Reasons as above 11601 Dorothy Stanley 400.40 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 Revised. Change to as in the resolution of CID11601 in doc 11602 Dorothy Stanley 400.40 its not clear in an HE TB PPDU for a user with an RU <=242 in a 40, 80, or 160/80+80MHz bandwidth, whether L-STF is transmitted in the user's 20 MHz or the entire PPDU BW. Something in this as in comment Rejected. In Clause 28.3.4 , it states that "In the HE TB PPDU, the pre-HE modulated fields, which include L-STF, L-SIG, RL-SIG and HESIGA
equation needs to be indexed on a per-user basis, perhaps i_BW or Omega_20MHz? fields, are sent only on the 20 MHz channels where the STA's HE modulated fields are located."
