Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit a first capability message to a network entity indicating that the UE may be capable of using a subset of antenna ports of a set of antenna ports for uplink sounding on a wireless band. Further, one or more antenna ports of the set of antenna ports may be available for the uplink sounding and the first capability message may include an indication of the set of antenna ports. The UE may then receive control signaling from the network entity indicating the subset of antenna ports that the UE should use for the uplink sounding based on the first capability message. As such, as part of the uplink sounding on the wireless band, the UE may transmit one or more sounding reference signals (SRSs) via the subset of antenna ports indicated by the control signaling.
