1. A method of wireless communication performed by a user equipment (UE), comprising:identifying a carrier aggregation (CA) configuration and an aperiodic sounding reference signal (A-SRS) configuration of the UE, the CA configuration comprising one or more component carriers (CCs) on which the UE is configured to perform uplink (UL) data transmissions and the A-SRS configuration comprising one or more CCs on which the UE is configured to transmit A-SRS and not perform UL data transmissions;
receiving a resource assignment on a downlink (DL) CC in the CA configuration, the resource assignment comprising a sounding reference signal radio network temporary identifier (SRS-RNTI);
detecting a trigger based at least in part on the SRS-RNTI, wherein the SRS-RNTI triggers a plurality of A-SRS transmissions in a plurality of UL resources of the A-SRS configuration;
determining at least one CC of the one or more CCs of the A-SRS configuration for transmitting one or more A-SRS transmissions based at least in part on a downlink control information (DCI) of the resource assignment; and
transmitting the one or more A-SRS transmissions on the determined at least one CC of the one or more CCs of the A-SRS configuration.
