Abstract

In this paper the algorithm of a methodology for the calculation of spectrum requirements was implemented. As well, the influence of traffic distribution ratio among radio access technology groups, spectral efficiency, and flexible spectrum usage(FSU) margin was analyzed in terms of the spectrum requirements, with a view toward for future development of IMT-2000 and systems beyond IMT-2000. The ratio of the spectrum requirement to the traffic distribution ratio is approximately $1\;GHz/20\;\%$, and the spectrum requirement varies from 5 to 9 GHz. As the FSU margin increases by 1.0 dB, the total spectrum requirement decreases by 0.9 dB. The required spectrum for the market input parameter, ${\rho}=0.5$ is 801.63 MHz, while the required spectrum for ${\rho}=1.0$ is 6295.4 MHz. It can be concluded that the market input parameter is the most effective parameter in the calculation of spectrum requirements.

본 논문에서는 4세대 이동통신 주파수 소요량 산출 방법론을 구현하고, 주파수 소요량의 변화에 큰 영향을 미치는 RATG간 트래픽 배분을, 주파수 효율성, FSU 이득과 시장 데이터 입력 파라미터 ${\rho}$에 따른 주파수 소요량의 변화를 시뮬레이션 하였다. 트래픽 배분율에 따른 주파수 소요량 변화는 $1\;GHz/20\;\%$정도였으며, 주파수 효율성에 따른 변화는 $5{\sim}9\;GHz$였다. 그리고 FSU 이득이 1 dB 증가하면 주파수 소요량은 약 0.9 dB 정도 감소하였다. 시장 데이터 입력 파라미터 ${\rho}=0.5$ 일 때 주파수 소요량은 801.63 MHz, ${\rho}=1.0$ 일 때는 6295.4 MHz로, 시장 데이터 입력 파라미터가 주파수 소요량에 미치는 영향이 가장 크다.
