TRANSMISSION POWER CONFIGURATION METHOD AND APPARATUS FOR DEMODULATION REFERENCE SIGNAL

摘要

A transmission power configuration method for a Demodulation Reference Signal (DMRS) is disclosed by the present invention, which includes that the ratio between the transmission power of the DMRS in each layer in a Resource Element (RE) and the transmission power of the data in a corresponding layer is configured to be a constant value. Meanwhile, a transmission power configuration apparatus for the DMRS is disclosed by the present invention. The present invention greatly improves the correct rate of the data frame decoding, and improves the decoding performance. The present invention enables the network side not need to notify a user terminal of the corresponding relationship between the transmission power of the DMRS in each layer and the transmission power of the data in the corresponding layer, which simplifies the overhead of the control signaling in the network side. As the corresponding relationship between the transmission power of the DMRS and the transmission power of the data in each layer is configured in the user terminal, the user terminal can implement channel estimation without having to wait for the notification from the network side, which improves the channel estimation efficiency.
