The difference in design, implementation, and use between telecom and datacom technologies is also becoming more blurred. One example is cellular technologies from the telecom world being used for broadband data and wireless Lan from the datacom world being used for voice-over IP. Today, the most widespread radio access technology for mobile communication is digital cellular, with the number of users passing 5 billion by 2010, which is more than half of the world,'s popula tion. It has emerged from early deployments of an expensive voice service for a few car-borne users to today's widespread use of mobile-communication devices that provide a range of mobile services and often include camera, MP3 player, and PDa functions. With this widespread use and increasing interest in mobile communication, a continuing evolution ahead is foreseen This book describes LtE, developed in 3GPP (Third Generation Partnership Project)and provid ing true 4G broadband mobile access, starting from the first version in release 8 and through the con- tinuing evolution to release 10, the latest version of lte. release 10. also known as LtE-advanced is of particular interest as it is the major technology approved by the itu as fulfilling the IMt- Advanced requirements. The description in this book is based on LtE release 10 and thus provides a complete description of the lte-Advanced radio access from the bottom up Chapter 1 gives the background to LtE and its evolution, looking also at the different standards bodies and organizations involved in the process of defining 4G. It also gives a discussion of the rea sons and driving forces behind the evolution Chapters 2-6 provide a deeper insight into some of the technologies that are part of lte and its evolution. Because of its generic nature, these chapters can be used as a background not only for LtE as described in this book, but also for readers who want to understand the technology behind other systems, such as WCDMA/HSPA, WiMAX, and CDMa2000 Chapters 7-17 constitute the main part of the book. as a start, an introductory technical over view of ltE is given, where the most important technology components are introduced based on the generic technologies described in previous chapters. The following chapters provide a detailed description of the protocol structure, the downlink and uplink transmission schemes, and the associ ated mechanisms for scheduling, retransmission and interference handling Broadcast operation and relaying are also described. This is followed by a discussion of the spectrum flexibility and the associ ated requirements from an RF perspective Finally, in Chapters 18-20, an assessment is made on LtE. Through an overview of similar tech nologies developed in other standards bodies, it will be clear that the technologies adopted for the evolution in 3GPP are implemented in many other systems as well. Finally, looking into the future it will be seen that the evolution does not stop with LtE-Advanced but that new features are continu ously added to Lte in order to meet future requirements Acknowledgements We thank all our colleagues at Ericsson for assisting in this project by helping with contributions to the book, giving suggestions and comments on the contents, and taking part in the huge team effort of developing LTE The standardization process involves people from all parts of the world, and we acknowledge the efforts of our colleagues in the wireless industry in general and in 3GPP RAN in particular. Without their work and contributions to the standardization, this book would not have been possible Finally, we are immensely grateful to our families for bearing with us and supporting us during the long process of writing this book XV Abbreviations and Acronyms 3GPP Third Generation Partnership Project 3GPP2 Third Generation Partnership Project 2 ACIR Adjacent Channel Interference ratio ACK Acknowledgement (in ARQ protocols) ACLR Adjacent Channel leakage ratio ACS Adjacent Channel Selectivity AM Acknowledged Mode(rlc configuration) AMC Adaptive Modulation and Odin A-MPR Additional maximum power reduction AMPS Advanced Mobile Phone system AQPSK Adaptive QPsK ARI Acknowledgement Resource Indicator ARIB Association of radio Industries and businesses ARo Automatic Repeat-re Quest AS Access stratum ATIS Alliance for Telecommunications Industry Solutions AWGN Additive white gaussian noise BC Band Category BCCH Broadcast Control channel BCH Broadcast Channel BER Bit-Error rate BLER Block -Error rate BM-SC Broadcast multicast service Center BPSK Binary Phase-Shift Keying BS Base station BSC Base station controller BTS Base transceiver station CA Carrier Aggregation CC Convolutional Code (in the context of coding), or Component Carrier (in the context of carrier aggregation) CCCH Common Control channe CCE Control channel element CCSA China Communications standards association CDD Cyclic-Delay Diversity CDF Cumulative Density Function CDM Code-Division Multiplexing CDMA Code-Division Multiple access XVI xviii Abbreviations and acronyms CEPT European Conference of Postal and Telecommunications Administrations CN Core Network COMP Coordinated Multi-Point transmission/reception CP Cyclic Prefix CPC Continuous packet Connectivit CQI Channel-Quality Indicator C-RAN Centralized ran CRC Cyclic Redundancy Check C-RNTI Cell Radio-Network Temporary Identifier CRS Cell-specific Reference Signal CS Circuit Switched (or Cyclic Shift) CS Capability Set(for Msr base stations) CSA Common Subframe allocation CSG Closed Subscriber group CSI Channel-State Information CSI-RS CSI reference signals CW Continuous wave DAI Downlink Assignment Index DCCH Dedicated Control channel DCH Dedicated channe DCI Downlink control information DFE Decision-Feedback equalization DFT Discrete fourier transform DFTS-OFDM DFT-Spread OFDM DFT-precoded OFDM, See alSo SC-FDMA DL Downlink DL-SCH Downlink shared Channe DM-RS Demodulation Reference Signal DRX Discontinuous reception DTCH Dedicated Traffic Channel DTⅩ Discontinuous transmission DWPTS The downlink part of the special subframe(for TDD operation) EDGE Enhanced Data rates for gSM Evolution Enhanced data rates for global evolution EGPRS Enhanced gPrs eNB eNodeB eNodeB E-UTRAN NOdeB EPC Evolved packet core EPS Evolved Packet System ETSI European Telecommunications Standards Institute E-UTRA Evolved utra E-UTRAN Evolved UTRAN EV-DO Evolution-Data Only(of cdma2000 lx) EV-DV Evolution-Data and Voice (of CDMA2000 1x) EVM Error Vector Magnitude
