I think this is a bit backwards, even if of course the number of non-zero sub-carriers is 64 minus the number of null sub-carriers.

Thanks Leif/Bin/Alfred for the suggestion during the call.
After checking 11mf, I notice that the phrases of “non-zero” and “loaded/populated” are not used for IFFT, and only “null” is used. I am proposing to make the following changes to the sentence:
- “The base OFDM symbol is generated by performing
a 64-point IFFT
of with TBD
non-zero
null tones
subcarriers and pre-appending the last 0.8us waveform as the cyclic
prefix.”
Let me know if you have other suggestions to the wording.
Thanks,
Rui

Hi Leif,
Thanks for the information. I will make the change to 2.4GHz text as suggested.
For S1G, looks like there are different interpretations of the motion text.
@lipanpan
(D), do you want to bring another SP/motion to clarify your intention? or I can leave out S1G waveform text for now.
Thanks,
Rui

Hi Rui,
The way I recall the discussion related to motion #94 is that it originally said CW, but when Joerg asked if the intention really was to have a carrier wave the answer was that the intention was to say that it should be single carrier
(and not OFDM), and therefore the SP was changed to single carrier.
I believe the spec text therefore should read as the passed motion.
A minor editorial thing. In 40.3.3.1, I suggest writing
. The base OFDM symbol is generated by performing 64-point IFFT of TBD
non-zero tones
Instead of
The base OFDM symbol is generated by performing 64-point IFFT of TBD
loaded tones
BR,
Leif
Hi Bo,
Please help to add the following PDT to the agenda:
Hi TTT members,
After confirming with the motion mover for the S1G carrier definition, I keep the CW definition in the PDT. Please review if you have any comments or suggestions.
Thanks,
Rui
