Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If user equipment connects to multiple network nodes simultaneously in dual-active state, then communication reliability and service continuity are improved, but network coordination complexity and resource management difficulty increase
Solution Approach 1:
The patent segments the coordination functions into distinct types: band combination coordination, power control coordination, capability coordination, and measurement coordination. Each coordination type is handled through separate information elements and procedures, dividing the complex multi-network coordination task into manageable segments that can be processed independently while maintaining overall system reliability.
Solution Approach 2:
The patent introduces an intermediary coordination mechanism where the UE acts as a mediator between multiple network nodes. The UE receives coordination information from one network node and applies it to coordinate with other network nodes, facilitating seamless dual-active operations without requiring direct complex interactions between all network nodes.
2Productivity
If user equipment coordinates multiple networks with comprehensive capability information, then resource allocation efficiency is improved, but information management overhead and signaling complexity increase
Solution Approach 1:
The patent implements preliminary action by having the UE determine and store its band combination capabilities, power control capabilities, and measurement capabilities in advance. This pre-determined capability information is then efficiently communicated to network nodes through standardized information elements, reducing real-time signaling overhead while enabling rapid resource allocation decisions.
Solution Approach 2:
The patent utilizes parameter changes by encoding capability information in structured information elements with specific parameters such as band combination lists, power control parameter sets, and measurement configuration parameters. This structured parameter approach allows efficient transmission and interpretation of capability information without excessive signaling overhead.
3Reliability
If comprehensive capability coordination is implemented for dual-active state, then communication performance is improved, but system complexity and configuration overhead increase
Solution Approach 1:
The patent segments capability coordination into four distinct coordination types: band combination coordination, power control coordination, capability coordination, and measurement coordination. Each type is handled through dedicated information elements and procedures, making the overall system more manageable despite the comprehensive nature of the coordination requirements.
Solution Approach 2:
The patent implements universal coordination mechanisms that can be applied across different network nodes and scenarios. The same coordination frameworks and information element structures are used whether coordinating with two networks or multiple networks, reducing the need for scenario-specific complexity while maintaining comprehensive coordination capabilities.
