Special Session at PIMRC 2017

Date: 8-13 October 2017
Location: Montreal, QC, Canada

PIMRC is one of the premier conferences in the wireless research arena and has a long history of bringing together academia, industry and regulatory bodies. Today, it has become one of IEEE Communication Society’s flagship conferences in telecommunications. PIMRC 2017 includes technical sessions, tutorials, workshops, and technology and business panels. The Institute of Electrical and Electronics Engineers (IEEE) is the world’s largest professional association dedicated to advancing technological innovation and excellence for the benefit of humanity. IEEE and its members inspire a global community through IEEE’s highly cited publications, conferences, technology standards, and professional and educational activities.

Evolution and Perspectives of 5G Cellular Localization


In recent years we have seen an explosion of location based services. These services mostly rely on an accuracy performance that was “envisioned” two decades ago when the FCC demanded from the network operators such a performance to determine the whereabouts of 911 callers. Neither dedicated position systems, such as GPS, nor the cellular systems could deliver the potential performance in indoor or urban canyons, and therefore, led to an evolution of existing networks (GSM – UMTS – LTE) to provide network based localization. Further, in communication networks geo-location information is identified as a useful input that e.g. represents past and current channel state information and conditions (short- and long-term statistics) and network constellations. Current information jointly with mobility information leads to short-term predictions that have an impact on the different communication layers such as PHY, MAC or network management. Challenging applications of today and in the future demand a much more precise accuracy in the cm-range. We will survey the cellular network evolution of localization and outline potential lessons to be learned for future cellular generations, as well as a timely status of cellular localization within the 5G standard.
