Terminal Resource Conflict Handling for Scheduled and Autonomous Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The LTE system only supports single resource allocation modes, while the NR system requires simultaneous operation in network device scheduling and terminal autonomous selection modes, leading to resource conflicts that need to be resolved.
Innovation Solution
A method and device for discarding conflicting resources and communicating the reason for discarding to the network device, allowing for timely resolution of conflicts between resources acquired through different allocation modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the terminal operates in both network device scheduling mode and terminal autonomous selection mode simultaneously, then the system can support more diverse QoS services, but resource conflicts occur between the two modes
Solution Approach 1:
The patent changes the resource allocation parameters by introducing a conflict detection and resolution mechanism that dynamically adjusts resource selection based on the operational mode. When a resource conflict is detected between mode 1 and mode 2 resources, the terminal switches to using only mode 2 resources for that particular transmission, thereby resolving the conflict while maintaining both operational modes for different service types.
2Reliability
If the terminal discards a conflicted resource, then resource conflict is resolved, but the network device needs to be informed to maintain scheduling performance
Solution Approach 1:
The patent implements a feedback mechanism where the terminal sends an indication message to the network device when it discards a mode 1 resource due to conflict with a mode 2 resource. This feedback allows the network device to update its scheduling decisions and avoid allocating the same resource to the terminal, thereby maintaining scheduling performance while resolving the resource conflict.
3Reliability
If the terminal uses mode 1 resource allocation, then network device scheduling performance is maintained, but resource conflicts arise when mode 2 resources are also needed
Solution Approach 1:
The patent introduces dynamic resource allocation where the terminal can switch between mode 1 and mode 2 resource usage based on real-time conflict detection. The system dynamically adjusts the resource allocation strategy: when no conflict exists, mode 1 resources are used for reliable scheduling; when conflict is detected, the terminal dynamically switches to mode 2 resources, thereby maintaining both scheduling performance and allocation flexibility.

AI summary
An embodiment of the present disclosure provides a processing method and device. The method includes: discarding a first resource when the first resource conflicts with a second resource; and transmitting first information to a network device, wherein the first information indicates that a terminal discards the first resource and/or a reason why the terminal discards the first resource, the first resource is a resource acquired by the terminal based on a network device scheduling mode, and the second resource is a resource acquired by the terminal based on a terminal autonomous selection mode.
