Abstract

La presente invención describe los métodos para enviar las señales de referencia de posicionamiento (PRS), para enviar los datos y para recibir los datos; cuando se requiere enviar las PRS y los datos portados por un canal de control físico de enlace descendente (PDCCH) en un mismo recurso físico, únicamente los datos portados por el PDCCH o las PRS se envían en el mismo recurso físico; o, cuando un extremo de envío envía las PRS y los datos portados por el PDCCH en el mismo recurso físico al mismo tiempo, un extremo de recepción se hace para ignorar las PRS recibidas o los datos portados por el PDCCH; o, el envío de las PRS o los datos portados por el PDCCH está limitado para que no se envíen en el mismo recurso físico; la presente invención también describe los dispositivos para enviar datos y recibir datos; la presente invención ha resuelto el problema de que los datos portados por el PDCCH están en conflicto con las PRS sobre el cuarto símbolo de OFDM cuando el PDCCH se envía sobre los primeros cuatro símbolos de OFDM en el subcuadro, con cual asegura el desempeño total del sistema.
