Solution Overview
Problem
Existing technologies lack a clear method for setting up a multi-AP candidate set in multi-AP coordination, failing to adequately clarify multi-AP capability information and allocate necessary parameters during the setup process.
Innovation Solution
A multi-AP coordination capability discovery procedure and frame structures are designed to facilitate the setup of a multi-AP candidate set, including the exchange of specific capability information through beacon frames and management frames, allowing for effective multi-AP coordination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If multi-AP coordination is introduced to improve transmission capability, then transmission capability is improved, but the complexity of setting up multi-AP candidate set increases
Solution Approach 1:
The patent applies preliminary action by having APs broadcast their multi-AP coordination capability information in advance through beacon frames before the actual coordination setup is needed. This allows other APs to discover and store the capability information proactively, reducing the complexity of the setup process when coordination is actually required.
Solution Approach 2:
The patent introduces management frames as intermediaries to facilitate the setup process. These frames carry standardized capability information elements that act as a mediator between APs, enabling them to exchange and understand each other's coordination capabilities without direct complex negotiation.
2Ease of operation
If capability information exchange is simplified, then setup process is simplified, but the precision of capability detection deteriorates
Solution Approach 1:
The patent applies local quality by including specific, detailed capability information elements within the standardized management frames. Each AP can selectively disclose relevant capability details (such as supported coordination modes, channel bandwidths, and power levels) at the appropriate granularity, ensuring precise capability detection while maintaining overall simplicity.
Solution Approach 2:
The patent segments the capability information into distinct elements within the management frames, such as separating multi-AP coordination capabilities from other AP parameters. This segmentation allows for precise detection of specific capabilities while keeping the overall exchange process simple and organized.
