內容簡介

　　 《4G：LTE/LTE-Advanced 寬帶移動通信技術（影印版）》基於獲得巨大成功的書籍《3G演進-HSPA與LTE》，新版集中關注LTE和LTE-Advanced（Rl0），對LTE的關鍵技術和LTE標準做瞭全麵的介紹，並對各種LTE技術詳細解釋其方法和采納理由。本書清晰地闡明瞭各種LTE關鍵技術，並深入地解釋瞭各種特定的LTE解決方案，因此，有助於讀者理解在移動寬帶産品和係統中如何實現和部署LTE。
　　 包含瞭新增加到LTE無綫接入標準和技術（包括3GPPR10）中的全部細節；
　　 清晰地解釋瞭支撐LTE的關鍵技術（包括OFDM和MIMO）的作用；
　　 完整地涵蓋瞭提交到國際電聯無綫通信組的LTE-Advanced關鍵技術（包括LTE載波聚閤、擴展多天綫傳輸、中繼、異構網）；
　　 詳細地闡釋瞭LTE無綫接口結構、物理層、接入過程、廣播、射頻特性和係統性能。
　　 Erik Dahlman、Stefan Parkvall和Johan Skold都是愛立信研究院資深研究員，自3G研究的初始階段就一直深入開展3G與4G技術的研發和標準化工作。他們是3G/4G領域的一流專傢，目前仍積極為3GPPLTE的標準化工作做著突齣的貢獻。

精彩書摘

The work on LTE was initiated in late 2004 with the overall aim of providing a new radio-accesstechnology focusing on packet-switched data only. The first phase of the 3GPP work on LTE was todefine a set of performance and capability targets for LTE [10]. This included targets on peak datarates， user/system throughput， spectral efficiency， and control/user-plane latency. In addition， require-ments were also set on spectrum fiexibility， as well as on interaction/compatibility with other 3GPPradio-access technologies （GSM， WCDMAfHSPA， and TD-SCDMA）.
Once the targets were set， 3GPP studies on the feasibility of different technical solutions consid-ered for LTE were followed by development of the detailed specifications. The first release of theLTE specifications， release 8， was completed in the spring of 2008 and commercial network operationbegan in late 2009. Release 8 has then been followed by additional LTE releases， introducing addi-tional functionality and capabilities in different areas， as illustrated in Figure.
7.1.In parallel to the development of LTE， there has also been an evolution of the overall 3GPPnetwork architecture， termed System Architecture Evolution （SAE）， including both the radio-accessnetwork and the core network. Requirements were also set on the architecture evolution， leading toa new flat radio-access-network architecture with a single type of node， the eNodeBl， as well as a newcore-network architecture. An excellent descnption of the LTE-associated core-network architecture，the Evolved Packet Core （EPC）， can be found in [9].
The remaining part of this chapter provides an overview of LTE up to and including release 10.The most important technologies used by LTE release 8 - including transmission schemes， schedul-ing， multi-antenna support， and spectrum flexibility - are covered， as well as the additional featuresintroduced in LTE releases 9 and 10. The chapter can either be read on its own to get a high-leveloverview of LTE， or as an introduction to the subsequent chapters.
The following chapters， Chapters 8-18， then contain a detailed description of the LTE radio-accesstechnology. Chapter 8 provides an overview of the LTE protocol structure， including RLC， MAC， andthe physical layer， explaining the logical and physical channels， and the related data flow. The time-frequency structure on which LTE is based is covered in Chapter 9， followed by a detailed descriptionof the physical layer for downlink and uplink transmission in Chapters 10 and 11 respectively. Chapter12 contains a description of the retransmission mechanisms used in LTE， followed by a discussion onpower control， scheduling， and interference management in Chapter 13. Access procedures， necessaryfor a terminal to connect to the network， are the topic of Chapter 14. Chapter 15 covers the multi-cast/broadcast functionality of LTE and Chapter 16 describes relaying operation. Chapter 17 addresseshow radio-frequency （RF） requirements are defined in LTE， taking into account the spectrum flexibility.Finally， Chapter 18 contains an assessment of the system performance of LTE.
