This paper investigates spectrum resource coordination for the mixed macrocell and femtocell deployment. Though sharing spectrum provides larger bandwidth for both macrocell and femtocell, cross-tier interferences exist and become drawbacks for them to achieve higher capacities. After analyzing the interferences when using shared spectrum, we propose to employ hybrid spectrum sharing with respect to different femtocells such that the merit of sharing spectrum can be kept and the major interferences can be reduced. Then, we present a method to mitigate the remaining interference when employing hybrid spectrum sharing. Performance evaluation is given to justify our proposed approach on improving overall spectrum utilization.
