【简 介】:[原版]WCDMA for UMTS - Wiley
【目 录】: Written by leading experts in the field, the first edition of WCDMA for UMTS quickly became established as the best-selling and most highly respected book on the air interface of 3G cellular systems. Fully revised and updated the third edition now covers the key features of 3GPP Release ‘6 ensuring its position as the leading principal resource in this constantly progressing area.
Features new sections on:
--Multicasting MBMS
--End-to-end performance
--WCDMA field measurements
--Smart antenna beamforming in WCDMA
--Enhanced uplink DCH concept - beyond 3GPP Rel'6
--Chinese TD-SCDMA
--An IMS Case Study
The third edition provides a deep understanding of the WCDMA air interface, its capabilities and its optimal usage - the key to success in the UMTS business, making this practical approach highly
accessible to operators, network and terminal manufacturers, service providers, university students and frequency regulators.
Second generation telecommunication systems, such as GSM, enabled voice traffic to go wireless: the number of mobile phones exceeds the number of landline phones and the mobile phone penetration exceeds 80% in countries with the most advanced wireless markets. The data handling capabilities of second generation systems are limited, however, and third generation systems are needed to provide the high bit rate services that enable high quality images and video to be transmitted and received, and to provide access to the web with higher data rates. These third generation mobile communication systems are referred to in this book as UMTS (Universal Mobile Telecommunication System). WCDMA (Wideband Code Division Multiple Access) is the main third generation air interface in the world and deployment has been started in Europe and Asia, including Japan and Korea, in the same frequency band, around 2 GHz. WCDMA will be deployed also in the USA in the US frequency bands. During the writing of this third edition, the largest WCDMA operators have reached the 6 million subscribers milestone and GSM/WCDMA multimode terminals are being sold in more than 50 countries. Though less than 10 million subscribers is still small compared to the GSM subscriber base, the growth rate is expected to follow a similar track to GSM in the early days, and eventually the subscribers currently using PDC or GSM will emigrate to WCDMA as the terminals on offer and service coverage continue to improve. The large market for WCDMA and its flexible multimedia capabilities will create new business opportunities for manufacturers, operators, and the providers of content and applications. This book gives a detailed description of the WCDMA air interface and its utilisation. The contents are summarised in Figure 1. Chapter 1 introduces the third generation air interfaces, the spectrum allocation, the time schedule, and the main
differences from second generation air interfaces. Chapter 2 presents example UMTS applications, concept phones and the quality of service classes. Chapter 3 introduces the principles of the WCDMA air interface, including spreading, Rake receiver, power control and handovers. Chapter 4 presents the background to WCDMA, the global harmonisation process and the standardisation. Chapters 5–7 give a detailed presentation of the WCDMA standard, while Chapters 8–12 cover the utilisation of the standard and its performance.
Chapter 5 describes the architecture of the radio access network, interfaces within the radio
access network between base stations and radio network controllers (RNC), and the interface between the radio access network and the core network. Chapter 6 covers the physical layer (Layer 1), including spreading, modulation, user data and signalling transmission, and the main physical layer procedures of power control, paging, transmission diversity and handover measurements. Chapter 7 introduces the radio interface protocols, consisting of the data link layer (Layer 2) and the network layer (Layer 3). Chapter 8 presents the guidelines for radio network dimensioning, gives an example of detailed capacity and coverage planning, and covers GSM co-planning. Chapter 9 covers the radio resource management algorithms that guarantee the efficient utilisation of the air interface resources and the quality of service. These algorithms are power control, handovers, admission and load control. Chapter 10 depicts packet access and presents the performance of packet
protocols of WCDMA. Chapter 11 presents the significant Release 5 feature, High-Speed Downlink Packet Access, HSDPA, and its performance. Chapter 12 analyses the coverage and capacity of the WCDMA air interface with bit rates up to 2 Mbps. Chapter 13 introduces the time division duplex (TDD) mode of the WCDMA air interface and its differences from the frequency division duplex (FDD) mode. In addition to WCDMA, third generation services can also be provided with EDGE or with multicarrier CDMA. EDGE is the evolution of GSM for high data rates within the GSM carrier spacing. Multicarrier CDMA is the evolution of IS-95 for high data rates using three IS-95 carriers, and is introduced in Chapter 14.
The second edition contained coverage of the recently introduced key features of 3GPP Release 5 specifications, such as High-Speed Downlink Packet Access, HSDPA and IP Multimedia Sub-system (IMS).
The third edition of the book continues to deepen the coverage of several existing topics, both based on field experiences and more detailed simulation studies. The third edition covers the main updates in 3GPP standard Release 6. Chapter 2 introduces example packetbased person-to-person services, including Push-to-talk over Cellular (PoC), Real time videosharing and multiplayer games. In Chapter 4, standardisation related milestones have Figure 1. Contents of this book been updated and the 3GPP way of working has been described to improve understanding of how things get done in standardisation. In Chapter 6, the beamforming measurements have been added, as well as a discussion of the terminal capabilities available commercially for WCDMA as of today. The new Layer 2/3 related 3GPP items finalised or about to be finalised, early UE handling and Multimedia Broadcast Multicast Service (MBMS), have been added to Chapter 7, along with additional signalling examples. Chapter 9 covers handover measurements from the field. Chapter 10 has been completely rewritten to reflect the latest understanding of the application end-to-end performance over WCDMA, including measurement results from the commercial networks. HSDPA performance has been studied
in more depth in Chapter 11. The next step in the WCDMA evolution, High Speed Uplink Packet Access (HSUPA), is covered in Chapter 11. For the TDD description in Chapter 13, the 1.28 Mcps TDD (known also as Chinese TD-SCDMA) has been covered in more detail.
In general also the feedback received from readers has been taken into account to sharpen the details where necessary, which the authors are happy to acknowledge. In Chapter 14, minor additions have been made to reflect the development on the 3GPP2 side.
This book is aimed at operators, network and terminal manufacturers, service providers, university students and frequency regulators. A deep understanding of the WCDMA air interface, its capabilities and its optimal usage is the key to success in the UMTS business.
