A Geometry-Based Stochastic Channel Model for UAV-to-Ground Integrated Sensing and Communication Scenarios

Xiaobo Yang;Daosen Zhai;Ruonan Zhang;Lei Liu;Jun Du;Victor C. M. Leung

IEEE Transactions on Vehicular Technology

Year: 2024 | Early Access Article |

Integrated sensing and communication (ISAC) is one of the key technologies in the sixth generation wireless communication network (6G). The wireless channel modeling for 6G should not only consider the communication channel, but also include the sensing channel. In this paper, we propose an air-to-ground (A2G) channel model for ISAC based on an unmanned aerial vehicle (UAV). We first calculate the...Show More

Air-to-ground (A2G) communication based on Unmanned aerial vehicle (UAV) is an important part of the future communication system. In this paper, an A2G channel model with UAV three-dimensional (3D) wobbles (pitch, roll, and yaw) based on the geometry-based stochastic model (GBSM) is proposed. On this basis, the UAV’s internal vibration is modeled as a sinusoidal random process, and the UAV wobble ...Show More

In air-to-ground unmanned aerial vehicle (UAV) communications, an accurate channel propagation model is very important for the evaluation and design of communication systems. For this purpose, we have conducted several channel measurement campaigns in the airport area at UHF- and L-band (around 433 MHz and 1.518 GHz). In the line-of-sight (LoS) case, we give the distance-dependent pathloss models ...Show More
