Split Algorithm with a PDCP Reordering Function for LTE/mmWave Dual Connectivity

Abstract

On the transition toward 5G communication service from LTE communication service, Non-Stand Alone scenario is required. Generally, when two different base stations are available, it seems like better throughput and reliability is expected, but it needs well-coordinated controlling algorithm. In this paper, we consider LTE/mmWave dual connectivity to find a way to make use of two different radio technology, LTE and mmWave. To utilize both links simultaneously, we propose a split algorithm that includes a traffic split operation and a packet reordering operation. And, the proposed split algorithm is evaluated through ns-3 simulation.
