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.
