    Hello,
    I want to run the simulator to get fixed CQI graph using just PMI feedback, so I set the paramters in LTE_load_parameters.m bellow:

    BW_vect = 1.4e6;
    LTE_params.ChanMod_config.type = ‘VehA’;
    LTE_params.UE_config.mode = 2;
    LTE_params.UE_config.nRX = 1;
    LTE_params.BS_config.nTx = 2;
    LTE_params.UE_config.feedback = false;
    LTE_params.UE_config.PMI_fb = true;
    LTE_params.UE_config.RIandPMI_fb = false;
    LTE_params.UE_config.CQI_fb = false;

    However, I already set LTE_params.UE_config.feedback = false, so PMI feedback calculation didn’t work.
    Do I have to change setting LTE_params.UE_config.feedback = true for PMI feedback?

    Dear Hyunjee,

    I suggest to use

    LTE_params.UE_config.feedback = true;
    LTE_params.UE_config.PMI_fb = true; 
    LTE_params.UE_config.RIandPMI_fb = false;
    LTE_params.UE_config.CQI_fb = false;

    best
    Stefan

    LTE_params.UE_config.mode = 2; is Alamouti coding –> no PMI feedback is required for Alamouti coding –> use LTE_params.UE_config.mode = 4; which is CLSM
