Enhanced satellite positioning methods using ultrawideband D2D-based localization for ultra-dense 5G wireless setting

Abstract

The drawbacks of legacy satellite positioning systems necessitate new procedures for high resolution location services. Moreover, location-aware devices, systems and networks are critical for 5G/future network setting that seeks to seamlessly connect global devices in an all-IP network. It is therefore believed that satellite positioning could be enhanced with impulse radio (IR) ultrawideband (UWB) localization approaches for accuracy-critical situations expected in 5G wireless. This paper presents results of research on enhanced satellite positioning methods for ultra-dense 5G setting. The methods combine information from satellites, fixed wireless networks, wireless LANs and cellular communication along with global cloud databases. This is conceptualized as an IR-UWB device-to-device (D2D) overlay network that seamlessly incorporates satellite data into the 5G terrestrial network environment. A link to at least one satellite on the global positioning constellation would suffice for accurate localization. Also presented is the IR UWB D2D-propagation-based combined localization and communication scheme (UD-CLOCS). The UD-CLOCS scheme transmits location and communication data in a single signal while performance evaluations have been impressive. It is believed that the solutions have potential for robust and cost-efficient satellite positioning as well as prospect to de-congest licensed spectrum in 5G wireless setting. The significance of the research outcomes is that satellite positioning signal and data could be seamlessly integrated into global 5G networks for enhanced positioning services as well as improved spectral efficiency.
