  Due to the large bandwidth available, millimeter-Wave (mmWave) bands are
considered a viable opportunity to significantly increase the data rate in
cellular and wireless networks. Nevertheless, the need for beamforming and
directional communication between the transmitter and the receiver increases
the complexity of the channel estimation and link establishment phase.
Location-aided beamforming approaches have the potential to enable fast link
establishment in mmWave networks. However, these are often very sensitive to
location errors. In this work, we propose a beamforming algorithm based on
tracking spatial correlation of the available strong paths between the
transmitter and the receiver. We show that our method is robust to uncertainty
in location information, i.e., location error and can provide a reliable
connection to a moving user along a trajectory. The numerical results show that
our approach outperforms benchmarks on various levels of error in the location
information accuracy. The gain is more prominent in high location error
scenarios.
