Zero-Power Terminal Channel Selection for Reliable Signaling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Zero power terminals struggle to determine the appropriate channel for signal reception and transmission after obtaining power, leading to inefficiencies in power consumption and complexity in communication with network devices.
Innovation Solution
The terminal device and network device determine specific channels for signal reception and transmission using predefined rules and shifting amounts based on identifiers and system information, allowing for efficient power management and reduced complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the zero power terminal monitors signals on all channels to ensure reliable communication, then communication reliability is improved, but power consumption increases
Solution Approach 1:
The patent divides the communication channels into multiple segments and assigns each terminal a specific subset of channels to monitor based on its identifier. This segmentation allows terminals to focus their monitoring efforts on fewer channels, reducing power consumption while maintaining communication reliability through distributed channel coverage across the network.
2Adaptability or versatility
If the zero power terminal transmits signals on all channels to ensure network coverage, then adaptability is improved, but device complexity increases
Solution Approach 1:
The patent applies local quality by making different terminals have different channel monitoring and transmission responsibilities based on their identifiers. Each terminal is configured with specific channel(s) that it should monitor and/or transmit on, creating a differentiated local configuration that collectively provides full channel coverage without requiring any single terminal to handle all channels.
