The embodiment of the invention discloses a method and a device for distributing edge band resources and a base station, belonging to the field of mobile communication. The method comprises the following steps of: acquiring the using information of edge band resource blocks in adjacent modes through information interaction; determining usable edge band resource blocks in the adjacent modes during a next regulation period according to the using information of the edge band resource blocks in the adjacent modes and characteristic resource blocks; and distributing the determined usable edge band resource blocks in the adjacent modes for small areas which correspond to the adjacent modes during the next regulation period. The device comprises a using information acquisition module, a mode coordination module and a resource distribution module. The embodiment of the invention effectively prevents the potential interference on other small areas when two small areas or several small areas coordinate alone by adopting a scheme coordinating interference between the modes and achieves very good interference coordination effect, thereby reasonably distributing edge resources of the small areas and effectively increasing the integral throughput of a system and the throughput of edge users of the small areas.
