Abstract: Embodiments of this application provide an antenna resource scheduling method and a device, and relate to the field of antenna technologies, to improve radiation efficiency of an antenna in a sideband area of an operating band band. A main solution is: obtaining, by the device, an operating frequency of an antenna, where the operating frequency is a frequency currently used by the device during communication; determining an operating band based on the operating frequency, where the operating band is a band to which the operating frequency belongs; determining a target impedance parameter based on the operating band and the operating frequency; and adjusting an impedance parameter of an impedance circuit to the target impedance parameter. The embodiments of this application are used for resource scheduling.
