Inter-cell interference coordination method and device

The invention relates to the technical field of communication, in particular to an inter-cell interference coordination method and device. The method is applied to a macro station, and comprises the following steps: when at least one micro station is included in a macro station cell range, dividing the macro station cell into a plurality of sub-regions; bandwidth resources are divided into a plurality of sub-frequency band resources, the sub-frequency band resources are distributed to the sub-areas, and the frequency bands of the sub-frequency band resources distributed to the sub-areas are different; determining a first area comprising a macro station cell, and clustering each micro station in the first area to obtain at least one micro station cluster; determining a target micro-station cluster of which the cluster center position is located in the macro-station cell from the at least one micro-station cluster; and allocating sub-band resources to the target micro-station cluster according to the position o
