Abstract
Provided is a method for sensing a channel of a whitespace band in a wireless LAN system. A method for sensing and reporting a channel of a whitespace band in a wireless LAN system according to one embodiment of the present invention comprises the steps of: receiving a sensing request including a candidate report channel and a target channel of a whitespace band to be sensed; sensing the target channel; and determining a channel for transmitting sensed results in accordance with whether a licensed user is detected on the target channel, and transmitting the sensed results.
