1. A channel state information (CSI) report configuration method, performed by a terminal device, and the method comprising:
receiving a CSI report configuration and at least one CSI resource configuration, wherein the CSI resource configuration indicates a CSI resource set that comprises multiple CSI resource subsets, wherein the multiple CSI resource subsets correspond to quasi co-located (QCL) CSI resources with different spatial properties respectively, wherein configuration information for configuring the multiple CSI resource subsets indicates a quantity of the multiple CSI resource subsets or a quantity of CSI resources in each CSI resource subset;
determining a CSI report based on the CSI report configuration and the at least one CSI resource configuration, wherein the CSI report comprises report information determined based on the multiple CSI resource subsets, wherein the CSI report includes one group of channel state information-reference resource indices (CRIs), CSI resource quality corresponding to the one group of CRIs, multiple precoding matrix indicators (PMIs) corresponding to the one group of CRIs respectively, and multiple rank indicators fills) corresponding to the multiple PMIs respectively; and
sending the CSI report.
