Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If backscatter communication devices use simple signal reflection to reduce power consumption and costs, then energy efficiency and device cost are improved, but channel measurement capability is lost leading to poor communication reliability
Solution Approach 1:
The patent introduces a terminal device as an intermediary that performs channel measurement on behalf of the backscatter communication device. The terminal device measures the channel quality between the network side device and the backscatter device, and reports the measurement results to the network side device, enabling reliable communication without requiring the backscatter device to have complex measurement capabilities
Solution Approach 2:
The terminal device performs multiple functions: it acts as both a communication device and a measurement device for the backscatter communication system. By utilizing the terminal's existing measurement capabilities, the system avoids adding complexity to the power-constrained backscatter device while still achieving accurate channel quality assessment
2Device complexity
If backscatter communication devices lack channel measurement capability to maintain simplicity, then device complexity is reduced, but channel quality uncertainty causes poor communication reliability
Solution Approach 1:
The terminal device serves as an intermediary that performs channel measurement on behalf of the backscatter communication device. The terminal device measures the channel quality between the network side device and the backscatter device, and reports the measurement results to the network side device, enabling reliable communication without requiring the backscatter device to have complex measurement capabilities
Solution Approach 2:
The terminal device autonomously performs channel measurement and reporting functions that would otherwise require the backscatter device to具备 measurement capabilities. The network side device configures the terminal with measurement parameters and reporting requirements, and the terminal independently executes these tasks, freeing the backscatter device from complexity while ensuring reliable communication
