    Is there any way to improve the performance of a cell with high Timing Advance users. (Tilting or increasing Rx_Lev_min is not an option)

    These are some actions you can carry out, if the cell is isolate:
    -disable Power Control
    -choose High Power TRX with good sensibility at reception
    -if the traffic is not to high downgrade the capacity to improve the coverage
    -deploy a repeater if necessary or just a LNA if the DL coverage is OK
    If users are far enough (TA>=63) you can change the cell into an extended cell with the outer zone reserve to these users

    Thanx Lemaure.

    Could you please tell me more about “Extended Cell”. I’m using Alcatel-Lucent soulutions. Where can I find good documents about these?

    You can as well limit the coverage by modifying parameter “Hand Over on Timing Advanced” (usually called distance handover” in your BSS)

    Tilting could be a good choice if you dont need the cell to cover a large area as the cell can create as well interferences.
