Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems that use multiple channels for data transmission, such as LTE, experience a decrease in overall transmission rate when some channels experience a decrease in transmission rate, leading to system-wide performance degradation.
Innovation Solution
An information processing device and method that evaluates multiple channels based on an evaluation function, selects optimal channels for data transmission, and includes retransmission capabilities to maintain data integrity and rate, utilizing channel evaluation units, a channel selection unit, and a transmission control unit to dynamically adjust data routing and retransmit missing data items.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple channels are used for data transmission to increase overall transmission rate, then the system transmission rate is improved, but when some channels experience rate decrease, the entire system transmission rate decreases
Solution Approach 1:
The patent implements dynamic channel selection by continuously evaluating channel conditions and switching between channels based on real-time transmission rate measurements. The channel evaluation unit dynamically assesses each channel's performance, and the channel selection unit switches data transmission to alternative channels when detected degradation occurs, making the system adaptable to changing channel conditions rather than static
Solution Approach 2:
The patent changes the operational parameter of channel selection based on transmission rate conditions. When the transmission rate of a channel falls below a predetermined threshold, the system switches to a different channel with better transmission characteristics. This parameter change approach allows the system to maintain optimal performance by adjusting channel usage based on real-time rate measurements
2Reliability
If channel evaluation and selection mechanisms are added to prevent rate decrease, then system reliability is improved, but device complexity increases
Solution Approach 1:
The channel evaluation unit automatically measures and evaluates channel transmission rates without external intervention, and the channel selection unit autonomously switches channels based on evaluation results. The system performs self-monitoring and self-adjustment, eliminating the need for complex external control mechanisms while maintaining high reliability
Solution Approach 2:
The patent implements a feedback loop where the channel evaluation unit continuously monitors transmission rates and provides feedback to the channel selection unit. When degradation is detected, the feedback mechanism triggers channel switching. This closed-loop feedback system maintains simplicity by using automatic responses to channel conditions rather than complex decision-making algorithms
