Wireless UE Power Saving Through Dynamic Traffic Configuration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems fail to adapt quickly to traffic changes, leading to unnecessary power consumption in user equipment (UE) due to static configuration parameters, which is particularly pronounced in advanced communication scenarios like URLLC and eMBB.
Innovation Solution
Implementing power saving schemes at the network-side device, such as a base station, by configuring user equipment (UE) in a power saving mode based on various parameters, including enhanced time domain processing, DRX, BWP, CA, MIMO, and PDCCH monitoring, to reduce unnecessary power consumption.

Engineering Contradiction Analysis
1Use of energy by moving object
If static configuration parameters are used in user equipment, then device complexity is reduced and ease of operation is improved, but power consumption increases due to inability to adapt to traffic changes
Solution Approach 1:
The patent implements dynamic configuration parameters that can be adjusted in real-time based on traffic conditions. The network device monitors traffic patterns and dynamically configures parameters such as subcarrier spacing, cyclic prefix length, and resource allocation to match current traffic demands, allowing the UE to adapt without increasing fundamental device complexity.
Solution Approach 2:
The patent changes physical and operational parameters of the UE based on traffic conditions. By modifying parameters like bandwidth allocation, modulation schemes, and transmission power dynamically, the system achieves adaptability to varying traffic loads while managing power consumption effectively.
2Adaptability or versatility
If configuration parameters are updated frequently to adapt to traffic changes, then adaptability is improved, but device complexity and processing overhead increase
Solution Approach 1:
The patent employs pre-configured parameter sets and templates that are prepared in advance for different traffic scenarios. When traffic conditions change, the UE switches between pre-defined configurations rather than calculating new parameters in real-time, reducing processing complexity while maintaining adaptability.
Solution Approach 2:
The UE is equipped with autonomous capabilities to monitor traffic conditions and select appropriate pre-configured parameter sets without requiring complex real-time calculations or frequent network interventions, thereby reducing processing overhead while maintaining adaptability.
