Solution Overview

Problem

Existing wireless device communication systems are limited to single-link operations, lacking the ability to establish simultaneous multiple links through a singular access point, which restricts the upper layer's connection to the lower layer.

Innovation Solution

The implementation of a multi-link re-setup mechanism using Multi-Link Devices (MLDs) that allow for the establishment of multiple links between an access point MLD and a non-AP MLD via a single request frame and response frame, enabling the change and management of entry point mappings through a distributed system medium.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If single-link operation is used, then device complexity is reduced, but the ability to establish simultaneous multiple links is limited

Engineering Contradiction:
Improveability to establish simultaneous multiple linksVSAvoidmulti-link operation complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent segments the link management process by introducing separate setup and teardown procedures for multi-link operations. The association request frame and disassociation frame are divided into specific fields that handle individual link identification and management, allowing multiple links to be established and managed independently while maintaining systematic control.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent adds a new dimension to wireless communication by introducing multi-link operation capability. This is achieved by incorporating link identification fields and multi-link specific parameters into the existing association and disassociation frames, enabling simultaneous operation across multiple links without fundamentally redesigning the entire protocol stack.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Ease of operation

If multi-link re-setup mechanism is implemented, then link management flexibility is improved, but communication protocol complexity increases

Engineering Contradiction:
Improvelink management flexibilityVSAvoidcommunication protocol complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent applies preliminary action by pre-defining the structure of association request and disassociation frames with specific fields for multi-link management. The Link ID field, Multi-Link Setup field, and other parameters are prepared in advance within the frame structures, enabling flexible link management operations without requiring complex real-time protocol negotiations.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent utilizes parameter changes by introducing new fields and modifying existing parameters in the association and disassociation frames. The Link ID parameter, Multi-Link Setup parameter, and other control fields are changed or added to enable flexible link management, allowing the system to adapt to different multi-link configurations while maintaining protocol structure.

Inventive Principle:
Principle #35Parameter changes

3Productivity

If multiple links are established through a single access point, then communication capacity is enhanced, but entry point mapping management becomes more difficult

Engineering Contradiction:
Improvecommunication capacityVSAvoidentry point mapping management
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent introduces an intermediary mechanism through the access point that manages entry point mappings for multiple links. The association frame and disassociation frame structures include specific fields that enable the access point to track and manage the mapping between distributed system medium entry points and multiple wireless links, simplifying the management complexity through structured intermediary control.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

This disclosure describes systems, methods, and devices related to an extreme high throughput (EHT) signaling structure. A device may establish a communication channel with one or more station devices (STAs). The device may generate an extreme high throughput signal field (EHT-SIG) of a header, wherein the EHT-SIG field comprises information associated with resource allocations (RUs). The device may generate a frame comprising the header. The device may assign a first RU to a first station device. The device may assign a second RU to the first station device, wherein the first RU or the second RU is an aggregation of a 26-tome RU and a neighboring RU. The device may cause to send the frame to the first station device.
