Analysis of Dual Connectivity Gain in Terms of Delay and Throughput

Abstract

Dual connectivity is very important for gradual transition from LTE to 5G. Release 12 of the 3GPP specification introduced DC scheme, but what advantage we can get from DC is not evaluated yet. In this paper, we simulate the DC schemes (LTE LTE DC, LTE-mmWave DC, mmWave - mmWave DC) using newly modified network simulator (NS3) for 5G and evaluate the DC gains in terms of throughput and delay. We demonstrate the DC would increase the throughput under the fast switching scheme and decrease the end-to-end delay a lot.
