Abstract

MÉTODOS E APARELHO PARA SERVIÇO DE DIFUSÃO E MULTIDIFUSÃO SEM FIO Versões incluem métodos e aparelho associado aos serviços multidifusão e/ou de difusão sem fio. Uma estação base (102, Figura 1) transmite códigos de dados (504, 604, 702, Figuras 5 a 7) dentro de um quadro de rádio (300, Figura 3). Os códigos de dados são códigos de dados de Acesso Múltiplo por Divisão de Código (CDMA), em uma 10 versão. A estação base também transmite um código de sincronização Multiplexado por Divisão de Tempo (TDM) (502, 608, 706, Figuras 5 a 7), em uma versão. A estação base transmite descontinuamente (1004, Figura 10) uma parte de um sulco de quadro de rádio que é coincidente no tempo com a duração do código de sincronização TDM, em várias versões. A parte transmitida descontinuamente do sulco de quadro de rádio poderá incluir bits Indicadores de Combinação de Formato de Transporte (TFCI) (510 , Figura 5), bits pilotos (710, Figura 7), ou bits de dados (612, Figura 6), em várias versões. As transmissões de uma estação base poderão ser síncronas no tempo e freqüência com a transmissão de outras estações base.
