Hi Cheng, Thanks for the clarification regarding your consideration in not using UL/DL. I am fine with that, as long as I2R and R2I do not imply 11az NDP. I believe you still need to differentiate between the two NDPs, right? If you want to keep
the 2 terms as generic terms to indicate the NDP direction, perhaps the note can be modified as below then:
Regards, Rojan From: Chen, Cheng <cheng.chen@xxxxxxxxx> Hi Rojan, Thanks for your comments. First of all, the motion text is definitely not trying to restrict the NDP formats to a specific one. I understand that currently the formats of the NDP are still pending discussions and not decided yet, similar to the NDPF frame format.
We already have a few contributions from multiple members talking about this topic and we will see which format we eventually choose. Therefore, I am fine to add the note saying “NDP formats are TBD”. Regarding changing the I2R and R2I to UL and DL. I believe we talked about this when we were discussing the TB measurement instance. Originally I was also using the word “UL NDP sounding” and “DL NDP sounding” in TB measurement instance,
but then after discussions in 11bf we changed the wording to “TF sounding” and “NDPA sounding” respectively. Following the same ideas, I am trying not to use “UL” and “DL” here in non-TB measurement sequence. I think as long as we make it clear that “NDP formats
are TBD”, then we don’t have the confusion that the I2R and R2I NDP here are restricted to HE Ranging NDP, which is not our intention either. Regarding your other editorial suggestions, I am fine with them. Best, Cheng From: Rojan Chitrakar <rojan.chitrakar@xxxxxxxxxxxxxxxx>
Dear Cheng, Sorry, I couldn’t attend the session where the SP was ran and couldn’t provide my feedback earlier.
I have some concerns on the use of the terms “I2R NDP” and “R2I NDP”, is it necessary to limit the NDP to the HE ranging PPDU format? I2R NDP and R2I NDP restricts the usage to 160 MHz. E.g., the NDP could very well be EHT sounding PPDU
also which can go up to 320 MH, right. I believe its not your intention to restrict the usage of other NDPs, e.g. EHT NDP. I suggest we simply use UL/DL NDP instead and also clarify that the NDP format is TBD, as is done in other motions in the SFD. I believe the meaning of the motion stays the same. Something like below: Move to add the following to the TGbf SFD:

Hi Tony, I received an offline comment and would like to update the motion text as follows.
Move to add the following to the TGbf SFD:
The comment is that the current text may confuse people because it sounds like whenever a non-AP STA gets a TXOP, it must always initiate a non-TB sensing measurement instance, which is surely not what I am trying to propose. The modified
text will avoid such confusion and make it more clear. Best, Cheng From: Chen, Cheng Hi Tony, I would appreciate if you could run the motion below in a future meeting as appropriate. Thanks. The reference document is 11-21/1433r2. SP result was 19/4/13. Move to add the following to the TGbf SFD:
