Wireless Communication Channel Map Control via Dynamic Slave Grouping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing wireless communication systems face increased processing loads and costs when managing multiple slave devices, as they require high-performance computers to perform channel map control for all devices simultaneously, leading to potential communication quality issues and high system costs.
Innovation Solution
A wireless communication system that selectively determines communication quality and channel usage for only a subset of slave devices, dynamically changing the execution target for channel map control to avoid fixed channel quality issues and reduce processing loads, thereby maintaining effective communication without the need for high-performance computers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If channel map control is performed for all slave devices simultaneously, then communication quality can be maintained, but processing load and system costs increase significantly
Solution Approach 1:
The patent segments the set of all slave devices into multiple groups, where only one group is selected as the execution target for channel map control at any given time. This segmentation allows the master device to manage channel quality assessment in a distributed and time-division manner, reducing the instantaneous processing load while maintaining overall communication quality through periodic coverage of all devices.
Solution Approach 2:
The patent implements dynamic selection of execution targets by randomly or sequentially choosing different slave devices or groups across multiple communication cycles. This dynamic approach ensures that no single device bears a fixed heavy load, and all devices receive periodic channel quality assessment, balancing processing distribution while maintaining reliable communication across the network.
2Productivity
If high-performance computers are used for channel map control, then processing capability is sufficient, but system costs increase
Solution Approach 1:
The patent applies partial action by performing channel map control on only a subset of slave devices (one execution target group) at each communication cycle rather than all devices simultaneously. This partial execution reduces the processing requirements to levels that can be handled by conventional, lower-cost computers while still achieving effective channel management through periodic assessment of all devices over time.
3Reliability
If channel map control is performed frequently for all devices, then communication quality is maintained, but processing load increases
Solution Approach 1:
The patent implements periodic action by cycling through different execution target groups across multiple communication cycles. Each slave device group receives channel map control periodically rather than continuously, which maintains communication quality through regular assessment while distributing the processing time burden across the system, preventing any single device from experiencing excessive processing delays.

AI summary
A wireless communication system includes a master device and multiple slave devices. Each slave device executes a wireless communication with the master device using a communication channel sequentially selected from multiple communication channels. The wireless communication system is configured to: determine, in the wireless communication between the master device and each of the plurality of slave devices, a communication quality of each of the multiple communication channels; determine at least one target communication channel to be used for the wireless communication based on a determination result of the communication quality of each of the multiple communication channels; and repeatedly select, from the plurality of slave devices, an execution target of determination of the at least one target communication channel to be used for the wireless communication.
