Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Current Wi-Fi technology lacks a standardized method to indicate the sensing measurement type during a WLAN sensing procedure, which can lead to inefficiencies and misconfigurations in scenarios like location discovery and proximity detection.

Innovation Solution

A communication method is introduced where an initiator determines a radio frame with indication information that specifies whether the WLAN sensing measurement procedure is trigger-based (TB) or non-trigger-based (non-TB), and sends this frame to a responder.

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The sensing measurement type indication is segmented into distinct fields within the radio frame structure. The indication information is separated into specific bits or fields that can be independently parsed, allowing the receiver to efficiently identify the sensing measurement type without processing the entire frame complexity.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The sensing measurement type is indicated in advance within the radio frame before the actual sensing measurement procedure begins. This preliminary indication allows the responder to prepare appropriately in advance, ensuring efficient and accurate execution of the sensing procedure without requiring complex real-time decisions.

Solution Approach 1:

Specific bits or fields within the radio frame are designated with local quality to indicate the sensing measurement type. These specific locations within the frame structure provide clear, unambiguous indication of the measurement type, ensuring reliable configuration while maintaining overall frame structure simplicity through localized information placement.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

Different sensing measurement types are indicated through distinct bit patterns or field values that act as visual identifiers within the radio frame. These distinct indicators ensure clear differentiation between TB and non-TB sensing measurements, improving configuration reliability through unambiguous type identification.
