LTE, LTE-Advanced and WiMAX: Towards IMT-Advanced Networks

Book Overview

This book is about IMT-Advanced access networks. It begins with two introductory chapters. This chapter provides a brief history and motivation for IMT-Advanced networks, and establishes the requirements for IMT-Advanced networks—as set by the ITU-R. The next chapter, Chapter 2, introduces the physical layer technologies and networking advances that are collectively enabling both IEEE and 3GPP to satisfy the IUT-R requirements in their IMT-Advancements, respectively the IEEE 802.16m amendment and 3GPP'S Release 10. The chapter covers the multi-carrier access technologies utilized in IMT-Advanced networks and their immediate predecessors, including OFDMA and SC-FDMA. It also reviews notions of diversity, adaptive modulation and coding, and frequency reuse, in addition to how wideband transmissions (<20 MHz) are made possible using carrier aggregation techniques. Advanced antenna techniques, including MIMO, CoMP, and inter-cell MIMO are also introduced. Finally, the chapter discusses the use of small cells through wireless multihop relaying and femtocells, in addition to access composites will be utilized in IMT-Advanced networks.

The remainder of the book is divided into three parts. The first discusses WiMAX or IEEE 802.16 networks based on the amalgamated IEEE 802.16-2009 documents, which includes the IEEE 802.16j amendment for multihop relay WiMAX networks, in addition to the IEEE 802.16m amendment. The second Part discusses LTE and LTE-Advanced documents based ...
