摘要: Device-to-Device (D2D) communications potentially can improve spectrum efficiency because of resource spatial reuse. In this paper, we consider a central-controlled D2D architecture, in which a cellular operator can decide whether mobile devices can connect to each other directly. We aim to maximize system throughput while also achieve fairness in resource allocation. A resource scheduling algorithm that dynamically adjusts the boundary of resource-assignment area and resource-contention area is proposed. Also, criteria to extract spatial reuse gain and meet proportional fair (PF) metric are determined. Simulation results show that the proposed algorithm can increase system throughput by exploring spatial reuse gain and maintain good proportional fairness among D2D communication pairs.
