Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If wireless communication systems use traditional scheduling and resource allocation methods, then system stability is maintained, but flexibility and efficiency deteriorate when coexisting with URLLC, eMBB, and MMTC services

Engineering Contradiction:

ImproveflexibilityVSAvoidscheduling complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent segments the communication system into different service types (URLLC, eMBB, MMTC) with dedicated handling mechanisms. Each service type is assigned specific resource allocation strategies and scheduling priorities, allowing the system to manage diverse services independently while maintaining overall flexibility.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent implements dynamic resource allocation where scheduling parameters, resource blocks, and transmission configurations are adjusted in real-time based on service requirements and channel conditions. This dynamic approach enables the system to adapt to varying traffic patterns and service priorities without rigid predefined structures.

Inventive Principle:

Principle #15Dynamics

2Adaptability or versatility

If wireless communication systems allocate resources for multiple service types, then service coverage is expanded, but latency increases due to resource contention and scheduling overhead

Engineering Contradiction:

Improveservice coverageVSAvoidlatency

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

Solution Approach 1:

The patent reserves dedicated resources and pre-configures transmission parameters for URLLC services before actual data transmission is needed. This preliminary preparation ensures that when URLLC traffic arrives, resources are immediately available without scheduling delays, thus reducing latency while maintaining multi-service support.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent applies different resource allocation strategies tailored to each service type's specific requirements. URLLC receives prioritized resource allocation with guaranteed low latency, while eMBB and MMTC utilize more flexible resource sharing mechanisms, optimizing overall system performance without uniform treatment.

Inventive Principle:

Principle #3Local quality

3Reliability

If wireless communication systems prioritize URLLC transmissions, then reliability and latency performance improve, but resource allocation complexity increases

Engineering Contradiction:

ImproveURLLC reliabilityVSAvoidresource allocation complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent introduces an intermediary scheduling mechanism that mediates between URLLC priority requirements and overall resource allocation. This intermediary layer translates high-level service requirements into specific resource assignments, simplifying the complexity of direct resource management while ensuring URLLC reliability through controlled priority handling.

Inventive Principle:

Principle #24Intermediary (Mediator)

4Productivity

If wireless communication systems use fixed communication structures, then system stability is maintained, but efficiency deteriorates when handling diverse service types

Engineering Contradiction:

Solution Approach 1:

The patent replaces fixed communication structures with dynamic configurations that adapt to service requirements. Transmission parameters, resource allocations, and scheduling decisions are continuously adjusted based on real-time channel conditions and traffic patterns, improving efficiency while managing complexity through standardized adaptation mechanisms.

AI summary

A user equipment (UE) is described. The UE includes a processor and memory in electronic communication with the processor. Instructions stored in the memory are executable to transmit or receive an ultra-reliable low latency communication (URLLC) transmission that overrides a downlink (DL) schedule or interferes on an uplink (UL) transmission with an enhanced mobile broadband (eMBB) transmission or a massive machine type communication (MMTC) transmission.
