Wireless communications systems and methods related to dynamically configuring sounding reference signal (SRS) resources are provided. In some aspects, a base station may measure a SRS transmission transmitted by a user equipment (UE) and receive, using a receive beam selected based on the measuring, a transmission from the UE. In some aspects, a UE may transmit a SRS transmission; and receive, from the BS, a downlink control information (DCI) message including a SRS resource indicator (SRI) for use by the UE in selecting a beam to transmit to the BS. The SRS transmission may be transmitted using a SRS resource and may have a SRS parameter that is indicated in or related to a triggering message, or related to a transmission parameter of a communication between the BS and the UE.
