The chapter presents the aforementioned characteris- Preface tics for the FDD and TDD separately for each mode or unified when the case applies to both. Chapter 5 introduces the UTRA transmission system starting from the spectrum alloca- tion, i.e. the UTRA frequency bands. It presents the radio transmission and reception aspects, describing transmitter and receiver characteristics for the User Equipment (UE) and the Base Station (BS). It describes the maximum output power and output power dynamics, out of synchronization output power handling, transmit on/off power. Details on the output RF spectrum emissions, such as occupied bandwidth and out band emis- sion, spectrum emissions, adjacent channel leakage power ratio, spurious emissions, and transmit modulation and inter-modulation are given. The summary of examples in- cludes a review of simulation scenarios for the co-existence of FDD/FDD when analyz- ing ACIR with macro-to-macro and macro-to-micro cases. Before presenting results the chapter also reviews propagation models. Chapter 6 describes the UMTS service components. It covers the UMTS bearer archi- tecture, concepts in quality of service for 3G systems, multimedia transmission and traf- fic classes in UMTS. The classes include conversational, streaming, interactive, and background types. Sensitivity to IP transmission impairments are also covered here. To provide an overview of potential applications in UMTS this chapter also summarizes service offerings and selected areas of service technology. Chapter 7 introduces the factors that influence 3G network dimensioning. It discusses coverage and capacity trade-off in the FDD mode pointing out impacts from soft hand- over, power control and orthogonality deviations. It covers the analysis of parameters for multi-service traffic in PS and CS. It establishes service models starting from capac- ity projections, and service strategy. Cellular coverage planning issues, i.e. the coverage concept, radio network parameter assumptions for CS and PS, characteristics
