摘要： The present disclosure discloses a transmission power configuration method for a Demodulation Reference Signal (DMRS), and the method comprises: configuring the ratio between transmission power of a DMRS at each layer in a Resource Element (RE) and transmission power of data at a corresponding layer to be a constant value. Meanwhile, the present disclosure discloses a transmission power configuration apparatus for the DMRS. The present disclosure greatly improves the correct rate of data frame decoding, and improves decoding performance. The present disclosure enables the network side not need to notify a UE of the corresponding relationship between transmission power of DMRS at each layer and transmission power of data at the corresponding layer, which simplifies the overhead of the control signalling in the network side. As the corresponding relationship between transmission power of DMRS at each layer and transmission power of data at the corresponding layer is configured in the UE, the UE can implement channel estimation without waiting for the notification from the network side, which improves the channel estimation efficiency.
