Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication technologies face challenges in efficiently managing configuration information for Tracking Reference Signals (TRS) or Channel State Information-Reference Signals (CSI-RS), leading to increased signaling overhead and power consumption in user equipment (UE).
Innovation Solution
The proposed solution involves an information processing method where a base station sends combined configuration information for TRS or CSI-RS, including a set of information elements (IEs) that indicate a resource set, thereby reducing the number of bits required for configuration transmission and minimizing signaling overhead.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If separate configuration information for TRS or CSI-RS is transmitted, then the configuration can be indicated in detail, but the signaling overhead increases
Solution Approach 1:
The patent combines multiple separate configuration information elements (TRS configuration and CSI-RS configuration) into a single unified configuration message. This merging reduces the total signaling overhead while maintaining complete configuration details for both reference signals, directly resolving the contradiction between information completeness and signaling quantity.
Solution Approach 2:
The unified configuration information serves multiple functions simultaneously: it configures both TRS and CSI-RS resources, parameters, and associations in a single transmission. This multi-functionality eliminates the need for separate configuration messages, reducing signaling overhead while preserving all necessary configuration details.
2Reliability
If UE wakes up early to synchronize with SSB, then synchronization is achieved, but power consumption increases
Solution Approach 1:
The patent enables the network to pre-configure TRS or CSI-RS resources with precise timing information that is closer to the Paging Occasion. The UE can use this pre-configured information to wake up later and perform synchronization at the optimal time, rather than waking up early for SSB, thus reducing power consumption while maintaining synchronization reliability.
Solution Approach 2:
The patent changes the timing parameter of the reference signal from SSB (far from PO) to TRS/CSI-RS (close to PO). This parameter change in timing alignment allows the UE to optimize its wake-up time, achieving synchronization closer to the actual paging occasion and reducing unnecessary early wake-up power consumption.
3Ease of operation
If multiple separate IEs are transmitted for resource set configuration, then detailed resource allocation is achieved, but the number of bits increases
Solution Approach 1:
The patent merges multiple separate Information Elements (IEs) for TRS and CSI-RS resource set configuration into a single combined IE structure. This consolidation maintains detailed resource allocation precision for both reference signals while reducing the total number of bits required for transmission by eliminating redundancy and overhead from separate IE structures.
