Abstract

"MéTODO, EQUIPAMENTO E SISTEMA PARA MULTIPLEXAçãO DE USUáRIO EM SISTEMAS DE ACESSO MúLTIPLO COM RETRANSMISSãO". De acordo com um aspecto da invenção, é provido um método no qual um grupo de usuários em um sistema que emprega um mecanismo de retransmissão tal como a requisição de repetição automática (ARQ) é dividido em múltiplos subgrupos de usuários. A cada usuário são designados diversos canais para transmissão de informações. O número de canais designados para cada usuário é determinado com base, pelo menos em parte, no número dos subgrupos e um número de canais disponíveis no sistema. Os intervalos de transmissão são alternados entre os múltiplos subgrupos tal que apenas a um dos subgrupos de usuários é permitido transmitir informações durante qualquer intervalo de transmissão. Um intervalo inativo durante o qual um usuário específico no primeiro grupo não transmite informações é usado como um período de espera por confirmação de uma transmissão prévia pelo usuário específico.
