Abstract
The present document related to a method and apparatus for transceiving a signal capable of verifying the validity of an available channel in a wireless communication system. According to the present invention, a scheme for transceiving available channel information, a scheme for requesting/responding to a channel validity inquiry, and a scheme for transceiving a contact verification signal are provided, and accordingly, a scheme for supporting the accurate and efficient operation of an unlicensed device while protecting a licensed device in a whitespace band is provided.

16. A method of receiving a verification signal, which is received by a first mode station (STA) from a second mode STA in a wireless communication system, the method comprising:
-
receiving information on a white space map (WSM) from the second mode STA before operating in a white space band; receiving a contact verification signal (CVS) frame containing a map identifier (Map ID) of a currently valid WSM from the second mode STA; and comparing a value of the Map ID field contained in the CVS frame with a Map ID possessed by the first mode STA, wherein a time interval of the valid WSM is reinitialized based on the CVS frame when the value of the Map ID field contained in the CVS frame is identical to the Map ID possessed by the first mode STA. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27)

28. A method of transmitting a verification signal, which is transmitted by a second mode station (STA) to a first mode STA in a wireless communication system, the method comprising:
-
transmitting information on a white space map (WSM) to the first mode STA before the first mode STA operates in a white space band; and transmitting a contact verification signal (CVS) containing a map identifier (Map ID) of a currently valid WSM to the first mode STA, wherein a value of the Map ID field contained in the CVS frame and a Map ID possessed by the first mode STA are compared with each other in the first mode STA, and wherein a time interval of the valid WSM is reinitialized based on the CVS frame when the value of the Map ID field contained in the CVS frame is identical to the Map ID possessed by the first mode STA.

29. A first mode station (STA) device configured to receive a verification signal from a second mode station (STA) in a wireless communication system, the first mode station device comprising:
-
a transceiver configured to; receive information on a white space map (WSM) from the second mode STA before operating in a white space band; and receive a contact verification signal (CVS) frame containing a map identifier (Map ID) of a currently valid WSM from the second mode STA; and a processor configured to compare a value of the Map ID field contained in the CVS frame with a Map ID possessed by the first mode STA, wherein a time interval of the valid WSM is reinitialized based on the CVS frame when the value of the Map ID field contained in the CVS frame is identical to the Map ID possessed by the first mode STA.

30. A second mode station (STA) device configured to transmit a verification signal to a first mode station (STA) in a wireless communication system, the second mode station device comprising:
-
a processor configured to determine a white space map (WSM) for the first mode STA; and a transceiver configured to; transmit information on the white space map (WSM) to the first mode STA before the first mode STA operates in a white space band; and transmit a contact verification signal (CVS) containing a map identifier (Map ID) of a currently valid WSM to the first mode STA, wherein a value of the Map ID field contained in the CVS frame and a Map ID possessed by the first mode STA are compared with each other in the first mode STA, and wherein a time interval of the valid WSM is reinitialized based on the CVS frame when the value of the Map ID field contained in the CVS frame is identical to the Map ID possessed by the first mode STA.
