Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

The IEEE 802.11bf standard for WLAN sensing lacks specifications for reporting sensing measurement results, particularly for non-trigger based sensing measurement instances, leading to ambiguity on when and how APs should send measurement results back to STAs.

Innovation Solution

The proposed solution involves defining parameters for immediate and delayed reporting of sensing measurement results in non-trigger based sensing measurement instances, with negotiation between the non-AP STA and AP on reporting requirements, and specifying the use of Sensing Measurement Report frames to convey measurement results.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If WLAN sensing measurements are performed without defined reporting specifications, then measurement flexibility is maintained, but reporting ambiguity and inconsistency occur

Engineering Contradiction:

Improvemeasurement flexibilityVSAvoidreporting consistency

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent introduces configurable reporting parameters including reporting trigger conditions (threshold-based, event-based, periodic), reporting intervals, and measurement types. These parameter changes enable the system to adapt reporting behavior to different application requirements while maintaining consistency through standardized parameter definitions and negotiation mechanisms between AP and STAs.

2Loss of time

If immediate reporting of sensing measurements is implemented, then measurement result availability is improved, but communication overhead and power consumption increase

Engineering Contradiction:

Improvemeasurement result availabilityVSAvoidpower consumption

Core Design Contradiction:

Loss of timeVSUse of energy by moving object

Solution Approach 1:

The patent implements dynamic reporting mechanisms where the reporting mode (immediate, periodic, or event-triggered) is negotiated and can be changed between AP and STAs based on application requirements. The system can switch between different reporting strategies - immediate reporting when fast response is needed, periodic reporting for power savings, or event-triggered reporting based on measurement thresholds, optimizing the balance between response time and power consumption.

3Measurement precision

If detailed sensing measurement reports are transmitted frequently, then measurement precision is maintained, but network bandwidth consumption increases

Engineering Contradiction:

Core Design Contradiction:

Measurement precisionVSQuantity of substance

Solution Approach 1:

The patent enables selective reporting where different measurement parameters are reported with different frequencies and levels of detail based on their importance and application requirements. Critical measurements can be reported immediately with high precision, while less critical measurements use periodic or event-triggered reporting with reduced detail, optimizing the balance between measurement accuracy and bandwidth consumption.

AI summary

An access point station (AP) configured for wireless local area network (WLAN) sensing may be configured to perform a sensing measurement setup with a non-AP station (non-AP STA). The sensing measurement setup may comprise an exchange of sensing measurement request and response frames to establish sensing measurement parameters for one or more sensing measurement instances including trigger-based and non-trigger based sensing measurement instances. The AP may perform sensing measurements with the non-AP STA by transmitting and/or receiving one or more null-data packets (NDPs) for a sensing measurement instance. The NDPs may be configured in accordance with the sensing measurement parameters. For performing a non-trigger based sensing measurement instance when the AP is operating a sensing responder and when reporting was indicated in a sensing measurement setup request frame received from the non-AP STA, the AP may encode a sensing measurement report for transmission to the non-AP STA.
