摘要：
Device-to-device (D2D) communication can realize the direct communication between mobile users with short distance. It is an enabling technology for realizing Internet of Things in the long-term evolution-advanced system to the future fifth-generation mobile communication system. D2D communication multiplexes the licensed spectrum of cellular users (CUs) to D2D users (DUs) to improve resource utilization of cellular networks. In this paper, a cross-cell fractional frequency reuse-based frequency resource multiplexing (CFRM) scheme is proposed for the multicell D2D communication. In the proposed CFRM, each cell is first divided into two regions, and each region is allocated different spectrum resources to reduce the interference between neighboring cells. Then, the uplink resources of CUs are partially multiplexed by DUs, which can decrease the interference of the DUs to the CUs. The simulation results show that CFRM can reduce the interference, guarantee the quality of service of CUs, and increase the throughput of cellular networks.
