    Dear all,

    Is there an example for configuring MLaner user traffic model. I am using the following settings:
    %% Scheduler options
    LTE_config.scheduler = ‘constrained’; % ’round robin’, ‘best cqi’, ‘max min’, ‘max TP’, ‘resource fair’, or ‘prop fair Sun’
    % LTE_config.scheduler_params.fairness = 0.5; % fairness for the variable fairness scheduler
    % % LTE_config.scheduler_params.alpha = 1; % Additional configuration parameters for the scheduler
    % % LTE_config.scheduler_params.beta = 1;
    % LTE_config.scheduler_params.av_window = 25; % Number of TTIs used to calculate the average throughput (exponential filtering)
    % % See: P. Viswanath, D. Tse and R.
    % % Laroia, “Opportunistic Beamforming using Dumb Antennas”, IEEE Transactions on Information Theory, vol. 48(6), June, 2002.
    % LTE_config.power_allocation = ‘homogeneous;’; % ‘right now no power loading is implemented, so just leave it as ‘homogeneous’
    %%Traffic
    LTE_config.traffic_models.usetraffic_model = true;
    LTE_config.traffic_models.type = ‘MLaner’
    LTE_config.traffic_models.av_cell_TP = 30;
    LTE_config.traffic_models.user_distribution = true;

    Best,
    D

    Dear David,

    You can consider the launcher file in sim_main_launcher_files/LTE_sim_main_launcher_demo_trafficmodels.m and modify it with the parameters you have listed

    LTE_config.traffic_models.usetraffic_model = true;
    LTE_config.traffic_models.type = ‘MLaner’
    LTE_config.traffic_models.av_cell_TP = 30;
    LTE_config.traffic_models.user_distribution = true;

    and

    LTE_config.scheduler = ‘prop fair traffic’; % or ’round robin traffic’

    Note that when using traffic models, only specific schedulers have to be used, one of the two types above.

    Best regards,
    Fjolla
