[STDS-802-11-TGBN] 回复: [STDS-802-11-TGBN] Seamless roaming PDT Part 5 r1 (signaling format details)



Hi Duncan,

 

Thanks for preparing this PDT. I have several comments.

 

  1. Also need to define a SCS negotiation method by using ST preparation request/response to address the following case, e.g. the current AP MLD doesn’t support the SCS mechanism, but the target AP MLD support the SCS mechanism.
  2. There is no normative behavior when the DL BA Parameters Info is received by the non-AP MLD. It doesn’t make sense to let the transmitter to decide the reordering buffer size of the receiver.
  3. For the following DL TID bitmap field, there is no text to describe the behavior of the current AP MLD for the TID with the corresponding bit equal to 0, especially when the data forwarding is supported.

 

  1. Add the text to clarify the current AP MLD also can send a UHR Link Reconfiguration Notify frame to the non-AP MLD to terminate the DL data retrieval and indicate the reason code
  2. There is no need to do the context transfer and stop the UL data transmission when initiating the ST execution, or there is no roaming execution at all for the centralized SMD. Should signal the SMD Type within the SMD Information element.
  3. Should define DL Data Drain Info as an element and indicate the buffer size for each TID, rather than using a bit indication. This will help the non-AP MLD estimate whether to terminate the DL data retrieval.  

 

Regards

Guogang Huang

Hi all,

 

I’ve updated the PDT Part 5 based on the comments I received during the MAC ad-hoc last week. The revision history in the doc gives a high level summary of the changes.

Could you please let me know if you have any questions or comments?

 

Thanks,

Duncan
