Hi Rui, My understanding is it follows 11ac/11ax. So it can be used when spectrum is non-contiguous (160Mhzin 5.2GHz, 80MHz in 5.8GHz for example). At least I’d like to reflect what is written in the SFD: 802.11be supports 320 MHz and 160+160 MHz PPDU.

Hi Ross, The motion text “160+160MHz” is unclear whether “160+160 MHz noncontiguous” is included. “160+160 MHz” means two LOs with each LO corresponds to 160MHz signal bandwidth. The motion didn’t specify how far apart the two LOs can be. Understand that some
people may refer to 11ac/11ax for the interpretation. But we need further SP/motion to clarify that for 11be. My understanding, the current text in 1307r0 about “160+160MHz noncontiguous TBD” is accurate. Thanks, Rui From: Yujian (Ross Yu) <ross.yujian@xxxxxxxxxx>
Hi Bin, In the text, it mentions:
The EHT PHY provides support for 20 MHz, 40 MHz, 80 MHz, 160 MHz and 320MHz contiguous channel widths
(note: support for 80+80 MHz and 160 +160 MHz noncontiguous channel width is TBD), depending on the frequency band and capability. Whilst in 566r66, we have the following motions: 802.11be supports 320 MHz and 160+160 MHz PPDU. [Motion 10, [3] and [4]] 802.11be reuses 802.11ax tone plan for 20/40 MHz PPDU and, with the exception of pilot locations, for 80/160/80+80 MHz in non-OFDMA PPDU.
For 320 MHz and 160+160 MHz PPDU, 802.11be uses duplicated EHT160. [Motion 33, [7] and [13]] [Motion 118, [14] and [15]] 802.11be reuses the phase rotation sequence defined in 802.11ax for 20/40/80/160/80+80 MHz PPDU.
[Motion 112, #SP31, [17] and [45]] From PHY support perspective, it is not TBD. regards 于健 Ross Yu Huawei Technologies 发件人: Bin Tian [mailto:btian@xxxxxxxxxxxxxxxx]
Hi TTT members and all I have uploaded the 20/1307r0 Introduction to EHT PHY. Please review it and let me know if you have any feedback.
