Radio Resource Slicing for Flexible Service Allocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing radio frame structures in mobile communications, such as LTE/LTE-A, are inflexible and inefficient in accommodating various service requirements like low latency and massive connectivity due to fixed allocation units for subcarriers and symbol resources.
Innovation Solution
A method and apparatus that split radio resources into multiple slices based on frequency, time, power, or code resources, allowing for flexible configuration of radio frame tiles and beam slices tailored to specific service types, enabling dynamic allocation across primary and secondary cell networks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If radio resources are allocated using fixed allocation units (subcarrier and symbol resources) as in LTE/LTE-A, then the system maintains simple structure and ease of operation, but it cannot flexibly accommodate various service requirements such as low latency and massive connectivity
Solution Approach 1:
The patent applies segmentation by dividing the radio frame structure into multiple types (first type with first allocation unit, second type with second allocation unit) that can be selectively used. This allows the system to segment resources according to different service requirements, enabling flexible accommodation of various services while maintaining manageable complexity through structured division.
Solution Approach 2:
The patent implements dynamics by enabling dynamic selection and configuration of different radio frame types and allocation units based on service requirements. The system can dynamically adjust the allocation unit size and frame structure to match the specific needs of different services, transitioning from static fixed allocation to dynamic adaptive allocation.
2Productivity
If the radio frame structure uses fixed allocation units, then the system is easier to operate and maintain, but it results in inefficiency and inability to satisfy low latency and hyper connection requirements
Solution Approach 1:
The patent applies local quality by assigning different allocation units and frame structures to different service types locally. First type radio frames with first allocation units are used for certain services, while second type radio frames with second allocation units are used for other services with different requirements. This localized customization enables high productivity for specific services without requiring the entire system to become overly complex.
3Quantity of substance
If radio resources are not sliced according to service types, then the system maintains simpler resource management, but it leads to poor resource utilization and inability to provide customized service quality
Solution Approach 1:
The patent applies segmentation by slicing radio resources into different types based on service requirements. Resources are segmented into first type resources and second type resources, each optimized for specific services. This segmentation improves frequency resource utilization efficiency by matching resource characteristics to service needs while maintaining structured management through clear categorization.
