Abstract
Radio frequency (RF) sensing of a target object by a wireless network is supported by a sensing node and a network node using sensing assistance data. The sensing assistance data may include information for Doppler estimation from received RF signals. The information for Doppler estimation, for example, may include an indication of phase coherency of RF signals, such as phase coherence found in positioning reference signal (PRS) resources, resource sets, transmission reception points (TRPs), frequency layer or any combination thereof. The sensing assistance data may include an association of PRS resources and reference point objects (RPOs) so RF signals reflected from the RPOs may be excluded from the sensing measurements. The sensing assistance data may include beam pattern information for PRS resources for beam coordination for RF sensing.
