Wireless Tag Capability Signaling for Adaptive Network Configuration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face challenges in effectively managing and configuring communication with ultra-low power and ultra-low cost wireless tags, such as ambient IoT devices, due to their unique capabilities and varied connection topologies, leading to inefficiencies and suboptimal communication configurations.
Innovation Solution
A communication control method where a communication node transmits capability information to a network node, indicating its ability to transmit to or receive from wireless tags, allowing the network node to appropriately configure communication settings based on the node's capabilities, including frequency information, topology support, and directionality, thereby enabling efficient communication with wireless tags.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If wireless communication systems use conventional communication configurations, then system complexity is reduced, but communication efficiency with wireless tags deteriorates
Solution Approach 1:
The patent introduces capability information parameters that indicate whether a communication node has transmission capability, reception capability, or both. By changing the parameter representation from binary (connected/not connected) to multi-state (transmission only, reception only, both), the system optimizes communication efficiency without significantly increasing complexity.
Solution Approach 2:
The communication capability is segmented into distinct functional components: transmission capability and reception capability. This segmentation allows the network to independently configure and optimize each capability type, improving overall communication efficiency while maintaining manageable system complexity through modular configuration.
2Adaptability or versatility
If the system supports varied connection topologies for wireless tags, then adaptability improves, but configuration complexity increases
Solution Approach 1:
The capability information mechanism serves multiple functions: it identifies transmission capability, reception capability, and by extension, different connection topologies. This universal approach allows the same signaling mechanism to support various topologies (one-to-one, one-to-many, many-to-one) without requiring separate configuration protocols, thereby improving adaptability while controlling complexity.
3Productivity
If capability information is transmitted for all communication nodes, then communication optimization improves, but signaling overhead increases
Solution Approach 1:
The patent applies capability information transmission selectively rather than universally. Capability information is transmitted only when needed for optimization, such as when establishing new connections or reconfiguring existing ones. This partial action approach achieves communication optimization benefits while minimizing unnecessary signaling overhead.
