Standardization activities have already begun on 5G to support very high system requirements. A common consensus toward achieving these targets is to permit transmission over a wide spectrum range. The departure from a dedicated licensed-only spectrum regime to a shared spectrum model poses new challenges for next generation mobile communication systems. Cognitive Radio Technologies is an enabler...
In currently deployed wireless networks, the lack of dynamic control across wireless resources leads to suboptimized and unbalanced spectrum loads, especially in below 6GHz bands, which in turn creates a (perceived) capacity bottleneck in end users. This issue can be addressed through the adoption of the eDSA (extended Dynamic Spectrum Access) paradigm, which consists of enhanced resource management...
This paper presents the vision and some early results achieved by the EU-funded SPEED-5G project which is part of 5G PPP [1]. It addresses some key challenges of future 5G systems, i.e. a 1000 times higher capacity, a much lower latency and a much improved user quality of experience compared to currently deployed networks. The devised new technologies are based on densification of small cells, exploitation...
The articles in this special section that focuses on the development and applications supported by fifth generation (5G) next generation networking. During the summer and autumn of 2014, the Wireless World Research Forum (WWRF) was involved in a wide range of activities related mostly to progressing the global discussion on the development of fifth-generation(5G) concepts. Most significantly, on 22–23...
