The key feature of future mobile communication systems is theability to deliver wideband and high bit-rate multimedia servicesalongside the traditional radio services such as voice, messagingand slow rate data. The broad range of services expected to besupported can be divided into different Quality of Service (QoS)classes. However, the provision of such mobile multimedia servicesunder QoS guarantees will not be possible without a utilization ofthe air interface resources by means of Radio Resource Management(RRM) strategies that ensure the target QoS, the planned coveragearea and that offer a high system capacity.Under this framework, the book focuses on the RRM concepts,including the theoretical background that serves as a basis for thedescription of specific RRM algorithms. The RRM problem for UMTS ispresented, and more specifically, for the FDD mode, which is basedon a WCDMA scheme. More specifically, the different aspects thatare covered include:* Introduces the mobile communications sector and UMTS, includingthe evolution towards 4G systems, with an overview of the QoSconcept which is key for the definition of RRM strategies* Offers a detailed description of the radio interface in UMTS,as the basis for the implementation of RRM strategies* Provides the fundamental concepts related with the developmentof RRM strategies in WCDMA networks* Analyses particular RRM algorithms in a variety of scenarios,trying to identify the key parameters and factors that influencetheir performance* Explores the evolution of UMTS towards Beyond 3G systems andthe concept of Common RRM in heterogeneous networks with the aid ofsome algorithm examplesThis comprehensive title is essential reading for engineers andmanagers in radio engineering departments of UMTS network operatorsand UMTS equipment manufacturers. It will also prove insightful toresearchers in the field of 3G and Beyond 3G systems and academicsin any of these areas.
