This introduction is not part of the adopted material. Editing instructions formatted like this are intended to be copied into the TGax Draft (i.e. they are instructions to the 802.11 editor on how to merge the text with the baseline documents). TGax Editor: Editing instructions preceded by “TGax Editor” are instructions to the TGax editor to modify existing material in the TGax draft. As a result of adopting the changes, the TGax editor will execute the instructions rather than copy them to the TGax Draft.

Add the spectral flatness requirement for HE PPDU. TGax Editor: make changes as in 26.3.13.4
The requirements for AP and non-AP STA should be different. Also, regarding non-AP STA transmit specification, requirements for (1) transmission, (2) OFDMA transmission, and (3) UL MU-MIMO transmission could be different. Transmit specification for all of these cases should be specified. (a) spec for AP STA, IBSS STA, and mesh STA. (b) spec for non-AP STA in an HE infrastructure BSS applied to non-MU transmission (c) spec for non-AP STA in an HE infrastructure BSS applied to OFDMA transmission (d) spec for non-AP STA in an HE infrastructure BSS applied to transmission. 2. define Transmit center frequency and symbol clock frequency tolerance for each cases above. defined, class A and class B. Different class STAs have different requirements. See PHY motion 120. However, the different class STAs differ in measurement accuracy and transmit power accuracy. Whether TGax requires four different tolerance values should be subject to discussion and requires an IEEE contribution. It is clarified that additional requirement for trigger-based PPDU is defined in 26.3.14 (Transmit requirements for an HE PPDU) TGax Editor: make changes as in 1115 Koichi Ishihara 26.3.13.1 158 3 Transmit spectral masks at each bandwidth are not mentioned in the current draft although these are defined in SFD.
