Solution Overview

Problem

Existing uplink/SideLink (SL) transmission conflict resolution methods in V2X scenarios fail to distinguish between uplink transmissions with different Quality of Service (QoS) attributes, leading to unreasonable utilization of transmission resources.

Innovation Solution

A method that prioritizes one transmission over another based on the QoS attributes associated with both transmissions, using specific priority thresholds and conditions to determine the prioritization.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If only the QoS attributes of SL are considered in uplink/SL transmission conflict resolution, then the SL transmission priority can be determined, but the uplink transmissions with different QoS attributes cannot be distinguished leading to unreasonable utilization of transmission resources

Engineering Contradiction:
Improvetransmission priority determinationVSAvoidtransmission resource utilization
Core Design Contradiction:
Adaptability or versatilityVSProductivity

Solution Approach 1:

The patent segments the transmission conflict resolution by introducing multiple priority levels (first priority for uplink, second priority for SL) and multiple thresholds (first threshold, second threshold) to differentiate between various transmission types and their QoS attributes, enabling fine-grained control over transmission prioritization

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent changes the parameter of priority comparison by introducing threshold-based priority levels. Instead of direct priority comparison, it uses threshold comparisons (first priority vs. first threshold, second priority vs. second threshold) to determine transmission priority, allowing flexible adaptation to different QoS requirements

Inventive Principle:
Principle #35Parameter changes

2Ease of operation

If the priority comparison method is simplified to only consider SL QoS attributes, then the conflict resolution process is simpler, but it leads to unreasonable utilization of transmission resources by not distinguishing uplink transmissions with different QoS attributes

Engineering Contradiction:
Improveconflict resolution processVSAvoidtransmission resource utilization
Core Design Contradiction:
Ease of operationVSProductivity

Solution Approach 1:

The patent segments the priority comparison process into distinct steps: comparing first priority against first threshold, comparing second priority against second threshold, and then determining final transmission priority based on these comparisons. This segmented approach maintains operational simplicity while enabling sophisticated resource differentiation

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent applies different priority thresholds and comparison criteria to different transmission types (uplink vs. SL). By assigning local quality parameters (first threshold for uplink, second threshold for SL), it enables tailored priority determination for each transmission type while maintaining an overall simple conflict resolution framework

Inventive Principle:
Principle #3Local quality

AI summary

The disclosure discloses a method for resolving a transmission conflict and relates to the field of wireless communication. The method comprises: when two transmissions experience a conflict, prioritizing the transmission of one transmission among the two transmissions according to quality of service (QoS) attributes respectively associated with the two transmissions. When two transmissions experience a conflict, the QoS attributes of the two transmissions are considered, and the priority of transmission is determined according to the QoS attributes respectively associated with the two transmissions to thereby determine an object that is prioritized for transmission, which may effectively allocate network bandwidth and use network resources more reasonably.
