Transmission power allocation method and device for the demodulation reference signal

The present invention discloses a method for configuring a transmission power demodulation reference signal, comprising: resource allocation means in each RE transmission power ratio data demodulation reference signal DMRS and the transmission power of the corresponding layer at a constant value. The present invention also discloses a transmission power reference signal configuration for demodulating means. The present invention greatly improves the accuracy of the decoded data frame, decoding performance is improved. The present invention is no longer necessary to make the network side correspondence relationship between each transmission power of the DMRS of the corresponding layer to a user terminal, thereby simplifying the control signaling overhead of the network side. Since the correspondence between the transmission power of the DMRS of the data layers are arranged in the user terminal, without waiting for the user terminal notifies the network side of the channel estimation can be achieved, improving the efficiency of channel estimation.
