1. A user equipment (UE) for wireless communication, comprising:
a memory; and one or more processors coupled to the memory, wherein the UE is configured to:
receive configuration information for a sounding reference signal (SRS) resource set, wherein the configuration information indicates a Doppler tracking usage type for the SRS resource set, that the SRS resource set is an aperiodic SRS resource set, a time gap between repetitions of SRS resources of the aperiodic SRS resource set, and a configuration for one or more SRS resource identifiers associated with the SRS resource set;
receive downlink control information (DCI) triggering a transmission of the SRS resource set associated with the one or more SRS resource identifiers, wherein the DCI indicates one or more parameters for the SRS resource set, and wherein the one or more parameters indicate a modified time gap between the repetitions of SRS resources of the aperiodic SRS resource set, and wherein, to receive the DCI, the UE is configured to:
receive a set of values for a start position parameter for a single SRS resource identifier, wherein the set of values include one or more valid values and one or more invalid values; and
transmit the SRS resource set based at least in part on the one or more parameters.
