    Default CAPACITY DIMENSIONING

    Hello experts, I have question about E******* 3G dimensioning, maybe you can help, can you tell me if this is correct?

    1. CE (Channel Elements) are dimensioned and pooled at NodeB level (if no BB) or at BaseBand (BB) levels
    2. Power is dimensioned (and pooled) at cell level, one PA per cell
    3. Codes are dimensioned (and pooled) at carrier level (one UARFCN =1 code tree = 15 HS codes+ 1 sig)
    4. Users’ licenses (HSD + EUL) are dimensioned (and pooled) at NodeB level (64 HSD users and 64 EUL users per NodeB, shared between the cells)


    Thanks !!

    Hello! find below my comments


    1. CE (Channel Elements) are dimensioned and pooled at NodeB level (if no BB) or at BaseBand (BB) levels - Correct
    2. Power is dimensioned (and pooled) at cell level, one PA per cell - You may have more than one cell per PA (for example, 2nd carrier)
    3. Codes are dimensioned (and pooled) at carrier level (one UARFCN =1 code tree = 15 HS codes+ 1 sig) - Correct, however remember that codes can be dinamically allocated for HSDPA and R99. The maximum code capacity for HSDPA is 15 SF16 codes, however normally up to 14 are actually used (if EUL is configured).
    4. Users’ licenses (HSD + EUL) are dimensioned (and pooled) at NodeB level (64 HSD users and 64 EUL users per NodeB, shared between the cells) - The number of users are licensed per cell (not per eNodeB).


    Regards,

    1. thanks for your support !! One thing I can also add that I just found, for point 2.
    2. Power is dimensioned (and pooled) at cell level, one PA per cell - You may have more than one cell per PA (for example, 2nd carrier) + you may also have several PA per cell(s) in case more power is needed, going from 20W to 40W ...
