Solution Overview

Problem

Current methods fail to determine CPU occupancy for CSI reports corresponding to multiple sub-configurations in a CSI report configuration, which is essential for optimizing network performance.

Innovation Solution

A terminal determines CPU occupancy by analyzing at least two sub-configurations in a CSI report configuration, considering time periods and CPU usage for each CSI report, allowing staggered CPU occupation based on spatial adaptation patterns.

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple sub-configurations are used in CSI report configuration to enable different measurement hypotheses, then the system can obtain multiple CSI reports for better scheduling decisions, but the CPU occupancy increases and resource management becomes complex

Engineering Contradiction:
Improvemeasurement hypothesesVSAvoidCPU occupancy management
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent segments the CPU occupancy determination into separate components: each sub-configuration's CPU occupancy is calculated independently based on its specific parameters (number of CSI reports, spatial adaptation patterns, etc.), then the total CPU occupancy is obtained by summing these segmented values. This segmentation approach simplifies the management of complex multi-sub-configuration scenarios.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces specific parameters to quantify CPU occupancy characteristics, including the number of CSI reports per sub-configuration, the number of spatial adaptation patterns, and the time period of CPU occupancy. By changing and adjusting these parameters, the system can flexibly manage CPU resources while supporting multiple measurement hypotheses.

Inventive Principle:
Principle #35Parameter changes

2Productivity

If the terminal performs measurements based on multiple sub-configurations, then multiple CSI reports can be generated for network optimization, but the time period and quantity of CPU occupancy increase

Engineering Contradiction:
ImproveCSI report generationVSAvoidCPU occupancy time period
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The patent performs preliminary calculation of CPU occupancy for each sub-configuration before actual CSI report generation. By pre-determining the CPU resources required based on the number of spatial adaptation patterns and CSI reports per sub-configuration, the system can plan and allocate CPU resources efficiently, avoiding excessive or redundant CPU occupancy during execution.

Inventive Principle:
Principle #10Preliminary action

3Measurement precision

If detailed CPU occupancy determination is implemented for each sub-configuration, then resource management precision improves, but the calculation complexity and processing overhead increase

Engineering Contradiction:

Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent divides the CPU occupancy determination process into segmented calculations for each sub-configuration, where each segment considers only the relevant parameters for that specific sub-configuration (number of CSI reports, spatial adaptation patterns). This segmented approach achieves precise CPU occupancy determination without requiring complex holistic analysis of all sub-configurations simultaneously.

Inventive Principle:
Principle #1Segmentation
