I had similar question before. It depends if pilot location is part of tone plan.
In 11ax, Table 27-8 and the figure itself don’t differentiate data and pilot subcarriers.
Section 27.3.12.13 Pilot subcarriers further clarifies.

Hi Ron,
Are we reusing 11ax tone plan for 80MHz/160MHz/80+80MHz non-OFDMA PPDU?
Aren’t pilot locations different?
Best regards,

Candidate SFD text contributions for inclusion to TGbe SFD: Call for Review [REMINDER]
Hi Ross,
Thanks for pointing out, agree.
The TBD subbullet can indeed be removed.
The three old motions below can be amended later e.g.
802.11be reuses 802.11ax tone plan for 20/40/80/160/80+80
MHz PPDU and for 80/160/80+80 in non-OFDMA PPDU
For 320 MHz and 160+160 MHz PPDU,
802.11be uses duplicated HE EHT 160 for OFDMA tone plan.
[Motion 33, [3] and [6]]
802.11be 240/160+80 MHz transmission consists of 3x80 MHz segments
while the tone plan of each 80 MHz segment is the same as HE80 in 802.11ax.
[Motion 35, [3] and [6]]
The 802.11be 320/160+160 MHz non-OFDMA tone plan uses duplicated tone plan of
HE EHT 160.
NOTE – Puncturing design TBD.
[Motion 34, [3] and [6]]
Thanks,
Ron

Hi all,
If SP#42 passed, some existing motions related with tone plan need to be changed accordingly. For example:
802.11be reuses 802.11ax tone plan for 20/40/80/160/80+80 MHz PPDU.
For 320 MHz and 160+160 MHz PPDU,
802.11be uses duplicated HE160 for OFDMA tone plan.
[Motion 33, [3] and [6]]
802.11be 240/160+80 MHz transmission consists of 3x80 MHz segments
while the tone plan of each 80 MHz segment is the same as HE80 in 802.11ax.
[Motion 35, [3] and [6]]
The 802.11be 320/160+160 MHz non-OFDMA tone plan uses duplicated tone plan of
HE160.
NOTE – Puncturing design TBD.
[Motion 34, [3] and [6]]
Straw poll #42
802.11be supports the following toneplan for 11be 80 MHz OFDMA.
·
80 MHz OFDMA = 40 MHz DUP, Table 27-8 in 11ax D6 right/left shifted by 256 tones.
·
Note
o
The 80MHz OFDMA design applies to any RU<996 for all modes of transmission, SU, DL MU, TB PPDU, with and without puncturing
o
Non-OFDMA full BW 80MHz segment uses 996RU design
o
Any punctured 80MHz segment uses the OFDMA tone plan
o
For each 80MHz segment in 160MHz, 240MHz or 320MHz: if it is punctured or used for OFDMA the 80MHz OFDMA tone plan is used, if it’s used for non-OFDMA and non-punctured the 996RU tone plan is used
[#SP42]
[20/0666r2 (80MHz OFDMA Tone Plan, Ron Porat, Broadcom), SP#1, Y/N/A: 44/1/5]
Also, some TBD will be no longer TBD:
A 160 MHz tone plan is duplicated for the non-OFDMA tone plan of 320/160+160 MHz PPDU.
·
The 160 MHz tone plan is
TBD.
[Motion 18, [3] and [7]]

Hello all,
Our TGbe Editor has prepared the Rev 26 of the compendium of SPs and potential changes to the SFD, which can be found below:
This is a call for members to review the new SFD text contributions (which are highlighted in yellow and identified by tags listed as [DCN (Presentation, Author, Affiliation), ...] SP#X, ...) in the compenidum of SPs document.
Please do send an e-mail in response to this Call For Review if you would like to identify any of these "new SFD text contributions" as contributions that need further discussion. The deadline for sending these e-mails is June 10th 2020 @10:00am ET.
A list of these requested contributions will be queued for discussion and run as a separate motion (Motions >=113) during the Joint conference call scheduled on June 11th 2020.
New SFD text contributions that have not received a request for further discussions will be part of the cumulative motion (Motion 112) that will be run at the same Joint conference call.
Please refer to the document linked below for a list of the motions:
For more information please refer to the subclause "Guideline-Building Consensus and Populating the TGbe SFD" in the TGbe teleconference agendas: https://mentor.ieee.org/802.11/dcn/20/11-20-0735-15-00be-2020-mar-may-tgbe-teleconference-agendas.docx.
If you have any comments and/or questions please let me know.
Best Regards,
Alfred
