1. A method for wireless communications by a user equipment (UE), comprising:
receiving, via a first component carrier, control information that triggers transmission of an aperiodic reference signal in a second component carrier;
receiving control signaling that indicates a plurality of configured transmission configuration indicator states for the second component carrier;
identifying a quasi co-location assumption for reception of the aperiodic reference signal in the second component carrier based at least in part on a control resource set not being configured for the second component carrier, the quasi co-location assumption corresponding to a first transmission configuration indicator state that has a lowest identifier in a set of identifiers that correspond to the plurality of configured transmission configuration indicator states; and
receiving the aperiodic reference signal of the second component carrier based at least in part on the quasi co-location assumption.
