Performance evaluation of LTE-unlicensed in handover scenarios

Recently, there is an increasing interest for operating long term evolution (LTE) in unlicensed bands (i.e., LTE-U). Up to date, only a few studies have been reported to show the performance of LTE-U. In this work, we first modify the LENA LTE module in the ns-3 simulator and present extensive simulation results in terms of TCP goodput under LTE-U handover scenarios. Simulation results reveal that a new TCP mechanism is needed for coexistence between LTE-U and LTE.
