APPARATUS AND METHOD FOR TRANSMITTING COEXISTENCE BEACON PROTOCOL PACKET IN CORGNITIVE RADIO WIRELESS COMMUNICATION SYSTEM

摘要

PURPOSE: An apparatus and a method for transmitting a coexistence beacon protocol(CBP) packet in a recognition wireless communication system are provided to prevent the transmission collision of the CBP packet by transferring the CBP packet through different channels. CONSTITUTION: Priority is applied to each channel by referring the channel state of wireless regional area networks. 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.
