Radio Terminal Selection for Ultra-Dense Antenna Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In ultra-high-density distributed antenna systems, existing methods for selecting radio terminals for scheduling often prioritize those with favorable radio quality, leading to poor service quality for terminals with high communication quality but poor radio quality, resulting in degraded service quality and increased processing load.
Innovation Solution
A control apparatus that selects radio terminals based on predetermined criteria for service quality, determining whether each terminal meets delay requirements and allocating resources accordingly, thereby reducing the number of terminals for scheduling without degrading service quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If radio terminals with favorable radio quality are preferentially selected for scheduling, then the processing load is reduced, but service quality for radio terminals with poor radio quality degrades
Solution Approach 1:
The patent changes the selection criterion from radio quality alone to a composite criterion that includes both radio quality and service quality parameters. The selection unit evaluates multiple parameters including delay requirements, transmission opportunities, and radio quality to select radio terminals for scheduling, thereby resolving the contradiction between processing efficiency and service quality.
Solution Approach 2:
The patent introduces dynamic selection criteria that adapt based on service quality requirements. The selection unit dynamically adjusts which radio terminals are selected for scheduling by evaluating whether delay requirements are met and whether transmission opportunities have been provided, making the selection process flexible rather than static based solely on radio quality.
2Device complexity
If the number of radio terminals for scheduling is reduced, then processing load decreases, but service quality for some radio terminals degrades
Solution Approach 1:
The patent changes the selection criterion from radio quality alone to a composite criterion that includes both radio quality and service quality parameters. The selection unit evaluates multiple parameters including delay requirements, transmission opportunities, and radio quality to select radio terminals for scheduling, thereby resolving the contradiction between processing efficiency and service quality.
Solution Approach 2:
The patent incorporates feedback mechanisms where the selection unit continuously evaluates whether delay requirements are met and whether transmission opportunities have been provided to radio terminals. This feedback loop ensures that service quality is maintained while managing processing load, as the selection criteria are adjusted based on observed service quality metrics.
3Productivity
If radio resources are allocated based on radio quality, then communication efficiency improves, but service quality for terminals with poor radio quality deteriorates
Solution Approach 1:
The patent changes the resource allocation criterion from radio quality alone to a composite criterion that includes both radio quality and service quality parameters. The allocation unit considers delay requirements, transmission opportunities, and radio quality when allocating radio resources, ensuring that terminals with poor radio quality but high service quality requirements receive appropriate resources.
Solution Approach 2:
The patent introduces dynamic selection criteria that adapt based on service quality requirements. The selection unit dynamically adjusts which radio terminals are selected for scheduling by evaluating whether delay requirements are met and whether transmission opportunities have been provided, making the selection process flexible rather than static based solely on radio quality.
