Abstract: Related to the technical field of communication, validity period determinations are provided. For example, a terminal determines a validity period of ephemeris information, the validity period meeting a synchronization requirement of the terminal. By determining the validity period of the ephemeris information that meets the synchronization requirement, the terminal can ensure the real-time accuracy of the ephemeris information at the terminal, thereby ensuring that a time delay and a Doppler frequency shift calculated by the terminal based on the ephemeris information have only small errors. Since the errors do not exceed a range tolerated by the synchronization requirement, the synchronization performance of the terminal can be guaranteed.
