Abstract

A first sensing entity may receive, from a second sensing entity, a sensing information message that may include a first set of sensing attributes associated with a set of objects within an area associated with the first sensing entity. The first sensing entity may transmit a set of sensing signals at a target object. The first sensing entity may receive a set of reflected sensing signals based on the set of sensing signals and the target object. The first sensing entity may measure a second set of sensing attributes associated with the target object based on the set of reflected sensing signals and the first set of sensing attributes. The measured second set of sensing attributes may be more accurate than a set of sensing attributes that are not based on the first set of sensing attributes.
