1. Method for controlling the interference level generated by a mobile station communicating with a current base station on at least a neighbor base station in a wireless communication system, comprising at least steps:

  • A;

    selecting at least one neighbor base station;

    B;

    estimating a first attenuation value representative of signal attenuation level between the mobile station and the current base station, and at least a second attenuation value correlated to one neighbor base station selected in step A and representative of signal attenuation level between the mobile station and the correlated neighbor base station;

    C′

    ;

    estimating a first received signal strength by measuring power level of signal received by the current base station from the mobile station;

    C″

    ;

    estimating an interference level from the relation;


    I_level=BS0

    RSS+L0

    L,
    in whichI_level is the interference level,BS0_RSS is the first received signal strength,L0 is the first attenuation value, andL is one second attenuation value estimated in step B,D;

    comparing the interference level to a reference interference level, and according to the result of the comparison, sending to the mobile station at least information relative to a maximum transmitted signal strength for the mobile station.
