Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If bandwidth aggregation of positioning reference signals is implemented, then positioning accuracy is improved, but system complexity increases
Solution Approach 1:
The patent segments the bandwidth aggregation configuration into multiple independent components: indication information for bandwidth aggregation capability, assistance information for terminal capabilities, and separate configuration parameters for multiple frequency bands and carriers. This segmentation allows the complex bandwidth aggregation function to be managed through modular, independent configuration elements, reducing overall system complexity while maintaining positioning accuracy improvements.
Solution Approach 2:
The patent implements preliminary action by having the terminal pre-send assistance information about its bandwidth aggregation capabilities to the core network device before actual positioning operations. The core network device then pre-generates and sends indication information about available bandwidth aggregation configurations. This preliminary exchange of capability and configuration information allows the system to be optimized in advance, reducing real-time complexity during positioning operations.
2Productivity
If bandwidth aggregation configuration is optimized for positioning, then resource utilization improves, but communication overhead increases
Solution Approach 1:
The patent extracts bandwidth aggregation capability information and terminal assistance information as separate, standalone data elements that can be independently configured and transmitted. By extracting these capability indicators from the main positioning protocol, the system can efficiently manage resource utilization through dedicated capability exchange messages, reducing the overhead embedded in core positioning operations while maintaining optimized resource allocation.
Solution Approach 2:
The patent utilizes parameter changes by dynamically adjusting bandwidth aggregation configurations based on terminal capabilities and network conditions. The indication information and assistance information enable flexible parameter modification for different frequency bands and carriers, allowing the system to optimize resource utilization by activating bandwidth aggregation only when and where needed, thereby minimizing unnecessary communication overhead while maintaining high resource efficiency.
