Reference Signal Generation via UE Capability-Based Configuration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Generating reference signals in wireless communication systems is computationally intensive and inefficient, as existing methods do not effectively utilize user equipment (UE) preferences for resource configuration, leading to suboptimal resource allocation and increased bandwidth usage.
Innovation Solution
The system allows user equipment (UE) to transmit reference signal configuration preferences to the base station, enabling the base station to configure and generate reference signals based on UE-specific capabilities and environmental conditions, using advanced protocols like 5G NR and AI/ML for efficient resource management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional reference signal generation methods are used, then reference signals can be generated, but significant computing resources and time are consumed
Solution Approach 1:
The UE device autonomously determines its own capability level and selects appropriate reference signal generation methods based on its capabilities, eliminating the need for the base station to continuously query and configure each UE individually. This self-configuration reduces signaling overhead and processing complexity while maintaining generation quality.
Solution Approach 2:
The patent introduces capability-based parameter selection where different UE capabilities (e.g., AI/ML processing ability, memory resources) map to different reference signal generation parameters such as sequence length, frequency spacing, and generation algorithms. This allows the system to adapt resource consumption to actual UE capabilities rather than using fixed conservative parameters.
2Reliability
If reference signals are generated with high resource allocation, then signal quality is maintained, but bandwidth usage increases
Solution Approach 1:
The patent applies different reference signal generation configurations to different UE devices based on their individual capabilities and service requirements. High-capability UEs may use more efficient generation methods with lower bandwidth overhead, while maintaining adequate signal quality for their specific applications. This localized optimization prevents uniform over-provisioning across all UEs.
Solution Approach 2:
The reference signal configuration is made dynamic and adaptive rather than static. The system can adjust reference signal parameters such as density, frequency spacing, and time-domain allocation based on changing UE capabilities, channel conditions, and traffic requirements. This dynamic adaptation allows bandwidth consumption to be optimized in real-time while maintaining signal quality.
