Abstract
Internet of Things (IoT) is considered as a major emerging technology with huge potential in social efficiency and civilian market. However the scarce available spectrum poses obstacles for the increasing amount of IoT devices. The coming 5G new radio (NR) of next generation is expected to exploit the spectrum of super high frequency by utilizing a heterogeneous network comprising the currently Long Term Evolution (LTE) systems and the 5G NR via dual connectivity (DC). This paper gives an overview of the new DC features introduced in Release 15 and an outline of the features and operation procedures in comparison with DC in LTE systems. We also tune the key parameters for different scenarios and it is demonstrated in system level simulations that the performance of DC for 5G NR deployment is significantly improved as compared to the DC in LTE.
