Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless local area network (WLAN) technologies lack a specific procedure for announcement transmission intervals (ATIs) in AP coordination scenarios, leading to inefficiencies and interference between multiple access points (APs).
Innovation Solution
A communication method and apparatus that involves a first AP generating an indication frame to coordinate interaction procedures with second APs and stations (STAs) in ATIs, using scheduling modes to ensure timely and comprehensive service demand management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If multiple APs are densely deployed to expand coverage, then network coverage is improved, but interference between APs increases and service coordination becomes complex
Solution Approach 1:
The patent introduces an intermediary coordination mechanism where APs exchange capability information and coordinate service delivery through structured communication protocols. This intermediary approach allows multiple APs to operate in dense deployments while managing interference through coordinated resource allocation and service assignment.
Solution Approach 2:
The patent creates a universal coordination framework that enables multiple APs to perform diverse functions (service delivery, interference management, resource allocation) through a common protocol structure. This multi-functional approach allows the system to handle various coordination scenarios uniformly, reducing complexity despite dense AP deployment.
2Reliability
If AP coordination procedures are established to reduce interference, then service quality is improved, but system complexity increases
Solution Approach 1:
The patent segments the coordination procedure into distinct phases: capability information exchange, service demand identification, and coordinated service delivery. Each phase has specific protocols and message structures, reducing overall complexity by breaking down the coordination process into manageable, standardized steps.
Solution Approach 2:
The patent utilizes parameter-based coordination where APs exchange structured capability information (parameters) that define their service abilities. By changing and adjusting these parameters dynamically, the system achieves reliable service quality while maintaining manageable complexity through parameterized control rather than complex procedural logic.
3Productivity
If structured interaction protocols are implemented for AP coordination, then service delivery efficiency is improved, but communication overhead increases
Solution Approach 1:
The patent implements preliminary action by having APs exchange capability information in advance before actual service delivery is needed. This pre-coordination allows the system to establish service assignments and resource allocations beforehand, improving service delivery efficiency while reducing the need for extensive real-time communication during actual service provision.

AI summary
A communication method and apparatus are provided, which relate to the field of communication technologies, to determine an interaction procedure in an ATI in an AP coordination scenario. The method includes: A C-AP generates a first indication frame, where the first indication frame indicates an interaction procedure between an M-AP, the C-AP, and a STA in the ATI; and the C-AP sends the first indication frame to a plurality of M-APs, so that the plurality of M-APs perform the interaction procedure in the ATI based on the first indication frame.
