Abstract

"SISTEMA DE COMUNICAçãO PARA ESTABELECER COMUNICAçãO DUPLEX ENTRE ESTAçõES MóVEIS E PROCESSO PARA ESTABELECER COMUNICAçãO DUPLEX ENTRE DUAS ESTAçõES MóVEIS'. Trata-se de um sistema e um processo de comunicação de TDMA/TDD, em que o rendimento de comunicação é aumentado permitindo comunicação duplex direta entre as estações móveis que se encontrarem muito próximas umas das outras. O sistema e o processo determinam a faixa de distância entre as estações móveis. Com base na faixa de distância, as unidades de comunicação poderão comunicar umas com as outras num de dois modos, direto ou indireto. Se for determinada uma condição de localização dentro de uma faixa de alcance mútuo, as estações móveis iniciam uma comunicação duplex direta entre as mesmas. De outra forma, comunicam entre as mesmas no modo indireto.
