Abstract
The integrity and reliability of the positioning information are crucial for applications, including safety-critical ones, that rely on cellular network users' locations. Release 18 of the Third Generation Partnership Project (3GPP) broadens the notion of integrity, which was initially applied only to positioning based on Global Navigation Satellite System (GNSS), to include positioning based on Radio Access Technology (RAT). This paper presents a general 3GPP-compliant framework to assess 5G positioning integrity. The framework is based on uncertainty quantification and is applied to classical time-difference-of-arrival positioning algorithms and to more advanced positioning methods that rely on machine learning. If an integrity alert is raised, error mitigation techniques are also proposed to enable resilient positioning through the selection of reliable network nodes. Results obtained by using a 3GPP-compliant dataset of position estimates in an indoor open-office scenario demonstrate promising detection and resilience capabilities in the presence of integrity breaches.
期刊介绍：
The scope of the Transactions is threefold (which was approved by the IEEE Periodicals Committee in 1967) and is published on the journal website as follows: Communications: The use of mobile radio on land, sea, and air, including cellular radio, two-way radio, and one-way radio, with applications to dispatch and control vehicles, mobile radiotelephone, radio paging, and status monitoring and reporting. Related areas include spectrum usage, component radio equipment such as cavities and antennas, compute control for radio systems, digital modulation and transmission techniques, mobile radio circuit design, radio propagation for vehicular communications, effects of ignition noise and radio frequency interference, and consideration of the vehicle as part of the radio operating environment. Transportation Systems: The use of electronic technology for the control of ground transportation systems including, but not limited to, traffic aid systems; traffic control systems; automatic vehicle identification, location, and monitoring systems; automated transport systems, with single and multiple vehicle control; and moving walkways or people-movers. Vehicular Electronics: The use of electronic or electrical components and systems for control, propulsion, or auxiliary functions, including but not limited to, electronic controls for engineer, drive train, convenience, safety, and other vehicle systems; sensors, actuators, and microprocessors for onboard use; electronic fuel control systems; vehicle electrical components and systems collision avoidance systems; electromagnetic compatibility in the vehicle environment; and electric vehicles and controls.
