WINNER Spectrum Sharing with Fixed Satellite Services

The IST 6^th framework WINNER project defines spectrum sharing techniques for future wireless communication systems. This paper addresses spectrum sharing capabilities between different radio technologies. More particularly, spectrum sharing between WINNER system and the Fixed Satellite Service (FSS) community is at stake. The goal is to efficiently share the spectrum without causing harmful interference towards the primary system (i.e., FSS). A power assignment mechanism for the coexistence is proposed where different power levels are assigned in the cellular network in the areas surrounding the FSS system. Simulation results for the coexistence between both systems is carried out where the spectrum used by the WINNER system is punctured for the transmission of the primary FSS system. Finally, the results show that spectrum utilization is significantly improved.
