    Default Atoll UL prediction

    Hi all,
    I'm trying to do an UL prediction for LTE. Do you have any idea what settings can be used?
    I have a very large are with 64QAM modulation, maybe because the CINR is very good in this area (10km) ~17 but I don't know why.
    I used default settings for proportional fair scheduling :

    Name Scheduling Method Target Throughput for Voice Services Target Throughput for Data Services Bearer Selection Criterion Uplink Bandwidth Allocation Target
    Proportional Fair 0 - Proportional Fair 0 - Peak RLC Throughput 0 - Peak RLC Throughput 0 - Bearer Index 2 - Best Bearer
    I tried also with and without UL power adjustment.
    Any suggestion will be appreciated.
    BR

    The Throughput in the UL channel depends on the load and interference from subscribers from neighboring cells. See what's in the LTE Cells table in column Traffic Load UL (%), UL Noise Rise (dB). Usually, if there are statistics on busy hour PRBS Load, they are added to the LTE Cells table. Or the load can be obtained after Monte Carlo simulations

    Hi Dimitry, you have right. Do you have any idea about UL Noise Rise value?
    I used 30% traffic load. The default scheduling values are ok?
