Updating information for uplink synchronization

Abstract

Example embodiments of the present disclosure relate to a terminal device, a network device, methods, apparatuses and a computer readable storage medium for updating information for uplink synchronization. The terminal device determines a first threshold duration for first information for uplink synchronization and a second threshold duration for second information for the uplink synchronization; and performs a first procedure for updating the first information and a second procedure for updating the second information based on: determining that a validity duration of one piece of information expires and a remaining validity duration of the other piece of information is shorter than corresponding threshold duration. As such, the two procedures updating the first information and the second information may be aligned with each other, thus the complexity can be reduced, the power consumption can be reduced, and the communication efficiency may be improved.
