Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication devices face challenges in maintaining communication quality and speed due to interference between different wireless communication standards, particularly when using the same frequency band, leading to dropped throughput and frame loss.
Innovation Solution
A wireless communication device with a first and second wireless communication section that analyzes the communication status signal of the second section to determine synchronization, allowing data transmission during non-communication periods in synchronization with the second section's timing, thereby preventing interference and frame loss.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If uniform time division communication control is applied, then communication interference is prevented, but throughput drops
Solution Approach 1:
The patent implements dynamic communication control by analyzing the communication status signal to determine whether the second wireless communication is synchronous or asynchronous. Based on this analysis, the first wireless communication section dynamically adjusts its transmission timing - using non-communication periods when synchronous, or implementing time division when asynchronous. This dynamic adaptation resolves the contradiction by preventing interference during synchronous operations while maintaining throughput during asynchronous operations.
Solution Approach 2:
The patent changes the communication control parameter from fixed uniform time division to variable timing based on synchronization status. By monitoring the communication status signal and detecting synchronization patterns, the system adjusts transmission timing parameters in real-time, allowing optimal performance in both synchronous and asynchronous scenarios.
2Reliability
If priority is always given to high-quality data communication, then frame loss is prevented for high-priority data, but other wireless communication is interrupted causing frame loss
Solution Approach 1:
The patent introduces feedback through the communication status signal that continuously reports the operational state of the second wireless communication. The first wireless communication section uses this feedback to intelligently determine when to transmit data, ensuring high-quality data communication receives priority when needed while allowing other communications to proceed without unnecessary interruptions.
Solution Approach 2:
The system dynamically adjusts transmission priority based on real-time communication status analysis. Rather than static priority assignment, the patent implements dynamic priority control where the first wireless communication section adapts its timing based on whether the second communication is synchronous or asynchronous, resolving the contradiction between priority assurance and communication continuity.
3Reliability
If antennas are separated adequately to avoid power interference, then communication quality improves, but device size increases
Solution Approach 1:
The patent substitutes the mechanical/physical solution of antenna separation with a control-based solution. Instead of physically distancing antennas to avoid interference, the system uses signal analysis and timing control to manage interference electronically, allowing compact antenna placement while maintaining communication quality through intelligent transmission scheduling.

AI summary
In a wireless communication device for performing plural wireless communications with different standards using the same frequency band, degradation of communication quality and communication speed due to communication interference is prevented, while drop in throughput and occurrence of frame loss are prevented. A first wireless communication section first performs wireless communication using a first frequency band and a second wireless communication section performs second wireless communication using a second frequency band with which at least a part of the first frequency band overlaps. The first wireless communication section analyzes a communication status signal which represents a signal pattern corresponding to communication status of the second wireless communication and then determines whether it is synchronous communication, and if it is, the first wireless communication section transmits/receives data in a non-communication period when communication in the synchronous communication is not performed, in synchronization with timing of the synchronous communication.
