Abstract: This application provides a TA determining method and apparatus for a terminal device. After receiving a TA adjustment parameter sent by an access network device and determining that a TA of the terminal device needs to be adjusted, the terminal device determines a TA scaling factor, a subcarrier spacing parameter, and a first TA, to jointly adjust the first TA to obtain a second TA. ATA adjustment parameter k is added when the terminal device determines the second TA, so that an adjustable range of the TA is larger. Therefore, the TA may be applied to determining the TA of the terminal device when the terminal device communicates with a satellite base station. In this way, the terminal device can adjust the TA when movement of a device is caused by both the terminal device and the satellite base station.
