| 摘要 |
Embodiments of the present disclosure provide a method for configuring demodulation reference signals, a method for mapping demodulation reference signals ,a method for performing channel estimation and apparatus thereof. The method includes: configuring demodulation reference signals (DMRSs) being carried by four orthogonal frequency division multiplexing (OFDM) symbols in one physical resource block (PRB) pair; wherein the four OFDM symbols are divided into two groups, each group consisting of two adjacent OFDM symbols, and the distance between the two groups of OFDM symbols being greater than five OFDM symbols. With the method and apparatus of the embodiments of the present disclosure, performance of channel estimation based on DMRSs in advanced releases of LTE (Release 12 or higher) may be improved. |
