Radio Resource Allocation for 5G Slice Interference Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In local 5G networks, efficiently managing radio resources to meet varying quality of service (QoS) requirements while minimizing interference between slices is challenging, leading to decreased frequency utilization efficiency and potential quality degradation.
Innovation Solution
A control device and method that estimate and manage radio resource allocation across base stations, prioritizing slices based on requested quality, and strategically allocate resources to minimize interference by using a network management system (NMS) to optimize radio resource allocation and interference control between cells.

Engineering Contradiction Analysis
1Adaptability or versatility
If radio resources are allocated to multiple slices with different QoS requirements, then service diversity and quality are improved, but interference between slices increases and frequency utilization efficiency decreases
Solution Approach 1:
The patent segments radio resources into three distinct types (first resources for high QoS slices, second resources for low QoS slices, and third restricted resources) to separate and manage different service requirements. This segmentation allows high QoS slices to receive dedicated resources while low QoS slices use remaining resources, thereby reducing inter-slice interference while maintaining service diversity.
Solution Approach 2:
The patent applies local quality by allocating different resource types to different slices based on their specific QoS requirements. High QoS slices receive first resources with guaranteed quality, while low QoS slices are allocated second resources, ensuring each slice receives appropriate quality locally rather than uniform resource allocation.
2Reliability
If radio resources are allocated to meet high QoS requirements, then service quality is improved, but frequency utilization efficiency decreases
Solution Approach 1:
The patent applies partial action by allocating first resources (guaranteed resources) only to the extent needed for high QoS slices, rather than reserving excessive resources. The remaining resources are dynamically allocated as second resources to low QoS slices, achieving partial allocation that balances service quality with efficient resource utilization.
Solution Approach 2:
The patent implements dynamic resource allocation where the allocation of first, second, and third resources is adjusted based on real-time QoS requirements and interference conditions. The control device dynamically determines resource types and allocation amounts, allowing the system to adapt to changing conditions and optimize both service quality and frequency utilization efficiency.
3Object-generated harmful factors
If interference control measures are implemented between base stations, then interference is reduced, but system complexity increases
Solution Approach 1:
The patent controls interference by changing resource allocation parameters - specifically by assigning different resource types (first, second, third resources) to different slices and base stations. The control device adjusts allocation parameters based on estimated interference amounts, achieving interference control through parameter optimization rather than complex structural modifications.

AI summary
A control device in a communication system including base station devices and terminal devices includes a processor configured to: calculate a needed radio resource amount of each slice classified based on requested quality; estimate an amount of interference between the base station devices, an amount of interference between the base station devices and the terminal devices, and an amount of interference between the terminal devices; allocate, in radio resources of a first base station device, a first resource for a first slice, a second resource for a second slice, and a restricted resource to which restrictions are imposed on use, based on a result of the estimation; and allocate a resource other than the second resource and the restricted resource as the first resource, and allocates a resource that is allocated in a second base station device and has influence on interference with the second slice.
