1. A data transmission method, comprising:
receiving, by a terminal device, indication information sent by a network-side device before a power saving mode (PSM) period, wherein the indication information is used to indicate a receiving time period for the terminal device to obtain a current timing advance (TA) value, the receiving time period is after the PSM period, and the network-side device includes a satellite base station;
obtaining, by the terminal device, a TA value in the receiving time period indicated by the received indication information; and
sending, by the terminal device, data to the network-side device based on the TA value.
