Engineering Contradiction Analysis
1Length of stationary object
If beamforming and MIMO techniques are introduced to increase propagation distance in 5G systems, then propagation loss is mitigated and coverage is extended, but device complexity and positioning accuracy deteriorate due to the complexity of these techniques
Solution Approach 1:
The patent segments the positioning assistance data into multiple parts: cell identity information, beamforming configuration parameters, and MIMO-related positioning data. This segmentation allows the terminal to process positioning information in a structured manner, reducing the complexity burden while maintaining positioning accuracy in beamforming and MIMO environments.
Solution Approach 2:
The patent introduces positioning assistance data as an intermediary that mediates between the complex beamforming/MIMO systems and the terminal positioning function. This intermediary contains pre-processed positioning-relevant information that simplifies the terminal's positioning task while enabling accurate positioning in advanced 5G communication environments.
2Measurement precision
If positioning assistance data is acquired through existing methods, then positioning function is implemented, but positioning precision and time efficiency worsen due to lack of targeted assistance data acquisition
Solution Approach 1:
The patent applies preliminary action by having the network pre-generate and provide positioning assistance data containing cell identity information, beamforming parameters, and MIMO configuration data before the terminal needs to perform positioning. This pre-prepared data enables the terminal to quickly acquire positioning information without time-consuming processing, thereby improving both positioning speed and precision.
Solution Approach 2:
The terminal uses the acquired positioning assistance data to independently determine its position without requiring complex real-time interactions with the network. The self-service mechanism allows the terminal to efficiently process the pre-provided assistance data and complete positioning operations autonomously, reducing time loss while maintaining high precision.
