Device-to-device (D2D) communication has been recently proposed to mitigate the burden of base stations by leveraging the underutilized cellular spectrum resources, where high overall network throughput and D2D access rate are critical for its service performance and availability. In this paper, we study the resource allocation problem to push the limit of D2D communication underlaying cellular networks...
Device-to-device (D2D) communication is a promising technology for 5G wireless communication system. Since D2D communication usually reuses the resource of cellular users, interference management and resource allocation of D2D are the mainly research directions in D2D communication underlay cellular networks. The physical-layer security problem of D2D link is rarely under studied. In this paper, we...
Femtocells have attracted more and more attention in academia, industry and standardization forums. Besides, energy efficiency has been widely discussed in recent years. However, most of the existing works focus on the energy efficiency of macro base stations, the energy efficiency of femto base stations is neglected. In this paper, we study the maximization of energy efficiency of downlink OFDMA...
