Method and apparatus for CSI report configuration for CSI predictions in one or more domains

A base station (BS), comprising:

• a transceiver configured to:
• receive, from a user equipment (UE), capability information indicating capability of the UE to support machine learning (ML) based channel state information (CSI) prediction in one or more domains, wherein the one or more domains include a temporal domain,
• transmit configuration information that indicates parameters for the ML based CSI prediction in the one or more domains, wherein the parameters include a time interval between CSI measurements and a duration of a window of CSI measurements,
• transmit CSI reference signals (RSs), and
• receive a CSI report including one or more CSI predictions of a plurality of CSI predictions and a differential temporal CSI prediction,
• wherein the plurality of CSI predictions and the differential temporal CSI prediction are based on the configuration information and the CSI-RSS,
• wherein the plurality of CSI predictions correspond to the time interval and the duration of the window, and
• wherein the differential temporal CSI prediction is determined based on differences between CSI predictions.

A method performed by a user equipment (UE), the method comprising:

• transmitting capability information indicating capability of the UE to support machine learning (ML) based channel state information (CSI) prediction in one or more domains, wherein the one or more domains include a temporal domain;
• receiving configuration information that indicates parameters for the ML based CSI prediction in the one or more domains, wherein the parameters include a time interval between CSI measurements and a duration of a window of CSI measurements;
• receiving CSI reference signals (RSS);
• measuring the CSI-RSs;
• determining, based on the configuration information and the measured CSI-RSs, (i) a plurality of CSI predictions in the one or more domains, the determined plurality of CSI predictions corresponding to the time interval and the duration of the window and (ii) a differential temporal CSI prediction based on differences between CSI predictions;
• determining a CSI report including one or more of the plurality of CSI predictions;
• and
• transmitting the CSI report including the differential temporal CSI prediction.
