Abstract

Millimetre Wave (mmWaves) communication is a major capacity booster to the fifth generation (5G) mobile network. However, challenges of significant attenuation and high propagation losses lead to intermittent user connectivity. This limit mmWave applicability in the 5G mobile network. The dual connectivity (DC) architecture with its split control and data plane functionality has proven to be more effective. The DC model uses the less attenuated Long Term evolution (LTE) bands to coordinate mmWave cells while they provide on demand high capacity rates. This guarantees prolonged network association for mmWave links with minimal to no signalling cost at high user data rates. Minimizing signalling cost in LTE bands considering their scarcity is vital too. To that effect, intelligent Handoff (HO) strategies that prolong mmWave link association using minimal signalling cost are vital for a robust DC system. This paper investigates the performances of adaptive HO strategies given a highway multiuser-type mobility scenario on DC systems. Results show that adaptive HO solutions enhance link reliability in mmWaves with minimal signalling cost.
