ABSTRACT:
A first base station is adjacent to one or more second base stations, and the second base stations are adjacent to one or more third base stations. One or more frequency channels or subframes used by the third base stations are identified by the second base stations, which notify the first base station of the frequency channels or subframes used by the third base stations. The second base stations also notify the first base station of the frequency channels or subframes used by the second base stations. The first base station selects a working frequency channel or subframe based on this information. For example, the first base station may ignore any frequency channels or subframes used by the adjacent second base stations. The first base station may also give priority to the frequency channels or subframes used by the non-adjacent third base stations.
