Definition at line 71 of file IEEE802_11_PhyFrame.h.

◆ bNot_Sounding

int stru_802_11_HT_PLCP_Frame::bNot_Sounding

1 bit Set to 0 indicates that PPDU is a sounding PPDU. Set to 1 indicates that the PPDU is not a sounding PPDU.

Definition at line 63 of file IEEE802_11_PhyFrame.h.

◆ bReserved

1 bit Set to 1 to indicate that the short GI is used after the HT training. Set to 0 otherwise.

Definition at line 72 of file IEEE802_11_PhyFrame.h.

◆ bSmoothing

int stru_802_11_HT_PLCP_Frame::bSmoothing

1 bit Set to 1 indicates that channel estimate smoothing is recommended. Set to 0 indicates that only per-carrier independent (unsmoothed) channel estimate is recommended. See 20.3.11.10.1.
