1. A method for updating a RF sensing map based on cellular radio frequency (RF) sensing comprising:
obtaining, from a first vehicle, a first set of cellular RF sensing data of an environment surrounding the first vehicle;
determining a unified cellular RF sensing map based on unifying the first set of cellular RF sensing data with a second set of cellular RF sensing data, wherein the second set of cellular RF sensing data is obtained from a second vehicle; and
updating a RF sensing map, corresponding to the environment surrounding the first vehicle based on the unified cellular RF sensing map, responsive to a determination that a match between the unified cellular RF sensing map and the RF sensing map is below a predetermined threshold.
