Abstract

<B>SISTEMA DE COMUNICAçãO RáDIO CELULAR<D> A invenção relaciona-se ao campo de sistemas de comunicação rádio. Em um sistema de comunicação rádio celular: i) pelo menos um sinal que compreende informações de canal de controle é radiodifundido em uma portadora para assinantes dentro do sistema de comunicação rádio celular; ii) a dita portadora é dividida em quadros TDMA, cada quadro TDMA tendo um número de quadro (N); iii) o sistema é adaptado para armazenar pelo menos dois conjuntos (S0-S2) de freq³ências predeterminadas (f1), a dita portadora sendo radiodifundida em qualquer tempo em particular em uma freq³ência tirada de um conjunto selecionado dos ditos conjuntos (S0-S2) de freq³ências predeterminadas (f1); iv) O sistema é adaptado para escolher o dito conjunto selecionado dos ditos conjuntos de freq³ências predeterminadas (f1) em dependência no número de quadro (N) do quadro TDMA que estiver sendo radiodifundido no dito tempo. A invenção também compreende uma estação de assinante, por exemplo, um rádio móvel ou telefone, para utilização em tal sistema, e método de transmitir sinais em um sistema de comunicação rádio celular. A invenção permite que o sistema rádio empregue tanto o salto de freq³ência como a transmissão multislot, por exemplo, em um sistema GSM EDGE Compact. Essas duas técnicas servem respectivamente para reduzir a taxa de erro de transmissão e aumentar a velocidade de dados de transmissão.
