Abstract: Embodiments of this application relate to the communications field, and provide a terminal synchronization method and a terminal. A terminal sends synchronization signals in a distributed manner by controlling a sequence for sending the synchronization signals, so that terminals in a vehicle to vehicle communications system can have uniform timing. The method includes: obtaining, by a terminal, a configurable transmission period for sending a first synchronization signal; and sending, by the terminal, the first synchronization signal based on the configurable transmission period.
