Dear Binita：

 

         Thank you for preparing this Draft.

         Please find my comments as below:

 

1．Could you please explain in detail the differences between Sublayer1 and Sublayer2?

<BG> at the concept level, upper MAC functionality in SMD is split across AP MLD and the SMD-ME. That is what is shown by these two sublayers. 
In case of distributed SMD, main functions in the Sublayer 2 is association management, although this can also be thought as SMD-ME function. The data path upper MAC functions are at each AP MLD.

For centralized mode, Sublayer 2 would perform many of the data path functions (as defined in baseline) for DL/UL data exchange with DS. Exact split of these functions in Sublayer 1 and SUblayer 2 would need further discussion.

 

2．Why in the centralized SMD mode, the MAC-SAP is on Sublayer 2, while in the distributed SMD mode, it is on Sublayer 1?

 

 

<BG> This is as per the architecture agreed in already passed motion for seamless roaming - support a distributed mode that has a MAC-SAP per AP MLD and support a centralized mode that has a single MAC-SAP for the SMD. 

 

Best regards 祝工作顺利！

Hi Alfred,

 

Could you please queue following document in the MAC queue:
- 25/1238: CR for seamless roaming clause 4

 

All - please review and provide any comments you have on this doc.

 

Thanks,
