    in E// and if you have WCDMA network,
    - Tune your parameter Coverage-Triggered WCDMA IRAT Handover, make more aggressive HO to WCMA
    - Set up IRAT Offload to WCMA, and Optimize the parameter .
    - see counter pmPdcchCceAggregationDistr, if vector [3] CCE8 is high, it's indicated ue distribution using CCE8 which mean use PRB more. Try to optimize coverage(ex: IRAT Configuration, antenna tilting)
    - Check your scheduling algorithm
    - propose upgrade BW

    The only solution for high PRB is to add neighbor sites to balance load.

    dear
    if you want to balance traffic you can use MLB Feature,
    if the PRB Usage is very high you can close PreAllocation para,the PRB Usage will decrease but may can affect the UL Throughput
    open also DRX Feature will help you to decrease PRB usage

    thanks

    MLB feature requires a license. use the following commands if you want to setup Inter-freq MLB on the same site (dual carrier RF). Intra-Freq MLB can also be used depending on situation. the one below is just one example.ADD EUTRANINTERNFREQADD EUTRANINTERFREQNCELLMOD ENODEBALGOSWITCHMOD CELLMLBMOD CELLALGOSWITCHI've also attached Huawei's MLB poster and basic document. For detailed configurations, see the relevant hedex or feature description doc.
