UE Power-Saving Configuration Feedback for 5G Radio Setup
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems, particularly 5G NR, lack the ability for base stations to make effective radio configurations for user equipment (UE) due to insufficient understanding of UE-specific factors such as power status and user preferences, leading to inefficient power usage and performance trade-offs.
Innovation Solution
The UE provides configuration parameters and preferences, such as power-saving settings, to the base station, enabling it to determine more optimized radio configurations based on the UE's knowledge of its own status and anticipated usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If the network uses standard radio configuration procedures, then the configuration process is simple and fast, but the power management is suboptimal and does not consider UE-specific conditions
Solution Approach 1:
The patent implements feedback mechanisms where the UE reports its power status, capability information, and preferred configurations to the network. The network uses this feedback to adjust radio configurations dynamically, enabling optimal power management while maintaining manageable complexity through structured information exchange.
Solution Approach 2:
The patent applies preliminary action by having the UE provide capability information and power status reports before the network makes configuration decisions. This advance information allows the network to pre-configure optimal parameters for power saving, reducing the need for complex real-time adjustments later.
2Use of energy by moving object
If the network implements UE-specific power saving configurations, then power management improves, but the signaling overhead and configuration complexity increase
Solution Approach 1:
The patent extracts only the essential power-related configuration parameters and UE capability information needed for power saving decisions. By selecting and transmitting only the most relevant parameters (such as preferred DRX parameters, power saving preferences, and key capability indicators), the patent reduces signaling overhead while maintaining effective UE-specific power management.
3Productivity
If the network configures radio parameters without UE input, then the configuration process is fast, but the configurations do not optimize for user preferences and UE conditions
Solution Approach 1:
The patent enables self-service by allowing the UE to autonomously determine and report its preferred radio configuration parameters based on its power status, capability information, and user preferences. The network then uses these UE-determined preferences to configure radio parameters, improving communication efficiency while keeping the configuration process relatively simple through the UE's self-assessment capabilities.

AI summary
An UE transmits at least one UE configuration parameter to a base station comprising at least one preferred parameter for a UE configuration, e.g., in addition to a preferred setting for a delay budget report. The UE then receives a configuration from the base station based, at least in part, on the at least one UE configuration parameter transmitted to the base station. Additionally, a base station receives the at least one UE configuration parameter from a UE comprising at least one preferred parameter for a UE configuration, e.g., in addition to a preferred setting for a delay budget report. The base station then configures the UE using the at least one UE configuration parameter received from the UE.
