Solution Overview

Problem

In New Radio (NR) systems, such as 5G applications, data transmission resources for different service scenarios like eMBB, URLLC, and mMTC often overlap in the time domain, leading to conflicts that hinder efficient data transmission.

Innovation Solution

A data transmission method and device that perform transmission of scheduling information using overlapping transmission resources, prioritizing data transmission on resources with higher priority data and optimizing resource usage by determining which resources have corresponding demodulation pilots to avoid interference and maximize efficiency.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If transmission resources for different service scenarios are allocated to meet diverse service requirements, then system adaptability is improved, but resource conflicts in time domain occur leading to transmission reliability deterioration

Engineering Contradiction:
Improveservice scenario adaptabilityVSAvoidtransmission reliability
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The patent applies local quality by making different parts of the transmission resource have different functions. Specifically, when transmission resources overlap in time domain, the patent determines which resource to prioritize based on the service type (eMBB, URLLC, or mMTC) and transmits data only on the selected resource while canceling transmission on the other. This ensures that each local resource allocation is optimized for its specific service requirement, maintaining both adaptability and reliability.

Inventive Principle:
Principle #3Local quality

2Quantity of substance

If transmission resources are increased to accommodate multiple service types, then service coverage is improved, but resource conflict and interference increase

Engineering Contradiction:
Improvetransmission resource quantityVSAvoidinterference
Core Design Contradiction:
Quantity of substanceVSObject-generated harmful factors

Solution Approach 1:

The patent converts the harmful effect of resource overlap and potential interference into a benefit by establishing a systematic resource selection mechanism. When transmission resources overlap in time domain, the patent uses service type identification and priority determination to select which resource to activate, thereby converting the potential harm of resource conflict into an organized resource allocation strategy that maintains system efficiency and reduces actual interference.

Inventive Principle:
Principle #22Blessing in disguise (Convert harm into benefit)

3Productivity

If data transmission is performed on overlapping resources to maximize resource utilization, then productivity is improved, but demodulation accuracy deteriorates due to interference

Engineering Contradiction:
Improvedata transmission efficiencyVSAvoiddemodulation accuracy
Core Design Contradiction:
ProductivityVSMeasurement precision

Solution Approach 1:

The patent extracts the conflicting element from the system by identifying and eliminating the source of interference. When transmission resources overlap in time domain, the patent determines which resource to prioritize and cancels transmission on the non-selected resource. This extraction approach ensures that only one data stream is transmitted on the overlapping time resource, thereby maintaining high productivity while ensuring accurate demodulation without interference from concurrent transmissions.

Inventive Principle:
Principle #2Taking out (Extraction)
