Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If separate measurements are conducted for each sectorization realization, then measurement precision is improved, but measurement time and productivity deteriorate
Solution Approach 1:
The patent combines multiple sectorization scheme measurements into a single measurement campaign by having different sectors transmit their reference signals simultaneously on different frequency layers. This merging approach maintains measurement precision while dramatically improving productivity by eliminating the need for separate measurement campaigns for each sectorization scheme.
Solution Approach 2:
The patent introduces a frequency dimension by assigning different frequency layers to different sectors for simultaneous transmission. This dimensional expansion allows multiple sectorization schemes to be measured concurrently without interfering with each other, resolving the contradiction between measurement precision and productivity.
2Measurement precision
If hardware changes are made for hard sectorization measurements, then measurement precision is improved, but device complexity and ease of manufacture deteriorate
Solution Approach 1:
The patent makes the base station capable of measuring multiple sectorization schemes without hardware changes by using software-configurable reference signal assignments. The same hardware infrastructure can now serve multiple measurement purposes through flexible resource allocation, reducing device complexity while maintaining measurement precision.
Solution Approach 2:
The patent changes the configurable parameters of the system (reference signal frequency layers, time slots) to accommodate different sectorization schemes without physical hardware modifications. This parameter-based flexibility allows the system to adapt to different measurement requirements while maintaining the same hardware setup.
3Productivity
If multiple sectors transmit reference signals simultaneously on the same frequency, then productivity is improved, but measurement precision deteriorates due to interference
Solution Approach 1:
The patent resolves the interference problem by moving transmissions to different frequency layers, effectively using the frequency dimension to separate simultaneous transmissions. This allows multiple sectors to transmit reference signals at the same time without mutual interference, maintaining both productivity and measurement precision.
