Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If channel repetitions are transmitted without beam parameter determination based on reference repetition occasions, then device complexity is reduced, but communication reliability deteriorates due to inability to adapt to varying interference levels

Engineering Contradiction:
Improvecommunication reliabilityVSAvoidbeam parameter determination complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The system performs preliminary identification of reference repetition occasions and determines beam parameters in advance based on these reference occasions. By pre-determining beam parameters using reference occasions identified from multiple channel repetitions, the system prepares optimal beam configurations before actual data transmission, thereby improving communication reliability without adding complex real-time decision-making requirements during transmission.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system enables devices to autonomously identify reference repetition occasions from received channel repetitions and self-determine appropriate beam parameters based on these identified references. This self-service mechanism allows devices to automatically adapt to varying interference levels and network topologies without requiring complex external control, thereby improving reliability while keeping device complexity manageable through autonomous operation.

Inventive Principle:
Principle #25Self-service

2Productivity

If beam parameters are determined dynamically for each channel repetition, then communication efficiency is improved, but device complexity increases due to additional processing requirements

Engineering Contradiction:
Improvecommunication efficiencyVSAvoidprocessing complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The system segments the beam parameter determination process by identifying specific reference repetition occasions within the series of channel repetitions. Instead of processing every repetition equally, the system divides the repetitions into reference occasions (used for beam parameter determination) and non-reference occasions (used for data transmission). This segmentation enables efficient communication by applying beam parameters determined from reference occasions to multiple subsequent transmissions, thereby improving productivity while reducing processing complexity compared to determining parameters for each individual repetition.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The determined beam parameters from reference repetition occasions are applied universally across multiple channel repetitions and potentially across different channels (PUCCH, PUSCH, PDCCH, PDCH). This multi-functional application allows a single beam parameter determination process to serve multiple transmission purposes and multiple channels, thereby improving communication efficiency while avoiding the need for separate processing for each channel or repetition, thus managing device complexity effectively.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Adaptability or versatility

If reference repetition occasions are identified from multiple channel repetitions, then adaptability to varying interference levels is improved, but loss of time occurs due to additional identification processing

Engineering Contradiction:
Improveadaptability to interference levelsVSAvoidtime for identification processing
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The system performs reference repetition occasion identification and beam parameter determination as preliminary actions during the initial phase of channel repetition reception. By identifying reference occasions and determining beam parameters in advance before actual data transmission begins, the system enables adaptability to varying interference levels without incurring time delays during the critical transmission phase. The time investment for identification is made beforehand, allowing rapid and adaptive transmission once parameters are established.

Inventive Principle:
Principle #10Preliminary action
