Disclosed are techniques for radio frequency (RF) sensing. In an aspect, a network entity (e.g., base station or road-side unit) may perform RF sensing in a first mode for sensing a horizontal angle using horizontal multiple input, multiple output (MIMO) radar with vertical beamforming, in which a two-dimensional MIMO antenna array is configured into a plurality of vertical columns, each column comprising a plurality of antenna elements configured to transmit as a phased array, each column transmitting a different orthogonal signal from the other columns. The network entity may perform RF sensing in a second mode for sensing a vertical angle using vertical MIMO radar with horizontal beamforming, in which the MIMO antenna array is configured into a plurality of horizontal rows, each row comprising a plurality of antenna elements configured to transmit as a phased array, each row transmitting a different orthogonal signal from the other rows.
A method for radio frequency (RF) sensing performed by a network entity that controls a two-dimensional (2D) multiple input, multiple output (MIMO) antenna array having a vertical dimension and a horizontal dimension, the method comprising:
A network entity, comprising:
