Multi-Cell Associated ID Grouping for RRC Configuration Consistency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current AI/ML model management in New Radio (NR) systems face inefficiencies in managing multiple cells due to frequent RRC reconfigurations and lack of clear mechanisms for maintaining consistency of network-side additional conditions across cells, particularly in complex cell aggregation scenarios.
Innovation Solution
A wireless transceiver unit (WTRU) is configured to receive and utilize associated identification (ID) groups and radio resource control (RRC) configurations, enabling efficient activation of cells based on shared or delta configurations to minimize reconfigurations and maintain consistency across multiple cells.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If RRC reconfiguration is performed for every cell individually, then each cell can be configured with appropriate AI/ML model parameters, but the frequency of reconfigurations increases significantly leading to network overhead and inefficiency
Solution Approach 1:
The patent segments the configuration management by introducing associated ID groups that can be shared across multiple cells. Instead of managing each cell's AI/ML configuration independently, the system divides configuration into cell-specific parameters and group-shared parameters, reducing redundant reconfigurations while maintaining individual cell accuracy.
Solution Approach 2:
The patent implements universality by allowing associated ID groups to serve multiple cells simultaneously. A single associated ID group configuration can be applied across multiple cells, enabling one configuration set to fulfill the AI/ML model management function for several cells, thereby reducing overall reconfiguration frequency and network overhead.
2Reliability
If separate associated IDs are used for each cell, then consistency of network-side additional conditions can be maintained per cell, but the complexity of managing multiple cells increases
Solution Approach 1:
The patent merges the management of associated IDs by introducing associated ID groups that can be shared across multiple cells. Instead of treating each cell's associated ID management as a separate entity, the system combines them into groups where multiple cells can reference the same group, reducing management complexity while preserving per-cell consistency through group-specific configurations.
Solution Approach 2:
The patent adds a new dimension to associated ID management by organizing IDs into hierarchical groups. This dimensional change allows the system to manage associated IDs at two levels: the group level for shared configurations across multiple cells, and the cell level for specific adaptations, thereby simplifying multi-cell management while maintaining consistency.
3Adaptability or versatility
If AI/ML model complexity is increased to solve more complex problems, then the problem-solving capability improves, but the configuration and management overhead increases
Solution Approach 1:
The patent applies parameter changes by allowing flexible configuration of AI/ML model parameters through associated ID groups. The system can adjust model complexity, activation conditions, and other parameters at the group level, enabling complex problem-solving capabilities while managing configuration overhead through centralized group management rather than individual cell configuration.
Data Source
AI summary
A wireless transceiver/receiver unit (WTRU) comprises a processor configured to receive configuration information. The configuration information may include a plurality of associated identification (ID) groups, one or more associated identifiers (IDs) associated with each associated ID group of the plurality of associated ID groups, and/or a plurality sets of radio resource control (RRC) configurations, where each set of RRC configurations is associated with an associated ID. The processor may be configured to receive indication that an associated ID group of the plurality of associated ID groups is associated with one or more cells, activate a first cell using a first set of RRC configurations of the plurality of sets of RRC configurations, receive an activation message to activate a second cell, and perform an activation procedure.
