Abstract: In this paper, the channel measurements for 5th generation mobile networks (5G) potential spectrum at 3.35 GHz, 4.9 GHz and 5.4 GHz have been performed in the urban macro cell scenarios in China. The measured cases include line-of-sight (LOS) and non-line-of-sight (NLOS) propagation. After acquiring the channel impulse response from the measurement data, the empirical log-distance path loss models are derived. Free-space and ITU-R models are analysed as references. To explore the relation between path loss and carrier frequency, we revise the proposed path loss models by introducing the frequency dependence coefficient (FDC). Furthermore, when FDC is applied, a more accurate description of path loss differences among three frequencies can be obtained in NLOS case. Measurements can be implemented in more scenarios to acquire optimised channel models in the future.
