Abstract Radio Resource Management Framework for System Level Simulations in LTE-A Systems

Abstract

Abstract-This paper provides a simple mathematical model of different packet scheduling policies in Long Term EvolutionAdvanced (LTE-A) systems, by investigating the performance of Proportional Fair (PF) and the generalized cross-Component Carrier scheduler from a theoretical perspective. For that purpose, an abstract Radio Resource Management (RRM) framework has been developed and tested for different ratios of users with Carrier Aggregation (CA) capabilities. The conducted system level simulations confirm that the proposed model can satisfactorily capture the main properties of the aforementioned scheduling metrics without any need for explicit design at a subframe resolution; hence, making it a promising candidate for a convenient scheduler implementation in simulators with simplified RRM modelling.
