    I hope this time it works.

    What is the criteria and data used when determining power control parameters? I know eight of them (Please feel free to add if I have missed any)

    1. The minimum quality level threshold which power control algorithm is triggered to increase the power when rxQuality becomes higher than some value (e.g. rxQual=>5).

    2. The maximum quality level threshold which power control algorithm is triggered to decrease the power when rxQuality becomes lower than some value (e.g. rxQual

    One more time.

    Okay, I give up. No more power control parameters.
    Sorry for these nonsensical messages.

    try not to use arithmetical symbol, but “greater than” or “lower than” ? Maybe the symbols are misunterpreted by the server.

    power control is based solely on RxLev and RxQual.
    1- If too low RxLev AND RxQual within acceptable range
    then increase Tx Level
    2- If too high RxLev AND too good RxQual
    then reduce Tx Level
    3- If too poor RxQual AND (Rxlev within range or RxLev too high)
    then increase Tx Level
    4- If too poor RxQual AND too low RxLev
    then increase Tx Level

    It’s all very logical. RxQual has priority, so if RxQual is too poor, the Tx level will increase, even if the RxLev is too high already (that’s a typical interference case).

    Here are the main parameters:

    DL Upper RxLev Limit = -75dBm
    DL Lower RxLev Limit = -85dBm
    DL Upper RxQual Limit = 1
    DL Lower RxQual Limit = 4

    UL Upper RxLev Limit = -85dBm
    UL Lower RxLev Limit = -95dBm
    UL Upper RxQual Limit = 1
    UL Lower RxQual Limit = 4

    Check also the average window times (should be half the current emergency HO window size).
