FIELD: radio engineering, communication.SUBSTANCE: invention relates to communication engineering and can be used in wireless communication systems. Provided are an apparatus and a method for operation of a coexistence beacon protocol (CBP) packet sender in a cognitive radio (CR)-based system. The method includes identifying a self-coexistence window (SCW) regular pattern of neighbouring wireless regional area networks (WRAN), if vacant SCW slots are not periodically occurring, selecting a WRAN as a contender among the neighbouring WRAN, performing a contention for transmitting the CBP packet with the contender within SCW slots that are occupied by the WRAN, and configuring an SCW usage pattern so that an SCW usage period of the CBP packet sender is double that of an SCW usage period of the contender when winning in the contention.EFFECT: high throughput of transmission channels.38 cl, 13 dwg, 1 tbl |
