  Abstract

This paper studies adjacent channel interference (ACI) between wireless systems that are allocated in adjacent frequency bands and investigates their coexistence in mmWAVE-based 5G New Radio(NR) systems. By using ACI analysis methodology proposed for the 3rd Generation Partnership Project (3GPP), we describe the inter-system interference scenarios and apply advanced techniques for mmWAVE-based systems. In particular, we focus on the impact of transmit/receive beam-forming, which is one of the major extension of the ACI analysis methodology targeting mmWAVE band. Various types of new network layouts, including indoor layout and uncoordinated hot-spot layout, have been investigated considering the propagation models of mmWAVE. We perform computer simulation to verify the coexistence performance of mmWAVE-based 5G systemsfrom 5%-tile throughput loss of the ACIR aspect, where we derive the minimum required ACIR for solid coexistence. Based on the analysis and simulation results, we verify that mmWAVE-based 5G NR systems satisfy coexistence requirements in various practical deployment scenarios.
