Disclosed are a method and a base station for configuring a channel status information reference signal. The method comprises: obtaining location information of a user equipment; based on the location information, determining that the user equipment is located in a cross coverage region where at least two nodes provide services or in a centralized coverage region where one node provides services; when determining that the user equipment is located in the cross coverage region, determining a number of ports for sending downlink signals to the user equipment based on a transmission capability of the at least two nodes and a receiving capability of the user equipment; and sending CSI-RS configuration information to the user equipment, wherein the CSI-RS configuration information comprises the number of ports. In embodiments of the present invention, the method and the base station for configuring the channel status information reference signal determine the number of ports for sending the downlink signals to the user equipment based on the transmission capability of a node and the receiving capability of the user equipment, and thereby a CSI-RS can be configured at a user level, throughput can be further improved, coverage is enhanced, and user experience can be improved. |
