본 논문에서는 mmWAVE 대역 기반의 5G New Radio(NR) 시스템 환경에서의 인접주파수대역에 구축된 시스템간의 전파간섭을 분석하고 시스템 간 공존조건을 연구한다. 먼저, 3rd Generation Partnership Project(3GPP)의인접주파수대역 전파간섭 분석 방법론에 기반하여, mmWAVE 대역기반 시스템에서의 인접 시스템 간 간섭 시나리오와 적용 기술들을 설명한다. 특히, mmWAVE 대역의 간섭분석에 처음으로 도입되는 개념인 송수신beam-forming의 효과와 mmWAVE의 전파전파 특성을 고려한 다양한 형태의 신규 network layout의 효과를 설명한다. 컴퓨터 시뮬레이션을 통해 시스템 간 공존시나리오에 따른 성능분석을 수행하였고, 5%-throughput loss를 만족하는 최소 이격을 adjacent-channel-interference-ratio(ACIR) 측면으로 도출하였다. 본 분석을 통해 mmWAVE 대역에서 인접주파수대역에 구축된 5G NR 시스템은 다양한 구축시나리오에서 공존이 가능함을 확인하였다.
