Application-Based Frequency Band Biasing for Wireless Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Multiband user devices often unnecessarily retune between frequency bands due to equal probability assignment, which can lead to suboptimal propagation properties for the type of application or service invoked, resulting in performance issues and inefficient resource utilization.
Innovation Solution
An application-based biasing scheme is implemented, where the wireless station controller determines the category of the application or service and selects the appropriate frequency band based on its propagation properties, assigning resources accordingly to ensure optimal performance for real-time or non-real-time applications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If equal probability assignment is used for frequency band selection, then device simplicity is maintained, but application performance deteriorates due to unnecessary retuning and suboptimal propagation properties
Solution Approach 1:
The patent changes the selection probability parameter from equal distribution to application-based differentiated distribution. The wireless station controller adjusts the probability of selecting different frequency bands based on the application category (real-time vs. non-real-time), thereby optimizing propagation properties for each application type while maintaining a relatively simple selection mechanism.
2Adaptability or versatility
If frequency band retuning is performed frequently, then resource allocation flexibility is improved, but network efficiency deteriorates due to unnecessary retuning operations
Solution Approach 1:
The patent applies different resource allocation strategies to different application categories. Real-time applications receive priority handling with optimized frequency band assignment, while non-real-time applications use standard procedures. This localized quality approach ensures that retuning operations are performed only when necessary for specific application types, thereby maintaining network efficiency while preserving resource allocation flexibility.

AI summary
A method performed by a network device includes receiving a request for a service or an application and determining a type of the service or the application selecting a frequency band to provide the service or the application from among multiple frequency bands, where a selection of the frequency band is based on the type of the service or the application. The method further includes providing the service or the application on the selected frequency band.
