Solution Overview
Problem
Existing wireless communication systems for AIoT devices face inefficiencies due to variable-length identifier transmissions, lack of security protection, and limited resource availability, leading to increased ON time, bandwidth usage, and energy demands, which hinder large-scale deployments.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If variable-length identifier transmissions are used in existing wireless communication systems, then device identification capability is maintained, but signaling overhead and bandwidth usage increase
Solution Approach 1:
The patent segments device identifiers into multiple parts: a shortened identifier for initial communication and resource allocation, and a full identifier for complete device identification. This segmentation allows the system to use only the necessary portion of the identifier in each communication phase, reducing overall signaling overhead while maintaining complete device identification capability when needed.
Solution Approach 2:
The patent applies partial action by transmitting only a portion of the device identifier (the shortened version) in initial communication phases such as random access and resource allocation. The full identifier is transmitted only when absolutely necessary, reducing bandwidth usage and signaling overhead while maintaining the ability to perform complete device identification when required.
2Use of energy by moving object
If full device identifiers are transmitted in all messages, then device identification accuracy is ensured, but energy consumption and ON time increase
Solution Approach 1:
The patent divides device identification into two stages: initial communication using shortened identifiers for low-power operation, and detailed communication using full identifiers when precision is required. This allows AIoT devices to operate in low-power mode for routine communications while maintaining the capability for accurate device identification when needed.
Solution Approach 2:
The patent transmits only the necessary portion of the device identifier in each communication phase. Shortened identifiers are used for initial access and resource allocation where full identification accuracy is not critical, reducing transmission energy. Full identifiers are transmitted only when complete device identification is required, optimizing the balance between energy consumption and identification accuracy.
3Productivity
If shortened device identifiers are used, then signaling overhead and power consumption are reduced, but device identification completeness may be compromised
Solution Approach 1:
The patent segments device identifier transmission into multiple phases: shortened identifiers are used in initial communication phases (random access, resource allocation) to improve spectral efficiency, while full identifiers are transmitted in subsequent phases when complete device information is required. This segmentation ensures that no device identifier information is permanently lost, only deferred to appropriate communication phases.
Solution Approach 2:
The patent performs preliminary communication using shortened device identifiers to establish connections and allocate resources before transmitting full device identifiers. This preliminary action improves spectral efficiency by reducing initial signaling overhead, while ensuring that complete device identifier information is transmitted beforehand to prevent any information loss for subsequent communications.
