Patent ID: 8804549

Claim:
A method for transmitting a dedicated reference signal (DRS), comprising: 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 each of the UEs, and sending a DRS to each of the UEs by using the scrambling code sequence configured for each of the UEs; wherein an initialization code of the cell-specific scrambling code sequence is determined according to an identity of the cell in which each of the UEs are located; an initialization code of the cell group-specific scrambling code sequence is determined according to an identity of the cell group.
