Data transmission method, related device, and system

Abstract

This application provides an example data transmission method, a related example device, and an example system. One example method may include receiving, by a terminal device, indication information sent by a network-side device, where the indication information is used to indicate a receiving time period, and the receiving time period is after a power saving mode (PSM) period. The method also includes obtaining, by the terminal device, a timing advance (TA) value in the receiving time period. The method also includes sending, by the terminal device, data to the network-side device based on the TA value.
