TECHNIQUES FOR SIDELINK SENSING AND POSITIONING - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240163875 titled 'TECHNIQUES FOR SIDELINK SENSING AND POSITIONING

Simplified Explanation

The disclosure provides systems, methods, and apparatus for measurement and reporting procedures associated with a sidelink positioning reference signal (SL-PRS). In one aspect, a first User Equipment (UE) may transmit an SL-PRS to a second UE using a dedicated slot format or structure. The second UE can then use the SL-PRS to acquire positioning information through different methods such as OTDOA-based or RTT-based positioning.

• First UE functions as a sidelink anchor node transmitting SL-PRS to a second UE.
• Dedicated slot format or structure used for SL-PRS transmissions.
• Resources selected for transmission via sensing and exclusion or using dedicated resources.
• Second UE receives SL-PRS for positioning information acquisition.
• Second UE may transmit a second SL-PRS to facilitate positioning information acquisition at the first UE.

Potential Applications

The technology can be applied in various industries such as telecommunications, autonomous vehicles, asset tracking, and emergency services for accurate positioning and location-based services.

Problems Solved

- Improved accuracy in positioning information acquisition. - Efficient utilization of dedicated resources for SL-PRS transmissions.

Benefits

- Enhanced reliability and precision in location-based services. - Facilitates seamless communication between UEs for positioning information exchange.

Potential Commercial Applications

"Enhancing Location-Based Services with Sidelink Positioning Reference Signal Technology"

Possible Prior Art

Prior art may include existing methods for positioning information acquisition using different signals and protocols in wireless communication systems.

How does this technology impact battery life in User Equipment devices?

The article does not address the potential impact of SL-PRS transmissions on the battery life of User Equipment devices. This aspect is crucial as increased transmissions may drain the battery faster, affecting the overall user experience and device usability.

What are the potential security implications of using SL-PRS for positioning information exchange?

The article does not delve into the security aspects of utilizing SL-PRS for positioning information exchange between User Equipment devices. Understanding the security vulnerabilities and implementing robust encryption measures is essential to safeguard sensitive location data from unauthorized access or manipulation.

Original Abstract Submitted

this disclosure provides systems, methods and apparatus, for measurement and reporting procedures associated with a sidelink positioning reference signal (sl-prs). in one aspect, a first user equipment (ue), which may function as a sidelink anchor node, may transmit an sl-prs to a second ue in accordance with a slot format or structure that is dedicated for sl-prs transmissions. the first ue may select resources for the transmission of the sl-prs via sensing and exclusion or using a set of resources that are dedicated for sl-prs transmissions. the second ue may receive the sl-prs and use the sl-prs to acquire positioning information, in accordance with an observed time difference of arrival (otdoa)-based positioning method, or may transmit a second sl-prs to the first ue to facilitate acquisition of positioning information at the first ue, in accordance with a round-trip-time (rtt)-based positioning method.
