Abstract:
In this paper, a comparative study has been carried out between the two most popular
Downlink Resource Scheduling techniques in LTE based on user end mobility. Round
Robin and Proportional Fair techniques have been considered for the analysis. The
study has been performed via simulation using Vienna LTE-A Downlink System Level
Simulator v2.0 Q3 2018 in a Heterogeneous Network scenario. The performances of
the schedulers are evaluated for both stationary and moving users according to average
UE (User End) throughput and average UE spectral efficiency. It is found that Round
Robin technique performs better in lower velocities and Proportional Fair technique
performs better in higher velocities. Keeping the feature in mind, a switching system
combining both the techniques has been proposed.
