Problem statement

Cellular networks have evolved towards more and more accurate geo-located services. On the one hand, User Equipment (UE) can now be localized based on their communications with the cellular Base Stations (BS). On the other hand, the processing is moving more and more towards the edge of the cellular network. What is more, the processing is required to be distributed, i.e., all BS can compute the US’s position and trajectory. To do so, many network characteristics should be studied such as: geometrical and logical topology, speed of convergence, estimation accuracy, etc.

Given massive MIMO introduced in 5G, BSs could be installed in small and compact places like lampposts. This advantage introduces new constraints and possibilities in terms of geometric configuration of the network, such as streets lights, roundabouts, squares, etc.
