To exploit such diversity while guaranteeing the interoperability and efficient management of the different RATs, common radio resource management (CRRM) techniques need to be defined. This work proposes and evaluates a CRRM policy that simultaneously assigns to each user an adequate combination of RAT and number of radio resources within such RAT to guarantee its QoS requirements.

INTRODUCTION  \nThere is a wide consensus in the research community that Beyond 3G wireless systems will consist of heterogeneous mobile and wireless Radio Access Technologies (RATs) physically coexisting, but with distinct performance and technical characteristics. Ensuring their interoperability would allow an efficient use of their common radio resources to guarantee the user required Quality of Service (QoS) levels and the maximum systems’ revenue. To achieve these objectives, a key feature of heterogeneous Beyond 3G wireless systems will be the definition of adequate Common Radio Resource Management (CRRM) policies. CRRM techniques are aimed at deciding the RAT over which to convey a user transmission (RAT selection), and the number of resources from the selected RAT (intra-RAT RRM) that the transmission would require to satisfy the QoS requirements. Several studies separately tackle the RAT selection and the intra-RAT RRM dilemmas. For example, [1] and [2] propose intra-RAT RRM policies based on utility functions and economic laws. While the authors in [1] suggest applying auctions principles to maximize the operator’s benefit, [2] proposes the use of bankruptcy-based resource allocation policies to guarantee user fairness and avoid channel access stagnation under heterogeneous traffic environments. In terms of RAT selection techniques, [3] proposes a general framework for their definition, and some specific examples based on pre-established service/RAT assignments. Additional RAT selection principles based on signal strength and instantaneous loads are proposed and evaluated in [4].  \nInitial proposals to jointly address the RAT selection and intra-RAT RRM dilemmas have been recently proposed. For example, [5] proposes a CRRM algorithm based on neural networks and fuzzy logic that simultaneously determines the most appropriate RAT and bit rate allocation, considering, among other factors, the user QoS constraints. While [5] determines the necessary bit rate at the assigned RAT, it does not tackle the problem of intra-RAT radio resources assignment. In this context, this work proposes and evaluates a CRRM policy that simultaneously assigns to each user an adequate combination of RAT and number of radio resources within such RAT to guarantee the user/service QoS requirements. The proposed algorithm is based on linear programming optimization techniques, which have shown significant benefits in other areas, and have been recently applied for the first time to CRRM in [6] to address the RATselection dilemma. The work reported in [6] proposes a joint call admission c","cbCaiu411yDTM20w","https://ap.wps.com/l/cbCaiu411yDTM20w","pdf",1604277,3,1,5,"English","en",105,"# Abstract\n# Introduction\n# Utility
