Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, data loss due to factors like multiple path interference and fading reduces system performance, and existing methods to prevent this, such as using low modulation order and repetition for important data, result in a waste of wireless resources.
Innovation Solution
A method and apparatus for data transmission in a communication system that involves determining and allocating data to a power boosting zone within each frame, where important data is power-boosted to enhance reception probability without wasting resources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If low modulation order and repetition are used for important data transmission, then data loss is prevented, but wireless resources are wasted
Solution Approach 1:
The patent applies local quality by differentiating transmission power across different zones within the frame. Important data (MAP, FCH) is transmitted in power-boosting zones with higher power, while less critical data uses normal power transmission. This localized power differentiation ensures reliable transmission of critical data without uniformly increasing power across the entire transmission, thus avoiding waste of wireless resources.
Solution Approach 2:
The patent segments the frame into power-boosting zones and normal zones based on data importance. The frame is divided into multiple sub-channels, and specific sub-channels are designated as power-boosting zones for critical data transmission. This segmentation allows the system to apply enhanced transmission only where necessary, resolving the contradiction between reliability and resource efficiency.
2Reliability
If repetition transmission is used for important data, then data loss is reduced, but system performance deteriorates due to resource waste
Solution Approach 1:
Instead of applying uniform repetition across all data transmissions, the patent applies local quality by providing repetition only for critical data (MAP, FCH) in power-boosting zones. This selective approach maintains high reliability for essential data while avoiding the productivity penalty of repeating all data, thus resolving the contradiction between reliability improvement and system performance maintenance.
Solution Approach 2:
The patent changes the transmission parameter (power level) dynamically based on data importance. Critical data is transmitted with elevated power in power-boosting zones, while non-critical data uses standard power. This parameter change allows the system to achieve reliable transmission of important data without the resource waste associated with uniform repetition, thereby maintaining system performance.
