VIRTUAL ANCHOR DETECTION BASED ON CHANNEL TAP REMOVAL - A simplified explanation of the abstract

This abstract first appeared for US patent application 17938165 titled 'VIRTUAL ANCHOR DETECTION BASED ON CHANNEL TAP REMOVAL

Simplified Explanation

The patent application describes techniques for identifying virtual anchors based on data samples associated with a user equipment (UE) and multipath components (MPCs) obtained by the UE. The network entity determines if any non-line-of-sight (NLOS) MPCs are associated with previously identified virtual anchors and updates the database of virtual anchors accordingly.

• Identification of virtual anchors based on data samples and MPCs
• Removal of NLOS MPCs associated with virtual anchors from data samples
• Addition of new NLOS MPCs to the database of virtual anchors
• Updating the database of virtual anchors based on MPC associations

Potential Applications

This technology could be applied in:

• Indoor positioning systems
• Asset tracking
• Location-based services

Problems Solved

This technology helps in:

• Improving accuracy of location tracking
• Enhancing reliability of indoor positioning systems

Benefits

The benefits of this technology include:

• Better user experience in location-based services
• Increased efficiency in asset tracking

Potential Commercial Applications

This technology could be commercially applied in:

• Smart buildings
• Logistics and supply chain management

Possible Prior Art

One possible prior art could be:

• Indoor positioning systems using Wi-Fi signals

Unanswered Questions

How does this technology handle dynamic environments where virtual anchors may change frequently?

The technology does not address how it adapts to changing virtual anchors in dynamic environments.

What is the computational overhead of constantly updating the database of virtual anchors?

The patent application does not provide information on the computational resources required for updating the database of virtual anchors.

Original Abstract Submitted

Disclosed are techniques for identifying virtual anchors. In an aspect, a network entity obtains a set of data samples associated with a user equipment (UE), each data sample comprising a location of the UE and a set of multipath components (MPCs) obtained by the UE, and determines whether any MPCs in a subset of non-line-of-sight (NLOS) MPCs selected from at least one set of MPCs are associated with any previously identified virtual anchors in a database of found virtual anchors, wherein one or more first NLOS MPCs are removed from the set of data samples based on the one or more first NLOS MPCs being associated with a previously identified virtual anchor, and wherein one or more second NLOS MPCs are added to the database of found virtual anchors based on the one or more second NLOS MPCs not being associated with any previously identified virtual anchor.
