METHOD AND APPARATUS FOR TRANSMITTING CHANNEL INFORMATION IN COGNITIVE RADIO NETWORK AND METHOD AND APPARATUS FOR PERFORMING CHANNEL SWITCHING

WIPO Patent Application WO/2012/081921

A3

A method and apparatus for transmitting channel information used by a station form among TV white space channels, and a method and apparatus for performing channel switching are disclosed. A method for transmitting information of a channel used by a station from among TV white space channels includes determining one or more channels used by the station from among channels contained in a plurality of OFDM blocks, wherein each OFDM block includes one or more contiguous channels from among the TV white space channels, generating a message including first information indicating the lowest channel number from among channels contained in a first OFDM block from among the plurality of OFDM blocks, second information indicating the lowest channel number from among channels contained in a second OFDM block, third information indicating the one or more channels used by the station as bitmap information, and fourth information indicating a total amount of bandwidth used by the station, and transmitting the generated message.
