Online resources: Summary: This practical hands-on new resource presents LTE technologies from end-to-end, including network planning and the optimization tradeoff process. This book examines the features of LTE-Advanced and LTE-Advanced Pro and how they integrate into existing LTE networks. Professionals find in-depth coverage of how the air interface is structured at the physical layer and how the related link level protocols are designed and work. This resource highlights potential 5G solutions as considered in releases 14 and beyond, the migration paths, and the challenges involved with the latest updates and standardization process.n nMoreover, the book covers performance analysis and results, as well as SON specifications and realization. Readers learn about OFDMA, and how DFT is used to implement it. Link budgeting, parameter estimations, and network planning and sizing is explained. Insight into core network architecture is provided, including the protocols and signaling used for both data and voice services. The book also presents a detailed chapter on the end-to-end data transfer optimization mechanisms based on the TCP protocol. This book provides the tools needed for network planning and optimization while addressing the challenges of LTE and LTE-advanced networksSummary: 3.3.4 Basic Unit of Time in LTE3.4 Timing Advance Function; 3.5 MBMS Transmission; 3.6 The DL OFDMA and Implementation; 3.6.1 Modulation within eNodeB; 3.6.2 Demodulation Within UE; 3.6.3 Susceptibility to Frequency Offsets; 3.7 The Uplink SC-FDMA and Implementation; 3.7.1 The Implementation Within the UE and eNodeB; 3.8 Channels in LTE; 3.8.1 The Physical Channels; 3.8.2 The Transport Channels; 3.8.3 The Logical Channels; 3.9 Layer 2 Protocol Sublayers; 3.9.1 The MAC Sublayer; 3.9.2 The RLC Sublayer; 3.9.3 The PDCP Sublayer; 3.10 Modulation and Coding Schemes and Mapping TablesSummary: 3.10.1 MCS Index Mapping to Transport Block Size3.10.2 Effective Channel Coding Estimation; 3.10.3 CQI Mapping to MCS; 3.11 Data Rates and Spectral Efficiencies; 3.12 Transmission Modes and MIMO Operation in LTE; 3.12.1 The MIMO Operation; 3.13 LTE Physical Layer Measurements; 3.13.1 In the UE; 3.13.2 In the eNodeB; 3.14 UE Categories; References; 4 Coverage-Capacity Planning and Analysis; 4.1 Radio Link Budgeting for Coverage Dimensioning; 4.1.1 Link Budgeting Formulations; 4.2 Capacity Quality Analysis and Verification; 4.2.1 Capacity EstimationSummary: 4.2.2 Traffic Demand Estimation and Site Calculation4.3 Optimum System Bandwidth for Coverage; 4.4 Trade-Offs Between Network Load and Coverage Performance; References; 5 Prelaunch Parameter Planning and Resource Allocation; 5.1 PCI Allocation; 5.2 Uplink Reference Signal Allocation; 5.2.1 Using Cyclic Shifts of the ZC Sequences; 5.2.2 Defining u Independently from PCI; 5.2.3 Pseudo-Random u-Hopping; 5.3 Random Access Planning; 5.3.1 PRACH Preamble Format Selection and Parameter Setting; 5.3.2 Derivation and Assignment of Preamble Sequences; 5.3.3 RootSequenceIndex PlanningSummary: 5.3.4 PRACH Capacity Planning5.4 PRACH Procedure; 5.5 PRACH Optimization; References; 6 Radio Resource Control and Mobility Management; 6.1 RRC State Model in LTE; 6.1.1 RRC Idle State; 6.2 Handovers in LTE; 6.2.1 Intrasystem Handover; 6.2.2 Inter-RAT Handover; 6.2.3 Handover Performance and Optimization; 6.2.4 Impact of Measurement Filtering; 6.2.5 Impact of Measurement Hysteresis and Time-to-Trigger Parameters; 6.2.6 Impact of RLC/MAC Protocol Resets and Packet Forwarding; 6.2.7 E-UTRAN to E-UTRAN Handover Delay (FDD); 6.2.8 E-UTRAN to UTRAN Handover DelaySummary: From LTE to LTE-Advanced Pro and 5G; Contents; Preface; 1 Introduction; References; 2 The Underlying DFT Concepts and Formulations; 2.1 Discrete-Time Fourier Transform; 2.2 The Discrete Fourier Transform; 2.3 Zero-Padding for Efficient FFT Implementation; 2.4 Frequency Resolutions and Impact of Zero Padding; References; 3 The Air Interface Architecture and Operation; 3.1 Spectrum Allocation; 3.2 The OFDM Multi-User Access Mechanism; 3.3 The Framing and Physical Synchronization Signals; 3.3.1 The Type 1 FDD Frame Structure; 3.3.2 The Type 2 TDD Frame Structure; 3.3.3 Physical Reference SignalsPPN: PPN: 1047996081Package identifier: Produktsigel: ZDB-4-EBA | ZDB-4-ENC | ZDB-4-NLEBK
