I am using LTE Link Level 1.7_r1089 and I’m trying to understand of working principle of Best CQI scheduling algorithm. I run LTE_sim_batch.m file but there was no CQI_feedback in UE_output part of workspace as you see in Figure below. I used these lines in LTE_load_parameters.m to observe CQI feedback;
you can see the CQIs of the user(s) in simulation_results.UE_specific(user_index).used_CQI
and the number of ressource blocks a user has been assigned to in every subframe (by the scheduler) in simulation_results.UE_specific(user_index).RBs_assigned
where user_index should be replaced by your desired user’s index. For both variables the indexes are interpreted as (subframe_index, SNR_index, transmission_stream).
As a minimum working example just change Simulation_type = 'LTE-A SUMIMO';
to Simulation_type = 'MUSISO';
in LTE_sim_batch.m and run it.
