The key feature of future mobile communication systems is the
ability to deliver wideband and high bit-rate multimedia services
alongside the traditional radio services such as voice, messaging
and slow rate data. The broad range of services expected to be
supported can be divided into different Quality of Service (Qo S)
classes. However, the provision of such mobile multimedia services
under Qo S guarantees will not be possible without a utilization of
the air interface resources by means of Radio Resource Management
(RRM) strategies that ensure the target Qo S, the planned coverage
area 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 the
description of specific RRM algorithms. The RRM problem for UMTS is
presented, and more specifically, for the FDD mode, which is based
on a WCDMA scheme. More specifically, the different aspects that
are covered include:
* Introduces the mobile communications sector and UMTS, including
the evolution towards 4G systems, with an overview of the Qo S
concept 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 development
of RRM strategies in WCDMA networks
* Analyses particular RRM algorithms in a variety of scenarios,
trying to identify the key parameters and factors that influence
their performance
* Explores the evolution of UMTS towards Beyond 3G systems and
the concept of Common RRM in heterogeneous networks with the aid of
some algorithm examples
This comprehensive title is essential reading for engineers and
managers in radio engineering departments of UMTS network operators
and UMTS equipment manufacturers. It will also prove insightful to
researchers in the field of 3G and Beyond 3G systems and academics
in any of these areas.
