Can the NumSpaceTimeStreams in wlanHESUConfig be larger than 8?

I'm doing the simulation about downlink MU-MIMO. I reference the example 'HEDownlinkMUExample' and trying to get the simulation results with 12 transmit antennas.

However, 'wlanHESUConfig' has the rule that 'NumSpaceTimeStreams' must be an integer in [1,8], 12 is out of the bound.

How to solve this problem?

what else should I reference if I want to do Downlink MU-MIMO simulation with 12transmit antennas for 1 AP and 1 receive antennas for each 6 users on the link-level?

Hi Yanxi,

I understand that you would like to simulate downlink MU-MIMO where number of transmit antennas of Access Point (AP) is equal to 12. Currently, MU-MIMO in MATLAB is supported for number of space time streams less than or equal to 8. There aren't any alternatives to simulate downlink MU-MIMO with 12 antennas.

'wlanHESUConfig' is a configuration object for the WLAN HE single-user (HE SU) and HE extended-range single-user (HE ER SU) packet formats and not for MU-MIMO configuration. 'wlanHEMUConfig' is the configuration object used for defining MU-MIMO configuration. Kindly refer to the below example to understand throughput simulation of MU-MIMO with downlink OFDMA.
