Abstract

La presente invención proporciona un método y dispositivo para transmitir una secuencia de señal de referencia; el método incluye: determinar una posición de un eCCE o un eREG mapeados a un ePDCCH en un par de bloques de recursos; determinar, de acuerdo con la relación correspondiente entre la posición del eCCE o el eREG en el par de bloques de recursos y el puerto de antena de la señal de referencia; y transmitir una secuencia de referencia sobre el puerto de antena de la señal de referencia, aquí, la relación correspondiente entre la posición del eCCE o el eREG en el par de bloques de recursos y el puerto de antena de la señal de referencia incluye que las posiciones de al menos dos eCCEs o al menos dos eREGs corresponden a uno de los puertos de antena de la señal de referencia; la solución técnica proporcionada en las modalidades de la presente invención puede resolver el problema de que la capacidad de ejecutar estimación de canal para un ePDCCH utilizando una secuencia de señal de referencia se reduce debido a que la secuencia de señal de referencia no puede ser transmitida a través de un puerto de antena en el caso en que el número de los puertos de antena sea limitado.
