Liying Li, Guodong Zhao, Sihua Lin, Zhi Chen · 2018
Co-channel interference is one of the most important issue in cache-enabled device-to-device (D2D) wireless networks. In this paper, we propose a D2D link scheduling algorithm to manage the interference, called Max-SIR scheduling algorithm. It consists of two steps, i.e., link scheduling and link removal. In the algorithm, D2D links are scheduled with the maximum signal-to-interference ratios (SIRs) considering the co-channel interference in a cell. Simulation results show that the proposed algorithm outperforms the existing ones in terms of the system throughput and the number of scheduled D2D links.
