B17-B18 Coding 2 B17 set to 0 for BCC and 1 for LDPC If B17 is 1, B18 is set to 1 if the LDPC PPDU encoding process (of an SU PPDU), results in an extra OFDM symbol (or symbols) as described in 22.3.10.5.4 (LDPC coding), otherwise set to 0. If B17 is 0, B18 is reserved and set to 1. B19-B22 MCS 4 MCS Index B23 Smoothing 1 A value of 1 indicates that channel smoothing is recommended. A of 0 indicates that channel smoothing is not recommended. B0 Aggregation 1 Set to 1 when aggregation is ON (A-MPDU), and 0 otherwise. Note: S1G PPDUs shall be transmitted with aggregation ON whenever PHY payload size is greater than 511 octets B1-B9 Length 9 Denotes the length of PPDU in number of symbols when aggregation bit is set to 1, and in number of octets when aggregation bit is set to 0. B10-B11 Response 2 This field indicates the presence and type of frame a Indication SIFS after the current frame transmission. Set to 0 if No Response. Set to 1 if NDP Response. Set to 2 if Normal Response. Set to 3 if Long Response. SIG-2 B12 Doppler 1 Set to 1 to indicate traveling pilots usage in packet. Otherwise 0 to indicate regular pilot tone locations. B13 NDP 1 Used to indicate that frame is a Control NDP frame. If Indication set to 1, then the SIG field contents follow the description in 8.3.5 (NDP MAC frames) B14-B17 CRC 4 CRC calculated as in 24.3.8.2.1.5 (CRC calculation for S1G SIGA fields). B18-B23 Tail 6 Used to terminate the trellis of the convolutional decoder. Set to 0. .
