Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If elevation beamforming technique is utilized without a suitable configuration mechanism for the two-dimensional antenna array, then the radiation pattern can be controlled on vertical and horizontal domains, but the communication performance cannot be effectively improved
Solution Approach 1:
The patent segments the two-dimensional antenna array configuration into multiple independent antenna port formation patterns (APFPs), where each APFP corresponds to a specific dimension (horizontal or vertical). This segmentation allows the system to independently configure and optimize each dimension without complex interdependencies, enabling effective elevation beamforming while maintaining manageable configuration complexity.
Solution Approach 2:
The patent introduces dynamic configuration mechanisms that allow the antenna array to adaptively switch between different APFPs based on channel conditions and communication requirements. The system can dynamically adjust the antenna port formation patterns to optimize beamforming performance in different scenarios, making the configuration mechanism flexible rather than static and complex.
2Measurement precision
If multiple antenna port formation patterns are configured for different dimensions, then channel measurement precision is improved, but the configuration and management of antenna ports becomes more complex
Solution Approach 1:
The patent divides the antenna array into multiple independent APFPs, where each pattern is dedicated to measuring channel characteristics in a specific dimension. This segmentation allows the system to perform independent channel measurements for horizontal and vertical dimensions, improving measurement precision while keeping each measurement task simple and manageable rather than attempting to measure all dimensions simultaneously.
Solution Approach 2:
The patent introduces reference signals as intermediaries that facilitate channel measurement for each APFP. These reference signals are transmitted through specific antenna port formations and serve as mediators between the physical antenna array and the channel estimation process, simplifying the measurement mechanism while improving precision.
3Loss of information
If the antenna array is configured to transmit reference signals with multiple APFPs, then feedback overhead is reduced, but the transceiving and signal distribution circuits become more complex
Solution Approach 1:
The patent segments the reference signal transmission into multiple independent APFPs, where each pattern transmits reference signals for specific dimensional measurements. This segmentation allows the system to efficiently multiplex reference signals in different antenna port formations, reducing the overall feedback overhead by organizing measurements systematically rather than requiring comprehensive feedback for all possible configurations.
Solution Approach 2:
The patent designs the transceiving and radio signal distribution circuits to be multi-functional, capable of supporting multiple APFPs through a unified architecture. The circuits can dynamically reconfigure to support different antenna port formation patterns, providing universal functionality that reduces feedback overhead without requiring separate dedicated hardware for each pattern.
