Performance comparison of network layouts with mobile users under different resource scheduling techniques in downlink LTE

摘要

LTE-A addresses the challenges of coverage block holes and increase in user density with new features, such as small cell and femto cell. Small cell can be an inexpensive substitute to macro cell in coverage depleted areas. In contrast, heterogeneous network using femto cells with its ubiquitous coverage, can deliver high-speed data. Resource scheduling algorithm has an important role in determining the overall system performance. Several schedulers are available whose performance ranges from maximizing UE throughput to achieving the best fairness. UE mobility significantly affects the performance of different network topologies and various scheduling algorithms. In this paper, we have evaluated and compared various LTE downlink performance parameters between small cell network and heterogeneous network to conclude which type of network deployment is best suited for mobile users and dense urban environment under different scheduling schemes.
