    Abstract: Disclosed are a method and an apparatus for transmitting a channel switching information. A method for transmitting switching information of an operating channel may comprises the step of: receiving a candidate channel frame including channel switch candidate information through the operating channel, and preferentially scanning a candidate operation channel induced based on the channel switch candidate information if the operating channel is changed, wherein the candidate operation channel may be a channel having a possibility of being preferentially selected when the operating channel is changed to another channel. As a result, when an access point (AP) shifts the operating channel, the shifted channel can be quickly scanned and associated with AP.
