Abstract
A spectrum detection method, system and base station are provided, which relate to the field of communications technology, and improve the spectrum utilization in a cellular multi-hop network. The spectrum detection method includes: receiving an intermediate spectrum detection result sent by each node; and integrating the intermediate spectrum detection results to obtain a final spectrum detection result. The spectrum detection method, system, and base station are mainly applied to cellular multi-hop networks.
