Abstract
Millimeter-wave communication is considered one of the key enablers for 5G systems as it contributes to achieving high data rate with very wideband transmission, high beam forming gain and massive MIMO techniques. However, the wireless link in the extremely high frequency band (mm W band) is characterized by quasi-optical behaviour, i.e., line-of sight dominant and a few reflected (single bounce) paths. Leveraging this property along with the capability of beam forming and large signal bandwidth to radio-based positioning, accurate and reliable location-awareness can be achieved all time via mobile network. More specifically, a new approach for localization can be developed to (i) determine user's position from a single access point, and (ii) determine the orientation of the user, with respect to the access point. In this talk, we will illustrate all the benefits of this new localization solution, a brief introduction to the underpinning mathematical model and the trade-off with communications. Focus is on the analysis of the system model, achievable localization performance and dependency with system design parameters such as number of antennas, OFDM signal formation and interoperability with GNSS. The talk is centered around the application of autonomous driving use-case tackled in the EU H2020 5GCAR project.
