This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for a sounding reference signal (SRS) resource set configuration to facilitate uplink panel selection between a set of asymmetric panels of a user equipment (UE), each panel of the set of asymmetric panels of the UE being associated with a different number of SRS ports. In one aspect, the UE may receive such an SRS resource set configuration indicating one or more SRS resource sets and SRS resources of the one or more SRS resource sets may be associated with different numbers of SRS ports or a dynamically configurable number of SRS ports. The UE may receive control signaling from a base station (BS) and the control signaling may indicate a panel for an uplink transmission from the UE by indicating an SRS resource, an SRS resource set, or a number of SRS ports.
