    Hi everyone,

    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;

    switch LTE_params.Bandwidth
    case 1.4*10^6 = true;
    LTE_params.UE_config.PMI_fb_granularity = 6;
    LTE_params.UE_config.CQI_fb_granularity = 6;
    LTE_params.UE_config.CQI_fb = true;


    Actually I couldn’t see any command about CQI feedback in bestCqiSchedulerMMO.m file. How can I find CQI feedback from UEs in this simulator?

    I am looking forward for your reply.
    Best regards,

    Dear Önem,
    you can see the CQIs of the user(s) in
    and the number of ressource blocks a user has been assigned to in every subframe (by the scheduler) in
    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';
    Simulation_type = 'MUSISO';
    in LTE_sim_batch.m and run it.

    Best regards,
