    Default UL INTERFERENCE PRACH

    Hi friends,

    Can you help me to indentify which would be the problem caused by increased these counters [UL_INTERFERENCE_PRACH_INDEX0, 1, 2 & 3], is a urban site but this behavior was ocurred after parameter activation as follow:

    CELLDLSCHALGO,RBGALLOCSTRATEGY=ADAPTIVE;
    CELLDLPCPDSCH,CCUPA=PA_0,CEUPA=PA_0;
    CELLPDCCHALGO,PDCCHSYMNUMSWITCH=ECFIADAPTIONON;
    CELLALGOSWITCH,IRCSWITCH=PucchIrcSwitch-1,INTERFRANDSWITCH=ENB_BASED;
    CELLDLSCHALGO,ENBINTERFRANDMOD=MOD3;
    PUSCHPARAM,DeltaOffsetCqiIndex=15;
    CELLALGOSWITCH,CQIADJALGOSWITCH=DlVarIBLERtargetSwitch-1&AdaptiveStepVarySwitch-1;

    Can you help me to decrease these counters, also was a access degradation of 99.87 to 99.85, throughput increased 2Mbps.

    Thanks in advance.
