Disclosed is a base station frequency resource allocation method, for achieving proper allocation of base station frequency resources to avoid or reduce inter-cell interference. The method comprises: determining each basic frequency resource in each allowed operating band conforming to selectable operating bandwidth of a cell; determining a frequency priority coefficient of each basic frequency resource, the frequency priority coefficient representing interference from each neighboring cell that is adjacent to the cell in location with the cell in the basic frequency resource, and/or load of each neighboring cell in the basic frequency resource; and allocating frequency resources to the cell according to the frequency priority coefficients of the basic frequency resources. Also disclosed is a network device.
