Solution Overview

Problem

Existing wireless communication systems face challenges in efficiently managing duplicate transmissions of information messages, particularly in scenarios where multiple connected devices detect an unconnected road user, leading to resource wastage and potential safety gaps in traffic information sharing.

Innovation Solution

The proposed method involves a device detecting an object, obtaining a transmission persistence level (TPL) value, and exchanging TPL values with other devices to determine the priority for transmitting information about the object, thereby preventing duplicate transmissions and optimizing resource use.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If multiple connected devices transmit information about the same unconnected road user, then information sharing coverage is improved, but duplicate transmissions occur causing resource wastage

Engineering Contradiction:

Improveinformation sharing coverageVSAvoidwireless communication resources

Core Design Contradiction:

ReliabilityVSLoss of energy

Solution Approach 1:

The system performs preliminary actions by having devices exchange TPL values before actual transmission occurs. Each device calculates and shares its transmission persistence level with neighboring devices, allowing them to pre-determine who should transmit and avoid duplicate transmissions before they happen.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system implements feedback mechanisms where devices receive TPL values from other devices and use this feedback information to make transmission decisions. The receiving device compares its own TPL with the received TPL and adjusts its transmission behavior accordingly, creating a closed-loop control system that prevents duplicates.

Inventive Principle:

Principle #23Feedback

2Manufacturing precision

If devices continuously monitor and exchange TPL values, then transmission priority determination is improved, but system complexity increases

Engineering Contradiction:

Improvetransmission priority determinationVSAvoidmessage exchange protocol

Core Design Contradiction:

Manufacturing precisionVSDevice complexity

Solution Approach 1:

The system changes the parameter space by introducing TPL values as a new dimension for decision-making. Instead of using complex multi-criteria evaluation, the system reduces the transmission priority determination to a comparison of TPL parameter values, simplifying the decision logic while maintaining precision.

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The system applies local quality by having each device independently calculate its own TPL based on local conditions (distance to object, detection persistence) rather than requiring centralized coordination. This distributes the complexity calculation locally to each device, reducing overall system complexity.

Inventive Principle:

Principle #3Local quality

AI summary

Provided are a method for performing wireless communication by a first device, and an apparatus for supporting same. The method may comprise: detecting an object; obtaining a first transmission persistence level (TPL) value related to the object; receiving, from a second device, a first message including a second TPL value related to the object; and determining whether to transmit a second message including information related to the object, based on the first TPL value and the second TPL value.
