Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless standards that use only constellation-domain modulation do not support overlaid modulation scheduling, leading to restricted scheduling flexibility and potential imbalances in switching capabilities between different modulation domains due to the use of the same modulation switching interval for all domains.
Innovation Solution
Implementing a method to communicate signaling indicative of multiple modulation domains with distinct modulation switching intervals in a wireless communication network, allowing for flexible scheduling and efficient resource allocation by using different modulation switching intervals for each domain.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the same modulation switching interval is used for all modulation domains, then signaling complexity is reduced, but scheduling flexibility is restricted and switching capability balance is compromised
Solution Approach 1:
The patent divides the modulation switching control into separate intervals for different modulation domains (e.g., first modulation domain uses first switching interval, second modulation domain uses second switching interval). This segmentation allows each domain to be independently optimized for its specific requirements, resolving the contradiction between simplified signaling and flexible scheduling by applying different granularity levels to different domains.
Solution Approach 2:
The patent introduces dynamic modulation switching intervals that can be independently adjusted for each modulation domain based on traffic conditions, channel quality, and domain-specific requirements. This dynamic approach enables the system to adapt scheduling flexibility without uniformly increasing signaling complexity across all domains, as each domain can have its interval optimized independently.
2Ease of manufacture
If the same modulation switching interval is used for all modulation domains, then configuration simplicity is improved, but switching capability balance deteriorates
Solution Approach 1:
The patent applies different modulation switching intervals to different modulation domains based on their specific characteristics and requirements. For example, control channels may use longer intervals while data channels use shorter intervals. This local differentiation ensures that each domain's switching capabilities are balanced and optimized for its function, rather than forcing a uniform interval that compromises overall system reliability.
Solution Approach 2:
The patent changes the switching interval parameter independently for each modulation domain, allowing optimization of switching capabilities tailored to specific domain requirements. This parameter differentiation resolves the contradiction by enabling reliable, balanced switching performance across domains while maintaining configuration manageability through structured parameter control.
3Adaptability or versatility
If different modulation switching intervals are used for different modulation domains, then scheduling flexibility is enhanced, but signaling complexity increases
Solution Approach 1:
The patent segments the signaling overhead into domain-specific components, where each modulation domain has its own switching interval configuration. This segmentation allows scheduling flexibility to be enhanced for each domain independently while containing signaling complexity within manageable, localized scopes rather than requiring complex global coordination across all domains.
Solution Approach 2:
The patent implements dynamic modulation switching intervals that can be independently adjusted for each modulation domain based on real-time conditions. This dynamic approach enhances scheduling flexibility by allowing rapid adaptation in specific domains without requiring system-wide reconfiguration, thereby limiting the increase in overall signaling complexity to only the specific domains that need adjustment.
4Productivity
If different modulation switching intervals are used for different modulation domains, then resource allocation efficiency is improved, but system complexity increases
Solution Approach 1:
The patent applies different modulation switching intervals to different modulation domains based on their specific resource requirements and performance characteristics. This local optimization improves resource allocation efficiency for each domain while containing system complexity through structured, domain-specific parameter management rather than requiring complex global optimization mechanisms.
Solution Approach 2:
The patent independently adjusts the switching interval parameter for each modulation domain to optimize resource allocation efficiency. By changing this key parameter at the domain level rather than system-wide, the patent achieves improved productivity in specific domains while limiting the increase in overall system complexity to manageable, localized adjustments.

AI summary
In multi-domain modulation, also known as overlaid modulation, information is transmitted over more than one modulation domain. In such a transmission, different modulation domains are overlaid on top of each other. Signaling that is indicative of multiple modulation domains for overlaid modulation and is indicative of multiple modulation switching intervals is communicated in a wireless communication network, data modulated using the overlaid modulation is also communicated in the wireless communication network. The multiple modulation switching intervals include a respective modulation switching interval for each of the multiple modulation domains, and each respective modulation switching interval is different from other modulation switching intervals in the multiple modulation switching intervals.
