Radio Resource Management for Power Threshold Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile communication networks face increasing energy consumption due to rising mobile device subscriptions, and existing radio resource management systems do not effectively manage power consumption of user equipment within defined thresholds, potentially exceeding energy limits while maintaining quality-of-service.
Innovation Solution
A method where a radio resource management entity in a mobile communication network dynamically assigns different sets of radio resources to user equipment based on power consumption information, ensuring that power usage stays within predefined thresholds by considering multiple radio access technologies and signal transmission schemes, and prioritizing power efficiency or quality-of-service as needed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional radio resource management is used to assign radio resources, then quality-of-service needs are fulfilled, but power consumption of user equipment exceeds predefined thresholds
Solution Approach 1:
The patent implements dynamic radio resource allocation by continuously monitoring user equipment power consumption and adjusting resource assignments in real-time. The radio resource management entity dynamically modifies transmission parameters such as modulation schemes, coding rates, and resource block allocations based on live power consumption data, enabling the system to adapt between quality-of-service requirements and power conservation needs.
Solution Approach 2:
The patent changes key transmission parameters including modulation and coding scheme (MCS), resource block allocation, and transmission power levels to optimize the balance between quality-of-service and power consumption. By adjusting these parameters dynamically, the system can maintain acceptable service quality while keeping power consumption within predefined thresholds.
2Productivity
If radio resources are allocated to maximize network efficiency, then data transmission is optimized, but power consumption increases beyond acceptable limits
Solution Approach 1:
The patent employs feedback mechanisms where the radio resource management entity receives real-time power consumption information from user equipment and uses this feedback to adjust resource allocation decisions. This closed-loop control ensures that network efficiency optimizations do not cause power consumption to exceed acceptable limits, as the system continuously monitors and responds to power usage data.
Solution Approach 2:
The patent applies partial resource allocation strategies where instead of allocating maximum resources to maximize network efficiency, the system allocates only the necessary minimum resources required to meet quality-of-service thresholds. This partial action approach prevents excessive power consumption while maintaining adequate service levels.
3Adaptability or versatility
If multiple radio access technologies are used to serve user equipment, then service coverage is expanded, but power consumption management becomes more complex
Solution Approach 1:
The patent implements a universal radio resource management framework that handles multiple radio access technologies (e.g., LTE, 5G, Wi-Fi) through a unified power consumption monitoring and control mechanism. The radio resource management entity uses consistent evaluation criteria and control logic across different RATs, simplifying power management complexity while maintaining expanded service coverage through multi-technology support.

AI summary
A method for power consumption management of a user equipment using a mobile communication network includes: in a first step, a set of first radio resources is assigned, by a radio resource management entity, to the user equipment for transmitting uplink data and/or receiving downlink data; in a second step, subsequent to the first step, power consumption information is obtained by the radio resource management entity, the power consumption information indicating that a current power consumption of the user equipment using the assigned set of first radio resources is above a predefined upper power consumption threshold or below a predefined lower power consumption threshold; and in a third step, subsequent to the second step, a set of second radio resources is assigned, by the radio resource management entity, to the user equipment for transmitting uplink data and/or receiving downlink data.
