5G mmWave communication systems have the potential to jointly estimate the positions of user equipment (UE) and mapping their propagation environments using a single base station. But such potential depends on the characteristics of the reflecting surfaces, such as a deterministic specular nature, a stochastic diffuse/scattering nature, or a combination of both. In this letter, we proposed a 5G positioning and mapping algorithm with unknown orientation and clock bias for single-bounce diffuse multipath channel models. The method is able to accurately localize, calibrate and synchronize the UE, even in the absence of line-of-sight and specular components. This enables robust positioning and mapping using only diffuse multipath.

漫射多路径的 5G 同步、定位和映射


5G 毫米波通信系统有潜力联合估计用户设备 (UE) 的位置并使用单个基站映射其传播环境。但这种潜力取决于反射表面的特性，例如确定性镜面反射性质、随机漫射/散射性质或两者的组合。在这封信中，我们提出了一种针对单跳扩散多径信道模型的具有未知方向和时钟偏差的 5G 定位和映射算法。即使在没有视线和镜面反射分量的情况下，该方法也能够准确地定位、校准和同步 UE。这使得仅使用扩散多路径即可实现稳健的定位和映射。
