1. A method of wireless communication performed by a base station (BS), the method comprising:
measuring a sounding reference signal (SRS) transmission transmitted by a user equipment (UE) using a SRS resource, the SRS transmission having a SRS parameter that is (i) indicated in or related to a triggering message, or (ii) related to a transmission parameter of a communication between the BS and the UE, wherein the SRS parameter is related to the transmission parameter of the communication via a RRC configuration message from the BS, wherein the triggering message is configured to override a relationship between the SRS parameter and the transmission parameter; and
receiving, using a receive beam selected based on the measuring, a transmission from the UE.
