Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If beamforming and multiple TRPs are used to improve reliability, then communication reliability is improved, but device complexity increases
Solution Approach 1:
The patent segments the reference signal transmission by associating different transmission schemes (first and second schemes) with different time intervals. This allows the system to handle multiple TRPs and beamforming configurations separately in different time periods, reducing the overall complexity while maintaining reliability through diverse transmission paths.
Solution Approach 2:
The patent introduces dynamic switching between different transmission schemes based on time intervals and channel conditions. The wireless device can adaptively change transmission parameters (such as beamforming configurations and reference signal structures) according to varying channel states, maintaining optimal reliability without requiring complex static configurations for all possible scenarios.
2Adaptability or versatility
If multiple transmission schemes are used to handle dynamic scenarios, then adaptability is improved, but device complexity increases
Solution Approach 1:
The patent implements periodic switching between different transmission schemes across defined time intervals. By organizing transmissions into periodic patterns with distinct schemes for different intervals, the system achieves high adaptability to changing conditions while following a manageable periodic structure rather than requiring complex real-time decision-making for every transmission.
Solution Approach 2:
The patent changes key transmission parameters (such as reference signal structures, beamforming configurations, and transmission schemes) based on time intervals and channel conditions. This allows the system to adapt to diverse scenarios by modifying specific parameters rather than redesigning the entire transmission system, maintaining versatility with controlled complexity.
3Measurement precision
If reference signaling is transmitted over extended time intervals to improve measurement accuracy, then measurement precision is improved, but loss of time increases
Solution Approach 1:
The patent extracts and separates reference signal transmissions into specific, dedicated time intervals distinct from data transmission. By allocating particular time resources exclusively for reference signaling with appropriate schemes, the system achieves sufficient measurement precision without extending the overall communication time, as reference signals are efficiently packed into designated slots rather than spread throughout the entire transmission period.
