Engineering Contradiction Analysis
1Adaptability or versatility
If existing wireless communication systems use conventional reference signal configurations, then the system structure is simple, but the flexibility in time and frequency domain patterns is limited
Solution Approach 1:
The patent segments the reference signal configuration into distinct components: time domain pattern parameters (including multiple time domain patterns that can be combined), frequency domain pattern parameters, and sequence generation parameters. This segmentation allows each component to be independently configured and optimized, providing flexibility while maintaining manageable complexity through structured parameter organization.
Solution Approach 2:
The patent implements dynamic configuration capabilities where the reference signal parameters can be adjusted based on different sensing scenarios. The system can dynamically select from multiple time domain patterns, adjust frequency domain allocations, and modify sequence generation parameters to adapt to varying radar sensing requirements, enabling the system to optimize performance for different applications.
2Adaptability or versatility
If the sensing reference signal uses fixed pattern parameters, then the configuration is simple, but the multiplexing options are limited
Solution Approach 1:
The patent designs a universal configuration framework that can support multiple sensing scenarios through a single unified parameter structure. The time domain pattern parameters, frequency domain parameters, and sequence generation parameters work together to enable the same reference signal configuration to serve multiple sensing functions, including different radar applications, thereby providing multiplexing capabilities without requiring separate dedicated configurations for each scenario.
Solution Approach 2:
The patent utilizes parameter changes to enable multiplexing by allowing dynamic adjustment of time domain pattern indices, frequency domain allocation parameters, and sequence generation parameters. By changing these parameters, the system can multiplex different sensing references signals in time, frequency, or code domains, providing multiple multiplexing options while maintaining a consistent and manageable configuration structure.
3Adaptability or versatility
If the reference signal sequence is generated with fixed parameters, then the generation process is simple, but radar-specific sequence adjustments are limited
Solution Approach 1:
The patent implements a sequence generation mechanism that accepts radar-specific parameters as input, allowing the base sequence to be modified according to specific radar applications. The sequence generation parameters include adjustments for radar waveform characteristics, such as pulse repetition intervals, bandwidth allocations, and waveform shaping parameters. This enables radar-specific sequence adjustments by changing generation parameters while maintaining a systematic approach that prevents excessive complexity through structured parameter organization.
