In some wireless communications systems, a user equipment (UE) may receive, from a base station, downlink control information (DCI) that activates periodic channel state information (CSI) reporting via uplink shared channel transmissions (e.g., via physical uplink shared channel (PUSCH) transmissions). The UE may then identify a trigger condition that triggers a transmission of both a first instance of a CSI report and a second instance of the CSI report within a period of the periodic CSI reporting. Based on the satisfaction of the trigger condition, the UE may transmit the first instance of the CSI report via a first uplink shared channel transmission and the second instance of the CSI report via a second uplink shared channel transmission, where both uplink channel transmissions are within the period of the periodic CSI reporting.
