==SUPPLEMENTAL POSITIONING REFERENCE SIGNAL TRANSMISSION - A simplified explanation of the abstract==


This abstract first appeared for US patent application 17389855 titled 'SUPPLEMENTAL POSITIONING REFERENCE SIGNAL TRANSMISSION

==Simplified Explanation==

Methods, systems, and devices for wireless communications are described in this patent application. The innovation involves a first user equipment (UE) transmitting positioning reference signals (PRSs) to a second UE in an unshared radio frequency spectrum and transmitting supplemental PRSs to the second UE in a shared spectrum. The second UE then uses both the PRSs in the unshared spectrum and the supplemental PRSs to compute a position of the first UE, resulting in improved accuracy.

* The first UE transmits PRSs to the second UE in an unshared radio frequency spectrum.
* The first UE also transmits supplemental PRSs to the second UE in a shared spectrum.
* The second UE uses both the PRSs in the unshared spectrum and the supplemental PRSs to compute the position of the first UE.
* The configuration for the supplemental PRSs can be signaled by either the first UE or a base station.

== Potential Applications ==
This technology can have various applications in the field of wireless communications, including:

* Location-based services: Improved accuracy in computing the position of a UE can enhance location-based services such as navigation, asset tracking, and emergency services.
* Network optimization: The ability to accurately determine the position of UEs can aid in optimizing network resources and improving overall network performance.
* Internet of Things (IoT): IoT devices can benefit from accurate positioning information for applications like smart cities, agriculture, and industrial automation.

== Problems Solved ==
The technology addresses the following problems in wireless communications:

* Limited accuracy: Traditional methods of computing UE positions may have limited accuracy due to various factors such as signal interference and multipath propagation. This technology improves the accuracy of position computation by utilizing both unshared and shared spectrum PRSs.
* Spectrum efficiency: By transmitting supplemental PRSs in a shared spectrum, the technology optimizes the use of available spectrum resources, increasing efficiency in wireless communications.

== Benefits ==
The use of this technology offers several benefits:

* Improved accuracy: By combining PRSs from both unshared and shared spectrum, the computed position of a UE can be more accurate, leading to better performance of location-based services and other applications.
* Enhanced spectrum utilization: Transmitting supplemental PRSs in a shared spectrum allows for efficient use of available spectrum resources, maximizing the capacity of wireless networks.
* Flexibility in configuration: The configuration for the supplemental PRSs can be signaled by either the UE or a base station, providing flexibility in adapting to different network scenarios and requirements.


==Original Abstract Submitted==

Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may be configured to transmit positioning reference signals (PRSs) to a second UE in an unshared radio frequency spectrum and transmit supplemental PRSs to the second UE in a shared spectrum. The second UE may then use the supplemental PRSs in addition to the PRSs in the unshared spectrum to compute a position of the first UE. In some cases, the first UE may signal a configuration for the supplemental PRSs to the second UE, and, in other cases, a base station may signal the configuration for the supplemental PRSs to the second UE. In any case, because the second UE may use both the PRSs in the unshared spectrum and the supplemental PRSs to compute the position of the first UE, the accuracy of the computed position of the first UE may be improved.
