Extended TWT Element for Larger Bandwidth Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional Target Wake Time (TWT) elements in wireless communications are limited in the types of parameters they can convey and values they can support, struggling to accommodate newer technologies and larger bandwidths, such as those exceeding 160 MHz, which are needed for high-throughput stations.
Innovation Solution
The extension of TWT elements to include additional information beyond conventional limits, allowing for the signaling of larger bandwidths and new parameters through extended TWT elements or new TWT information frames, enabling support for higher bandwidths and advanced features like finer time granularity and spatial multiplexing modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional TWT elements are used, then backward compatibility is maintained, but the capability to support larger bandwidths and newer technologies is limited
Solution Approach 1:
The TWT element is divided into a basic TWT element containing standard parameters and an extended TWT element containing additional parameters. This segmentation allows the basic element to maintain backward compatibility while the extended element provides support for larger bandwidths and newer technologies without increasing the complexity of the fundamental structure.
Solution Approach 2:
The extended TWT element is nested within or alongside the basic TWT element structure. The extension includes a header portion identifying it as an extended element and a body portion containing additional parameters, allowing it to be integrated into the existing TWT framework while providing enhanced functionality.
2Adaptability or versatility
If TWT element extensions are added to support larger bandwidths and new parameters, then adaptability to newer technologies is improved, but the complexity of the element structure increases
Solution Approach 1:
The extension is segmented into a header portion (containing element ID and length fields) and a body portion (containing additional parameters). This segmentation allows the extension to be processed independently and only when needed, reducing the overall complexity impact while maintaining support for newer technologies.
Solution Approach 2:
The extended TWT element acts as an intermediary between the basic TWT element and the new technology requirements. It provides a bridge that allows existing TWT infrastructure to work with enhanced parameters for larger bandwidths and newer features without requiring complete system redesign.
3Loss of information
If conventional TWT parameter sets are used, then simplicity of implementation is maintained, but the ability to convey additional information is limited
Solution Approach 1:
The information conveyance capability is segmented into standard parameters in the basic TWT element and additional parameters in the extended TWT element. This allows the system to convey more information without requiring the entire element structure to be complex, as only the extension portion contains the additional information.
Solution Approach 2:
The extension adds a new dimension to the TWT element by including a body portion with additional parameters beyond the standard set. This dimensional expansion allows conveyance of extra information (such as extended TWT parameters) without fundamentally changing the core element structure.
