Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional positioning methods are used without utilizing antenna element associations, then the system is simpler to implement, but positioning accuracy and signal reception quality deteriorate
Solution Approach 1:
The system pre-establishes association relationships between antenna elements and reception beams before actual positioning operations. The base station configures and stores the correspondence between antenna element indices and reception beam indices in advance, so that when positioning is needed, the UE can directly utilize these pre-configured associations without performing complex real-time calculations, thus improving positioning accuracy while maintaining reasonable system complexity
Solution Approach 2:
Reception beams serve as an intermediary layer between antenna elements and positioning measurements. Instead of directly using antenna element indices for positioning, the system introduces reception beams as a mediator that maps antenna element associations to positioning-relevant parameters, enabling improved positioning accuracy through beam-formed signals while managing system complexity through this intermediate abstraction layer
2Measurement precision
If detailed capability information about antenna elements and reception beams is transmitted, then positioning accuracy improves, but signaling overhead increases
Solution Approach 1:
The system extracts and transmits only the essential capability information needed for positioning - specifically the association relationship between antenna elements and reception beams - rather than transmitting all possible parameters. By selecting and transmitting only the most critical information (antenna element indices, reception beam indices, and their associations), the system achieves improved positioning accuracy while minimizing signaling overhead by excluding redundant data
Solution Approach 2:
The system changes the parameter representation from transmitting detailed individual antenna element characteristics to transmitting compact association indices. Instead of sending full parameter sets for each antenna element, the system uses index-based representation where capability information includes only the essential mapping relationships, reducing the volume of transmitted data while preserving positioning accuracy through efficient parameter encoding
3Reliability
If multiple reception beams are configured and managed, then signal reception quality improves, but device complexity increases
Solution Approach 1:
The system segments the complex task of managing multiple reception beams by dividing it into distinct manageable components: antenna element configuration, reception beam configuration, and their association relationships. Each component is handled separately with dedicated indexing and reporting mechanisms, allowing the system to manage multiple beams for improved signal reception quality while reducing overall complexity through modular organization of beam management functions
