Wireless Resource Utilization Calculation for Real 5G Cell Load
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The utilization rate of wireless resources in 5G networks, calculated based on maximum network capability, fails to accurately reflect the actual load situation due to variations in geographical environments and user distribution.
Innovation Solution
Determine the utilization rate by calculating channel non-space division and space division occupied wireless resources, along with channel available wireless resources using maximum scheduling layer numbers within a statistical period, considering geographical limitations and user distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the utilization rate is calculated based on maximum network capability (full bandwidth PRB and maximum configured layers), then the calculation method is simple, but the utilization rate is too low to truly reflect the network load situation
Solution Approach 1:
The patent changes the calculation parameters from static maximum capability values to dynamic actual usage values. Specifically, it uses the maximum scheduling layer number actually configured for the cell within the statistical period instead of the maximum possible layers, and calculates available PRBs based on actual bandwidth configuration rather than full bandwidth. This transforms the utilization rate from a theoretical maximum-based metric to an actual usage-based metric, significantly improving accuracy while maintaining reasonable calculation complexity.
2Measurement precision
If the maximum scheduling layer number actually configured for the cell is used instead of maximum capability, then the utilization rate accurately reflects network load, but the calculation becomes more complex
Solution Approach 1:
The patent performs preliminary actions by collecting and storing the maximum scheduling layer number for each time slot within the statistical period before calculating the utilization rate. The network device accumulates this data during the statistical period, then determines the maximum value across all time slots. This preliminary data collection and processing simplifies the final calculation step while ensuring accurate reflection of actual network load conditions.
Solution Approach 2:
The patent introduces an intermediary calculation step that determines the maximum scheduling layer number across multiple time slots as a mediator between raw measurement data and the final utilization rate. This intermediary value (maximum layer number over the statistical period) serves as a bridge that translates complex time-varying scheduling data into a single representative parameter for utilization calculation, simplifying the overall process while maintaining accuracy.
