1. A method for wireless communication at a user equipment (UE), comprising:
transmitting a capability message indicating that the UE supports remaining tuned to a first carrier to transmit multiple sounding reference signals (SRSs) over multiple symbols within a slot, wherein the first carrier is different from a second carrier on which the UE communicates with a network device during the slot;
receiving a control message that indicates an SRS configuration for the UE to transmit SRSs on the first carrier over multiple symbols within a first slot;
tuning to the first carrier in accordance with the control message; and
transmitting the SRSs over the multiple symbols within the first slot on the first carrier before tuning back to the second carrier based at least in part on the capability message.
