D2D (Device-to-Device) communication underlaying cellular network has received much attention to utilize cellular resources in a more efficient way. Since the range of
D2D communication is expected to be shorter than cell range, there are potential advantages such as reducing delay, reducing the number of hops, improving resource efficiency, and offloading cellular traffic. In this thesis, a new resource selection scheme for D2D communication is proposed and new concepts are introduced. In addition, We focus on new cellular environment, Semi-Persistent Scheduling (SPS) based cellular network, which is never considered in existing papers. We claim that D2D communication in SPS based cellular network has strength with respect to overhead compared to D2D communication in Dynamic Scheduling (DS) based cellular network. Therefore, D2D communicataion in SPS based cellular network can be more efficient. In
particular, SPS is considered one of possible scheduling methods since it is a suitable scheduling method for VoLTE (Voice over IP on top of LTE) packets. In the simulation, we verify that D2D communication in SPS based cellular network achieves better performance
in terms of achievable bits per the number of signaling messages for D2D communication. In addition, we also verify that D2D communication in SPS based cellular network is more efficient to maintain the peformance of cellular network.
