Abstract

considerações de projeto para uma resposta de acesso aleatório para um procedimento de acesso aleatório de duas etapas. trata-se de vários aspectos da presente revelação que se referem, em geral, à comunicação sem fio. um equipamento de usuário (ue) pode transmitir uma mensagem de acesso aleatório incluindo um preâmbulo e uma carga útil. uma estação-base pode detectar o preâmbulo da mensagem de acesso aleatório e pode falhar ou ter sucesso na decodificação da carga útil da mensagem de acesso aleatório. a estação-base pode transmitir, com base pelo menos em parte na detecção do preâmbulo e no resultado de decodificação diferente para a carga útil, uma resposta de acesso aleatório. a resposta de acesso aleatório pode incluir uma concessão de grupo de enlace ascendente e uma indicação para um tipo da concessão de grupo de enlace ascendente para uma pluralidade de ues cujas transmissões de preâmbulo compartilham a mesma ocasião de tempo e frequência. os ues podem monitorar o tipo e os conteúdos da concessão de grupo de enlace ascendente e transmitir subsequentemente dados em um conjunto de recursos de tempo e frequência compartilhados. outros inúmeros aspectos são fornecidos.
