Re: [STDS-802-11-TGBN] Request to defer SP on 26/1704

Hi Guogang,

I also have a question on CIDs 19894/19902.

First, I noticed a field-name typo: the field is Request DL SN Not Transferred — there is no “Next” in the field name.

Also, for value 1, the current text says that the non-AP MLD requests that the next SN is transferred, while §9.4.2.364.2 defines value 1 as a request not to transfer the next SN. So I think that sentence just needs to be flipped.

I also wondered if it might help to simplify the wording of the two cases a bit, just to make the intended behavior easier to follow. Perhaps something like:

If the non-AP MLD sets the Request DL SN Not Transferred field to 0, the current AP MLD shall include the corresponding TID, SN, and PN with each MSDU or A-MSDU that it forwards to the target AP MLD for retransmission of a Data frame whose SN is within the current AP MLD’s transmit window defined by WinStartO and WinEndO.

If the non-AP MLD sets the Request DL SN Not Transferred field to 1, the following operations apply when the DL draining period terminates:

• The current AP MLD shall discard all buffered MSDUs for the non-AP MLD that it has already transmitted, regardless of whether the corresponding MPDUs were successfully received. It may forward the remaining MSDUs, which have not been transmitted, to the target AP MLD in the order in which they arrived at the current AP MLD’s MAC SAP. For each TID, the target AP MLD shall prioritize transmission of these forwarded MSDUs over other MSDUs for the same non-AP MLD and TID.

• The non-AP MLD shall pass all MSDUs or A-MSDUs buffered in the receive reordering buffer to the next stage of MAC processing.

I think this keeps the same intent, but makes the distinction between the value-0 and value-1 cases a little more explicit.

BR,

Kerstin

Hi Binita and Kerstin,

 

Yes, I can defer my SP.  Could you please let me know when you want to defer it to? Hope you can share your comments as soon as possible. I plan to run the SP before October 15. Thanks!

 

 

Regards

Guogang Huang

Hi Guogang,

Could you please defer any SP on 26/1704 (if planned).

 

Need more time to review the document, and I won't be able to dial into the TGbn meeting today.

 

Thanks,

Binita
