Re: [STDS-802-11-TGBE] PDT MAC MLO Discovery: ML IE Structure

Hi Jarkko,

You raised a few good points. Jay brought up the same concerns.

I am going with the group's decision. There is a motion that says it is TBD.
Once the group decides that a Beacon (and non-ML Probe Response) frame always includes ML IE, I will update the text accordingly.

The Multi-Link element when included in a Beacon or non-ML Probe Response frame should carry only MLD-level/common information.

*         NOTE: Exact name for the element is TBD.

*         NOTE: Whether the Multi-Link element is always present in the Beacon and non-ML Probe Response frames or is optionally present is TBD.

*         NOTE: MLD-Level/Common information includes at least MLD Address, and other information (TBD).
[Motion 119, #SP111, [5] and [118]]


If it helps, we could go with the following so that we can revisit this topic:
Table 9-34-Table 9-34 - Beacon frame body
Order
Information
Notes
<ANA>
Multi-Link
The Multi-Link element is optionally (TBD) present if the reporting AP is affiliated with an AP MLD. Otherwise it is not present.

I'm open to suggestions.

Regards,
Abhi

Hi Abhi, all,

                One question:
[cid:image002.png@01D68AA2.0E74F7D0]

                1. Is the multi-link element really optional in Beacon and in Probe Response?
                 I though that this element is transmitted in all Beacons of AP belonging to AP MLD:
                                - non-AP STA MLD may be confused, if the element is sometimes present and sometimes not present. It is better to have this element always present.
                                - if this element is not present in Beacon, then can receiving STAs detect that the AP sending the beacon is part of the AP MLD?
                                - Can non-AP MLDs initiate link setup based on the received Beacon? In legacy operation, STAs have been able to association if they receive Beacon or probe response.


                Cheers,
                Jarkko
