    Dear Huawei Experts

    There is one parameter in Huawei inner PCU (Maximum Ratio Threshold of PDCHs in a cell)

    Its value is in percent (default=30 %)

    What does this parameter mean? Is it for static or dynamic data TSs?
    Please your advices
    …

    Thanks in advance

    Hi HW_Junior,

    This parameter is used to restrict the percentage of TSs that can be used as PDCHs (both static and dynamic).

    Consider a typical 4TRX cell with 1BCCH and 2 SDCCHs. Then:
    Total number of TSs that can be used for traffic(voice or data)=4*8 – 3 = 29.

    Now, if ur ‘maximum ratio threshold of PDCHs in cell’ is 30 for this cell, then:
    Maximum no. of PDCHs = 0.3*29 = 8.7. This means that a maximum of 9 TSs in this cell can be used as PDCHs.

    This also means that if you have eg 2 static PDCHs, then you can have a maximum of 7 dynamic PDCHs.

    Regards,
    SHELDON

    Hi Sheldon

    Thanks for information.
    As I know for static TS I should add PDTCH to Channel Type. If I don’t have any PDTCH TS in a cell and Maximum Ratio Threshold of PDCHs is 30 %.
    What does it mean in this case?
    Is there any static TS in 30% if I have not added PDTCH to TRX.

    Thanks in advance

    Hi HW_Junior,

    This threshold applies to the sum of all PDCHs, whether static or dynamic.

    If you don’t have any static PDCHs (PDTCH TSs) in a cell, then this threshold will only apply to the dynamic PDCHs. That is, a maximum of 30% of TCHs in that cell can be used as dynamic PDCHs.

    Hello Mr HW_Junior.

    In Huawei Maximum Ratio Threshold of PDTCH in a cells we go for only 30%. And we can use this because user can use multi-slot channel when they use the data.

    If we go for 30 then it comes around 1.8 that is equal to 1, so if you want to use multi-slot then go for more than 30%. And for maximum conversion we are using different parameter in Huawei.

    Sheldon is right. You can change the threshold if you want more .
