Abstract

"MéTODO DE COMUNICAçãO DE CANAL COMUM PARA UM SISTEMA DE COMUNICAçãO CDMA". Método para irradiar informação de canal, de canal disponível e de velocidade de dados de uma estação base em um sistema de comunicação CDMA. A estação base recebe informação que indica que uma estação móvel tem dados a transmitir, por um canal de preâmbulo de acesso. A estação base transmite informação de situação de utilização dos canais físicos e informação da velocidade de dados disponível máxima em um canal indicador de situação. A estação móvel recebe a informação de situação de utilização dos canais físicos e a informação de velocidade de dados disponível máxima através do canal indicador de situação de uma estação base. A estação móvel transmite para a estação base um preâmbulo de acesso para solicitar a alocação de um canal físico dado determinado dependendo da informação de situação de utilização e a informação de velocidade de dados disponível máxima.
