Abstract

"MéTODO E EQUIPAMENTO PARA TRANSFERêNCIA DE MENSAGENS DE OVERHEAD EM UM SISTEMA DE COMUNICAçãO SEM FIO". Método e equipamento para prover uma mensagem de parâmetros de sistema de broadcast em um sistema de comunicação sem fio que suporta um serviço de broadcast. Em uma modalidade, a mensagem identifica um número de opção de serviço correspondente a conjunto de parâmetros de broadcast. Em uma modalidade alternativa, a mensagem identifica um bloco de bytes correspondente a parâmetros de broadcast. A mensagem pode ser transmitida através de um canal para transmissão de informações de overhead. Para um sistema que suporta um serviço de broadcast, a mensagem identifica uma pilha de protocolo para processamento de serviço de broadcast, a mensagem identifica uma pilha de protocolo para processamento de conteúdo de broadcast.
