1. A method performed by a sensing node in a wireless network for supporting radio frequency (RF) sensing in the wireless network, comprising:

receiving sensing assistance data from a network node comprising information for Doppler estimation from RF signals, the RF signals comprising positioning reference signals (PRS), and the information for Doppler estimation comprising an indication of phase coherency of the PRS;

receiving the RF signals; and

performing a Doppler estimation using the RF signals and the sensing assistance data.
