Abstract

"MéTODO E EQUIPAMENTO PARA AUMENTAR ARQ DE CAMADA FìSICA EM UM SISTEMA DE COMUNICAçãO DE DADOS SEM FIO". Trata-se de um sistema (100) e de diversos métodos e equipamentos para comunicação eficaz de dados através de diversas camadas de protocolos. Um sistema de controle e transceptor (1400) é configurado para determinar um valor de controle de taxa de dados (DRC) e para transmitir um número máximo de partições de tempo para transmissão de um pacote de dados da camada física (510) . Após a detecção do término normal da transmissão, os limites de decodificação (401, 402) são ajustados para a decodificação de uma mensagem de confirmação positiva e a repetição da decodificação de um canal de confirmação (340) com os limites ajustados (401 e 402) . A retransmissão do pacote de dados da camada física pelo menos uma vez mais após, com base na repetição da decodificação do canal de confirmação (340) produzir ou não uma mensagem de confirmação negativa. A retransmissão pode ser condicionada pelo nível de a capacidade de transmissão das comunicações entre a estação base e a estação móvel.
