Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If multiple communication links are established in Wi-Fi devices according to IEEE 802.11be standard, then data transmission capability and processing capability are improved, but link coordination complexity and management difficulty increase

Engineering Contradiction:
Improvedata transmission capabilityVSAvoidlink coordination complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent segments the multi-link management process into distinct phases: link establishment phase (using ADDTS request frames), data transmission phase, and acknowledgment phase. Each phase is handled independently with specific protocol operations, reducing the overall coordination complexity while maintaining multiple active links for improved productivity

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent applies preliminary action by establishing traffic streams and allocating resources before actual data transmission begins. The ADDTS (Add Traffic Stream) mechanism pre-configures multiple communication links with specific parameters (data rate, delay bound, burst size) so that when data needs to be transmitted, the links are already ready and coordinated, reducing real-time management complexity

Inventive Principle:
Principle #10Preliminary action

2Productivity

If traffic streams are established on multiple communication links simultaneously, then data flow processing capability is improved, but resource allocation complexity increases

Engineering Contradiction:
Improvedata flow processing capabilityVSAvoidresource allocation complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent implements a universal resource allocation mechanism through the ADDTS framework that can handle multiple traffic streams across multiple links simultaneously. The same ADDTS request frame structure and negotiation process can be applied to any combination of links, providing a multi-functional solution that reduces allocation complexity while improving data flow processing capability

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent uses parameter changes in the ADDTS request frames to dynamically adjust traffic stream characteristics (data rate, delay bound, burst size, priority) for each link based on current network conditions and requirements. This allows flexible resource allocation across multiple links without requiring complex dedicated management for each stream, thereby improving productivity while controlling complexity

Inventive Principle:
Principle #35Parameter changes

AI summary

Embodiments of the present application provide a wireless local area network communication method, a device, a medium, and an electronic apparatus. The wireless local area network communication method comprises: selecting, according to a data stream to be transmitted, a first communication link and at least one second communication link from candidate communication links; generating an add traffic stream request frame comprising indication information used to indicate the at least one second communication link; and sending, via the first communication link, the add traffic stream request frame, in which the add traffic stream request frame is used to request traffic streams for transmitting the data stream to be separately established on the first communication link and the at least one second communication link. The technical solutions of the embodiments of the present application establish traffic streams on multiple communication links by sending an add traffic stream request frame on one communication link, such that the multiple communication links can simultaneously support one traffic stream, thereby enhancing the capability of processing data streams, and accordingly improving transmission efficiency of the data streams.
