Terminal-Driven Resource Allocation for 5G Overheating Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increased communication speed in wireless devices leads to higher power consumption and overheating issues, which are not effectively addressed by existing methods, resulting in LTE fallback and reduced 5G connection maintenance time.
Innovation Solution
A terminal in a wireless communication system initiatively controls resource allocation by transmitting capability and overheating assistance messages to a base station, requesting additional resources based on data throughput to manage power consumption and prevent overheating.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If communication speed is increased to provide higher data throughput, then productivity is improved, but power consumption increases and overheating occurs
Solution Approach 1:
The terminal dynamically adjusts resource allocation parameters (number of CCs, MIMO layers, bandwidth) based on real-time temperature conditions and data throughput requirements. The base station receives capability information indicating maximum supported resources and dynamically allocates appropriate resource levels, allowing the system to adapt between high-performance and power-saving states rather than operating at fixed maximum capacity.
2Reliability
If maximum resources are allocated to maintain 5G connection, then connection stability is improved, but temperature increases causing overheating
Solution Approach 1:
The system changes operational parameters (resource allocation levels) based on temperature conditions. When temperature is acceptable, higher resource allocation maintains strong 5G connection. When temperature approaches thresholds, the terminal signals the base station to reduce resource allocation parameters, thereby reducing power consumption and temperature while maintaining connection stability through adaptive parameter adjustment.
3Loss of energy
If resource allocation is reduced to lower power consumption, then power efficiency is improved, but data throughput decreases
Solution Approach 1:
The terminal provides feedback to the base station about its temperature status and data throughput requirements through capability information messages. The base station uses this feedback to allocate resources at appropriate levels - not maximum but sufficient for current needs - achieving power efficiency without unnecessarily sacrificing throughput. The system continuously monitors and adjusts based on actual performance requirements.
