Method and apparatus for transceiving a contact verification signal in a wireless communication system

A method of transmitting a verification signal, which is transmitted by a second station (STA) to a first STA in a wireless communication system, comprising the steps of:

• transmitting information on a white space map (WSM) to the first STA before the first 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 STA,
• wherein a value of the Map ID field contained in the CVS frame and a Map ID possessed by the first STA are compared with each other in the first STA, wherein the CVS frame further comprises a field indicating a time interval of which the CVS frame is transmitted from the second STA, and wherein the CVS frame is received on the every time interval of a CVS transmission.

A first station (STA) device configured to receive a verification signal from a second station (STA) in a wireless communication system, comprising:

• a transceiver configured to receive information on a white space map (WSM) from the second STA before operating in a white space band and configured to receive a contact verification signal (CVS) frame containing a map identifier (Map ID) of a currently valid WSM from the second 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 STA,
• wherein the CVS frame further comprises a field indicating a time interval of which the CVS frame is transmitted from the second STA and wherein the CVS frame is received on the every time interval of a CVS transmission.

A second station (STA) device configured to transmit a verification signal to a first station (STA) in a wireless communication system, comprising:

• a processor configured to determine a white space map (WSM) for the first STA;
• and
• a transceiver configured to transmit information on the white space map (WSM) to the first STA before the first STA operates in a white space band and configured to transmit a contact verification signal (CVS) containing a map identifier (Map ID) of a currently valid WSM to the first STA,
• wherein a value of the Map ID field contained in the CVS frame and a Map ID possessed by the first STA are compared with each other in the first STA, wherein the CVS frame further comprises a field indicating a time interval of which the CVS frame is transmitted from the second STA, and wherein the CVS frame is received on the every time interval of a CVS transmission.
