Calculate HE or WUR PSDU length
Get the PSDU length of HE single-user (HE SU) and HE multi-user (HE MU) configuration objects.
Get HE SU PSDU Length
Create an HE SU configuration object. Get and display the PSDU length for the configured transmission.
cfgHESU = wlanHESUConfig; psduLength = getPSDULength(cfgHESU)
psduLength = 100
Get HE MU PSDU Lengths
Create an HE MU configuration object with the allocation index set to
5, which configures a transmission with seven users. Get and display the PSDU lengths for the configured transmission.
cfgHEMU = wlanHEMUConfig(5); psduLength = getPSDULength(cfgHEMU)
psduLength = 1×7 100 100 202 100 100 100 202
Create a wake-up radio (WUR) configuration object for a transmission with four subchannels and four transmit antennas.
cfgWUR = wlanWURConfig(4,NumTransmitAntennas=4);
Calculate the PSDU lengths for the transmission and display the result.
psduLength = getPSDULength(cfgWUR)
psduLength = 1×4 8 8 8 8
cfg— HE or WUR transmission parameters
psduLength— PSDU length
PSDU length, in bytes, returned as a positive integer or row vector of size 1-by-N, where N is the number of users in the transmission. For an HE transmission, N is an integer in the interval [1, 74]. For WUR transmissions, N is 1, 2, 3, or 4.
For more information about N in HE transmissions, see the
NumUsers field of the
output corresponds to N.
