A method for configuring frequency resources of a base station, the method comprising: dividing allowable operating bands satisfying allowable operating bandwidths, of a cell into a number of elementary frequency resources in elementary units of frequency resources according to a preset correspondence relationship between the allowable operating bandwidths and the elementary units of frequency resources of the cell; determining a frequency priority coefficient of each elementary frequency resource, wherein the frequency priority coefficient characterizes interference for the cell, from respective adjacent cells adjacent in position to the cell in the elementary frequency resource, and/or loads of the respective adjacent cells in the elementary frequency resource; the loads of the adjacent cells in the elementary frequency resource range from 0 to 1, wherein "0" indicates that the elementary frequency resource accessible to the adjacent cells is not used, and "1" indicates that the elementary frequency resource accessible to all of the adjacent cells is used; and allocating a frequency resource for the cell according to the frequency priority coefficients of the elementary frequency resources; if a value of the frequency priority coefficient of the elementary frequency resource is larger, a priority at which an elementary frequency resource is allocated is lower, the interference is larger, if a value of the frequency priority coefficient of the elementary frequency resource is 0, a priority at which an elementary frequency resource is allocated is highest, the interference is smallest; wherein the interference is ratios of interference measured values of the adjacent cells to the cell to the quantified largest interference value, wherein the interference measured values of the adjacent cells to the cell are measured strength values of Reference Signal Received Power, RSRP, or other reference signals of the adjacent cells measured in the cell. dividing allowable operating bands satisfying allowable operating bandwidths, of a cell into a number of elementary frequency resources in elementary units of frequency resources according to a preset correspondence relationship between the allowable operating bandwidths and the elementary units of frequency resources of the cell; determining a frequency priority coefficient of each elementary frequency resource, wherein the frequency priority coefficient characterizes interference for the cell, from respective adjacent cells adjacent in position to the cell in the elementary frequency resource, and/or loads of the respective adjacent cells in the elementary frequency resource; the loads of the adjacent cells in the elementary frequency resource range from 0 to 1, wherein "0" indicates that the elementary frequency resource accessible to the adjacent cells is not used, and "1" indicates that the elementary frequency resource accessible to all of the adjacent cells is used; and allocating a frequency resource for the cell according to the frequency priority coefficients of the elementary frequency resources; if a value of the frequency priority coefficient of the elementary frequency resource is larger, a priority at which an elementary frequency resource is allocated is lower, the interference is larger, if a value of the frequency priority coefficient of the elementary frequency resource is 0, a priority at which an elementary frequency resource is allocated is highest, the interference is smallest; wherein the interference is ratios of interference measured values of the adjacent cells to the cell to the quantified largest interference value, wherein the interference measured values of the adjacent cells to the cell are measured strength values of Reference Signal Received Power, RSRP, or other reference signals of the adjacent cells measured in the cell.
