LTE soft handover based on hysteresis and threshold combination

Abstract

This paper proposes the combination of hysteresis and threshold based soft handover in the long-term evolution (LTE) network and presents the performance evaluation. As the simulation conducted, the observations of the generated data show that the threshold margin of -115 dBm with hysteresis margin 24 produces the highest active set, achieving 2.082. The higher the active set value results the lower the outage probability. Outage probability for threshold value of -115 dBm occurs at distance 611 m, reaching only 2.1x10-7.
