV.

17. The system of claim 11 , wherein the first communication link or the second communication link is a wireless communication link or a wired communication link.

18. The system of claim 11 , wherein the feedback data and the control data are transmitted via the first communication link using a frequency division multiplexing (FDM) scheme or a time division multiplexing (TDM) scheme to reduce interference.

19. The system of claim 18 , wherein the feedback data is transmitted from the UAV at a first frequency band, and the control data is transmitted to the UAV at a second frequency band that does not overlap with the first frequency band.

20. The system of claim 18 , wherein the feedback data is transmitted from the UAV within a first time frame of a cycle, and the control data is transmitted to the UAV within a second time frame of the cycle that does not overlap with the first time frame.
