UE Capability Coordination in Dual-Connection Hardware Conflicts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
User equipment (UE) experiences temporary capability restrictions when operating in dual-active state with multiple networks, leading to hardware conflicts and inefficient resource allocation, particularly in scenarios involving Multi-SIM or Multi-USIM devices.
Innovation Solution
The UE coordinates temporary capability restrictions by sending assistance information to networks, indicating allowed, affected, or forbidden band combinations and feature sets, along with specific parameter limitations, to manage resource sharing among multiple SIMs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If UE operates in dual-active state with multiple networks, then connectivity and communication versatility are improved, but hardware resources conflict and capability restrictions occur
Solution Approach 1:
The patent segments UE capabilities into different dimensions (band combinations, feature sets, parameter limitations) and reports them separately through UE assistance information. This allows the network to manage multiple connections by processing capability restrictions dimension by dimension, resolving hardware conflicts while maintaining dual-active connectivity.
Solution Approach 2:
The patent introduces UE assistance information as an intermediary mechanism between the UE and the network. This information structure mediates the capability restriction problem by providing a standardized way for the UE to communicate its temporary capability restrictions to the network, enabling coordinated resource allocation without direct hardware conflicts.
2Productivity
If UE reports temporary capability restriction to network, then resource allocation efficiency is improved, but communication overhead increases
Solution Approach 1:
The patent applies local quality by reporting capability restrictions at specific local dimensions (particular band combinations, specific feature sets, individual parameter limitations) rather than providing a complete capability reevaluation. This targeted approach improves resource allocation efficiency for affected areas while minimizing overall communication overhead.
Solution Approach 2:
The patent implements partial action by reporting only the necessary capability restriction information needed for resource allocation, rather than transmitting complete capability datasets. The UE assistance information includes only the temporary capability restrictions relevant to current network conditions, reducing overhead while maintaining allocation efficiency.
3Use of energy by moving object
If UE dynamically splits capabilities between SIMs, then hardware resource utilization is improved, but capability coordination complexity increases
Solution Approach 1:
The patent implements dynamics by enabling UE to dynamically report temporary capability restrictions when entering dual-active state, rather than having static capability configurations. The UE assistance information mechanism allows capabilities to be dynamically adjusted and reported based on current operational state, improving hardware utilization while managing coordination complexity through standardized reporting procedures.
