Abstract
This application provides methods and apparatuses for uplink timing synchronization. The method includes: determining, based on beam information of a first beam and ephemeris information of the satellite base station, an uplink timing frame number of a first cell corresponding to the first beam; determining timing information of a first terminal device in the first cell based on the uplink timing frame number of the first cell, where the timing information is used to indicate a timing advance or a timing lag; and outputting the timing information.
