Abstract
A method and apparatus for transmitting a dedicated reference signal (DRS) are provided, the method including determining, by a base station, whether user equipments (UEs) participating in multiple users-multiple input multiple output (MU-MIMO) at the same physical resource block (PRB) belong to the same cell, if yes, configuring that the UEs adopt a cell-specific scrambling code sequence; otherwise, configuring that the UEs located in the cells belonging to the same cell group adopt a cell group-specific scrambling code sequence; sending, by the base station, configuration information to the UE, and sending a DRS to the UE by using the scrambling code sequence configured for the UE; an initialization code of the cell-specific scrambling code sequence is determined according to an identity of the cell in which the UE is located; an initialization code of the cell group-specific scrambling code sequence is determined according to an identity of the cell group. As such, the UE can restrain DRS interferences between different cells when receiving the DRS and improve the precision of the channel estimation.
