Hi Ray Thanks for the comments, and sorry for the late response. Let me explain those bits.
Firstly, those bits in SSW/S-SSW are used to tell the AP that, the frames that are carrying those bits can be used for passive sensing, which holds a slightly different
meaning as the indication bit in the association req/resp. Secondly, one thing that may hurt if those bits are not used in SSW/S-SSW is that, the AP cannot use the SSW/S-SSW transmitted during A-BFT for passive sensing when
the non-AP STA enters the BSS trying to associate with the AP. Well, I will keep your comment in mind, while trying to improve the proposal. Thanks,

Hi Naren, Thank you for reaching out for technical comments.
My concern is still using the reserve the bit(s) in SSW and short SSW which has only one reserved bit left. Also, SSW/short
SSW are used for beam tracking procedure, in which those bits are not useful at all. I see the advantage of using those bits in SSW for passive sensing. However, I don’t see major disadvantage if those bits
are not used. Using a bit in the capability indication during the association request/response phase appears sufficient.
Hope I didn’t miss anything. I would appreciate it if you can elaborate further.

Hi Solomon Thank you for your comments. I understand your concern. I would like to respond as follows.
1.
Potential scenario:
A-BFT is used when a non-AP STA firstly enters the BSS (need to do SLS), or the link is lost (need to redo the SLS). AP could use the SSW/Short SSW during A-BFT to do passive sensing.
2.
Practical use and benefit:
Although it seems that A-BFT may only happen once for a specific non-AP STA, it is useful since:
a)
From the perspective of the AP, it can receive transmissions for sensing in different SSW slots from multiple non-AP STAs placed in different locations,
which can be helpful especially in dense environment.
b)
Even A-BFT may only happen once for a specific non-AP STA, it can provide a snapshot of the environment, which can be
i. used as the initial reference to select the proper STAs and/or Beams for specific area/target
ii. combined with the follow up sensing measurement results, to do further processing
for sensing
3.
Future work in consideration:
as suggested by Assaf/Solomon/Claudio and some other group members, we will continue to think about passive sensing as a whole, e.g., not only for BTI/A-BFT, but also DTI.
Since the door for D0.1 is closing, we will continue the work after D0.1, and we may need your further help/discuss to make passive sensing more complete. If you have further concerns, please do let me know. I will be happy to answer them, and we could have a brief discussion, e.g., a call, for me to explain.
Many thanks,

Hi Naren, I have the impression that the effort to provide the DMG passive sensing during A-BFT does not pay off. Let’s see the sequence of the passive sensing to understand why it happens.

WARNING:
This email originated from outside of Qualcomm. Please be wary of any links or attachments, and do not enable macros. Dear all This is Naren from Huawei. During the last 11bf, I’ve presented a PDT for DMG passive sensing based on A-BFT to provide further information on the contribution.
Based on the SP results, and the fact that I didn’t receive any technical question during the call, I genuinely encourage our TGbf friends
who voted no and those who still have
technical concerns to contact me and share your thoughts, which will be much appreciated. I will be more than happy to have a discussion.
If I don’t receive any technical question or concern, I will
run the SP again for the PDT, during the following 11bf call on Thursday. Many thanks, Naren To unsubscribe from the STDS-802-11-TGBF list, click the following link:
