Abstract
este pedido refere-se a um método de transmissão de dados. o método inclui: receber, em um subquadro, primeiros dados e primeiro (ou primeiros) sinal de referência de demodulação que é enviado por um primeiro dispositivo de lado de rede por meio do uso de n porta (ou portas) de antena, e segundos dados e segundo sinal (ou sinais) de referência de demodulação que é enviado por um segundo dispositivo de lado de rede por meio do uso de m porta (ou portas) de antena, em que recursos de tempo-frequência ocupados pelo primeiro (ou primeiros) sinal de referência de demodulação são diferentes de recursos de tempo-frequência ocupados pelo segundo (ou segundos) sinal de referência de demodulação, e um recurso de tempo-frequência ocupado pelos primeiros dados e que são ocupados pelos segundos dados se sobrepõem pelo menos parcialmente; e realizar processamento de demodulação no dados com base no primeiro (ou primeiros) sinal de referência de demodulação e no segundo (ou segundos) sinal de referência de demodulação. o método de transmissão de dados pode ser aplicado à transmissão/recepção de múltiplos pontos coordenados na qual uma pluralidade de dispositivos de lado de rede que não são quase colocalizados simultaneamente enviam dados para o equipamento de usuário.
