Methods, systems, and devices for wireless communications that support coordinated beamforming in millimeter wave (mmW) systems. A user equipment (UE) may indicate a number of supported antennas for signal reception. A plurality of transmission-reception points (TRxPs) may coordinate a beam training with the supported antennas, in determining a beam estimation for coordinated reception at the UE. The coordinated beam training may be carried over combined beams of the associated TRxPs, and may be based on co-phasing factors within a single antenna panel for each of the TRxPs. Based on the coordinated beam training, the UE may determine a matched filtering beam estimate for reception and receive coordinated beamformed transmissions from the plurality of TRxPs as part of coordinated multipoint (CoMP) transmissions.
