Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing scheduling algorithms for extended reality (XR) services fail to meet the high video frame correct ratio requirements, leading to low user satisfaction and resource wastage due to scheduling terminals with poor channel quality.
Innovation Solution
Determine a scheduling priority for terminals based on their instantaneous rate and service type, prioritizing terminals with high instantaneous rates to maximize correctly transmitted video frames and meet the video frame correct ratio requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing scheduling algorithms (RR or PF) are used to ensure scheduling fairness among terminals, then all terminals including those with poor channel quality receive scheduling opportunities, but the video frame correct ratio requirement of XR service cannot be met and system performance deteriorates
Solution Approach 1:
The patent changes the scheduling parameter from equal opportunity (RR) or fairness-based (PF) to instantaneous rate-based prioritization. By using instantaneous rate as the scheduling parameter, terminals with better channel conditions are preferentially scheduled, directly improving video frame correct ratio while avoiding waste on terminals with poor channel quality
Solution Approach 2:
The patent implements dynamic scheduling where the scheduling priority is continuously adjusted based on the instantaneous rate of each terminal. This dynamic adaptation allows the system to respond to changing channel conditions and always schedule the terminal most likely to achieve the video frame correct ratio requirement at any given moment
2Ease of operation
If terminals with poor channel quality are scheduled to ensure fairness, then scheduling opportunities are provided to all terminals, but resource wastage occurs and user satisfaction rate decreases
Solution Approach 1:
The patent changes the scheduling decision parameter from fairness metrics to instantaneous rate metrics. This parameter change enables the system to identify and prioritize terminals that can actually utilize the scheduled resources effectively, eliminating waste on terminals with poor channel conditions while maintaining operational simplicity
Solution Approach 2:
The patent applies partial scheduling action by selectively scheduling only those terminals that meet the instantaneous rate threshold for successful XR service transmission. Rather than providing equal opportunities to all terminals, the system provides scheduling action only where it will be effective, reducing resource waste while maintaining ease of operation through clear rate-based criteria

AI summary
This disclosure provides a scheduling transmission method and an apparatus. According to the method, a scheduling priority of a terminal is determined based on an instantaneous rate of the terminal and a service type of a first service of the terminal, and the first service is transmitted with the terminal based on the scheduling priority of the terminal. The instantaneous rate of the terminal is positively correlated with the scheduling priority of the terminal, and a target video frame correct ratio of the first service is greater than a first threshold. The solutions of this application can be widely used in the fields of communication technologies, artificial intelligence, Internet of vehicles, Internet of smart home, and the like.
