UWB Authentication Coordination Using BLE Status Signaling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Concurrent repetitive authentication procedures in wireless communication devices using ultra-wide band (UWB) connections lead to increased power consumption and inefficient use of communication resources.
Innovation Solution
Implementing control signaling to indicate the status of communication between devices, allowing one device to refrain from or perform authentication procedures based on the status of another device, using a different radio access technology (RAT) such as Bluetooth, thereby optimizing power usage and resource efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If concurrent repetitive authentication procedures are performed using UWB connections, then communication reliability is improved, but power consumption increases
Solution Approach 1:
The patent combines the authentication status information from the first device with the existing Bluetooth Low Energy (BLE) advertising data. By merging this additional information into the BLE advertising packets, the system enables collocated devices to share authentication status without requiring separate UWB communication channels, thus reducing redundant authentication attempts while maintaining reliability.
Solution Approach 2:
The patent introduces BLE advertising data as an intermediary medium to transmit authentication status information between collocated devices. Instead of directly performing concurrent UWB authentication procedures, devices use BLE advertising data containing authentication status indicators as an intermediary to coordinate and avoid redundant authentication attempts, thereby reducing power consumption.
2Reliability
If concurrent repetitive authentication procedures are performed using UWB connections, then communication reliability is improved, but communication resource efficiency deteriorates
Solution Approach 1:
The patent merges authentication status information into the existing BLE advertising data structure. This allows multiple devices to share authentication status information through a single communication channel (BLE advertising), eliminating the need for separate UWB authentication coordination messages and improving resource efficiency.
Solution Approach 2:
The system enables devices to autonomously determine authentication status by reading the authentication status indicator from BLE advertising data transmitted by collocated devices. This self-service mechanism eliminates the need for complex inter-device coordination protocols and reduces overhead, thereby improving communication resource efficiency.
3Loss of information
If authentication status information is transmitted via separate channels, then information completeness is improved, but device complexity increases
Solution Approach 1:
The patent combines authentication status information with BLE advertising data into a single integrated communication stream. This merging approach ensures information completeness by including authentication status indicators within the existing advertising packets, while avoiding the complexity of managing separate communication channels for status information.
Solution Approach 2:
The patent makes the BLE advertising data serve multiple functions: it continues to carry standard BLE advertising information while simultaneously transmitting authentication status indicators. This multi-functionality approach maintains information completeness without requiring additional dedicated communication channels, thereby reducing device complexity.

AI summary
This disclosure provides methods, components, devices and systems for power saving in ultra-wide band (UWB) enabled connected devices. Some aspects more specifically relate to an authentication procedure at collocated devices. In some examples, a first wireless device may communicate via a first radio access technology (RAT) with a second device that is collocated with the first wireless device. The first wireless device may be capable of communicating with a third wireless device via a second RAT. The first wireless device may transmit, via the first RAT, a message to the second device that is indicative of a first status of communications between the first wireless device and the third wireless device via the second RAT. In some examples, the second wireless device may change a second status of communications between the second wireless device and the third wireless device based on reception of the message.
