Abstract

Device-to-Device (D2D) communication underlying cellular networks has been envisioned as one of the promising mobile communication techniques to offload base stations (BSs) In D2D communication the mode selection problem and the resource management problem both possess a profound impact on determining the system performance Particularly an effective mode selection scheme can greatly improve the total system throughput In classical mode selection schemes the best mode selection scheme referred to as ``capacity-based scheme' is difficult to implement due to the requirement of global channel information in making the mode selection decision To address this issue we propose a low-complexity mode selection scheme which is referred to as maximum reference interference (MRI)-based scheme The proposed MRI-based scheme eliminates the need of global channel information and it effectively reduces the operational complexity by replacing the exact interference value with an upper bound To further reduce severe inter-cell interference and improve the system throughput we propose a dynamic resource partition scheme along with a balanced resource allocation scheme for D2D-enabled cellular networks Simulation results show that MRI scheme not only achieves the comparable throughput performance to the optimal scheme but also effectively reduces power consumption and implementation complexity
