Hi Wookbong and Ross,
Thanks for the comment and clarification, indeed I was debating this issue myself but I think the pilot issue we SP is not part of this motion group so thought we could fix it later.
If we want to be super accurate can write it:
802.11be reuses 802.11ax tone plan for 20/40
Thanks, Ron

Thanks Ross.
If it is clear, then it should be fine.
BTW, thanks for this.
Best regards, Wook Bong Lee

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, Wook Bong Lee

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
For 320 MHz and 160+160 MHz PPDU, 802.11be uses duplicated [Motion 33, [3] and [6]]
802.11be 240/160+80 MHz transmission consists of 3x80 MHz segments [Motion 35, [3] and [6]]
The 802.11be 320/160+160 MHz non-OFDMA tone plan uses duplicated tone plan of 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]]
