Abstract: Embodiments of this application disclose a resource scheduling method and a related device, to configure a scheduled resource for a terminal device based on a dynamic analog beam determined by a network device, thereby increasing a throughput of the terminal device. The method in embodiments of this application includes: The network device determines, based on information about an SRS of each first terminal device, a set of second terminal devices from a set of first terminal devices and static analog beam information of each second terminal device in the set of second terminal devices. Then, the network device determines beam domain channel information based on the static analog beam information. Therefore, the network device determines dynamic analog beam information of each second terminal device based on the static analog beam information and the beam domain channel information.
