Dynamic Error Correction Target Adjustment for Wireless Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless communication networks fail to efficiently use UE location to optimize error correction targets, leading to suboptimal error correction and increased retransmissions due to static error correction settings that do not account for UE concentrations.
Innovation Solution
A wireless access node dynamically adjusts the error correction target based on the location and intensity of UE concentrations by identifying concentrations through UE reports and signal strength, modifying the target to allow more errors at edge locations and fewer errors at adjacent locations, thereby optimizing error correction and reducing unnecessary retransmissions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If static error correction targets are used, then device complexity is reduced, but network efficiency deteriorates due to unnecessary retransmissions
Solution Approach 1:
The error correction target is transformed from a static value to a dynamic parameter that automatically adjusts based on UE location. The system continuously monitors UE position and modifies the error correction target accordingly, allowing higher tolerance at edge locations and stricter tolerance at adjacent locations, thereby optimizing network efficiency without increasing system complexity
Solution Approach 2:
The error correction target parameter is changed dynamically based on UE location parameters. By linking the error correction target to location-based conditions, the system automatically adapts the parameter values to match network conditions, reducing unnecessary retransmissions while maintaining appropriate error correction standards
2Productivity
If error correction target is increased at edge locations, then retransmissions are reduced, but data reliability may worsen
Solution Approach 1:
Different error correction targets are applied to different geographic locations within the network coverage area. Edge locations receive higher error correction targets (more tolerant) while adjacent locations maintain lower targets (stricter), allowing each location to operate with optimized parameters suited to its specific conditions
3Reliability
If error correction target is decreased at adjacent locations, then data reliability is improved, but network efficiency deteriorates due to excessive error correction
Solution Approach 1:
The system implements location-specific error correction policies where adjacent locations with strong signal conditions receive stricter error correction targets to ensure high reliability, while edge locations receive more tolerant targets to maximize throughput, optimizing both reliability and efficiency simultaneously

AI summary
A wireless access node controls error correction for wireless User Equipment (UEs). A radio wirelessly exchanges data with the wireless UEs and exchanges the data with a baseband unit. Some of the data is corrupt or missing. The baseband unit exchanges redundant data with the radio to replace a portion of the corrupt or missing data per an error correction target. The radio wirelessly exchanges the redundant data with the wireless UEs. The baseband unit identifies a concentration of the UEs at a location and responsively modifies the error correction target based on the location. The radio wirelessly exchanges additional data with the wireless UEs and exchanges the additional data with the baseband unit. Some of the additional data is corrupt or missing. The baseband unit exchanges redundant data with the radio to replace a portion of the corrupt or missing additional data per the modified error correction target.
