Abstract: Embodiments provide a CSI-RS sending method and device, and a base station. The CSI-RS sending method includes: receiving capability indication information of each user equipment UE in a cell; determining N transmission schemes based on the capability indication information; configuring CSI-RS resources to be multiplexed by CSI-RSs corresponding to the N transmission schemes; and sending, to corresponding UE based on each of the N transmission schemes, a CSI-RS that is carried on the CSI-RS resource and that corresponds to the corresponding transmission scheme. It can be learned that according to the technical solutions in the embodiments of this application, when resources are limited, CSI-RSs corresponding to different transmission schemes are sent in a resource multiplexing manner, so that a plurality of transmission schemes can be compatible, and resource utilization can be improved.
