Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge of using discontinuous frequency bands in Wi-Fi systems to achieve ultra-high bandwidth and extremely high throughput is hindered by the occupancy of supported frequency bands by other systems, leading to inefficient spectrum resource utilization.
Innovation Solution
A coded bit distribution method that performs channel coding on information bits using a modulation and coding scheme (MCS), and then distributes the coded bits to multiple channel sets or resource units, allowing transmission in both continuous and discontinuous frequency bands.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If discontinuous frequency bands are used to avoid occupation by other systems, then spectrum resource utilization is improved, but data transmission efficiency deteriorates due to idle channel gaps
Solution Approach 1:
The patent segments the codebook into multiple codebook groups and distributes coded bits across multiple channel sets or resource units. This segmentation allows the system to utilize discontinuous frequency bands effectively by filling idle gaps with coded bits from different segments, thereby improving both spectrum resource utilization and maintaining data transmission efficiency.
Solution Approach 2:
The patent introduces a new dimension of codebook group indexing and distributed mapping across multiple channel sets. By transforming the traditional single-channel codebook structure into a multi-dimensional distributed structure, the system can utilize discontinuous frequency bands without sacrificing transmission efficiency, as coded bits are strategically placed across available channels.
2Productivity
If ultra-high bandwidth is supported using more frequency bands, then throughput is improved, but spectrum availability deteriorates due to discontinuous frequency bands
Solution Approach 1:
The codebook is segmented into multiple codebook groups that can be independently mapped to different channel sets. This segmentation enables the system to achieve ultra-high throughput by distributing data across multiple discontinuous frequency bands while maintaining efficient codebook utilization, as each codebook group can be optimally assigned to available spectrum resources.
Solution Approach 2:
The patent changes the parameter of codebook mapping by introducing codebook group indices and distributed mapping rules. This parameter change allows the system to adapt to discontinuous spectrum availability while maintaining ultra-high throughput, as the mapping parameters can be dynamically adjusted to utilize available frequency bands regardless of their continuity.
3Quantity of substance
If coded bits are distributed to multiple channel sets or resource units, then spectrum resource utilization is improved, but system complexity increases
Solution Approach 1:
The codebook is divided into multiple codebook groups with simple indexing rules. This segmentation approach improves spectrum resource utilization by enabling distributed mapping across multiple channel sets while keeping system complexity manageable through the use of straightforward indexing and selection mechanisms rather than complex allocation algorithms.
Solution Approach 2:
The distributed mapping mechanism uses self-service principles where codebook groups are automatically assigned to channel sets or resource units based on predefined rules and indices. This reduces system complexity by eliminating the need for complex centralized allocation decisions, as the mapping process is self-directed through systematic indexing and distribution rules.
