1. A timing advance (TA) determining method for implemented in a terminal device, the method comprising:
obtaining a TA adjustment parameter from an access network device, wherein the TA adjustment parameter is used to indicate a TA adjustment of the terminal device;
determining a TA scaling factor of the terminal device, a subcarrier spacing parameter of the terminal device, and a first TA used when the terminal device communicates with the access network device before receiving the TA adjustment parameter, wherein the TA scaling factor is used to perform scaling processing on the TA adjustment of the terminal device; and
determining a second TA based on the TA adjustment parameter, the TA scaling factor, the subcarrier spacing parameter, and the first TA.
