Abstract:

5G cellular networks can utilize millimeter wave signals, and support large bandwidths and large antenna arrays, which provide more geometric-based signals and higher delay and angle resolutions. These merits bring new opportunities in positioning the user with limited infrastructure through the use of combined angle and delay information. However, there are many practical challenges to overcome, in order to have a functioning single base station 5G mmWave positioning system. In this paper, we describe a deployed single base station mmWave positioning system, and provide an example of the measurement data. Furthermore, we perform measurement validation on a limited measurement data set by performing base station localization. Additional evaluations performed on simulation model data provide guidelines on the required size of the data set and receiver antenna configuration, which will be implemented in upcoming measurements.

I. Introduction

Absolute and relative positioning of vehicles is required to support a variety of autonomous drive (AD) and advanced driver assistance system (ADAS) services. While accurate relative positioning is enabled with sensors such as radar, camera, lidar [1], and inertial measurement unit (IMU), absolute positioning relies on an external reference. Such a reference can be in the form of a global map (so that local features can be associated in the global map), or in the form of satellites in a global navigation satellite system (GNSS) [2]. When maps are erroneous or out-of-date [3] or insufficiently many satellites are in view, global positioning is compromised [4], leading to safety risks or driver comfort degradation. Hence, alternative absolute positioning sensors, complementing high-resolution maps and GNSS are of high importance.
