1. A synchronization method, applied to a first terminal, the method comprising:
sending first synchronization information carrying a Synchronization Signal (SS) and state information to a third terminal, the state information being used to indicate a current state of the first terminal;
receiving second synchronization information sent by the third terminal based on the first synchronization information after the first terminal has received synchronization information sent by a second terminal, the second synchronization information comprising: a SS and state information of the third terminal, and the state information of the third terminal being determined according to the state information of the first terminal;
under a condition that the state information sent by the third terminal indicates that the third terminal enters a pre-synchronization state, determining receiving time information of the third terminal according to time domain resources used for transmission of the first synchronization information and receiving time information of the second terminal;
sending third synchronization information, the third synchronization information being used to trigger the third terminal to be synchronized with the first terminal; and
synchronizing the first terminal with the third terminal according to the receiving time information of the third terminal.
