Solution Overview
Problem
Existing wireless communication systems face challenges in efficiently prioritizing and managing the transmission of object information sets in vehicle-to-everything (V2X) communication technologies, particularly in scenarios involving multiple detected objects, leading to potential message overflow and inefficiencies.
Innovation Solution
A method and device for obtaining detected object information sets, performing prioritization based on a prioritization mechanism, selecting a subset based on a maximum number of sets, and transmitting the message within a transmission interval, utilizing a processing device with transceivers and processors to manage object information effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If all detected object information sets are transmitted without prioritization, then complete object information is provided, but message overflow occurs and transmission efficiency decreases
Solution Approach 1:
The patent segments the transmission process by dividing object information sets into priority levels (first priority, second priority, etc.). Each priority level is transmitted in separate message batches within a transmission interval, allowing the system to manage large volumes of object data without causing message overflow while ensuring critical information is transmitted first.
Solution Approach 2:
The patent changes the parameter of transmission ordering by introducing priority levels and transmission orders for object information sets. By assigning different transmission priorities to different object sets based on their importance, the system optimizes transmission efficiency while maintaining reliability for critical objects.
2Productivity
If object information sets are prioritized and a subset is selected for transmission, then transmission efficiency improves and message overflow is reduced, but some object information may be omitted
Solution Approach 1:
The patent performs preliminary prioritization and selection of object information sets before transmission. By pre-determining which object sets to transmit based on priority levels and transmission orders, the system efficiently manages message volume while ensuring that the most critical object information is always included in the transmission.
Solution Approach 2:
The patent implements a dynamic transmission strategy where the composition of transmitted object information sets changes based on priority levels and transmission intervals. The system adaptively selects which objects to transmit in each message batch, balancing completeness and efficiency dynamically rather than using a static approach.
3Speed
If multiple object information sets are transmitted in parallel without ordering, then transmission speed is maximized, but message management complexity increases and overflow risk rises
Solution Approach 1:
The patent segments object information sets into ordered priority groups, which simplifies message management by providing a clear transmission sequence. This segmentation approach reduces the complexity of managing multiple simultaneous transmissions while maintaining high transmission speeds through efficient parallel processing of segmented data.
Solution Approach 2:
The patent introduces transmission order as a new parameter to manage parallel transmissions. By assigning specific transmission orders to different object information sets, the system maintains speed through parallel processing while reducing management complexity through structured parameter-based organization.
