Abstract

"APARELHO DE TRANSMISSãO PARA UM SISTEMA DE COMUNICAçãO SEM FIO, UNIDADE MóVEL PARA UM SISTEMA DE COMUNICAçãO SEM FIO, E, PROCESSO PARA TRANSMITIR PACOTES DE DADOS EM UM SISTEMA DE COMUNICAçãO SEM FIO" Para obter uma utilização melhorada de um canal de enlace rádio em um sistema de transmissão sem fio orientado por pacotes, pacotes de dados são trasmitidos entre um aparelho de transmissão (10) e uma unidade móvel (14), respectivamente. Então é determinado se uma transmissão de pacotes de dados entre o aparelho de transmissão (10) e a unidade móvel (14) foi realizada com sucesso. Aqui, um canal de transmissão (16) é redesignado a uma outra unidade móvel (14) em um caso em que é determinado que a transmissão do pacote de dados não foi bem sucedida, e adicionalmente uma retransmissão de um pacote de dados é estimada como sendo não bem sucedida.
