This topic applies to the following Generation Mode:
EHT MU PPDU
Select the Symbol interval (with guard interval) for the EHT-LTF field.The current combinations are 2x EHT-LTF + 0.8 us, 2x EHT-LTF + 1.6 us , 4x EHT-LTF + 3.2 us and 4x EHT-LTF + 0.8 us.
Specify the number of EHT-LTFs. If Maximum Number of Total Space Time Streams is 1, then its value is 1, otherwise its value is the ceiling of (NumOfTotalSpaceTimeStreams / 2.0) * 2.
Get the maximum Number of Total Spatial Streams in all Resource Units.
Set the number of transmit chains. When the number of instruments is more than 1 and the Channel State is Off, it automatically equals to the number of instruments and can't be changed, otherwise, it's editable.
Get the Pre-FEC Padding Factor.
Set or Get the Maximum Packet Extension Duration for Current PPDU.An EHT PPDU may have a Packet Extension (PE) field appended at the end of the PPDU, with possible durations being 0us,8 us or 16 us. The PE field, when present, shall be transmitted with the same average power as the Data field, and its content is arbitrary.
Indicates whether the frame is Uplink or Downlink. The field is set to DL for TDLS and set to UL for EHT TB PPDU.
Get or Set the Base station identifier.The BSS Color field is an identifier of the BSS.
Range:
80 MHz bandwidth: 0 to 4
160 MHz bandwidth: 0 to 12
320 MHz bandwidth: 0 to 24
Get or set the value of punctured channel pattern for non-OFDMA.
See also, 802.11be Concepts.
Indication of the punctured channel pattern for non-OFDMA.
Each character represents 20 MHz for the 80M/160M bandwidth, and 40 MHz for the 320 bandiwdth. 'x' means punctured and '1' means not.
See also, 802.11be Concepts.
Set or Get the remaining time duration in the current TXOP. Set to 8449 μs to indicate no duration information. Set to value other than 8449 μs to indicate the duration information for NAV setting and protection of the TXOP. When the value ranges from 0 to 504 μs, the granularity is 8 μs. When the value ranges from 512 to 8448 μs, the granularity is 128 μs.
Choices: On | Off
Default: On
Coupling: The RU Arrangement Settings are not activated when it is on, and the Number of Full BW MU-MIMO Users is not activated when it is off
This compression bit is carried in the U-SIG to differentiate non-OFDMA from OFDMA PPDU. When enabled it indicate non-OFDMA PPDU.
Set the number of EHT-SIG symbols. Its minimum value is 1 and default value is 2.
Enable/disable Dual Carrier Modulation for payload. It is enabled only for MCS0.
Select the MCS Index of EHT-SIG. Only MCS0, MCS1, MCS3 are supported.
Range: 1 to 8
Default: 1
Coupling: The number of users should not larger than Number of Transmit Chains (Ntx); The Spatial Configuration under RU node is not activated when number of users is 1
Get or set the number of MU-MIMO users when compression mode is enabled.
Range: 000000000 to 111111111
Default: 000011001
Coupling: It defines the combination of small RUs/MRUs, or defines the large RU/MRU and the allocated number of users in it
Gets or sets the RU allocation index for the 1st 2-MHz subband. It may contain multiple small-size RUs/MRUs or a large-size RU/MRU that may span multiple 2-MHz subbands including the current subband.
The index for each Resource Unit of current resource unit allocation per 20 MHz .
