6G Wireless Channel Scenario Extensions and Characteristics Analysis for Urban Environment

Urban wireless communications are one of most important scenarios in the sixth generation (6G) global communication networks. To provide customized high-quality services for all users in various 6G urban wireless communication scenarios, it is necessary and fundamental to study all kinds of 6G urban wireless channel scenarios and establish corresponding channel models for each scenario. However, existing standardized channel models are insufficient to cover all 6G urban communication scenarios. This paper aims to extend the conventional urban communication scenarios with detailed definitions and environmental parameters to accurately establish corresponding channel models. Specifically, the statistical properties of high speed train (HST) scenario are simulated and compared with those of measurement data. The channel model simulation results match well with the channel measurement data, which demonstrates the correctness of the channel model. Then, by applying the proposed precise scenarios and the corresponding model parameters to the channel model, corresponding channel characteristics can be quickly provided. Finally, the channel characteristics of several urban scenarios are simulated and analyzed.
