## Abstract

Methods, systems, and devices for wireless communications are described to support determination of an uplink beam for uplink transmissions. A base station may configure a user equipment (UE) with multiple sets of sounding reference signal (SRS) resources that may be used for uplink transmissions from the UE. In some cases, each set of SRS resources may be configured with one associated channel state information reference signal (CSI-RS) resource, and each CSI-RS resource may correspond to an uplink beam. The base station may transmit a downlink control message to the UE, indicating one or more selected SRS resource sets and one or more selected SRS resources within each of the one or more selected SRS resource sets. The UE may transmit an uplink transmission with a beam associated with the indicated SRS resource set.
