Apparatus and method for transmitting coexistence beacon protocol in a cognitive radio system

A method for transmitting Coexistence Beacon Protocol (CBP) in a cognitive radio system, the method comprising:

• scanning channels on which a plurality of neighboring Base Stations (BSs) operate, using a plurality of directional antennas;
• linking the plurality of directional antennas with the plurality of neighboring BSs, respectively;
• and
• receiving at least one CBP packet through one of the plurality of directional antennas respectively linked with the plurality of neighboring BSs, and transmitting the received at least one CBP packet to at least one or more other BSs linked with at least one or more other directional antennas.

An operation method of a Base Station (BS) for transmitting Coexistence Beacon Protocol (CBP) in a cognitive radio system, the method comprising:

• permitting access of a Mobile Station (MS) according to a preset process;
• identifying if the MS includes a dedicated equipment transmitting a CBP packet;
• if the MS is identified as the dedicated equipment, gathering corresponding information from the dedicated equipment transmitting the CBP packet;
• and
• scheduling CBP packet transmission according to the corresponding information.
