Hierarchical Radio Resource Partitioning for 5G Slice QoS
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
5G NR standalone networks have limited coverage compared to non-standalone networks, hindering the full utilization of network slicing capabilities, and there is a need for consistent user experience across both types of networks.
Innovation Solution
Implementing hierarchical management of radio resources by dividing them into partitions based on network slice IDs, Subscriber Profile Identifiers (SPIDs), Quality-of-Service (QoS) indices, and Class Indices (QCIs), with priority-based scheduling to ensure consistent user experience across 5G NR standalone and non-standalone networks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If 5G NR standalone networks are deployed, then network slicing capability is improved, but coverage area is reduced compared to non-standalone networks
Solution Approach 1:
The patent segments radio resources into distinct partitions: SA-dedicated resources for 5G NR standalone networks and shared resources for both SA and NSA networks. This segmentation allows network slicing to be implemented in SA networks while maintaining coverage through NSA network fallback, resolving the contradiction between improved adaptability and reduced coverage area.
2Reliability
If priority-based resource allocation is implemented, then Quality of Service for high-priority users is improved, but system complexity increases
Solution Approach 1:
The patent applies local quality by assigning different priority levels to different resource partitions based on user profiles and service requirements. High-priority users receive preferential treatment in resource allocation within their designated partitions, while maintaining manageable system complexity through structured partitioning rules and profile-based management.

AI summary
A radio resource partitioning system may be configured to: divide a resource grid into first partitions based on: subscriber profile identifiers (SPIDs); a combination of SPIDs and network slice identifiers (IDs); or one or more network slice IDs and no SPID. The radio resource partitioning system may further divide the first partitions into second partitions based on Fifth Generation (5G) Quality-of-Service (QoS) Identifiers (5QIs) or QoS class Identifiers (QCIs); generate partition information based on the first partitions and the second partitions; and provide the partition information to a scheduler for scheduling data for transmission to or reception from a User Equipment device (UE).
