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

Verification of Configuration Management Changes in Self-Organizing Networks
TL;DR: The approach makes use of constraint optimization techniques to resolve collisions as well as find the appropriate order for deploying undo requests, and uses a minimum spanning tree-based clustering technique to eliminate false positive collisions.

Quantization Design and Channel Estimation for Massive MIMO Systems with One-Bit ADCs
TL;DR: Simulation results show that the proposed adaptive quantization (AQ) and RQ schemes, owing to their wisely devised thresholds, present a significant performance improvement over the conventional fixed quantization scheme that uses a fixed threshold, and meanwhile achieve a substantial training overhead reduction for channel estimation.

Fabrizio Tamburini,Elettra Mari,Anna Sponselli,Bo Thid,Bo Thid,Antonio Bianchini,Filippo Romanato +6 more
TL;DR: In this paper, it was shown experimentally that two beams of incoherent radio waves, transmitted on the same frequency but encoded in two different orbital angular momentum states, can simultaneously transmit two independent radio channels.
