More Information
802.11ax/be utilizes RU (Resource Unit) allocation to implement OFDMA.
AP (Access Point) will send RU allocation signaling (8 bits for each 20 MHz band) to
indicate RU allocation pattern (including RU size and RU position). In order to
demodulate OFDMA signal, it’s required to set Modulation Format
(BPSK/QPSK/16QAM/64QAM/256QAM/1024QAM/4096QAM) and MCS
(Modulation and Coding Schemas, range from 0 to 11).
RU Size
This parameter determines the size of each RU.
This is a list of parameters, and the length of the list is the number of RUs.
Remote Command
[:SENSe]:DEMod[:WLAN]:RU:LIST:SIZE <integer>,<integer>,<integer>,…
[:SENSe]:DEMod[:WLAN]:RU:LIST:SIZE?
Example
:DEM:RU:LIST:SIZE 26,26,26,26,26,26,26,26,26
:DEM:RU:LIST:SIZE?
Notes The length of the list is variable and determined by the number of RUs
