[0027] The technical solution of the present invention will be further described in detail below in conjunction with the drawings and specific embodiments.
[0028] A method for transmitting channel measurement pilot CSI-RS in the LTE-A system. The CSI-RS of each antenna port currently used is transmitted on the shared resources of LTE and LTE-A users, of which there is at least one antenna The CSI-RS of the port is transmitted according to the common pilot (CRS) transmission method in the existing LTE (Long-Term Evolution) system, except for these antenna ports that transmit CSI-RS according to the CRS transmission method in the LTE system CSI-RS of other antenna ports can be sent on PDSCH (downlink physical shared channel) or PDCCH (downlink physical control channel). Wherein, the number of antenna ports currently used can be 1, 2, 4, 6, or 8.
[0029] In the above method, the network side can transmit the CSI-RS of the antenna port completely according to the CRS transmission meth
