Methods, systems, and devices for wireless communications are described that provide for refinement of receive beam beamforming parameters at a user equipment (UE). A UE may transmit two or more signals in an uplink transmission that have different beamforming parameters. A base station receiving the uplink transmission may measure the two or more signals, and identify a first signal of the two or more signals based at least in part on the measuring. The base station may inform the UE of the identified first signal, which the UE may use to set receive beam beamforming parameters for one or more subsequent downlink transmissions.
