Solution Overview

Problem

Communication conflicts between sidelink (SL) and uplink (UL) or downlink (DL) channels in terminal devices, such as vehicle user equipment (VUE), affect communication performance, and existing methods fail to effectively manage these conflicts.

Innovation Solution

A wireless communication method where a terminal device determines the channel transmission state based on the priority of data or signaling associated with conflicting channels, prioritizing one channel over the other to avoid conflicts and ensure optimal power allocation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the terminal device transmits on both SL and UL/DL channels simultaneously, then communication coverage is expanded, but communication performance deteriorates due to channel conflicts

Engineering Contradiction:
Improvecommunication coverageVSAvoidcommunication performance
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The patent changes the parameter of transmission power allocation by introducing priority-based power distribution. When channel conflicts are detected, the system adjusts transmission parameters (power levels) based on channel priorities, allowing simultaneous SL and UL/DL transmissions without severe performance degradation. This resolves the contradiction by enabling multi-channel operation while maintaining communication performance through dynamic parameter adjustment.

Inventive Principle:
Principle #35Parameter changes

2Reliability

If the terminal device prioritizes SL transmission, then SL communication reliability is improved, but UL/DL communication performance deteriorates

Engineering Contradiction:
ImproveSL communication reliabilityVSAvoidUL/DL communication performance
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The patent implements dynamic priority-based power allocation where transmission parameters are not fixed but adjust based on real-time channel conditions and priority levels. The system dynamically determines power distribution between SL and UL/DL channels according to their respective priorities, enabling flexible adaptation that maintains both SL reliability and UL/DL performance without rigid prioritization.

Inventive Principle:
Principle #15Dynamics

3Reliability

If the terminal device allocates more power to SL channel, then SL transmission quality is improved, but total power efficiency deteriorates

Engineering Contradiction:
ImproveSL transmission qualityVSAvoidpower efficiency
Core Design Contradiction:
ReliabilityVSLoss of energy

Solution Approach 1:

The patent optimizes power distribution parameters by introducing priority-weighted power allocation. Instead of allocating excessive power to SL channels, the system calculates optimal power levels based on channel priorities and conditions, ensuring SL transmission quality is maintained while minimizing unnecessary power consumption. This resolves the energy efficiency issue by making power allocation proportional to actual communication needs and priority levels.
