초록

본 논문은 NS-3 기반의 5G 시스템 레벨 시뮬레이터를 활용하여 mmWave 대역의 채널 모델을 구현하고, RF 성능 검증을 통해 구현한 모델의 신뢰성과 유효성을 분석한다. mmWave 대역의 RF 성능 검증을 위한 채널 모델은 3GPP TR 38.901에서 정의하는 채널의 특성, 빔포밍, 안테나 구성, 시나리오 등의 파라미터를 고려하여 구성한다. 또한, 시뮬레이션 결과는 3GPP 표준에서 허용하는 범위 내에 있음을 확인하고, REM(Radio Environment Map)을 활용하여 실내 환경 시나리오에서 신뢰성을 증명한다. 따라서 본 연구에서 구현한 채널 모델은 실제 5G 네트워크의 설계 및 구축에 적용이 가능하며, 다양한 파라미터 변경으로 RF 성능을 평가하고 검증하는 방법을 제시한다.

This paper implements a channel model for mmWave bands using an NS-3-based 5G system-level simulator and analyzes the reliability and validity of the implemented model through RF performance verification. The channel model for RF performance verification in the mmWave bands consider parameters such as characteristics defined in 3GPP TR 38.901, beam-forming, antenna configuration, scenarios, among others. Furthermore, the simulation results verify compliance within the ranges permitted by the 3GPP standards and verify reliability in indoor environmental scenarios by exploiting the Radio Environment Map (REM). Therefore, the channel model implemented in this study is applicable to the actual design and establishment of 5G networks, presenting a method to evaluate and validate RF performance by adjusting various parameters.
