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

This paper aims at the theoretical modeling of different packet schedulers in Long Term Evolution-Advanced (LTE-A) systems. For that purpose, an abstract Radio Resource Management (RRM) framework has been developed, considering Proportional Fair (PF) and cross-Component Carrier scheduling. To validate our work, extensive system level simulations have been conducted for different ratios of users with Carrier Aggregation (CA) capabilities. The associated results confirm that the proposed model satisfactorily captures 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 modeling.
