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

Low-complexity PTS PAPR reduction scheme for UFMC systems
TL;DR: Numerical results show that the proposed PTS scheme achieves nearly the same PAPR reduction as that achieved by the conventional PTS scheme; meanwhile, it has considerably low computational complexity when the probability of the maximum peak power being more than the possible minimum peak power is greater than or equal to 0.5.

Small cells on/off control and load balancing for green dense heterogeneous networks
Y. Jin,Ling Qiu,Xiaowen Liang +2 more
TL;DR: A practical suboptimal SCs on/off algorithm with linear computational complexity is developed that achieves a comparable performance, in terms of both the NEE and the network throughput, as the optimal one and outperforms the traditional algorithms.
