Uu and Sidelink Priority Scheduling for QoS Conflict Resolution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sidelink communication systems face transmission conflicts when multiplexing uplink transmission resources, leading to postponed transmission of urgent data and reduced quality of service (QoS) due to inadequate priority handling between Uu and sidelink data.
Innovation Solution
Implementing a method to jointly configure priorities for Uu and sidelink data, allowing for at least two priorities for sidelink data, and adjusting transmission periods and power configurations to prioritize higher priority data for transmission, thereby resolving conflicts and improving QoS.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single priority level is used for sidelink data transmission, then the transmission conflict resolution is simplified, but the quality of service (QoS) deteriorates due to postponement of urgent data
Solution Approach 1:
The patent segments sidelink data into multiple priority levels (at least two different priorities) to differentiate urgency degrees. This segmentation allows the system to handle different types of sidelink data with appropriate priority treatment, resolving the contradiction by making the priority configuration more granular while maintaining manageable complexity through structured priority levels.
Solution Approach 2:
The patent changes the priority parameter from a single uniform value to multiple distinguishable priority levels. By introducing at least two different priority values for sidelink data, the system can dynamically adjust transmission preferences based on data urgency, thereby improving QoS while keeping the priority mechanism relatively simple through discrete parameter values.
2Reliability
If multiple priorities are configured for sidelink data, then the QoS is improved by prioritizing urgent data transmission, but the device complexity increases due to more complex priority configuration and management
Solution Approach 1:
The patent implements dynamic priority assignment where at least two different priority levels can be assigned to sidelink data based on real-time urgency requirements. This dynamic approach allows the system to adapt priority configurations flexibly without requiring complex permanent structures, improving QoS while managing complexity through adaptive rather than static configurations.
Solution Approach 2:
By using discrete priority parameter values (at least two distinct priorities), the patent simplifies the complexity of priority management compared to continuous or fine-grained priority schemes. The parameter change approach allows for improved QoS through differentiated priority treatment while maintaining relatively simple configuration and management overhead.
3Device complexity
If transmission resources are allocated without considering data urgency, then the resource allocation is simple and uniform, but urgent data transmission is postponed resulting in low QoS
Solution Approach 1:
The patent applies local quality by assigning different priority levels to different sidelink data packets based on their specific urgency requirements. Instead of uniform treatment, each data transmission can have its priority locally adjusted, allowing urgent data to be preferentially transmitted while maintaining relatively simple overall resource allocation mechanisms through localized priority assignments.

AI summary
Disclosed in embodiments of the present application are a data processing method and apparatus, a communication device and a storage medium. The data processing method comprises: issuing the priority of a Uu logic channel. When Uu data and sidelink data conflict, the priority of the Uu logic channel of the Uu data and the priority of the sidelink data are jointly used to select data which has the higher priority among the Uu data and the sidelink data for priority sending; and the sidelink data has at least two priorities.
