Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If PUCCH resources are allocated using conventional methods, then the system can maintain basic uplink control channel transmission, but the uplink channel transmission efficiency is insufficient

Engineering Contradiction:
Improveuplink channel transmission efficiencyVSAvoidPUCCH resource allocation complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent applies parameter changes by systematically varying multiple PUCCH resource parameters including starting symbol indices (e.g., symbols 9 and 12), orthogonal cover code (OCC) indices (0 and 1), and physical resource block (PRB) offsets. By changing these parameters across 16 different PUCCH resources in a resource set, the system achieves better transmission efficiency through optimized resource selection without adding significant system complexity

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent segments the PUCCH resources into distinct configurations within a resource set, where each resource is defined by specific combinations of starting symbol, OCC index, and PRB offset. This segmentation allows the UE to select from multiple pre-defined resource options (16 resources total) rather than allocating resources dynamically, improving transmission efficiency while maintaining manageable complexity

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If the number of PUCCH resources is increased to 16 resources with multiple parameters, then resource allocation flexibility improves, but resource determination complexity increases

Engineering Contradiction:
ImprovePUCCH resource allocation flexibilityVSAvoidPUCCH resource determination complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements preliminary action by pre-configuring 16 PUCCH resources with specific parameter combinations (starting symbols 9/12, OCC indices 0/1, PRB offsets) before transmission. The UE receives this configuration in advance and can directly select from the pre-defined resources based on transmission needs, achieving high flexibility without real-time computation complexity

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent manages complexity through systematic parameter changes across the 16 resources, where each resource varies specific parameters (starting symbol, OCC index, PRB offset) in a controlled manner. This structured parameter variation provides diverse resource options for different transmission scenarios while maintaining deterministic resource selection rules

Inventive Principle:
Principle #35Parameter changes
