Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless Access Point (AP) systems face challenges in efficiently coordinating transmit power with Automated Frequency Coordination (AFC) frequency response, leading to potential interference and suboptimal power usage across channels, especially in shared bands like the 6 GHz band.
Innovation Solution
The implementation of interoperable Transmit Power Envelop (TPE) signaling with AFC frequency response, where APs receive AFC information, determine necessary mask alterations, and report TPE values to allow clients to maximize power usage while adhering to AFC constraints, ensuring compliance by sliding IEEE masks up or down over punctured channels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If APs use fixed transmit power levels, then power management is simple, but interference occurs and power usage is suboptimal in shared bands
Solution Approach 1:
The patent implements dynamic transmit power adjustment by receiving AFC frequency response information and dynamically modifying TPE values based on channel conditions. The AP slides IEEE masks up or down over punctured channels to adapt power levels in real-time, transforming static power management into a dynamic system that responds to environmental conditions.
Solution Approach 2:
The system incorporates feedback mechanisms by receiving AFC frequency response information about channel conditions and using this feedback to adjust TPE signaling and transmit power levels. The AP continuously monitors channel state and modifies power allocation based on this feedback, creating a closed-loop control system that optimizes performance while minimizing interference.
2Productivity
If APs maximize power usage, then throughput is improved, but compliance with AFC constraints is violated causing interference
Solution Approach 1:
The patent changes key parameters including TPE values, mask positions, and power allocation coefficients based on AFC frequency response information. By dynamically adjusting these parameters, the system maximizes throughput within the bounds of AFC compliance, transforming fixed parameter systems into adaptive ones that optimize performance while respecting regulatory constraints.
Solution Approach 2:
The system performs preliminary actions by pre-calculating mask positions and TPE adjustments based on received AFC information before actual transmission. This preliminary processing ensures that power allocation is optimized in advance while guaranteeing compliance with AFC constraints, rather than attempting compliance adjustments after throughput optimization.
3Adaptability or versatility
If TPE signaling is simplified for compatibility, then interoperability is maintained, but precision in power control is reduced
Solution Approach 1:
The patent adds another dimension to TPE signaling by incorporating mask position parameters and frequency response indices alongside traditional power values. This multi-dimensional approach maintains compatibility with existing TPE frameworks while adding precision through additional parameters that describe mask sliding positions and frequency-specific power adjustments.
Solution Approach 2:
The system uses IEEE masks as intermediaries between simplified TPE signaling and precise power control requirements. The masks act as a translation layer that converts coarse TPE power indications into fine-grained power allocation across frequency channels, maintaining interoperability while achieving precision through the mask sliding mechanism.

AI summary
Interoperable Transmit Power Envelop (TPE) signaling with Automated Frequency Coordination (AFC) frequency response may be provided. First, AFC information may be received. Next a mask may be determined for a punctured channel indicated in the AFC information. Then a first amount may be determined that the mask needs to be altered to reach an AFC response for the punctured channel indicated in the AFC information. A Transmit Power Envelop (TPE) value may then be reported for the punctured channel comprising the first amount plus a second amount.
