Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Future wireless communications networks face challenges in efficiently handling diverse data traffic profiles and conflicting resource allocations for different quality of service requirements, particularly in systems supporting Ultra Reliable Low Latency Communications (URLLC) and other services with varying latency, reliability, and data rates.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple communications resources are allocated to support different services with varying QoS requirements, then service diversity and adaptability are improved, but resource conflicts and transmission reliability deteriorate
Solution Approach 1:
The patent applies local quality by assigning different priority levels to different communications resources based on their service requirements. High-priority resources are allocated to URLLC services while lower-priority resources serve eMBB services. This differentiated quality assignment resolves the contradiction by ensuring that critical services receive guaranteed resources while maintaining overall system diversity.
Solution Approach 2:
The patent introduces a priority-based resource selection mechanism as an intermediary between resource allocation and data transmission. When resource conflicts occur, the intermediary mechanism selects resources based on priority levels, preventing direct conflicts from compromising transmission reliability. This mediator layer enables multiple services to coexist without mutual interference.
2Productivity
If communications resources are allocated for multiple services simultaneously, then system capacity and productivity are improved, but resource conflicts and transmission delays increase
Solution Approach 1:
The patent segments communications resources into distinct priority levels (high-priority and lower-priority resources) based on service requirements. This segmentation allows the system to maintain high capacity by allocating resources to multiple services while preventing delays through clear separation of critical and non-critical transmissions. High-priority URLLC data receives dedicated resources that are protected from lower-priority traffic.
Solution Approach 2:
By assigning different quality attributes (priority levels) to different resource segments, the patent enables simultaneous optimization for both capacity and delay. High-priority resources are optimized for low-latency URLLC services while lower-priority resources handle throughput-intensive eMBB services, resolving the contradiction between system capacity and transmission delay.
3Productivity
If overlapping communications resources are used to maximize resource utilization, then efficiency is improved, but data transmission reliability and latency performance worsen
Solution Approach 1:
The patent resolves this contradiction by applying local quality differentiation to overlapping resources. When resources overlap in time or frequency, the system identifies the priority level of each resource and assigns transmission precedence accordingly. High-priority URLLC transmissions are guaranteed to use their designated resources without interference from lower-priority traffic, maintaining latency performance while allowing efficient utilization of non-critical resources.
Solution Approach 2:
The priority-based selection mechanism acts as an intermediary that manages overlapping resources. When multiple resources overlap, the intermediary evaluates their priority levels and selects appropriate resources for transmission. This prevents low-priority traffic from occupying high-priority resources, thereby maintaining latency performance while maximizing overall resource utilization efficiency.
