Abstract
A method executed by a first base station in this application includes: determining target pilot ports and a coordinating cell of a target cell, where the coordinating cell is a cell that jointly sends, with the target cell, channel state information-reference signals CSI-RSs of the target cell, the target pilot ports are pilot ports used to jointly send the CSI-RSs of the target cell, and the target pilot ports include a pilot port of the target cell and a pilot port of the coordinating cell; determining a resource location of a target time-frequency resource, where the target time-frequency resource is a time-frequency resource used to send the CSI-RSs of the target cell; and sending the CSI-RSs of the target cell to a terminal based on the target time-frequency resource, where signal strength of the terminal is lower than a preset threshold.
