Abstract: This application provides a method for reducing interference between a radar and an uplink frequency band. A first network device obtains a characteristic of a radar signal on the uplink frequency band, and determines a corresponding protection measure based on the characteristic of the radar signal, to reduce interference between the radar signal and the uplink frequency band. In this way, when 5G communication collides with the radar in time domain and frequency domain of the uplink frequency band, the 5G communication and the radar can still coexist. This improves utilization of a wireless spectrum.

Abstract: This application discloses a method including: A network device receives first channel quality information corresponding to a first bandwidth and second channel quality information corresponding to an aggregated bandwidth from a terminal device; determines interference experienced by the terminal device when the terminal device accesses the aggregated bandwidth based on the first channel quality information and the second channel quality information; and sends bandwidth configuration information to the terminal device based on the interference. The first channel quality information is sent by the terminal device when the terminal device accesses the first bandwidth, and the second channel quality information is sent by the terminal device when the terminal device accesses the aggregated bandwidth. The aggregated bandwidth is obtained by aggregating at least the first bandwidth and a second bandwidth. A spectrum of a third bandwidth is spaced between a spectrum of the first bandwidth and the second bandwidth.
