Re: [STDS-802-11-TGBE] [CR-JOINT] CRs for EHT STA Features

Dear all,

 

I received offline concerns regarding few MAC features and have uploaded a revised version with two possible options. Please review this version instead.

 

https://mentor.ieee.org/802.11/dcn/21/11-21-0299-01-00be-crs-for-d0-3-eht-sta-features-cids.docx

 

To summarize, there are differeing view points regarding the following MAC features, whether they are mandatory for all EHT STAs or only for EHT STAs affiliated with an MLD:

— support for Multi-link discovery procedure

— support for Multi-link (re)setup procedure

— support for Multi-link BlockAck procedure

— support for link management procedure with default TID-to-link mapping

— support for MLD level sequence number spaces

 

To provide some context, I used the following motion as the basis for the above points:

The support of the following MLO features is mandatory for 802.11be AP and 802.11be STA.

  • Discovery procedure, setup procedures, security procedures, default mapping (all TIDs mapped to all links, all setup links enabled), TIM indicating BUs at MLD level, BA at MLD level, power save per link, power state change indications per link, and BSS parameter critical update procedure.
  • NOTE – The above does not preclude other functionalities being added to the list.

[Motion 142, #SP303, [53] and [173]]

 

However, there seem to be different interpretations of the motion, whether it is applicable for all EHT STAs or only for EHT STAs affiliated with MLDs. While there have been attempts in the MAC group to resolve this difference, consensus has not been reached yet. One option is to leave these features out from this CR document for the time being; alternatively we could run a SP for the two options to gauge the group’s preference.

 

Do let me know if you have any thoughts/opinion on this; we could use this thread to see if we can achieve some consensus on this.

 

Best Regards,

Rojan

Dear all,

 

I have uploaded the CR document for CIDs related to clause 4.3.15c (EHT STA features). Please help to review and let me know if there is anything. Thanks to all co-authors that helped to review the draft version and provided valuable feedbacks.
