摘要： The present invention provides a method and a base station for spectrum sharing, including: determining a first frequency band, a second frequency band, and a third frequency band, where the first frequency band and the second frequency band are used for communication of a second network, a first network performs communication by using the second frequency band and the third frequency band, and the second frequency band and the third frequency band form a carrier of the first network. Because the first network and the second network share the second frequency band, frequency band utilization efficiency can be improved, and a spectrum waste can be reduced.

摘要： Embodiments of the present invention provide a method and a device for reducing intermodulation interference. The method includes: performing real-time estimation according to time domain information of M downlink transmit signals, to obtain a first intermodulation interference signal; and canceling, according to the first intermodulation interference signal, intermodulation interference generated by the M downlink transmit signals in an uplink receive signal, where M is an integer greater than or equal to 2, and the M downlink transmit signals are baseband signals that are transmitted on M carriers and that are not combined. Based on the foregoing solutions, first intermodulation interference obtained by performing real-time estimation on time domain information of M downlink transmit signals approximates intermodulation interference that is actually generated by the M downlink transmit signals in an uplink receive signal, so that the actually generated intermodulation interference can be effectively canceled, thereby reducing intermodulation interference and improving system performance.
