Device, system and method of communicating during an association beamforming training (A-BFT) period
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.
1. An apparatus comprising a transmitter and a receiver, the apparatus configured to cause a directional multi-gigabit (DMG) station to:
receive a DMG beacon frame in a beacon transmission interval (BTI) within a beacon interval, the DMG beacon frame including a Basic Service Set Identifier (BSSID) and a clustering control field including an Association-Beamforming-Training (A-BFT) responder address subfield, the A-BFT responder address subfield including an address to indicate at least one station (STA), which is allowed to transmit during an A-BFT period following said BTI within said beacon interval; and
transmit in said A-BFT period, if a Media-Access-Control (MAC) address of said DMG station is equal to the address in the A-BFT responder address subfield, or if the address in the A-BFT responder address subfield includes a group address of a group to which said DMG station belongs.
2. The apparatus of claim 1 to cause the DMG station to transmit in said A-BFT period, only if at least one of the following conditions are met:
the MAC address of said DMG station is equal to the address in the A-BFT responder address subfield;
the address in the A-BFT responder address subfield includes the group address of the group to which said DMG station belongs.
3. The apparatus of claim 1 , wherein said A-BFT responder address subfield is 48 bits long.
4. The apparatus of claim 1 , wherein said A-BFT period is between said BTI and an announcement transmission interval (ATI).
5. The apparatus of claim 1 , wherein the A-BFT responder address subfield includes an address selected from a group consisting of an address of an individual station, and a group address of a group of stations.
6. The apparatus of claim 1 including at least one antenna.
7. An apparatus comprising a transmitter and a receiver, the apparatus configured to cause a directional multi-gigabit (DMG) station to:
generate a DMG beacon frame including a Basic Service Set Identifier (BSSID) and a clustering control field including an Association-Beamforming-Training (A-BFT) responder address subfield, the A-BFT responder address subfield to indicate a station (STA), which is allowed to transmit during an A-BFT period following a beacon transmission interval (BTI) in a beacon interval; and
transmit the DMG beacon frame in the BTI.
8. The apparatus of claim 7 , wherein said A-BFT responder address subfield is 48 bits long.
9. The apparatus of claim 7 , wherein said A-BFT period is between said BTI and an announcement transmission interval (ATI).
10. The apparatus of claim 7 , wherein the A-BFT responder address subfield includes an address selected from a group consisting of an address of an individual station, and a group address of a group of stations.
11. The apparatus of claim 7 to cause said DMG station to receive a transmission from said STA during the A-BFT period.
12. The apparatus of claim 7 , wherein the DMG station is a personal basic service set control point (PCP) or access point (AP) station.
13. The apparatus of claim 7 including at least one antenna.
14. A product including a non-transitory storage medium having stored thereon instructions that, when executed by one or more processors, result in a method including:
receiving at a directional multi-gigabit (DMG) station a DMG beacon frame in a beacon transmission interval (BTI) within a beacon interval, the DMG beacon frame including a Basic Service Set Identifier (BSSID) and a clustering control field including an Association-Beamforming-Training (A-BFT) responder address subfield, the A-BFT responder address subfield including an address to indicate at least one station (STA), which is allowed to transmit during an A-BFT period following said BTI within said beacon interval; and
transmitting in said A-BFT period, if a Media-Access-Control (MAC) address of said DMG station is equal to the address in the A-BFT responder address subfield, or if the address in the A-BFT responder address subfield includes a group address of a group to which said DMG station belongs.
15. The product of claim 14 , wherein the method comprises transmitting in said A-BFT period, only if at least one of the following conditions are met:
the MAC address of said DMG station is equal to the address in the A-BFT responder address subfield;
the address in the A-BFT responder address subfield includes the group address of the group to which said DMG station belongs.
16. The product of claim 14 , wherein said A-BFT responder address subfield is 48 bits long.
17. The product of claim 14 , wherein said A-BFT period is between said BTI and an announcement transmission interval (ATI).
18. The product of claim 14 , wherein the A-BFT responder address subfield includes an address selected from a group consisting of an address of an individual station, and a group address of a group of stations.
19. A product including a non-transitory storage medium having stored thereon instructions that, when executed by one or more processors, result in a method including:
generating a directional multi-gigabit (DMG) beacon frame including a Basic Service Set Identifier (BSSID) and a clustering control field including an Association-Beamforming-Training (A-BFT) responder address subfield, the A-BFT responder address subfield to indicate a station (STA), which is allowed to transmit during an A-BFT period following a beacon transmission interval (BTI) in a beacon interval; and
transmitting the DMG beacon frame in the BTI.
20. The product of claim 19 , wherein said A-BFT responder address subfield is 48 bits long.
21. The product of claim 19 , wherein said A-BFT period is between said BTI and an announcement transmission interval (ATI).
22. The product of claim 19 , wherein the A-BFT responder address subfield includes an address selected from a group consisting of an address of an individual station, and a group address of a group of stations.
23. The product of claim 19 , wherein the method comprises receiving a transmission from said STA during the A-BFT period.
24. The product of claim 19 , wherein the method comprises transmitting the DMG beacon from a personal basic service set control point (PCP) or access point (AP) station.
