Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If separate beams are provided for data communication and positioning, then positioning accuracy is improved, but device complexity increases
Solution Approach 1:
The patent divides the beam management function into separate beams for data communication and positioning purposes. The base station transmits different reference signals (CSI-RS for data, PRS for positioning) through different beams, allowing independent optimization of each function without interference, thus improving positioning accuracy while managing complexity through functional separation.
Solution Approach 2:
The patent enables the wireless communication system to perform multiple functions using a unified framework. The same base station and user equipment infrastructure supports both data communication and positioning operations, with the ability to switch between different beam configurations and reference signals based on the required function, reducing overall system complexity despite the separation of functions.
2Measurement precision
If optimization of transmission and reception beams is performed for timing measurement, then measurement accuracy is improved, but use of energy increases
Solution Approach 1:
The patent performs beam optimization and selection in advance before actual timing measurement operations. The base station and user equipment pre-establish optimal beam pairs for positioning by exchanging reference signals and determining best beam directions, so that when actual positioning measurements are needed, the optimized beams are already in place, reducing real-time energy consumption while maintaining high measurement accuracy.
