The present disclosure provides a paging synchronization method, applied to a base station, and including: when it is determined that transmission of a synchronous signal block (SSB) for synchronization of a terminal is disabled, configuring a reference signal for paging synchronization for a paging occasion (PO) to be transmitted to the terminal; and transmitting the reference signal to the terminal, to enable the terminal to perform paging synchronization based on the reference signal. Therefore, the present disclosure can ensure that the terminal has a higher paging reception performance, and improve the paging synchronization efficiency.
