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.

Abstract: The disclosure provides a power adjustment method and apparatus for adjusting power of a serving cell. The serving cell sends a first message to a first terminal to indicates to configure a first measurement bandwidth as a center bandwidth, where a frequency range of the center bandwidth is less than a frequency range of a full bandwidth, the full bandwidth represents a maximum bandwidth allocated to the serving cell, and the first measurement bandwidth is used by the first terminal to measure channel quality; the serving cell reduces power in a second bandwidth, where a frequency range of the second bandwidth is a frequency range obtained by subtracting the frequency range of the center bandwidth from the frequency range of the full bandwidth; and the serving cell increases power in the center bandwidth. The increase of the power in the center bandwidth can increase a coverage of the serving cell.
