Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple frequency bands are combined for operation, then spectrum utilization and system efficiency are enhanced, but device complexity and configuration difficulty increase
Solution Approach 1:
The patent combines multiple frequency bands (TDD, SUL, SDL, FDD) into a unified soft band operation framework, allowing the system to treat multiple bands as a single operational entity. This merging approach enables flexible spectrum utilization while managing device complexity through unified configuration and management mechanisms.
Solution Approach 2:
The soft band operation creates a universal framework that can handle multiple band types (TDD, SUL, SDL, FDD) and configurations through a single operational mode. This multi-functionality allows the system to adapt to different spectrum conditions and requirements without requiring separate handling mechanisms for each band type.
2Area of stationary object
If multiple bands are operated simultaneously, then coverage and capacity are improved, but latency and resource allocation complexity increase
Solution Approach 1:
The soft band operation introduces dynamic flexibility in band configuration and resource allocation. The system can dynamically adjust which bands are active and how resources are distributed across bands based on current traffic conditions and requirements, thereby optimizing coverage while minimizing latency through adaptive resource management.
Solution Approach 2:
The patent enables parameter changes in band configuration, allowing the system to adjust operational parameters such as bandwidth allocation, carrier aggregation settings, and duplex mode configurations. These parameter changes facilitate optimized coverage and reduced latency by adapting to varying network conditions and traffic patterns.
3Adaptability or versatility
If flexible band combinations are implemented, then adaptability to different communication requirements is enhanced, but system configuration and management difficulty increase
Solution Approach 1:
The soft band operation framework provides universality by creating a single operational mode that can accommodate multiple band types and configurations. This universal approach enhances adaptability to different communication requirements while simplifying operation through unified configuration and management, eliminating the need for separate handling of each band type.
Solution Approach 2:
Instead of managing each band type separately with complex individual configurations, the patent inverts the approach by creating a unified soft band operation that encompasses multiple bands. This inversion simplifies operation and management by treating diverse band combinations as a single operational entity with standardized procedures.
Data Source
AI summary
Wireless communications may include improved flexibility for spectrum utilization. Spectrum utilization may be improved by deriving a flexible or soft band from a combination of multiple bands. The combination may be with bands with the same or different kinds of duplex mode. The flexible or soft band may be utilized in single band operation or by a single cell despite being a combination of bands.
