These bullet points for HE mirror the e) and f) for VHT, where the 20 MHz VHT mask is used. For example bullet i) is already covered by b) unless the spectrum mask is not the same. Same for 40 MHz, 80 MHz ... In each bullet point from h) to k), refer to "the 20 MHz transmit spectral mask defined in Clause 28 (High Efficiency (HE) PHY specification)", e.g. replace "A Clause 17 PPDU transmitted by an HE STA using the transmit spectral mask defined in Clause 19 (High Throughput (HT) PHY specification)." with "A Clause 17 PPDU transmitted by an HE STA using the 20 MHz transmit spectral mask defined in Clause 28 (High Efficiency (HE) PHY specification)." and so on Check consistency with 40 MHz, 80 MHz ... and apply the same change if needed.

See comment Revised. 11ax editor, please see the discussion for instructions of CID 13500 in doc IEEE 802.11-18/0475r0. 13765 485 38 "The bandwidth of the spectral mask applied to an HE SU PPDU, an HE TB PPDU and an HE MU PPDU with the Bandwidth subfield of the HE-SIG-A field equal to 0, 1, 2 or 3 shall be determined by the bandwidth indicated in the Bandwidth subfield of the HE-SIG-A field." If 20MHz only STA is multiplex with 80MHz capable STAs via OFDMA in MU PPDU and TB PPDU, the mask of 20MHz only STA should still be 20MHz instead of the BW indicated in HE-SIG-A. Add the following sentence before the last sentence of P.L. 485.46. "The bandwidth of the spectral mask applied to an 20MHz only STA shall be 20MHz regardless of the Bandwidth field indicated in in the MU PPDU or TB PPDU" Revised. The commen is valid and need to be calrified. 11ax editor, please see the discussion for instructions of CIDs 13765, 14202, 14203, 14204 and 14205 in doc IEEE 14088 491 11 Transceivers for HE160/80+80 MHz PPDUs may use two RF LOs, one for each 80 MHz portions. Add to the end of 28.3.18.3: "Transmit signals with TXVECTOR parameter CH_BANDWIDTH set to CBW160 or CBW80+80 may be generated using two separate RF LOs, one for each of the lower and upper 80 MHz frequency portions. NOTE--The signal phase of the two 80 MHz frequency portions might not be correlated."

However the EVM measurement method is not updated accordingly in 28.3.18.4.4 Transmitter modulation accuracy (EVM) test. Specifically, EVM test only requests 16 OFDM symbol for user occupies more than 26 tones. Good long packet EVM performance is essential for good throughput. We need to increase the number of OFDM symbol for EVM test. Please evaluate and suggested a reasonable long packets for EVM test, which eventually will guarantee a good throughput in real operation. Maybe we should use 32 OFDM for all cases, which will at least include one midamble. Or if chipset companies has a more practical number that will review system performance in long packets. Rejected. Midamble is an optional feature and it is not essential to the EVM tests. In the 11ax spec, the following sentence is added to exclude the EVM tests with midamble. Discussions for CID 11897:
