SYNCHRONIZATION METHOD AND DEVICE, NETWORK ELEMENT, AND COMPUTER STORAGE MEDIUM

Disclosed is a synchronization method, comprising: sending first synchronization information carrying a synchronization signal and state information; after a first terminal receives synchronization information sent by a second terminal, receiving second synchronization information sent by a third terminal on the basis of the first synchronization information; if 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 transmitting the first synchronization information and receiving time information of the second terminal; sending third synchronization information, the third synchronization information being used for triggering synchronization of the third terminal and the first terminal; and synchronizing the first terminal and the third terminal according to the receiving time information of the third terminal. The present disclosure also provi
