The invention discloses a power control method. The method includes the following steps that: when judging that the intensity of the interference of a local cell on a neighboring cell is greater than a predetermined value, a base station determines that power control needs to be performed on user equipment (UE) in the local cell; the base station judges the interference sources of the local cell, when the base station judges that the interference sources of the local cell are only high-power users, the power control parameters k1 and b1 of the high-power user equipment are decreased according to a formula described in the descriptions of the invention, a reduced high-power user equipment target signal to interference plus noise power ratio SINRpusch-target can be obtained; and the base station decreases the uplink transmitting power of the high-power user equipment according to the reduced high-power user equipment target signal to interference plus noise power ratio and informs the high-power user equipment. With the power control method of the present invention adopted, power control can be performed on a high-power terminal when interference is severe.
