Abstract

um método e sistema incluem implantar, por uma estação-base (bs), um mecanismo de transmissão de latência ultra-baixa confiável em um esquema de transmissão de enlace ascendente livre de concessão que possui regiões de acesso de unidade de transmissão de contenção (ctu) definidas nas mesmas e uma pluralidade de ctus. implantar o mecanismo de transmissão de latência ultra baixa confiável inclui definir uma região de acesso de ctu de latência ultra-baixa confiável (rull-ctu) a partir de uma parte das regiões de acesso de ctu do esquema de transmissão livre de concessão, definir um esquema de mapeamento rull-ctu por mapeamento de pelo menos uma porção da pluralidade de ctus para a região de acesso de rull-ctu para definir uma pluralidade de rull-ctus, definir um esquema de mapeamento de equipamento de usuário de latência ultra-baixa confiável (rull-ue) por definição de regras para mapear uma pluralidade de rull-ues para a pluralidade de rull-ctus em um padrão inicial para transmissões iniciais em um primeiro intervalo de tempo de transmissão (tti) e um padrão reagrupado para transmissões redundantes em um segundo tti subsequente ao primeiro tti.
