Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing communication technologies are used, then terminal communication is supported, but ranging or positioning of a first terminal based on a second terminal within a designated terminal group is not supported
Solution Approach 1:
The patent segments the terminal group into different types (first terminal group and second terminal group) with distinct ranging or positioning capabilities. The network element selectively provides group discovery information based on the terminal group type, enabling ranging or positioning functionality only where needed without increasing overall system complexity.
Solution Approach 2:
The network element acts as an intermediary that receives ranging or positioning requests, determines the appropriate terminal group, and provides group discovery information to enable the first terminal to discover and use the second terminal for ranging or positioning. This mediator approach adds capability without requiring direct complexity increases between terminals.
2Measurement precision
If group discovery information is transmitted to enable ranging or positioning, then ranging or positioning accuracy is improved, but information transmission complexity increases
Solution Approach 1:
The network element performs preliminary action by pre-determining which terminals belong to which groups and preparing group discovery information in advance. This allows the first terminal to quickly discover the second terminal without requiring complex real-time information exchange, reducing overall information transmission overhead while maintaining positioning accuracy.
Solution Approach 2:
The group discovery information serves multiple functions: it identifies terminal group membership, enables the first terminal to discover the second terminal, and provides the basis for ranging or positioning calculations. This multi-functionality reduces the need for separate information transmissions, minimizing information loss while improving measurement precision.
