Non-Contiguous Channel Aggregation for High Throughput Wireless
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Achieving high throughput in wireless communication networks above 1 Gbps is challenging due to the low likelihood of allocating wide bandwidth channels, often hindered by interference, overlapping networks, and regulatory limitations.
Innovation Solution
Implementing a system that utilizes non-contiguous wireless communication channels, each with a bandwidth of at least 80 MHz, allowing for simultaneous transmission and reception of wireless communication packets across multiple channels with independent transmission characteristics, including bandwidth, modulation, and coding schemes, to achieve aggregated bandwidths exceeding 160 MHz.

Engineering Contradiction Analysis
1Productivity
If a wide bandwidth channel is allocated to achieve high throughput, then the throughput increases, but the likelihood of successful allocation decreases due to interference and regulatory limitations
Solution Approach 1:
The patent divides a wide bandwidth channel into multiple non-contiguous sub-channels, each with independent allocation. This segmentation allows the system to achieve the aggregate bandwidth of a wide channel while avoiding the interference and allocation issues of a single continuous wide channel, as each sub-channel can be independently selected from available spectrum resources.
Solution Approach 2:
The patent transitions from allocating a single continuous frequency band to allocating multiple non-contiguous frequency segments across the spectrum. This dimensional change in resource allocation allows the system to achieve wide aggregate bandwidth while navigating around interference zones and regulatory restrictions that would block a single continuous allocation.
2Productivity
If multiple non-contiguous channels are used to achieve wide aggregate bandwidth, then the throughput increases, but the system complexity increases
Solution Approach 1:
The patent combines multiple non-contiguous sub-channels into a unified communication stream with a single MAC layer. This merging approach allows the system to achieve wide aggregate bandwidth through multiple channels while maintaining simplified protocol handling and resource management at the MAC layer, reducing the complexity that would otherwise arise from managing multiple independent channels.
Solution Approach 2:
The patent creates a universal MAC layer that can handle multiple non-contiguous sub-channels with a single set of protocols and procedures. This multi-functional MAC layer can dynamically allocate and manage any combination of available sub-channels, reducing system complexity by providing a unified interface rather than requiring separate handling for each channel.
3Adaptability or versatility
If independent transmission characteristics are used for each channel, then the adaptability increases, but the device complexity increases
Solution Approach 1:
The patent implements dynamic transmission characteristics for each sub-channel, where modulation and coding schemes can be independently adjusted based on channel conditions. This dynamic adaptability allows each sub-channel to optimize its performance independently while being managed through a unified MAC layer, achieving high versatility without proportionally increasing device complexity through centralized control.
