Abstract

PROJETO DE OFDM DE NUMEROLOGIA MISTA. A presente invenção se refere a métodos, sistemas e dispositivos para suportar comunicações hierárquicas e de baixa latência dentro de um sistema de comunicação sem fio. Um eNB e/ou um UE pode ser configurado para operar dentro do sistema de comunicações sem fio que é pelo menos parcialmente definido através de uma primeira camada com transmissões em primeira camada tendo um primeiro tipo de subquadro e uma segunda camada com transmissões em segunda camada tendo um segundo tipo de subquadro. O primeiro tipo de subquadro pode ter um primeiro tempo de ida e volta (RTT) entre transmissão e reconhecimento de recebimento da transmissão, e a segunda camada pode ter um segundo RTT que é menor do que o primeiro RTT. Subquadros do primeiro tipo de subquadro podem ser multiplexados com subquadros do segundo tipo de subquadro, tal como através de multiplexação por divisão de tempo. Em alguns exemplos símbolos de duração diferente podem ser multiplexados de maneira que durações de símbolo diferentes coexistem.
