Abstract

"CONTROLE DE INTERFERêNCIA EM UMA CéLULA DE UM SISTEMA DE TELECOMUNICAçõES SEM FIO". A presente invenção fornece um controlador de interferência e um método de limitação em uma célula do efeito de interferência gerado por outras células de um sistema de telecomunicações sem fio, cada célula do sistema de telecomunicações sem fio possuindo um terminal central e uma conexão sem fio, e uma pluralidade de canais multiplexados de divisão de código sendo fornecidos dentro de um canal de freq³ência única para permitir que os itens de dados pertencentes a uma pluralidade de conexões sem fio sejam transmitidos simultaneamente dentro de diferentes canais multiplexados de divisão de código do dito canal de freq³ência único. O controlador de interferência compreende um analisador para comparar com os parâmetros de críterios predeterminados dentro da célula que indica se os canais multiplexados de divisão de código são sujeitos à interferência dos sinais gerados pelas ditas outras células; e um controlador de canal, que responde ao analisador, para evitar seletivamente que os canais multiplexados de divisão de código sejam utilizados a fim de reduzir o efeito da interferência das ditas outras células, Nas modalidades preferidas, o controlador de interferência é fornecido dentro de um terminal central de pelo menos uma célula do sistema de telecomunicações sem fio.
