Abstract

Some demonstrative embodiments include devices, systems and/or methods of communicating during an Association-Beamforming-Training (A-BFT). For example, a device may include a wireless communication unit to communicate a beacon frame during a beacon transmission interval (BTI), the beacon frame including a responder address field including a responder address representing one or more client devices, which are allowed to transmit during an A-BFT period following the BTI.

Claims (48)

1. A directional multi-gigabit (DMG) station comprising:

a receiver to receive a DMG beacon frame during a beacon transmission interval (BTI) within a DMG beacon interval, the DMG beacon frame including a Basic Service Set Identifier (BSSID) and a clustering control field including a responder address subfield, the responder address subfield including a responder address representing at least one station, which is allowed to transmit during an Association-Beamforming-Training (A-BFT) period following said BTI within said DMG beacon interval; and

a transmitter to transmit during said A-BFT period only if said responder address is equal to a Media-Access-Control (MAC) address of said DMG station, or if said responder address includes a group address of a group to which said DMG station belongs.

2. The DMG station of claim 1 being a client device.

3. The DMG station of claim 2 , wherein said client device comprises a Peer-to-Peer (P2P) client device.

4. The DMG station of claim 1 , wherein said responder address subfield includes an address selected from a group consisting of an address of an individual client device, and a group address of a group of client devices.

5. A directional multi-gigabit (DMG) station comprising:

a transmitter to transmit a DMG beacon frame during a beacon transmission interval (BTI) within a DMG beacon interval, the DMG beacon frame including a Basic Service Set Identifier (BSSID) and a clustering control field including a responder address subfield, the responder address subfield including a responder address representing at least one station (STA), which is allowed to transmit during an Association-Beamforming-Training (A-BFT) period following said BTI within said DMG beacon interval; and

a receiver to receive during said A-BFT period transmissions from said at least one STA.

6. The DMG station of claim 5 , wherein said responder address subfield includes a Media Access Control (MAC) address.

7. The DMG station of claim 5 including a personal basic service set control point (PCP) or access point (AP) station.

8. A system comprising:

a directional multi-gigabit (DMG) station including:

one or more antennas;

a memory;

a processor;

9. The system of claim 8 , wherein said DMG station is a client device.

10. The system of claim 8 , wherein said DMG station comprises an input unit, an output unit, and a storage.

11. The system of claim 8 , wherein said responder address subfield includes an address selected from a group consisting of an address of an individual client device, and a group address of a group of client devices.

12. A system comprising:

a directional multi-gigabit (DMG) station including:

one or more antennas;

a memory;

a processor;

a receiver to receive during said A-BFT period transmissions from said at least one STA.

13. The system of claim 12 , wherein said responder address subfield includes a Media Access Control (MAC) address.

14. The system of claim 12 , wherein said DMG station is a personal basic service set control point (PCP) or access point (AP) station.

15. A method comprising:

receiving at a Direct Multi-Gigabit (DMG) station a DMG beacon frame during a beacon transmission interval (BTI) within a DMG beacon interval, the DMG beacon frame including a Basic Service Set Identifier (BSSID) and a clustering control field including a responder address subfield, the responder address subfield including a responder address representing at least one station, which is allowed to transmit during an Association-Beamforming-Training (A-BFT) period following said BTI within said DMG beacon interval; and

transmitting during said A-BFT period only if said responder address is equal to a Media-Access-Control (MAC) address of said DMG station, or if said responder address includes a group address of a group to which said DMG station belongs.

16. The method of claim 15 , wherein said DMG station comprises a client device.

17. The method of claim 15 , wherein said responder address subfield includes an address selected from a group consisting of an address of an individual client device, and a group address of a group of client devices.

18. A method comprising:

transmitting a direct multi-gigabit (DMG) beacon frame during a beacon transmission interval (BTI) within a DMG beacon interval, the DMG beacon frame including a Basic Service Set Identifier (BSSID) and a clustering control field including a responder address subfield, the responder address subfield including a responder address representing at least one station (STA), which is allowed to transmit during an Association-Beamforming-Training (A-BFT) period following said BTI within said DMG beacon interval; and

receiving transmissions from said at least one STA during said A-BFT period.

19. The method of claim 18 , wherein said responder address subfield includes a Media Access Control (MAC) address.

20. The method of claim 18 being performed by a personal basic service set control point (PCP) or access point (AP) station.

21. A product including a non-transitory storage medium having stored thereon instructions that, when executed by a machine, result in:

22. The product of claim 21 , wherein said responder address subfield includes an address selected from a group consisting of an address of an individual client device, and a group address of a group of client devices.

23. A product including a non-transitory storage medium having stored thereon instructions that, when executed by a machine, result in:

receiving transmissions from said at least one STA during said A-BFT period.

24. The product of claim 23 , wherein said responder address subfield includes a Media Access Control (MAC) address.
