METHOD AND APPARATUS FOR DETERMINING TA FOR TERMINAL DEVICE Russian patent published in 2023 - IPC H04W56/00 

FIELD: communications.

SUBSTANCE: technical result consists in providing the ability to adjust the timing advance (TA) by the terminal device when the movement of the device is caused by both the terminal device and the satellite base station. After receiving the TA adjustment parameter sent by the access network device and determining that the TA of the terminal device needs to be adjusted, the terminal device determines the TA scaling factor, the subcarrier spacing parameter, and the first TA to jointly adjust the first TA to obtain the second TA. The TA adjustment parameter k is added when the terminal determines the second TA so that the TA adjustment range is larger. The TA may be used to determine the TA of a terminal when the terminal communicates with a satellite base station.

EFFECT: ability to adjust the timing advance (TA) by the terminal device when the movement of the device is caused by both the terminal device and the satellite base station.
