Terminal Link Priority Across UL and Sidelink RAT Conflicts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In the 5G NR system, there is no effective solution for determining which link transmission to prioritize when uplink (UL) and side link (SL) transmissions cannot be performed simultaneously, especially in scenarios involving different Radio Access Technologies (RATs) or cell groups.
Innovation Solution
A method and terminal device that determine preferentially performing at least one first transmission based on access types, including Radio Access Technologies (RAT) and cell groups, by comparing and prioritizing transmissions using logic channel attributes and network configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If uplink transmission and side link transmission coexist in 5G NR system, then transmission diversity is improved, but transmission priority determination becomes unclear when conflicts occur
Solution Approach 1:
The patent introduces parameter changes by defining different access types (first access type for uplink transmission, second access type for side link transmission) and assigning priority levels to each. The terminal device determines transmission priority based on these parameter changes, selecting the transmission with higher priority when conflicts occur. This resolves the ambiguity in transmission priority determination while maintaining transmission diversity.
2Adaptability or versatility
If multiple access types coexist in terminal device, then system capability is improved, but resource conflict resolution becomes complex
Solution Approach 1:
The patent applies segmentation by dividing access types into distinct categories (first access type and second access type) with different priority levels. The terminal device separately manages each access type according to its priority, simplifying the resource conflict resolution process. This segmentation approach maintains system capability while reducing the complexity of handling multiple access types.
3Productivity
If transmission priority is determined based on access type, then resource allocation efficiency is improved, but transmission flexibility is reduced
Solution Approach 1:
The patent introduces dynamics by allowing the terminal device to dynamically determine transmission priority based on the actual access type and network configuration. The device can adapt its transmission strategy in real-time, selecting between different access types based on current conditions. This dynamic approach maintains transmission flexibility while improving resource allocation efficiency through priority-based decision making.
