A methods and apparatuses for providing and configuring channel state information (CSI) reports. A method of operating a user equipment includes receiving a channel state information reference signal (CSI-RS) and generating, based on the CSI-RS reception, a first CSI report and a second CSI report.

The method further includes transmitting the first CSI report in a first channel and the second CSI report in a second channel.
