5G 2015 - International Workshop on Cognitive Radio for 5G Networks

The exponential growth of wireless data traffic urged the international wireless industries and academia to lay out a new wireless network standard which is 5G. It is generally believed that the future 5G network may need to be engineered to meet a multitude of stringent requirements in terms of cost, energy and spectral efficiency, number of connected devices and latency. Cognitive Radio (CR) is one of the promising techniques to meet these requirements by exploiting underutilized spectrum bands especially at microwave frequencies where there is a spectrum crunch. CR has applications ranging from the traditional cellular to device-to-device (D2D) and vehicle-to-vehicle (V2V) communication systems via interweave, underlay and overlay dynamic spectrum access. In cellular systems, CR can enhance the overall efficiency of the network by allowing opportunistic and shared spectrum access. And for the D2D systems, massive short range connectivity which facilitates efficient data transfer is realized using CR. On the other hand, network assisted CR techniques can be leveraged in vehicular applications, such as driverless cars, learning the road traffic which consequently contribute in achieving the zero accident goal of the future intelligent transport systems (ITS). Furthermore, for multi-tier heterogeneous network (HetNet), CR can be utilized to opportunistically offload delay tolerant data traffic to different tiers and radio access technologies (RATs) which is one of the effective means to alleviate traffic congestion.
Given the above promising potentials of CR technology, still a number of challenges arise including how to enable autonomous CR transmission without creating significant interference to the primary networks for Machine to Machine (M2M), D2D and HetNet communication systems. This workshop aims to gather researchers, academia, industry and regulators to present and discuss their research findings on the CR technology and, to highlight the opportunities, challenges and potentials of CR for realizing the future 5G network.
