Hi Claudio, Thanks for the comments. I am carefully studying your suggestions and advice. Solomon Trainin +972547885738 From: Claudio Da Silva <000015f3cbee3aeb-dmarc-request@xxxxxxxx>
WARNING:
This email originated from outside of Qualcomm. Please be wary of any links or attachments, and do not enable macros. Hi Solomon, Please find a few technical comments on your contributions 1321r1 and 1322r1 below. I would appreciate if you could consider them. Thanks, Claudio My understanding of 1321 and 1322 is that the following changes are being proposed:
If my understanding is correct, I would encourage you to modify the text of the SP found in 1321 to clarify the scope of the proposed changes (redefinition + addition). The proposed “WLAN sensing procedure” incorporates both TB and non-TB approaches. While both approaches have been discussed in TGbf in the past, only the TB approach has been approved by the group so far (motion 25c). Thus, it is important
to call the group’s attention to the fact that a consequence of approving the changes suggested in 1322r1 would be to define a non-TB approach. The WLAN sensing procedure defined in 1321 is composed of a number of “elements”/”phases” (slide 5), many of which haven’t been discussed in TGbf yet. As a result, several sub-sections proposed to be included in the SFD in 1322 are understandably
empty. At the same time, 1322 includes text for both “WLAN sensing measurement setup termination” and ”WLAN sensing session termination phase.” This topic (termination) is not discussed in 1321 nor in any previous contribution to TGbf. Could you discuss
the proposed addition in 1321 (or in a future contribution)? So that 1321 and 1322 match, “WLAN sensing termination” (defined in 1322) must be defined to include/be composed of “WLAN sensing measurement setup termination” and “WLAN sensing session termination” (defined in 1321). (This is similar
to what is proposed for the setup: “The WLAN sensing procedure setup includes the WLAN sensing session setup and the WLAN sensing measurement setup as defined below (7.1.2, 7.1.3)”.) On page 2 of 1322, we have “A sensing session is (a) pairwise agreement between a sensing initiator and a sensing responder to participate in the WLAN sensing procedure.” Given that the text defines that “a sensing session is … agreement
between a sensing initiator and a sensing responder…”, is the word “pairwise” necessary here? (Please note that “pairwise” is defined in 802.11-202, page 167, as a term “used to refer to a type of encryption key hierarchy pertaining to keys shared by only
two entities.”) It may be worth to modify “A sensing session is pairwise and is identified by MAC addresses and/or associated AID/UID” as well (delete “is pairwise and” is OK given that this is already defined in the previous statement). In 1322, the text “NDP can be used for the channel measurement (e.g. CSI)…” is suggested to be moved under “NDPA sounding phase.” Should it also be added to “TF sounding phase”?
In 1322, the sentence “A sensing session may be comprised of multiple burst instances” is suggested to be replaced with “A WLAN sensing measurement instance may be comprised of multiple phases”. Is this the intent of the original SFD text? To unsubscribe from the STDS-802-11-TGBF list, click the following link:
