Hi Jason
Thanks for the update.
I have one comment on the special user info field. The specification already defined a mapping from B25-B36 of the special user info field to the B20-B25(BSS color 2 subfield) in U-SIG1 and B2
(CoBF/CoSR indication), B11-B15(number of UHR-SIG symbols field) in U-SIG2 for both EHT and UHR TB PPDU. We can easily extend this mapping to support DL non-OFDMA Co-BF transmission and DL SU Co-SR transmission as Length, GI/LTF size and TX power field, which
is reused to support DL non-OFDMA Co-BF transmission and DL SU Co-SR transmission. This would help to make the spec cleaner and more consistent.
Thanks,
Juan
