Using Compressed Mode with SU/MU-MIMO for EHT MU PPDU

Versions ≤ 3.0 of the N7617C software could not support MU-MIMO and had issues with SU-MIMO for compressed mode. Now, with version 4.0, it can generate MIMO waveforms for single-user or multiple-users.

1. Select IEEE 802.11be MxN from the Quick Setups node.

2. Set Number of Transmit Chains (Ntx) to > 1

3. For MU-MIMO, set Number of Full BW MU-MIMO Users to > 1

   

   Set the 6-bit Spatial Configuration subfield under the RU node, which indicates the number of spatial streams for each user and the total number of spatial streams.

   

   For Spatial Configuration, refer to Table 36-42 – Spatial Configuration subfield encoding of specification IEEE P802.11be/D1.0. (See below.)

   

4. For SU-MIMO, set Number of Full BW MU-MIMO Users to 1. And set Number of Spatial Streams (Nss,u) to > 1.

   

5. Generate waveform for multiple antenna ports.
