Radio Network Node Targeting UEs Near Radio Degradation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication networks inefficiently handle radio degradation by broadcasting location information to all user equipment (UEs) in a cell, leading to unnecessary resource consumption and processing for UEs that are unlikely to be affected by the degradation.
Innovation Solution
A radio network node selectively identifies target UEs near the area of radio degradation and transmits a notification only to those UEs, reducing unnecessary location calculations and resource consumption by using velocity, external maps, and degradation report analysis to determine the severity and location of the degradation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the radio network node broadcasts location information to all UEs in a cell, then all UEs are informed about radio degradation, but unnecessary resource consumption and processing occur for UEs that are unlikely to be affected
Solution Approach 1:
The patent segments the cell area into different zones based on proximity to the degraded area. Instead of notifying all UEs uniformly, the network node identifies and notifies only those UEs located in or near the degraded area, thereby segmenting the notification process by spatial location to reduce unnecessary energy consumption.
Solution Approach 2:
The patent applies local quality by providing different treatment to different spatial locations within the cell. UEs in the degraded area receive notifications while UEs far from the degraded area do not, making the notification system adaptive to local conditions rather than applying a uniform approach across the entire cell.
2Reliability
If the radio network node notifies all UEs about radio degradation, then comprehensive coverage is achieved, but network signaling overhead and processing load increase
Solution Approach 1:
The patent segments the UE population into two groups: those located in or near the degraded area who receive notifications, and those far from the degraded area who do not. This segmentation reduces the number of UEs that need to process degradation information, thereby reducing network signaling overhead and improving overall network efficiency.
Solution Approach 2:
The patent applies partial action by notifying only the subset of UEs that are actually affected by or at risk of entering the degraded area, rather than notifying all UEs in the cell. This partial notification approach maintains sufficient degradation awareness while reducing network processing load.
3Measurement precision
If UEs continuously calculate their location to check for degradation areas, then accurate degradation detection is achieved, but power consumption increases
Solution Approach 1:
The patent applies preliminary action by having the network node proactively notify UEs about degraded areas before the UEs need to calculate their locations to check for degradation. The network node uses its knowledge of UE locations and degraded area positions to determine which UEs should be notified, eliminating the need for continuous UE location calculations.
Solution Approach 2:
The patent enables the network node to perform the location analysis and notification decision-making function that would otherwise require continuous UE computation. By transferring this computational burden from the UE to the network node, the system maintains accurate degradation detection while significantly reducing UE power consumption.

AI summary
A method performed by a radio network node for handling a radio degradation in a wireless communication network. The radio network node detects the radio degradation in a radio coverage area served by the radio network node. The radio network node further identifies at least one target wireless device to inform about the radio degradation. The radio network node then transmits a notification of the detected radio degradation to the at least one identified target wireless device.
