Abstract

esquema de transmissão de acesso múltiplo para um sistema sem fio. um sistema de comunicação de acesso múltiplo sem fio (5) compreende um enlace direto (31) para um terminal (40) e um enlace reverso (32) a partir de um terminal (40). o enlace reverso (32) utiliza um meio que é compartilhado entre terminais (40) com base no tempo e na frequência. um terminal (40) transmite um sinal de enlace reverso (32) a partir do terminal compreendendo uma sequência de slots de transmissão (51, 52, 53), cada slot de transmissão sendo definido como um intervalo de tempo, e uma frequência de portadora, sendo que a frequência de portadora e a taxa de símbolos podem mudar entre slots de transmissão. o sinal de enlace reverso (32) é transmitido continuamente ao longo da sequência de slots de transmissão (51, 52, 53). o terminal pode transmitir um sinal de enlace reverso (32) que é contínuo em fase ao longo dos slots de transmissão.
