Abstract

"APARELHO E MéTODO PARA TRANSMITIR DADOS DE CONTROLE POR UM CANAL NUM SISTEMA DE COMUNICAçãO CDMA". Método para transmitir dados de controle por um canal de sinal de recepção e/ou sinal de transmissão numa estação de base e/ou estação móvel em um sistema de comunicação móvel. Em uma modalidade, a estação de base determina se há dados de canal de sinal de recepção para transmitir para uma estação móvel. Se não houver dados a serem transmitidos pelo canal de sinal de recepção por um período de tempo predeterminado, a estação de base aciona um seletor de posição aleatória de porteamento para determinar uma posição aleatória de abertura de porteamento, abre a porta para os dados de controle em uma posição determinada de abertura e fecha a porta para os dados de controle em outras posições de abertura. O seletor de posição aleatória determina a posição de abertura de porteamento calculando um valor x multiplicando um número de quadro de sistema (SFN ) de um sinal recebido por um número inteiro específico; selecionando n bits começando a partir de uma posição que está a uma distância de x chip a partir do ponto de início de um código embaralhador, que tem um período igual a um quadro, antes de uma série de durações de porteamento usadas na geração de um sinal de recepção; e determinando uma posição de abertura de porteamento de um grupo de abertura de porteamento correspondente realizando uma operação modular dos n bits selecionados, onde a operação modular é pelo número de aberturas em um grupo de aberturas de porteamento.
