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. regards 于健 Ross Yu Huawei Technologies 发件人: Wook Bong Lee [mailto:wookbong.lee@xxxxxxxxxxx]
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 From: Ron Porat [mailto:000009a0da80e877-dmarc-request@xxxxxxxxxxxxxxxxx]
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 From: Yujian (Ross Yu) [mailto:ross.yujian@xxxxxxxxxx]
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]] regards 于健 Ross Yu Huawei Technologies 发件人: Alfred Asterjadhi [mailto:asterjadhi@xxxxxxxxx]
