Abstract

a presente invenção se refere a métodos, sistemas e dispositivos para comunicação sem fio. um sistema sem fio que utiliza uma ou mais portadoras configuradas para duplicação por divisão do tempo (tdd) pode utilizar uma estrutura de intervalo de tempo de transmissão (tti) dual (por exemplo, em nível de subquadro e nível de símbolo). os tti em nível de símbolo podem ser referidos como ttis de baixa latência (ll) e podem ser organizados dentro de subquadros de ll. um subquadro de ll pode ser um subquadro que é programado para transmissões em uma direção (por exemplo, uplink ou downlink, de acordo com uma configuração tdd) e pode incluir vários símbolos de ll programados para transmissões uplink (ul) e downlink (dl). os períodos de guarda podem ser programados entre símbolos de ll adjacentes que têm direções de transmissão opostas para permitir que o equipamento de usuário (ue) transite do modo receptor para o modo de transmissão (ou vice-versa). os subquadros de ll podem ser transparentes para dispositivos receptores que não suportam operações de ll.
