Radio resource management in beyond 3G systems

Beyond 3G systems is usually the term used to refer to the new scenarios in the wireless arena where different radio access technologies (RATs) coexist and operate in a coordinated way. This cooperation must indeed be regarded as a new challenge to offer services to the users over an efficient and ubiquitous radio access. In this way, the user can be served through the RAT that fits better to the terminal capabilities and service requirements, and also a more efficient use of the radio resources can be achieved. This challenge calls for the introduction of new radio resource management (RRM) algorithms operating from a common perspective that take into account the overall amount of resources offered by the available RATs. In this context, this paper presents the framework for developing RRM algorithms in the B3G scenarios, including some possible approaches.
