Abstract

"MéTODO DE SOLICITAçãO DE REPETIçãO AUTOMáTICA DE CAMADA FìSICA PARA ESTAçãO BASE. Método de solicitação de repetição automática física implementada por uma estação base (30) que contém um transmissor (38) e um receptor (52). Uma camada física, no transmissor (38), recebe os dados e formata os dados recebidos em pacotes que possuem modulação de dados/codificação específica. A camada física transmite os pacotes e retransmite pacotes em resposta ao não recebimento de reconhecimento (56) correspondente para um dado pacote. Um controlador de codificação e modulação adaptativa no transmissor coleta estatísticas de retransmissão (60) e ajusta a modulação de dados/codificação específica, utilizando as estatísticas coletadas (62).
