METHOD AND APPARATUS FOR WIRELESS COMMUNICATION CHANNEL STATE INFORMATION (CSI) REPORTING
A method and apparatus for wireless communication comprises receiving reporting configuration information, determining, based on the reporting configuration information, a first channel state information (CSI) resource group and a frequency-domain resource, wherein the first CSI resource group comprises at least two CSI resources, determining a CSI set, based on a measurement on the first CSI resource group, and transmitting the CSI set. The reporting configuration information is used for configuring a CSI reporting for the frequency-domain resource, and for each CSI resource in the first CSI resource group, the frequency-domain resource comprises at least one physical resource block (PRB) that does not belong to PRBs across which the CSI resource passes, and PRBs across which any CSI resource in the first CSI resource group passes are contiguous in a frequency domain.
