Base Station Resource Allocation for Whispering and Speaking Areas
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication resource allocation methods in cellular systems face challenges in achieving maximum diversity gain and addressing resource request imbalances between whispering and speaking areas, leading to inefficiencies in frequency reuse and interference management.
Innovation Solution
A communication resource allocation method where a first base station dynamically allocates whispering and speaking resources based on path loss differences between terminals and base stations, adjusting resource ratios and areas to optimize resource utilization and balance requests between whispering and speaking areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a base station continuously allocates specified communication resources to terminals, then resource allocation is simplified, but diversity gain is lost
Solution Approach 1:
The patent applies dynamics by making resource allocation time-varying rather than static. The base station dynamically adjusts resource allocation based on changing channel conditions and terminal positions, allowing the system to adapt to varying requirements and maintain diversity gain while simplifying operation through automated dynamic adjustment
2Productivity
If frequency reuse efficiency is increased by allowing adjacent cells to use common resources, then system capability is improved, but interference between adjacent cells increases
Solution Approach 1:
The patent applies local quality by differentiating resource allocation based on terminal position and channel conditions. Terminals in different locations (whispering area vs. speaking area) receive different resource allocations tailored to their specific interference environments, allowing optimized frequency reuse while managing local interference levels
3Reliability
If resource allocation is optimized for whispering area terminals, then diversity gain is improved, but resource request imbalance occurs
Solution Approach 1:
The patent applies feedback by continuously monitoring resource requests from both whispering and speaking areas and adjusting allocation accordingly. The base station uses feedback information about resource demands and channel conditions to dynamically balance resource distribution, preventing request imbalance while maintaining diversity gain through adaptive resource management

AI summary
A communication resource allocation method for solving resource request imbalance content in a cell is provided. Considering a propagation environment, the base station allocates a whispering resource to a whispering area, the whispering resource being one part of the communication resource and the whispering area being a peripheral area of the first base station, and allocates a speaking resource to a speaking area, the speaking resource being other parts of the communication resource and the speaking area being a border area of a cell. When the resource request of the whispering area is increased, the base station further allocates a part of the speaking resource to the whispering area or increases a ratio of the whispering resource. When the resource request of the speaking area is increased, the base station controls a threshold value for identifying the whispering and speaking areas or increases a ratio of the speaking resource.
