A method, a device, and a system for sending reference signals (RSs) are provided, which are capable of least modifying an original system and controlling the system overhead of the RSs. The method includes: grouping expanded transmitting antennas, wherein each group includes two transmitting antenna ports; and in two adjacent RS periods 2T, the RSs sent through the two transmitting antenna ports of each group are [a*s1, b*s1*ejw] respectively in a first period T and [a*s2, -b*s2*ejw] respectively in a second period T. The method, the device, and the system for sending RSs are applicable in design of transmitting antennas of an LTE Advanced system. |
