1. A method for time synchronization determination, comprising:
receiving, by a terminal device, a handover command from a first device, the first device being a device currently accessed by the terminal device, and the handover command indicating that the terminal device hands over from the first device to a second device;
obtaining and determining, by the terminal device, time synchronization information of the second device, wherein the time synchronization information comprises one or more of: an indication of whether the terminal device performs propagation delay compensation, and an indication of whether the second device has performed propagation delay compensation; and
determining, by the terminal device, whether to perform propagation delay compensation according to the indication of whether the terminal device performs propagation delay compensation, and/or
determining, by the terminal device, whether the second device has performed propagation delay compensation and/or whether the terminal device needs to perform propagation delay compensation according to the indication of whether the second device has performed propagation delay compensation.
