    Default How To Solved Low UL THP in LTE [Huawei 10 MHZ]

    Dear Expert,

    pls help me,how to increase UL THP in LTE Huawei 10MHZ:
    We have done this step but still not improved:
    1.Downtilt
    2.SINR and RSRP good situation
    3.SmartPreAllocationSwitch actived

    pls help me master....

    Hi,

    Some suggestions:

    1) Check that the transmission capacity is well dimensioned.
    2) Test the transmission for packet loss: Run a ping test from eNodeB to MME with different packet sizes (up to 1500 bytes at least), if you get packet loss then definitely there is a Tx problem
    3) Review if the number of users is high, this will have impact on throughput.
    4) Review the uplink interference stats, to see if the uplink is becoming a bottleneck.
    5) There are a couple of features that can help you for cell edge users: Interference Rejection Combining (IRC), Intra-eNodeB UL CoMP. Check if they are available.
    6) Use a tool like FMA (you can find it in the forum) to compare the configuration from your problem eNodeB with another one performing correctly.

    Hope this helps

    Hi,
    i just do this step:
    the same step what you give,but slightly not improved:
    Test 1 done
    Test 2 done
    Test 3 RB, dn RRC user
    Test 4 done, ul inteference turun by attenuation dn deaActive neighbor Cell
    Test 5, ICIC feature done , ul comp a3 decreased inteference neighbor


    what should i have done again,
    I have try,but no improved.

    pls exepert give me some cheat.

    Hi coach

    How can we check the transmission for packet loss?

    you said that "Run a ping test from eNodeB to MME with different packet sizes (up to 1500 bytes at least), if you get packet loss then definitely there is a Tx problem"

    is there any command for ping?

    Hi,

    yes, there is a command for HW, you just write "PING"

    Hi Mates,
    If you re re-driving this area, getting still low throughput. You can add this to below checks

    1-Time of drive check (not busy hour) as you checked users (hourly)
    2-Check CQI and MCS
    3-This occuring in specific spots or in general.
    4- If in general you can try different type of Handset.

    Let us know if that helped.

    Hi

    Did you checked PRB Utilization on UL ? , if its high try to go for reducing coverage or adding layer.
    which layer are you having issue on ? L18 , L26 , L9 ?
    What is the Actual RSRP at the location , can you check from NASTAR the live RSRP and ECNO. ?
    Do check the Packet Loss Rate for the site and TCP Delay for the user is it higher than 10,000 ?
