Adaptive Wireless Resource Allocation via Dynamic Thresholds
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face challenges in achieving both power-saving and congestion control, as existing methods either prioritize power-saving at the expense of increased congestion or vice versa, due to the use of fixed threshold values for channel quality and congestion management.
Innovation Solution
A method that dynamically calculates an index value based on channel quality and measures congestion degree to determine the allocation of wireless resources, using a threshold value that adapts to the measured congestion level, ensuring efficient resource allocation and minimizing power consumption while preventing congestion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If a fixed threshold value is used for channel quality to prioritize power-saving, then power consumption is reduced, but congestion occurs due to insufficient resource allocation to receivers in bad state
Solution Approach 1:
The patent applies dynamics by making the threshold value adaptive rather than fixed. The threshold is dynamically adjusted based on real-time channel quality measurements and congestion degree assessments. When channel quality is good, the threshold is raised to prioritize power-saving; when congestion is detected, the threshold is lowered to ensure adequate resource allocation, thus resolving the contradiction between power-saving and congestion control
Solution Approach 2:
The patent implements feedback mechanisms where the scheduler continuously monitors channel quality and congestion degree, using this information to adjust the threshold value. This closed-loop feedback allows the system to respond to changing network conditions, maintaining optimal balance between power consumption and congestion prevention
2Loss of energy
If wireless resources are allocated only to receivers in good state to maximize power-saving, then transmission power is reduced, but throughput decreases due to limited allocation opportunities
Solution Approach 1:
The patent changes the parameter of threshold value based on network conditions. By adjusting the threshold dynamically, the system can shift the balance between the number of receivers receiving resources and the efficiency of each transmission. This allows maximizing throughput when needed while maintaining power-saving when channel conditions permit

AI summary
A communication device includes an calculation unit, a measuring unit, a setting unit, and a determination unit. The calculation unit calculates an index value according to each of the other communication devices for determining whether to let a wireless resource utilized for communications with the other communication device be a candidate allocated to the other communication device based on the quality of a channel to the other communication device. The measuring unit measures a congestion degree between itself and the other communication device. The setting unit calculates a threshold value for determining whether to let the wireless resource be the candidate allocated to the other communication device based on the measured congestion degree. The determination unit compares the index value with the threshold value to determine whether to let the wireless resource be the candidate allocated to the other communication device.
