5G and PDR Deep Fusion Positioning Technology in Case of Sparse Stations Deployment

5G positioning enables integration with communication networks to share resources. However, the deployment of indoor coverage sites based on communication needs is sparse, resulting in insufficient available positioning signal quantity in some areas. For this issue, 5G and PDR deep fusion positioning methods were proposed and verified in a typical 5G sparse station environment, the technology can complement positioning technology advantages, and meet the demand for high-precision indoor continuous positioning, so expanding the applicable scenarios of 5G positioning under various conditions.
