Re: [STDS-802-11-TGBN] LB291 - LLI CRs part 1 uploaded



Hi All,
Regarding the following deferred CIDS : (#12585, #5026, #11867, #9307, #8101, #6351, #5663, #5223, #4879, #4827, #9308, #5403, #12583, #11366, #10109, #5662, 11539)

After discussing with multiple members, we have proposed the following replacement text. This new text maintains the same meaning as D1.0 without any technical changes. The comments we are addressing primarily aim to clarify ambiguous language and eliminate confusion.


Please review the text and let me know if you have any comments. 


A non-AP LLI MLD STA shall not establish SCS streams with its associated AP LLI MLD STA where the LLI Request subfield in the QoS Characteristic element is equal to 1 and the Direction subfield in the QoS Characteristic element is equal to UL and direct link.

NOTE—The Direction field of all SCS request frames sent by a non-AP LLI MLD that have the LLI Requested subfield equal to 1 will have the Direction field in the QoS Characteristics element set to the same value (0 or 2). 

If the corresponding non-AP MLD with which the LLI non-AP STA affiliated has an SCS stream established with its associated AP MLD, in which the LLI Requested field in the QoS Characteristics element is equal to 1 and the Direction field in the QoS Characteristics element has a value of 0 (Uplink), an LLI non-AP STA affiliated with the same non-AP MLD shall not establish an SCS stream with its associated LLI AP where the LLI Requested field in the QoS Characteristics element is equal to 1 and the Direction field has a value of 2 (Direct Link).

If the corresponding non-AP MLD with which the LLI non-AP STA affiliated has an SCS stream established with its associated AP MLD, in which the LLI Requested field in the QoS Characteristics element is equal to 1 and the Direction field in the QoS Characteristics has a value of 2 (Direct Link), an LLI non-AP STA affiliated with the same non-AP MLD shall not establish an SCS stream with its associated LLI AP where the LLI Requested field in the QoS Characteristics element is equal to 1 and the Direction field in the QoS Characteristics has a value of 0 (Uplink).

Thanks Dibakar for the comment,
I will take care of that in the next submission

Hi Mohamed,
 
This seems good. Did you also make similar changes to the definition of the LLI Requested subfield ? If not would suggest to make a similar change.
 
 
he LLI Requested field is reserved if the QoS (#12606, #5027, #6347)Characteristics element is sent by a non-UHR non-AP STA or a UHR non-AP STA affiliated with a non-AP MLD that does not contain an affiliated STA which supports LLI or if the Direction subfield is 1(#11174)(Downlink).”

Hi Dibakar,
Thanks for your comments and feedback.
Please see my response below

Hi Mohamed, 
 
Thank you for working on this document. I have a clarification q on this part:
 
“If an LLI non-AP STA has established an SCS stream with its associated LLI AP in which the LLI Requested field in the QoS Characteristics element is equal to 1 and the Direction field in the QoS Characteristics has value  0 (Uplink), the LLI non-AP STA shall not establish an SCS stream with its associated LLI AP in which the LLI Requested subfield in the QoS Characteristics element is equal to 1 and the Direction subfield in the QoS Characteristics has value  2 (Direct Link).”
 
  • There are two bits for LLI indication for UL and P2P respectively. This constraint makes one bit redundant. What is the plan for the frame format : does it stay unchanged still ?
[MA] I would prefer to keep it as is for future updates. We do have many reserved bits and possibly we can enable multi-SCS with different directions in future amendments 

  •  
  • Say, LLI is supported on two links. STA MLD sends SCS Req (UL, LLI = true) on link 1. Is it allowed to send SCS Req (P2P, LLI =  true) on link 2 ? Given that SCS is at MLD level, I assume the intention of the current sentence is for that not to be allowed.  If so, will it be clearer to replace “non-AP STA” with “non-AP STA MLD” above ? Or, with any “STA affiliated with a non-AP MLD” ?
[MA] that its a valid comment. We can update the text as follows, would that be okay for you?
“If an LLI non-AP STA affiliated to a non-AP MLD has established an SCS stream with its associated LLI AP in which the LLI Requested field in the QoS Characteristics element is equal to 1 and the Direction field in the QoS Characteristics has value  0 (Uplink), an LLI non-AP STA affiliated with the same non-AP MLD shall not establish an SCS stream with its associated LLI AP in which the LLI Requested subfield in the QoS Characteristics element is equal to 1 and the Direction subfield in the QoS Characteristics has value  2 (Direct Link).”

Hi all,
This is to update that r6 of 11-25-1918 has been uploaded with some of the deferred SPs updated in green. I am planning to run SP on the green CRs
Thanks,
Mohamed
