Abstract
In this paper, we study the link scheduling problem in cache-enabled device-to-device (D2D) wireless networks considering the quality-of-service (QoS) requirement of each scheduled D2D link. We propose a segment-based link scheduling method which consists of two phases, user pairing and link scheduling, to maximize the overall system throughput. We designed a segment factor to control interference among the established D2D links in the link scheduling phase. With the proposed method, interference among different scheduled D2D links can be significantly reduced and the QoS of each link can be guaranteed. Simulation results show that the proposed method outperforms the existing ones in terms of overall system throughput and the number of scheduled D2D links.
