Abstract: Systems and methods for improving testing and/or calibration efficiency of radio frequency system. In some embodiments, a testing system includes a beamformer radio frequency system, in which the beamformer radio frequency system includes first transceiver circuitry and a first plurality of antennas coupled to the first transceiver circuitry, a beamformee radio frequency system, in which the beamformee radio frequency system includes second transceiver circuitry and a second plurality of antennas coupled to the second transceiver circuitry, one or more wired connections coupled between the first transceiver circuitry of the beamformer radio frequency system and the second transceiver circuitry of the beamformee radio frequency system, in which each of the one or more wired connections bypasses the first plurality of antennas of the first radio frequency system and the second plurality of antennas of the second radio frequency system.

Abstract: Embodiments are presented herein of apparatuses, systems, and methods for a wireless device to perform multiple-input, multiple-output (MIMO) transmissions using a reduced number of antennas (e.g., a number of transmit antennas that is smaller than a number of layers of the MIMO transmission). The MIMO transmission may communicate multiple streams of data to a second wireless device. The MIMO transmission may further be used for sensing applications, e.g., based on reflection of the MIMO transmission.
