Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication networks, extended reality (XR) data transmission faces challenges in maintaining synchronization and dependency between data packets, leading to degraded user experience when packets are lost or delayed.
Innovation Solution
A data transmission method involving protocol data encapsulation and identification information to ensure integrity transmission of data units with synchronization requirements, ensuring that data units with the same identification information are transmitted as a whole, thereby maintaining synchronization and improving user experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If data packets are transmitted independently without integrity constraints, then transmission efficiency is improved, but data synchronization and dependency requirements cannot be met
Solution Approach 1:
The patent segments data into data units with identical identifiers that must be transmitted together as a group. This segmentation ensures that dependent data packets maintain synchronization while allowing independent transmission of complete data units, resolving the contradiction between transmission efficiency and data synchronization reliability.
Solution Approach 2:
The patent merges multiple data packets with identical identifiers into a single transmission unit. By combining these packets and transmitting them together, the system ensures data integrity and synchronization requirements are met while maintaining efficient transmission through unified packet handling.
2Reliability
If protocol data encapsulation is performed to ensure data integrity, then data synchronization is improved, but device complexity increases
Solution Approach 1:
The patent performs protocol data encapsulation in advance on data units before transmission. By pre-encapsulating data with identical identifiers into unified packets, the system ensures data integrity and simplifies subsequent transmission processing, reducing the complexity burden during actual data transmission.
3Reliability
If all data packets are transmitted as a whole to meet synchronization requirements, then data dependency is improved, but transmission resources are wasted
Solution Approach 1:
The patent applies different transmission strategies to different data units based on their identifiers. Data units with identical identifiers are transmitted together as a group, while other data units follow standard transmission protocols. This localized approach ensures data dependency is met for critical synchronized data without unnecessarily consuming transmission resources for all data packets.
