    Dear Sir,
    I have run the LTE UL LL v1.3 r719 for 1.4 MHz for 30 Users and PF schedulers and .2 HTTp and 40% VOIP and 40% video.for 1000 TTI and gives me following users throughput for CQI = 1:15.
    Throughput =

    Columns 1 through 11

    4.4298 4.4260 4.4188 4.4144 4.4239 4.4156 4.4229 4.4291 4.4273 4.4214 4.4150

    Columns 12 through 22

    4.4325 4.4225 4.4195 4.4326 4.4233 4.4156 4.4275 4.4329 4.4231 4.4182 4.4149

    Columns 23 through 30

    4.4255 4.4196 4.4255 4.4116 4.4363 4.4318 4.4232 4.4177

    ans =

    132.6980
    By the way the 1.4 MHz UL LTE should be 60 MBPS.

    Hi,

    as I already said, the traffic models are not properly implemented in the link level uplink simulator. Further, I am not sure which simulation results you are showing me here. You simulate over 15 fixed CQI values for 30 values of SNR? Is this the sum troughput?

    I advise you to run a simulation with only two users, no traffic models and the PF scheduler to see if this scheduling algorithm behaves the way you admire.

    best

    Hi,

    30 users for SNR = 0:40 db, and cqi = 1:15. Scheduling scheme is PF. and the sum of users throughput is = 132.698 MBPS.
    I can use System level simulator for BandWidth Allocation in Uplink LTE.
