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.

Claims20

Dependent claims

A terminal synchronization method implemented by a terminal, comprising:

obtaining a transmission interval for transmitting a set of synchronization signals within a time duration, wherein the transmission interval indicates a time interval between two adjacent synchronization signals of one set of synchronization signals from the terminal, and wherein the transmission interval is a configurable interval;
obtaining a starting offset for transmitting the set of synchronization signals, wherein the starting offset indicates an offset time from a starting time point of the time duration to a time point at which the terminal transmits a first synchronization signal of the one set of synchronization signals, and wherein the terminal obtains the starting offset based on a type of a synchronization reference with which the set of synchronization signals are synchronized;
and
transmitting the set of synchronization signals based on the transmission interval and the starting offset.
