Evaluation of a Cross Layer Scheduling Algorithm for LTE Downlink

The LTE standard is a leading standard in the wireless broadband market. The Radio Resource Management at the base station plays a major role in satisfying users demand for high data rates and quality of service. This paper evaluates a cross layer scheduling algorithm that aims at minimizing the resource utilization. The algorithm makes decisions based on the channel conditions, the size of the transmission buffers and different quality of service demands. The simulation results show that the new algorithm improves the resource utilization and provides better guaranties for service quality.
