In this paper, the authors propose a novel bandwidth allocation scheme that will guarantee Quality-of-Service (QoS) support in the Down-Link (DL) of a LTE-A system. The proposed scheme is developed based on a queuing model that links important performance metrics of DL service flows of LTE-A systems to a set of tunable parameters. Based on the outcome of the results of the queuing model, the performance metrics are set. The bandwidth allocation scheme then uses the pre-determined performance parameters in making the scheduling decisions.
