A reliable and focused treatment of the emergent technology of fifth generation (5G) networks

This book provides an understanding of the most recent developments in 5G, from both theoretical and industrial perspectives. It identifies and discusses technical challenges and recent results related to improving capacity and spectral efficiency on the radio interface side, and operations management on the core network side. It covers both existing network technologies and those currently in development in three major areas of 5G: spectrum extension, spatial spectrum utilization, and core network and network topology management. It explores new spectrum opportunities; the capability of radio access technology; and the operation of network infrastructure and heterogeneous QoE provisioning.

5G Networks: Fundamental Requirements, Enabling Technologies, and Operations Management is split into five sections: Physical Layer for 5G Radio Interface Technologies; Radio Access Technology for 5G Networks; 5G Network Interworking and Core Network Advancements; Vertical 5G Applications; and R&D and 5G Standardization. It starts by introducing emerging technologies in 5G software, hardware, and management aspects before moving on to cover waveform design for 5G and beyond; code design for multi-user MIMO; network slicing for 5G networks; machine type communication in the 5G era; provisioning unlicensed LAA interface for smart grid applications; moving toward all-IT 5G end-to-end infrastructure; and more. This valuable resource:

• Provides a comprehensive reference for all layers of 5G networks
• Focuses on fundamental issues in an easy language that is understandable by a wide audience
• Includes both beginner and advanced examples at the end of each section
• Features sections on major open research challenges

5G Networks: Fundamental Requirements, Enabling Technologies, and Operations Management is an excellent book for graduate students, academic researchers, and industry professionals, involved in 5G technology.

1.1 Introduction

As the number of smartphones and demand for higher data-rate connections keep explosively growing, the technology has to pursue this trend in order to be able to provide the suitable communication schemes. By 2020, it is calculated that the total global mobile wireless user devices will be over 10 billion, with the mobile data traffic growing more than 200 times over compared to 2010 numbers. It is foreseeable that 4G mobile communication system could no longer meet the need of users service requirements. Thus, the new 5G communication systems are promising a complete network structure with unlimited access to information, providing the requested service demands to users far beyond what the current 4G offers by supporting innovative new wireless technologies and network architecture to meet the extremely high-performance requirement (Table 1.1).

Table 1.1 Main comparison between 5G and previous generations

5G	4G and Earlier
New waveforms based on filter banks and other novel technologies	Waveforms based mainly on OFDM and variations
Gbps performance	Up to hundreds Mbps
End-to-end latency of some milliseconds	End-to-end latency of hundreds of milliseconds
Support of massive MIMO	SISO and limited MIMO technologies
Support of mm-wave bands up to hundreds GHz	Operation mainly below 6 GHz bands
Efficient support of massive number of devices in ultradense environments	Support of limited number of devices in dense/congested areas

These features include support for new types and massive number of devices, for very high mobile traffic volumes, universal access for users, very high frequency reuse and spectrum reuse in wireless technologies, automated provisioning, configuration and management of a wide range of new network services, ultrareliable, ultralow latency, ultradensification, and even more. 5G networks would be a heterogeneous networks (HetNets), meaning that different networks will be integrated all together to a unified system, enabling aggregation of multiple existing radio access technologies (RATs) such as LTE-A, Wi-Fi, D2D, and even lightly licensed. Delivering all 5G requirements in order to support the new features and services, a substantial change on the network architecture is inevitable.

Normally, in the past such a process would need deployment of specialized devices build for a specific application and with fixed functionalities. Thus, any development and transformation to follow the constantly increasing and heterogeneous market requirements demands a huge investment to change/deploy hardware. Nowadays, various technologies and architectures have been utilized in order to solve this problem and provide a faster introduction and adaptation of new technologies to the communications systems. One of these elements that offers reprogrammability of the network elements in order to solve new problems or to establish new more suitable functions is software defined networking (SDN). This architecture provides dynamic, manageable, cost-effective, and adaptable solutions, making it ideal for the high-bandwidth, dynamic nature of today's applications. SDN decouples the dependence of implementing instructions that are provided by multiple, vendor-specific devices and protocols, making it bound to an exact hardware. Such aspects are also related to the flexible deployment of functionality to hardware, software, or mixed. As Section 1.3 proposes, hardware has better execution performance, but software offers greater flexibility.
