Abstract

"MéTODO PARA TRANSMITIR/RECEBER DADOS EM SISTEMA DE COMUNICAçãO DE DADOS HARQ". Esta invenção refere-se a um método de transmissão/ recepção de dados num sistema de comunicação de dados HARQ. Para transmitir um fluxo de informação de camada física contendo uma série de sub-blocos, cada sub-bloco contendo um código de correção de erro, uma QoS (Qualidade de Serviço) e uma prioridade se os sub-blocos têm uma QoS diferente, a fluxo de informação da cada física codificada é dividido numa série de aberturas. Os dados de aberturas são transmitidos seq³encialmente para um receptor em intervalos predeterminados de tempo. Se uma mensagem de HARQ (Solicitação Automática Hibrida de Repetição) para os dados iniciais de abertura for recebida do receptor, indicando que pelo menos um dos sub-blocos nos dados iniciais de abertura contem um erro de recepção e os outros sub-blocos estão bons na recepção, os dados de abertura com um sub-bloco contendo um erro repetido dentro do número dos sub-blocos são retransmitidos após a transmissão dos dados iniciais de abertura.
