Solution Overview
Problem
Content providers face challenges in transmitting data to multiple devices with varying network conditions and device capabilities, often necessitating a compromise in quality and capacity to accommodate the lowest quality connection, leading to inefficient resource utilization.
Innovation Solution
A system that manages and leverages capability profiles for devices to select an optimal set of subcarriers for data transmission, minimizing capacity loss and resource waste by aligning transmission parameters with the devices' capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If data transmission is optimized for the device with the lowest quality connection, then all devices can receive data, but transmission quality and capacity are sacrificed
Solution Approach 1:
The patent segments the data transmission by dividing available subcarriers into different groups based on device capability profiles. Each device receives data on subcarriers optimized for its specific capabilities, allowing simultaneous optimization for multiple devices rather than forcing a single transmission quality level for all.
Solution Approach 2:
The patent applies local quality by assigning different transmission parameters (modulation levels, subcarrier allocations) to different devices based on their individual capability profiles. This allows each device to receive data at the highest possible quality for its specific capabilities rather than using a uniform transmission quality for all devices.
2Productivity
If different transmission qualities are used for different devices, then transmission capacity is optimized, but resource management complexity increases
Solution Approach 1:
The patent creates a universal capability profile framework that can be applied to any device in the network. The system maintains a library of capability profiles that can be matched to devices based on their characteristics, providing a standardized approach to managing diverse device capabilities without requiring custom solutions for each device type.
Solution Approach 2:
The patent manages complexity by systematically varying transmission parameters (modulation levels, subcarrier assignments, code rates) based on device capability profiles. This structured parameter adjustment allows the system to optimize for different device types using a consistent methodology rather than requiring complex ad-hoc decision-making for each transmission.
3Productivity
If capability profiles are managed dynamically, then transmission optimization is improved, but system complexity and processing requirements increase
Solution Approach 1:
The patent performs preliminary action by pre-establishing capability profiles that characterize different device types and their transmission capabilities. These profiles are created and stored in advance, allowing the system to quickly match devices to appropriate transmission parameters without requiring complex real-time analysis of each device's capabilities during data transmission.
