Multi-Link Hub Mode Selection for Signal-Interference Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless local area networks (WLANs) face challenges in efficiently determining the operation mode for multiple links between electronic devices and hub devices, particularly due to signal interference and suboptimal channel settings, which affect data transmission and reception efficiency.
Innovation Solution
An electronic device employs a communication module to receive management frames from hub devices, determine default channel settings, and generate target channel settings to optimize the operation mode for simultaneous data transmission and reception, switching to alternative modes if interference occurs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple links are established between electronic device and hub device, then data transmission capacity is improved, but signal interference increases
Solution Approach 1:
The patent segments the communication channels by assigning different frequency bands to different links. The electronic device divides the available spectrum into multiple frequency channels, allowing simultaneous data transmission on multiple links without mutual interference. This segmentation approach enables multiple links to coexist by spatially separating their frequency resources.
Solution Approach 2:
The patent introduces frequency as an additional dimension for resource allocation. Instead of using the same frequency channel for all links, the system operates in the frequency domain by assigning different frequency bands to different links. This dimensional expansion allows multiple links to transmit data simultaneously without interference.
2Device complexity
If default channel setting information is used, then device complexity is reduced, but data transmission efficiency deteriorates
Solution Approach 1:
The patent implements a feedback mechanism where the electronic device monitors the quality of data transmission on each link. Based on this feedback information regarding transmission performance, the device dynamically adjusts channel settings to optimize efficiency. The system continuously receives feedback on transmission quality and modifies frequency allocations accordingly.
Solution Approach 2:
The patent transforms static default channel settings into dynamic adaptive configurations. The system continuously monitors transmission quality and adjusts channel parameters in real-time based on current network conditions. This dynamic approach allows the system to adapt to changing environmental factors and optimize performance continuously.
3Productivity
If first mode is determined usable with target channel setting information, then data transmission efficiency is improved, but determination process complexity increases
Solution Approach 1:
The patent performs preliminary determination of the first mode's usability before actual data transmission begins. The system evaluates whether the first mode can be used based on pre-assessed channel conditions and interference levels. This preliminary assessment prevents unnecessary transmission attempts and reduces overall processing complexity by making decisions in advance.

AI summary
An electronic device is configured to determine default channel setting information on a plurality of links with at least one hub device, based on a received management frame, determine whether a first mode is usable, in which, in the first mode, data is transmitted to the at least one hub device through a first link based on the default channel setting information, and, at the same time, data is received from the at least one hub device through a second link, when the first mode is determined to be not usable, generate target channel setting information, determine whether the first mode is usable based on the target channel setting information, and, when the first mode is determined to be usable based on the target channel setting information, determine an operation mode of the plurality of links to be the first mode.
