Solution Overview
Problem
Current wireless communication systems, particularly in 5G NR, face challenges in efficiently prioritizing sidelink and uplink transmission signals, leading to potential bottlenecks and reduced performance in multi-access technologies.
Innovation Solution
A method and apparatus are provided to compare the priorities of uplink and sidelink transmission signals at a user equipment (UE) and base station, allowing for dynamic scheduling based on signal priorities to optimize transmission and reception.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the system transmits both uplink and sidelink signals simultaneously, then communication versatility is improved, but resource allocation efficiency deteriorates due to priority conflicts
Solution Approach 1:
The patent applies parameter changes by dynamically adjusting the priority levels of uplink and sidelink signals based on predefined criteria. The base station configures priority parameters for different signal types, and the UE adjusts transmission priorities by comparing these parameters. This allows the system to maintain versatility in handling multiple signal types while improving resource allocation efficiency through structured priority management.
2Reliability
If the system prioritizes high-priority signals, then transmission reliability is improved, but system complexity increases due to prioritization procedures
Solution Approach 1:
The patent applies preliminary action by pre-configuring priority levels for different signal types at the base station before actual transmission occurs. The base station provides priority configurations to the UE in advance, enabling the UE to automatically make prioritization decisions without complex real-time processing. This ensures reliable transmission of high-priority signals while keeping system complexity manageable through pre-established rules.
3Manufacturing precision
If the base station provides detailed scheduling for all signals, then transmission precision is improved, but signaling overhead increases
Solution Approach 1:
The patent applies segmentation by dividing the scheduling control into two parts: the base station provides overall priority configurations and resource allocations for different signal types, while the UE autonomously determines the final transmission timing and resource selection based on these configurations. This segmented approach provides sufficient transmission precision for priority-based signals while significantly reducing signaling overhead compared to detailed base station control of every transmission.

AI summary
A method and apparatus for prioritization of sidelink and uplink. The apparatus compares priorities of a first group of transmission signals to determine a first signal from the first group of transmission signals having a highest priority. The first group of transmission signals comprise at least one uplink signal and at least one sidelink transmission signal. The apparatus compares a priority of the first signal from the first group of transmission signals against a reception signal having a highest priority of a second group of reception signals to determine to transmit at least the first signal from the first group of transmission signals or to receive at least one reception signal from the second group of reception signals. The second group of reception signals comprises at least one sidelink reception signal.
