Embodiments of this application disclose a cross-standard scheduling method and a base station, used for unified scheduling of UEs in different standards by using a unified scheduler, to achieve space division multiplexing of a spectrum resource, where different standards may share the spectrum resource. A unified scheduler is disposed in the base station in the embodiments of this application. The method and the base station may obtain downlink channel information of UEs operating using different standards and in overlapping coverage range. The method and the base station may determine a scheduling result using the unified scheduler based on the obtained downlink channel information of the UEs. The method and the base station may schedule the UEs based on the scheduling result.
