Abstract: Embodiments of this application disclose an indoor positioning method, a communication system, and a related device. The method in embodiments of this application includes an indoor terminal device receives first location information of a network device and second location information of a reconfigurable intelligent surface, to obtain a first reference signal, where the first reference signal is obtained by the reconfigurable intelligent surface by reflecting a location reference signal from the network device. The indoor terminal device determines a target location of the terminal device based on the first reference signal, the first location information, and the second location information.
