Neste artigo, a capacidade erlang do link direto e a probabilidade de interrupção para o sistema celular hierárquico baseado em macrocélula/microcélula de 2 camadas são derivadas analiticamente considerando o impacto do controle de energia imperfeito e da transferência suave. A análise da probabilidade de interrupção é realizada utilizando dois métodos: aproximação lognormal e limite superior de Chernoff. Assumimos que os usuários dos serviços de voz e dados multitaxa estão distribuídos uniformemente em cada célula e o mesmo espectro é aplicado em ambas as camadas. Além disso, levamos em consideração a relação de potência de transmissão da estação base entre as camadas e a posição relativa da microcélula com distribuição em ilha na macrocélula. A interferência no link direto é avaliada usando a simulação de Monte-Carlo introduzida em [2]. Neste artigo, comparamos a capacidade erlang do link direto do sistema 1x com o sistema 3x e mostramos que o sistema 3x pode aumentar a capacidade do usuário em 3.4 vezes no caso de macrocélula e microcélula, respectivamente, em comparação com o sistema 1x.

Abstract: In this paper, the forward link erlang capacity and outage probability for hierarchical cellular system based on 2 layer macrocell/microcell are derived analytically by considering the impact of imperfect power control and soft hand-off. The analysis on the outage probability is carried out using two methods: lognormal approximation and Chernoff upper bound. We assume that voice and multi-rate data service users are distributed uniformly in each cell and the same spectrum is applied in both layers. In addition, we take into account the base station transmission power ratio between tiers and the relative position of microcell having island distribution in macrocell. The forward link interference is evaluated by using Monte-Carlo simulation introduced in [2]. In this paper, we compare the forward link erlang capacity of 1x system to 3x system and show that 3x system can increase the user capacity by 3.4 times in case of macrocell and microcell, respectively, compared to 1x system.
