Terminal Device Radio Link Performance Reporting for Access Network Scheduling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in effectively managing radio link performance between client terminal devices and Wi-Fi terminal devices, leading to suboptimal user experience due to inadequate scheduling based on transmission performance.
Innovation Solution
A method where a terminal device reports performance parameter values, such as throughput rate and packet loss rate, to an access network device, allowing it to schedule devices with desirable transmission performance at high priority, thereby improving user experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the access network device schedules terminal devices without considering radio link performance, then the scheduling process is simple, but user experience deteriorates due to suboptimal resource allocation
Solution Approach 1:
The terminal device measures radio link performance parameters (throughput rate, packet loss rate) and feeds back this information to the access network device. The access network device then uses this feedback to dynamically adjust scheduling priorities, ensuring that terminal devices with better radio link performance receive higher priority scheduling. This feedback mechanism resolves the contradiction by enabling performance-based scheduling without significantly complicating the scheduling process.
2Reliability
If the access network device prioritizes terminal devices with better radio link performance, then user experience improves, but the device complexity increases due to additional performance measurement and reporting requirements
Solution Approach 1:
The terminal device autonomously measures its own radio link performance parameters (throughput rate, packet loss rate) and generates reports without requiring external assistance from the access network device. This self-service approach reduces the complexity burden on the network side while still enabling performance-based scheduling. The terminal device uses its existing measurement capabilities to generate performance reports, minimizing additional complexity.
3Measurement precision
If the terminal device reports detailed performance parameter values, then the access network device can make accurate scheduling decisions, but the loss of information increases due to additional signaling overhead
Solution Approach 1:
The terminal device calculates separate performance parameters for different services (first service throughput rate, second service packet loss rate) and reports them selectively based on service requirements. The access network device uses these localized performance metrics to make scheduling decisions specific to each service type. This approach maintains measurement precision for critical parameters while reducing overall signaling overhead by reporting only the most relevant performance metrics.
