Numerology-Based Serving Cell Interruption Thresholds
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Next-generation radiocommunication systems, such as 5G, face challenges in managing serving cell interruptions due to the use of multiple numerologies, which can lead to undefined and uncontrolled interruptions in multicarrier operations, affecting scheduling performance and UE performance consistency.
Innovation Solution
User equipment (UE) and network nodes determine and adapt to different numerologies used in communicating radio signals between cells, obtaining thresholds for signal interruption performance metrics to monitor and maintain interruptions below defined levels, thereby adapting operational tasks to minimize service disruptions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple numerologies are used in multicarrier operations, then adaptability and versatility are improved, but serving cell interruption performance deteriorates due to undefined and uncontrolled interruptions
Solution Approach 1:
The patent applies parameter changes by establishing specific relationships between numerology parameters (subcarrier spacing, cyclic prefix length) and maximum allowed interruption durations. Different numerology configurations are mapped to different interruption thresholds, allowing the system to adapt to multiple numerologies while maintaining controlled interruption performance through defined parameter relationships.
2Productivity
If operations are performed on one serving cell, then productivity is improved, but signal transmission reliability on another serving cell deteriorates due to interruptions
Solution Approach 1:
The patent implements feedback mechanisms where the network monitors serving cell interruption performance metrics and compares them against thresholds derived from numerology relationships. When interruptions exceed acceptable levels, the system adjusts operational parameters or scheduling decisions to maintain reliability while preserving overall productivity.
3Reliability
If interruption thresholds are set to ensure reliability, then signal transmission stability is improved, but operational flexibility deteriorates
Solution Approach 1:
The patent applies dynamics by making interruption thresholds adaptive rather than fixed. The thresholds are dynamically determined based on the numerology configuration being used, allowing the system to maintain appropriate reliability levels while adapting to different operational scenarios and numerology choices.

AI summary
Methods, systems and devices for communicating via signaling are described. The system or device determines at least one first numerology and at least one second numerology used for communicating radio signals in a first cell and a second cell, respectively, wherein the at least one first numerology and the at least one second numerology include one or more parameters which define the radio signals in terms of time and frequency. The system or device obtains, based on at least one of the numerologies, a threshold related to at least one signal interruption performance metric. The system or device monitors or maintains a signal interruption performance on the first cell relative to the threshold.
