[STDS-802-11-TGBN] 回复: [STDS-802-11-TGBN] Seamless roaming PDT Part 3, Part 4, and Part 5



Dear  Duncan

 

         Thank you for preparing these Drafts.

         Please find my comments as below:

 

In PDT part4:

1.Before the ST preparation request, The network prepares these AP MLDs with minimal context such as security keys and expected TA. Why can't the preparation procedure and execution procedure be combined? This approach seems to be more efficient.

 

2. For emergency roaming, can we handle different TID data differently? For instance, high-priority data can be routed through Target AP MLD for roaming, while low-priority data can continue to be transmitted through Current AP MLD.

 

In PDT part 5:

1. The AID in ST preparation response should not be optional present. If at least one link is accepted, SMD BSS Transition Parameters element shall be included in ST prep. response with the mandatory AID field.

 

2. AP transmits UHR Link Reconfiguration Notify (Type=2) frame with  DL data status when DLDrainTime expires. What is DL data status used for? It is useful if non-AP MLD can decide whether to terminate depending on DL data status, which means current AP's UHR Link Reconfiguration Notify frame with DL data status is not a mandatory termination of DLDrainTime

 

3. Why is only the MSCS status included  in Common Info field format of the ST Info field in an ST preparation response? Should other status information such as SCS status and BA status also be included?

 

 

 

 

祝工作顺利!
