Abstract

Methods, systems, and devices for wireless communications are described. In some wireless communications systems, a user equipment (UE) may receive signaling scheduling a first set repetitions of a first uplink shared channel transmission associated with a first sounding reference signal (SRS) resource set and a second set of repetitions of a second uplink shared channel transmission associated with a second SRS resource set. The UE may receive a request to transmit one or more channel state information (CSI) reports and an indication that the CSI reports are to be multiplexed with one of the first set of repetitions or the second set of repetitions or with both of the first and second set of repetitions. The UE may then transmit the CSI reports in accordance with the indication by multiplexing the CSI reports with one or both of the first set of repetitions and the second set of repetitions.
