Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in efficiently managing the addition and change of primary secondary cell configurations in next-generation networks, particularly in 5G systems, where dynamic resource allocation and signal quality optimization are crucial for user equipment (UE) connectivity.
Innovation Solution
The method involves obtaining a secondary cell group configuration and associated information from a target secondary node, modifying the master cell group configuration based on this information, and transmitting a conditional primary secondary cell addition or change configuration to the user equipment, ensuring optimal cell selection and resource allocation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conditional PSCell addition/change configuration is implemented to enable dynamic cell management, then resource utilization and signal quality are improved, but system complexity and configuration management difficulty increase
Solution Approach 1:
The patent applies preliminary action by pre-configuring conditional PSCell addition/change parameters and criteria before they are needed. The network node prepares configuration objects, execution conditions, and candidate cell information in advance, so that when signal quality requirements arise, the system can quickly activate pre-prepared configurations without complex real-time decision-making.
Solution Approach 2:
The configuration is segmented into distinct components: configuration objects containing PSCell parameters, execution conditions specifying when to apply configurations, and candidate cell information. This segmentation allows independent management and processing of each element, reducing overall configuration management complexity while enabling flexible combination based on signal quality requirements.
2Adaptability or versatility
If multiple configuration objects and execution conditions are maintained for different PSCell scenarios, then adaptability and resource allocation flexibility are improved, but information management complexity increases
Solution Approach 1:
The system implements feedback mechanisms where the network node monitors signal quality metrics and automatically selects appropriate configuration objects based on execution conditions. This feedback loop ensures that the correct configuration information is activated based on current network state, maintaining adaptability while managing information through automated decision rules rather than manual control.
Solution Approach 2:
Multiple configuration objects are prepared in advance with associated execution conditions, allowing the system to maintain adaptability for various PSCell scenarios without needing to manage complex real-time information. The pre-defined configuration sets include all necessary parameters and conditions, reducing the need for dynamic information processing.

AI summary
Aspects relate to wireless communication where a master node (MN) or a secondary node (SN) may initiate a conditional addition of a primary secondary cell (PSCell) or a conditional change from one PSCell to another PSCell. Each candidate target PSCell may provide information to be used by the MN to generate a conditional PSCell addition (CPA) configuration or a conditional PSCell change (CPC) configuration that is sent to a user equipment (UE). This information may indicate an execution condition for each candidate target PSCell and/or radio bearers that each candidate target PSCell supports or does not support. An MN may modify a master cell group (MCG) configuration for a PSCell based on information received from a target SN with an secondary cell group (SCG) configuration for the PSCell. The MN may transmit a CPA or CPC configuration including the modified MCG configuration and the SCG configuration to the UE.
