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.

摘要： A method for mapping downlink dedicated pilots to resource elements in an Extended Cyclic Prefix frame structure, applied in a long term evolution system, includes the following steps: the first downlink dedicated pilot of each port is mapped to the specific position of a physical resource block; other downlink dedicated pilots of the port are mapping-processed according to the time-domain interval, frequency-domain interval and a preset regulation; the time-domain interval is two or three OFDM symbols, and the frequency-domain interval is two subcarriers of the same time domain. By defining the positions of pilots in the physical resource block, downlink dedicated pilots can obtain the information of all channels when a base station uses a beamforming of more than four antennas. Making the channel information obtained by dedicated pilots contain the real channel information and the process-weight-value of a beamforming, a UE does not need to obtain the transmission-weight-value of a beamforming, thereby avoiding the feedback overhead of beamforming weight-values.
