Co-Location Identifier for Wireless Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems lack an effective means to determine when multiple devices are co-located, leading to erroneous operations and network congestion due to unnecessary location traffic and resource wastage in dense deployments.
Innovation Solution
The implementation of a device location identifier (DLID) within communication frames allows wireless devices to identify co-located devices, thereby avoiding unnecessary ranging and location protocols, reducing network congestion, and optimizing spectrum use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If wireless devices perform ranging and location protocols with multiple devices, then location information can be obtained, but network congestion and resource wastage occur due to unnecessary protocols in dense deployments
Solution Approach 1:
The patent applies preliminary action by including a device location identifier (DLID) in beacon frames and probe response frames before actual ranging protocols are executed. This allows devices to pre-determine co-location status and avoid unnecessary ranging protocols, thus maintaining location accuracy while preventing network congestion.
Solution Approach 2:
The patent extracts the location identification function from the full ranging protocol sequence by implementing a separate DLID mechanism. This extracted identifier allows devices to quickly determine co-location status without executing complete ranging protocols, reducing network overhead while preserving necessary location information.
2Ease of operation
If devices assume separate locations and perform location protocols, then location determination can proceed, but erroneous operations occur when devices are actually co-located
Solution Approach 1:
The patent implements feedback by having receiving devices compare DLID values from different transmitting devices and provide implicit feedback about co-location status. When DLID values match, the receiving device identifies co-location and adjusts its operations accordingly, ensuring reliable operation without erroneous assumptions about separate locations.
Solution Approach 2:
The patent performs preliminary location identification by exchanging DLID information before executing location protocols. This preliminary action allows devices to verify whether transmitting devices are co-located, preventing erroneous operations while maintaining ease of protocol execution when devices are properly separated.
3Quantity of substance
If multiple devices share the same physical location, then resource consolidation is possible, but device location identification becomes ambiguous without co-location detection
Solution Approach 1:
The patent merges the location identification function into the existing beacon and probe response frame structures by incorporating DLID fields. This combining approach allows multiple devices at the same physical location to be identified through a shared identifier, simplifying location identification while accommodating high device density without increasing overall system complexity.
Solution Approach 2:
The patent introduces DLID as an intermediary element that mediates between multiple co-located devices and the location identification process. This intermediary identifier allows devices to be distinguished or grouped based on physical location without requiring complex identification mechanisms, thus managing device density while maintaining identification simplicity.

AI summary
A wireless communication device (WDEV) includes a communication interface and a processor, among other possible circuitries, components, elements, etc. to support communications with other WDEV (s) and to generate and process signals associated with such communications. The WDEV supports first communications with a first other WDEV and supports second communications with a second other WDEV. The WDEV processes the first communications and the second communications to determine whether the first other WDEV and the second other WDEV are substantially co-located at a physical location. When not co-located, the WDEV processes the first communications and the second communications based on at least one of a ranging or a location protocol to determine location information of the WDEV. Alternatively, when co-located, the WDEV stores information that indicates co-location of the first other WDEV and the second other WDEV.
