Abstract:
Provided are a method, device, and system for indicating a channel state information reference signal (CSI-RS) resource. A base station can configure one or more channel state information reference signal (CSI-RS) resources for a plurality of terminals within a cell covered by the base station, and can indicate a CSI-RS resource that can be used by each terminal in the plurality of terminal and belongs to the one or more CSI-RS resources, thereby enabling each terminal to perform measurement and feedback of channel state information according to the CSI-RS resource indicated by the base station by using a physical layer signal or a media access layer signal. In the present scheme, CSI-RS configuration of terminals can be quickly and flexibly changed by introducing a physical layer signal or a media access layer signal, thereby reducing overheads of CSI-RS without affecting system performance.
