METHOD AND APPARATUS FOR POSITION ESTIMATION USING MOBILE ANCHOR - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240377497 titled 'METHOD AND APPARATUS FOR POSITION ESTIMATION USING MOBILE ANCHOR
The abstract describes a method for determining the position of a target user equipment (UE) using reference signal time difference (RSTD) measurements generated by the UE at different times. These measurements are based on positioning reference signals (PRS) transmitted by stationary and moving anchor entities. The position estimate of the target UE is calculated using the RSTD measurements and anchor-to-anchor receive-transmit (RXTX) time difference measurements.
- The method uses at least three RSTD measurements generated by the target UE at different times.
- Each RSTD measurement is based on PRS transmitted by stationary and moving anchor entities.
- At least two anchor-to-anchor RXTX time difference measurements are generated, associated with the RSTD measurements.
- The position estimate of the target UE is determined based on the set of RSTD measurements and anchor-to-anchor RXTX time difference measurements.
Potential Applications: - Location-based services - Asset tracking - Indoor navigation systems
Problems Solved: - Accurate positioning of target UEs - Improved tracking of mobile devices - Enhanced location-based services
Benefits: - Precise location determination - Efficient asset management - Enhanced user experience in navigation applications
Commercial Applications: Title: Enhanced Location Tracking Technology for Asset Management This technology can be used in industries such as logistics, transportation, and healthcare for efficient asset tracking and management. It can also be integrated into navigation applications for improved user experience.
Questions about the technology: 1. How does this technology improve location accuracy compared to existing methods? This technology utilizes multiple RSTD measurements and anchor-to-anchor RXTX time difference measurements to enhance location accuracy. 2. What are the potential challenges in implementing this technology on a large scale? Implementing this technology on a large scale may require infrastructure upgrades and coordination between anchor entities for seamless operation.
Original Abstract Submitted
the position of a target user equipment (ue) is determined using a set of reference signal time difference (rstd) measurements that includes at least three rstd measurements generated at different times by the target ue. each rstd measurement is produced based on positioning reference signals (prs) transmitted by a stationary anchor entity and corresponding prs transmitted by a moving mobile anchor entity. at least two anchor-to-anchor receive-transmit (rxtx) time difference measurements are generated by an anchor entity, wherein each anchor-to-anchor rxtx time difference measurement is associated with the rstd measurements, and there are fewer anchor-to-anchor rxtx time difference measurements than rstd measurements. the position estimate of the target ue is determined based on the set of rstd measurements and the at least two anchor-to-anchor rxtx time difference measurements.
