Measurement Apparatus With Segmented 320 MHz Resource Unit Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In the IEEE 802.11be standard, the selection of resource units for measurement is not freely selectable, leading to user mistakes and decreased usability due to small graphic forms and difficulty in understanding resource unit selection, especially when the frequency bandwidth is 320 MHz.
Innovation Solution
A measurement apparatus that displays resource units in a selectable manner, dividing the frequency bandwidth into multiple screens with distinct display modes for easy selection and designation of desired measurement targets, allowing users to select resource units based on predefined standards.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the frequency bandwidth is 320 MHz and all resource units are displayed on one screen, then the complete resource unit information is visible, but the graphic forms become small and difficult to understand
Solution Approach 1:
The patent divides the 320 MHz frequency bandwidth into multiple screens, displaying resource units in different frequency ranges on separate displays. This segmentation allows each screen to show larger, more readable graphic forms while still representing the complete set of resource units across all screens.
2Measurement precision
If resource units are selected according to standard requirements, then measurement accuracy is maintained, but user selection freedom is reduced and mistakes occur
Solution Approach 1:
The patent provides visual feedback by displaying which resource units are selectable according to standard requirements and which are not. The display clearly indicates the selection status of each resource unit, helping users understand the standard constraints while maintaining selection freedom within the allowed ranges.
3Ease of operation
If the graphic form size is increased for better visibility, then usability improves, but the number of resource units that can be displayed on one screen decreases
Solution Approach 1:
The patent segments the resource unit display across multiple screens, allowing each screen to display fewer resource units with larger, more visible graphic forms. This maintains both visibility and comprehensive coverage of all resource units.
Solution Approach 2:
The patent transitions from a single-screen display to a multi-screen display arrangement, utilizing the spatial dimension across multiple displays to accommodate both large graphic forms and comprehensive resource unit coverage simultaneously.

AI summary
A measurement apparatus includes a display part that displays an image, and a control part that displays a plurality of resource unit display parts, which are graphic forms indicating resource units disposed in a frequency bandwidth of a channel, on the display part in a selectable manner in a case in which measurement of communication in accordance with a standard of IEEE 802.11be is performed, that divides the frequency bandwidth of the channel into two or more frequency bandwidths to display only the plurality of resource unit display parts belonging to one of the divided frequency bandwidths in a case in which the frequency bandwidth of the channel is equal to or greater than a predetermined value, and that allows selection of at least one of the plurality of resource unit display parts to allocate a resource unit as a measurement target.
