Wi-Fi Frame Control Using BQR for Multi-AP Resource Allocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing IEEE802.11 series standards lack clear methods for efficiently collecting information on communication resources in multi-AP coordination configurations, leading to potential collisions and inefficient operation.
Innovation Solution
A communication apparatus is provided with a determination unit to assess UL MU communication capability, an acquisition unit to obtain a BQR representing available communication resources, and a decision unit to allocate resources based on the acquired BQR, enabling efficient resource management among multiple APs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multi-AP coordination configuration is implemented to improve throughput, then communication efficiency is improved, but resource collision occurs due to lack of clear information collection methods
Solution Approach 1:
The patent applies preliminary action by having the access point determine UL MU communication capability and acquire BQR information before actually allocating communication resources. This advance preparation allows the system to identify available resources and avoid collisions before they occur, resolving the contradiction between improving throughput through multi-AP coordination and preventing resource collisions.
2Productivity
If resource information is collected from connected apparatuses, then resource allocation efficiency is improved, but communication overhead increases
Solution Approach 1:
The patent extracts only the necessary BQR (Bandwidth Quality Report) information from connected apparatuses that is needed for resource allocation, rather than collecting all possible communication information. This selective extraction improves resource allocation efficiency while minimizing communication overhead by transmitting only the essential resource state data.
3Speed
If UL MU communication is enabled for all apparatuses, then communication speed is improved, but resource management complexity increases
Solution Approach 1:
The patent applies dynamics by making UL MU communication capability determination dynamic rather than static. The access point determines whether each connected apparatus supports UL MU communication on a per-connection basis, allowing the system to optimize communication speed for capable devices while simplifying resource management for devices that don't support it, thus resolving the complexity issue.

AI summary
A communication apparatus complying with an IEEE802.11 series standard, determines, based on information received from another communication apparatus connected to the communication apparatus, whether UL MU (Uplink Multiuser) communication of the other communication apparatus is enabled or disabled, acquires, from the other communication apparatus by a method according to a result of the determination, a BQR (Bandwidth Query Report) representing a state of a communication resource usable by the other communication apparatus, and decides the communication resource used to communicate with the other communication apparatus based on the acquired BQR.
