Abstract:
The present disclosure relates to channel state measurement methods and apparatus. One example method includes selecting, by a network device from N channel state information reference signal (CSI-RS) resources, a target CSI-RS resource and a target channel state information-interference measurement (CSI-IM) resource group associated with the target CSI-RS resource, where an ith CSI-RS resource in the N CSI-RS resources is associated with ni CSI-IM resource groups, and a kth CSI-IM resource group in the ni CSI-IM resource groups includes xik CSI-RS resources in the N CSI-RS resources except the ith CSI-RS resource, and sending, by the network device, first indication information by using first signaling, where the first indication information indicates the target CSI-RS resource and the target CSI-IM resource group.
