Abstract
An apparatus and method for transmitting Coexistence Beacon Protocol (CBP) in a cognitive radio system are provided. The apparatus includes a detector, a controller, and a transmitter. The detector scans channels on which neighboring Base Stations (BSs) operate through a plurality of directional antennas. The controller links the plurality of directional antennas with BSs, respectively. The transmitter receives a CBP packet through the directional antenna linked with the BS, and transmits the received CBP packet to at least one or more other BSs linked with at least one or more other directional antennas.
