Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face challenges in efficiently managing dynamic parameter settings for uplink control information (UCI) reporting, leading to increased signaling overhead and latency, especially in next-generation mobile communication systems requiring high data traffic capacity and low latency.
Innovation Solution
A method and apparatus that allow for changing setting values of UCI parameters without reconfiguring the configuration information, enabling flexible UCI reporting operations and reducing signaling overhead and latency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If configuration information for UCI parameters is reconfigured to change setting values, then parameter settings can be updated, but signaling overhead increases and latency increases
Solution Approach 1:
The configuration information is segmented into two parts: static configuration parameters that remain fixed, and dynamic parameter indicators that can be quickly updated. This allows the system to change parameter settings by transmitting only the dynamic portion rather than reconfiguring the entire configuration information, thereby reducing latency and signaling overhead while maintaining adaptability.
Solution Approach 2:
The system performs preliminary configuration by establishing a framework of configuration information that includes predefined parameter sets. When parameter changes are needed, the system activates pre-defined parameter sets or updates only the dynamic indicator portions, avoiding the need for complete reconfiguration and thus reducing the time required for parameter updates.
2Adaptability or versatility
If configuration information for UCI parameters is reconfigured to change setting values, then parameter settings can be updated, but signaling overhead increases
Solution Approach 1:
The configuration information is segmented into static and dynamic components. Only the dynamic parameter indicators need to be transmitted when changes are required, significantly reducing signaling overhead compared to transmitting complete configuration information. This segmentation allows flexible parameter updates with minimal information exchange.
Solution Approach 2:
Instead of transmitting complete configuration information, the system uses compact indicators or references that point to predefined parameter sets. These indicators act as copies or shortcuts that convey the essential parameter changes without duplicating the full configuration data, thereby reducing signaling overhead while maintaining the ability to update parameters flexibly.
3Adaptability or versatility
If multiple functionality/models are configured for UCI reporting, then reporting flexibility improves, but system complexity increases
Solution Approach 1:
The configuration information structure is designed to be universal and multi-functional, accommodating multiple UCI reporting functionalities through a unified framework. This allows the system to support multiple models and reporting types without creating separate complex configuration structures for each, thereby maintaining reporting flexibility while managing system complexity through standardization.
