Ambient IoT Backscattering Service Backup via Sidelink
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
As the number of IoT devices is expected to surge, existing wireless communication technologies face challenges in efficiently managing and providing backscattering services to ambient IoT devices, which are energy-harvesting and often require precise resource allocation and authentication, leading to inefficiencies and potential service disruptions.
Innovation Solution
A processor-implemented method and apparatus that enable user equipment (UE) to provide backscattering services to ambient IoT devices by selecting and managing a serving UE and backup UEs through sidelink communication, allowing for dynamic service period management and resource allocation, including the ability to cease or reassign services as needed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If backup UE mechanism is implemented, then service continuity is improved, but system complexity increases
Solution Approach 1:
The system pre-configures backup UEs and establishes backup procedures before service disruption occurs. The network device selects and configures backup UEs in advance, so when the serving UE becomes unavailable, the backup UE can immediately take over without requiring real-time search and selection processes, thus improving service continuity while managing complexity through advance preparation.
Solution Approach 2:
The network device acts as an intermediary that manages the backup UE mechanism. It selects serving UEs, configures backup procedures, and coordinates handovers between serving and backup UEs. This centralised management approach simplifies the overall system by having a dedicated controller handle the complexity of backup coordination.
2Productivity
If dynamic service period management is implemented, then resource allocation efficiency is improved, but control complexity increases
Solution Approach 1:
The system implements dynamic service period management where the network device can adjust the service duration and allocation based on real-time conditions. The service period parameter is made variable, allowing the system to adapt to changing network conditions, device availability, and service requirements, thereby improving resource allocation efficiency through flexible temporal management.

AI summary
A user equipment apparatus includes at least one processor and at least one memory. The at least one memory stores instructions which, when executed by the at least one processor, cause the user equipment apparatus at least to: receive, from a network device, an instruction to provide backscattering service to at least one ambient IoT device for a service period of time T, the instruction including a configuration for sidelink communication with one or more backup user equipment apparatuses (backup UEs) capable of providing backscattering service to at least one ambient IoT device; and provide, based on the instruction, the backscattering service by transmitting at least one request for tag identification.
