Abstract
"MéTODO E EQUIPAMENTO PARA A TRANSMISSãO DE TRáFEGO DE DADOS EM UM CANAL DE COMUNICAçãO SEM FIO". Métodos e equipamento são apresentados para a programação de transmissões de pacotes de dados durante condições de canal ideais. Em um método, as retransmissões de pacote de dados são programadas para transmissão durante condições de canal favoráveis quando a estação remota alvo está se movendo lentamente, mas são programadas para transmissões periódicas quando o alvo está se movendo de forma moderada ou rápida. Em outro método, retardos longos para as retransmissões em um esquema de temporização sensível a canal são eliminados. Em outros métodos, uma combinação de retransmissões periódicas e não periódicas é utilizada para alcançar a taxa de erro de frame desejada.
