A timely addition to the understanding of IMT-Advanced, this book places particular emphasis on the new areas which IMT-Advanced technologies rely on compared with their predecessors. These latest areas include Radio Resource Management, Carrier Aggregation, improved MIMO support and Relaying. Each technique is thoroughly described and illustrated before being surveyed in context of the LTE-Advanced standards. The book also presents state-of-the-art information on the different aspects of the work of standardization bodies (such as 3GPP and IEEE), making global links between them. Explores the latest research innovations to assess the future of the LTE standard Covers the latest research techniques for beyond IMT-Advanced such as Coordinated multi-point systems (CoMP), Network Coding, Device-to-Device and Spectrum Sharing Contains key information for researchers from academia and industry, engineers, regulators and decision makers working on LTE-Advanced and beyond

This book offers a timely reflection on how the proliferation of advanced wireless communications technologies, particularly cognitive radio (CR) can be enabled by thoroughly-considered policy and appropriate regulation. It looks at the prospects of CR from the divergent standpoints of technological development and economic market reality. The book provides a broad survey of various techno-economic and policy aspects of CR development and provides the reader with an understanding of the complexities involved as well as a toolbox of possible solutions to enable the evolutionary leap towards successful implementation of disruptive CR technology or indeed any other novel wireless technologies. Cognitive Radio Policy and Regulation showcases the original ideas and concepts introduced into the field of CR and dynamic spectrum access policy over nearly four years of work within COST Action IC0905 TERRA, a think-tank with participants from more than 20 countries. The book’s subject matter includes: • deployment scenarios for CR; • technical approaches for improved spectrum sharing; • economic aspects of CR policy and regulation; • impact assessment of cognitive and software-defined radio; and • novel approaches to spectrum policy and regulation for the age of CR. The book will interest researchers in the field of wireless communications, especially those working with standardization and policy issues, as well as industry and regulatory professionals concerned with radio spectrum management and the general development of wireless communications. Considerable complementary reference material such as power point slides and technical reports that illustrates and expands on the contents of the book is provided on the companion website to the book, found at http://www.cost-terra.org/CR-policy-book

The use of radio-frequency communication-commonly referred to as wireless communication-is becoming more pervasive as well as more economically and socially important. Technological progress over many decades has enabled the deployment of several successive generations of cellular telephone technology, which is now used by many billions of people worldwide; the near-universal addition of wireless local area networking to personal computers; and a proliferation of actual and proposed uses of wireless communications. The flood of new technologies, applications, and markets has also opened up opportunities for examining and adjusting the policy framework that currently governs the management and use of the spectrum and the institutions involved in it, and models for allocating spectrum and charging for it have come under increasing scrutiny. Yet even as many agree that further change to the policy framework is needed, there is debate about precisely how the overall framework should be changed, what trajectory its evolution should follow, and how dramatic or rapid the change should be. Many groups have opinions, positions, demands, and desires related to these questions-reflecting multiple commercial, social, and political agendas and a mix of technical, economic, and social perspectives. The development of technologies and associated policy and regulatory regimes are often closely coupled, an interplay apparent as early as the 1910s, when spectrum policy emerged in response to the growth of radio communications. As outlined in this report, current and ongoing technological advances suggest the need for a careful reassessment of the assumptions that inform spectrum policy in the United States today. This book seeks to shine a spotlight on 21st-century technology trends and to outline the implications of emerging technologies for spectrum management in ways that the committee hopes will be useful to those setting future spectrum policy.

Radio Technologies and Concepts for IMT-Advanced presents the findings of the Wireless World Initiative New Radio (WINNER) project in Framework Program 6 of the European Commission. It provides an insight into the key concepts and technologies for the IMT-Advanced radio interface, based on the collaborative research of manufacturers, network operators, research centres and universities within WINNER. The book covers the fundamental radio characteristics of a typical 4G wireless communication system, focusing on the transceiver’s chain from the physical layer to layers 2 and 3. Starting by defining realistic and futuristic usage scenarios, the authors provide in-depth discussion of key technologies including modulation and coding, link level procedures, spatial-temporal processing, multiple access schemes and inter-cell interference mitigation, channel estimation and newly developed channel models. Finally, a cost assessment and optimisation methodology is developed for different deployment concepts in order to assess a wireless system in a condition close to reality. The book provides an important system-level approach to the latest radio technologies in the field, and evaluates IMT-Advanced research in relation to international standardisation. Presents the research findings of IMT-Advanced radio interface from the WINNER project Covers the latest concepts for relaying, multiple access, radio resource control, flexible spectrum use, and ITU-R spectrum demand calculation Examines the most recent Multiple-Input, Multiple-Output (MIMO) techniques, and Distributed Antenna Systems (Coordinated Multipoint Transmissions) Describes a 4G system concept and all major building blocks Provides 4G propagation models and system-level evaluation methodologies

In 2003, the Department of Commerce's Spectrum Policy Initiative was established with the objective of promoting a more efficient and beneficial use of the spectrum. As part of that Initiative, a series of public forums about spectrum management policy was held. The Computer Science and Telecommunications Board was asked to organize one of these forums, a public forum to gather the views of a variety of government and private sector stakeholders about the impact of spectrum policy on their activities. This report presents a summary of those views. Among those included are those representing national defense, homeland security, aviation, science, public safety, amateur radio, cellular voice and data, and terrestrial broadcast uses of the spectrum. Although prepared by the NRC, the report does not present NRC findings or recommendations. A broader study of spectrum policy, including findings and recommendations, will be issued in early 2005.
