Abstract: In this paper, the mobile channel propagation measurements at 3.5 GHz and 6 GHz have been performed in urban micro-cell scenario in the city of China. The measured cases include line-of-sight (LOS) and non-line-of-sight (NLOS) propagation. Statistical results and comparative analysis are presented in this paper, including power delay profiles (PDPs),path loss (PL), coverage, and root mean square (rms) delay spread (DS). It can be found that PDPs measured from campaign keep similarity in these two bands. The result based on PDPs demonstrates that, in mobile condition, the PL exponent of 6 GHz is a little greater than that of 3.5 GHz in both LOS and NLOS propagation. Moreover, as the frequency increases, the path loss will increase and the coverage will remarkably degrade. Last, the rms DS of 3.5 GHz and 6 GHz are similar in LOS case, while that of 3.5 GHz is higher in NLOS case.
