Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional beam reporting methods are used without differentiation between SFN and non-SFN beams, then the system maintains simplicity in measurement and reporting procedures, but the ability to utilize SFN network functions for higher throughput and reliability is limited
Solution Approach 1:
The patent applies local quality by introducing beam preference settings that allow different beam types (SFN and non-SFN) to be treated differently. The network can configure specific beam preferences for different TRPs or beam groups, enabling differentiated measurement and reporting for SFN beams while maintaining conventional reporting for non-SFN beams. This localized differentiation enhances SFN utilization without requiring complete restructuring of the beam reporting framework.
Solution Approach 2:
The patent changes the parameter of beam measurement by introducing biasing factors that are applied differently based on beam type. SFN beams can have different biasing values applied to their measurement results compared to non-SFN beams, allowing the network to optimize beam selection for SFN scenarios. This parameter modification enables the system to leverage SFN capabilities for improved throughput and reliability while maintaining backward compatibility with existing beam reporting mechanisms.
2Measurement precision
If beam preference settings and biasing factors are applied to differentiate SFN and non-SFN beam reports, then beam reporting accuracy and selection are improved, but the complexity of measurement and reporting procedures increases
Solution Approach 1:
The patent implements preliminary action by pre-configuring beam preference settings and biasing factors before beam measurement and reporting occur. The network configures these parameters in advance based on the SFN deployment scenario, so that during actual beam reporting, the UE simply applies the pre-configured biasing factors to SFN beams. This preliminary configuration reduces real-time complexity while maintaining high measurement precision, as the differentiating logic is established beforehand rather than computed dynamically during measurement.
3Productivity
If differentiated measurement and reporting for SFN and non-SFN beams is implemented, then communication performance throughput and reliability are enhanced, but the processing overhead and signaling complexity increase
Solution Approach 1:
The patent applies universality by designing a beam reporting framework that can handle both SFN and non-SFN beams through a unified interface. The same measurement and reporting procedures are used for both beam types, with the differentiation achieved through configurable parameters rather than separate procedural paths. This multi-functional approach allows the system to enhance throughput for SFN scenarios while avoiding the need for separate signaling channels or procedures, thus minimizing additional signaling overhead.
