Systems and methods for improving positioning with error source modeling
Presented are systems and methods for positioning. A method includes sending, by a core network entity to a first wireless communication entity, a first message including measurement and/or assistance data for positioning, wherein the assistance data includes no or one or more characteristic parameters associated with a model of an error source. Another method includes receiving, by a core network entity from a second wireless communication entity, a second message including assistance data for positioning, wherein the assistance data includes one or more characteristic parameters associated with a model of an error source.
