Preface

In the nineteenth century, scientists, mathematician, engineers and innovators started investigating electromagnetism. The theory that underpins wireless communications was formed by Maxwell. Early demonstrations took place by Hertz, Tesla and others. Marconi demonstrated the first wireless transmission. Since then, the range of applications has expanded at an immense rate, together with the underpinning technology. The rate of development has been incredible and today the level of technical and commercial maturity is very high. This success would not have been possible without understanding radio-wave propagation. This knowledge enables us to design successful systems and networks, together with waveforms, antennal and transceiver architectures. The radio channel is the cornerstone to the operation of any wireless system.

Today, mobile networks support millions of users and applications spanning voice, email, text messages, video and even 3G images. The networks often encompass a range of wireless technologies and frequencies all operational in very diverse environments. Examples are: Bluetooth personal communications that may be outside, indoors or in a vehicle; wireless LAN in buildings, femtocell, microcell and macrocell sites; wireless back-haul; and satellite communications. Examples of emerging wireless technologies include body area networks for medical or sensor applications; ultra wideband for extremely high data rate communications and cognitive radio to support efficient and effective use of unused sections of the electromagnetic spectrum.

Mobile device usage continues to grow with no decrease in traffic flow. Most of the current cellular networks are now in their third generation (3G). Based on Universal Mobile Telecommunication System (UMTS) or Code Division Multiple Access (CDMA), they support data rates of a few megabits per second under low-mobility conditions. During the last few years, the number of cell phones has dramatically increased as wireless phones have become the preferred mode of communication, while landline access has decreased. Moreover, most new wireless devices like smart phones, tablets and laptops include 3G capabilities. That is why new applications are proposed every year and it is now common to use mobile devices not only for voice but also for data, video, and so on.

The direct consequence of this is that the amount of wireless data that cellular networks must support is exploding. For instance, Cisco recently noted in its Visual Networking Index (VNI) Global Mobile Data Forecast that a smart phone generates, on average, 24 times more wireless data than a plain vanilla cell phone. The report also noted that a tablet generates 122 times more wireless data than a feature phone, and a wireless laptop creates 515 times the wireless data traffic of traditional cell phones. Hence in 2009, the International Telecommunication Union—Radiocommunication Sector (ITU-R) organization specified the International Mobile Telecommunication Advanced (IMT-A) requirements for 4G standards, setting peak speed requirements for 4G service at 100 Mbit/s for high mobility communication (such as from trains and cars) and 1 Gbit/s for low mobility communication (such as pedestrians and stationary users). The main candidate to 4G is the so called Long Term Evolution Advanced which is expected to be released in 2012. Unlike the first Long Term Evolution (LTE) deployments (Rel 8 or Rel 9) which do not fully meet the 4G requirements, LTE-Advanced is supposed to surpass these requirements. That is why LTE-Advanced and beyond networks introduce new technologies and techniques (Multiple antennas, larger bandwidth, OFDMA, and so on) whose aim is to help reach very high capacity even in mobility conditions. 4G and beyond network are not deployed yet, however most of industry and researchers focus on developing new products, algorithms, solutions and applications. Like all wireless networks the performance of 4G and beyond networks depend for a major part on the channel, that is, how the signal propagates between emitters and users. That is why channel modelling and propagation, which is sometimes seen as an old topic, is very important and must have full consideration. Indeed, in order to study the performance of future wireless networks, it is very important to be able to characterize the wireless channel into different scenarios and and to be able to take into account the new situations introduced by future networks such as multiple antennas that can be embedded in high speed cars or worn directly on the body.

Propagation and Channel Models

This book presents an overview of models of how the channel will behave in different scenarios, and how to use these channel models to study the performance of 4G and beyond networks. 4G is imminent, so we believe it is good timing to have a book on channel propagation for these aspects. Moreover, future wireless networks will never stop using larger bandwidth, higher frequencies, more antennas, so this book is not only focused on 4G but on beyond 4G networks as well, where new concepts like cognitive radio or heterogeneous will be ever more important.

This book is divided into three parts as follows:

That is why Chapter 13 focuses on the use of channel models for performing system level simulations. In more detail it focuses on the IMT-Advanced model which is the model proposed by 3GPP for LTE-Advanced. If software solutions can be a good way to simulate the channel, another alternative is to use channel emulators. Those will be investigated in Chapter 14. For all the channels presented in this book, it is important to consider how to perform measurement and calibratethe models accurately. If most of the chapters present results based on measurements, Chapter 15 focuses on over the air MIMO measurement, which is the most challenging type of measurement and is currently highly regarded by many researchers because multi-user MIMO is a key technology in 4G and beyond networks. Then, Chapter 16 presents different topics related to cognitive radio, which will also play a strong role in future communication systems. If there is one important consideration when studying the performance, it is to take into account the antenna aspects which have a strong interaction with the radio channel. That is why the two last chapters will present the antenna aspects related to future networks. First Chapter 17 will present all the challenges when designing small antennas for a LTE-A system. Finally, Chapter 18 will focus on antennas for BANs and more especially how to perform statistical characterization of antennas in such an environment.

