    Dear Fjolla,

    Does FFR support trace version V2 ?

    as When running FFR in tracing version V2, the following error appear:

    TTI 1/10: *****+++++Index exceeds matrix dimensions.

    Error in network_elements.UE/link_performance_model (line 1300)
    [TB_SINR_dB(cw_)] =
    obj.SINR_averager.average(SINR_dB(layers_cw,:),TB_CQI(cw_),true);

    Error in LTE_sim_main (line 479)
    UEs(u_).link_performance_model;

    Hi Naser,

    I have the same problem when running with V2.

    I want to share another point. Can we examine the REUSE-1 by the Vienna simulator.

    FFR parameters are fixed as follows:

    LTE_config.FFR_params.beta_FR = 1;
    LTE_config.FFR_params.SINR_threshold_value = -2;
    (a minimum SINR threshold point)

    I got the errors:

    TTI 1/50: +++++*****Operands to the || and && operators must be convertible to logical scalar values.

    Error in network_elements.UE/set_SINRs_according_to_schedule (line 568)
    if DL_signaling.num_assigned_RBs>0 && ~obj.deactivate_UE

    Error in LTE_sim_main (line 466)
    UEs(u_).set_SINRs_according_to_schedule

    Dear Naser and Nakrop,

    Unfortunately the FFR is not supported with trace version v2.

    Regrading reuse-1, yes this is possible when setting LTE_config.FFR_params.beta_FR = 1.

    There was a bug when using FFR with reuse-1. Now it is fixed and you can download the updated version of the simulator.

    Best regards,
    Fjolla
