Abstract

MÉTODO E APARELHO PARA GERAR SINAIS DE REFERENCIA PARA DIFERENÇA DE TEMPO PRECISA EM ESTIMATIVA DE CHEGADA. A estação base transmite um sinal de referência de posicionamento (PRS) para dispositivos de comunicação sem fio ao longo de um enlace de descida em um sistema de comunicação sem fio através da codificação de um PRS em um primeiro conjunto de recursos de transmissão, codificação de outras informações em um segundo conjunto de recursos de transmissão, multiplexação dos dois conjuntos de recursos em um subquadro de tal forma que o primeiro conjunto de recursos é multiplexado em pelo menos uma porção de um primeiro conjunto de símbolos multiplexados por divisão de frequência ortogonal (OFDM) com base em um identificador associado com a estação base e o segundo conjunto de recursos multiplexado em um segundo conjunto de símbolos OFDM. Ao receber o subquadro, um dispositivo de comunicação sem fio determina qual conjunto de recursos de transmissão contém o PRS com base no identificador associado com a estação base que transmitia o subquadro e processa o conjunto de recursos que contém o PRS para estimar a informação de tempo (por exemplo, o tempo de chegada).
