Joint power and reduced spectral leakage-based resource allocation for D2D communications in 5G
Résumé
This paper proposes a joint mode selection and resource block (RB) allocation for the direct device-to-device (D2D) communication underlying cellular network. Universal-filtered multi-carrier (UFMC) technique which is considered as a potential candidate for the future communication systems due to its robustness against intercarrier interference (ICI), is introduced for D2D communication. In this paper, our goal is to design a network that selects the transmission mode between D2D and traditional cellular transmission mode. Unlike existing work on the mode selection which focused on network performance to improve overall throughput and providing required quality-of-service (QoS) for cellular users (CUs), we study the interference from the other D2D links operating on the edge of the neighboring cells. D2D communications provide a reliable transmission near edge of the cells but is limited by interference from CUs as well as D2D pairs belong to edge of the neighboring cells. We present an approach in UFMC-based D2D scenario to reduce the spectral leakage to nearby RBs used for same or other D2D links. Further, we develop an optimization framework that aims to maximize signal-to-interference-and-noise ratio (SINR) and improves the overall throughput
