1. method that is used for setting the transmitting gain of the one or more antennas of aerial array, described aerial array comprises a plurality of antennas, described method comprises:

  • Determine whether the transmission to subscriber equipment will be multiple-input and multiple-output MIMO transmission;

    If the described transmission to described subscriber equipment will not be the MIMO transmission;

    Determine one or more in path gain, signal attenuation or the path loss related with each antenna in the described aerial array;

    The power gain that will have the one or more antenna in maximum path gain, minimum signal attenuation and the minimal path loss is set at nonzero value;

    AndThe power gain of other antennas in the described aerial array is set at zero;

    If the described transmission to described subscriber equipment will be the MIMO transmission;

    Determine that described transmission will be " grade=1 " transmission or " grade=2 " transmission;

    AndBeing set at the power gain of each antenna in the described a plurality of antennas of described aerial array based on described transmission will be still " grade=2 " value of transmitting of " grade=1 " transmission.
