TLDR
In this article, the authors summarize the 5G mobile communication requirements and challenges and present a potential step change for the evolution toward 5G, which shows that macro-local coexisting and coordinating paths will replace one macrodominated path as in 4G and before.Abstract:
In this article, we summarize the 5G mobile communication requirements and challenges. First, essential requirements for 5G are pointed out, including higher traffic volume, indoor or hotspot traffic, and spectrum, energy, and cost efficiency. Along with these changes of requirements, we present a potential step change for the evolution toward 5G, which shows that macro-local coexisting and coordinating paths will replace one macro-dominated path as in 4G and before. We hereafter discuss emerging technologies for 5G within international mobile telecommunications. Challenges and directions in hardware, including integrated circuits and passive components, are also discussed. Finally, a whole picture for the evolution to 5G is predicted and presented.read more

Energy-Efficient Resource Allocation in Cellular Networks With Shared Full-Duplex Relaying
TL;DR: This work considers a shared FDR deployment scenario, where an FDR relay is deployed at the intersection of several adjacent cell sectors and uses Dinkelbach and discrete stochastic optimization methods to solve the energy-efficient resource-allocation problem efficiently.

Self-Organized Relay Selection for Cooperative Transmission in Vehicular Ad-Hoc Networks
TL;DR: This paper maps the self-interest-driven relay selection decision-making problem to an automata game formulation and presents a noncooperative game-theoretic analysis, and shows that the relay selection game is an ordinal potential game.
