Delay-Aware Scheduling for XR Network Data Bursts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for artificial, mixed, and virtual reality experiences face challenges in managing data communication delays, which affect the quality of service by increasing latency and causing data to be discarded, leading to reduced quality of experience.
Innovation Solution
Implementing a method that uses delay-aware scheduling by allocating data bursts to a buffer with timers and indices, allowing for efficient communication of remaining time information, reducing overhead by minimizing the need for explicit timer assignment in periodic data bursts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If remaining time information is explicitly assigned to each data burst, then timing control precision is improved, but communication overhead increases
Solution Approach 1:
The patent merges the remaining time information of multiple periodic data bursts into a single indicator transmitted by the network device. Instead of separately assigning timers to each burst, the system combines timing information for multiple bursts (e.g., using a group timer or relative timing offset) into one communication event, thereby maintaining precise timing control while significantly reducing overhead.
Solution Approach 2:
The patent makes the timing indicator universal by designing it to serve multiple data bursts simultaneously. A single timing indicator can represent the remaining time for a group of periodic data bursts, allowing the same communication mechanism to handle multiple timing assignments without repetition. This multi-functional approach reduces the frequency of timing information transmission while maintaining control precision.
2Reliability
If data is transmitted according to periodic schedule, then quality of service is improved, but data may be discarded after becoming stale
Solution Approach 1:
The patent introduces dynamic timing adjustment mechanisms that allow the system to adapt to changing conditions. The network device can dynamically modify timing indicators based on actual network conditions, device status, and data urgency. This dynamic approach enables the system to maintain periodic scheduling reliability while preventing data from becoming stale by adjusting transmission timing in real-time based on current conditions.
Solution Approach 2:
The patent implements feedback mechanisms where the receiving device monitors data freshness and timing accuracy, then feeds this information back to the network device. This feedback loop enables the system to detect when data might become stale and adjust future timing indicators accordingly, ensuring that periodic scheduling maintains quality of service without transmitting outdated information.

AI summary
Disclosed herein are aspects related to a device that can include a wireless communication interface and one or more processors. The one or more processors can allocate at least a first data burst and a second data burst to a data buffer. The one or more processors can assign a timer corresponding to an amount of time for output of the first data burst until one or more timing criteria expire. The one or more processors can assign, responsive to the first data burst and the second data burst each representing periodic network traffic, an index indicative of the position of the second data burst in the data buffer relative to the first data burst. The wireless communications interface can transmit the first data burst, the timer for the first data burst, the second data burst, and the index for the second data burst.
