<p>Embodiments of the present invention provide a method, device, and data frame for spectrum sensing. The method for spectrum sensing includes: determining configuration information of a spectrum sensing guard interval in a guard period GP used to prevent interference, where the spectrum sensing guard interval is used to prevent interference caused by signal transmission to spectrum sensing, and the configuration information is used to indicate a position of the spectrum sensing guard interval in the guard period; setting a quiet period in the guard period according to the configuration information of the spectrum sensing guard interval; and performing the spectrum sensing in the quiet period. In the present invention, the guard period in a transmission frame is used again, and the quiet period is set in the guard period, thereby ensuring the compatibility with an existing protocol; and the spectrum sensing guard interval including a front guard interval and/or a back guard interval is set, thereby effectively avoiding the interference caused by the signal transmission to the spectrum sensing, and the spectrum sensing is performed in the condition that the signal transmission is not affected.</p> |
