Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

In 5G mobile communication systems, time domain overlap between high-priority and low-priority services hinders effective transmission of high-priority services, as existing technologies lack a solution to ensure reliable transmission of high-priority channels or signals when they overlap with low-priority ones.

Innovation Solution

A method where a terminal cancels the transmission of low-priority objects and prioritizes the transmission of high-priority objects based on the presence of downlink control information (DCI), ensuring that high-priority physical channels or signals are transmitted even when there is resource overlap, by implementing specific timing criteria for transmission cancellation and prioritization.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If resource overlap occurs between high-priority and low-priority services, then transmission resources are shared, but effective transmission of high-priority service cannot be ensured

Engineering Contradiction:

Improvetransmission reliability of high-priority serviceVSAvoidtransmission delay

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The patent changes the transmission parameter by dynamically adjusting the transmission state based on priority levels. When resource overlap is detected, the system changes the transmission parameter from simultaneous transmission to selective transmission, where only the high-priority service maintains transmission while the low-priority service is cancelled. This parameter change resolves the contradiction by ensuring high-priority transmission reliability without incurring additional delay.

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

Instead of treating all overlapping transmissions equally, the patent inverts the conventional approach by giving preferential treatment to high-priority services. The system inverts the normal transmission behavior by cancelling low-priority transmissions when overlap occurs, thereby ensuring that high-priority services are not delayed. This inversion resolves the contradiction by prioritizing critical transmissions over non-critical ones.

Inventive Principle:

Principle #13The other way round (Inversion)

2Adaptability or versatility

If different channels have different starting symbols and lengths, then resource flexibility increases, but time domain overlap occurs in transmission resources

Engineering Contradiction:

Improveresource allocation flexibilityVSAvoidtransmission reliability during overlap

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent applies local quality by treating different transmission resources differently based on their priority levels. Instead of applying a uniform transmission rule to all channels, the system applies different rules: high-priority channels maintain transmission while low-priority channels are cancelled during overlap. This localized differentiation resolves the contradiction by maintaining reliability for critical services while preserving resource flexibility for non-critical services.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The patent segments the transmission resources into high-priority and low-priority categories. By dividing the transmission space into priority-based segments, the system can apply different transmission strategies to each segment. This segmentation allows the system to maintain flexibility in resource allocation while ensuring reliability for high-priority transmissions by isolating them from low-priority interference.

Inventive Principle:

Principle #1Segmentation

3Reliability

If no transmission solution exists for resource overlap, then system complexity remains low, but effective transmission of high-priority service cannot be ensured

Engineering Contradiction:

Improvehigh-priority service transmissionVSAvoidtransmission control complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent implements self-service by enabling the transmission system to automatically detect resource overlap and make priority-based decisions without external intervention. The terminal device autonomously identifies when high-priority and low-priority services overlap and automatically cancels low-priority transmissions. This self-service mechanism resolves the contradiction by ensuring high-priority transmission reliability through automated priority management, adding minimal complexity to the system.

Inventive Principle:

Principle #25Self-service
