Abstract
métodos realizados por um equipamento de usuário e por uma estação base, e, dispositivo sem fio. um método para diferenciar múltiplos esquemas de transmissão de canal compartilhado em enlace descendente físico (pdsch). em um exemplo não limitante, os esquemas de transmissão pdsch incluem um esquema de transmissão com multiplexação espacial, um esquema de transmissão com multiplexação de frequência, um esquema de transmissão com multiplexação de tempo com base em intervalo, e um esquema de transmissão com multiplexação de tempo com base em mini-intervalo. em exemplos aqui discutidos, um equipamento de usuário (ue) pode ser configurado para diferenciar os esquemas de transmissão pdsch com base em informação indicada na informação de controle de enlace descendente (dci) para agendamento de uma transmissão pdsch, informação sinalizada para o ue por meio de uma configuração de camada superior, e/ou sinalização de capacidade indicada do ue para uma rede. pela diferenciação dos esquemas de transmissão pdsch, o ue pode receber eficientemente uma transmissão de dados(s) a partir de múltiplos pontos de transmissão/recepção (trps).
