Hi Rui,
I misread your tracked changes in the previous email. I’m fine with deleting the sentences and start with talking about the DL and UL data rates.
I’ll upload a revision shortly.
Regards,
Alice

Hi Rui,
Thank you for your response. So, essentially, we don’t need to change the proposed text.
The ON and OFF symbol notations are tied to carrier waveform. For example, see the following from 11ba spec.
That was exactly the reason that we need to use different ON and OFF symbol notations to describe different transmission modes, and refer them back to the waveform generation subclause and mathematical description of signals subclause as in 11ba spec. The discussion is necessary to explain the reason that we changed the MC-OOK ON and OFF symbol notations from using the MCS index (“McsX”) to symbol duration (“Xns”). I think we can revise the first paragraph in the Discussion as what I proposed in an earlier email.
What do you think?
Regards,
Alice

Hi Alice,
Thanks for a quick response.
- For N_SPDB, I am fine to keep it for now. We can decide if it is really needed later.
- For the discussion part, this PDT is on MCS and the description is agnostic to carrier waveform definition? If so, suggest to remove the related discussions, e.g.
“
The carrier waveform for bistatic backscatter communication is TBD. Based on existing proposals, it is likely to be an MC-OOK waveform different from the MC-OOK waveform used for DL transmission to monostatic backscattering non-AP STAs and non-backscattering non-AP STAs, and UL monostatic backscattering transmission.
At this point, for simplicity, we do not differentiate the MC-OOK waveform.For DL transmission and UL monostatic backscattering transmission, there are two different data rateswith the MC-OOK waveform,“
Thanks,
Rui

Dear Rui and other TTT members,
Thank Rui for comments during the presentation.
For your comment #1, what do you think of changing the first paragraph in Discussion to the following?
The carrier waveform for bistatic backscatter communication is MC-OOK, but the exact carrier waveform is TBD.
For your comment #2, I think it’s better to keep the definition of N_SPDB in the Mathematical description of signal. In 11ba, N_SPDB is different for LDR and HDR. In 11bp, it is also different for MCS with BCC and MCS without BCC. And, similar to below spec text in 11ba, expect that this parameter will be used in other subclauses as well.
Regards,
Alice

Dear All,
An updated version (11-25/1964r1) has been uploaded. In r1, based on previous email discussions, the following changes were made.
- Fixed the grammar in two sentences (on BCC) in Amichai's comment #2.
- Added 40.3.8.2.1 as a reference per Yinan's comment.
- Moving Table 40-8 up in an instruction to TGbp editor, per Nelson's comment.
- Added a definition of N_SPDB in 40.3.7.
Please provide additional feedback if any.
Regards,
Alice
