1. A method of wireless communication, performed by a user equipment (UE), the method comprising:
receiving a plurality of channel state information (CSI) requests for CSI reporting for one or more component carriers (CCs);
identifying one or more unreported CSI requests of the plurality of CSI requests, wherein the one or more unreported CSI requests are determined before a current CSI triggering subframe;
determining a total number of CSI-reference signal (RS) antenna ports combined across all of the unreported CSI requests, wherein the total number of CSI-RS antenna ports is determined per CC of the one or more CCs or over all of the one or more CCs; and
performing CSI feedback relaxation for one or more of the CSI requests of the plurality of CSI requests in response to the total number of CSI-RS antenna ports for the unreported CSI requests exceeding a triggering threshold.
