Hence definition is not needed for HE MU or HE TB PPDU. The commentor is right that should be defined for HE ER SU PPDU since BEAM_CHANGE value set to 0 does apply to HE ER PPDU.

It is defined under Equation (28-8). 11607 Dorothy Stanley 401.25 In Clause 28.3.4 says: "In the HE TB PPDU, the pre-HE modulated fields, which include L-LTF, L-SIG, and HESIGA fields, are sent only on the 20 MHz channels where the STA's HE modulated fields are located." I don't see how this equation matches this statement for UL MU. There needs to be a per-user component for UL MU. This equation needs to be modeled like Eq 28-4. Best would be to create separate equations for UL MU. as in comment Rejected.

Please provide analysis that not assigning values to tone indices with blank RU's will not degrade correlation performance, as there will effectively be a different sequence/pattern for each combination of blank RU's.

Add a note to emphasis that for 1x/2x LTF, bad smoothness may lead to significant performance loss. Rejected. Smoothing spatial mapping matrices is a recommendation.

I interpret this as HE-LTFs are only transmitted based on the N_STS for the specific RU. I don't believe this is correct, so what is the point of this sentence? as in comment Rejected. This sentence that the transmitter use HELTF as training sequence to facilitate receiver to estimate the MIMO channel for rth RU which can be estimated as an matrix. As for the number of transmitted HE-LTF symbols for each RU is described in the following texts for each type of HE PPDU. I don’t think this sentence alone indicates that are only transmitted based on the N_STS for the specific RU. Dorothy Stanley 436.39 "In an HE TB PPDU, the transmitter of user u in the r-th RU provides training for NSTS,r,u space-time streams used for the transmission of the PSDU."
