It was only a few years ago that “ubiquitous connectivity” was recognized as the future of wireless communication systems. In the era of ubiquitous connectivity, it was expected that the broadband mobile Internet experience would be pervasive, and seamless connectivity on a global scale would be no surprise at all. The quality of service would be guaranteed no matter when/where/what the users wanted with the connectivity. Connectivity would even be extended to object-to-object communication, where no human intervention was required. All objects would become capable of autonomous communication.

LTE-Advanced becomes a truly global standard for 4G cellular communications. Relay, as one of the key technologies of LTE-Advanced, can significantly extend the coverage, and improve the system throughput. LTE-A standards and tech- nologies were described in several recent books where the limited pages for relay feature prevent the detailed explanations of the technology. In this book, we tried to provide an in-depth description of LTE-A relay development. More specifically, significant portions are spent on relay channel modeling and potential technologies during the study item phase of the development, although some of those tech- nologies, such as Type 2 cooperative relay, multi-hop relay, relay with backhaul of carrier aggregation, were not standardized in Release 10 LTE.

In this first part of the book the Vienna Link Level (LL) Simulators are described. The first chapter provides basics of LL simulations, introduces the most common variables and parameters as well as the transceiver structures that are applied in Long-Term Evolution (LTE) and Long-Term Evolution-Advanced (LTEA). We focus here mostly on the Downlink (DL) of LTE as most results reported in later chapters are related to DL transmissions.

Wireless technologies like GSM, UMTS, LTE, Wireless LAN and Bluetooth have revolutionized the way we communicate by making services like telephony and Internet access available anytime and from almost anywhere. Today, a great variety of technical publications offer background information about these technologies but they all fall short in one way or another. Books covering these technologies usually describe only one of the systems in detail and are generally too complex as a first introduction. The Internet is also a good source, but the articles one finds are usually too short and super- ficial or only deal with a specific mechanism of one of the systems. For this reason, it was difficult for me to recommend a single publication to students in my telecommunication classes, which I have been teaching in addition to my work in the wireless telecommunication industry. This book aims to change this.

This books attempts to provide an extensive overview on Long-Term Evolution (LTE) networks. Understanding LTE and its Performance is purposely written to appeal to a broad audience and to be of value to anyone who is interested in 3GPP LTE or wireless broadband networks more generally. The aim of this book is to offer comprehensive coverage of current state-of-the-art theoretical and techno- logical aspects of broadband mobile and wireless networks focusing on LTE. The presentation starts from basic principles and proceeds smoothly to most advanced topics. Provided schemes are developed and oriented in the context of very actual closed standards, the 3 GPPP LTE.
