Solution Overview
Problem
Mobile communication apparatuses in wireless communication networks face challenges in reducing power consumption and efficiently utilizing available wireless channels, as they often rely on single channels and have limited battery life due to high energy usage.
Innovation Solution
The method involves determining the availability of multiple sub-channels and simultaneously using them to transmit divergent copies of a data segment, allowing for efficient data transmission and reception, which reduces power consumption and extends battery life by optimizing receiver duty cycles and error correction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple sub-channels are used simultaneously for data transmission, then channel utilization efficiency is improved, but device complexity increases
Solution Approach 1:
The patent segments the wireless communication channel into multiple sub-channels, allowing simultaneous transmission of divergent copies of data segments. This segmentation enables parallel data transmission across different sub-channels, improving channel utilization efficiency while managing device complexity through structured signal processing operations including sequential reception, identification of divergent copies, and reconstruction of original data segments.
2Use of energy by moving object
If receiver duty cycle is reduced to save power, then energy consumption is improved, but data reception reliability may deteriorate
Solution Approach 1:
The patent applies preliminary action by transmitting divergent copies of data segments across multiple sub-channels before the receiver needs to process them. The receiver can reconstruct the original data segment from any sufficient subset of received copies, allowing the receiver to operate with reduced duty cycle while maintaining reliability through the redundancy of pre-transmitted copies.
Solution Approach 2:
The patent changes the parameter of data transmission by using divergent copies with different properties transmitted across multiple sub-channels. This allows the receiver to obtain sufficient data information through fewer active reception periods, reducing energy consumption while maintaining data reception reliability through the diverse information content of multiple copies.
