Wi-Fi 6 Resource Allocation via Trigger Frame Countdown
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current Wi-Fi 6 communication systems based on the IEEE 802.11ax standard face challenges in real-time resource allocation due to hardware limitations, requiring additional memory space for buffering and analysis, which increases costs and hinders efficient resource management.
Innovation Solution
A resource allocation method and system that utilizes a trigger frame signal to determine random access resource units, employing countdown and offset parameters to enable real-time selection of resource units without the need for high-capacity memory, allowing communication terminals to compete and select resources efficiently.

Engineering Contradiction Analysis
1Productivity
If additional memory space is introduced for buffering and analyzing resource information, then resource allocation capability is improved, but hardware cost increases
Solution Approach 1:
The patent extracts only the necessary resource information from the trigger frame signal rather than buffering all resource information. The terminal device selectively processes and buffers only the specific resource allocation data needed for its operation, reducing memory requirements while maintaining allocation capability
Solution Approach 2:
The patent implements partial processing of resource information by bufferizing only the necessary portion of resource data rather than all available data. This partial action approach reduces memory usage while sufficient for real-time resource allocation decisions
2Productivity
If additional memory space is introduced for buffering and analyzing resource information, then resource allocation capability is improved, but real-time allocation is hindered
Solution Approach 1:
The patent extracts only the essential resource information from the trigger frame signal for buffering and processing. By selectively extracting and buffering only the necessary resource allocation data rather than all resource information, the system achieves real-time processing capability while maintaining adequate resource allocation functionality
Solution Approach 2:
The patent implements partial processing of resource information by bufferizing only the necessary portion of resource data. This partial action approach reduces processing time and enables real-time resource allocation while sufficient for operational needs

AI summary
A resource allocation method includes the following steps: receiving a trigger frame signal, analyzing the trigger frame signal for acquiring at least one first user information field, determining at least one first random access resource unit number according to the at least one first user information field, decreasing a countdown parameter to generate a first countdown result according to the at least one first random access resource unit number, determining whether to continuously receive the trigger frame signal according to the first countdown result, and selecting a first random access resource unit from multiple random access resource units of the at least one first user information field when the trigger frame signal is not continuously received.
