Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems in 5G networks do not specify communication range requirements for different service data units, failing to meet their transmission needs.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If communication range information is not specified for different service data units, then the system structure remains simple, but the transmission requirements of different service data units cannot be met
Solution Approach 1:
The patent segments communication range information into discrete identifiers (PPP-CR values 0-7) that can be independently assigned to different service data units. This segmentation allows the system to handle diverse transmission requirements without creating a completely new complex framework, as each SDU can be tagged with a simple numeric identifier that maps to pre-defined range characteristics.
Solution Approach 2:
The patent applies local quality by allowing different service data units within the same service to have different communication range identifiers. Instead of applying a uniform communication range policy across all data, the system enables fine-grained differentiation at the SDU level, where each data unit receives appropriate range treatment based on its specific transmission requirements.
2Reliability
If communication range identifiers are introduced for each service data unit, then transmission requirements can be met, but the complexity of information processing increases
Solution Approach 1:
The patent creates a universal communication range identifier system that serves multiple functions: it identifies transmission range requirements, maps to logical channel groups, and guides resource allocation. This single PPP-CR identifier mechanism handles what would otherwise require multiple separate parameter sets, reducing overall information processing complexity while maintaining comprehensive transmission control.
Solution Approach 2:
The patent transforms communication range requirements into discrete parameter values (PPP-CR 0-7) that can be efficiently processed and stored. By converting continuous or complex range specifications into a standardized finite parameter set, the system reduces processing overhead while maintaining the ability to distinguish between different transmission requirements.
3Measurement precision
If mapping relationships between communication range information and logical channel groups are established, then transmission accuracy improves, but system configuration complexity increases
Solution Approach 1:
The patent establishes mapping relationships between communication range identifiers and logical channel groups in advance, before actual data transmission occurs. These pre-configured mappings allow the system to quickly determine appropriate transmission parameters without performing complex real-time calculations, thereby improving transmission accuracy while minimizing runtime processing complexity.
