Abstract

método para acesso de canal de modo direto. um método para acesso de canal de modo direto em um sistema de acesso múltiplo por divisão de tempo (tdma) inclui: a atribuição de uma operação de rádio no sistema tdma para transmissão em um primeiro intervalo de tempo de um canal de modo direto; a inciação de um pedido para uma transmissão de modo direto no canal de modo direto; a determinação pelo rádio, se atividade de comunicação está presente no primeiro intervalo de tempo ou em um segundo intervalo de tempo do canal de modo direto; o alinhamento, pelo rádio, para um intervalo de temporização selecionado com base na etapa de determinação; e a transmissão, por rádio, com o intervalo de temporização selecionado no primeiro intervalo de tempo.