Enabling Technologies for 3GPP LTE-Advanced Networks

Narcis Cardona, Jose F. Monserrat and Jorge Cabrejas

Universitat Politècnica de València, Spain

The specifications of Long Term Evolution (LTE) in 3rd Generation Partnership Project (3GPP) (Release 8) were just finished when work began on the new Long Term Evolution Advanced (LTE-A) standard (Release 9 and beyond). LTE-A meets or exceeds the requirements imposed by International Telecommunication Union (ITU) to Fourth Generation (4G) mobile systems, also called International Mobile Telecommunication Advanced (IMT-A). These requirements were unthinkable a few years ago, but are now a reality. Peak data rates of 1 Gbps with bandwidths of 100 MHz for the downlink, very low latency, more efficient interference management and operational cost reduction are clear examples of why LTE-A is so appealing for operators. Moreover, the quality breakthrough affects not only operators but also end users, who are going to experience standards of quality similar to optical fiber. To reach these levels of capacity and quality, the international scientific community, in particular the 3GPP, are developing different technological enhancements on LTE. The most important technological proposals for LTE-A are: support of wider bandwidth (carrier aggregation), advanced Multiple Input Multiple Output (MIMO) techniques, Coordinated Multipoint transmission or reception (CoMP), relaying, enhancements for Home eNodeB (HeNB) and machine-type communications. To analyze both the context of LTE-A and the new enabling technologies, this chapter is divided as follows:

1.1 Introduction

Along its standardization LTE was designed as an evolution of legacy Third Generation (3G) mobile systems due to the incorporation of a set of technological improvements, such as:

All these new features represent a qualitative and quantitative leap in system performance that is motivated by different reasons. Market globalization and liberalization and the increasing competence among vendors and operators coming from this new framework has led to the emergence of new technologies. This fact comes together with the popularization of Institute of Electrical & Electronics Engineers (IEEE) 802 technologies within the mobile communications sector. Finally, end users are becoming more discerning and demand new and better services such as Voice over IP (VoIP), video-conference, Push-to-talk over Cellular (PoC), multimedia messaging, multiplayer games, audio and video streaming, content download of ring tones, video clips, virtual private network connections, web browsing, email access, file transfer, and so on. It is precisely this increasing market demand and its enormous economic benefits, together with the new challenges that come with the requirements in higher spectral efficiency and services aggregation that raised the need to allocate new frequency channels to mobile communications systems. That is why the International Telecommunication Union—Radiocommunication Sector (ITU-R) WP 8F started in October 2005 the definition of the future 4G, also known as IMT-A, following the same model of global standardization used with 3G systems. The objective of IMT-A is to specify a set of requirements in terms of transmission capacity and quality of service, in such a way that if a certain technology fulfils all these requirements it is included by the ITU in the IMT-A set of standards. This inclusion firstly endorses technologies and motivates operators to invest in them, but furthermore it allows these standards to make use of the frequency bands specially designated for IMT-A, which entails a great motivation for mobile operators to increase their offered services and transmission capacity. Given this economic outlook, the 3GPP established the LTE standardization activity as an ongoing task to build up a framework for the evolution of the 3GPP radio technologies, concretely Universal Mobile Telecommunication System (UMTS), towards 4G. The 3GPP divided this work into two phases: the former concerns the completion of the first LTE standard (Release 8), whereas the latter intends to adapt LTE to the requirements of 4G through the specification of a new technology called LTE-A (from Release 9 on). Following this plan, the LTE-A Study Item was launched in April 2008 to analyze IMT-A requirements and pose conditions to the new standard:

1.2 General IMT-Advanced Features and Requirements

IMT-A systems comprise new capabilities and new services, migrating towards an all-IP network. As happened with the IMT-2000 family of standards, it is expected that IMT-A becomes, through a continuous evolution, the dominant technology designed to support new applications, products and services. Moreover, IMT-A systems must support applications for both low and high speed mobility and for different data rates. The main characteristics of IMT-A systems are:

Requirements established by ITU-R can be classified in three main categories: services, spectrum and technical aspects. The aim of these requirements is not to limit the performance of the candidate technologies, but to ensure that the IMT-A radio interface technologies fulfil these minimum conditions to become a member of the 4G family of standards.
