Abstract: One embodiment of the invention describes a synchronization signal sending method applied to an unlicensed frequency band. To ensure transmission fairness, a network device performs listen before talk (LBT) before a start time for transmitting a synchronization signal, to determine whether a channel is busy or idle. When the channel is busy, the network device cannot transmit the synchronization signal at the expected start time for transmitting the synchronization signal. Therefore, the network device performs LBT again within a preset time length after the start time, and sends the synchronization signal when determining that the channel is idle by performing LBT again. When the channel is idle, the network device preempts a channel resource, and sends the synchronization signal the expected start time for transmitting the synchronization signal.
