Abstract

Método de redução de interferência intercelular em sistema de comunicações móveis. Método de redução de interferência intercelular (ICI) em sistema de comunicações móveis controla a potência de sinal de transmissão de sinal por link superior a partir de terminal com base na medição da potência de sinal para sinal recebido de estação base de célula vizinha. Terminal recebe sinal de estação base de célula vizinha por meio de canal sem fio, mede resposta de canal contra valor limite ao longo de faixa de freqüências aplicável utilizando o sinal recebido, determina potência de sinal de transmissão para cada faixa de freqüências utilizada para transmissão de dados com base na resposta de canal medida e transmite dados para estação base de célula doméstica conforme a potência de sinal de transmissão para cada faixa de freqüências. O terminal pode medir resposta de canal com base em sinais recebidos de diversas estações base em várias células vizinhas e pode também avaliar a potência de sinal transmitido a partir da célula doméstica.
