Abstract

When a device in one wireless network receives interfering transmissions from an overlapping neighboring network, the neighboring network may be notified of the interference so that non-interfering schedules can be worked out. In one embodiment, the device receiving the interference may broadcast its own communications schedule. Device(s) in the interfering network may pick up that schedule, and pass it on to their controller, which can rearrange its own network schedule to be non-interfering. In another embodiment, the device receiving the interference may notify its own network controller with the pertinent information, and that controller may contact the controller of the interfering network to coordinate non-interfering schedules.

Claims

1. A method, comprising:

detecting, by a first device configured to operate in a first wireless network, interference to the first device, the interference from a second wireless network; and

transmitting, from the first device, a notification of the interference to a control device of the first wireless network,

wherein the notification indicates a time when the interference occurred.

2. The method of claim 1, wherein the interference is detected during a scheduled reception time in the first wireless network.

3. The method of claim 1, wherein the notification includes an identification of a device causing the interference.

4. The method of claim 1, wherein the first wireless network and the second wireless network at least partially overlap.

5. An apparatus, comprising a first communications device for operating in a first wireless network, the first device to:

detect interference in the first wireless network, the interference from a second wireless network; and

wirelessly transmit a notification of the interference to a control device of the first wireless network,

wherein the notification indicates a time when the interference occurred.

6. The apparatus of claim 5, wherein the first communications device is to detect the interference during a scheduled reception time.

7. The apparatus of claim 5, wherein the notification includes an identification of a device causing the interference.

8. The apparatus of claim 5, wherein the first wireless network and the second wireless network at least partially overlap.

9. A method, comprising:

receiving at a control device of a first wireless network, from a mobile device operable in the first wireless network, an indication of interference to the first mobile device, the interference from a second wireless network; and

sending a notification of the interference from the control device of the first wireless network to a control device of the second wireless network.

10. The method of claim 9, wherein the indication of interference includes an identification of a device causing the interference.

11. The method of claim 9, wherein the indication of interference includes an indication of a time when the interference occurred.

12. The method of claim 9, wherein the first wireless network and the second wireless network at least partially overlap.

13. An apparatus, comprising a first network control device configured to operate in a first wireless network, the first network control device to:

receive, from a first mobile device configured to operate in the first wireless network, an indication of interference to the first mobile device from a second wireless network; and

notify a second network controller of the second wireless network of the interference.

14. The apparatus of claim 13, wherein the indication of interference includes an indication of a time when the interference occurred.

15. The apparatus of claim 13, wherein the indication of interference includes an identification of a device causing the interference.

16. The apparatus of claim 13, wherein the first network control device is to coordinate network schedules with the second network controller based on the interference.

17. The apparatus of claim 13, wherein the first network control device is to adjust a schedule of the first wireless network based on the interference.

18. The apparatus of claim 17, wherein said adjustment is performed independently of the second network controller.

19. The apparatus of claim 13, wherein the first wireless network and the second wireless network at least partially overlap.

20. An article comprising a non-transitory computer-readable medium that contains instructions, which when executed by one or more processors result in performing operations comprising:

causing a first device configured to operate in a first wireless network to detect interference to the first device, the interference from a second wireless network; and

causing the first device to transmit from the first device a notification of the interference to a control device of the first wireless network,

wherein the notification includes a time when the interference occurred.

21. An article comprising a non-transitory computer-readable medium that contains instructions, which when executed by one or more processors result in performing operations comprising:

causing a control device of a first wireless network to receive, from a first mobile device operable in a first wireless network, an indication of interference to the first mobile device, the interference from a second wireless network; and

causing the control device of the first wireless network to send a notification of the interference from the control device of the first wireless network to a control device of the second wireless network.
