Solution Overview
Problem
Wireless local area networks (WLANs) face challenges in efficiently managing resources to provide bandwidth and response times due to multiple devices sharing resources, with limitations from communication protocols and hardware bandwidth, particularly when operating with both new and legacy protocols.
Innovation Solution
The implementation of a radio architecture that includes radio front-end module (FEM) circuitry, radio IC circuitry, and baseband processing circuitry, enabling efficient scheduling of location measurement reports, traffic indication maps, and other information during beacon intervals, and supporting both WLAN and Bluetooth functionalities, allowing for coexistence and efficient resource utilization across different protocols and bandwidths.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple devices share the same wireless resources, then network coverage and device connectivity are improved, but resource allocation efficiency and bandwidth availability deteriorate
Solution Approach 1:
The patent divides the wireless medium into discrete resource units (RUs) that can be independently allocated to different devices. This segmentation allows the system to manage multiple devices efficiently by assigning specific frequency-time resources to each device, thereby maintaining high connectivity while improving resource allocation efficiency through granular control.
Solution Approach 2:
The patent implements dynamic resource allocation where the assignment of resource units to devices changes based on real-time network conditions, device requirements, and traffic demands. This dynamic approach enables the system to adapt to varying connectivity needs while optimizing bandwidth utilization and resource efficiency across the network.
2Productivity
If resource units are allocated contiguously, then resource aggregation and transmission efficiency are improved, but flexibility in accommodating non-contiguous frequency resources and legacy protocol compatibility deteriorate
Solution Approach 1:
The patent creates a universal resource allocation framework that can handle both contiguous and non-contiguous resource unit assignments. The system maintains compatibility with legacy protocols by supporting traditional contiguous allocations while simultaneously enabling non-contiguous allocations for newer protocols, making the system multi-functional and adaptable to different protocol requirements without sacrificing transmission efficiency.
Solution Approach 2:
The patent enables dynamic switching between contiguous and non-contiguous resource allocation modes based on protocol requirements and network conditions. This flexibility allows the system to optimize transmission efficiency for contiguous allocations when working with legacy devices while accommodating non-contiguous frequency resources when needed for modern protocols or specific transmission requirements.
3Productivity
If bandwidth is increased to provide more resources, then data rate and capacity are improved, but hardware complexity and protocol management overhead increase
Solution Approach 1:
The patent segments the increased bandwidth into multiple manageable resource units, each of which can be independently allocated and managed. This segmentation reduces protocol management overhead by breaking down complex bandwidth allocation into simpler, discrete unit assignments, while still providing the high data rates and capacity associated with increased bandwidth through the aggregation of multiple resource units.
