Abstract: PURPOSE: A CBP packet transmitting apparatus and method in a wireless communications system based on CR(Cognitive Radio) are provided to select a proper competitive target through the analysis of surrounding WRANs and increase the SCW life cycle in a WRAN which is defeated in competition, thereby setting a high reliable SCW rule pattern while preventing collision between CBP packets. CONSTITUTION: If entering a channel, a pattern analyzer(1132) analyzes the SCW(Self Coexistence Window) rule patterns of surrounding WRANs(Wireless Regional Area Networks). In case an unoccupied SCW slot is not periodically generated, a competition selector(1134) selects a WRAN having the shortest SCW life cycle as a competitive target. A backoff timer(1136) creates a random backoff time for competition with the competitive target at a start point of time of an SCW slot in which the competitive target transmits a CBP(Coexistence Beacon Protocol) packet. If the random backoff time is expired before the reception of the CBP packet of the competitive target, a RF(Radio Frequency) transmitter(1128) transmits the CBP packet.

Based on the priority, the satisfactory state of a quality of service(QOS) with respect to a CBP packet is successively determined. A channel(201) with a first priority among channels satisfying the QOS is selected as a channel for the transmission of the CBP packet. The CPB packet is transmitted through the selected channel.

Abstract: PURPOSE: An apparatus and a method for transmitting a coexistence beacon protocol packet in a cognitive wireless communication system are provided to determine a WRAN(Wireless Regional Area Network) which will transmit a CBP packet through competition in a frequency shaft, thereby improving efficiency of CBP transmission without influence of transmission delay. CONSTITUTION: A CBP(Coexistence Beacon Protocol) transmitter generates a time random number and a frequency random number(303). If it is not an indication time of the time random number, the CBP transmitter confirms the reception of a competition beacon of another WRAN(Wireless Regional Area Network)(305,307). If the competition beacon of another WRAN is not received, the CBP transmitter confirms the termination of the first symbol interval of an SCW(Self-Coexistence Window) slot(309). If the competition beacon received through a sub channel does not exist, the CBP transmitter transmits a CBP packet(315,317).
