Abstract: This application discloses a quasi co-located relationship management method and apparatus. In this application, a terminal side device and a network side device determine one or a plurality of measurement quantities for managing a quasi co-located relationship, and manage or use the quasi co-located relationship based on the determined one or plurality of measurement quantities. According to the solutions of this application, when there are the plurality of measurement quantities, both the terminal side device and the network side device manage or use the quasi co-located relationship based on the determined one or plurality of measurement quantities, so that behavior of the terminal side device and behavior of the network side device can be aligned. This improves communication reliability.
