Abstract

Se divulga un método para transmitir una señal de referencia y un dispositivo de comunicación; el método es ejecutable mediante un dispositivo terminal o un dispositivo de red, y comprende: determinar al menos una unidad de recurso de dominio del tiempo para transmitir una señal de referencia; y transmitir la señal de referencia en la al menos una unidad de recurso de dominio del tiempo; dado que la señal de referencia se transmite en la al menos una unidad de recurso de dominio del tiempo específica, en lugar de transmitirse reutilizando una parte de las subportadoras de una unidad de recurso de dominio del tiempo para la transmisión de datos, se reduce el retraso en la transmisión de la señal de referencia, reduciendo así la demora en la demodulación de datos o la medición de CSI realizada en base a la señal de referencia, y reduciendo la sobrecarga de señalización de control para indicar un recurso de correspondencia de tasa y la complejidad de realizar la correspondencia de tasa.
