Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If traditional beam sweeping configuration is used, then system compatibility is maintained, but beam indication latency is high
Solution Approach 1:
The patent segments the beam sweeping process into multiple stages: capability reporting phase, configuration phase, and execution phase. By dividing the complex beam indication process into manageable segments with specific timing requirements, the system reduces overall latency while maintaining manageable complexity through standardized interfaces between segments.
Solution Approach 2:
The patent implements preliminary capability reporting by the UE before actual beam indication is needed. The UE reports its beam sweeping capabilities and preferences in advance, allowing the network to pre-configure appropriate parameters. This preliminary action eliminates the need for complex real-time negotiations during beam indication, significantly reducing latency.
2Measurement precision
If multiple beams are used for synchronization signal block measurements, then measurement accuracy is improved, but processing time increases
Solution Approach 1:
The patent implements periodic beam sweeping where the UE systematically measures multiple beams in a structured sequence rather than attempting all measurements simultaneously. The periodic action allows the UE to complete measurements across multiple beams within defined time intervals, improving accuracy while managing processing time through predictable measurement cycles.
Solution Approach 2:
The patent incorporates feedback mechanisms where the UE reports measurement results for different beams back to the network. Based on this feedback, the network can dynamically adjust which beams need further measurement and prioritize measurements that yield the most accurate results fastest, optimizing the balance between measurement precision and processing time.
3Manufacturing precision
If energy per resource element offset is determined for each beam, then beam alignment precision is improved, but computational complexity increases
Solution Approach 1:
The patent applies local quality by determining energy per resource element offsets individually for each beam based on its specific characteristics and measurement conditions. Each beam receives customized offset determination tailored to its local measurement results rather than applying a uniform approach, improving alignment precision while managing computational complexity through targeted processing.
Solution Approach 2:
The patent utilizes parameter changes by adjusting the offset determination methodology based on beam-specific parameters such as signal strength, interference levels, and measurement accuracy requirements. By changing the computational approach dynamically according to beam characteristics, the system achieves high precision alignment while optimizing computational resource usage.
