Abstract Radio Resource Management Framework for System Level Simulations in LTE-A Systems Panagiotis Fotiadis Aalborg University1, Denmark Department of Electronic Systems E-mail: [email protected] Ingo Viering Nomor Research GmbH Munich, Germany Email: [email protected] Klaus I.

For that pur- pose, an abstract Radio Resource Management (RRM) frame- work 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. Index Terms—LTE-A; Radio Resource Management (RRM); Carrier Aggregation; Modeling; Packet Scheduling I. INTRODUCTION To meet the growing demand for higher data rates, Carrier Aggregation (CA) is introduced in Release 10 Long Term Evolution-Advanced (LTE-A) specifications. In CA mode, two or more Component Carriers (CC) are aggregated to support effectively wider transmission bandwidths [1], reaching up to 100 MHz. Fig. 1 illustrates the basic LTE-A architecture, where the set of parallel streams represents the number of available CCs deployed at the base station. Being designed to be backwards compatible with Release 8 User Equipments (UE), which do not have CA capabilities, each CC follows the principles of the LTE Radio Resource Management (RRM) framework.
