Abstract—5G new radio (NR) provides new opportunities for

accurate positioning from a single reference station: large bandwidth

combined with multiple antennas, at both the base station

and user sides, allows for unparalleled angle and delay resolution.

Nevertheless, positioning quality is affected by multipath and

clock biases. We study, in terms of performance bounds and

algorithms, the ability to localize a vehicle in the presence of

multipath and unknown user clock bias. We find that when

a sufficient number of paths is present, a vehicle can still be

localized thanks to redundancy in the geometric constraints.

Moreover, the 5G NR signals enable a vehicle to build up a

map of the environment.
