    Abstract: Embodiments of the present invention provide a spectrum detection method and apparatus, and a base station. According to the method, in the embodiments, a first base station sends spectrum detection information to an auxiliary device, where the spectrum detection information is used to instruct the auxiliary device to detect whether a first spectrum is occupied; then, the first base station receives first spectrum status information sent by the auxiliary device, so that the first base station determines whether the first spectrum in an area in which the auxiliary device is located is occupied. Therefore, it is implemented that the first base station may determine whether user equipment is interfered by another communications system device in a process in which the user equipment uses the first spectrum, so as to implement sharing of a spectrum by the user equipment with the another communications system device.
