Conditional L1 Measurement Configuration for 5G Cell Activation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication systems face inefficiencies in managing measurement and reporting configurations for target cells, leading to suboptimal resource allocation and increased signaling latency during intra-DU and inter-DU serving cell changes in 5G networks.
Innovation Solution
Implementing a mechanism where user equipment (UE) receives L1 measurement and reporting configurations for target cells, which are dormant and activated based on explicit or implicit conditions, allowing for optimized measurement and reporting only when necessary, reducing unnecessary resource reservation and signaling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If measurement and reporting configurations are continuously maintained for target cells, then measurement readiness is improved, but resource consumption and signaling overhead increase
Solution Approach 1:
The patent applies dynamics by transitioning from static continuous maintenance to dynamic conditional activation. Measurement and reporting configurations are activated only when specific conditions are met (such as handover requirements), allowing the system to adapt its state based on operational needs rather than maintaining constant readiness regardless of context.
Solution Approach 2:
The patent implements preliminary action by pre-configuring measurement and reporting parameters in advance, but keeping them in a dormant or inactive state until activation conditions are satisfied. This allows the system to prepare measurement capabilities beforehand while avoiding unnecessary resource consumption during periods when measurements are not required.
2Speed
If measurement configurations are activated immediately upon receipt, then measurement speed is improved, but unnecessary signaling and resource reservation increase
Solution Approach 1:
The system dynamically adjusts the activation timing of measurement configurations based on operational context. Rather than immediate activation, the system waits for specific triggering conditions to be met, thereby avoiding premature signaling and resource reservation while maintaining the ability to activate measurements quickly when needed.
Solution Approach 2:
The patent implements periodic or event-driven activation rather than continuous operation. Measurement configurations are activated at specific intervals or upon occurrence of triggering events (such as handover decisions), allowing the system to balance measurement speed requirements with unnecessary signaling reduction.
3Adaptability or versatility
If all target cells are configured for measurement and reporting, then measurement coverage is improved, but system complexity and signaling overhead increase
Solution Approach 1:
The patent segments the set of target cells into different categories or groups based on their measurement requirements. Instead of uniformly configuring all target cells, the system divides them into those that require active measurement configurations versus those that can remain in a dormant state, thereby reducing overall system complexity while maintaining adequate measurement coverage for relevant cells.
Solution Approach 2:
The patent applies local quality by tailoring measurement configuration activation to individual cell characteristics and operational contexts. Rather than applying a uniform configuration approach to all target cells, the system adjusts the activation state and measurement parameters based on local conditions such as cell type, signal strength, and handover probability, thereby reducing unnecessary complexity.

AI summary
An apparatus configured to: receive a first measurement and reporting configuration for at least one first cell of an active set and a second measurement and reporting configuration for at least one second cell of a configured set, wherein the at least one second cell is a target cell and not part of the active set; measure and report the at least one first cell based on the first measurement and reporting configuration; abstain from measuring and reporting the at least one second cell based on the second measurement and reporting configuration; send an indication that an activation condition is met for the at least one second cell; add the at least one second cell to the active set based on a confirmation indication; and measure and report the at least one second cell based on the second measurement and reporting configuration.
