Csi and calibration reporting

A base station (BS) comprising:

• a processor;
• and
• a transceiver operably coupled to the processor, the transceiver configured to:
• transmit, to a user equipment (UE), information related to first and second channel state information (CSI) reports, wherein:
• the information for the first CSI report indicates (i) NTRP CSI reference signal (CSI-RS) resource sets, NTRP>1, and (ii) a report quantity set to ‘cjtc-Dd’,
• the information for the second CSI report indicates (i) NTRP CSI-RS resources, (ii) a report quantity set to ‘cri-RI-PMI-CQI’, and (iii) a codebook type set to ‘typeII-CJT-r18’, and
• the first CSI report is linked to the second CSI report via a radio resource control (RRC) parameter, and
• receive, from the UE, the second CSI report including a CSI that is based on the information.

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

• receiving information related to first and second channel state information (CSI) reports, wherein:
• the information for the first CSI report indicates (i) NTRP CSI reference signal (CSI-RS) resource sets, NTRP>1, and (ii) a report quantity set to ‘cjtc-Dd’,
• the information for the second CSI report indicates (i) NTRP CSI-RS resources, (ii) a report quantity set to ‘cri-RI-PMI-CQI’, and (iii) a codebook type set to ‘typeII-CJT-r18’, and
• the first CSI report is linked to the second CSI report via a radio resource control (RRC) parameter;
• determining, based on the information, a CSI for the second CSI report;
• and
• transmitting the second CSI report including the CSI.
