Media access control range extension

1. A device, the device comprising memory and processing circuitry configured to:

cause to append a training field to at least one of one or more beacon frames;

cause to send the one or more beacon frames directionally using a sector sweep to one or more responder devices during a first interval;

determine an extended schedule element to be sent to the one or more responder devices, the extended schedule element including a field indicating one or more directional antenna sectors allocated by the device for receiving communications from the one or more responder devices during a second interval;

identify a first frame from a first responder device, during the second interval, wherein the first frame is received on a directional antenna sector of the one or more directional antenna sectors corresponding to an operating sector of the first responder device; and

cause to send a first acknowledgment frame to the first responder device, wherein the first acknowledgment frame acknowledges reception of the first frame.

2. The device of claim 1 , wherein the training field is used to train the one or more responder devices to determine their respective operating sector during the first interval.

3. The device of claim 1 , wherein the first acknowledgment frame is sent in a direction of the operating sector of the first responder device.

4. The device of claim 1 , wherein the first interval is a beacon transmission interval.

5. The device of claim 1 , wherein the second interval includes directional allocations and quasi-omni allocations.

6. The device of claim 5 , wherein the directional allocations comprise at least one of a contention based period or a scheduled service period.

7. The device of claim 1 , wherein the second interval is a data transmission interval.

8. The device of claim 1 , further comprising a transceiver configured to transmit and receive wireless signals.

9. The device of claim 8 , further comprising one or more antennas coupled to the transceiver.

10. A non-transitory computer-readable medium storing computer-executable instructions which when executed by one or more processors result in performing operations comprising:

identifying, through one or more antenna sectors, one or more directional beacon frames of a sector sweep received from a device in a first interval, wherein at least one of the one or more beacons frame comprises a training field;

determining an operating sector of one or more antenna sectors based at least in part on a comparison between transmission and reception paths of the one or more directional beacon frames;

identifying an extended schedule element including a field indicating the directional antenna sectors to be allocated by the device for receiving communications during a second interval;

causing to send a frame using the directional antenna sectors during the second interval; and

identifying a first acknowledgment frame from the device, wherein the first acknowledgment frame acknowledges reception of the frame.

11. The non-transitory computer-readable medium of claim 10 , wherein the first interval is a beacon transmission interval.

12. The non-transitory computer-readable medium of claim 10 , wherein the second interval is a data transmission interval.

13. The non-transitory computer-readable medium of claim 10 , wherein the second interval includes directional allocations and quasi-omni allocations.

14. The non-transitory computer-readable medium of claim 13 , wherein the directional allocations comprise at least one of a contention based period or a scheduled service period.

15. The non-transitory computer-readable medium of claim 10 , wherein the operations further comprise identifying a training field included in at least one of the one or more directional beacon frames.

16. The non-transitory computer-readable medium of claim 10 , wherein the extended schedule element includes one or more directional allocations by the device.

17. A method comprising:

causing to append, by one or more processors, a training field to at least one of one or more beacon frames;

causing to send the one or more beacon frames directionally using a sector sweep to one or more responder devices during a first interval;

determining an extended schedule element to be sent to the one or more responder devices, the extended schedule element including a field indicating one or more directional antenna sectors allocated by the device for receiving communications from the one or more responder devices during a second interval;

identifying a first frame from a first responder device, during the second interval, wherein the first frame is received on a directional antenna sector of the one or more directional antenna sectors corresponding to an operating sector of the first responder device; and

sending a first acknowledgment frame to the first responder device, wherein the first acknowledgment frame acknowledges reception of the first frame.

18. The method of claim 17 , wherein the training field is used to train the one or more responder devices to determine their respective operating sector during the first interval.

19. The method of claim 17 , further comprising sending a first acknowledgment frame to the first responder device, wherein the first acknowledgment frame acknowledges reception of the first frame.
