Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication networks, the low-quality modulation scheme used for overhead information leads to inefficient use of resources and reduced bandwidth for user communications, as it must be universally decodable by all devices, even those far from the communication system, resulting in overcrowding and limited available bandwidth.
Innovation Solution
A method where the wireless communication system receives signal quality information from devices, determines a higher-order modulation scheme for overhead information, and transfers an indicator of this scheme to devices, allowing more efficient encoding and decoding of overhead data, thereby optimizing resource use and increasing available bandwidth.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a low-quality modulation scheme is used for overhead information to ensure universal decodability, then all wireless communication devices can decode the overhead, but the bandwidth for user communications is reduced and wireless resources are inefficiently used
Solution Approach 1:
The patent applies dynamics by transitioning from a static, fixed modulation scheme to a dynamic, adaptive modulation scheme. The system determines the appropriate modulation scheme based on real-time signal quality information received from wireless communication devices, allowing the modulation scheme to change dynamically according to channel conditions. This enables the system to optimize bandwidth availability while ensuring reliable overhead transmission.
Solution Approach 2:
The patent changes the parameter of modulation scheme order based on signal quality conditions. By selecting higher-order modulation schemes when signal quality permits, the system increases spectral efficiency and available bandwidth for user communications. The modulation scheme parameter is adjusted according to the determined signal quality, resolving the contradiction between reliability and productivity.
2Adaptability or versatility
If a low-quality modulation scheme is used for overhead information to ensure universal decodability, then all devices can receive the overhead, but more devices cannot connect simultaneously due to resource constraints
Solution Approach 1:
The patent applies local quality by tailoring the modulation scheme to the specific conditions of each wireless communication device based on its signal quality. Rather than using a uniform low-quality modulation for all devices, the system determines the appropriate modulation scheme for each device according to its individual signal conditions, allowing more devices to connect simultaneously while maintaining compatibility.
Solution Approach 2:
The system dynamically adjusts the modulation scheme based on real-time signal quality information from each device. This dynamic adaptation enables the network to accommodate more devices by optimizing the modulation scheme for each device's conditions, thereby increasing the quantity of connected devices while maintaining adaptability.
3Productivity
If a higher-order modulation scheme is used for overhead information to increase bandwidth efficiency, then more bandwidth is available for user communications, but not all devices can decode the overhead information
Solution Approach 1:
The patent implements feedback by receiving signal quality information from wireless communication devices and using this feedback to determine the appropriate modulation scheme. The system continuously monitors signal quality and adjusts the modulation scheme accordingly, ensuring that higher-order schemes are used only when signal conditions support reliable decoding, thus maintaining both bandwidth efficiency and decodability.
Solution Approach 2:
The system changes the modulation scheme parameter based on determined signal quality conditions. By selectively applying higher-order modulation schemes only when signal quality permits, the system optimizes bandwidth efficiency while ensuring that all devices can successfully decode the overhead information when using the selected scheme.
4Device complexity
If a fixed low-quality modulation scheme is used for overhead information, then the system is simple to implement, but wireless resources are wasted and network performance is limited
Solution Approach 1:
The patent transitions from a static, fixed modulation configuration to a dynamic, adaptive configuration. The system automatically determines the appropriate modulation scheme based on real-time signal quality information, eliminating the need for manual configuration while significantly improving network performance and resource utilization efficiency.
Solution Approach 2:
The system performs self-service by automatically determining the optimal modulation scheme based on signal quality information without requiring external intervention or complex manual configuration. The wireless communication system autonomously adjusts its operation to optimize performance, reducing configuration complexity while improving network productivity.
