    Re: LOW HSDPA Throughput_Huawei NodeB

    Dear Miles,
    I think the first thing is to change your mindset about trouble shooting....just sending a graph will not give enough information to help you out..
    To trouble shoot :
    1) understand the...
  3. Re: Very Low HSUPA throughput in entire HUAWEI network

    Hello,
    low number of ERGCH will not cause you low HSUPA throughput but it might impact the soft handover for HSUPA ( it is used for HSUPA user in the soft handover region) if you have too many...

    Sorry mate .. no idea about Huawei Have you had checked the document ? I know it is nodeB parameters maybe you are checking the RNC parameter

    Cheers
  5. Re: Very Low HSUPA throughput in entire HUAWEI network

    hello
    sure there is when the RTWP is higher then use of the higher SF in UL can't maintain the quality (for example SF4 compared with the SF32)
    normally (in E*******) there is ROT (rise over...
  6. Re: Very Low HSUPA throughput in entire HUAWEI network

    Hello,
    something else can limit the HSUPA throughput is the RTWP... if you have high RTWP then the HSUPA throughput might decrease. There might be thresholds which might limit the allowed RTWP in...
  7. Re: Very Low HSUPA throughput in entire HUAWEI network

    sorry mate I am not familiar with Huawei
    in The RAB Assignment message you can see what is DL/UL limit which is a part of QOS implementation (even though you don't know about user profile in HLR)...

    hello
    when you are uploading a file, you need to look at the throughput .... if you are on HSDPA/HSUPA and downloading a file then your hsupa throughput will be low do you have this problem every...
  9. Re: Very Low HSUPA throughput in entire HUAWEI network

    Hello,
    if the UEs are capable of HSUPA , it first allocates HSDPA/HSUPA, normally users are downloading and UE sends small amount of data on HSUPA while it has HSUPA service (HSUPA always is with...
  10. Question Re: High UL CE Rejection with Low UL CE Utilization

    hello
    it could be due to different reasons:
    1) what is license limits ? maybe license is expired?
    2) CE admission threshold might be changed ?
    3) maybe ADCH reserved resources is high or reserved...

    Re: Decrease RRC NoReply Failure in LTE

    hi
    you should increase it from -115 to for example -105 dBm.. it is the target of receiving signal level in enodeB and also increase Pzeronominal for PUSCH
    just be careful too much increase of...

    Re: Decrease RRC NoReply Failure in LTE

    Hello,
    I think the equal (almost) parameter in LTE is preambleInitialReceivedTargetPower
    Besides you can think of slightly increasing PZeronominal power as well

    I had same issue in 3G but what I...

    Re: LTE RS power boost

    Hello,
    the idea of LTE is to have same power for each RE So the RE power is 80 watts/(Number of RB *12) which in you case will be 21.25 dBm
    pa is the power addition and reduction on CRS so you will...

    Re: Decrease CSFB Delay

    another point.. if your using IP RAN you may consider implementation of QOS in order to give higher priority on signaling on TN but it may help in congested TN or with high load
