Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Ambient power devices, including passive and active types, increase radio resource utilization interference and latency in wireless networks, causing collisions and reducing network efficiency due to uncoordinated uplink transmissions and lack of processing capabilities.
Innovation Solution
A system and method for scheduling transmissions from ambient power devices using a transmission scheduling logic that detects devices, assigns frequencies and time slots, generates control frames with encoded identification and padding bits, and organizes devices into zones to integrate them into the network, minimizing collisions and optimizing resource utilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If ambient power devices transmit uplink data without coordination, then device simplicity is maintained, but radio resource utilization deteriorates due to collisions and interference
Solution Approach 1:
The patent introduces a coordinator device as an intermediary between ambient power devices and the wireless network. The coordinator collects information from ambient power devices and manages transmission scheduling, allowing simple uncoordinated devices to operate while preventing radio resource collisions and interference through centralized coordination.
2Area of stationary object
If the number of ambient power devices increases, then network coverage is expanded, but network efficiency deteriorates due to increased contention and latency
Solution Approach 1:
The patent divides the network into zones with multiple coordinators, each responsible for managing ambient power devices in their respective zones. This segmentation allows scalable network coverage expansion while maintaining efficient local coordination, preventing global contention issues and reducing latency through distributed zone-based management.
3Productivity
If existing transmission scheduling techniques are modified to manage ambient power devices, then network efficiency improves, but system complexity increases due to required network modifications
Solution Approach 1:
The patent uses a coordinator device as an intermediary that handles the complex scheduling and coordination functions, shielding the ambient power devices from system complexity. The coordinator implements modified transmission scheduling techniques to manage network efficiency while maintaining simple device architecture through the intermediary coordination layer.

AI summary
Devices, networks, systems, methods, and processes for scheduling transmissions from a plurality of ambient power devices are described herein. An Access Point (AP) can detect one or more ambient power devices and retrieve one or more device identifiers associated with the one or more ambient power devices. The AP can determine one or more transmission durations associated with the one or more ambient power devices. The AP may generate at least one control frame based on the one or more device identifiers and the one or more transmission durations. In that, the AP can insert, based on the one or more transmission durations, one or more padding bits in the at least one control frame to charge or trigger the one or more ambient power devices. The AP can coordinate with a relay or a wireless device to schedule uplink transmissions from the one or more ambient power devices.
