Access Point Channel Resource Usage Reporting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in efficiently managing and allocating data channel resources across multiple access points, leading to suboptimal network performance due to inadequate reporting and resource allocation strategies.
Innovation Solution
A wireless communications apparatus that receives data channel resources from a network controller, allocates them to mobile devices, and reports usage information back to the controller, enabling dynamic adjustment of resource allocation based on loading, interference, and device type, thereby optimizing resource utilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If data channel resources are allocated to multiple mobile devices across multiple access points, then network coverage and user access capability are improved, but resource allocation efficiency deteriorates due to inadequate reporting mechanisms
Solution Approach 1:
The patent implements a feedback mechanism where access points report channel usage information (number of granted and denied system acquisition requests) to the network controller. This feedback enables the controller to dynamically adjust resource allocation based on actual network conditions, resolving the contradiction between expanded network coverage and resource allocation efficiency.
2Device complexity
If the network controller allocates fixed data channel resources to access points, then resource management is simplified, but network performance deteriorates due to inability to adapt to changing conditions
Solution Approach 1:
The patent transitions from static fixed resource allocation to dynamic resource allocation. The network controller adjusts the number of data channel resources allocated to each access point based on real-time channel usage reports, allowing the system to adapt to changing network conditions while maintaining manageable complexity through automated adjustment.
3Measurement precision
If detailed channel usage information is reported to the network controller, then resource allocation accuracy is improved, but signaling overhead and processing complexity increase
Solution Approach 1:
The patent extracts only the essential channel usage information needed for resource allocation decisions - specifically the number of granted and denied system acquisition requests. This selective reporting provides sufficient accuracy for resource allocation while minimizing signaling overhead and processing complexity compared to reporting all possible channel parameters.

AI summary
Systems and methodologies are described that facilitate common data channel resource usage report for receiving additional channel resources in a wireless network. An access point can initially receive a set of channel resources from a network controller for providing wireless network access to one or more devices. The access point can grant and/or deny requests for one or more of the channel resources from a plurality of devices and can feedback information to the network controller regarding the granting/denying. The network controller can determine a load on the access point based at least in part on the feedback information and adjust channel resource allocation based on the load. Thus/ where an access point has granted resources close to capacity to one or more devices, the network controller can provide additional resources to the access point based on received feedback information related to the granted resources.
