Abstract: Today's radio frequency regulation is undergoing fundamental changes. There is a high demand for radio frequency spectrum for data communication but no blank spots in the frequency assignments plan. Under the approach of coexistence and cognitive radio multiple systems can share spectrum in unlicensed bands. Additionally non-exclusive licensing allowing secondary systems to occupy spectrum if the primary license holder is absent are emerging. In this case multiple systems can compete for spectrum access. In this paper we present an approach how two IEEE 802.16 systems can coexist in the same frequency band. The basic approach is to define rules how the systems can schedule their transmissions to provide spectrum opportunities for each other. The key idea is to have one system transmit at the beginning and the other at the end of each frame. Analytic and simulation results are presented showing how systems can estimate available capacity and the impact of their behaviour to own and overall performance.
