Abstract

Some demonstrative embodiments include apparatuses, systems and/or methods of selectively responding to wireless communication transmissions. For example, an apparatus may include a wireless communication unit to allocate at least one association beamforming training (A-BFT) period, to receive a responder beamforming transmission from a responder device during the A-BFT period, to transmit to the responder device a feedback transmission in response to the responder beamforming transmission, and to set a responder filtering period extending over one or more successive A-BFT periods, wherein the wireless communication unit is to ignore one or more responder beamforming transmissions from the responder device during the filtering period.

Claims

1. An apparatus comprising:

a wireless communication unit to allocate at least one association beamforming training (A-BFT) period, to receive a first Sector Sweep (SSW) transmission from a first responder device during a first A-BFT period, to transmit to said first responder device a SSW feedback transmission in response to said first SSW transmission, and to set a first responder filtering period extending over one or more successive A-BFT periods, wherein said wireless communication unit is to ignore one or more SSW transmissions from said first responder device during said first responder filtering period, the wireless communication unit is to receive a second SSW transmission from a second responder device during a second A-BFT period, and to set a second responder filtering period, said second A-BFT period is successive to said first A-BFT period, and a beginning time of said second responder filtering period is later than a beginning time of said first responder filtering period, said wireless communication unit is to align an end time of said second responder filtering period with an end time of said first responder filtering period.

2. The apparatus of claim 1, wherein said wireless communication unit is to exchange a probe request and a probe response with said first responder device subsequent to said first SSW feedback transmission, and to set said first responder filtering period subsequent to the exchange of said probe request and said probe response.

3. The apparatus of claim 1, wherein said wireless communication unit is to ignore all SSW transmissions from said first responder device during said first responder filtering period.

4. The apparatus of claim 1, wherein said wireless communication unit is to respond to SSW transmissions from said first responder device only after said first responder filtering period.

5. The apparatus of claim 1, wherein said wireless communication unit is to respond to one or more other SSW transmissions from said first responder device during said first responder filtering period.

6. The apparatus of claim 1, wherein said wireless communication unit is to ignore one or more probe requests from said first responder device during said first responder filtering period.

7. The apparatus of claim 1, wherein said wireless communication unit is to respond to probe requests from said first responder device only after said first responder filtering period.

8. The apparatus of claim 1, wherein said wireless communication unit is to truncate said first responder filtering period.

9. The apparatus of claim 1, wherein a duration of said first responder filtering period is longer than a duration of a beacon interval.

10. The apparatus of claim 9, wherein the duration of said first responder filtering period is at least three times longer than the duration of said beacon interval.

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

allocating at least one association beamforming training (A-BFT) period;

receiving a first Sector Sweep (SSW) transmission from a first responder device during a first A-BFT period;

transmitting to said first responder device a SSW feedback transmission in response to said first SSW transmission;

setting a first responder filtering period extending over one or more successive A-BFT periods; and

ignoring one or more SSW transmissions from said first responder device during said first responder filtering period,

the instructions, when executed, result in receiving a second SSW transmission from a second responder device during a second A-BFT period, and setting a second responder filtering period, said second A-BFT period is successive to said first A-BFT period, and a beginning time of said second responder filtering period is later than a beginning time of said first responder filtering period, said instructions, when executed, result in aligning an end time of said second responder filtering period with an end time of said first responder filtering period.

12. The product of claim 11, wherein said instructions result in exchanging a probe request and a probe response with said first responder device subsequent to said first SSW feedback transmission, and setting said first responder filtering period subsequent to the exchange of said probe request and said probe response.

13. The product of claim 11, wherein said instructions result in responding to SSW transmissions from said first responder device only after said first responder filtering period.
