The invention provides a method and device for allocating cooperation resources of an orthogonal frequency division network. The method comprises the step of setting carrier power of center user equipment and carrier power of edge user equipment based on a disability factor of each cell base station within the limit of the total data transmission throughput of all base stations in an orthogonal frequency division network cooperation cell cluster under the condition that the total data transmission rate of the center user equipment of each orthogonal frequency division network cooperation cell cluster is set to be greater than a data transmission rate threshold of the center user equipment. The method aims at maximizing the system throughput and improves the system performance of the cell edge user equipment under the condition of ensuring the total data rate of the cell center user equipment to meet certain constraint conditions.
