Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication technologies face challenges in maximizing information density due to limited bandwidth, especially in high-density environments like urban centers and industrial sites, where congestion and interference are prevalent.
Innovation Solution
The method involves encoding information in amplitude variations within each message element of a wireless message, allowing for increased information density by multiplying the number of modulation states available for each message element.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the number of users expands in high-density environments, then network coverage is improved, but congestion and interference increase
Solution Approach 1:
The patent changes the modulation parameter from traditional phase-shift keying to amplitude-variation modulation, where information is encoded in the amplitude variations of the waveform within each message element. This allows multiple bits to be transmitted by detecting different amplitude patterns (e.g., constant amplitude, increasing amplitude, decreasing amplitude), thereby increasing spectral efficiency and reducing the need for additional frequency resources in high-density environments
2Quantity of substance
If traditional modulation schemes are used, then implementation complexity is low, but information density is limited
Solution Approach 1:
The patent introduces dynamic amplitude variation within each message element, where the amplitude can change over time according to predefined patterns. Instead of using static phase modulation, the system dynamically adjusts amplitude to encode multiple bits per message element, achieving higher information density while maintaining compatibility with existing wireless communication frameworks
3Productivity
If more bits are encoded in each message element, then transmission efficiency is improved, but susceptibility to interference increases
Solution Approach 1:
The patent exploits the harmful effect of amplitude variations (which normally cause interference and distortion) by intentionally introducing controlled amplitude changes within each message element to encode additional information. The receiver compensates for the resulting interference through signal processing, converting what would normally be a degradation into a beneficial encoding mechanism that increases transmission efficiency

AI summary
Additional information can be packed into each message element of a 5G/6G message by varying the amplitude of the signal within the symbol-time of the message element. For example, the difference between the amplitude at the beginning and ending of the symbol-time may encode additional bits, thereby providing higher information density in each transmission. The amplitude variation may be abrupt, such as a sudden change from the first amplitude value to the second amplitude value in the middle of the symbol-time, or it may be a gradual linear ramp spanning the symbol-time. In either case, the modulation scheme may include amplitude variation levels as well as the amplitude levels themselves, thereby providing a larger modulation space and hence shorter messages. Effects on crosstalk and frequency offset due to the amplitude variation, and their mitigation, are also disclosed.
