A method and device for quiet period synchronization are provided in the present embodiments. The method includes: a quiet period configuration of a common control channel coverage area is acquired; the same cognitive frequency point in the quiet period configuration is provide with the same quiet period configuration; a quiet period configuration information is broadcasted to the common control channel coverage area according to the quiet period configuration; the quiet period configuration information is used for configuring the same quiet period configuration to devices provided with the same cognitive frequency point in the common control channel coverage area; and the quiet period configuration information comprises a cognitive frequency point, a quiet period cycle of the cognitive frequency point, a quiet period offset and quiet period duration. The present embodiments solves the problem of quiet period asynchronization between cognitive cells in prior art, and improves the spectrum efficiency.
