Abstract

mapeamento de um preâmbulo para múltiplas unidades de recurso de canal físico compartilhado de uplink para procedimento de acesso aleatório de duas etapas. aspectos são fornecidos para suportar cargas úteis para transmissão de msga em um procedimento de acesso aleatório (rach) de duas etapas fornecendo um arranjo de mapeamento um para muitos entre preâmbulos e unidades de recurso de canal físico compartilhado de uplink (pusch)(prus). um preâmbulo é determinado pelo ue, que é mapeado para um ou mais grupos de prus para suportar piggyback de informações de controle de uplink (uci), salto de frequência em pusch e repetição de múltiplas partições para transmissões de msga. ao realizar piggyback de uci para uma carga útil em msga, flexibilidade pode ser fornecida na seleção de mcs e forma de onda, bem como alocação de recurso para sinais de referência de demodulação (dmrs) e pusch em prus. além disso, ao permitir salto de uma carga útil para diferentes frequências em pusch durante a transmissão de msga, um ganho em diversidade de frequência e em média de interferência pode ser fornecido, e ao permitir que uma carga útil seja repetida em múltiplas partições na transmissão de msga, aprimoramento e/ou confiabilidade de cobertura podem ser aumentados.
