Hi Matt,

 

Thanks for the update.

I have one comment.

In your revised text, especially on 33.x.y.3, isn’t the first paragraph a subset of the second paragraph?

 

Best,

Young Hoon

Hello,

 

I've made a small addition.

 

I've added another AP should not transmit to an NSTR MLD in the case of when the AP might be able to determine that some STA of the NSTR MLD is actively transmitting to anybody else (i.e. currently, it only mentions transmitting to the AP, because that's easy for the AP to figure out) but it is possible that maybe the AP can see the non-AP transmitting for example, a P2P on a link and the AP might be able to decode the EHT PPDU header AID and Color or something in the MAC header that tells it that this is a TX by the non-AP MLD and if it can do that, then again, the AP should not TX to that NSTR non-AP MLD - so this new should not applies only when the AP is able to make that determination.

Dear Matthew and Kaiying,

 

I saw R2, and it seems to reflect SFD well.

Thank you for your hard work.

Hi Matt and Sanghyun,

 

I agree with Sanghyun’s comment. The SFD gave the condition on which the responder is allowed to make a choice. But the condition is that the another STA affiliated with the NSTR MLD is participating an TXOP on that link. Without this condition, the NSTR responder shall respond CTS if NAV is idle on this link.

 

I think the draft text should reflect this condition.

 

Thanks,

Kaiying

Sanghyun,

 

1) 

 

missing "." added

 

2)

 

your comment:

text does not cover “the STA may not respond with a CTS frame." of the SFD. (We need some “may” for a STA with NSTR contrained)    

 

the SFD text bothers me

 

a. I agree that the SFD says "may" not respond, which appears to allow for the responder to make a choice

b. I agree that doc 1395r0 does not provide a choice to the responder, but instead, always dictates, depending on conditions, that there either shall or shall not be a CTS

 

When reading the SFD, I assumed that the language was imprecise.

 

I will create a version which provides the choice as an alternative, assuming that the SFD expresses exactly what the body desired, i.e. that the responder has a choice.

That will be version r2
