Claim
1. A spectrum allocation method, comprising:
determining, by a first base station, according to first broadcast information sent by at least one second base station, usage of a preferred frequency band of the at least one second base station; and determining, by the first base station, according to the usage of the preferred frequency band of the at least one second base station, use of the preferred frequency band of the at least one second base station by the first base station.
2. The method according to claim 1, wherein determining, by the first base station, according to the usage of the preferred frequency band of the at least one second base station, use of the preferred frequency band of the at least one second base station by the first base station comprises:
if the first base station determines, according to the first broadcast information, that the second base station does not use or uses a part of the preferred frequency band of the second base station to transmit data, determining, by the first base station, to transmit data on all or a part of the preferred frequency band of the second base station; or if the first base station determines, according to the first broadcast information, that the second base station uses the preferred frequency band of the second base station to transmit data, determining, by the first base station, to exit from all or a part of the used preferred frequency band of the second base station.

exiting, by the first base station, from the all or the part of the used preferred frequency band of the second base station after first set time.
4. The method according to claim 1, further comprising:
transmitting, by the first base station, data on a preferred frequency band of the first base station.
