Abstract

The present disclosure relates to a communication method, a network device, a terminal, a communication system, and a storage medium. The method is executed by a network device, and comprises: configuring a plurality of channel state information reference signal (CSI-RS) resources, wherein the plurality of CSI-RS resources are used for performing channel measurement on M antenna ports of a terminal, and M is greater than 32; configuring codebook subset restrictions (CBSRs) for at least two of the plurality of CSI-RS resources, the CBSRs being used for indicating beam restrictions corresponding to the restricted CSI-RS resources; and sending a first indication to the terminal, wherein the first indication is used for indicating at least one piece of the following configuration information: CSI-RS resources for which CBSRs are configured; CSI-RS resources for which CBSRs are not configured; and CBSRs corresponding to the restricted CSI-RS resources. The use of the method can improve the system efficiency, enhance the coverage range, and reduce the downlink signaling overhead.
