Abstract

Various embodiments may be generally directed to resource allocation techniques for beam forming training. In one embodiment, for example, an apparatus may comprise logic for an access point (AP), at least a portion of the logic implemented in circuitry coupled to the memory, the logic to identify one or more resources available to support beamforming operations in a time interval, enable the AP to use the one or more resources in the time interval to interact with one or more allowed classes of station (STA) to perform one or more beamforming operations, and generate a frame for wireless transmission comprising a set of indicator bits encoded with an indication of the one or more resources. Other embodiments are described and claimed.

First claim

What is claimed is:

1. An apparatus, comprising:
a memory; and
circuitry coupled to the memory to implement logic for an access point (AP), the circuitry to:
generate a frame for wireless transmission, the frame comprising a beacon interval control field, the beacon interval control field comprising a cluster control present (CC present) bit and a discovery mode bit; the beacon interval control field to indicate one or more resources available to support beamforming operations in a time interval; the CC present bit to indicate an existence of a cluster control field in a frame body of the frame; the cluster control field to indicate a first class of station (STA), of more than one classes of STA, allowed to perform one or more beamforming operations in the time interval; and
cause the frame to transmit.

2. The apparatus of claim 1 , the one or more resources to include resources available to a second class of STA and to include additional resources available to the first class of STA.

3. The apparatus of claim 2 , the first class of STA to identify the additional resources in a portion of the beacon interval control field that the second class of STA identifies as reserved bits.

4. The apparatus of claim 2 , the first class of STA to comprise one or more non-legacy stations.

5. The apparatus of claim 2 , the second class of STA to comprise one or more legacy stations.

6. The apparatus of claim 1 , the one or more resources to include resources available on a primary channel and resources available on a secondary channel.

7. The apparatus of claim 6 , the one or more resources to include additional resources available to the first class of STA on the secondary channel.

8. The apparatus of claim 1 , the cluster control field to comprise a responder address including a media access control (MAC) address of the AP.

9. The apparatus of claim 1 , the more than one classes of STA comprising directional multi-gigabit (DMG) STAB.

10. The apparatus of claim 1 , the time interval comprising a beacon interval and the frame comprising a DMG beacon frame.

11. The apparatus of claim 1 , the AP comprising a personal basic service set (PBSS) control point (PCP).

12. The apparatus of claim 1 , the one or more beamforming operations comprising association beamforming training (A-BFT).

13. The apparatus of claim 1 , the one or more beamforming operations comprising a transmit sector sweep (TXSS).

14. The apparatus of claim 1 , further comprising a radio interface coupled with the circuitry and antennas coupled with the radio interface.

15. At least one non-transitory computer-readable medium comprising a set of instructions that, in response to being executed by a processor, cause the processor to:
generate a frame for wireless transmission, the frame comprising a beacon interval control field, the beacon interval control field comprising a cluster control present (CC present) bit and a discovery mode bit; the beacon interval control field to indicate one or more resources available to support beamforming operations in a time interval; the CC present bit to indicate an existence of a cluster control field in a frame body of the frame; the cluster control field to indicate a first class of station (STA), of more than one classes of STA, allowed to perform one or more beamforming operations in the time interval; and
cause the frame to transmit.

16. The at least one non-transitory computer-readable medium of claim 15 , the one or more resources to include resources available to a second class of STA and to include additional resources available to the first class of STA.

17. The at least one non-transitory computer-readable medium of claim 16 , the first class of STA to identify the additional resources in a portion of the beacon interval control field that the second class of STA identifies as reserved bits.

18. The at least one non-transitory computer-readable medium of claim 16 , the first class of STA to comprise one or more non-legacy stations.

19. The at least one non-transitory computer-readable medium of claim 16 , the second class of STA to comprise one or more legacy stations.

20. The at least one non-transitory computer-readable medium of claim 15 , the one or more resources to include resources available on a primary channel and resources available on a secondary channel.

21. The at least one non-transitory computer-readable medium of claim 20 , the one or more resources to include additional resources available to the first class of STA on the secondary channel.

22. The at least one non-transitory computer-readable medium of claim 15 , the cluster control field to comprise a responder address including a media access control (MAC) address of the AP.

23. The at least one non-transitory computer-readable medium of claim 15 , the more than one classes of STA comprising directional multi-gigabit (DMG) STAB.

24. The at least one non-transitory computer-readable medium of claim 15 , the time interval comprising a beacon interval and the frame comprising a DMG beacon frame.

25. The at least one non-transitory computer-readable medium of claim 15 , the AP comprising a personal basic service set (PBSS) control point (PCP).

26. The at least one non-transitory computer-readable medium of claim 15 , the one or more beamforming operations comprising association beamforming training (A-BFT).

27. The at least one non-transitory computer-readable medium of claim 15 , the one or more beamforming operations comprising a transmit sector sweep (TXSS).
