Abstract

Embodiments include systems and methods for allocating time to a plurality of devices in the network of a piconet controller. Embodiments comprise selectively directing a steerable antenna beam of the piconet controller to a plurality of devices in succession during a polling process to receive time allocation requests from one or more of the devices. Subsequent to the polling process, a grant procedure is performed wherein a device is granted permission to transmit in a subsequent time interval. Also during the grant process, one or more devices are instructed to receive from the device granted permission to transmit. The polling process and the grant process occur in the same superframe.

Claims

1. A method, comprising:

sending, via a millimeter wave range, a plurality of directive polling messages to each of a plurality of devices one by one in succession;

in response to sending one of the directive polling messages to a source device, receiving a directive transmit request from the source device, the directive transmit request for an intended directive communication to a recipient device;

allocating resource for the intended directive communication;

sending, after receiving the directive transmit request, via the millimeter wave range, a first directive transmission to the source device, the first directive transmission granting permission to send the intended directive communication after completion of polling the plurality of devices one by one in succession, and

sending, after receiving the directional transmit request, via the millimeter wave range, a second directive transmission to the recipient device, the second directive transmission granting permission to receive to the intended directive communication;

wherein the source device is one of the plurality of devices that received directive polling messages.

2. The method of claim 1, wherein sending a plurality of directive polling messages comprises steering an antenna beam.

3. The method of claim 1, wherein allocating the resource comprises allocating a time duration.

4. The method of claim 3, wherein the time duration is in a superframe.

5. The method of claim 1, wherein the first directive communication and the second communication are sent within a same superfrarne duration.

6. The method of claim 1, wherein the directive transmit request comprises a requested transmit time duration.

7. The method of claim 1, wherein said plurality of directive transmissions are sent in a round robin manner.

8. An apparatus, comprising:

a transceiver to;

send, via a millimeter wave range, a plurality of directive polling messages to each of a plurality of devices one by one in succession,

in response to sending one of the directive polling messages to a source device, receive a directive transmit request from the source device, the directive transmit request for an intended directive transmission to a recipient device,

send, after receiving the directive transmit request, via the millimeter wave range, a first directive communication to the source device, the first directive communication granting permission to send the intended directive transmission after completion of polling the plurality of devices one by one in succession, and

send, after receiving the directive transmit request, via the millimeter wave range, a second directive communication to the recipient device, the second directive communication granting permission to receive to the intended directive transmission; and

a processor to allocate a resource for the intended directive transmission;

wherein the source device is one of the plurality of devices that received directive polling messages.

9. The apparatus of claim 8, wherein the resource comprises a time duration.

10. The apparatus of claim 9, wherein the time duration is in a superframe.

11. The apparatus of claim 8, wherein the first directive communication and the second communication are sent within a same superframe duration.

12. The apparatus of claim 11, wherein the directive transmit request comprises a requested transmit time duration.

13. The apparatus of claim 8, wherein the transceiver is to send the plurality of directive transmissions in a round robin manner.

14. The apparatus of claim 8, further comprising a selectively directive antenna.

15. The apparatus of claim 14, wherein the selectively directive antenna comprises a steerable phased array antenna.

16. A non-transitory machine-accessible medium containing instructions, which, when executed by a machine, cause said machine to perform operations, comprising:

sending a plurality of directive polling messages via a millimeter wave range to each of a plurality of devices one by one in succession;

in response to sending one of the directive polling messages to a source device, receiving a directive transmit request from the source device, the directive transmit request for an intended directive communication to a recipient device;

allocating a resource for the intended directional communication;

sending, after receiving the directive transmit request, via the millimeter wave range, a first directive transmission to the source device, the first directive transmission granting permission to send the intended directive communication after completion of polling the plurality of devices one by one in succession, and

sending, after receiving the directive transmit request, via the millimeter wave range, a second directive transmission to the recipient device, the second directive transmission granting permission to receive to the intended directive communication

wherein the source device is one of the plurality of devices that received directive polling messages.

17. The non-transitory machine-accessible medium of claim 16, wherein allocating the resource comprises allocating a time duration.

18. The non-transitory machine-accessible medium of claim 17, wherein the time duration is in a superframe.

19. The non-transitory machine-accessible medium of claim 16, wherein the first directive communication and the second communication are sent within a same superframe duration.

20. The non-transitory machine-accessible medium of claim 16, wherein the directive transmit request comprises a requested transmit time duration.
