Backscatter Terminal Feedback for Dynamic Channel Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In backscatter communication scenarios, dynamic changes in the number of backscatter devices and uncertain channel states can lead to misdetection or missed detection of communication channels or signals, reducing communication efficiency and reliability.
Innovation Solution
A method and apparatus for information transmission in backscatter communication, where a terminal sends first information to a network side device for configuration update and/or transmission adjustment. The first information includes inventory-related information, backscattering information, or information related to a carrier wave and/or control command.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the number of backscatter devices changes dynamically and channel state is uncertain, then the system can adapt to various scenarios, but misdetection or missed detection of communication channels or signals occurs, reducing communication efficiency and reliability
Solution Approach 1:
The patent implements a feedback mechanism where the terminal device sends first information (including detection results, inventory-related information, or backscattering information) to the network side device. The network side device uses this feedback to perform configuration updates and transmission adjustments, thereby resolving detection errors and improving communication reliability while maintaining adaptability to dynamic conditions
Solution Approach 2:
The patent performs preliminary detection and reporting actions before actual communication occurs. The terminal device detects channel conditions and device states in advance, sends this information to the network side device, which then performs preliminary configuration updates. This preliminary action prevents misdetection and missed detection during actual communication, resolving the contradiction between adaptability and reliability
2Reliability
If configuration updates and transmission adjustments are performed frequently to maintain reliability, then communication reliability improves, but system complexity and processing overhead increase
Solution Approach 1:
The patent implements partial configuration updates by selectively sending only necessary first information (detection results, inventory-related information, or backscattering information) from the terminal device to the network side device. This partial action approach maintains communication reliability by updating only what is needed, rather than performing complete frequent updates, thereby reducing system complexity and processing overhead
