Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1. 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…
