主题: Re: [STDS-802-11-TGBE] PDT-MAC-MLO-multi-link-setup-usage-and-rules-of-ML-IE
Hi Yongho
Thanks for clarification. Understood.
I think we can refer to the following motion in current SFD.
802.11be defines
a multi-link setup signaling exchange executed over one link
initiated by a non-AP MLD with an AP MLD as follows:
·
Capability for one or more links can be exchanged during the multi-link setup.
·
The AP MLD serves as the interface to the DS for the non-AP MLD after successful multi-link setup.
NOTE 1
– The link identification is TBD.
NOTE 2
– Details for non-infrastructure mode of operation TBD.
[Motion 25, [5] and [102]]
Please let me know if there are some things I miss.
Thanks
Best Regards
Insun.

In my opinion, "single setup signaling exchange" means single exchange of
the Association Request frame and the Association Response frame.
But, the below wording is saying that the Association Request frame and Association Response frame shall be exchanged on the same link. I believe that this is not covered by the current SFD.
I know that both the Authentication and Association shall use the same link. But, in my understanding, this has not been discussed. If I am wrong, can you inform the related document?
Hi Yongho
Thanks for comments.
For describing the single setup, that link was referring to a link on which the Association
Request frame is transmitted described in previous sentences
·
Negotiation of capabilities and operating parameters for multiple links during
a single setup signaling exchange. [Motion 32]
However, I’m updating the texts as follows..
When a non-AP MLD initiates a multi-link setup with an AP MLD, a non-AP STA that is affiliated
with the non-AP MLD shall transmit an (Re-)Association Request frame on the link it is operating on.
When the AP MLD accepts a multi-link setup request from the non-AP MLD, an AP that is affiliated
with the AP MLD and that received the (Re-)Association Request frame shall transmit an (Re-)Association Response frame.
Thanks
Best Regards

"When the AP MLD accepts the association request, an AP that is corresponding to that link
and that is affiliated with the AP MLD shall transmit an (Re-)Association Response frame
on that link."
What does that link mean?
And, which motion covers this red wording? It seems that the red wording is not supported by the motions referred in your document.
Hi Yongho
Thanks. I’m going to try to reflect your suggestion on r4.
Thanks

Thanks for your explanation.
With your assumption, we can consider the current PDT has included that motion. But,
it is just an assumption and that is not agreed yet.
So, to avoid misunderstanding, I kindly suggest to include the same motion text in the next revision.
I see your point. Yongho. That is really different.
Basically, I assume the complete information of reporting STA is already included individually
in EHT capa/operation IE (like legacy).
Therefore, if we have one STA profile subelement, two links would be setup (i.e., more
than one link). So, I’ve described “one or more”
For STA profile subelement in r3, I also added “except for the reporting non-AP STA transmitting
the (Re-)Association Request frame”.
Thanks
Best Regards
Insun

Aren't "more than one" and "one or more"
different?
Because we have
different understanding, I suggest to have the exactly same sentence.
Thanks for pointing it out. Yongho
I see that part “more than one link” is captured in the second paragraph
“The Multi-Link element carried in these frames shall include MLD-level information that
is common to all STAs affiliated with the MLD and one or more STA profile subelement(s) including the specific information of the reported STA(s) corresponding to the link(s) according to the following rules.
(Its sub-paragraphs are also mentioning like that)
Do you happen to want it to be more clear by expressing it explicitly (more than one link)?
Thanks
Best Regards
Insun

My concern is that the following part
is not clear in the PDT.
802.11be supports that a non-AP MLD may initiate multi-link setup with an AP MLD to setup
more than one link with subset of APs affiliated with the AP MLD. This is for R1.
[Motion 122, #SP133, [8] and [129]]
Please let me know which wording is capturing "more than one link". Just including the motion passed text is more clear.
Hi Yongho
Thanks a lot for your comments
I have received the same feedback as your comment.
The motion says like “a non-AP MLD can request subset of APs in AP MLD to setup links”
Therefore, to include the meaning of motion in r3, added the following:
the reported non-AP STA, which is affiliated with the non-AP MLD, corresponding to the link that is requested for multi-link setup (Likewise, on AP MLD side)
If you have further comments/concerns on that, please let me know.
Thanks
Best Regards
Insun

It seems that the following motion is not captured in
your PDT. Could you add that sentence?
802.11be supports that
a non-AP MLD may initiate multi-link setup with an AP MLD to
setup more than one link
with subset of APs affiliated with the AP MLD.
This is for R1.
