Abstract
The invention claims method and device for transmitting special reference signal (DRS) the method comprises the following steps: a base station determines whether the UEs participating in multiple user-multiple input multiple output(MU-MIMO) at the same physical resource block (B) belong to the same cell; if so allocating the UEs to adopt a specific cell scrambling code sequence; if not allocating the UEs in the same cell groups to use specific cell group scrambling code sequence; said base station sends the allocation information to the UE and sends the special reference signal (DRS) to the UE according to the scrambling code sequence allocated to the UE wherein the initial code of the specific cell scrambling code sequence is determined by the mark of the cell of the UE; the specific cell group scrambling code sequence is determined by the mark of the cell group. The invention enables the UEto restrain DRS interferences between different cells when receiving the DRS and improve the precision of the channel estimation.
