미래의 셀룰러 이동 통신을 위해 계층적 매크로셀/마이크로셀 아키텍처가 제안되었습니다. 계층적 셀룰러 시스템에 대한 성능 분석은 중요한 문제가 됩니다. 본 논문에서는 불완전한 전력 제어가 로그 정규 통계를 따른다고 가정하고 [1][2][8]의 분석 방법을 확장하고 매크로셀과 마이크로셀에 대해 서로 다른 감쇠 모델을 사용하여 시스템의 용량 평면과 정전 확률을 분석합니다. 완벽한 부문화 유무에 관계없이 조사되고 정량화됩니다. IS-95 프로토콜의 매개변수 수치 결과를 보면 상대적으로 엄격한 전력 제어와 섹터 간 중첩이 좁은 경우 높은 사용자 용량과 낮은 중단 확률을 기대할 수 있습니다. 이러한 결과는 이전에 발표된 CDMA 비계층적 셀룰러 시스템 추정과 비교됩니다. 계층적 셀룰러 시스템을 적용하면 비계층적 셀룰러 시스템보다 동일한 대역폭 2.3MHz로 사용자 용량을 1.25배 늘릴 수 있다.

Abstract: Hierarchical macrocell/microcell architectures have been proposed for future cellular mobile communication. The performance analysis for the hierarchical cellular system becomes an important issue. In this paper, extending the analytical methods from[1][2][8], assuming that the imperfect power control follows log-normal statistics, and employing different attenuation models for macrocells and microcells, the capacity plane and outage probability of the system are examined and quantified with and without perfect sectorization. From the numerical results of parameters of IS-95 protocol, the high user capacity and lower outage probability may be expected in the case of relatively tight power control and narrower overlap between sectors. These results are compared with the previously published CDMA nonhierarchical cellular system estimation. When we employ the hierarchical cellular system, we can increase the user capacity 2.3 times with the same bandwidth 1.25 MHz than the one of the nonhierarchical cellular system.

The performance analysis for the hierarchical cellular system becomes an important issue.
