The present invention provides a method and device for transmitting a demodulation reference signal. The method comprises: a first device determines a location for sending a demodulation reference signal in a physical resource block, the location for sending the demodulation reference signal comprising a mapping location of a channel state information reference signal (CSI-RS) that is used and/or not used by the first device, and the demodulation reference signal being used for demodulating data of a second user equipment; the first device sends configuration information to the second user equipment, the configuration information being used for indicating the location of the demodulation reference signal in the physical resource block; and the first device sends the demodulation reference signal at the location for sending the demodulation reference signal in the physical resource block. By using the technical scheme provided in an embodiment of the present invention, demodulation of downlink user data of more users can be supported. |
