Hi,
– yes it does change the QAM based on an SNR-to-CQI mapping, which is stored in a look-up table [obtained from link-level simulations] and loaded at the beginning of the simulation.
– In order to safe simulation time, we have implemented the option simulate_only_center_users. this option might be set true in your setup. All users shown in red have not been simulated.
Best regards,
Martin.
