    hi
    i’m new to LTE-A-DL-System-Level-Simulator, i use Rel-v1-9-Q2-2016.
    My question is about CoMP Categories, where can i find the parameters for changing between CoMP Joint Transmission (JT) and CoMP Coordinated Beamforming (CBF) to do a camparison between the two techniques ?
    thank you

    Dear,

    Our implementation of CoMP is only about scheduling, where we provide one example under configuration LTE_config.CoMP_configuration=’global’. In this case all eNodeBs are in the same site and potentially all are cooperating. If you want to include beamforming, then add LTE_config.support_beamforming = 1; in the launcher file.

    Best regards,
    Fjolla

    Dear Fjolla Ademaj,

    channel = ruleset.own_channel(:,:,2*rb_);
    Error in CoMP.schedulers.roundRobinCB/schedule_users (line 64)
    [for_pmi, for_ri] = obj.find_forbidden(next_ue,
    rb_, feedback, i_);
    Error in CoMP.schedulers.CoMP_scheduler/fetch_grid (line 35)
    obj.schedule_users(eNodeB,attached_UEs,last_received_feedbacks);

    Error in schedulers.CoMP/schedule_users (line 45)
    UE_id_list =

    Error in network_elements.eNodeB_sector/schedule_users (line 259)
    obj.scheduler.schedule_users(obj.attached_UEs_vector,obj.last_received_feedback);

    Error in LTE_sim_main (line 442)
    eNodeBs(s_).schedule_users;
    Error in LTE_sim_main_launcher_demo_CoMP (line 60)
