| 摘要 |
The present invention relates to the technical field of communications, and particularly to a CSI-RS transmission method, a network device and a user equipment, which are used to solve the technical problem of serious power waste in transmitting a CSI-RS. In embodiments of the present invention, a CSI-RS is precoded, which is equivalent to that beamforming is performed on the CSI-RS, so that the CSI-RS can be transmitted to the user equipment as accurately as possible, loss of transmit power in the environment is reduced, and utilization rate of the transmit power is improved. |
