Abstract

sistema, aparelho e método de comunicação sem fio,e, programa de computador. em um sistema de comunicação sem fio onde transmissão de pacote começa depois que um processo de preparação é executado entre uma fonte e um destino , a fonte armazena, em um cabeçalho de um pacote de preparação , primeira informação de duração corresponde a um fim de um primeiro pacote de resposta enviado do destino e segunda informação de duração correspondendo a um fim de um segundo pacote de resposta enviado do destino. uma estação vizinha tendo recebido o pacote de preparação fixa um primeiro nav relativo a um tempo de conclusão de recepção programado do primeiro pacote de resposta baseado na primeira informação de duração e um segundo nav relativo a um tempo de conclusão de recepção programado do segundo pacote de resposta baseado na segunda informação de duração e ignora o segundo nav quando nenhuma transmissão de pacote é detectada dentro do primeiro período de nav ou dentro de um tempo predeterminado depois do tempo de conclusão de recepção programado do primeiro pacote de resposta.
