Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the same time domain resources are used for multiple repetitions of uplink control information transmission, then device complexity is reduced and ease of operation is improved, but latency and reliability of transmission deteriorate

Engineering Contradiction:

Improvereliability of uplink control information transmissionVSAvoidcomplexity of time domain resource configuration

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent segments the time domain resources into multiple distinct sets (first set, second set, third set) for different repetitions of uplink control information transmission. Each set is configured with different time domain parameters, dividing the resource allocation into manageable segments that can be independently optimized for reliability while maintaining manageable complexity through structured segmentation.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent introduces dynamic resource allocation by configuring multiple different sets of time domain resources that can be selectively applied to different repetitions. This dynamic approach allows the system to adapt resource usage patterns to improve transmission reliability, moving away from static same-resource repetition while maintaining operational simplicity through pre-configured resource sets.

Inventive Principle:

Principle #15Dynamics

2Loss of time

If different sets of time domain resources are used for multiple repetitions of uplink control information transmission, then latency and reliability are improved, but device complexity increases

Engineering Contradiction:

Improvelatency of uplink control information transmissionVSAvoidcomplexity of time domain resource configuration

Core Design Contradiction:

Loss of timeVSDevice complexity

Solution Approach 1:

By segmenting time domain resources into multiple distinct sets with different time parameters, the patent enables optimized resource allocation for each repetition. This segmentation allows selective use of resources that minimize latency while maintaining manageable complexity through structured organization of resource sets.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent applies parameter changes by configuring different time domain parameters (such as time offsets, resource block allocations) across multiple resource sets. This allows optimization of transmission timing and resource usage to reduce latency, while the systematic approach to parameter variation keeps device complexity manageable.

Inventive Principle:

Principle #35Parameter changes

3Reliability

If the same time domain resources are used for multiple repetitions, then ease of operation is improved, but communication performance deteriorates

Engineering Contradiction:

Improvecommunication performanceVSAvoidease of resource configuration

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent segments time domain resources into multiple pre-configured sets, each optimized for different transmission scenarios. This segmentation improves communication performance by enabling diverse resource usage patterns while maintaining ease of operation through pre-configuration, as the complexity is managed at setup rather than execution time.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent implements preliminary action by pre-configuring multiple sets of time domain resources before transmission occurs. This allows the system to have diverse resource options ready for improving communication performance, while the base station handles the complexity of configuration in advance, keeping operation simple during actual transmission.

Inventive Principle:

Principle #10Preliminary action
