Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face challenges in efficiently coordinating user equipment (UE) capability, particularly in reporting maximum aggregated bandwidth and MIMO layer restrictions for multiple connection scenarios, leading to inefficiencies and performance issues.
Innovation Solution
The proposed solution involves methods and systems for coordinating UE capability by allowing network nodes to exchange UE aggregated capability information, including bandwidth and MIMO layer allowances, through messages between master and secondary network nodes, thereby optimizing resource allocation and reducing signaling overhead.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the UE reports detailed capability information for each band combination separately, then the network can accurately allocate resources, but the signaling overhead increases significantly
Solution Approach 1:
The patent combines capability reporting for multiple band combinations into a single aggregated message. Instead of reporting each band combination's capabilities separately, the UE aggregates the capability information and transmits it in one unified report, reducing the total signaling overhead while maintaining the ability to convey detailed capability data for resource allocation
Solution Approach 2:
The aggregated capability message serves multiple functions simultaneously: it provides capability information for multiple band combinations, enables resource allocation accuracy, and reduces signaling overhead. This multi-functional approach allows a single message structure to address several requirements that would otherwise require separate reporting mechanisms
2Productivity
If the network nodes coordinate UE capability information exchange, then resource allocation efficiency improves, but the system complexity increases
Solution Approach 1:
The patent introduces an intermediary aggregated capability message that facilitates coordination between master and secondary network nodes. This intermediary structure simplifies the coordination process by providing a standardized information exchange format, reducing the complexity of direct node-to-node coordination while improving resource allocation efficiency through systematic capability sharing
Solution Approach 2:
The patent changes the parameter representation from individual band combination details to aggregated capability parameters. By transforming the capability information into aggregated form with condensed parameters, the system reduces coordination complexity while maintaining the necessary information for efficient resource allocation across multiple band combinations
3Reliability
If the UE connects to multiple network nodes simultaneously, then network coverage and reliability improve, but the coordination of capability resources becomes more difficult
Solution Approach 1:
The patent segments the multi-connection capability coordination into manageable components through the aggregated message structure. By dividing the capability information into organized segments that can be systematically processed, the system enables reliable multi-node connections while reducing the coordination complexity that would arise from managing each connection independently

AI summary
The present disclosure describes methods, systems, and devices for coordinating user equipment (UE) capability. One method includes receiving, by a master network node from a user equipment (UE), UE aggregated capability information for at least one multi-connection band combination (BC); and sending, by the master network node to a secondary network node, a first message indicating a group of capability resources allowed for the secondary network node, wherein: the group of capability resources comprises at least one of the following: an aggregated bandwidth allowed for the secondary network node, or an aggregated MIMO layer allowed for the secondary network node.
