If a definition is needed, it should be clear.

A simple definition may be best: affiliated AP: An affiliated station (STA) in a multilink device (MLD) access point (AP).

This said I still have the following concerns:

There seems to be some confusion as to what an affiliated AP is.

Is it an affiliated STA that is in an MLD AP? If so, why is a different term necessary?
Is it somehow different than an affiliated STA? If so, how?

Is it a logical entity?

If it is a logical entity the definition should probably say so.
If it is a physical entity, then that should be stated.

Depending on the answers to the question above and what is agreed as the definition (if any) the use of the term in the draft should be reviewed.
The statement “and provides additional high medium access control (MAC) services for legacy STA.” is true for the physical MLD device, as the physical device will likely contain several logical entities all supported by the physical device, but for the MLD (which I believe is a logical entity) this is not true. So, while a physical implementation of an MLD will likely support “legacy operation” with the following logical devices: 1 legacy AP for each channel (RF link) supported by the MLD, at least 1 MLD AP that has 1 “affiliated AP” for each channel supported by the MLD; the logical entity (the MLD AP) does. This set of logical devices contained in the physical entity will support “legacy” operation for each of the logical entity APs (the legacy APs) in the physical MLD device and a logical MLD AP which will support MLO.

One last thought, while a MLD STA can receive group addressed frames transmitted by the “legacy” APs in the physical MLD device these group addressed frames are not transmitted using MLO processes or procedures and they are received by the MLD STA just as a “legacy” STAs receive them.

The definitions of AP and STA from 802.11-REVme D2.0 for reference:

access point (AP): An entity that contains one station (STA) and provides access to the distribution system services, via the wireless medium (WM) for associated STAs. An AP comprises a STA and a distribution system access function (DSAF).

station (STA): A logical entity that is a singly addressable instance of a medium access control (MAC) and physical layer (PHY) interface to the wireless medium (WM).

NOTE—For IEEE 802.11 purposes, a station is any MAC/PHY entity providing the IEEE 802.11 MAC services. This differs from the IEEE 802 definition of ‘station,’ which includes bridges (or ‘end stations’) that are endpoints of link

layer data traffic.

Mike,

Yes. The second sentence I proposed earlier is not required. Thanks.

Kind regards

Stephen and Jay,

I don't believe this addition does not provide any additional clarification and is not required. It's sufficient to just relate an affiliated AP to the definition of an affiliated STA.

This approach is consistent with other definitions in the clause.

Cheers,

Mike

Jay,

       thank you. I think this is closer, but I would suggest the following:

affiliated AP: An affiliated station (STA) that is an access point (AP) STA. It might provide complete medium access control (MAC) services for legacy STAs.

Thanks.

Kind regards

Stephen

Hi Mike, Stephen,

The highlight test is suggested by Abhi.

How about this?

affiliated AP: An affiliated station (STA) that is an access point (AP) STA and provides additional high medium access control (MAC) services for legacy STA.

Thanks

Hi All,

My preference would be to not include the "highlighted text". With the definition tied back to an affiliated STA the highlighted text does not provide any meaningful additional information.

Cheers,

Mike

Jay,

      apologies for the delay in responding, but I don't think your highlighted text will work. As this is a definition, there is no context and so the term "corresponding" does not work, as the reader does not know that when you have an affiliated AP, there is also an MLD involved. My suggestion is to remove this text. Thanks.

Kind regards

Stephen

Hi Guogang,

I think the definition of affiliated AP should align with the reference mode in subclause 5, like in Figure 5-2b.

affiliated AP: An affiliated station (STA) that is an access point (AP) STA and the corresponding MLD is an AP MLD, and provides additional high medium access control (MAC) services for legacy STA.

Thanks

主题: RE: Discussion on CID 12036

Hi Guogang,

Thank you for initiating this discussion.

As I mentioned in the Webex chat, I am in favor of keeping the existing definition and adding a new definition for an affiliated AP. The new definition will refer back to the existing definition and say that the STA is an AP STA. Since we are providing definition for an affiliated AP, why not consider affiliated non-AP STA as well?

Something like the following:

affiliated STA: A station (STA), which can be an access point (AP) STA or non-access point (non-AP) STA, that provides link-specific, lower medium access control (MAC) and physical layer (PHY) services within a multi-link device (an MLD).

^^ no change to the existing definition.

               affiliated AP: An affiliated station (STA) that is an access point (AP) STA and the corresponding MLD is an AP MLD.

               affiliated non-AP STA: An affiliated station (STA) that is a non-access point (non-AP) STA and the corresponding MLD is a non-AP MLD.

I am OK if the group decides not to include the highlighted portion.

I am open to consider other suggestions.

Regards,
Abhi

Hi all,

I initial this email thread to discussion the resolution on CID 12306.

Proposed Change

12036

Massinissa Lalam

54

3.2

A definition of affiliated AP is missing, while affiliated STA is defined. Since affilicated AP is used through the whole document (138 times vs 56 times for affiliated STA), may I suggest to add one, e.g.:
affiliated AP: An access point (AP) that provides link-specific, lower medium access protocol (MAC) services within an access point multi-link device (an AP MLD).

As in comment

Generally, there are three options based on received comments:

·        Option 1. Rejected. Because the current definition of affiliated STA already has mentioned “which can be access point (AP) STA or non-access point (non-AP) STA”.

affiliated STA: A station (STA), which can be an access point (AP) STA or non-access point (non-AP) STA, that provides link-specific, lower (#11813)medium access control (MAC) and physical layer (PHY) services within a multi-link device (an MLD)(#10370).

·        Option 2. Revised. Modified the current definition of affiliated STA to cover both affiliated STA and affiliated AP

·        Option 3. Revised. Just add the corresponding definition of affiliated AP and don’t change the current definition of affiliated STA.

Please feel free to provide your thoughts on it.

Guogang Huang
