Wireless Resource Allocation for High-Efficiency Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless communication networks face inefficiencies due to device interference and congestion, particularly in high-density environments, where existing methods struggle to optimize resource allocation and communication modes effectively.
Innovation Solution
A processing system allocates resources, such as sub-bands of frequencies or subsets of data tones, to devices within a single uplink or downlink tone plan, using specific FFT sizes and tone plans to improve communication efficiency by optimizing bandwidth and tone allocation, allowing for concurrent operation of high-efficiency and legacy devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple devices share the same communication network resources, then network coverage and device connectivity are improved, but congestion and inefficient link usage occur
Solution Approach 1:
The communication network divides the available bandwidth into multiple subbands, and each device is assigned to specific subbands rather than sharing the entire bandwidth. This segmentation allows multiple devices to operate simultaneously on different frequency segments, improving both connectivity and efficiency by reducing interference and congestion on individual links.
2Productivity
If device transmissions are increased to meet communication demands, then data rate and throughput are improved, but interference between transmissions increases
Solution Approach 1:
Different devices are assigned to different subbands with locally optimized transmission parameters. Each device transmits on its assigned subbands with appropriate power levels and modulation schemes tailored to its specific channel conditions, allowing high data rates for individual devices while minimizing interference to other devices on different subbands.
3Productivity
If resource allocation is optimized for high-efficiency devices, then throughput for HE devices is improved, but compatibility with legacy devices may be compromised
Solution Approach 1:
The communication system implements a universal resource allocation framework where the same subband division mechanism serves both legacy and high-efficiency devices. Legacy devices can operate on assigned subbands using traditional protocols, while HE devices utilize the same subband structure with advanced features like multiple access points and enhanced modulation, ensuring compatibility across device types while optimizing for HE performance.
