Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication networks face challenges in dynamically controlling power consumption across various elements while maintaining performance, as the complexity of adding more functionality increases energy usage and requires finer granular control to reduce energy costs.
Innovation Solution
A method and system that allow wireless communication nodes to transmit configuration messages to User Equipment (UE) for activating, deactivating, or updating elements such as cells, frequency layers, TRPs, beams, and antennas, enabling fine-grained power management by targeting specific network elements for power saving without significantly impacting system performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If more functionality is added to wireless communication networks, then service capability is improved, but power consumption increases
Solution Approach 1:
The patent segments the wireless communication system into multiple controllable elements including cells, frequency layers, carriers, beams, and antenna panels. Each element can be independently activated or deactivated based on traffic conditions, allowing the system to maintain functionality where needed while reducing power consumption in inactive segments.
Solution Approach 2:
The patent implements dynamic activation and deactivation of network elements based on real-time traffic conditions. The system transitions from static operation to dynamic operation where elements are activated only when needed, enabling the system to adapt its power consumption to actual service requirements rather than maintaining all elements active continuously.
2Loss of energy
If finer granular control is implemented for power management, then power consumption is reduced, but system complexity increases
Solution Approach 1:
The patent divides the network into discrete controllable segments (cells, frequency layers, carriers, beams, antenna panels) that can be independently managed. This segmentation enables fine-grained power control by allowing individual segments to be activated or deactivated based on local traffic conditions without requiring complete system reconfiguration.
Solution Approach 2:
The patent changes operational parameters of network elements by transitioning them between active and inactive states. This parameter change approach enables power saving by modifying the operational state of individual elements rather than requiring complex reconfiguration of the entire system, thus reducing control complexity while achieving fine-grained power management.
3Loss of energy
If elements are deactivated to save power, then energy consumption is reduced, but system performance may deteriorate
Solution Approach 1:
The patent implements dynamic activation and deactivation strategies where elements are deactivated during low-traffic periods to save energy and reactivated when traffic conditions require them. This dynamic approach ensures that system performance is maintained during high-demand periods while achieving energy savings during low-demand periods.
Solution Approach 2:
The patent employs feedback mechanisms where traffic conditions are continuously monitored and used to determine which elements should be activated or deactivated. This feedback loop ensures that element activation decisions are based on actual system needs, maintaining performance where required while enabling power saving where traffic conditions permit.
