Abstract
Disclosed are a method and device for transmitting and receiving available channel information based on directivity in a wireless communication system. A method for enabling a station (STA) to receive available channel information in a whitespace band according to one embodiment of the present invention comprises the steps of: determining a current position of the STA and a position at which the direction is changed on a moving path of the STA; determining K (K≧1) operating ranges based on the current position of the STA and the position at which the direction is changed; transmitting a channel availability query (CAQ) request frame for the K operating ranges to a database; and receiving available channel information on the K operating ranges through a CAQ response frame from the database.
