Dynamic Signaling for Wireless Coverage Enhancement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in dynamically enhancing coverage for user equipment (UEs) due to degraded beam performance on narrow beams, which affects communication quality and efficiency, especially in high-bandwidth frequency ranges like 5G NR.
Innovation Solution
Implementing dynamic signaling for wireless coverage enhancement by activating specific parameters such as repetition, frequency resource allocation, time resource allocation, or payload size parameters in a single communication to UE(s), transmitted through DCI, MAC-CE, or GC-PDCCH, based on beam performance thresholds, allowing UEs to adjust their communication methods accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple separate signaling communications are used to activate coverage enhancement parameters, then parameter configuration flexibility is improved, but signaling overhead increases
Solution Approach 1:
The patent combines multiple coverage enhancement parameters (repetition factor, frequency resource allocation, time resource allocation, payload size) into a single signaling communication. This merging approach reduces the number of separate signaling messages while maintaining the ability to configure multiple parameters simultaneously, thus reducing signaling overhead without sacrificing configuration flexibility.
Solution Approach 2:
The single signaling communication is designed to carry multiple types of coverage enhancement parameters through a unified structure. This multi-functional signaling message can activate different parameter types (repetition, frequency, time, payload size) based on the UE's specific coverage enhancement needs, providing universal applicability across different parameter configurations.
2Reliability
If dynamic parameter activation is implemented, then communication quality is improved, but radio resource consumption increases
Solution Approach 1:
The patent implements dynamic activation of coverage enhancement parameters through received signaling, allowing the system to adapt parameter configurations in real-time based on current communication conditions. This dynamic approach enables the UE to activate only the specific parameters needed for its current coverage enhancement requirements, improving communication quality while avoiding the continuous resource consumption that would result from always using maximum enhancement settings.
