Hi Ross,

Thank you for the new version. Please see some more comments (in the usual CR format) on revision 01, I just saw you have revision 02, appologies if they are already resolved

Comment	Page No.	Subclause	SFD reference	Proposed Change (if applicable)
"The EHT-SIG field provides the necessary signaling in addition to U-SIG for the STAs to interpretate the EHT PPDU.". EHT-SIG helps both STA and AP to know allocation parameters and not limited to STA. Ross: In IEEE specs, STAs mean both AP STAs and non-AP STAs. So it is fine.	2	34.3.10.7.1
"A 3×996+484-tone RU is referred to by seven RU Allocation subfields per EHT-SIG content channel, for both EHT-SIG content channels. The seven RU Allocation subfields per EHT-SIG content channel are labeled from the first RU Allocation subfield to the seventh RU Allocation subfield". Not very clear Ross: this paragraph is just to follow 11ax. A 3*996+484-tone RU overlaps 14 of 242-tone RU, and hence referred by 14 RU allocation subfields in total (7 per CC). Please see if this has resolved your concern and if you have some better suggestions. In 11ax: A 996-tone RU is referred to by two consecutive RU Allocation subfields per HE-SIG-B content channel, for both HE-SIG-B content channels. The two consecutive RU Allocation subfields per HE-SIG-B content channel are labeled the first RU Allocation subfield and the second RU Allocation subfield. A 484-tone RU is referred to by a single RU Allocation subfield per HE-SIG-B content channel, for both HE-SIG-B content channels. Smaller RUs are referred to by a single RU Allocation subfield in a single HE-SIG-B content channel. If a Common field is present in a 160 MHz or 80+80 MHz PPDU, a 2×996 tone RU is not permitted and cannot be indicated by the RU allocation subfield(#24193).	4	34.3.10.7.3
Image Figure 34-x suggests that common field and user field get separate CRC and tail for all modes, whereas this is not decided yet. For example in the SU case a single shared CRC+Tail for common + user field may be of interest to fit 2 EHT symbols. Ross: added	2	34.3.10.7.2		Add that the organization of CRC+Tail for compression modes is TBD for both common and user fields.
"In an EHT MU PPDU , an RU that is not allocated to a user can be indicated as follows (TBD):" Section is very unclear due to the TBDs. Relevant straw polls in compendium. Ross: Corrected	5	34.3.10.7.3	Straw poll #200	Compendium has more information (SP #200), update accordingly
The RU allocation subfield includes large size of RU aggregation for OFDMA transmission as follows: missing 2x996+484, and 3x996+484 M-RU Ross: added	7	34.3.10.7.3	Motion 115, #SP72, [14] and [30]	add 2x996+484, and 3x996+484
Indicates the number of non-OFDMA users. Set to n to indicate n+1 non-OFDMA users. (Table 34-xx3 Common field for compressed mode) add that this is per RU (as also referenced later in the text) Ross: what do you mean by per RU? Non-OFDMA means only a single RU.	9	34.3.10.7.3

Thanks,

Ron
