Modeling of common radio resource management scenarios

In this paper we first present a systematic view on common radio resource management (CRRM) problems. Then we classify different CRRM levels and propose a categorization framework for CRRM algorithms based on their relationship to load sharing strategies. The proposed model framework based on this systematic view enables a cost-benefit analysis of different CRRM algorithms and architectures. Different centralized or decentralized scenarios can be clearly defined based on five standard components (the radio access system, the environment, the user equipment, the CRRM information manager and the CRRM decider). The costs of CRRM operations are taken into account via chargeable messages. The clarity of the model enables an efficient investigation of CRRM algorithms based on optimization theory, game theory, physical models and other methods. We also describe the implementation concept of the model framework.
