Solution Overview

Problem

Existing wireless communication systems fail to distinguish between driver and passenger UEs in vehicles, leading to unnecessary activation of the do-not-disturb feature on passenger UEs during vehicle movement, which can degrade their user experience.

Innovation Solution

Implementing ultra-wideband (UWB) ranging to determine the location of UEs within a vehicle, enabling the do-not-disturb feature only for UEs in the driver area by transmitting a DND indication to the driver's UE.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the do-not-disturb feature is activated for all UEs in the vehicle, then driver safety is improved, but passenger user experience deteriorates

Engineering Contradiction:
Improvedriver safetyVSAvoidpassenger user experience
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent segments the vehicle interior into distinct driver area and passenger area using UWB ranging to determine UE locations. The system then applies different DND policies to different segments: DND is activated for UEs detected in the driver area while remaining inactive for UEs in the passenger area, thus resolving the contradiction between driver safety and passenger user experience

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent implements local quality by applying differentiated DND feature behavior based on the spatial location of each UE within the vehicle. The system determines whether a UE is in the driver area or passenger area using UWB ranging and applies the DND feature selectively - activating it locally for driver UEs while maintaining it inactive for passenger UEs, thereby addressing the specific needs of each location

Inventive Principle:
Principle #3Local quality

2Ease of operation

If UWB ranging is implemented to distinguish driver and passenger UEs, then passenger user experience is improved, but device complexity increases

Engineering Contradiction:
Improvepassenger user experienceVSAvoidsystem complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent leverages the multi-functionality of UWB technology, which is already available in modern vehicles for purposes such as keyless entry, interior access control, and driver monitoring. By utilizing this existing universal component for additional UE location tracking and DND feature differentiation, the system avoids adding separate dedicated hardware, thereby limiting the increase in device complexity

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first wireless device may transmit a first ultra-wideband (UWB) ranging signal. The first wireless device may receive a first UWB response from a second wireless device. The first wireless device may transmit an indication to enable do-not-disturb on the second wireless device based at least in part on a first determination, from the first UWB response, that the second wireless device is in a driver area of a vehicle. Numerous other aspects are described.
