Hi Cheng, I also have a question regarding the motion; as we discussed in the past, I believe the motion is based on 11az ranging procedure and STAs that do not support/implement 11az will not be able to participate, right? If so, could we make that clear in the motion text, perhaps as a Note: Note: The above Trigger-based sensing measurement instance is optional for pre-11az STAs. Thanks. Regards, Rojan From: Chen, Cheng <cheng.chen@xxxxxxxxx> Hi Xiandong, The word “optional” basically means the presence of UL and DL sounding depends on whether there is at least one sensing transmitter or sensing receiver that responds in the polling process. If there is no STA that is a sensing transmitter
responded in the polling, then there is no UL sounding part; if there is no STA that is a sensing receiver responded in the polling, there is no DL sounding part.

Hi Cheng, I have a clarification question regarding the wording “optional” in 2nd bullet and 3rd bullet of the motion text, my interpretation is that a STA can optionally send the UL
sounding frame even though it indicated its availability and transmitted in the polling procedure. Best Regards, Xiandong Dong 发件人: Chen, Cheng <cheng.chen@xxxxxxxxx>
Hi Tony, I would like to submit the following motion request based on the SP result (26Y 0N 13A) I ran today. Motion: Move to add the following to 11bf SFD:
·
11bf shall define a Trigger-based sensing measurement instance including the following:
o
A polling process where an AP sends a Trigger frame to check the availability of STAs. If a STA is available, it responds with a CTS-to-self.
o
An optional UL sounding where an AP sends a Trigger frame to solicit NDP transmission(s) from STA(s).
§
The UL sounding is present if at least one STA that is a sensing transmitter responds in the polling.
o
An optional DL sounding where an AP sends NDPA frame followed by NDP to STA(s).
§
The DL sounding is present if at least one STA that is a sensing receiver responds in the polling.
o
The order of the UL and DL sounding is TBD.
o
The details of the format of the Trigger frame and the NDPA frame are TBD. Best, Cheng From: Hanxiao (Tony, WT Lab) <tony.hanxiao@xxxxxxxxxx>
