Electronic Device Sub-Channel Communication With Dynamic WLAN Modes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless LAN communication systems face challenges when interference occurs in one of the sub-channels, leading to inefficiencies as they often disable the entire sub-channel set, which can affect devices that do not support preamble puncturing techniques, preventing effective communication.
Innovation Solution
A first device that performs wireless LAN communication switches between a first mode using all sub-channels and a second mode using a part of the sub-channels, disconnecting communication with devices unable to communicate in the second mode, thereby accommodating devices that do not support preamble puncturing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If communication is performed using all sub-channels in the sub-channel set, then communication efficiency is improved, but compatibility with devices unable to communicate in the second mode deteriorates
Solution Approach 1:
The system dynamically switches between first mode (using all sub-channels) and second mode (using a part of sub-channels) based on the communication state and device capabilities. This dynamic mode switching allows the system to optimize for communication efficiency when possible while maintaining compatibility when needed, resolving the contradiction between productivity and adaptability.
2Adaptability or versatility
If the second mode is started from the first mode, then adaptability to different device types is improved, but communication stability deteriorates due to mode switching
Solution Approach 1:
The system performs preliminary determination of the second device's communication capability before switching modes. By checking whether the second device can communicate in the second mode in advance, the system avoids unstable mode switching and ensures that mode changes only occur when compatible, thus maintaining communication stability while achieving device adaptability.
3Adaptability or versatility
If devices unable to communicate in the second mode are maintained, then device inclusivity is improved, but communication reliability deteriorates
Solution Approach 1:
The system extracts and identifies devices that are unable to communicate in the second mode, then disconnects them from the second mode communication. This allows the system to maintain high reliability for devices that can communicate in the second mode while still providing inclusivity by allowing those devices to connect in the first mode, effectively separating the device groups based on capability.

AI summary
A first device that performs wireless LAN communication, includes: a processing circuitry. The processing circuitry is configured to perform communication in any one of a first mode in which communication is performed using all sub-channels included in a sub-channel set including a plurality of continuous sub-channels used in the wireless LAN communication and a second mode in which communication is performed using a part of the sub-channels of the sub-channel set, and disconnect communication with a second device that is unable to communicate in the second mode in response to the processing circuitry starting the communication in the second mode from a state in which the processing circuitry performs the communication in the first mode.
