    try to relief the traffic toward less loaded cell by changing reselection, handovers parameters or use load control algorithm....2nd carrier implemenatation is another option as well.

    in wcdma we have code tree per Scrambling code ..if one sector having code tree congestion and other sector is having low code utilization.. can we improve the code congestion through parameters(Huawei)..please comment.

    Power Blocking:- When an UE start call setup process it sends 4 succesive aceess preamble's(+-1 db) to Node B on the feedback of open loop power control which is basiclly used to overcome near-far effect. If after 4 successive access preambles Node B doesnt aknowlade to mobile than it comes under power blocking.

    Another power blocking is happen's due to Noise floor rise above the thresold value 6-7 db typically. The feedback system for this is closed loop power control.

    Channel Element Blocking:- It's direcetly related to the insufficient resources to mature a call. There is one channel card called CCU which contains 128 CE's for perticular carrier of the Node B.

    For more studies about blocking preffer page no 251 & 253 of attached documents.

    Re: what is power congestion and Code Congestion ?

    According to my opinion

    UL power congesstion can increased
    Verify to increase ENU& careful RTWP
    Verify to decrease HSUPA user no.
    Control coverage cariful SHO margin enough?
    DL power congesstion
    Increase Power Resource(refer power RRU careful power alarm mismatch)
    CPICH Power decreased 1db step
    Optimize Load reshuffle
    New coverage
    can infromation more
    Thank alot
