Apparatus and method for transmitting coexistence beacon protocol packet in cognitive radio-based wireless communication system

The invention cognitive radio (CR: Cognitive Radio) based wireless communication system coexistence beacon protocol for communication between a base station in the shared information (Coexistence Beacon Protocol: CBP) relates to a packet transmission apparatus and method. CBP packet transmission method of a base station in a cognitive radio based systems, in accordance with the present invention, a self-coexistence windows: a through (Self-Coexistence Window SCW) slot, transmitting a CBP packet including the CBP identifier of the neighboring cell base station process, and in that it comprises the step of occupying a city, the SCW slot, the process of from the base station of the adjacent cell receives the CBP identifier list for the received successful CBP packet, the CBP identifier list may contain the CBP identifier It characterized. An orthogonal frequency division multiple access (OFDMA), cognitive radio (CR), self-coexistence windows (SCW), the coexistence beacon protocol (CBP)
