Re: [STDS-802-11-TGBN] MAC PDT: CID Resolution CC50 for Co-RTWT

Hi Giovanni, Gaius,

Thank you for the good discussions!

My understanding is that the shall rule doesn’t include control response frames, as the control response frame doesn’t rely on the CW mentioned in the 2nd half. It'll be good to clarify this aspect to avoid impacts or regression to legacy STAs that transmit uplink data to the AP.

Thanks,
Yanjun

Hi Giovanni,

 

If that’s the case, I’m wondering does the second part of the sentence still apply (e.g., for an Ack)?

“””

… shall defer transmission by selecting a random backoff count using the present CW[AC] (without advancing to the next value of CW[AC]).

“””

 

Best regards,
Gais

Hi Gaius,

 

Thanks for the question,

I have the same understanding that you have, since it is ‘any PPDU’.

 

Best,

Giovanni

Hi Giovanni,

 

May I just clarify regarding this text:

“””

In addition, before starting transmission of any PPDU, the Co-RTWT coordinated AP shall check if there is enough time for the frame exchange to complete prior to the start of the R-TWT SP and, if there is not enough time, then the Co-RTWT coordinated AP shall defer transmission by selecting a random backoff count using the present CW[AC] (without advancing to the next value of CW[AC]). The QSRC[AC] for the MSDU or A-MSDU is not affected

“””


I realize that this is copied from 11be but “any PPDU” seems to include immediate responses such as Ack frames. Is that a correct interpretation?

 

Best regards,
Gaius
