233 7.1.3.5a 5 27 TR Why have a VHT bit when a transmission is either VHT or HT as indicated by the SIGNAL field in the PHY preamble? Suggest removing this redundant bit. After auto-detection the information about whether the frame is HT or VHT may be passed through RXVECTOR from PHY to MAC. Also Change "Figure frame format" accordingly. Suggest removing this redundant HT/VHT bit. Change "Figure frame format" showing HT/VHT control field. Insert text indicating "HT/VHT control field is a HT control field or a VHT control field depending on whether the MPDU is a HT MPDU or VHT MPDU respectively." Reject the removal of B0; The bit B0 is needed in case of control wrapper. Control wrapper can be sent with non-HT in which case B0 defines the type of the field. Discussion on whether the VHTC can be in HT PPDU and vice versa; MAC Comments referred to capability indications
