Engineering Contradiction Analysis
1Illumination intensity
If beamforming techniques are used in high frequency 5G scenarios, then signal directionality and coverage are improved, but link stability deteriorates due to high penetration loss and diffraction causing beam blockage
Solution Approach 1:
The patent implements dynamic beam configuration where the base station determines beam transmission schemes based on real-time UE performance feedback. The system dynamically adjusts beam parameters including beam width, beam direction, and beam forming factors according to channel conditions, allowing the beamforming system to adapt to changing environmental conditions and maintain link stability despite blockage-prone high-frequency propagation
Solution Approach 2:
The system changes key beamforming parameters including beam width, beam direction, and beam forming factors based on UE performance metrics such as reception quality and blockage detection. By adjusting these parameters dynamically, the system optimizes signal transmission to overcome penetration loss and diffraction effects while maintaining reliable communication links
2Reliability
If multiple beams are used for transmission and reception, then signal robustness is improved, but system complexity increases due to beam configuration and management
Solution Approach 1:
The patent implements a self-configuring beam system where the UE autonomously measures beam quality metrics and provides performance feedback to the base station. The base station then automatically determines the appropriate beam transmission scheme based on this feedback, eliminating the need for complex manual beam configuration and reducing system complexity while maintaining multiple beam transmission for robustness
Solution Approach 2:
The system establishes a feedback loop where the UE reports beam reception quality and performance metrics to the base station. The base station uses this feedback to automatically adjust beam configuration parameters and select optimal beam pairs, simplifying the overall system complexity while maintaining reliable multi-beam transmission through intelligent adaptive control
3Manufacturing precision
If beam transmission scheme is customized according to UE performance, then transmission quality is improved, but signaling overhead increases due to performance reporting
Solution Approach 1:
The patent implements selective performance reporting where the UE reports only critical beam-related performance metrics necessary for beam configuration decisions. The base station requests specific performance information relevant to beam selection and configuration, reducing unnecessary signaling overhead while maintaining sufficient precision for optimizing beam transmission schemes
