Abstract
Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit a capability message indicating a first number of one or more transmit antennas supported by the UE for antenna switching and a second number of ports supported for uplink transmission that exceeds the first number of one or more transmit antennas. The UE may receive, based on the capability message, a sounding reference signal (SRS) configuration indicating a mapping between each SRS resource or SRS resource group and a respective bit sequence of a set of bit sequences. The UE may receive a control message comprising one or more bit sequences of the set of bit sequences indicating one or more SRS resources or an SRS resource group based on the mapping. The UE may transmit one or more SRS signals based on the control message.
