QoS-aware downlink scheduling in multi-carrier communication systems

Abstract

In order to increase the system capacity in next generation wireless networks, defining new packet scheduling and resource allocation algorithms can be an approach. In the context of the existence of multiple Component Carriers in LTE-Advanced, there is an added degree of freedom which can be used for these radio resource management algorithms. This paper presents a QoS-aware scheduling algorithm, designed for use in an LTE-Advanced system. It is compared to traditional algorithms such as Round Robin and Proportional Fair. Results show that in some situations it provides better performances than the previous algorithms.
