The present invention discloses a method and an apparatus for determining a power offset parameter. The method for determining the power offset parameter provided in the present invention comprises: obtaining data throughput rate and/or cell resource usage state of a terminal; determining a resource state of the terminal according to the data throughput rate and/or the cell resource usage state and a corresponding threshold; determining power offset parameter configuration corresponding to the resource state according to the determined resource state; and sending the power offset parameter configuration to the terminal, so that the terminal determines the power offset parameter according to the power offset parameter configuration.
