Dong, Rojan, and Zinan,
Thanks for the feedback. I switched toe the Alternative notation for Table B, and I added the reference to “k” as Zinan suggested.
I think this version looks good and I plan to post on Mentor later today.
Zinan,
To your question below, the number 1.5 comes from 12/8, since the scaling factor is 12 bits.
Regards,
Steve

Hi Steve et al,
If Alternative notation is chosen, the meaning of “k” may need to be added in meaning of Table B
Steve, I have one question on Equation (E)
- Does 1.5 in equation E come from
scaling factor/8? If it is the case, do you think it is clearer to indicate as Scaling Factor/8? It is more general and consistent with other expressions, N_TX, N_RX, N_b and N_sc which symbols.
Thanks,
Zinan

Dong, et. al.,
Based on your comment I would like to ask you and others which of the following two notations do you prefer for Table B. Here is the Current Notation for a
few rows and an Alternative notation for those rows.
What is people’s preference?

Steve

Dong,
That is an interesting suggestion. If we did that maybe, we would do the same with the CSI. We can then use the notation from the equations.
If we did it that way we would make the following changes,
- Change “Scaling Factor(TX = 1, RX = 3)” to “
” - Similarly for the CSI we would change “CSI(TX=1, RX=3)” to “
”
Do people prefer this notation for that table?
Regards,
Steve

Hi Steve,
I have a comment on Table B. For example, in the fifth row and first column,
,
“RX” is used as a variable/index and as an abbreviation for receiver simultaneously. I would like to suggest that
Scaling Factor (
)
be replaced with Scaling Factor (
)
or 
,
and similar replacement for all entries in the first column.
Thanks,
Dong

Junghoon, Zinan, and Rui, et. al.,
Thanks Zinan and Junghoon.
I first accepted the changes we have been making to the document and posted that as R3.
I then made the following changes,
- Generated a draft R4 document
- Added Zinan as a co-author
- Made the changes suggested by Zinan (using Track changes)
- Edited Equation (A)
- Edited the sentence after Equation (A) to fit with the edits to the equation
- Added a sentence in b) describing how
may be used in the selection of the scaling factor 
,
which I hope addresses the comment that Rui made.
Hopefully, these address the comment from the call this morning. If this looks good, I can post this as R4. Or if other edits are needed, I can make
those changes and post the edited version as R4.
Regards,
Steve

Hi, Zinan
I am ok with this version as well. It is more clearly described.
I just wanted to mean two bits are not necessary to indicate the I_ng parameter, unless we want to keep one more bits for the forward compatibility like for the
next generation Sensing.

Hi Steve,
Thank you very much for presenting 11-22/1020r2.
Attached please find my suggestions on Table A, which also incorporates Junghoon’s suggestion to put NOTE in the column of Ing meaning.
Please take a look at the document.
