Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If a digitally controlled surface with reflective elements is used to enhance transmission power and modify transmission direction, then transmission power and directionality are improved, but device complexity increases due to the need for control frame structures, dedicated physical control channels, sequences, and on-off patterns
Solution Approach 1:
The control information transmission is segmented into multiple components: synchronization signals, control frames with specific structures, dedicated physical control channels, sequences, and on-off patterns. This segmentation allows each component to serve a specific function in managing the digitally controlled surface while collectively solving the complexity issue through modular design
Solution Approach 2:
A dedicated physical control channel acts as an intermediary between the network device and the digitally controlled surface, carrying control information that guides the reflective elements. This intermediary mechanism simplifies the overall system by providing a dedicated pathway for control signals, separating control functions from data transmission functions
2Measurement precision
If control information is transmitted using dedicated physical control channels, sequences, and on-off patterns, then control precision is improved, but loss of time increases due to the additional overhead required for synchronization and control signaling
Solution Approach 1:
Synchronization signals are transmitted before the actual control information to establish timing references and synchronize the receiver. This preliminary action ensures that subsequent control information can be decoded accurately and timely, reducing errors while managing the time overhead through efficient synchronization protocols
Solution Approach 2:
Control information is transmitted using periodic patterns and sequences that can be detected and synchronized. The on-off patterns and sequential transmissions are organized in periodic frames that allow the receiver to anticipate and efficiently process control information, reducing the effective time loss through predictable timing structures
