Unified Resource Configuration for User Group Cooperation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In next-generation communication systems, the configuration of bandwidth parts (BWP) for user equipment cooperation leads to wastage of time-frequency resources and reduced resource utilization efficiency, especially when different resource parameter sets are used for different terminal apparatuses within a user group.
Innovation Solution
A method where a network apparatus configures and communicates a shared resource element and time-frequency resource to multiple terminal apparatuses within a user group using scrambled configuration and control information, allowing simultaneous communication and optimizing resource allocation based on service requirements and capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If different resource parameter sets are configured for different terminal apparatuses in a user group, then each terminal apparatus can be optimized for its specific service requirements, but time-frequency resources are wasted and resource utilization efficiency is reduced
Solution Approach 1:
The patent merges the resource configuration process by introducing a network apparatus that centrally manages and allocates time-frequency resources to multiple terminal apparatuses within a user group. Instead of each terminal independently configuring resources, the network apparatus sends unified configuration information to all terminals, enabling them to share the same time-frequency resources for cooperative transmission, thus improving resource utilization efficiency while maintaining service-specific optimization through the unified configuration.
2Adaptability or versatility
If separate configuration information is sent to each terminal apparatus, then individual terminal requirements are met, but downlink control signaling overhead increases
Solution Approach 1:
The patent combines multiple separate configuration messages into a single unified configuration information message that is sent by the network apparatus to all terminal apparatuses in the user group simultaneously. This unified configuration contains the necessary resource parameter sets that can be applied by each terminal according to its specific requirements, thereby reducing downlink control signaling overhead while still meeting individual terminal configuration needs.
3Reliability
If different cooperative time-frequency resources are configured for terminal apparatuses in a user group, then individual transmission requirements are satisfied, but resource waste occurs and utilization efficiency decreases
Solution Approach 1:
The patent segments the configuration information into different resource parameter sets within a unified configuration message. The network apparatus divides the time-frequency resources into multiple parameter sets that can be selectively applied by different terminal apparatuses based on their specific transmission requirements. This segmentation allows terminals to use appropriate resources for reliable transmission while overall resource utilization is improved through coordinated allocation.
Solution Approach 2:
The patent introduces dynamic resource allocation where the network apparatus can flexibly assign different resource parameter sets to different terminals within the same user group based on real-time service requirements. The configuration information includes multiple resource parameter sets that can be dynamically selected and applied, allowing the system to adapt to changing transmission needs while maintaining efficient resource utilization through centralized control.
