Hi Jason,

 

Thanks for your efforts.

 

I'm not sure what's the meaning of "same channel" or you intend to say "same operating channel"?  BTW, Whether C-BF feature also can work when the two APs have the overlapping channel?

 

 

Thanks

 

Best Regards

 

Jay Yang (杨志杰)

Hi Jason,

 

I have a few comments regarding your definition of Co-BF in both 3.2 and 37.8.1.

 

Your definition:

coordinated beamforming: [Co-BF] A procedure that enables two APs in the same neighborhood to perform concurrent transmissions on the same channel using the CSI of the channels between each AP and the recipient STAs.

My comments:

 

  1. How do you define “in the same neighborhood”? Perhaps delete this phrase.
  2. The definition is neither complete nor explicit to Co-BF. Co-BF is not just about using the CSI but also about forming nulls to unintended recipient STAs.
  3. The phrase “the channels between each AP and the recipient STAs” is not clear if the cross-BSS channels between each AP and its unintended recipient STAs are included.

 

 

Another comment is that in the latest skeleton 11-24/1933r3, the Co-BF MAC subclause is 37.7.2. Should your 37.8 subclause be 37.7.2 instead?

 

Regards,

Alice Chen
