Abstract

In this paper, a centralized mmWave-based multi-spot beam cellular system architecture having such a base station equipped with a plurality of beam-forming antennas, multi-layered dynamic cell configuration method as one of key concepts of this system operation and a mobility management method based on it are introduced. To estimate the performance of new system, system simulation was performed under the ideal environment without blockage. These results show the possibility that system capacity can be dramatically increased and mobility performance similar to the existing cellular system may be achieved.

본 논문에서는 기지국에 다수개의 빔포밍 안테나들을 장착한 형태의 중앙 집중형 밀리미터파 기반 다중 스팟빔 셀룰러 시스템 구조와 이 시스템 운용의 핵심 개념인 다계층 동적 셀 구성 방법 그리고 이를 이용한 이동성 관리 방법을 소개하고 있다. 차단이 없는 이상적 환경에서의 시스템 시뮬레이션 결과를 통하여 밀리미터파를 이용한 이러한 시스템 구조 및 운용이 기존 셀룰러 시스템 대비 시스템 용량을 크게 높여줄 수 있고 유사한 이동 성능을 제공할 수 있다는 가능성을 보여 주고 있다.
