Claim 11:
12. The method according to claim 11, further comprising:
obtaining, by the terminal, a transmission delay difference value, wherein the transmission delay difference value is a transmission delay difference value between a current serving cell and a neighbor cell received by the terminal, or a transmission delay difference value between a current serving cell and a target cell after cell switching, or a transmission delay difference value obtained by deducing after performing subtraction operation when the terminal obtains TAs or transmission delays of a plurality of cells; and
obtaining, by the terminal, a new time point by increasing the transmission delay difference value by taking a time of a current serving cell as a datum, measuring a synchronization signal and PBCH block (SSB) of a neighbor cell or a target cell at the new time point, and establishing downlink synchronization with a network or obtaining broadcast information at the neighbor cell or the target cell.
