Synchronization method and device

A synchronization method and apparatus are applied to a receiving node. The method comprises: acquiring wireless frame data from a sending node, the wireless frame data being carried on a wireless frame, the wireless frame data comprising a synchronization signal; and searching the synchronization signal in the wireless frame data on the wireless frame, and determining the position information of the synchronization signal in the wireless frame data. The position information is used for indicating the time-frequency position of the synchronization signal on the wireless frame. And determining a time calibration parameter of the receiving node according to the position information of the synchronization signal and the frame structure of the wireless frame, and calibrating a local clock of the receiving node according to the time calibration parameter and the local clock of the receiving node, so that the receiving node and the sending node are synchronized.
