Considering current trends, the need for more sophisticated bandwidth-intensive services will further push the limits on future standards to provide integration between wireless technologies and higher speeds, requiring a new generation of mobile networks, the so-called fifth generation (5G). Advanced technologies such as massive MIMO and millimeter-wave systems will have significant impact on ...

The growing demand for mobile Internet, and the increasing number of connected devices, has required significant advancements in radio technology and networks compared to the previous generations of mobile telecommunication. Security however has only seen incremental changes to the previous mobile telecommunication generation, with enhancements that mitigate new threats and address revealed wea...

There have been active research activities worldwide in developing the next-generation 5G wireless network. The 5G network is expected to support significantly large amount of mobile data traffic and huge number of wireless connections, achieve better costand energy-efficiency as well as quality of service (QoS) in terms of communication delay, reliability and security. To this end, the 5G wire...

In the Fifth generation (5G) wireless communication systems, a majority of the traffic demands is contributed by various multimedia applications. To support the future 5G multimedia communication systems, the massive multiple-input multiple-output (MIMO) technique is recognized as a key enabler due to its high spectral efficiency. The massive antennas and radio frequency (RF) chains not only im...

5G has to fulfill the requirements of ultra-dense, scalable, and customizable networks such as IoT while increasing spectrum and energy efficiency. Given the diversity of envisaged applications and scenarios, one crucial property for 5G New Radio (NR) is flexibility: flexible UL/DL allocation, bandwidths, or scalable transmission time interval, and most importantly operation at different freque...

As the cellular technology is growing at a rapid pace, users always seek for a set of appropriate packages all together, including all the current features in use. Hence, the search for a new technology is always the main concern of the foremost cell phone companies to out innovate their competitors. The main purpose of the fifth generation wireless technology (5G) is formulated to design the u...

Exponential increase in mobile video delivery will continue with the demand for higher resolution, multi-view and large-scale multicast video services. Novel fifth generation (5G) 3GPP New Radio (NR) standard will bring a number of new opportunities for optimizing video delivery across both 5G core and radio access network. One of the promising approaches for video quality adaptation, throughpu...

The purpose of this paper is to take a step toward clarifying what '5G' really means in the technological sense, by: reducing 5G to its fundamental core (including acknowledging what it is arguably not); expanding on some of the use case scenarios that 5G might enable; and discussing conceivable implications for operators in terms of network infrastructure and commercial opportunities. This can...

There is a wide consensus by the research community and the industry that it will not be possible to satisfy future mobile traffic demand and applications’ requirements by simply evolving the current 4G architecture. Instead, there is the need for a considerable revision of the mobile network system: such an effort is commonly referred to as the future “5G architecture”, and large-scale initiat...

This paper presents the control and data plane architecture design for a 5G transport solution (5G-Crosshaul) with the aim of integrating the fronthaul and backhaul network segments in a common transport stratum. The control plane relies on the SDN/NFV concept to control and orchestrate the different elements of the network (the 5G-Crosshaul Control Infrastructure, XCI). The data plane is based...
