Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication networks face challenges in efficiently managing energy consumption in mobile stations, particularly in dense and heterogeneous networks, where increased data traffic leads to rapid battery depletion due to high energy costs and interference, without effective solutions for energy-efficient radio access resource allocation.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If network densification is implemented to increase radio access resources and meet growing traffic demand, then system throughput and capacity are improved, but energy consumption increases significantly
Solution Approach 1:
The patent implements dynamic resource allocation where the network node continuously monitors mobile station parameters (channel quality, speed, energy status) and adapts radio access resource allocation in real-time. This allows the system to provide high throughput when needed while reducing resource allocation and energy consumption during periods of lower demand or when mobile stations are energy-constrained.
Solution Approach 2:
The patent changes operational parameters by considering mobile station energy status, channel conditions, and speed in the resource allocation decision process. By adjusting allocation based on these parameters, the system optimizes the balance between throughput delivery and energy consumption, avoiding unnecessary energy expenditure when mobile stations are energy-constrained or channel conditions are poor.
2Productivity
If multiple radio access resources are allocated to mobile stations to improve throughput, then data transmission capacity increases, but energy consumption at mobile stations increases rapidly
Solution Approach 1:
The patent incorporates mobile station energy status as a key parameter in the resource allocation decision. The network node receives energy status information from mobile stations and adjusts the number and type of radio access resources allocated accordingly, ensuring that throughput requirements are met while preventing excessive energy consumption that would deplete mobile station batteries rapidly.
Solution Approach 2:
The patent implements a feedback mechanism where mobile stations report their energy status and channel conditions to the network node, which then adjusts resource allocation in subsequent transmission time intervals. This closed-loop control ensures that resource allocation remains optimized for both throughput and energy efficiency based on current mobile station states.
3Ease of operation
If radio access resources are allocated without considering mobile station energy status, then resource allocation simplicity is maintained, but mobile station battery life decreases due to high energy consumption
Solution Approach 1:
The patent enables mobile stations to self-report their energy status and capability parameters to the network node. This allows the network node to make informed allocation decisions without requiring complex energy management logic at the network side, maintaining operational simplicity while extending battery life through energy-aware resource allocation.
4Device complexity
If traditional resource allocation methods are used in dense networks, then implementation complexity is low, but interference increases leading to higher energy costs
Solution Approach 1:
The patent introduces channel quality and mobile station speed as additional parameters in the resource allocation process. By considering these parameters, the network node can allocate resources more efficiently, reducing interference through better resource matching while maintaining relatively simple implementation through enhanced allocation criteria rather than complex interference coordination mechanisms.
