Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional wireless communication devices struggle to effectively identify or distinguish repetition of control information, leading to degraded operation.

Innovation Solution

The method involves receiving and analyzing control information formats to determine if a second control information is a repeat of a first control information based on format and index, utilizing monitoring periods and SS sets, and establishing associations between SS sets to identify and drop repeated control information.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If conventional UE processes all received control information, then all control information is handled, but processing efficiency degrades due to repeated control information

Engineering Contradiction:

Improvecontrol information processing efficiencyVSAvoidenergy consumption from processing repeated information

Core Design Contradiction:

ProductivityVSLoss of energy

Solution Approach 1:

The patent applies preliminary action by establishing association relationships between SS sets in advance, and using bitmap indicators to pre-identify repeated control information before full processing occurs. This allows the UE to quickly determine which control information to skip, avoiding unnecessary processing of repeated transmissions.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent extracts and identifies repeated control information using format comparison and bitmap indicators, then separates it from legitimate control information. This extraction allows the system to remove repeated information from the processing queue, improving overall processing efficiency and reducing energy consumption.

Inventive Principle:

Principle #2Taking out (Extraction)

2Productivity

If conventional UE identifies repeated control information, then processing efficiency improves, but identification accuracy is insufficient

Engineering Contradiction:

Improvecontrol information processing speedVSAvoidrepeated information identification accuracy

Core Design Contradiction:

ProductivityVSMeasurement precision

Solution Approach 1:

The patent implements feedback mechanisms where the UE continuously monitors control information formats, compares them against stored formats, and uses bitmap indicators to verify repetitions. This multi-layer feedback approach ensures high accuracy in identifying repeated information while maintaining fast processing speeds through iterative validation.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The patent replaces complex mechanical comparison processes with format-based identification and bitmap indicator systems. Instead of deep content analysis, the system uses structural format matching and pre-configured bitmap patterns to rapidly and accurately identify repeated control information.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Adaptability or versatility

If the system monitors multiple SS sets with different monitoring periods, then coverage is improved, but complexity of managing monitoring occasions increases

Engineering Contradiction:

Improvemonitoring flexibility across different SS setsVSAvoidcomplexity of managing multiple monitoring occasions

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies universality by creating a unified association relationship framework that works across multiple SS sets with different monitoring periods. The bitmap indicator mechanism serves multiple functions simultaneously: identifying repetitions, managing associations, and coordinating across different monitoring occasions, thereby reducing overall system complexity despite increased versatility.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent segments the monitoring management into independent SS set associations, each with its own bitmap indicators and association relationships. This segmentation allows each SS set to be managed independently while maintaining overall coordination, reducing the complexity of managing multiple monitoring occasions with different periods.

Inventive Principle:

Principle #1Segmentation
