Hi  Hongwon,

Thanks for initiating the discussion. 

Following up on the resolution of CID 11184, the following paragraph implies that the BSS_COLOR parameter (if it exists) in the Co-TDMA TB ICR sent by the polled AP is set to the BSS color of the coordinating AP. 

In this case, I assume the non-AP STAs associated with the polled AP would classify the PPDU carrying this ICR as an inter-BSS PPDU if they only decode the PHY preamble. Do we need to clarify this NAV setting explicitly?

A [홍이1] polled AP that responds to a Co-TDMA TB ICF sets the TXVECTOR parameters as defined in 37.4.2.3.2 (TXVECTOR parameters for UHR TB PPDU response to Trigger frame), where the rules related to a UHR non-AP STA also apply to a polled AP.

Hi All,

 

Thank you for the discussion during CC yesterday. I would like to have an offline discussion regarding deferred CIDs 7622 and 1184

 

We have two discussion points so far

Regarding the issue related to setting the NAV, Sanket raised a concern about unexpected same AP ID in a BSRP Trigger frame from another Coordinating Co-TDMA AP

To address the issue, I removed the exception in 37.2.1, "Setting and resetting the NAV with BSRP Trigger frame and BSRP NDP Trigger frame (#11691)," and added the exception only for Co-TDMA in 37.4.3

 

Here, I added one more condition related to TA of the Co-TDMA coordinating AP

Together with the exception added in 26.2.4, I hope CID 7622 can be resolved

 

Regarding “37.4.3 MU operation for Multi-AP Coordination,” I changed the title to “37.4.3 MU operation for Coordinated Time Division Multiple Access (Co-TDMA) Multi-AP Coordination” to clarify that this subclause applies only to Co-TDMA

Please see attached CR doc(rev9)

 

Please feel free to reach out if you have any comments or questions

 

Best Regards,

Hongwon
