Solution Overview
Problem
Existing WiFi networks lack dynamic mechanisms for efficient mode changes between stations (STAs) that optimize network resource utilization and performance.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If dynamic operating mode changes are implemented between STAs, then network efficiency and resource utilization are improved, but device complexity and protocol overhead increase
Solution Approach 1:
The patent implements dynamic operating mode changes allowing STAs to transition between different communication modes (e.g., from stationary to mobile mode) based on real-time conditions. This dynamic adaptation enables the network to optimize resource allocation and communication parameters according to actual STA behavior, thereby improving network efficiency and productivity.
Solution Approach 2:
The patent utilizes parameter changes by modifying operational parameters such as transmission mode, power level, and communication protocol based on detected STA conditions. By changing these parameters dynamically, the system achieves better resource utilization and network performance without requiring complete protocol redesign.
2Adaptability or versatility
If transient mode changes are allowed with automatic reversion, then adaptability to changing conditions is improved, but time loss and instability increase
Solution Approach 1:
The patent implements periodic evaluation of STA conditions to determine when mode changes should occur and when automatic reversion should be triggered. By using periodic checking mechanisms, the system achieves adaptability to changing conditions while controlling the duration of transient modes through time-based thresholds, thereby reducing unnecessary time loss.
Solution Approach 2:
The patent employs feedback mechanisms where STAs report their operational status and conditions back to the network, enabling intelligent decision-making about mode changes. This feedback loop allows the system to adapt to real-time conditions while minimizing unnecessary mode transitions and associated time losses through criteria-based activation.
3Ease of operation
If new frame elements are introduced for mode change initiation, then ease of operation and control is improved, but device complexity and implementation difficulty increase
Solution Approach 1:
The patent designs new frame elements that serve multiple functions within the existing WiFi protocol structure. These frame elements can be used for mode change initiation, status indication, and coordination purposes, thereby improving ease of operation without requiring completely separate control mechanisms. The universal design allows existing STAs to utilize these elements with minimal additional complexity.

AI summary
Methods and structures are disclosed that permit a station (STA) operating in a WIFI network to initiate a dynamic operating mode change between a pair of STAs in which the mode change may be transient and the STAs may change back to an original mode after the end of a transmission operation (TXOP), after a certain time defined in mode change parameters/frames and/or after certain one or more criteria are met.
