Abstract: This application provides example positioning methods and example apparatuses. One example method includes sending, by a positioning management network element, a positioning measurement request to a positioning measurement network element. The positioning measurement request is used to request the positioning measurement network element to feed back channel state information of a terminal device. Then, the positioning management network element receives a positioning measurement response from the positioning measurement network element. The positioning measurement response includes the channel state information of the terminal device. Then, the positioning management network element determines a location of the terminal device based on the channel state information of the terminal device.
