    Dear all,

    I want to adjust (blank or reduce) the power of each frames(TTIs) in the traffic one by one
    where I can find this parameter?

    Thank you in advanced.

    Hi Nonthapat,

    in the function lteScheduler.m, you can find the property RB_grid. There, the user allocation and power allocation vector is stored. If you want to change the assigned power, you need to adjust the values that are being written in this vector.

    Best regards,

    I found RB_Grid in the property of lteScheduler.m and I also going into RB_Grid
    It appear a downlinkChannelModel.m and I tried to find the power allocation vector but I still didn’t get it
    can you guide me whereit is?

    Best Regards and thank you in advance,

    Hi Nonthapat,

    after the scheduling is done (LTE_sim_main.m: eNodeBs(s_).schedule_users;), please check the property eNodeBs(s_).RB_grid.power_allocation. You will that, e.g., when using a round robin scheduler, the power allocation is done homogeneously over all RBs (and layers) (see lteScheduler.m, schedule_users_common). If you want to do anything else than homogeneous power allocation, you will have to adapt it there.

    Best regards,
    Martin
