TGax Editor: Please make the following text change (changed texts are in red) in the line 1, page 494 of D2.0: is the number of data tones of the occupied RU; For the 80+80MHz transmissions, is the total number of data tones NSD NSD of both 80MHz frequency segments. Please also remove the text in the line 6-7, page 494 of D2.0 NOTE 1—In the case the transmit modulation accuracy test is performed simultaneously for the two frequency segments of the 80+80 MHz transmissions with RU. Discussions for CID 11406: TGax Editor: Please make the following text change (changed texts are in red) in the line 39-40, page 492 of D2.0: NOTE—For 1024-QAM, relative constellation error shall be equal to or less than -35 dB when amplitude drift compensation in the test equipment is on and shall be equal to or less than -32 dB when amplitude drift compensation is off in the test equipment. Relative constellation error equal or less than -35dB when amplitude drift compensation is off in the test equipment meets the relative constellation error requirement for 1024-QAM as well. For all other constellations the EVM shall be equal to or less than the values in the table, no matter whether amplitude drift compensation in the test equipment is on or off. Discussions for CID TGax Editor: Please make the following text change (changed texts are in red) for the first paragraph in section 28.3.18.4.3 of D2.0: The relative constellation RMS error in the test, calculated by first averaging over subcarriers, frequency segments, HE PPDUs, and spatial streams (see Equation (28-120)) as described in 28.3.18.4.4 shall not exceed a data-rate dependent value according to Table 28-45 (Allowed relative constellation error versus constellation size and coding rate). The number of spatial streams under test shall be equal to the number of utilized transmitting STA antenna (output) ports and also equal to the number of utilized testing instrumentation input ports. In the test, = (no STBC) and no beamforming steering matrix shall NSS NSTS be used.
