  Abstract

Recently, as 5G NR(New Radio) wireless communication has been commercialized in earnest, users are demanding faster wireless access and higher data throughput. In order to support higher data throughput from the base station side, a dual connectivity function is essential. The dual connectivity function inevitably requires reordering of packets at the receiving end. In addition, due to the nature of the reordering timer, a packet that is not received until the reordering time expires is determined as a loss, and this loss appears as a decrease in data throughput. In this paper, we propose a reordering time optimization method to stably support higher data throughput without instantaneous reduction, and show the performance of the proposed technology through simulation results.
