Solution Overview

Problem

Current wireless communication systems face challenges in managing interference between in-vehicle wireless networks of adjacent vehicles, which can disrupt communication and inhibit the functioning of sensors and other vehicle components.

Innovation Solution

A method and apparatus for inter-vehicle wireless in-vehicle network interference management, where user equipment (UE) transmits a wireless in-vehicle network (wIVN) capability indication to alert other UEs of the presence of a wIVN, facilitating proactive mitigation by exchanging configuration information to establish mutually compatible operating parameters, thereby reducing interference.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If wireless communication is used between adjacent vehicles, then communication capability is improved, but interference between in-vehicle networks occurs

Engineering Contradiction:

Improvecommunication capabilityVSAvoidinterference between in-vehicle networks

Core Design Contradiction:

Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The system performs preliminary actions by transmitting wIVN capability indications and negotiating configuration information before actual wireless communication begins. This allows vehicles to establish mutually compatible operating parameters in advance, preventing interference issues from arising during active communication.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system changes operating parameters such as frequency, time, and power levels based on negotiated configuration information. By dynamically adjusting these parameters to achieve compatibility, the system enables wireless communication while minimizing interference between adjacent vehicles' in-vehicle networks.

Inventive Principle:

Principle #35Parameter changes

2Object-affected harmful factors

If interference management protocols are implemented, then interference is reduced, but communication complexity increases

Engineering Contradiction:

Improveinterference levelVSAvoidcommunication protocol complexity

Core Design Contradiction:

Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The system implements self-service by enabling vehicles to autonomously negotiate their own configuration information and determine compatible operating parameters without requiring complex centralized control. Each vehicle independently transmits wIVN capability indications and processes responses to establish interference-free communication.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The system uses feedback mechanisms where vehicles exchange wIVN capability indications and configuration information to continuously monitor and adjust their operating parameters. This feedback loop allows the system to maintain low interference levels while keeping protocol complexity manageable through iterative negotiation.

Inventive Principle:

Principle #23Feedback

AI summary

Various aspects of the present disclosure generally relate to wireless communications. In some aspects, a user equipment (UE) may transmit a wireless in-vehicle network (wIVN) capability indication that indicates that the UE is associated with a vehicle that includes a wIVN; receive a response to the wIVN capability indication from another UE; and provide configuration information to a wIVN control unit of the vehicle associated with configuring the wIVN based at least in part on the response. Numerous other aspects are provided.
