PEDESTRIAN POSITIONING VIA VEHICLE COLLABORATION - A simplified explanation of the abstract
This abstract first appeared for US patent application 18420475 titled 'PEDESTRIAN POSITIONING VIA VEHICLE COLLABORATION
Simplified Explanation
The patent application describes techniques for using ranging signals to determine the position of a pedestrian user equipment (P-UE) in a wireless communication network.
- A UE receives ranging signals from other UEs, measures properties of these signals, and calculates the P-UE's position based on these properties.
- The P-UE transmits ranging signals, receives estimated positions and confidences from vehicle UEs, and calculates its position based on this information.
Potential Applications
This technology could be applied in:
- Indoor navigation systems
- Location-based services for pedestrians
Problems Solved
This technology addresses the following issues:
- Accurate positioning of pedestrians in urban environments
- Enhancing safety features in smart cities
Benefits
The benefits of this technology include:
- Improved accuracy in determining pedestrian locations
- Enhanced communication between pedestrians and vehicles
Potential Commercial Applications
This technology could be commercially used in:
- Smart city infrastructure development
- Location-based advertising services
Possible Prior Art
One possible prior art for this technology could be GPS-based pedestrian tracking systems used in urban environments.
Unanswered Questions
1. How does this technology handle signal interference in crowded urban areas? 2. What are the limitations of this technology in terms of indoor positioning accuracy?
Original Abstract Submitted
Disclosed are techniques for using ranging signals to determine a position of a pedestrian user equipment (P-UE). In an aspect, a UE receives a plurality of ranging signals transmitted by one or more UEs, measures one or more properties of each of the plurality of ranging signals, and calculates an estimate of the position of the P-UE based on the one or more properties of each of the plurality of ranging signals. In an aspect, the P-UE transmits a plurality of ranging signals, receives a first message and a second message from first and second vehicle UEs (V-UEs), the first and second messages including first and second estimated positions of the P-UE and associated first and second confidences, and calculates an estimate of the position of the P-UE based on the first estimated position, the first confidence, the second estimated position, the second confidence, or a combination thereof.
