Abstract

"CONFIRMAçãO DE MENSAGENS PERDIDAS DIFUNDIDAS EM UM CANAL DE CONTROLE". Descrevem-se métodos e um equipamento para confirmar o recebimento de mensagens de canal de controle perdidas. Em um sistema no qual as mensagens de canal de controle podem ser utilizadas para enviar os parâmetros de transmissão de sinais em um canal de tráfego de dados, a incapacidade de decodificar a última mensagem de canal de controle pode provocar um retardo no rendimento operacional do sistema. Uma funcionalidade é acrescentada ao canal de confirmação de recebimento que já está no lugar para confirmar o recebimento de sub-pacotes de dados no canal de tráfego de dados, de modo que confirmações de recebimento de mensagens de canal de controle perdidas possam ser difundidas. Um padrão ou vários sinais de confirmação de recebimento podem ser utilizados para solicitar transmissões de mensagens de canal de controle (220). Um elemento de infra-estrutura pode ser configurado para ler os sinais de confirmação de recebimento como uma solicitação de difusão no canal de controle (230).
